Cropley M, Dijk DJ, Stanley N (2006) Job strain, work rumination, and sleep in school teachers, European Journal of Work and Organizational Psychology 15 (2) pp. 181-196
The objectives of this study were, firstly, to examine the association between job strain and sleep quality in a sample of primary and secondary school teachers and, secondly, to assess whether the relationship between job strain and sleep quality is mediated or moderated by an individual's inability to "switch-off" from work-related issues during leisure time. School teachers (N= 143) completed an hourly record of their work-related thoughts over a workday evening between 5 p.m. and bedtime, and then rated their sleep quality the following morning. Individuals were classified as reporting high (n=46) or low (n=52) job strain using predetermined cut-off scores. Consistent with previous research, the results showed that both groups demonstrated a degree of unwinding and disengagement from work issues over the evening. However, compared to the low job strain group, the high job strain teachers took longer to unwind and ruminated more about work-related issues, over the whole evening, including bedtime. There was no difference in total sleep time between the groups, but high job strain individuals reported poorer sleep quality compared to low job strain individuals. With respect to the second objective, across the whole sample (N= 143), work rumination and job strain were significantly correlated with sleep quality, but work rumination was not found to mediate, or moderate the relationship between job strain and sleep quality. It was speculated that the initial low contribution of job strain to sleep quality (r = -.18) may have contributed to this null finding. The current findings may have implications for how we assess and manage sleep disturbance in stressed workers.
Cropley M, Cave Z, Ellis J, Middleton RW (2002) Effect of kava and valerian on human physiological and psychological responses to mental stress assessed under laboratory conditions., Phytother Res 16 (1) pp. 23-27
This study investigated whether kava or valerian could moderate the effects of psychological stress induced under laboratory conditions in a group of healthy volunteers. Fifty-four participants performed a standardized colour/word mental stress task on two occasions 1 week apart. Blood pressure (BP), heart rate (HR) and subjective ratings of pressure were assessed at rest and during the mental stress task. Following the first session (time 1 = T1), individuals took a standard dose of kava (n = 18), or valerian (n = 18) for 7 days, while the remainder acted as controls (n = 18). Differences in BP and HR from resting levels were calculated as reactions to the stress task at both time points. At the second session (time 2 = T2) there was a significant decrease in systolic BP responsivity in both the kava and valerian groups relative to T1, but there were no significant reductions in diastolic BP. Between T1 and T2, the HR reaction to mental stress was found to decline in the valerian group but not in the kava group. Individuals taking kava or valerian reported less pressure during the task at T2 relative to T1. There were no significant differences in BP, HR or subjective reports of pressure between T1 and T2 in the controls. Behavioural performance on the colour/word task did not change between the groups over the two time points. The results suggest that kava and valerian may be beneficial to health by reducing physiological reactivity during stressful situations.
Theadom A, Cropley M (2010) 'This constant being woken up is the worst thing' - experiences of sleep in fibromyalgia syndrome, Disability and Rehabilitation 32 (23) pp. 1939-1947 Informa Healthcare
Purpose.?Sleep disturbance affects a high proportion of people with fibromyalgia syndrome (FMS). This study aims to explore people's perceptions of their sleep quality and the influence sleep has on their symptoms and daily lives.

Method.?Semi-structured interviews were conducted with sixteen participants diagnosed with primary FMS, covering all aspects of the sleep experience. The audio recorded qualitative interviews were transcribed verbatim and analysed using interpretative phenomenological analysis.

Results.?Poor sleep dominated participants' lives, affecting levels of pain and fatigue, engagement in daily activities and ability to cope. Participants reported experiencing blocks of sleep, with the most profound difficulty for participants being able to go back to sleep after a night time awakening. They also felt a lack of control in their ability to manage their sleep difficulties and use of day-time napping appeared to be the only perceived beneficial coping strategy for relieving daytime sleepiness and symptoms of fatigue.

Conclusions.?Greater emphasis on screening for sleep disorders and how to manage poor sleep is needed in rehabilitation programmes provided for patients with FMS.

BACKGROUND: Mind-body interventions are based on the holistic principle that mind, body and behaviour are all interconnected. Mind-body interventions incorporate strategies that are thought to improve psychological and physical well-being, aim to allow patients to take an active role in their treatment, and promote people's ability to cope. Mind-body interventions are widely used by people with fibromyalgia to help manage their symptoms and improve well-being. Examples of mind-body therapies include psychological therapies, biofeedback, mindfulness, movement therapies and relaxation strategies. OBJECTIVES: To review the benefits and harms of mind-body therapies in comparison to standard care and attention placebo control groups for adults with fibromyalgia, post-intervention and at three and six month follow-up. SEARCH METHODS: Electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), EMBASE (Ovid), PsycINFO (Ovid), AMED (EBSCO) and CINAHL (Ovid) were conducted up to 30 October 2013. Searches of reference lists were conducted and authors in the field were contacted to identify additional relevant articles. SELECTION CRITERIA: All relevant randomised controlled trials (RCTs) of mind-body interventions for adults with fibromyalgia were included. DATA COLLECTION AND ANALYSIS: Two authors independently selected studies, extracted the data and assessed trials for low, unclear or high risk of bias. Any discrepancy was resolved through discussion and consensus. Continuous outcomes were analysed using mean difference (MD) where the same outcome measure and scoring method was used and standardised mean difference (SMD) where different outcome measures were used. For binary data standard estimation of the risk ratio (RR) and its 95% confidence interval (CI) was used. MAIN RESULTS: Seventy-four papers describing 61 trials were identified, with 4234 predominantly female participants. The nature of fibromyalgia varied from mild to severe across the study populations. Twenty-six studies were classified as having a low risk of bias for all domains assessed. The findings of mind-body therapies compared with usual care were prioritised.There is low quality evidence that in comparison to usual care controls psychological therapies have favourable effects on physical functioning (SMD -0.4, 95% CI -0.6 to -0.3, -7.5% absolute change, 2 point shift on a 0 to 100 scale), pain (SMD -0.3, 95% CI -0.5 to -0.2, -3.5% absolute change, 2 poi
Theadom A, Cropley M, Humphrey KL (2007) Exploring the role of sleep and coping in quality of life in fibromyalgia., J Psychosom Res 62 (2) pp. 145-151
OBJECTIVE: The objective of this study was to explore the effect of sleep and coping on health-related quality of life in fibromyalgia syndrome (FMS). METHODS: Patients diagnosed with FMS (N=101) completed the Positive and Negative Affect Schedule, the Pittsburgh Sleep Quality Index, the COPE, and the Medical Outcomes Study--Short-Form Health Survey for the previous month. RESULTS: Poor sleep quality was reported by 99% of participants. Sleep quality was significantly predictive of pain, fatigue, and social functioning in patients with FMS. Active coping, planning, acceptance, and seeking instrumental and emotional social support were not predictive of health outcomes in FMS. However, the use of restraint coping was predictive of poorer physical functioning. CONCLUSION: Sleep quality has significant implications for health-related quality of life in FMS. The use of coping strategies contributed little to the models' ability to predict health outcomes in FMS. Interventions designed to improve sleep quality may help to improve health-related quality of life for patients with FMS.
Haasova M, Warren FC, Ussher M, Janse Van Rensburg K, Faulkner G, Cropley M, Byron-Daniel J, Everson-Hock ES, Oh H, Taylor AH (2014) The acute effects of physical activity on cigarette cravings: Exploration of potential moderators, mediators and physical activity attributes using individual participant data (IPD) meta-analyses, Psychopharmacology 231 (7) pp. 1267-1275
Rationale: The effects of acute bouts of physical activity (PA) on Strength of Desire (SoD) and Desire to Smoke (DtS) using individual participant data (IPD) from 19 acute randomised controlled studies were quantified. However, there is a need to identify factors influencing this relationship. Objectives: To understand who most benefits from PA, whether changes in affect mediate these effects and whether any specific attributes of PA are associated with cigarette cravings. Methods: IPD (n = 930) contributed to one-stage IPD meta-analyses. Participants engaging in PA were compared against controls, using post-intervention DtS and SoD (when DtS is not available) with baseline adjustments. The craving scales were linearly rescaled to 0-100 % (a mean difference between groups of -10 would indicate that post-intervention cravings were 10 % lower in the PA compared with the control group). Demographic, smoking and other characteristics were examined as predictors and potential moderators, whereas change in affect was considered as a mediator. PA was categorised according to type, duration and intensity, to determine PA attributes associated with cravings reduction. Results: None of the included covariates were shown to moderate or mediate the effects of PA. Intensity of PA was significantly associated with a reduction in cravings; moderate and vigorous intensity PA offered the most benefits. A one-stage IPD meta-analysis yielded effect sizes of -9.22 (-15.24; -3.20) for light, -34.57 (-42.64; -26.50) for moderate and -31.29 (-38.00; -24.57) for vigorous intensity in comparison with controls. Conclusions: Moderate intensity PA could be recommended to all smokers regardless of demographic, smoking and other characteristics. © 2014 Springer-Verlag Berlin Heidelberg.
Ellis J, Cropley M (2002) An examination of thought control strategies employed by acute and chronic insomniacs., Sleep Med 3 (5) pp. 393-400
STUDY OBJECTIVES: Theoretical accounts of the progression of insomnia from acute to chronic are lacking. A framework is proposed and tested to examine differences in cognitive coping styles between acute and chronic insomniacs and the relation of cognitive processing and sleep hygiene to causal attributions of insomnia. METHOD: In a cross-sectional design, the relationship among sleep disturbance, causal attributions and various psychological and behavioural variables was examined in a convenience sample of acute and chronic insomniacs from the general population (N=308). RESULTS: Negative appraisals and the cognitive coping styles 'Worry' and 'Punishment' were found to be associated with both acute and chronic insomnia, whereas 'Distraction' as a cognitive coping strategy significantly reduced reports of chronic insomnia. The results are discussed in relation to multi-level interventions and future directions in theory, research and application.
Rydstedt LW, Cropley M, Devereux JJ, Michalianou G (2009) The effects of gender, long-term need for recovery and trait inhibition-rumination on morning and evening saliva cortisol secretion, Anxiety, Stress and Coping 22 (4) pp. 465-474 Taylor & Francis
The aim of this study was to investigate the long-term effects of need for recovery from work and trait rumination on saliva cortisol secretion. The sample consisted of 76 white-collar workers, 52 men and 24 women who had previously provided baseline data four years earlier and volunteered to participate in the present study. In the present study, saliva cortisol secretion was measured over seven consecutive days, on awakening, and at 10 p.m. No relationships were found between the independent variables and morning saliva cortisol levels. High trait rumination at baseline, however, was significantly related to higher evening cortisol levels for both women and men. Baseline need for recovery from work was strongly related to evening cortisol secretion for women, but in the opposite direction than expected. The present results add to the small but equivocal body of literature that has examined the long-term effects of work strain on cortisol secretion.
Cropley M, Rydstedt LW, Devereux JJ, Middleton B (2013) The Relationship Between Work-Related Rumination and Evening and Morning Salivary Cortisol Secretion, Stress and Health
The perseverative cognition hypothesis suggests that worry/ruminative thinking prolongs stress-related physiological activation. This study explored the association of work-related rumination with salivary cortisol sampled at 10pm and the cortisol awakening response (CAR) the following morning. On a mid-week evening, 108 school teachers completed a small diary about their work-related thoughts and gave a saliva cortisol sample at 10pm. The following morning, they gave four additional saliva samples: at awakening and at 15, 30 and 45min after awakening, along with a rating of their anticipatory thoughts about work. The CAR was calculated as the percentage increase in cortisol secretion from awakening to 30min, and the sample was divided at their respective medians to classify participants into low and high rumination groups. Cortisol secretion was found to be significantly greater in the high compared with the low ruminators at 10pm, and this effect was not related to leisure activities or work patterns during the evening. For the morning measures, high ruminators demonstrated a flattened CAR relative to the low ruminators, and this effect appeared to be associated with sleep disturbance during the night. Ruminating about work-related issues is associated with cortisol secretion, and our findings support the perseverative cognition hypothesis. © 2013 John Wiley & Sons, Ltd.

Pravettoni G, Cropley M, Leotta SN, Bagnara S (2007) The differential role of mental rumination among industrial and knowledge workers., Ergonomics 50 (11) pp. 1931-1940
The nature of work has been changing. It is becoming more and more uncertain, complex, cognitively demanding, disperse in space and in time, and diverse for the people involved. It requires diffuse decision making and responsibility. Knowledge and creative work, instead of industrial, currently occupies the majority of workforce. A recent NIOSH report (2002) claims that the changing nature of work asks for new research, tools and methods for evaluating the impact of its transformations on workers' health and safety. Following this claim, the current paper investigates the process of recovery from fatigue. Since it is known that the quality of recovery may be highly impoverished by the presence of persisting and pervasive mental activity, namely, by mental rumination, the investigation focuses on the possible differential characteristics of rumination among industrial and knowledge workers. The results from a field study shows evidence that industrial and knowledge workers are differentially affected by rumination. It is suggested that rumination can be a promising early indicator of stress in knowledge occupations.
Costa M, Cropley M, Griffith J, Steptoe A (1999) Ambulatory blood pressure monitoring is associated with reduced physical activity during everyday life., Psychosom Med 61 (6) pp. 806-811
OBJECTIVE: The objective of this study was to assess the impact on noninvasive ambulatory blood pressure monitoring on physical activity measured objectively by use of triaxial accelerometers. METHODS: Twenty-four working men and women performed ambulatory blood pressure plus activity monitoring for 1 working day and evening and activity monitoring alone for a separate day and evening. Blood pressure measures were taken at 20-minute intervals during the day and 30-minute intervals in the evening and were accompanied by diary assessments of mood, location, and posture. Comparisons were made of energy expenditure on the 2 days and of activity levels during the minutes surrounding each blood pressure reading and diary completion. RESULTS: Energy expenditure assessed in terms of activity calories per hour was significantly lower during blood pressure plus activity monitoring compared with activity monitoring alone (mean 37.3, SD = 16.3 vs. mean = 43.0, SD = 18.7 kcal, respectively: p = .02). Energy expenditure was lower during the 4 minutes surrounding each blood pressure reading than in the intervals between blood pressure readings. However, energy expenditure was also lower in the intervals between blood pressure readings than during comparable times on the activity only monitoring day. Blood pressure, heart rate, and physical activity were moderately correlated within individuals. CONCLUSIONS: Ambulatory blood pressure recording using automated sphygmomanometers is associated with reduced physical activity during the monitoring day. This is due partly to regular periods of immobility during cuff inflation and deflation and diary completion and partly to more general self-imposed restrictions on activity. This pattern has implications for the representativeness of ambulatory blood pressure monitoring, and the construction of ambulatory monitoring diaries.
Aims: To examine the acute effects of a guided relaxation routine (body scan) on desire to smoke and tobacco withdrawal symptoms in overnight abstinent smokers. Design: Experimental. Participants: Thirty individuals reporting to smoke 10 or more cigarettes daily for at least 3 years. Intervention: Participants were assigned randomly to complete a 10-minute body scan (experimental group n = 15) or listen to a natural history passage for 10 minutes (control group n = 15). Measurement: Ratings of strength of desire to smoke and smoking withdrawal symptoms were assessed at baseline, immediately after the interventions, and 5, 10 and 15 minutes post-intervention. Findings: There was a significant group x time interaction for strength of desire to smoke. The mean desire to smoke rating was significantly lower in the body scan group relative to the control group immediately after the intervention, and 5 minutes post-intervention. The body scan group also reported lower ratings of irritability, tension and restlessness, relative to the controls. Conclusion: A brief body scan intervention reduces strength of desire to smoke and some tobacco withdrawal symptoms in temporarily abstaining smokers. The body scan may be beneficial as a technique for managing cigarette cravings and withdrawal. © 2007 The Authors.
Ussher M, Nunziata P, Cropley M, West R (2001) Effect of a short bout of exercise on tobacco withdrawal symptoms and desire to smoke., Psychopharmacology (Berl) 158 (1) pp. 66-72
RATIONALE: Previous research suggests that a long bout of vigorous intensity exercise may reduce tobacco withdrawal symptoms and desire to smoke during abstinence. OBJECTIVE: In the present study, we investigated whether a short bout of moderate intensity exercise reduced desire to smoke and withdrawal symptoms in abstaining smokers. METHODS: Seventy-eight smokers attended the laboratory in the afternoon having not smoked since the previous evening. They rated their desire to smoke and withdrawal symptoms immediately before, during and after 10 min of moderate intensity exercise on a stationary cycle (experimental condition), or after waiting passively (control condition 1) or watching a video (control condition 2). RESULTS: Ratings of desire to smoke and withdrawal symptoms decreased more in the experimental group than in both control groups, which did not differ from each other. The effect was evident at all measurement points and was maintained for at least 10 min following exercise. CONCLUSION: A single bout of 10 min of moderate intensity exercise has a rapid and measurable effect on desire to smoke and tobacco withdrawal symptoms in abstaining smokers. Short bouts of exercise may be useful in helping to reduce desire to smoke and withdrawal symptoms during smoking cessation.

Aims: To conduct an updated systematic review and the first meta-analysis of experimental trials investigating the acute effects of short bouts of physical activity (PA) on strength of desire (SoD) and desire to smoke (DtS) using individual participant data (IPD). Methods: A systematic review of literature and IPD meta-analyses included trials assessing the acute effects of shorts bouts of PA on SoD and DtS among temporarily abstaining smokers not using pharmaceutical aids for smoking cessation. Authors of eligible studies were contacted and raw IPD were obtained. Two-stage and one-stage IPD random-effects meta-analyses were conducted. Participants engaging in PA were compared against control participants, using post-intervention SoD and DtS with baseline adjustments. Results: A two-stage IPD meta-analysis assessing effects of PA on SoD yielded an average standardized mean difference (SMD) between PA and control conditions (across 15 primary studies) of -1.91 [95% confidence interval (CI): -2.59 to -1.22]. A two-stage IPD meta-analysis assessing effects of PA on DtS yielded an average SMD between PA and control conditions (across 17 primary studies) of -2.03 (95% CI: -2.60 to -1.46). Additional meta-analyses, including those using a one-stage model, those including only parallel arm studies and meta-analyses comparing only moderate exercise against a control condition, showed significant craving reduction following PA. Despite a high degree of between-study heterogeneity, effects sizes of all primary studies were in the same direction, with PA showing a greater reduction in cravings compared with controls. Conclusions: There is strong evidence that physical activity acutely reduces cigarette craving. © 2012 Society for the Study of Addiction.
Purvis LJ, Cropley M (2003) The psychological contracts of National Health Service nurses., J Nurs Manag 11 (2) pp. 107-120
AIMS: Following the psychological contract model of the employee-employer exchange relationship is offered as a means of understanding the expectations of a UK sample of 223 National Health Service (NHS) nurses in association with their leaving intentions. DESIGN AND METHODS: A pilot study involving 21 NHS nurses, using the repertory grid technique was conducted to elicit contract expectations. Twenty-nine categories of expectation were identified through content analysis. The study proper, employed a survey developed on the basis of results from the pilot study to identify contract profiles among 223 nurses from three London/South-east NHS hospitals, using the Q-sort method. Type of contract held (relational/transactional), satisfaction (job and organization), and leaving intentions were also examined. RESULTS: Q-analysis yielded four contract profiles among the nurses sampled: 'self-development and achievement'; 'belonging and development'; 'competence and collegiality' and 'autonomy and development'. Correlation analysis demonstrated that leaving intentions were associated with a need for personal autonomy and development, and the violation of expectations for being appreciated, valued, recognized and rewarded for effort, loyalty, hard-work and achievement, negative endorsement of a relational contract, positive endorsement of a transactional contract, and job and organizational dissatisfaction. CONCLUSION: Findings illustrate the diagnostic utility of the term psychological contract for understanding the expectations of NHS nurses. The potential significance of these findings for managing nurse retention is highlighted.
Cropley M, MacLeod AK (2003) Dysphoria, attributional reasoning and future event probability, CLINICAL PSYCHOLOGY & PSYCHOTHERAPY 10 (4) pp. 220-227 JOHN WILEY & SONS LTD
There is growing interest in how workers recover and unwind from work during leisure, as poor unwinding has been associated with negative health. This research explores the recovery process to gain a greater understanding of how individuals switch?off from work?related thoughts post work. Specifically, we conducted interviews with workers who habitually find it difficult to switch?off from work (i.e. high ruminators), and workers who find it easy to switch?off from work (i.e. low ruminators). Three master themes were elicited using Interpretative Phenomenological Analysis: (1) work philosophy, (2) coping strategies and (3) coping outcomes. The findings revealed differences in core beliefs about work; high ruminators perceive blurred boundaries between work and home life, and they allowed work to mentally predominate during their leisure time, whereas low ruminators viewed their work and leisure as two distinct spheres, and actively developed strategies to switch?off and disengage from work. Both high and low ruminators acknowledged the health benefits of unwinding post work, yet only low ruminators managed to successfully do so. It was concluded that there is a need for organisations to educate their employees, particularly high ruminators, about the importance of strategic unwinding post work to optimise the quality of leisure time and prevent them from becoming fatigued and burnt out.
Daniel JZ, Cropley M, Fife-Schaw CR (2006) The effect of exercise in reducing desire to smoke and cigarette withdrawal symptoms is not caused by distraction, Addiction 101 (8) pp. 1187-1192
Aims and design Moderate-intensity exercise has been shown to reduce common smoking withdrawal symptoms and desire to smoke in acutely abstinent smokers. The aim of the present study was to determine if this was caused by distraction. A secondary aim was to determine whether exercise-related changes in affect were related to a reduction in symptoms. Methods Forty 'sedentary' participants who had smoked at least 10 or more cigarettes per day for at least 3 years were assigned randomly to one of two groups. They completed either 10 minutes of moderate-intensity exercise on a stationary bicycle ergometer or 10 minutes of a cognitive distraction task ( paced visual serial addition task, PVSAT) after 11 - 15 hours of smoking abstinence. Participants rated smoking withdrawal symptoms and desire to smoke using standard scales at 10, 5 and 0 minutes before the experimental intervention, then at 5 and 10 minutes after the start of the intervention and 5 and 10 minutes after its completion. Findings Significant group x time interactions were observed for ratings of desire to smoke and several withdrawal symptoms ( irritability, depression, restlessness, difficulty concentrating and stress). There was a reduction in ratings during and immediately following exercise that was not observed with cognitive distraction. Also it was found the effects were not mediated by changes in affect observed in the exercise condition. Conclusions A brief bout of moderate-intensity exercise can lead to a rapid reduction in desire to smoke and withdrawal discomfort, which is not due to the distracting effect of exercise or the effects of mood. These findings support recommendations to smokers to use exercise as a means of helping cope with the difficulties encountered when they try to stop.
Objective: To evaluate the effectiveness of the Mitchell Method Relaxation Technique (MMRT) in reducing symptoms of fibromyalgia. Design: A randomised controlled trial was used to compare the effectiveness of self-administered MMRT (n= 67) with attention control (n = 66) and usual care (n = 56) groups. Main Outcome Measures: Primary outcomes included self-reported fatigue, pain, and sleep. Secondary outcomes were daily functioning, quality of life, depression, and coping, anxiety and perceived stress. Outcomes were assessed at baseline, post-intervention (four weeks) and follow-up (eight weeks).

Cropley M, Theadom A, Pravettoni G, Webb G (2008) The effectiveness of smoking cessation interventions prior to surgery: a systematic review., Nicotine & Tobacco Research 10 (3) pp. 407-412 Oxford Journals
The objective of this review was to evaluate the effectiveness of smoking cessation interventions prior to surgery and examine smoking cessation rates at 6 months follow-up. The Cochrane Library Database, PsycINFO, EMBASE, Medline, and Cinahl databases were searched using the terms: smok$, smoking cessation, tobacco, cigar$, preop$, operati$, surg$, randomi*ed control$ trial, intervention, program$, cessation, abstinen$, quit. Further articles were obtained from reference lists. The search was limited to articles on adults, written in English and published up to December 2006. Only randomized control trials (RCTs) that incorporated smoking cessation interventions to patients awaiting elective surgery were included. Seven studies met the inclusion criteria. Methodological quality was assessed by all the authors. The findings revealed that short-term quit rates (or a reduction by more than half of normal daily rate) ranged from 18% to 93% in patients receiving a smoking intervention (mean 55%), compared with a range of 2%-65% of controls (mean = 27.7%). Two studies examined smoking status at 6 months but these revealed no significant difference in abstinence rates between patients who had received an intervention and those that had not. Studies that incorporated counseling in addition to nicotine replacement therapy appeared to show greater benefits. It is concluded that smoking cessation interventions prior to surgery are effective in helping patients to quit smoking. However, such effects appear to be short-lived. Future research needs to examine intervention and patient factors to see whether tailoring the smoking cessation intervention specifically to the patient improves overall abstinence rates.
Kantermann T, Theadom A, Roenneberg T, Cropley M (2012) Fibromyalgia syndrome and chronotype: late chronotypes are more affected., Journal of Biological Rhythms 27 (2) pp. 176-179 Sage
Sleep has strong links to the symptomology of fibromyalgia syndrome (FMS), a diffuse musculoskeletal pain disorder. Information about the involvement of the circadian clock is, however, sparse. In this study, 1548 individuals with FMS completed an online survey containing questions on demographics, stimulant consumption, sleep quality, well-being and subjective pain, chronotype (assessed by the Munich ChronoType Questionnaire, MCTQ), and FMS impact. Chronotype (expressed as the mid-sleep-point on free days, corrected for sleep deficit on workdays, MSF(sc)) significantly correlated with stress-ratings, so-called "memory failures in everyday life," fatigue, FMS impact, and depression but not with anxiety. When chronotypes were categorized into 3 groups (early, intermediate, late), significant group differences were found for sum scores of perceived stress, memory failures in everyday life, fatigue, FMS impact, and depression but not anxiety, with late chronotypes being more affected than early chronotypes. Sleepiness ratings were highest in early chronotypes. Challenges of sleep quality and subjective pain were significantly increased in both early and late chronotypes. The results show that according to their reports, late chronotypes are more affected by fibromyalgia.
Griffith J, Steptoe A, Cropley M (1999) An investigation of coping strategies associated with job stress in teachers., Br J Educ Psychol 69 ( Pt 4) pp. 517-531
BACKGROUND: School teaching is regarded as a stressful occupation, but the perception of the job as stressful may be influenced by coping responses and social support. AIMS: To assess the associations between teacher stress, psychological coping responses and social support, taking into account the plaintive set engendered by negative affectivity. METHOD: Questionnaire survey of 780 primary and secondary school teachers (53.5% response rate). RESULTS: In stepwise multiple regression, social support at work and the coping responses behavioural disengagement and suppression of competing activities predicted job stress independently of age, gender, class size, occupational grade and negative affectivity. High job stress was associated with low social support at work and greater use of coping by disengagement and suppression of competing activities. CONCLUSIONS: It is suggested that behavioural disengagement and suppression of competing activities are maladaptive responses in a teaching environment and may actually contribute to job stress. Coping and social support not only moderate the impact of stressors on well-being but influence the appraisal of environmental demands as stressful.
Steptoe A, Cropley M, Griffith J, Kirschbaum C (2000) Job strain and anger expression predict early morning elevations in salivary cortisol., Psychosom Med 62 (2) pp. 286-292
OBJECTIVE: The objectives of this study were to test the hypothesis that high job demands and low job control (job strain) are associated with elevated free cortisol levels early in the working day and with reduced variability across the day and to evaluate the contribution of anger expression to this pattern. METHODS: One hundred five school teachers (41 men and 64 women) classified 12 months earlier as high (N = 48) or low (N = 57) in job strain according to the demand/control model sampled saliva at 2-hour intervals from 8:00 to 8:30 hours to 22:00 to 22:30 hours on a working day. Anger expression was assessed with the Speilberger State-Trait Anger Expression Inventory, and negative affect was also measured. RESULTS: Free cortisol was significantly elevated at 8:00 to 8:30 hours in the high job strain group but not at later times of the day or evening. After adjustment for age and negative affect, cortisol was an average of 21.7% higher early in the working day in the high job strain group. This effect was significantly greater in high job strain teachers, who also reported high anger-out. The cortisol decline from morning to evening was greater in the high than low job strain individuals. Independently of job strain, women had a higher cortisol concentration at 8:00 to 8:30 hours than men, whereas cortisol concentration was greater in men than women in the middle of the working day between 12:00 and 16:30 hours. CONCLUSIONS: Job strain is associated with elevated free cortisol concentrations early in the working day but not with reduced cortisol variability. The interaction with outward anger expression suggests that individual characteristics modulate the impact of chronic work stress on the hypothalamic-pituitary-adrenocortical system.

The topic of recovery from the demands of work has received considerable attention over recent years. In fact, it is now well-recognized that people need to recover from the strains of work. The relevance of ?recovery? from work has increased over the last decade, which can be largely attributed to management practices that have led to an intensification of work. In many occupations the demands are primarily of a cognitive nature (i.e. responsibility, information processing, and so on). As a consequence, approximately half of the working population complains about ?work pressure? (Paoli & Merllié, 2001).
This chapter aims to focus on the cognitive aspects of work and its relationship with recovery. It will be argued that, since the cognitive demands are dominant, ?thinking of work? is one of the main determinants for (absence of or delayed) recovery. In order to make this point we will start with a brief historic overview.
Cropley M, Steptoe A (2005) Social support, life events and physical symptoms: A prospective study of chronic and recent life stress in men and women, Psychology, Health and Medicine 10 (4) pp. 317-325
The objective of this study was to examine whether functional social support buffers the effects of chronic and recent life stress on physical symptom reporting in men and women and assess whether perceptions of support remain stable over time. A longitudinal design was used. Self-ratings of stressful experiences were completed every 3 months over a period of 1 year. Physical symptoms were assessed at 6 and 12 months, and perceptions of social support were measured at baseline and at 12 months. Three groups were formed on the basis of average stress values for the first and second 6 months of the year: chronic low stress, chronic high stress and a recent high-stressed group consisting of individuals who reported low stress for the first 6 months, but high stress for the second 6 months of the year. As expected, high life stress was associated with greater symptom reporting. Perceptions of support remained stable and did not decline over the 12 months. After controlling for negative affectivity and physical symptoms at 6 months, no main effects of social support were found on reported physical health. However, perceived social support did moderate physical symptom reporting in those reporting recent high stress. For chronically high-stressed individuals there was no significant difference in physical symptoms between those with high or low social support. It was concluded that social support moderates the impact of recent but not chronic life stress on physical symptom reporting. © 2005 Taylor & Francis Group Ltd.
Cropley M, Millward Purvis L (2003) Job strain and rumination about work issues during leisure time: A diary study, European Journal of Work and Organizational Psychology 12 (3) pp. 195-207 Taylor & Francis
Previous research has suggested that high job strain (high demand, low control at work) is associated with an inability to ?unwind? physiologically after work. It was speculated that one mechanism related to the ?unwinding process? is an individual's ability to ?cognitively switch-off? about work related issues after work. This hypothesis was tested in a diary study of primary and secondary school teachers who were asked to keep an hourly record of their work-related thoughts over a workday evening between 17.00 hrs and 21.00 hrs. As expected both groups demonstrated a degree of unwinding and disengagement from work issues over the evening. High strain (n = 34) teachers however took longer to unwind and ruminated more about work-related issues, relative to low job strain (n = 35) teachers. High job strain teachers also reported they had less personal control over what they were doing in the evening. Across the evening all individuals reported higher ruminative thoughts about work issues when alone than when with family and friends, but high strain teachers reported more ruminative cognitions when watching television and with family and friends than low strain teachers. The results could not be explained by work patterns as there was no difference in the number of hours worked in the evening between the two groups. It is argued that one reason why high job strain teachers failed to successfully unwind after work is that they ruminated more about work issues, than did low job strain teachers.

The long-term impact of role stress (conflict and ambiguity), cognitive rumination and their interaction were analysed upon morning and evening saliva cortisol secretion. The sample consisted of 52 male and 24 female British white-collars who had participated in a survey study on psychosocial working conditions 3.5 years earlier. Saliva cortisol secretion was measured over seven consecutive days with two measures: in the morning on awakening and at 22.00 hours. Stepwise linear multiple regression analyses was used for the statistical analyses. Role ambiguity at baseline and the interaction between role ambiguity and trait rumination contributed to explaining elevations in morning saliva cortisol secretion 3.5 years later (R(2) = 0.045; F = 4.57; p
Ellis J, Hampson SE, Cropley M (2007) The role of preoccupation in attributions for poor sleep., Sleep Med 8 (3) pp. 277-280
BACKGROUND AND PURPOSE: Studies examining the impact of daytime preoccupations with sleep are rare. The aim of the present study was to determine whether daytime preoccupations mediate the relationship between anxiety and attributions for poor sleep within older adults. METHOD: A cross-sectional study examined the mediational role of sleep preoccupations in the link between anxiety and attributions for poor sleep in a sample of late-life insomniacs (n=92). RESULTS: The findings show that a preoccupation with sleep during the day mediates the relationship between anxiety and both sleep effort and sleep pattern problem attributions but does not mediate cognitive arousal attributions for insomnia and only partially mediates the relationship between anxiety and physical tension attributions for insomnia. CONCLUSIONS: The results are discussed in terms of the existing models of insomnia and cognitive intervention strategies.
If perfectionists avoid engaging in preventive health behaviours, they may be putting their long-term health and well-being at risk. Correlational analyses based on a sample of 370 university students identified maladaptive perfectionism to be associated with decreased levels of engagement in preventive health behaviours, life satisfaction and well-being and increased levels of self-concealment and psychological distress. Adaptive perfectionism was associated with higher levels of engagement in preventive health behaviours. Self-concealment was identified as a partial mediator in the relationship between maladaptive perfectionism and both engagement in preventive health behaviours and psychological distress. Implications of the findings are discussed.

Inability to unwind about work during leisure time has been associated with a number of negative health outcomes. This study was concerned with a possible behavioural pathway between unwinding and disease and examined the relationship between work-related rumination and food choice. Work-related rumination is arguably a core to understanding the ?unwinding process?, and food choice is a well-established indicator of nutritional health. Two hundred and sixty-eight full-time workers from a range of white-collar occupations completed a self-report measure of ruminative thinking about work and an eating behaviour questionnaire. Three types of ruminative thinking were identified by factor analysis and labelled affective rumination, problem-solving pondering and detachment. In terms of food choice, high-relative to low-affective ruminators reported eating more unhealthy foods, and low detachers reported eating less cooked meals and more processed foods compared to high detachers. Problem-solving pondering was not associated with food choice, and none of the factors were associated with healthy food choice. It was concluded that failure to unwind from work is not necessarily related to unhealthy food choices. What appears to be the crucial factor is the type of perseverative thinking that people engage in post-work. Limitations and future directions are discussed.
Ellis J, Hampson SE, Cropley M (2007) The role of dysfunctional beliefs and attitudes in late-life insomnia., J Psychosom Res 62 (1) pp. 81-84
OBJECTIVES: This study examined the role of individual and combined sleep-related dysfunctional beliefs in late-life insomnia. METHODS: Older adults who responded to an advertisement in a magazine took part in a cross-sectional survey (N=382). Respondents completed self-report measures of dysfunctional beliefs about sleep (Dysfunctional Beliefs and Attitudes to Sleep Scale) as well as measures of their current sleep patterns. RESULTS: Overall, people with insomnia (PWI) endorsed more extreme ratings of dysfunctional beliefs than "good sleepers" did. However, some sleep-related dysfunctional beliefs did not discriminate PWIs from good sleepers nor were they related to experiencing a longer duration of insomnia. CONCLUSION: This article demonstrates that not all sleep-related dysfunctional beliefs are related to reporting insomnia and that some are not related to a longer reported duration of insomnia, possibly changing through personal experience. These preliminary results may have implications for tailoring the cognitive aspects of psychoeducational programmes for people with late-life insomnia.
In the process of recovery from work, rumination is considered as an important mediating variable in the relationship between work demands and psychological health outcomes. Past research differentiated affective rumination from problem-solving pondering. The aim of the present study was to test a moderated mediation model for these two distinct ruminative states and to show how personality (i.e. neuroticism and conscientiousness) can alter the mediating effect. The present study is based on 119 surveys from dental students with a time lag of 6 months. Participants filled out questionnaires assessing specific study-relevant performance demands, rumination and personality and a screening measure for psychological health status. Neuroticism was found to moderate the demand-affective rumination association, but conscientiousness did not moderate the demand-problem-solving pondering association. Moderated mediation analysis revealed that affective rumination mediates the impact of demands on psychological health only for individuals low in neuroticism. Findings are discussed regarding potential interventions for dental students to prevent negative psychological health outcomes due to increased work-related demands in the long term.

Wain H, Kneebone II, Cropley M (2011) Attributional intervention for depression in two people with multiple sclerosis (MS): Single case design, Behavioural and Cognitive Psychotherapy 39 (1) pp. 115-121 Cambridge University Press
Background: Depression is common in those with MS. The hopelessness theory of depression, emphasizing the role of attributional style, is supported in this population. Cognitive behaviour therapy (CBT) that can affect attributional style can reduce depression in people who have MS. Aims: The present study aimed to consider whether changing attributional style would reduce depression in two people with MS, thereby supporting the importance of this component of CBT with this population. Method: Two female participants with MS were offered a 5-session intervention designed to alter attributional style. The study followed an ABA design. Attributional style and depressive symptoms were the principal measures considered. Negative life events and MS related stresses were also monitored. Results: The intervention appeared effective for one of the participants, with predicted changes in attributional style and sizeable reductions in depressive symptoms from pre- to post-treatment that were sustained at 3-month follow-up. Improvement was still evident at 6 months, although with some reduction of effect. The intervention was less successful for the other participant who declined further treatment after three sessions. Conclusions: Some support for the hopelessness theory of depression was found, indicating its relevance to CBT interventions for those who have MS and depression.

The objective of this study was to assess long-term job strain impact on morning and evening salivary cortisol secretion. In all 77 white-collar workers (31% women; sample mean age, 42 years at baseline) volunteered to sample morning (immediately after waking up) and evening (10 p.m.) salivary cortisol for 7 consecutive days. By median split on aggregated self-reported isostrain from three consecutive questionnaires distributed in a period of approximately 3.5 years the participants were classified into a high or low long-term isostrain condition. Regardless of strain condition, there was a significant reduction in morning salivary cortisol secretion from the working week to the weekend, whereas evening salivary cortisol secretion showed no significant variation during the week. Although chronic isostrain did not affect the morning saliva cortisol measures, evening cortisol secretion was significantly elevated in the chronic high isostrain group throughout the whole week. The elevated evening cortisol measures associated with chronic high strain are concordant with the findings in other studies on long-term strain.

Locker J, Cropley M (2004) Anxiety, depression and self-esteem in secondary school children - An investigation into the impact of standard assessment tests (SATs) and other important school examinations, School Psychology International 25 (3) pp. 333-345
With the introduction of a new curriculum and increased targets for schools, children are facing increased pressure to succeed in examinations at increasingly earlier ages. It is therefore necessary to emphasize the need for greater awareness of the distress that may be experienced by young children and adolescents as a result and implement provision for early interventions. The aim of this study was to investigate changes occurring in anxiety, affect, depression and self-esteem in secondary school children as they approached important school examinations and to examine variations between schools of differing design and status. There were a total of 520 participants, from four different schools in two school years (year 9, age 13-14 and year 11, age 15-16). Participants completed self-report questionnaires at two time points - firstly during regular term time and the second in the week immediately prior to the examinations. Gender differences were found in the majority of measures with females displaying greater levels of anxiety and negative affect immediately before the examinations, whereas males reported higher positive affect and self-esteem and lower depression and anxiety, even within the week prior to the examinations. Differences between the schools were also found. However, there were no significant differences between the two school years and the two times of testing. A number of trends were identified in relation to both gender differences and the influence of the type of school attended. Females, particularly those attending independent or grammar schools, reported a greater negative mood overall and before the examinations. It is suggested that there is a need for a school-based provision aimed at pro-actively increasing pupils self-esteem and to develop skills for dealing with stressful, situations particularly important examinations.
Zijlstra FR, Cropley M, Rydstedt LW (2014) From recovery to regulation: an attempt to reconceptualize 'recovery from work'., Stress Health 30 (3) pp. 244-252
The concept of 'recovery' (from work) has quickly gained in importance in the occupational health literature. However, we think that the conceptualization of 'recovery' needs some more attention. Although many authors acknowledge that 'recovery' refers to a 'process', the concept is often treated as a static construct. In this paper, we argue that recovery should be conceptualized as a dynamic construct related to changes in psychophysiological state of the person. We refer to two main theories that have provided a theoretical framework for research in this area: Meijman & Mulder's Effort-Recovery (E-R) model and Hobfoll's Conservation of Resources theory. In particular, the E-R model has been seminal in this area and stresses the element of changing psychophysiological states that has been used for reconceptualising 'recovery'. Various biological rhythms influence these changing psychophysiological states, and thus the level of energy (or effort) a person can mobilize or wants to mobilize. A distinction is made between 'physical fatigue' and 'mental fatigue' and its consequences for recovery. The discrepancy between 'actual state' and 'required state' has been suggested as the basis for 'recovery'. This emphasises that recovery is a dynamic and ongoing process, which also included motivational aspects, in particular as far as mental work is concerned. The capacity to maintain self-regulation of one's psychophysiological state is important in this respect. Thus, we propose that 'recovery' is the continuous process of harmonizing the 'actual state' with the state that is 'required' at that moment.
Erskine JA, Ussher M, Cropley M, Elgindi A, Zaman M, Corlett B (2011) Effect of thought suppression on desire to smoke and tobacco withdrawal symptoms., Psychopharmacology (Berl) pp. 1-7 Springer Verlag
RATIONALE: Suppressing smoking thoughts has been shown to result in elevated smoking. However, the effect of suppressing smoking thoughts on desire to smoke and withdrawal symptoms has not been investigated. OBJECTIVES: We examined the effects of suppressing smoking thoughts on the subsequent desire to smoke and on tobacco withdrawal symptoms, relative to groups that were either thinking about anything they wished or actively thinking about smoking. METHODS: A randomised experimental study compared the effects of three manipulations (suppressed smoking thoughts, expressed smoking thoughts and thoughts of anything they wished) on desire and withdrawal immediately after the manipulation and 5 and 10 min after. RESULTS: Suppressing smoking thoughts did not result in elevated subsequent desire to smoke, relative to the other manipulations. Suppressing smoking thoughts resulted in a significant elevation in hunger ratings, relative to the other manipulations, at all measurement times. There were no significant effects for the other withdrawal symptoms. Self-reported greater use of thought suppression in everyday life was significantly associated with greater desire to smoke at baseline and was associated with lower mindfulness scores. CONCLUSIONS: Laboratory-instructed suppression of smoking thoughts is associated with increased reports of hunger but did not lead to increases in other withdrawal symptoms or elevated desire to smoke. Reports of everyday use of thought suppression are associated with elevated desire to smoke at baseline. Further investigations need to assess the effect of suppressing smoking cravings, instead of general smoking thoughts, on desire to smoke and tobacco withdrawal.
Zoupanou Z, Cropley M, Rydstedt LF (2013) Recovery after Work: The Role of Work Beliefs in the Unwinding Process, PlosOne 8 (12) Public Library of Science
According to the Effort-Recovery model, mental or physical detachment from work is an important mechanism of work
related recovery, as delayed recovery has been associated with range of negative health symptoms. In this paper, we
examine whether recovery from work (in the form of mentally disengagement from work) is affected by the concept of
?work ethic?, which refers to beliefs workers hold about their work and leisure and the effects of experiencing interruptions
at work. Two indices of post-work recovery were utilized: problem solving pondering and psychological detachment. The
study was conducted with 310 participants employed from diverse occupational sectors. Main effects of positive and
negative appraisal of work interruption and beliefs were analysed using mediated and moderated regression analysis on
problem-solving pondering and detachment. Weakened belief in wasted time as a partial mediator, reduced problemsolving
pondering post work when interruptions were appraised as positive, and a high evaluation of leisure partially
mediated problem-solving pondering when interruptions were appraised as positive. The results also showed that a high
evaluation of centrality of work and leisure moderated the effect of negative appraisal of work interruption on elevated
problem-solving pondering. Positive appraisal of work interruption was related to problem-solving pondering, and the
strength of this association was further moderated by a strong belief in delay of gratification. In addition, employees?
positive appraisal of work interruption was related to work detachment, and the strength of this association was further
moderated by strong beliefs in hard work and self-reliance. These findings are discussed in terms of their theoretical and
practical implications for employees who are strongly influenced by such work beliefs.
Kneebone II, Hull SL, McGurk R, Cropley M (2012) Reliability and Validity of the Neurorehabilitation Experience Questionnaire for Inpatients, Neurorehabilitation & Neural Repair 26 (7) pp. 834-841 Sage
Background. Patient-centered measures of the inpatient neurorehabilitation experience are needed to assess services. Objective. The objective of this study was to develop a valid and reliable Neurorehabilitation Experience Questionnaire (NREQ) to assess whether neurorehabilitation inpatients experience service elements important to them. Methods. Based on the themes established in prior qualitative research, adopting questions from established inventories and using a literature review, a draft version of the NREQ was generated. Focus groups and interviews were conducted with 9 patients and 26 staff from neurological rehabilitation units to establish face validity. Then, 70 patients were recruited to complete the NREQ to ascertain reliability (internal and test-retest) and concurrent validity. Results. On the basis of the face validity testing, several modifications were made to the draft version of the NREQ. Subsequently, internal reliability (time 1 ± = .76, time 2 ± = .80), test retest reliability (r = 0.70), and concurrent validity (r = 0.32 and r = 0.56) were established for the revised version. Whereas responses were associated with positive mood (r = 0.30), they appeared not to be influenced by negative mood, age, education, length of stay, sex, functional independence, or whether a participant had been a patient on a unit previously. Conclusions. Preliminary validation of the NREQ suggests promise for use with its target population.
Cropley M, Theadom A (2008) Sleep disturbance in fibromyalgia syndrome, Future Rheumatology 3 (6) pp. 533-535 Future medicine
Sleep disturbance is a widely reported and debilitating concomitant of fibromyalgia syndrome (FMS) and plays a pivotal role in exacerbating patients? reporting of symptoms. Bigatti and colleagues report a longitudinal study that examined self-reported sleep, pain, depression and physical functioning in FMS patients at baseline and again at a 12-month follow-up. Their results support previous research in showing that there is a bidirectional correlation between sleep and pain experience. Moreover, the results demonstrated that sleep predicted pain, pain predicted physical functioning, and physical functioning predicted depression, although causality was not actually demonstrated. Nonetheless, this research highlights the prevalence of sleep problems in FMS, and the critical role sleep plays in the quality of life for many patients.
Theadom A, Cropley M, Kantermann T (2015) Daytime napping associated with increased symptom severity in fibromyalgia syndrome, BMC Musculoskeletal Disorders 16 (1)
© 2015 Theadom et al.Background: Previous qualitative research has revealed that people with fibromyalgia use daytime napping as a coping strategy for managing symptoms against clinical advice. Yet there is no evidence to suggest whether daytime napping is beneficial or detrimental for people with fibromyalgia. The purpose of this study was to explore how people use daytime naps and to determine the links between daytime napping and symptom severity in fibromyalgia syndrome. Methods: A community based sample of 1044 adults who had been diagnosed with fibromyalgia syndrome by a clinician completed an online questionnaire. Associations between napping behavior, sleep quality and fibromyalgia symptoms were explored using Spearman correlations, with possible predictors of napping behaviour entered into a logistic regression model. Differences between participants who napped on a daily basis and those who napped less regularly, as well as nap duration were explored. Results: Daytime napping was significantly associated with increased pain, depression, anxiety, fatigue, memory difficulties and sleep problems. Sleep problems and fatigue explained the greatest amount of variance in napping behaviour, p 30 minutes had higher memory difficulties (t = -3.45) and levels of depression (t = -2.50) than those who napped for shorter periods (
Steptoe A, Cropley M, Joekes K (2000) Task demands and the pressures of everyday life: associations between cardiovascular reactivity and work blood pressure and heart rate., Health Psychol 19 (1) pp. 46-54
Associations between cardiovascular stress reactivity and blood pressure and heart rate recorded in everyday life were hypothesized to depend on the stressfulness of the ambulatory monitoring period relative to standardized tasks and on activity levels at the time of measurement. One hundred two female and 60 male school teachers carried out high- and low-demand tasks under standardized conditions and ambulatory monitoring during the working day. Stress ratings during the day were close to those recorded during the low-demand task. Reactions to the low-demand task were significant predictors of ambulatory blood pressure and heart rate independent of baseline, age, gender, and body mass. Associations were more consistent for ambulatory recordings taken when participants were seated than when they were standing and when the ambulatory monitoring day was considered to be as stressful as usual or more stressful than usual, and not less stressful than usual. Laboratory-field associations of cardiovascular activity depend in part on the congruence of stressfulness and physical activity level in the 2 situations.
Steptoe A, Lundwall K, Cropley M (2000) Gender, family structure and cardiovascular activity during the working day and evening., Soc Sci Med 50 (4) pp. 531-539
This study applied psychophysiological methods to the investigation of social roles and well-being, using cardiovascular function over a working day and evening as an index of physiological activation. One hundred and sixty-two full-time school teachers (102 women and 60 men) were assessed using automated ambulatory blood pressure monitoring apparatus, with readings every 20 min through the working day (9.00 am-5.40 pm), and every 30 min in the evening (6.00-10.30 pm). The influence of gender, marital status and parenthood (defined as having at least one child living at home) on blood pressure during the working day and on day-evening differences was examined. There were no differences in blood pressure and heart rate across the working day in relation to marital roles or family structure. However, the decrease in blood pressure between working day and evening was greatest in parents, intermediate in married non-parents, and smallest in single participants without children. Differences in systolic pressure adjusted for age and body mass index averaged -4.46, -1.76 and +0.22 mmHg in the three groups, respectively. A similar pattern was observed for diastolic pressure but not heart rate. We also found that the day-evening fall in systolic pressure was moderated by social support, with the greatest change (mean adjusted difference -6.76 mmHg) in parents who reported high levels of social support. These blood pressure responses did not differ between men and women, and there was no indication of multiple role strain for full-time working mothers. The results were independent of concomitant physical activity, location during measurement, or reported job strain. We argue that findings are consistent with an enhancement model of multiple social roles, and with lower allostatic load on individuals who are working, married and parents. Psychophysiological studies of daily life can complement epidemiological and sociological investigations of social roles and health.

Ellis J, Hampson SE, Cropley M (2002) Sleep hygiene or compensatory sleep practices: An examination of behaviours affecting sleep in older adults, Psychology, Health and Medicine 7 (2) pp. 157-162
The purpose of this research was to examine differences in levels of compensatory (sleep hygiene) sleep practices between older insomniacs and older 'normal sleepers'. Two assumptions were tested. First, that compensatory sleep practices differentiate insomniacs from normal sleepers and second, that these practices relate to the long-term maintenance of chronic insomnia. The participants were 414 older adults who responded to an advertisement in a periodical targeted at older people. They were given a questionnaire to determine their insomnia status, use of compensatory practices and levels of daytime sleepiness. A series of chi-square analyses, t-tests and regression analyses showed both assumptions to be predominantly false. There were however relationships between pre-sleep cognitive activity, irregular sleep patterns, use of medication, and a noisy bedroom environment with insomnia classification. In addition, caffeine use after 2pm was associated with a longer duration of insomnia. The results are discussed in relation to sleep medicine education, interventions for older people in primary care settings, and recent models of insomnia.
Hurn J, Kneebone I, Cropley M (2006) Goal setting as an outcome measure: A systematic review., Clin Rehabil 20 (9) pp. 756-772
BACKGROUND: Goal achievement has been considered to be an important measure of outcome by clinicians working with patients in physical and neurological rehabilitation settings. This systematic review was undertaken to examine the reliability, validity and sensitivity of goal setting and goal attainment scaling approaches when used with working age and older people. AIMS AND OBJECTIVES: To review the reliability, validity and sensitivity of both goal setting and goal attainment scaling when employed as an outcome measure within a physical and neurological working age and older person rehabilitation environment, by examining the research literature covering the 36 years since goal-setting theory was proposed. METHODS: Data sources included a computer-aided literature search of published studies examining the reliability, validity and sensitivity of goal setting/goal attainment scaling, with further references sourced from articles obtained through this process. MAIN FINDINGS: There is strong evidence for the reliability, validity and sensitivity of goal attainment scaling. Empirical support was found for the validity of goal setting but research demonstrating its reliability and sensitivity is limited. CONCLUSIONS: Goal attainment scaling appears to be a sound measure for use in physical rehabilitation settings with working age and older people. Further work needs to be carried out with goal setting to establish its reliability and sensitivity as a measurement tool.

Physical rehabilitation day hospitals are widely used community?based services designed to meet the medical and rehabilitation needs of older people. While there is evidence for the effectiveness of these services, concerns about the shortcomings of how this is measured have led to the recommendation that the achievement of individually tailored goals be used to assess outcomes. This study considered whether such goal achievement demonstrated validity with respect to a standardised measure. The association between goal achievement and change in Nottingham Health Profile?Part 1 (NHP?1) scores was considered for 102 people attending four physical rehabilitation day hospitals. The predicted significant positive relationship between the percentage of goals achieved by participants and NHP?1 scores was not found. This remained evident when functional goals were considered separately to medical goals. Further subsidiary analyses identified a complex relationship between goal achievement and NHP?1 change scores. For those with higher change scores, there was a significant negative association between NHP?1 change and goal achievement; while for those with lower (or negative) change scores, there was a significant positive association. A curve estimate regression confirmed a highly significant quadratic (curvilinear) relationship. Possible reasons for this finding might include the timing and nature of the goals set, the potential complication of some participants having cognitive impairment, as well as the use of the NHP?1 as a comparison measure. At this time it is recommended that goal achievement only be used alongside other measures of day hospital outcome.
Theadom A, Cropley M (2006) Effects of preoperative smoking cessation on the incidence and risk of intraoperative and postoperative complications in adult smokers: a systematic review., Tob Control 15 (5) pp. 352-358
OBJECTIVES: To establish the effect of preoperative smoking cessation on the risk of postoperative complications, and to identify the effect of the timing of preoperative cessation. DATA SOURCES: The Cochrane Library Database, PsycINFO, EMBASE, Medline, and CINAHL databases were searched, using the terms: "smoking", "smoking-cessation", "tobacco-use", "tobacco-abstinence", "cigarett$", "complication$", "postoperative-complication$", "preoperative", "perioperative" and "surg$". Further articles were obtained from reference lists. The search was limited to articles on adults, written in English and published up to November 2005. STUDY SELECTION: Prospective cohort designs exploring the effects of preoperative smoking cessation on postoperative complications were included. Two reviewers independently scanned abstracts of relevant articles to determine eligibility. Lack of agreement was resolved through discussion and consensus. Twelve studies met the inclusion criteria. DATA EXTRACTION: Methodological quality was assessed by both reviewers, exploring validation of smoking status, clear definition of the period of smoking cessation, control for confounding variables and length of follow-up. DATA SYNTHESIS: Only four of the studies specified the exact period of smoking cessation, with six studies specifying the length of the follow-up period. Five studies revealed a lower risk or incidence of postoperative complications in past smokers than current smokers or reported that there was no significant difference between past smokers and non-smokers. CONCLUSIONS: Longer periods of smoking cessation appear to be more effective in reducing the incidence/risk of postoperative complications; there was no increased risk in postoperative complications from short term cessation. An optimal period of preoperative smoking cessation could not be identified from the available evidence.

BACKGROUND: Mental stress has been linked to increased morbidity and mortality in coronary artery disease and to atherosclerosis progression. Experimental studies have suggested that damage to the endothelium may be an important mechanism. METHODS AND RESULTS: Endothelial function was studied in 10 healthy men (aged 50. 4+/-9.6 years) and in 8 non-insulin-dependent diabetic men (aged 52. 0+/-7.2 years). Brachial artery flow-mediated dilation (FMD, endothelium dependent) and response to 50 microg of sublingual glyceryl trinitrate (GTN, endothelium independent) were measured noninvasively by use of high-resolution ultrasound before and after (30, 90, and 240 minutes) a standardized mental stress test. The same protocol without mental stress was repeated on a separate occasion in the healthy men. In healthy subjects, FMD (5.0+/-2.1%) was significantly (P:
Cropley Mark, Zijlstra FRH, Querstret Dawn, Beck S (2016) Is Work-related Rumination Associated with deficits in Executive Functioning?, Frontiers in Psychology 7 1524 Frontiers Media
Work-related rumination, that is, perseverative thinking about work during leisure time, has been associated with a range of negative health and wellbeing issues. The present paper examined the association between work-related rumination and cognitive processes centred around the theoretical construct of executive functioning. Executive functioning is an umbrella term for high level cognitive processes such as planning, working memory, inhibition, mental flexibility; and it underlies how people manage and regulate their goal directed behaviour. Three studies are reported. Study I, reports the results of a cross-sectional study of 240 employees, and demonstrates significant correlations between work-related rumination and three proxy measures of executive functioning: cognitive failures (.33), cognitive flexibility (-.24) and situational awareness at work (-.28). Study II (n = 939), expands on the findings from study 1 and demonstrates that workers reporting medium and high work-related rumination were 2.8 and 5 times, respectively, more likely to report cognitive failures relative to low ruminators. High ruminators also demonstrated greater difficulties with ?lapses of attention? (OR = 4.8), ?lack of focus of attention? (OR = 3.4), and ?absent mindedness? (OR = 4.3). The final study, examined the association between work-related rumination and executive functioning using interview data from 2460 full time workers. Workers were divided into tertiles low, medium and high. The findings showed that high work-related rumination was associated with deficits in starting (OR = 2.3) and finishing projects (OR = 2.4), fidgeting (OR = 1.9), memory (OR = 2.2), pursuing tasks in order (OR = 1.8), and feeling compelled to do things (OR = 2.0). It was argued that work-related rumination may not be related to work demands per se, but appears to be an executive functioning/control issue. Such findings are important for the design and delivery of intervention programmes aimed at helping people to switch off and unwind from work
Steptoe A, Cropley M (2000) Persistent high job demands and reactivity to mental stress predict future ambulatory blood pressure., J Hypertens 18 (5) pp. 581-586
OBJECTIVE: To test the hypothesis that work stress (persistent high job demands over 1 year) in combination with high reactivity to mental stress predict ambulatory blood pressure. DESIGN: Assessment of cardiovascular responses to standardized behavioural tasks, job demands, and ambulatory blood pressure over a working day and evening after 12 months. PARTICIPANTS: We studied 81 school teachers (26 men, 55 women), 36 of whom experienced persistent high job demands over 1 year, while 45 reported lower job demands. METHODS: Participants were divided on the basis of high and low job demands, and high and low systolic pressure reactions to an uncontrollable stress task. Blood pressure and concurrent physical activity were monitored using ambulatory apparatus from 0900 to 2230 h on a working day. RESULTS: Cardiovascular stress reactivity was associated with waist/hip ratio. Systolic and diastolic pressure during the working day were greater in high job demand participants who were stress reactive than in other groups, after adjustment for age, baseline blood pressure, body mass index and negative affectivity. The difference was not accounted for by variations in physical activity. CONCLUSIONS: Cardiovascular stress reactivity and sustained psychosocial stress may act in concert to increase cardiovascular risk in susceptible individuals.

OBJECTIVE: To assess the influence of abdominal obesity and work stress (operationalised as low control over work) on ambulatory blood pressure on a working day and evening. PARTICIPANTS AND METHODS: 156 school teachers (58 men and 98 women) carried out ambulatory blood pressure and heart rate monitoring on a work day and evening. Cardiovascular activity was also measured under baseline conditions on another occasion, when body weight, height, waist and hip circumference were assessed. Perceived control over work was assessed by questionnaire, along with mental health, anger expression and social support. 126 participants repeated the protocol after 12 months. Waist/hip ratio was used as the index of abdominal obesity. RESULTS: Baseline blood pressure was positively associated with waist/hip ratio in men, but ambulatory blood pressure and heart rate were not independently related to waist/hip ratio or job control. However, blood pressure and heart rate recorded during the working day and evening were elevated in men with high waist/hip ratio who experienced low job control, independently of age and body weight. Effects for diastolic blood pressure and heart rate were replicated after 12 months. Body mass index was not related to blood pressure or heart rate during the day or evening after adjustment for age and waist circumference. Low job control was associated with poor psychological well-being, negative mood and lack of social support. CONCLUSIONS: The results are consistent with the hypothesis that abdominal obesity in men is characterised by a tendency towards heightened stress-induced physiological activation, but that this tendency will only be manifest in the presence of appropriate environmental challenges such as chronic work stress.

Aims To examine the acute effects of a guided relaxation routine (body scan) and isometric exercise on desire to smoke and tobacco withdrawal symptoms.

Design Experimental comparison of three conditions.

Participants Forty-eight individuals reporting smoking e10 cigarettes daily.

Intervention Random assignment to one of three interventions delivered via a 10-minute audio: isometric exercise (IE, n = 14), body scanning (BS, n = 18) or a reading about natural history (control group, n = 16). Interventions were delivered twice on the same day: in the laboratory, then in their ?normal? environment.

Measurements Desire to smoke (primary outcome) and withdrawal symptoms were rated at pre-intervention and up to 30 minutes post-intervention.

Findings Controlling for baseline scores, post-intervention desire to smoke and withdrawal symptoms were significantly lower for IE and BS groups, compared with the controls, in both environments. There were no significant differences for IE versus BS. For desire to smoke, controlling for baseline values, ratings in the laboratory were significantly lower for IE and BS versus the control up to 30 minutes post-intervention. In the normal environment, these ratings were significantly lower only up to 5 minutes post-intervention.

Conclusions Brief IE and BS interventions are effective for reducing desire to smoke and withdrawal symptoms in temporarily abstaining smokers. These interventions were found to be more effective in the laboratory than in the smoker's normal environment, but this may be an artefact of there not being a sufficient ?wash-out? period between interventions. These techniques may be beneficial for managing desire to smoke and tobacco withdrawal.

Querstret Dawn, Cropley Mark (2012) Exploring the relationship between work-related rumination, sleep quality and work-related fatigue., Journal of Occupational Health Psychology 17 (3) pp. 341-353 American Psychological Association
Objective: This study examined the association between three conceptualisations of work-related rumination (affective rumination, problem-solving pondering and detachment) with sleep quality and work-related fatigue. It was hypothesised that affective rumination and poor sleep quality would be associated with increased fatigue; and problem-solving pondering, and detachment would be associated with decreased fatigue. The mediating effect of sleep quality on the relationship between work-related rumination and fatigue was also tested. Method: An on-line questionnaire was completed by a heterogeneous sample of 719 adult workers in diverse occupations. Results: The following variables were entered as predictors in a regression model: affective rumination, problem-solving pondering, detachment, and sleep quality. The dependent variables were chronic work-related fatigue (CF) and acute work-related fatigue (AF). Affective rumination was the strongest predictor of increased CF and AF. Problem-solving pondering was a significant predictor of decreased CF and AF. Poor sleep quality was predictive of increased CF and AF. Detachment was significantly negatively predictive for AF. Sleep quality partially mediated the relationship between affective rumination and fatigue; and between problem-solving pondering and fatigue. Conclusions: Work-related affective rumination appears more detrimental to an individual?s ability to recover from work than problem-solving pondering. In the context of identifying mechanisms by which demands at work are translated into ill-health, this appears to be a key finding; and suggests that it is the type of work-related rumination, not rumination per se, that is important.
Griffith J, Steptoe A, Cropley M (1999) An investigation of coping strategies associated with job stress in teachers., The British journal of educational psychology 69
BACKGROUND: School teaching is regarded as a stressful occupation, but the perception of the job as stressful may be influenced by coping responses and social support. AIMS: To assess the associations between teacher stress, psychological coping responses and social support, taking into account the plaintive set engendered by negative affectivity. METHOD: Questionnaire survey of 780 primary and secondary school teachers (53.5% response rate). RESULTS: In stepwise multiple regression, social support at work and the coping responses behavioural disengagement and suppression of competing activities predicted job stress independently of age, gender, class size, occupational grade and negative affectivity. High job stress was associated with low social support at work and greater use of coping by disengagement and suppression of competing activities. CONCLUSIONS: It is suggested that behavioural disengagement and suppression of competing activities are maladaptive responses in a teaching environment and may actually contribute to job stress. Coping and social support not only moderate the impact of stressors on well-being but influence the appraisal of environmental demands as stressful.
Coxon A, Cropley M, Schofield P, Start K, Horsfield C, Quinn T (2016) 'You're never making just one decision': exploring the lived experiences of ambulance Emergency Operations Centre personnel., Emergency medicine journal : EMJ
The aim of this study was to explore the experiences of ambulance dispatch personnel, identifying key stressors and their impact on staff well-being.Qualitative methodology was used. Nine semistructured interviews were conducted with National Health Service (NHS) ambulance Emergency Operations Centre (EOC) dispatch personnel in the UK between July and August 2014. Participants were asked about their experiences of the role, stress experienced and current strategies they use to deal with stress. Transcripts were analysed using an inductive, bottom-up thematic analysis.Three key themes were identified: (1) 'How dispatch is perceived by others', (2) 'What dispatch really involves' and (3) 'Dealing with the stresses of dispatch'. All participants expressed pride in their work, but felt overloaded by the workload and undervalued by others. Several sources of additional stress, not directly related to the execution of their work, were identified, including the need to mentally unwind from work at the end of a shift. Participants were able to identify a number of ways in which they currently manage work-related stress, but they also suggested changes the organisation could put in place in order to reduce stress in the working environment.Building on existing theory on work stress and postwork recovery, it was concluded that EOC dispatch staff require greater support at work, including skills training to promote postshift recovery, in order to reduce the likelihood of sickness absence, and prevent work-related fatigue.
Querstret Dawn, Cropley Mark (2013) Assessing treatments used to reduce rumination and/or worry: A systematic review., Clin Psychol Rev 33 (8) pp. 996-1009
Perseverative cognitions such as rumination and worry are key components of mental illnesses such as depression and anxiety. Given the frequent comorbidity of conditions in which rumination and worry are present, it is possible that they are underpinned by the same cognitive process. Furthermore, rumination and worry appear to be part of a causal chain that can lead to long-term health consequences, including cardiovascular disease and other chronic conditions. It is important therefore to understand what interventions may be useful in reducing their incidence. This systematic review aimed to assess treatments used to reduce worry and/or rumination. As we were interested in understanding the current treatment landscape, we limited our search from 2002 to 2012. Nineteen studies were included in the review and were assessed for methodological quality and treatment integrity. Results suggested that mindfulness-based and cognitive behavioural interventions may be effective in the reduction of both rumination and worry; with both Internet-delivered and face-to-face delivered formats useful. More broadly, it appears that treatments in which participants are encouraged to change their thinking style, or to disengage from emotional response to rumination and/or worry (e.g., through mindful techniques), could be helpful. Implications for treatment and avenues for future research are discussed.

Smoking during pregnancy is widely known to increase health risks to the foetus, and understanding the quitting process during pregnancy is essential in order to realise national government targets. Qualitative studies have been used in order to gain a greater understanding of the quitting process and the objective of this systematic review was to examine and evaluate qualitative studies that have investigated the psychological and social factors around women attempting to quit smoking during pregnancy. Electronic databases and journals were searched with seven articles included in this review. The findings demonstrated that women were aware of the health risks to the foetus associated with smoking; however knowledge of potential health risks was not sufficient to motivate them to quit. Several barriers to quitting were identified which included willpower, role, and meaning of smoking, issues with cessation provision, changes in relationship interactions, understanding of facts, changes in smell and taste and influence of family and friends. A further interesting finding was that cessation service provision by health professionals was viewed negatively by women. It was concluded that there is a shortage of qualitative studies that concentrate on the specific difficulties that pregnant women face when trying to quit smoking.
Daniel J, Cropley M, Ussher M, West R (2004) Acute effects of a short bout of moderate versus light intensity exercise versus inactivity on tobacco withdrawal symptoms in sedentary smokers, Psychopharmacology 174 (3) pp. 320-326
Rationale. A previous study found that a 10-min bout of moderate intensity exercise reduced cigarette withdrawal symptoms and desire to smoke in sedentary smokers but the effect may have been due to participants focusing attention on physical activity rather than the activity itself. Objectives. This study examined the effect of 5 min of moderate intensity exercise and 5 min of light intensity exercise on tobacco withdrawal symptoms amongst sedentary smokers. Methods. Eighty-four smokers attended a laboratory session having abstained from smoking for between 11 and 14 h. Participants were randomly allocated to one of three conditions: (i) light intensity exercise [n=28; 10-20% of heart rate reserve (HRR)]; (ii) moderate intensity exercise (n=28; 40-60% HRR), (iii) a passive control condition (n=28). Both exercise conditions involved 5 min of stationary cycling and participants rated tobacco withdrawal symptoms and cravings immediately before exercise (baseline), during exercise at 2.5 min, immediately following exercise, then after 5 and 10 min of rest. Control participants made the same ratings across an equivalent time period. Results. For moderate intensity exercise compared to light intensity exercise and control there was a significant reduction in strength of desire to smoke, relative to baseline, both during exercise and up to 5 min post-exercise. Relative to baseline, there were also significant reductions in restlessness, stress, tension and poor concentration at 5 and 10 min post-exercise, for moderate intensity exercise compared to light intensity exercise and control. Conclusions. Five minutes of moderate intensity exercise is associated with a short-term reduction in desire to smoke and tobacco withdrawal symptoms. Very brief bouts of exercise may therefore be useful as an aid to smoking cessation.
Ellis J, Cropley M, Hampson S (2001) Insomnia and ageing: Implications for healthcare practice and policy, Quality in Ageing and Older Adults 2 (4) pp. 20-32
Although ageing itself does not lead to insomnia, changes in sleep architecture (the 'typical' physiological progression from wakefulness to deep sleep) and health status create a vulnerability to the development of insomnia, which can be precipitated by a trigger event. This review highlights some of the problems associated with insomnia in older people and offers insights into the possible approaches to stop insomnia from becoming a 'rite of passage'. The main conclusion from this review however, is that sleep research focusing specifically on the ageing population is badly needed, alongside a unified diagnostic system and research structure (Leger, 2000). These findings are also discussed in relation to both healthcare policy and practice. © Copyright - 2001 MCB UP Ltd. All rights reserved.

Diagnosis and treatment of fibromyalgia syndrome (FMS) currently focuses on the experience of widespread pain. However, the symptom experience described by patients with FMS in clinical practice is far more diverse. This study aims identify the most common and severe symptoms in female patients diagnosed with FMS.
From an original sample of 2454 participants free of self-reported psychological distress, 1463 workers completed a 15-month follow-up. Baseline measures included exposure to job demands, decision latitude, social support and need for recovery. Psychological distress was assessed using the General Health Questionnaire at baseline and at follow-up. The findings showed that medium and high exposure to job demands and social support increased the risk of reporting psychological distress at 15-months (relative risk (RR) = 1.65, 1.45). The highest adjusted RR was observed for workers reporting a high need for recovery after work (RR 2.12, 1.90) and this finding was independent of the effects of job demands, decision latitude and social support. Neither decision latitude, nor low back problems increased the risk of reporting future psychological distress, although neck problems (RR = 1.66) and hand/wrist problems (RR = 1.45) did. It was concluded that need for recovery appears to be an important indicator of individual workers who are at risk of developing psychological distress long term. Statement of Relevance: This paper reports the findings of a longitudinal study showing that need for recovery from work was the strongest predictor, relative to psychosocial work characteristics (job demands, decision latitude and social support), and musculoskeletal problems, of psychological distress 15 months later in individuals initially free from distress.

This quasi-experimental longitudinal study assessed the effect of a one-day Cognitive Behaviour Therapy (CBT)-based workshop on work-related rumination, chronic fatigue and sleep quality. We hypothesised that participants who attended the workshop would report lower levels of affective work-related rumination and chronic fatigue and improved sleep quality, at follow-up, six months after workshop completion. Two hundred and twenty seven participants took part in the study, with 102 participants attending a one-day workshop delivered in their place of work. Participants completed an online questionnaire at two time-points, with follow-up occurring 6 months after initial survey completion. Results showed that participants who took part in the CBT workshop reported significantly lower levels of affective rumination (p=.03) and chronic fatigue (p=.003), at follow-up in comparison to individuals who did not attend the workshop; however there were no significant differences between the groups in self-reported sleep quality (p=.06). A combination of more effective recovery both at work and outside of work may explain the reductions in both affective rumination and fatigue over time. This study adds to the recovery from work literature by providing initial support for a one-day CBT-based workshop delivered in the workplace.
Cropley M, Steptoe A, Joekes K (1999) Job strain and psychiatric morbidity., Psychol Med 29 (6) pp. 1411-1416
BACKGROUND: This study examined the association between job strain and psychiatric morbidity using interview-based assessments of mental health. We assessed the prevalence of neurotic disorder in high job strain (high demand, low control) and low job strain (low demand, high control) school teachers, and compared these rates with data from individuals with similar educational qualifications from the National Psychiatric Morbidity Survey of Great Britain. METHODS: One hundred and sixty primary and secondary school teachers were selected from a larger survey on the basis of high or low job strain, and were assessed for psychiatric morbidity using the Revised Clinical Interview Schedule (CIS-R). The prevalence of neurotic symptoms and a total psychiatric morbidity score were calculated. RESULTS: After adjusting for age, gender and occupational grade, the prevalence of psychiatric morbidity was greater in high job strain than low job strain individuals. The prevalence of severe anxiety, worry and fatigue symptoms was significantly greater in the high job strain teachers. In comparison with the British psychiatric morbidity survey, the prevalence of neurotic disorders was greater in the high job strain, but not in low job strain teachers. Individuals in the low job strain group were more likely to report severe anxiety, irritability and fatigue in the week prior to interview, than comparably educated individuals in the national survey. CONCLUSION: Job strain is associated with psychiatric morbidity. The high levels of neurotic psychopathology among teachers is consistent with previous research that has found teaching to be a highly stressful occupation.
Cropley M, Ayers S, Nokes L (2003) People don't exercise because they can't think of reasons to exercise: an examination of causal reasoning within the Transtheoretical Model., Psychol Health Med 8 (4) pp. 409-414
This study compared the accessibility of the pros (advantages) and cons (disadvantages) of exercise in a group of non-exercisers and regular exercisers, using the Transtheoretical Model of behaviour change as a theoretical framework. Pre-contemplators (n
=
18), and maintainers (n
=
25), were asked to generate a list of 'advantages to taking part in exercise' (pro reasons), and a list of 'disadvantages to taking part in exercise' (con reasons). The time to generate their first item was recorded as well as the total number of items generated within 60 s. The results showed that pre-contemplators provided more con reasons relative to pro reasons; and maintainers provided more pro reasons relative to con reasons for exercise. Pre-contemplators were also quicker to provide their first con reason, relative to their first pro reason, but there was no difference in pro and con latencies in the maintainers. It was concluded that one reason pre-contemplation individuals do not participate in regular exercise may be because they cannot think of reasons to exercise.
Steptoe A, Cropley M, Joekes K (1999) Job strain, blood pressure and response to uncontrollable stress., J Hypertens 17 (2) pp. 193-200
OBJECTIVE: The association between cardiovascular disease risk and job strain (high-demand, low-control work) may be mediated by heightened physiological stress responsivity. We hypothesized that high levels of job strain lead to increased cardiovascular responses to uncontrollable but not controllable stressors. Associations between job strain and blood pressure reductions after the working day (unwinding) were also assessed. DESIGN: Assessment of cardiovascular responses to standardized behavioral tasks, and ambulatory monitoring of blood pressure and heart rate during a working day and evening. PARTICIPANTS: We studied 162 school teachers (60 men, 102 women) selected from a larger survey as experiencing high or low job strain. METHODS: Blood pressure, heart rate and electrodermal responses to an externally paced (uncontrollable) task and a self-paced (controllable) task were assessed. Blood pressure was monitored using ambulatory apparatus from 0900 to 2230 h on a working day. RESULTS: The groups of subjects with high and low job strain did not differ in demographic factors, body mass or resting cardiovascular activity. Blood pressure reactions to the uncontrollable task were greater in high than low job-strain groups, but responses to the controllable task were not significantly different between groups. Systolic and diastolic blood pressure did not differ between groups over the working day, but decreased to a greater extent in the evening in subjects with low job strain. CONCLUSIONS: Job strain is associated with a heightened blood pressure response to uncontrollable but not controllable tasks. The failure of subjects with high job strain to show reduced blood pressure in the evening may be a manifestation of chronic allostatic load.
Cropley M, Michailidis E (2016) Exploring Predictors and Consequences of Embitterment in the Workplace, Ergonomics 60 (9) pp. 1197-1206 Taylor & Francis
Research on the feeling of embitterment at work is still in its infancy. The present study investigated the predictors and consequences of the feeling of embitterment at work. It was hypothesised that organisational injustice as well as over-controlling supervision would predict embitterment at work and that embitterment would be associated with work-related rumination. Three hundred and thirty-seven employees completed an online survey. Regression analysis revealed that procedural injustice and over-controlling supervision were significant predictors of embitterment and that embitterment contributed significantly to the prediction of increased affective rumination and reduction in detachment. Mediation analysis indicated that embitterment at work was a significant mechanism through which organisational injustice and over-controlling supervision exerted their effect on affective rumination, which is indicative of insufficient recovery from work. Findings suggest that breaches in organisational justice can generate feelings of embitterment at work, which in turn can interfere with employees? ability to adequately recover from work. Practitioner Summary: The purpose of this study was to investigate predictors and consequences of embitterment in the workplace, by using an online questionnaire. Findings suggest that perceived unfairness, because of structural and organizational aspects, predict feelings of embitterment and that feeling embittered at work can prevent employees from adequately recovering from work.
Golding S, Cropley M (2017) A Systematic Narrative Review of Effects of Community-Based Intervention on Rates of Organ Donor Registration, Progress in Transplantation 27 (3) pp. 295-308 Sage
Background: The demand for organ donation is increasing worldwide. One possible way of increasing the pool of potential posthumous donors is to encourage more members of the general public to join an organ donor registry. Objective: A systematic review was conducted to investigate the effectiveness of psychological interventions designed to increase the number of individuals in the community who register as organ donors. Methods: PsycINFO and PubMed databases were searched. No date limits were set. Randomized and non-randomized controlled trials exploring the effects of community-based interventions on organ donor registration rates were included. Methodological quality was assessed using the ?Quality Assessment Tool for Quantitative Studies?. Results: 24 studies met the inclusion criteria; 19 studies found a positive intervention effect on registration. Only eight studies were assessed as having reasonable methodological robustness. A narrative synthesis was conducted. Factors influencing registration rates include providing an immediate registration opportunity and using brief interventions to challenge misconceptions and concerns about organ donation. Discussion: Community based interventions can be effective at increasing organ donor registrations amongst the general public. Factors that may increase effectiveness include brief interventions to address concerns, and providing an immediate registration opportunity. Particular consideration should be paid to the fidelity of intervention delivery.
The aim of this thesis was to investigate the effects of the guided body scan on cigarette cravings and nicotine withdrawal symptoms in temporarily abstinent smokers. In light of evidence that a combination of pharmacotherapy and behavioural support can result in even greater success rates than either strategy alone (Stead & Lancaster, 2012), study one was the first randomised placebo-controlled trial to examine how the body scan interacts with traditional nicotine replacement therapy. Unfortunately, the magnitude of an anti-placebo effect meant that neither the nicotine nor placebo patches had an effect on ratings of withdrawal symptoms and tobacco cravings. The results did however show that the body scan produced significant post intervention reductions relative to baseline, whilst unexpectedly finding that the control audio also yielded similar levels of efficacy. This cast doubt on the theory that the body scan reduces cravings and withdrawal symptoms via the promotion of non-judgemental acceptance of thoughts and feelings, although the idea that both audio interventions acted as a form of cognitive distraction seemed more plausible. The secondary aim was therefore to explore whether cognitive distraction is a mechanism underlying the efficacy of the body scan, with study three comparing a guided body scan to two distraction tasks. The results indicated that relative to baseline, all three interventions produced reductions in withdrawal symptoms up to 10 minutes post task, however the body scan out performed the two distraction tasks in reducing the desire to smoke. This implies that whilst the processes associated with cigarette withdrawal might be vulnerable to disruption via cognitive distraction, the desire for a cigarette is less susceptible. Instead, the body scan may provide additional benefits via the moderation of negative affect or a relaxation response.
Schlachter Svenja, McDowall A, Cropley Mark, Inceoglu Ilke (2017) Voluntary Work-Related Technology Use during Non-Work Time: A Narrative Synthesis of Empirical Research and Research Agenda, International Journal of Management Reviews 20 (4) pp. 825-846 Wiley
The internet and mobilisation of information and communication technologies (ICTs) have made non-manual work increasingly portable and remotely accessible. As a result, a considerable number of employees use their ICTs to engage in work-related tasks during designated non-work time, even without contractual obligation. However, existing research on such voluntary work-related ICT use remains fragmented and spread across disciplines. We conducted a narrative review of 56 studies to identify themes in existing research, synthesise the evidence base, as well as identify gaps in our understanding. We identify five themes, namely: (1) Social-normative organisational context, (2) Job-related characteristics and work processes, (3) Person characteristics, (4) Designated non-work time and well-being, and (5) Empowerment/Enslavement Paradox. A conceptual model of voluntary ICT use is developed by integrating the identified themes with existing organisational research, outlining the relationships between the identified themes and voluntary ICT use. In the discussion, we emphasise the need for more conceptual clarity on voluntary ICT use and related constructs, and for the integration of different disciplines and methodological approaches to advance knowledge in the field. We further identify person-centred research as critical future avenue to explore different ICT user types. Additionally, more research into the mechanisms and moderating influences regarding voluntary ICT use and its outcomes is considered advisable to advance our knowledge on the Empowerment/Enslavement Paradox and its potential resolution. We conclude with preliminary implications to inform practice, addressing the need for employers to provide control over voluntary ICT use, as well as employees enacting this control.

Background and purpose. Evidence suggests that exercise decreases nicotine withdrawal symptoms in humans; however, the mechanisms mediating this effect are unclear. We investigate, in a mouse model, the effect of exercise intensity during chronic nicotine exposure on nicotine withdrawal severity, binding of ±4²2*, ±7 nicotinic acetylcholine (nAChR), ¼-opioid (¼ receptors) and D2 dopamine receptors, and on brain-derived neurotrophic factor (BDNF) and plasma corticosterone levels.

Experimental approach. Male C57Bl/6J mice treated with nicotine (minipump, 24 mg kg-1 day-1) or saline for 14 days underwent one of three concurrent exercise regimes: 24, 2 or 0 hrs day-1 voluntary wheel running. Mecamylamine-precipitated withdrawal symptoms were assessed on day 14. Quantitative autoradiography of ±4²2*, ±7 nAChRs, ¼ receptors and D2 receptor binding was performed in brain sections of these mice. Plasma corticosterone and brain BDNF levels were also measured.

Key results. Nicotine-treated mice undertaking 2 or 24 hrs day-1 wheel running displayed a significant reduction of withdrawal symptom severity compared with the sedentary group. Wheel-running induced a significant upregulation of ±7 nAChR binding in the CA2/3 area of the hippocampus of nicotine-treated mice. Neither exercise nor nicotine treatment affected ¼ or D2 receptor binding or BDNF levels. Nicotine withdrawal increased plasma corticosterone levels and ±4²2* nAChR binding, irrespective of exercise regimen.

Conclusions and implications. We demonstrate for the first time a profound effect of exercise on ±7 nAChRs of nicotine-dependent animals, irrespective of exercise intensity. These findings shed light onto the mechanism underlining the protective effect of exercise in the development of nicotine dependence.

KEY POINTS

" In clinical settings, rumination can be defined as a maladaptive and repetitive thinking process that focuses on symptoms, causes and consequences of one?s illness
" A cross-sectional study was designed to investigate the incidence of rumination and its determinants in two samples of 98 breast and lung cancer patients
" Results showed that rumination related to cancer was evident in almost half of the participants and was significantly correlated with general rumination
" Rumination was also negatively correlated with social support and quality of sleep and positively correlated with the perception of individual responsibility in having cancer
" The high prevalence of rumination in cancer patients suggests the need for future longitudinal studies to analyze its long-term effects on illness prognosis, patient quality of life, and psychological wellbeing, as well as the need to develop specific interventions to help reduce its impact on illness management in patients

Background. The study objective was to investigate and synthesize available evidence
relating to the psychological health of Emergency Dispatch Centre (EDC) operatives,
and to identify key stressors experienced by EDC operatives.

Methods. Eight electronic databases (Embase, PubMed, Medline, CINAHL, PsycInfo,
PsycArticles, The Psychology and Behavioural Sciences Collection, and Google Scholar)
were searched. All study designs were included, and no date limits were set. Studies
were included if they were published in English, and explored the psychological health
of any EDC operatives, across fire, police, and emergency medical services. Studies were
excluded if they related solely to other emergency workers, such as police officers or
paramedics. Methodological quality of included studies was assessed using checklists
adapted from the Critical Appraisal Skills Programme. A narrative synthesis was
conducted, using thematic analysis.

Results. A total of 16 articles were included in the review. Two overarching themes were
identified during the narrative synthesis: `Organisational and Operational Factors' and
`Interactions with Others'. Stressors identified included being exposed to traumatic
calls, lacking control over high workload, and working in under-resourced and pres-
sured environments. Lack of support from management and providing an emotionally
demanding service were additional sources of stress. Peer support and social support
from friends and family were helpful in managing work-related stress.

Discussion. EDC operatives experience stress as a result of their work, which appears to
be related to negative psychological health outcomes. Future research should explore
the long-term effects of this stress, and the potential for workplace interventions to
alleviate the negative impacts on psychological health.

Embitterment has been described as the emotion generated in the aftermath of an event experienced as unjust and unfair. Although embitterment is most commonly presented in the work context, research on workplace embitterment has remained scarce due to the fact that the concept of embitterment is rather new. This thesis aimed to shed some light on the prevalence of this emotion, its developmental context, outcomes and ways of treating it.
Three studies were carried out. In study 1, results from a cross-sectional study (N = 337) showed that procedural injustice and over-controlling supervision were significant predictors of workplace embitterment. Findings also showed that embitterment contributes significantly to the prediction of increased affective rumination and reduction in detachment, which are indicative of insufficient recovery from work. In study 2, results from a six month longitudinal study design (N = 169) showed that distributive injustice and informational injustice as well as over controlling supervision in Time 1 significantly predicted workplace embitterment six months later. Results also suggested that workplace embitterment in Time 1 significantly predicted reduced levels of work engagement and job satisfaction six months later. In study 3, results from a randomized control trial using participants who were embittered in their workplace showed that participants who completed an expressive writing exercise (N = 23) did not show significantly lower levels of embitterment, affective rumination, higher levels of detachment, work engagement, job satisfaction, either improved sleep quality, compared to participants who completed the factual writing (N = 21).
In summary, results from this thesis suggests that breaches in organisational justice, can trigger feelings of workplace embitterment which can impact negatively employees? ability to psychologically unwind from work, as well as their work engagement and job satisfaction levels. The unfolding of further features of workplace embitterment and the development of interventions to improve this feeling seems a worthwhile future endeavor.
Golding S, Gatersleben B, Cropley M (2018) An Experimental Exploration of the Effects of Exposure to Images of Nature on Rumination, International Journal of Environmental Research and Public Health 15 (2) MDPI
Exposure to natural environments has been shown to have beneficial effects on mood. Rumination is a thinking style associated with negative mood, and sometimes depression, and is characterized by repetitive, intrusive thoughts, often with a negative emotional element. This study investigated whether exposure to nature, operationalized using photographs presented as a slideshow, could aid reduction in levels of state rumination. An experimental, within-between (Time x Condition) participant design was used; participants (n = 58) undertook a presentation task designed to induce rumination and influence mood. Participants were then randomly allocated to either: watch a slideshow of a natural environment, watch a slideshow of an urban environment, or wait patiently with no distractions. Data were collected at baseline, after the presentation, and after the slideshow. Environmental exposure had no effect on levels of rumination or negative mood, but did have a significant effect on levels of positive mood, ?being away?, and ?fascination?. Positive mood declined in those who saw the urban slideshow, but remained the same in those who saw the nature slideshow, whilst levels of being away and fascination were highest in those who saw the nature slideshow. This study extends previous restorative environment research by exploring the effects of nature on rumination.
Twenty-first century workplaces have changed considerably, not least through technological developments which enable employees to engage in voluntary information and communication technology (ICT) use for work-related purposes during non-work time without contractual obligation. The overall aim of this thesis was to examine the concept of voluntary ICT use, its antecedents and consequences for employee recovery and well-being in order to develop an evidence-based conceptual model as a theoretical basis to advance future research in this area.

One systematic review and three empirical studies were conducted. In the systematic review, literature on voluntary ICT use (i.e., 73 studies) was systematically identified and synthesised in order to establish the existing evidence base. This resulted in an operational definition and conceptual model of voluntary ICT use which provided a framework for the subsequent empirical studies. In Study 1, a two-part cross-sectional questionnaire study, antecedents of voluntary ICT use at the social-normative organisational level (Study 1a, N = 157) and at the individual level (Study 1b, N = 165) were examined. Study 1 identified the supervisor?s availability expectations and colleagues? ICT use during non-work time as the most influential antecedents at the social-normative organisational level, and lack of psychological detachment at the individual level. In both parts, autonomous ICT use motivation explained a considerable amount of variance in voluntary ICT use. In Study 2, a daily diary study over five consecutive workdays (nbetween = 197, nwithin = 823), voluntary ICT use during workday evenings was found to negatively affect recovery and affective well-being reported at bedtime by impeding psychological detachment; these indirect effects were also observed regarding well-being the following morning, but were less pronounced. Study 3 comprised an experimental field study which evaluated the effectiveness of a three-week intervention that encourages an active boundary management in relation to voluntary ICT use. It was found that participants reported a short-term reduction in voluntary ICT use at the weekend, as well as delayed increases in ICT-related self-control and decreases in need for recovery in comparison to a waitlist control group (T2; N = 55).

In summary, this thesis contributes to the establishment of voluntary ICT use as a concept and to existing theories of boundary management and work-related recovery by highlighting their interrelations with voluntary ICT use. Drawing on the findings from the empirical studies, evidence-based, practical guidance is provided, encouraging a more conscious, purposeful management of voluntary ICT use. Directions for future research are suggested in relation to the extension of the conceptual model, the added value of person-centred research and the practical implementation of lessons learnt in a holistic way, aiming to progress in informing policy-makers, employers and employees effectively.

Cropley M, Plans D, Morelli D, Sütterlin S, Inceoglu I, Thomas G, Chu C (2017) The Association between Work-Related Rumination and Heart Rate Variability: A Field Study, Frontiers in Human Neuroscience 11 27 Frontiers Media
The objective of this study was to examine the association between perseverative cognition in the form of work-related rumination, and heart rate variability (HRV). We tested the hypothesis that high ruminators would show lower vagally mediated HRV relative to low ruminators during their leisure time. Individuals were classified as being low (n = 17) or high ruminators (n = 19), using the affective scale on the work-related rumination measure. HRV was assessed using a wrist sensor band (Microsoft Band 2). HRV was sampled between 8 pm and 10 pm over three workday evenings (Monday to Wednesday) while individuals carried out their normal evening routines. Compared to the low ruminators, high affective ruminators demonstrated lower HRV in the form of root mean square successive differences (RMSSDs), relative to the low ruminators, indicating lower parasympathetic activity. There was no significant difference in heart rate, or activity levels between the two groups during the recording periods. The current findings of this study may have implications for the design and delivery of interventions to help individuals unwind post work and to manage stress more effectively. Limitations and implications for future research are discussed.
Michailidis Evie, Cropley Mark (2018) Investigating the predictors of workplace embitterment using a longitudinal design, Occupational Medicine 68 (8) kqy121 pp. 523-529 Oxford University Press
Background:

Embitterment has been described as the emotion generated by an event experienced as unjust. Although clinicians working in occupational health services readily recognise features of embitterment in organisations, little attention has been given to workplace embitterment. Research is warranted to identify predictors and features of employees? embitterment.

Aims:

To explore the predictors and the chronicity of workplace embitterment over six months.

Methods:

A longitudinal study investigating the chronicity of workplace embitterment and its antecedents among employees from various occupations. Data were collected by online questionnaires including measures of workplace embitterment, organisational justice and employees? perceptions of supervisory control.

Results:

The survey was completed by 352 employees at Time 1, and 169 at Time 2. The final sample (assessed at two time points) was 147 employees. The feeling of workplace embitterment appeared to be very stable during the six-month period. Hierarchical regression analysis revealed that perceptions of distributive injustice, informational injustice, and employees? perceptions on supervisory over-control in Time 1 significantly predicted embitterment in Time 2. Only the relationship between employees? perceptions of supervisory control and embitterment remained significant after controlling for baseline levels of embitterment.

Conclusion:

This study provides evidence for the negative impact perceived organisational injustice can have on employees? experience of workplace embitterment. Results indicate that employees who perceive their supervisor as being over controlling are more likely to suffer from workplace embitterment. The finding that workplace embitterment is stable during a six-month period highlights the need for effective interventions in ameliorating and preventing workplace embitterment.

Mindfulness interventions have been shown to be effective for health and wellbeing, and delivering mindfulness programmes online may increase accessibility and reduce waiting times and associated costs; however, research assessing the effectiveness of online interventions is lacking. We sought to: (1) assess the effects of an online mindfulness intervention on perceived stress, depression and anxiety; (2) assess different facets of mindfulness (i.e. acting with awareness, describing, non-judging and non-reacting) as mechanisms of change and (3) assess whether the effect of the intervention was maintained over time. The sample was comprised of 118 adults (female, n = 95) drawn from the general population. Using a randomised waitlist control design, participants were randomised to either an intervention (INT) or waitlist control (WLC) group. Participants completed the online intervention, with the WLC group starting after a 6-week waitlist period. Participants completed measures of depression (PHQ-9), anxiety (GAD-7) and perceived stress (PSS-10) at baseline, post-treatment, 3- and 6-month follow-up. Participants who completed the mindfulness intervention (n = 60) reported significantly lower levels of perceived stress (d = ? 1.25 [? 1.64, ? 0.85]), anxiety (d = ? 1.09 [? 1.47, ? 0.98]) and depression (d = ? 1.06 [? 1.44, ? 0.67]), when compared with waitlist control participants (n = 58), and these effects were maintained at follow-up. The effect of the intervention was primarily explained by increased levels of non-judging. This study provides support for online mindfulness interventions and furthers our understanding with regards to how mindfulness interventions exert their positive effects.

A randomised waitlist control trial., Journal of Occupational Health Psychology 22 (2) pp. 153-169 American Psychological Association
This study aimed to extend our theoretical understanding of how mindfulness-based interventions exert their positive influence on measures of occupational health. Employing a randomised waitlist control study design, we sought to: (1) assess an Internet-based instructor-led mindfulness intervention for its effect on key factors associated with ?recovery from work?, specifically, work-related rumination, fatigue and sleep quality; (2) assess different facets of mindfulness (acting with awareness, describing, non-judging, and non-reacting) as mechanisms of change; and (3) assess whether the effect of the intervention was maintained over time by following up our participants after three and six months. Participants who completed the mindfulness intervention (N=60) reported significantly lower levels of work-related rumination and fatigue, and significantly higher levels of sleep quality, when compared with waitlist control participants (N=58). Effects of the intervention were maintained at three and six month follow-up with medium to large effect sizes. The effect of the intervention was primarily explained by increased levels of only one facet of mindfulness (acting with awareness). This study provides support for online mindfulness interventions to aid recovery from work and furthers our understanding with regards to how mindfulness interventions exert their positive effects.

Major Depressive Disorder (MDD) is associated with hypothalamic-pituitary-adrenal axis (HPA) dysregulation and altered cortisol awakening response (CAR), a non-invasive biomarker for HPA axis reactivity. We theorized that the CAR resembles the accumulated effects of depression over time, and may therefore predict depressive symptom severity once patients return home following inpatient treatment. Two studies are reported. In Study 1 (n/=/101; 57% female), the CAR was measured at intake and self-ratings of depression severity was assessed six weeks following discharge. Study 2 (n/=/127; 58% female) was a replication and extension of Study 1 where a follow-up assessment of self-rated depression severity was added at six months following discharge. In Study 1 the CAR at intake showed a tendency towards a negative association with self-reported depression six weeks after discharge. Study 2 extended this finding within a more severely depressed, larger sample, where a blunted CAR predicted self-reported depressive severity six weeks and six month following discharge. These findings suggest that a blunted CAR can predict mood deterioration post treatment in inpatients diagnosed with severe MDD.
Plans David, Morelli Davide, Sütterlin Stefan, Ollis Lucie, Derbyshire Georgia, Cropley Mark (2019) Use of a Biofeedback Breathing App to Augment Poststress Physiological Recovery: Randomized Pilot Study, JMIR Formative Research 3 (1) JMIR Publications

Background: The speed of physiological recovery from stress may be a marker for cardiovascular disease risk. Stress management programs that incorporate guided breathing have been shown to moderate the stress response and augment recovery.

Objective: The aim of this study was to examine the effectiveness of an app-based brief relaxation intervention (BioBase) for facilitating physiological recovery in individuals exposed to a brief psychological stressor.

Methods: A total of 75 participants (44 women) completed a stressor speech task and were randomly assigned to one of three conditions: control, rumination, or an app-based relaxation breathing (BioBase) conditions. Heart rate variability (HRV) was assessed as a measure of autonomic function at baseline (6 min), during stress (6 min), and during recovery (6 min).

Results: There was a significant increase in subjective stress following stress exposure, but the ratings returned to baseline after recovery in all three groups. In addition, there was a significant decrease in vagally mediated HRV in the poststress period. During recovery, the root mean square of successive differences (PÂ.001), the percentage of successive interbeat (RR) intervals that differ by Ã50 ms (pNN50; PÂ.001), and high-frequency (PÂ.02) HRV were significantly higher in the BioBase breathing condition than the rumination and control conditions. There was no difference in HRV values between the rumination and control conditions during recovery.

Conclusions: App-based relaxed breathing interventions could be effective in reducing cardiovascular disease risk. These results provide additional utility of biofeedback breathing in augmenting physiological recovery from psychological stress.

Michailidis Evie, Cropley Mark (2019) Testing the benefits of expressive writing for workplace embitterment: a randomized control trial, European Journal of Work and Organizational Psychology 28 (3) pp. pp 315-328
Clinicians working in occupational health services often recognise features of embitterment in organisations, however, research on interventions for embitterment are scarce. The present study aimed to assess the effectiveness of an expressive writing intervention on working adults who experience workplace embitterment. Employing a randomised control trial we sought to test an expressive writing intervention for its effects on reducing embitterment, work-related rumination and sleep quality and assess whether the effect of the intervention was maintained over time by following up participants after one and three months. Findings partially supported our hypothesis as results showed that participants who completed the expressive writing intervention (N = 23) did not show significantly lower levels of embitterment, affective rumination, higher levels of detachment, either improved sleep quality, compared to participants who completed the factual writing (N = 21), when baseline values were controlled for. However, when looking at the mean scores embitterment and affective rumination levels diminished, detachment levels increased and sleep quality improved throughout the course of the intervention for both groups. Given the stability of embitterment and as findings from this study indicate embitterment diminished after a writing exercise irrespective of emotional disclosure taking place or not, further research and investigation is warranted.
The impact of gynaecological cancers is multifaceted. Whilst many women enjoy good quality of life post treatment, a significant minority continue to experience poor emotional and physical wellbeing. Ineffective management of these consequences in follow-up care leads to lack of support and information contributing to ongoing unmet needs. This thesis explores the experience of women in the survivorship phase and efficacy of a psychosocial intervention to improve quality of life. Six studies were carried out. Study 1 (N=150), a Service Evaluation using the Holistic Needs Assessment (HNA), indicates women diagnosed with gynaecological cancers have heterogeneous concerns across the cancer trajectory, with varying levels of distress. Study 2, a systematic review of psychosocial interventions demonstrates promising results for use in women with gynaecological cancers, with most effective studies using relaxation or counselling/CBT techniques. Study 3 (N=49), a feasibility study, showed health and wellbeing events (HWE) were well received by patients and women intended to make behavioural changes post intervention. In study 4 (N=7), a focus group explored the experience of attending a HWE and, using thematic analysis, four themes emerged: 1) Sharing and validation of experience, (2) Individual and specific information, (3) Adjusting to a new self, (4) Behaviour change. Study 5 (N=216), a quasi-experimental design study on HWE?s indicated short-term improvements in social functioning, increases in fruit consumption, and trend for improvement in physical activity, yet a reduction in perceived social support and increase in depression; whilst long-term improvements in emotional/social/cognitive functioning, fatigue and financial difficulties were seen, increases in vegetable consumption, and the intervention may protect against depression and decreased resilience over time. In study 6 (N=12) focus group data explored patients? experience of attending the HWE and thematic analysis revealed four themes: (1) Support; (2) Timing; (3) Reticence; (4) Understanding disease and the cancer experience. In summary, the results from this thesis suggest benefits in the use of health and wellbeing event interventions in a gynaecological cancer sample. However, further research is required to identify key intervention components suitable in this sample. Additional strategies may need to be considered to meet the unmet needs and ongoing physical and psychological sequelae these women face.
