Psychosocial work environment and stress-related disorders, a systematic review

Workplace interventions for common mental disorders: a systematic meta-review

Depression and anxiety disorders are the leading cause of sickness absence and long-term work incapacity in most developed countries. The present study aimed to carry out a systematic meta-review examining the effectiveness of workplace mental health interventions, defined as any intervention that a workplace may either initiate or facilitate that aims to prevent, treat or rehabilitate a worker with a diagnosis of depression, anxiety or both. Relevant reviews were identified via a detailed systematic search of academic and grey literature databases. All articles were subjected to a rigorous quality appraisal using the AMSTAR assessment. Of the 5179 articles identified, 140 studies met the inclusion criteria, of which 20 were deemed to be of moderate or high quality. Together, these reviews analysed 481 primary research studies. Moderate evidence was identified for two primary prevention interventions; enhancing employee control and promoting physical activity. Stronger evidence was found for CBT-based stress management although less evidence was found for other secondary prevention interventions, such as counselling. Strong evidence was also found against the routine use of debriefing following trauma. Tertiary interventions with a specific focus on work, such as exposure therapy and CBT-based and problem-focused return-to-work programmes, had a strong evidence base for improving symptomology and a moderate evidence base for improving occupational outcomes. Overall, these findings demonstrate there are empirically supported interventions that workplaces can utilize to aid in the prevention of common mental illness as well as facilitating the recovery of employees diagnosed with depression and/or anxiety.

Quality care, public perception and quick-fix service management: a Delphi study on stressors of hospital doctors in Ireland

OBJECTIVES

To identify and rank the most significant workplace stressors to which consultants and trainees are exposed within the publicly funded health sector in Ireland.

DESIGN

Following a preliminary semistructured telephone interview, a Delphi technique with 3 rounds of reiterative questionnaires was used to obtain consensus. Conducted in Spring 2014, doctors were purposively selected by their college faculty or specialty training body.

SETTING

Consultants and higher specialist trainees who were engaged at a collegiate level with their faculty or professional training body. All were employed in the Irish publicly funded health sector by the Health Services Executive.

PARTICIPANTS

49 doctors: 30 consultants (13 male, 17 female) and 19 trainees (7 male, 12 female). Consultants and trainees were from a wide range of hospital specialties including anaesthetics, radiology and psychiatry.

RESULTS

Consultants are most concerned with the quality of healthcare management and its impact on service. They are also concerned about the quality of care they provide. They feel undervalued within the negative sociocultural environment that they work. Trainees also feel undervalued with an uncertain future and they also perceive their sociocultural environment as negative. They echo concerns regarding the quality of care they provide. They struggle with the interface between career demands and personal life.

CONCLUSIONS

This Delphi study sought to explore the working life of doctors in Irish hospitals at a time when resources are scarce. It identified both common and distinct concerns regarding sources of stress for 2 groups of doctors. Its identification of key stressors should guide managers and clinicians towards solutions for improving the quality of patient care and the health of care providers.

Work Stress and Metabolic Syndrome in Police Officers. A Prospective Study

OBJECTIVE

The aim of this longitudinal study was to evaluate the association between occupational stress and metabolic syndrome (MetS) in a rapid response police unit.

METHOD

Work-related stress was continuously monitored during the 5-year period with both the Demand-Control-Support (DCS) and the Effort-Reward Imbalance (ERI) models. Blood pressure, body mass index (BMI), waist circumference, triglycerides, HDL-cholesterol, and fasting blood glucose were measured at baseline in January 2009, and in January 2014. 234 out of 290 police officers (81%) completed the follow-up.

RESULTS

The majority of police officers had high stress levels. At follow-up, police officers in the highest quartile of stress had significantly higher mean levels of triglycerides, and lower levels of HDL-cholesterol than their colleagues in the lowest quartile. Police officers with high stress had an increased adjusted risk of developing MetS (aOR = 2.68; CI95% = 1.08-6.70), and hypertriglyceridemia (aOR = 7.86; CI95 = 1.29-48.04). Demand and Effort were significant predictors of MetS.

CONCLUSION

Our study supports the hypothesis that work-related stress induces MetS, particularly through its effects on blood lipids. Future longitudinal studies with continuous monitoring of stress levels will definitively confirm this hypothesis.

Psychological job strain, social support at work and daytime secretion of dehydroepiandrosterone (DHEA) in healthy female employees: cross-sectional analyses

Evidence is limited concerning the influences of high psychological job strain and low social support at work on daytime secretion of dehydroepiandrosterone (DHEA), which demonstrates anti-cortisol effects. We carried out a cross-sectional study to examine the associations of job strain and social support with daytime secretion amounts of DHEA and cortisol and daytime variation of the cortisol-to-DHEA ratio (C/D ratio) in healthy female workers. Study subjects comprised 115 healthy female nursery school teachers. Area under the curve with respect to ground (AUCG) of salivary DHEA, cortisol and C/D ratio was calculated for estimation of daytime secretion and variation. Social support scores were negatively associated with daytime DHEA secretion (standardized partial regression coefficient = -0.343, P < 0.001 by multiple linear regression analysis). This association remained significant when daytime cortisol secretion was additionally adjusted. Social support was not associated with daytime variation of the C/D ratio. Significant association between social support and daytime cortisol secretion was not confirmed. Job strain was not associated with DHEA, cortisol or the C/D ratio. In summary, we found that daytime DHEA secretion was increased in healthy workers with low social support, perhaps independent of daytime cortisol secretion.

Suicide Mortality Across Broad Occupational Groups in Greece: A Descriptive Study

Background

Several studies have investigated the relationship between specific occupations and suicide mortality, as suicide rates differ by profession. The aim of this study was to investigate suicide mortality ratios across broad occupational groups in Greece for both sexes in the period 2000–2009.

Methods

Data of suicide deaths were retrieved from the Hellenic Statistical Authority and comparative mortality ratios were calculated. Occupational classification was based on the International Classification of Occupations (ISCO-88) and the coding for Intentional self-harm (X60–X84) was based on the international classification of diseases (ICD-10).

Results

Male dominant occupations, mainly armed forces, skilled farmers and elementary workers, and female high-skilled occupations were seen as high risk groups for suicide in a period of 10 years. The age-productive group of 30–39 years in Greek male elementary workers and the 50–59 age-productive group of Greek professional women proved to have the most elevated number of suicide deaths.

Conclusion

Further research is needed into the work-related stressors of occupations with high suicide mortality risk and focused suicide prevention strategies should be applied within vulnerable working age populations.

Concepts of social epidemiology in health services research

Background

Social epidemiologists aim to identify social characteristics that affect the pattern of disease and health distribution in a society and to understand its mechanisms. Some important concepts of social epidemiology are: social inequalities, social relationships, social capital, and work stress.

Discussion

Concepts used in social epidemiology can make a useful contribution to health services research because the underlying social factors do not only influence health but are also related to health care. Social inequality indicators like education or income have an impact on access to health care as well as on utilization and quality of health care. Social relationships influence adherence to medical treatment, help-seeking behavior, utilization of health services, and outcomes. Social capital in health care organizations is an important factor for the delivery of high-quality coordinated care. Job stress is highly prevalent among health care providers and can not only affect their health but also their performance.

Summary

The theoretical considerations behind factors like social inequalities, social relationships, social capital and work stress can enrich health services research because theory helps to specify the research question, to clarify methodological issues, to understand how social factors are related to health care, and to develop and implement interventions.

Recovery of Work-Related Stress: Complaint Reduction and Work-Resumption are Relatively Independent Processes

PURPOSE

The process of recovery from work-related stress, consisting of complaint reduction and work-resumption, is not yet fully understood. The aim of this study was to investigate predictors of complaint reduction and work-resumption, as well as testing complaint reduction as a mediator in the association between predictors and work-resumption.

METHODS

Seventy-one patients on sickness-leave because of work-related stress complaints were followed over a period of 13 months. Predictors comprised personal (demographics, coping, cognitions), work-related (job-characteristics, social support), and illness-related (complaint duration, absence duration) variables. Dependent variables were distress complaints, burnout complaints, and work-resumption.

RESULTS

Complaints reduced considerably over time to borderline clinical levels and work-resumption increased to 68% at 13 months. Predictors of stronger reduction of distress complaints were male gender, less working hours, less decision authority, more co-worker support, and shorter absence duration. Predictors of stronger reduction of burnout complaints were male gender, lower age, high education, less avoidant coping, less decision authority, more job security, and more co-worker support. Predictors of work-resumption were lower age and stronger reduction of burnout complaints. No indication for a mediating role of burnout complaints between the predictor age and work-resumption was found.

CONCLUSIONS

Complaint reduction and work-resumption are relatively independent processes. Symptom reduction is influenced by individual and work-related characteristics, which holds promise for a multidisciplinary treatment approach for work-related stress.

Early and Late Return to Work After Sick Leave: Predictors in a Cohort of Sick-Listed Individuals with Common Mental Disorders

OBJECTIVES

The study aims to identify individual and workplace factors associated with early return to work (RTW)-defined as within 3 months-and factors associated with later RTW-between 3 and 12 months after being sick-listed-in a cohort of newly sick-listed individuals with common mental disorders.

METHODS

In a prospective cohort study, a cross-sectional analysis was performed on baseline measures of patients granted sick leave due to common mental disorders. A total of 533 newly sick-listed individuals fulfilled the inclusion criteria and agreed to participate. A baseline questionnaire was sent by post within 3 weeks of their first day of certified medical sickness; 354 (66%) responded. Those who were unemployed were excluded, resulting in a study population of 319 individuals. Sick leave was recorded for each individual from the Social Insurance Office during 1 year. Analyses were made with multiple Cox regression analyses.

RESULTS

Early RTW was associated with lower education, better work ability at baseline, positive expectations of treatment and low perceived interactional justice with the supervisor. RTW after 3 months was associated with a need to reduce demands at work, and turnover intentions.

CONCLUSIONS

Early RTW among sick-listed individuals with common mental disorders seems to be associated with the individual's need to secure her/his employment situation, whereas later RTW is associated with variables reflecting dissatisfaction with work conditions. No health measures were associated with RTW. The study highlights the importance of considering not only health and functioning, but also workplace conditions and relations at the workplace in implementing RTW interventions.

Do unfavourable working conditions explain mental health inequalities between ethnic groups? Cross-sectional data of the HELIUS study

Background

Ethnic inequalities in mental health have been found in many high-income countries. The purpose of this study is to test whether mental health inequalities between ethnic groups are mediated by exposure to unfavourable working conditions.

Methods

Workers (n = 6278) were selected from baseline data of the multi-ethnic HELIUS study. Measures included two indices of unfavourable working conditions (lack of recovery opportunities, and perceived work stress), and two mental health outcomes (generic mental health: MCS-12 and depressive symptoms: PHQ-9). Mediation of the relationships between ethnicity and mental health by unfavourable working conditions was tested using the bias-corrected bootstrap confidence intervals technique. Linear models with and without the mediators included, and adjusted for gender and age. Attenuation was calculated as the change in B between the models with and without mediators.

Results

The sample comprised Dutch (1355), African Surinamese (1290), South-Asian Surinamese (1121), Turkish (1090), Ghanaian (729), and Moroccan (693) workers. After controlling for age and gender, all ethnic minorities had a higher risk of mental health problems as compared to the Dutch host population, with the exception of Ghanaians in the case of depressive symptoms, and African Surinamese workers with regard to both outcomes. The Turkish group stands out with the lowest mental health on both mental health indices, followed by Moroccan and South-Asian Surinamese workers. A lack of recovery opportunities mediated the relationship between ethnic group and a higher risk of mental health problems. Perceived work stress did not contribute to the explanation of ethnic inequalities.

Conclusions

The higher risk of mental health problems in ethnic minority groups can be partly accounted for by a lack of recovery opportunities at work, but not by perceived work stress. This may imply that workplace prevention targeting recovery opportunities have the potential to reduce ethnic inequalities, but ethnic-specific experiences at the workplace need to be further explored.

A Longitudinal Analysis of Changes in Job Control and Mental Health

Deteriorating job control has been previously shown to predict poor mental health. The impact of improvement in job control on mental health is less well understood, yet it is of policy significance. We used fixed-effects longitudinal regression models to analyze 10 annual waves of data from a large Australian panel survey (2001-2010) to test within-person associations between change in self-reported job control and corresponding change in mental health as measured by the Mental Component Summary score of Short Form 36. We found evidence of a graded relationship; with each quintile increase in job control experienced by an individual, the person's mental health increased. The biggest improvement was a 1.55-point increase in mental health (95% confidence interval: 1.25, 1.84) for people moving from the lowest (worst) quintile of job control to the highest. Separate analyses of each of the component subscales of job control-decision authority and skill discretion-showed results consistent with those of the main analysis; both were significantly associated with mental health in the same direction, with a stronger association for decision authority. We conclude that as people's level of job control increased, so did their mental health, supporting the value of targeting improvements in job control through policy and practice interventions.

A systematic review including meta-analysis of work environment and depressive symptoms

BACKGROUND

Depressive symptoms are potential outcomes of poorly functioning work environments. Such symptoms are frequent and cause considerable suffering for the employees as well as financial loss for the employers. Accordingly good prospective studies of psychosocial working conditions and depressive symptoms are valuable. Scientific reviews of such studies have pointed at methodological difficulties but still established a few job risk factors. Those reviews were published some years ago. There is need for an updated systematic review using the GRADE system. In addition, gender related questions have been insufficiently reviewed.

METHOD

Inclusion criteria for the studies published 1990 to June 2013: 1. European and English speaking countries. 2. Quantified results describing the relationship between exposure (psychosocial or physical/chemical) and outcome (standardized questionnaire assessment of depressive symptoms or interview-based clinical depression). 3. Prospective or comparable case-control design with at least 100 participants. 4. Assessments of exposure (working conditions) and outcome at baseline and outcome (depressive symptoms) once again after follow-up 1-5 years later. 5. Adjustment for age and adjustment or stratification for gender. Studies filling inclusion criteria were subjected to assessment of 1.) relevance and 2.) quality using predefined criteria. Systematic review of the evidence was made using the GRADE system. When applicable, meta-analysis of the magnitude of associations was made. Consistency of findings was examined for a number of possible confounders and publication bias was discussed.

RESULTS

Fifty-nine articles of high or medium high scientific quality were included. Moderately strong evidence (grade three out of four) was found for job strain (high psychological demands and low decision latitude), low decision latitude and bullying having significant impact on development of depressive symptoms. Limited evidence (grade two) was shown for psychological demands, effort reward imbalance, low support, unfavorable social climate, lack of work justice, conflicts, limited skill discretion, job insecurity and long working hours. There was no differential gender effect of adverse job conditions on depressive symptoms

CONCLUSION

There is substantial empirical evidence that employees, both men and women, who report lack of decision latitude, job strain and bullying, will experience increasing depressive symptoms over time. These conditions are amenable to organizational interventions.

Measuring quantitative and qualitative aspects of the job insecurity climate

Purpose

– The purpose of this paper is to develop and validate a measure of job insecurity climate by: first, testing whether job insecurity climate and individual job insecurity are two separate constructs; and second, investigating the relative importance of individual job insecurity and job insecurity climate in predicting work-related and health-related outcomes.

Design/methodology/approach

– Data were collected by questionnaires in a simple stratified random sample of 1,380 white-collar workers in Sweden. The response rate was 56 percent.

Findings

– Confirmatory factor analyses showed that job insecurity climate was distinct from individual job insecurity. Four separate ridge regression analyses showed that qualitative job insecurity climate was a significant predictor of demands, work-family conflict, psychological distress, and poor self-rated health and that quantitative job insecurity climate predicted demands and work-family conflict.

Research limitations/implications

– The study is based on self-reports, which may involve common method bias. The cross-sectional study design limits the possibility to make causal inferences regarding the relationship between job insecurity climate and outcomes.

Practical implications

– Future studies may consider measuring job insecurity climate in line with a referent-shift model. Work environment surveys in organizations that include measures of individual job insecurity and job insecurity climate can provide practitioners with a fuller picture of the psychosocial work environment.

Originality/value

– The present study adds to previous research by introducing a new approach to measuring and conceptualizing job insecurity climate.

Transtorno de Estresse Pós-Traumático (TEPT) em Bombeiros de Belo Horizonte, Brasil: Prevalência e Fatores Ocupacionais Associados

RESUMO O objetivo do presente estudo foi estimar a prevalência (últimos 30 dias) de Transtorno de Estresse Pós-Traumático (TEPT) e investigar se variáveis ocupacionais estão associadas ao desfecho em bombeiros de Belo Horizonte, Brasil. Estudo transversal foi realizado em 2011. Dentre 794 elegíveis, 711 (89,5%) participaram. Informações foram obtidas por questionário de autorrelato: variáveis sociodemográficas e ocupacionais, saúde e eventos extralaborais adversos. A prevalência de TEPT foi 6,9%. Variáveis ocupacionais contribuíram para explicar o desfecho no modelo final (regressão logística multivariável): fatores psicosssociais do trabalho, eventos traumáticos ocupacionais, tempo de trabalho e absenteísmo. Idade, problemas de saúde mental no passado e eventos adversos extralaborais também foram associados ao TEPT. Os resultados são discutidos considerando os pressupostos do Modelo Demanda-Controle.

The association between education and work stress: does the policy context matter?

OBJECTIVES

Several studies report socioeconomic differences in work stress, where people in lower socioeconomic positions (SEP) are more likely to experience this burden. In the current study, we analyse associations between education and work stress in a large sample of workers from 16 European countries. In addition we explore whether distinct national labour market policies are related to smaller inequalities in work stress according to educational attainment.

METHODS

We use data collected in 2010/11 in two comparative studies ('Survey of Health, Ageing and Retirement in Europe' and the 'English Longitudinal Study of Ageing'; N = 13695), with samples of men and women aged 50 to 64 from 16 European countries. We measure highest educational degree according to the international standard classification of education (ISCED) and assess work stress in terms of the demand-control and the effort-reward imbalance model. National labour market policies are measured on the basis of policy indicators which are divided into (1) 'protective' policies offering financial compensation to those excluded from the labour market (e.g. replacement rate), and (2) 'integrative' policies supporting disadvantaged individuals on the labour market (e.g. investments into active labour market policies or possibilities for further qualification in later life). In addition to country-specific analyses, we estimate multilevel models and test for interactions between the indicators of national policies and individual education.

RESULTS

Main findings demonstrate consistent associations between lower education and higher levels of work stress in all countries. The strength of this association, however, varies across countries and is comparatively small in countries offering pronounced 'integrative' policies, in terms of high investments into measures of an active labor market policy and high participation rates in lifelong learning activities.

CONCLUSIONS

Our results point to different types of policies that may help to reduce educational differences in work stress, in particular policies supporting those who are disadvantaged on the labour market.

Shift schedules, work factors, and mental health among onshore and offshore workers in the Norwegian petroleum industry

The purpose of the present study was to answer the following research questions: (1) Do workers in different shift schedules differ in mental distress? (2) Do workers in different shift schedules differ in neuroticism? (3) Do shift schedules differ in psychosocial work exposures? (4) Do psychosocial work exposures contribute to mental distress among onshore- and offshore workers? (5) Does neuroticism confound the association between work exposures and mental distress? Workers on six shift-schedules answered a questionnaire (1,471 of 2,628 employees). Psychological and social work factors were measured by QPSNordic, mental distress was measured by HADS and neuroticism was measured by EPQ. The results showed 1) No differences in mental distress between workers in different shift schedules, 2) Revolving-shift workers reported higher neuroticism compared to day workers, 3) Swing-shift workers and revolving-shift workers reported lower job control compared to permanent-night and -day workers, 4) Job demands and role conflict were associated with more mental distress. Job control, role clarity, support, and leadership were associated with lower mental distress, 5) Neuroticism influenced the relationship between psychosocial work factors and mental distress. The present study did not find differences in mental distress between shift schedules. Job characteristics may be contributing factors when determining health effects of shift work.

Associations between work environment and psychological distress after a workplace terror attack: the importance of role expectations, predictability and leader support

Experiencing terrorism is associated with high levels of psychological distress among survivors. The aim of the present study was to examine whether work environmental factors such as role clarity and predictability, role conflicts, and leader support may protect against elevated levels of psychological distress after a workplace terrorist attack. Data from approximately 1800 ministerial employees were collected ten months after the 2011 Oslo bombing attack which targeted the Norwegian ministries. The results show that after a traumatic event, lower role conflicts, higher role clarity, higher predictability, and higher leader support were independently associated with lower psychological distress. These findings suggest that the workplace environment may be a facilitator of employees’ mental health after stressful events.

Supervisor competencies for supporting return to work: a mixed-methods study

PURPOSE

Line supervisors often play an important role in the return to work (RTW) process; whether they possess the competencies needed to carry out this work effectively is unknown. The aim of this research was to determine the competencies supervisors need in order to facilitate a worker's RTW following absence due to a mental health condition or a musculoskeletal disorder.

METHODS

Supervisors from five Australian industries with high rates of compensable claims participated in focus groups to elicit the knowledge, skills, and personal characteristics required to support returning workers. From a multi-stage analysis of responses, RTW competencies were developed, allocated to clusters of related items, and incorporated into an online survey administered to rehabilitation professionals.

RESULTS

29 supervisors participated in 1 of 5 focus groups. Analysis of focus group data identified 84 generic competencies, eight specific to mental health conditions, and two to musculoskeletal disorders, arranged in 11 clusters. Survey respondents (n = 344) represented a variety of rehabilitation professionals and jurisdictions. Nearly all agreed that supervisors should receive training to support RTW. Over 50 % of respondents rated 90 of 94 competencies as very important or essential. The highest ratings were for competencies relating to personal attributes, knowledge of RTW processes, and empathetic support of the worker.

CONCLUSIONS

Supervisors and rehabilitation professionals perceive effective support of RTW requires supervisors to have a range of knowledge, skills, and personal characteristics. Our competency model should undergo workplace testing to evaluate its validity.

Occupational factors and subsequent major depressive and generalized anxiety disorders in the prospective French national SIP study

Background

The literature has been extensive on the associations between psychosocial work factors and mental health. Nevertheless, the studies using prospective design, various concepts and more than one measurement point in time for these factors and diagnostic interview to assess mental disorders remain seldom in the literature. This study is an attempt to fill the gap in this topic.

Methods

The study was based on a national representative sample of 4717 workers of the French working population (SIP survey), interviewed in 2006 and reinterviewed again in 2010 and free of mental disorders at baseline. Psychosocial work factors, measured in both 2006 and 2010, included: psychological demands, decision latitude, social support, reward, emotional demands, role conflict, ethical conflict, tensions with the public, job insecurity and work-life imbalance. Other occupational factors related to working time/hours and physical work environment were also studied. Major depressive (MDD) and generalized anxiety disorders (GAD) were measured using a standardised diagnostic interview (MINI). Covariates were age, occupation, marital status, having a child under 3 y, social support outside work and stressful life events. Multivariate analyses were performed using weighted logistic regression models.

Results

Using models taking all occupational factors into account simultaneously, low reward and job insecurity predicted MDD. Psychological demands, low reward, emotional demands and job insecurity were predictive of GAD. The more frequent the exposure to job insecurity, the higher the risk of MDD and GAD, and the more frequent the exposure to psychological demands and low reward, the higher the risk of GAD. No effect was observed for repeated exposure to occupational factors.

Conclusions

Classical and emergent psychosocial work factors were predictive factors of depression and anxiety with dose–response associations in terms of frequency of exposure. More attention may be needed on emergent psychosocial work factors and frequent exposure to these factors.

Need for recovery among male technical distal on-call workers

The objectives of this study were to (1) examine whether need for recovery differs between workers (i) not on-call, (ii) on-call but not called and (iii) on-call and called, and (2) investigate the associations between age, health, work and social characteristics with need for recovery for the three scenarios (i-iii). Cross-sectional data of N = 169 Dutch distal on-call workers were analysed with multivariate logistic regression. Need for recovery differed significantly between the three scenarios (i-iii), with lowest need for recovery for scenario (i) 'not on-call' and highest need for recovery for scenario (iii) 'on-call and called'. Poor mental health and high work-family interference were associated with higher need for recovery in all three scenarios (i-iii), whereas high work demands was only associated with being on-call (ii and iii). The results suggest that the mere possibility of being called affects the need for recovery, especially in workers reporting poor mental health, high-work demands and work-family interference. Practitioner summary: On-call work is a scarcely studied but demanding working time arrangement. We examined need for recovery and its associations with age, health, work and social characteristics among distal on-call workers. The results suggest that the mere possibility of being called can affect worker well-being and need for recovery.

Effects of work burden, job strain and support on depressive symptoms and burnout among Japanese physicians

OBJECTIVES

Days off, on call, night duty, working hours and job stress can affect physicians' mental health, and support from supervisors and co-workers may have a buffering effect. This study elucidates whether job strain and job factors affect physicians' mental health, and whether support from supervisors and co-workers has a protective effect on their mental health.

MATERIAL AND METHODS

The subjects included 494 physicians. The Brief Job Stress Questionnaire (BJSQ) was used to evaluate job demand, job control and support. High job strain was defined as a combination of high job demand and low job control. Depressive symptoms were assessed using the Patient Health Questionnaire-9. The Maslach Burnout Inventory-General Survey was used to evaluate burnout. Possible confounder adjusted logistic regression analyses were performed to obtain odds ratios for depressive symptoms and burnout.

RESULTS

As per the analysis, high job strain had significantly higher odds ratios, and support from co-workers had significant protective odds ratios for depressive symptoms. High job strain and having only 2-4 days off per month (compared to > 8 days off per month) had significantly higher odds ratios, and support from co-workers had significant protective odds ratios for burnout.

CONCLUSIONS

High job strain was related to depressive symptoms and burnout, and support from co-workers had a buffering effect on depressive symptoms and burnout. An inadequate number of days off was related to burnout. Assessment of job strain may be a good tool to measure physicians' mental health, and a sufficient number of days off may be needed to prevent burnout.

Dimensional comparability of psychosocial working conditions as covered in European monitoring questionnaires

BACKGROUND

In most countries in the EU, national surveys are used to monitor working conditions and health. Since the development processes behind the various surveys are not necessarily theoretical, but certainly practical and political, the extent of similarity among the dimensions covered in these surveys has been unclear. Another interesting question is whether prominent models from scientific research on work and health are present in the surveys--bearing in mind that the primary focus of these surveys is on monitoring status and trends, not on mapping scientific models. Moreover, it is relevant to know which other scales and concepts not stemming from these models have been included in the surveys. The purpose of this paper is to determine (1) the similarity of dimensions covered in the surveys included and (2) the congruence of dimensions of scientific research and of dimensions present in the monitoring systems.

METHOD

Items from surveys representing six European countries and one European wide survey were classified into the dimensions they cover, using a taxonomy agreed upon among all involved partners from the six countries.

RESULTS

The classification reveals that there is a large overlap of dimensions, albeit not in the formulation of items, covered in the seven surveys. Among the available items, the two prominent work-stress-models--job-demand-control-support-model (DCS) and effort-reward-imbalance-model (ERI)--are covered in most surveys even though this has not been the primary aim in the compilation of these surveys. In addition, a large variety of items included in the surveillance systems are not part of these models and are--at least partly--used in nearly all surveys. These additional items reflect concepts such as "restructuring", "meaning of work", "emotional demands" and "offensive behaviour/violence & harassment".

CONCLUSIONS

The overlap of the dimensions being covered in the various questionnaires indicates that the interests of the parties deciding on the questionnaires in the different countries overlap. The large number of dimensions measured in the questionnaires and not being part of the DCS and ERI models is striking. These "new" dimensions could inspire the research community to further investigate their possible health and labour market effects.

Recovery and recurrence of mental sickness absence among production and office workers in the industrial sector

BACKGROUND

Manual workers in the public sector have previously been found to be at risk of mental sickness absence (SA). As the impact of mental illness differs across economic sectors, this study investigated mental SA in the industrial sector, differentiating between office and production workers.

METHODS

Ten-year observational cohort study including 14 369 (8164 production and 6205 office) workers with a total of 101 118 person years. SA data were retrieved from an occupational health register. Mental SA episodes were medically certified as emotional disturbances [10th version of the International Classification of Diseases (ICD-10 R45)] or mental and behavioural disorders (ICD-10 F00-F99). The first mental SA episode since baseline was called index mental SA. Recurrences were defined as any mental SA episode occurring >28 days after recovery from index mental SA.

RESULTS

The incidence of mental SA was higher in production workers than in office workers, but office workers needed longer time to recover from mental SA. Mental SA recurred as frequently in production workers as in office workers. The median time to recurrence was 15.9 months and tangibly shorter in office workers (14.9 months) than in production workers (16.7 months). Production and office workers aged >55 years were at increased risk of recurrent mental SA within 12 months of recovery from index mental SA.

CONCLUSIONS

The incidence of mental SA was higher in production workers than in office workers, whereas recurrence rates did not differ between them. Occupational health providers should pay special attention to older workers as they are at increased risk of recurrent mental SA.

Fair relationships and policies to support family day care educators' mental health: a qualitative study

Background

High quality child care is a population health investment that relies on the capacity of providers. The mental health and wellbeing of child care educators is fundamental to care quality and turnover, yet sector views on the relationship between working conditions and mental health and wellbeing are scarce. This paper examines child care educators’ and sector key informants’ perspectives on how working in family day care influences educator’s mental health and wellbeing.

Methods

Semi-structured telephone interviews were conducted with Australian family day care educators (n = 16) and key informants (n = 18) comprised of representatives from family day care schemes, government and other relevant organisations regarding the relationship between working conditions and educator mental health. Thematic analysis referenced the assumptions and concepts of critical inquiry and used social exchange theory.

Results

Educators and key informants reported that educators’ mental health was affected by the quality of their relationships with government, family day care schemes, and the parents and children using their services. These social relationships created and contributed to working conditions that were believed to promote or diminish educators’ mental health. High quality relationships featured fair exchanges of educator work for key resources of social support and respect; adequate income; professional services; and information. Crucially, how exchanges influenced educator wellbeing was largely contingent on government policies that reflect the values and inequities present in society.

Conclusions

Making policies and relationships between educators, government and family day care schemes fairer would contribute strongly to the protection and promotion of educator mental health and wellbeing, and in turn contribute to workforce stability and care quality.

Psychological approach of occupational health service to sick leave due to mental problems: a systematic review and meta-analysis

PURPOSE

The effects of interventions by occupational health services on sick leave prompted by psychiatric disorders were examined with respect to intervention method and the number of sick leave days.

METHODS

The intervention methods used by occupational health services were systematically reviewed by searching three databases and manual searching. A meta-analysis of the number of sick leave days comparing the intervention group [intervention + care as usual (CAU)] and control group (CAU alone) was performed. In addition, subanalyses were conducted for the duration until sick-listed workers' return to work after sick leave (Subgroup 1) and the number of non-sick-listed workers' total sick leave days (Subgroup 2).

RESULTS

Ten studies were extracted and integrated, and the subjects were subsequently sorted into the intervention group (n = 434, 322, and 756 in subgroup 1, subgroup 2, and total, respectively) and control group (n = 413, 385, and 798 in subgroup 1, subgroup 2, and total, respectively). All studies employed an intervention method of problem-solving treatment or cognitive behavioral therapy (CBT). There were no significant differences between the intervention and control groups in subgroup 1 or 2. However, the combined intervention group had significantly fewer total sick leave days than the combined control group (mean difference -6.64 days, 95% CI -12.68 to -0.59, I(2) = 0%).

CONCLUSIONS

The combined study of sick-listed and non-sick-listed workers indicates occupational health services implement problem-solving treatment or CBT interventions, which can shorten total sick leave duration.

Work-related stress in midlife is associated with higher number of mobility limitation in older age-results from the FLAME study

The aim of this study is to investigate whether work-related stress symptoms in midlife are associated with a number of mobility limitations during three decades from midlife to late life. Data for the study come from the Finnish Longitudinal Study of Municipal Employees (FLAME). The study includes a total of 5429 public sector employees aged 44-58 years at baseline who had information available on work-related stress symptoms in 1981 and 1985 and mobility limitation score during the subsequent 28-year follow-up. Four midlife work-related stress profiles were identified: negative reactions to work and depressiveness, perceived decrease in cognition, sleep disturbances, and somatic symptoms. People with a high number of stress symptoms in 1981 and 1985 were categorized as having constant stress. The number of self-reported mobility limitations was computed based on an eight-item list of mobility tasks presented to the participants in 1992, 1997, and 2009. Data were analyzed using joint Poisson regression models. The study showed that depending on the stress profile, persons suffering from constant stress in midlife had a higher risk of 30-70 % for having one more mobility limitation during the following 28 years compared to persons without stress after adjusting for mortality, several lifestyle factors, and chronic conditions. A less pronounced risk increase (20-40 %) was observed for persons with occasional symptoms. The study suggests that effective interventions aiming to reduce work-related stress should focus on both primary and secondary prevention.

[Psychosocial stress environment and health workers in public health: Differences between primary and hospital care]

OBJECTIVE

To describe the psychosocial environment of health professionals in public health in primary and hospital care, and compare it with that of the general Spanish working population, as well as to evaluate the effect of psychosocial risk factors on symptoms related to perceived stress.

DESIGN

Cross-sectional study with stratified random sampling.

SETTING

Health care workers in the province of Granada, distributed in 5 hospitals and 4 health districts.

PARTICIPANTS

A total of 738 employees (medical and nursing staff) of the Andalusian Health Service (SAS) were invited to take part.

MAIN MEASUREMENTS

CopSoQ/Istas21 questionnaire developed for the multidimensional analysis of the psychosocial work environment. Stress symptoms were measured with the Stress Profile questionnaire.

RESULTS

The response rate was 67.5%. Compared with the Spanish workforce, our sample showed high cognitive, emotional, and sensory psychological demands, possibilities for development and sense of direction in their work. Primary care physicians were the group with a worse psychosocial work environment. All the groups studied showed high levels of stress symptoms. Multivariate analysis showed that variables associated with high levels of stress symptom were younger and with possibilities for social relations, role conflict, and higher emotional demands, and insecurity at work.

CONCLUSIONS

Our findings support that the psychosocial work environment of health workers differs from that of the Spanish working population, being more unfavorable in general practitioners.

Experimental Evidence That Low Social Status is Most Toxic to Well-being When Internalized

What makes low social status toxic to well-being? To internalize social status is to believe the self is responsible for it. We hypothesized that the more people internalize low subjective social status, the more their basic psychological needs are thwarted. Experiment 1 randomly assigned participants to imagine themselves in low, middle, or high social status and assessed their subjective social status internalization by independent ratings. The more participants internalized low status, the more they reported their basic psychological needs were thwarted. This effect did not appear among their higher status counterparts. Experiment 2 replicated and extended these findings using a behavioral manipulation of subjective social status and a self-report measure of internalization. We discuss implications for basic and action research.

The effort-reward imbalance work-stress model and daytime salivary cortisol and dehydroepiandrosterone (DHEA) among Japanese women

We examined the influence of work-related effort-reward imbalance and overcommitment to work (OC), as derived from Siegrist's Effort-Reward Imbalance (ERI) model, on the hypothalamic-pituitary-adrenocortical (HPA) axis. We hypothesized that, among healthy workers, both cortisol and dehydroepiandrosterone (DHEA) secretion would be increased by effort-reward imbalance and OC and, as a result, cortisol-to-DHEA ratio (C/D ratio) would not differ by effort-reward imbalance or OC. The subjects were 115 healthy female nursery school teachers. Salivary cortisol, DHEA, and C/D ratio were used as indexes of HPA activity. Mixed-model analyses of variance revealed that neither the interaction between the ERI model indicators (i.e., effort, reward, effort-to-reward ratio, and OC) and the series of measurement times (9:00, 12:00, and 15:00) nor the main effect of the ERI model indicators was significant for daytime salivary cortisol, DHEA, or C/D ratio. Multiple linear regression analyses indicated that none of the ERI model indicators was significantly associated with area under the curve of daytime salivary cortisol, DHEA, or C/D ratio. We found that effort, reward, effort-reward imbalance, and OC had little influence on daytime variation patterns, levels, or amounts of salivary HPA-axis-related hormones. Thus, our hypotheses were not supported.

Working conditions and effort-reward imbalance of German physicians in Sweden respective Germany: a comparative study

OBJECTIVE

Work stress among physicians is a growing concern in various countries and has led to migration. We compared the working conditions and the work stress between a migrated population of German physicians in Sweden and a population of physicians based in Germany. Additionally, specific risk factors for work stress were examined country wise.

METHOD

Using a cross-sectional design, 85 German physicians employed in Sweden were surveyed on working conditions and effort-reward imbalance and compared with corresponding data on 561 physicians working in Germany. Multiple linear regression analyses were applied on both populations separately to model the associations between working conditions and effort-reward ratio (ERR), adjusted for a priori confounders.

RESULTS

German physicians in Sweden had a significantly lower ERR than physicians in Germany: mean (M) = 0.47, standard deviation (SD) = 0.24 vs. M = 0.80, SD = 0.35. Physicians in Sweden worked on average 8 h less per week and reported higher work support and responsibility. Multivariate analyses showed in both populations a negative association between work support and the ERR (β = -0.148, 95% CI -0.215 to (-0.081) for physicians in Sweden and β = -0.174, 95% CI -0.240 to (-0.106) for physicians in Germany). Further significant associations with the ERR were found among physicians in Sweden for daily breaks (β = -0.002, 95% CI -0.004 to (-0.001)) and among physicians in Germany for working hours per week (β = 0.006, 95% CI 0.002-0.009).

CONCLUSION

Our findings show substantial differences in work stress and working conditions in favor of migrated German physicians in Sweden. To confirm our results and to explain demonstrated differences in physicians' work stress, longitudinal studies are recommended.

A comparison of the relationships between psychosocial factors, occupational strain, and work ability among 4 ethnic teacher groups in China

The present study compared the level of occupational strain and work ability among Han, Hui, Uygur, Hui, and Kazakh teachers, and explored ethnic differences based on the associations of psychosocial factors at work, occupational strain, and work ability. A cross-sectional survey was conducted among 2,941 teachers in primary and secondary schools in Xinjiang Province, China. Psychosocial factors, occupational strain, and work ability were measured using the Occupation Stress Inventory-Revised Edition (OSI-R) and Work Ability Index. Han and Hui teachers experienced reduced work ability compared with Uygur and Kazakh teachers, and this finding was caused, in part, by exposure to psychosocial factors at work. The vocational and psychological strains caused by these factors play an important role in reduced work ability among all ethnic teacher groups. The findings indicate the importance of taking action to reduce occupational strain for promoting teachers' work ability in multiethnic workplaces.

Psychological distress in the workforce: a multilevel and longitudinal analysis of the case of regulated occupations in Canada

Background

This study uses a multidimensional theoretical model to evaluate the role of regulated occupations and working conditions in explaining psychological distress.

Methods

Various multilevel regression analyses were conducted on longitudinal data for which measures repeated over time (n₁ = 36,166) were nested in individuals (n₂ = 7007).

Results

Results showed that when we controlled for working conditions, family situation, the social network outside the workplace, and personal characteristics, the level of psychological distress was significantly lower among professional workers in regulated occupations than among professionals not in regulated occupations. Among the working conditions studied, skill utilisation, psychological demands, and job insecurity were positively associated with psychological distress levels, whereas social support in the workplace was inversely related to distress. Finally, our results suggest that self-esteem reduced the effect of social support in the workplace on psychological distress levels in the workforce.

Conclusions

These results support our hypothesis that working in regulated occupations exerts a direct effect on mental health. These results also make clear the importance of developing new tools for measuring psychological distress among upper-level professional workers. Such tools will be much better suited to the realities characterising today's knowledge-based economies.

High job demands and lack of time: a future challenge in occupational therapy

OBJECTIVE

The aim of this study was to identify work-related stress factors that contributed to work-related stress among Swedish occupational therapists and to investigate the association between work-related stress, demographic factors, and perceived overall stress.

METHODS

A postal questionnaire and a letter of invitation were sent to 807 Swedish occupational therapists, selected at random and representing 10% of occupational therapists working in Sweden. The response rate was 59%. A stress index presenting 49 stress factors graded on a scale from 1 (indicating no source of stress) to 6 (definitely a source of stress) was included. In addition, the level of perceived overall stress during the last two weeks was scored on a rating scale with the end points 0 (no stress) and 10 (extreme stress).

RESULTS

The main findings indicated that lack of resources and lack of time were the main stressors. "Working at a superficial level due to lack of time" was the only variable associated with high overall stress when both work-related and personal factors were included. Professional identity and clarity concerning the role were graded low with regard to stress.

CONCLUSIONS

Work-related stress is just one aspect of the overall stress experienced but knowledge about its consequences highlights the importance of further studies.

Psychological and social work factors as predictors of mental distress: a prospective study

Studies exploring psychological and social work factors in relation to mental health problems (anxiety and depression) have mainly focused on a limited set of exposures. The current study investigated prospectively a broad set of specific psychological and social work factors as predictors of potentially clinically relevant mental distress (anxiety and depression), i.e. “caseness” level of distress. Employees were recruited from 48 Norwegian organizations, representing a wide variety of job types. A total of 3644 employees responded at both baseline and at follow-up two years later. Respondents were distributed across 832 departments within the 48 organizations. Nineteen work factors were measured. Two prospective designs were tested: (i) with baseline predictors and (ii) with average exposure over time ([T1+T2]/2) as predictors. Random intercept logistic regressions were conducted to account for clustering of the data. Baseline “cases” were excluded (n = 432). Age, sex, skill level, and mental distress as a continuous variable at T1 were adjusted for. Fourteen of 19 factors showed some prospective association with mental distress. The most consistent risk factor was role conflict (highest odds ratio [OR] 2.08, 99% confidence interval [CI]: 1.45–3.00). The most consistent protective factors were support from immediate superior (lowest OR 0.56, 99% CI: 0.43–0.72), fair leadership (lowest OR 0.52, 99% CI: 0.40–0.68), and positive challenge (lowest OR 0.60, 99% CI: 0.41–0.86). The present study demonstrated that a broad set of psychological and social work factors predicted mental distress of potential clinical relevance. Some of the most consistent predictors were different from those traditionally studied. This highlights the importance of expanding the range of factors beyond commonly studied concepts like the demand-control model and the effort-reward imbalance model.

The journey of recovery and empowerment embraced by nature - clients' perspectives on nature-based rehabilitation in relation to the role of the natural environment

This paper presents findings from real life situations, a longitudinal single case study on the role of natural environments in nature-based rehabilitation (NBR) for individuals with stress-related mental disorders, at the Alnarp Rehabilitation Garden in Sweden. A sample of 43 former clients voluntarily participated in semi-structured interview, and the data were analyzed according to interpretative phenomenological analysis (IPA). Three main superordinate themes were identified as the three phases of NBR-Prelude, Recuperating and Empowerment-explaining and illuminating the role of the natural environments in each phase. An explanatory model of NBR in this context is presented including the three phases of NBR, IRP supportive occupations and a pyramid of supporting environments. A new component of supportive environments was identified and herby named, Social quietness, an important component facilitating personal and intimate engagement with the natural environments.

Burnout and workload among health care workers: the moderating role of job control

BACKGROUND

As health care workers face a wide range of psychosocial stressors, they are at a high risk of developing burnout syndrome, which in turn may affect hospital outcomes such as the quality and safety of provided care. The purpose of the present study was to investigate the moderating effect of job control on the relationship between workload and burnout.

METHODS

A total of 352 hospital workers from five Italian public hospitals completed a self-administered questionnaire that was used to measure exhaustion, cynicism, job control, and workload. Data were collected in 2013.

RESULTS

In contrast to previous studies, the results of this study supported the moderation effect of job control on the relationship between workload and exhaustion. Furthermore, the results found support for the sequential link from exhaustion to cynicism.

CONCLUSION

This study showed the importance for hospital managers to carry out management practices that promote job control and provide employees with job resources, in order to reduce the burnout risk.

Occupational stress, bullying and resilience in old age

Our working years increasingly extend into the late 60s and may soon include the 70s for some people. Thus the question whether work stress has a cumulative effect in older age, and whether older employees are more vulnerable to certain sources of work stress, such as bullying in the work place, is becoming increasingly relevant. We review some of the mechanisms, which translate cumulative stress at work into ill health, particularly in older age, and summarise what is known about the effect of age-specific stress, taking age-related bullying as an example.

Work stress is associated with diabetes and prediabetes: cross-sectional results from the MIPH Industrial Cohort Studies

BACKGROUND

Diabetes is rapidly rising globally, and the relation of psychosocial stress in workplace to diabetes and prediabetes is not well investigated.

PURPOSE

The aim of the study was to examine the association of work stress with diabetes and prediabetes in a sample of German industrial workers.

METHOD

In this cross-sectional survey of an occupational cohort (n = 2,674, 77 % male), work stress was measured by the Effort-Reward Imbalance (ERI) Questionnaire. Diabetic status, i.e., diabetes and prediabetes, were diagnosed by glycated hemoglobin A1c criterion or fasting plasma glucose criterion supplemented by self-reports.

RESULTS

The overall prevalence rates of diabetes and prediabetes were 3.5 and 42.2 %, respectively. Using ordinal logistic regression with adjustment for potential confounding factors, high ERI at work was associated with diabetes-related ordinal variable (odds ratio [OR], 1.27; 95 % confidence interval [95 % CI], 1.02-1.58) and prediabetes-related ordinal variable (OR, 1.26; 95 % CI, 1.01-1.58) in men, whereas the associations in women were somewhat less pronounced and did not reach statistical significance.

CONCLUSION

The findings indicate that work stress in terms of ERI is associated with diabetes and prediabetes in German industrial male workers. If supported by prospective evidence, results point to a new approach towards primary prevention of diabetes.

Factors Related to Sleep Disorders among Male Firefighters

OBJECTIVES

The aim of this study was to investigate factors associated with sleep disorders in male firefighters working in a metropolitan city in South Korea.

METHODS

Self-administered questionnaires including the Nordic Musculoskeletal Questionnaire, Korean Occupational Stress Scale-Short Form, Psychosocial Well-Being Index-Short Form, Pittsburg Sleep Quality Index, and Beck-Depression Inventory-2 as well as surveys collecting socio-demographic characteristics and work-related factors were given to 730 male firefighters. After exclusion for missing data, 657 male firefighters were included, and logistic regression analysis adjusted for the work-related factors, psychosocial factors, and general risk factors were used to assess the relationship between sleep disorders and associated factors.

RESULTS

The prevalence of sleep disorders was 48.7%. Shift work (adjusted OR 1.58, 95% CI = 1.02-2.45), musculoskeletal symptoms (adjusted OR 2.89, 95% CI = 2.02-4.14), and depression (adjusted OR 7.04 95% CI = 4.03-12.30) were associated with sleep disorders.

CONCLUSIONS

Musculoskeletal symptoms, shift work, and depression are associated with sleep disorders. Integrated health management is needed to promote good sleep quality among firefighters.

Psychosocial work conditions and quality of life among primary health care employees: a cross sectional study

Background

Workers in Primary Health Care are often exposed to stressful conditions at work. This study investigated the association between adverse psychosocial work conditions and poor quality of life among Primary Health Care workers.

Methods

This cross-sectional study included all 797 Primary Health Care workers of a medium-sized city, Brazil: doctors, nurses, nursing technicians and nursing assistants, dentists, oral health technicians, and auxiliary oral hygienists, and community health workers. Data were collected by interviews. Quality of life was assessed using the WHOQOL-BREF; general quality of life, as well as the physical, psychological, social and environmental domains were considered, with scores from 0 to 100. Higher scores indicate a better quality of life. Poor quality of life was defined by the lowest quartiles of the WHOQOL score distributions for each of the domains. Adverse psychosocial work conditions were investigated by the Effort-Reward Imbalance model. Associations were verified using multiple logistic regression.

Results

Poor quality of life was observed in 117 (15.4%) workers. Workers with imbalanced effort-reward (high effort/low reward) had an increased probability of general poor quality of life (OR = 1.91; 1.07–3.42), and in the physical (OR = 1.62; 1.02–2.66), and environmental (OR = 2.39; 1.37–4.16) domains; those with low effort/low reward demonstrated a greater probability of poor quality of life in the social domain (OR = 1.82; 1.00–3.30). Workers with overcommitment at work had an increased likelihood of poor quality of life in the physical (OR = 1.55, 1.06–2.26) and environmental (OR = 1.69; 1.08–2.65) domains. These associations were independent of individual characteristics, job characteristics, lifestyle, perception of general health, or psychological and biological functions.

Conclusions

There is an association between adverse psychosocial work conditions and poor quality of life among Primary Health Care workers.

Validation of the Karasek-Job Content Questionnaire to measure job strain in Vietnam

The objective of this study was to validate the Karasek-Job Content Questionnaire in Vietnamese. A translation/back-translation of the questionnaire was performed prior to its administration to 344 health personnel in Vietnam. Several psychometric properties of the Vietnamese version of the Karasek-Job Content Questionnaire were assessed. A valid Vietnamese version of the Karasek-Job Content Questionnaire was produced, composed of five subscales based on the original theoretical model: Psychological demands, Social support at work, Decision latitude-Autonomy, Decision latitude-Authority, and Skill discretion. Internal consistency and reliability coefficients for each subscale of the questionnaire were satisfactory. The correlations with depression and work absence indicators were weak but statistically significant, as expected. The Vietnamese version of the Karasek-Job Content Questionnaire will help Vietnamese researchers and clinicians appropriately evaluate and document the job strain of workers in Vietnamese workplaces.

Prevalence and course of somatic symptoms in patients with stress-related exhaustion: does sex or age matter

BACKGROUND

Both mental and somatic symptoms are commonly reported in patients with stress-related problems. We have explored the prevalence of somatic symptoms in patients seeking medical care for stress-related mental health problems and followed the course of illness alongside with that the patients receive multimodal treatment.

METHOD

This study comprises data from 228 patients (69% women, mean age 43 years) who fulfilled the criteria for Exhaustion Disorder (ED). Somatic symptoms were assessed at baseline and after 3, 6, 12 and 18 months using the one-page questionnaire Primary Care Evaluation of Mental Disorders. Prevalence of different symptoms was compared between men and women and patients, over and below 40 years of age, and possible predictors of recovery were explored.

RESULTS

Tiredness and low energy are the core symptom reported by the patients. Almost all (98%) reported at least one somatic symptom and 45% reported six symptoms or more, which was similar for men and women. Nausea, gas or indigestion are the most common symptoms (67%) followed by headaches (65%) and dizziness (57%). The number of symptoms reported was significantly related to the severity of mental health problems. The only difference between the sexes was that "chest pain" and "pain or problems during sexual intercourse" were more common among males. Patients over forty more often reported "pain in arms, legs or joints, knees, hips" and this was also the only symptom that did not significantly decline during treatment. Neither sex, age, symptom duration before seeking medical care, education or any other predictor tested was shown to predict recovery in patients reporting six symptoms or more.

CONCLUSION

A heavy burden of somatic symptoms was generally seen in most patients with stress-related exhaustion. Somatic symptoms are equally common in males and females and in younger and older patients. The somatic symptoms seem to be mostly stress-related since all symptoms, except musculoskeletal pain, reduce with individualised treatment designed for stress-related mental problems. This study brings to attention the complicated burden of both somatic and mental symptoms in patients with stress-related exhaustion, raising several clinical implications of interest to discuss.
