RESUMEN
PURPOSE: This study aimed to examine longitudinal associations of workplace effort and reward with changes in cognitive function among United States workers. METHODS: Data from the national, population-based Midlife in the United States (MIDUS) study with a 9-year follow-up were used. Validated workplace effort and reward scales were measured at baseline, and cognitive outcomes (including composite cognition, episodic memory, and executive functioning) were measured with the Brief Test of Adult Cognition by Telephone (BTACT) at baseline and follow-up. Multivariable linear regression analyses based on generalized estimating equations (GEE) examined the longitudinal associations under study. RESULTS: Among this worker sample of 1,399, after accounting for demographics, socioeconomics, lifestyle behaviors, health conditions, and job control, high reward at baseline was associated with increased composite cognition (regression coefficient: 0.118 [95% CI: 0.049, 0.187]), episodic memory (0.106 [0.024, 0.188]), and executive functioning (0.123 [0.055, 0.191]) during follow-up. The joint exposure of 'high effort and high reward' was also associated with increased composite cognition (0.130 [0.030, 0.231]), episodic memory (0.131 [0.012, 0.250]), and executive functioning (0.117 [0.017, 0.216]), while the combination of 'low effort and high reward' was associated with increased composite cognition (0.106 [0.009, 0.204]) and executive functioning (0.139 [0.042, 0.235]). CONCLUSION: Findings suggest that workplace high reward is related to improved cognitive scores among United States workers. Future research should investigate larger cohorts over longer timespans and expand into disease outcomes such as dementia. If these findings emerge as causal, relevant workplace rewards to promote worker cognitive health should be considered.
RESUMEN
BACKGROUND: The contribution of psychosocial stress in the workplace to development of type 2 diabetes mellitus (T2DM) is not well investigated. As most studies were conducted in Europe, a further test from the USA seems well justified. The objective of the current investigation was to examine prospective associations of work stress based on the effort-reward imbalance model with risk of T2DM in a national sample of US workers. METHOD: Using data from the national population-based Mid-life in the United States (MIDUS) study with a prospective cohort design and a 9-year follow-up period, the effects of a ratio combining data on effort and reward at work (ER ratio) at baseline on risk of T2DM at follow-up were examined in 1493 workers who were free from diabetes at the baseline survey, applying multivariable Poisson regression analysis. RESULTS: During the follow-up, 109 individuals (7.30%) reported onset of diabetes. The analyses demonstrated a significant association between continuous data of the E-R ratio and risk of diabetes (RR and 95% CI = 1.22 [1.02, 1.46]), after adjustment for modifiable and non-modifiable risk factors at baseline. A dose-dependent response was observed with trend analysis when using quartiles of the E-R ratio. CONCLUSION: In the US workers, high effort in combination with low reward at work was significantly associated with elevated risk of T2DM 9 years later. The risk profiles of diabetes should be adapted in consideration of psychosocial work environment and taken into account by conceptualizing prevention programs of chronic non-communicable diseases.

With the introduction of medical psychology and medical sociology as examination subjects in the medical curriculum, as enacted by the year 1970 in Germany, medical faculties established professorships and departments for these disciplines. This raised the concern of how the two separate scientific cultures of the social and behavioural sciences and of medicine, rooted in basic sciences, could reconcile their teaching and research activities in a constructive way. It turned out that the quality and the thematic affinity of new research aligning with core medical interests were important preconditions of successful integration of the new disciplines. This paper exemplifies a respective success in case of a scientific development in medical sociology. Based on a theoretical model, a longstanding, internationally collaborating research program analysing social determinants of stress-related disorders resulted in a series of innovative insights. Furthermore, the paper illustrates close links between biographical luck and structural opportunities and constraints, and it emphasizes the important role of committed inter-disciplinary scientific collaboration.

BACKGROUND: Studies show that a disadvantaged socioeconomic position (SEP) and psychosocial stress at work are both independently associated with an increased risk of cardiovascular disease (CVD). But it is not clear if the effect of stress at work on CVD varies by SEP. METHODS: We used baseline and follow-up data from the French population-based cohort study CONSTANCES, including 48 383 employed women and men aged 30-70 years. Three SEP indicators (education, income, occupation), stressful psychosocial work as measured by effort-reward imbalance, pre-existing CVD and confounders were assessed at baseline, and incident non-fatal CVD events reported during annual follow-up (up to five follow-ups) were used as outcomes. The effect modification hypothesis was both investigated on an additive and multiplicative scale. RESULTS: SEP was inversely associated with CVD risk (eg, for low vs high income, OR 1.28 (95% CI 1.12 to 1.46)), and for all three components of stressful work CVD risks were significantly increased (eg, for effort-reward ratio OR 1.26 (95% CI 1.17 to 1.36)). Employees with a disadvantaged SEP showed moderately increased effect sizes of stressful work on CVD. However, no clear evidence of an effect modification was found. CONCLUSIONS: Disadvantaged SEP and stressful work contribute to higher CVD risk in this cohort. Despite moderately increased effect sizes for disadvantaged SEP groups, no evidence was found to support an effect modification hypothesis.

BACKGROUND: The world of work is facing severe challenges due to rapid technological change, globalization, climate change and, more recently, the Covid-19 pandemic. Occupational health professionals must deal with these challenges, but it is unclear how well they have been prepared for this task by their academic training programmes. AIMS: To explore content and learning objectives related to these challenges in the curricula of Occupational Medicine (OM) and Occupational Safety, Industrial Hygiene and Ergonomics (OSH), we conducted an online survey among academic leaders of these programmes in universities of several European countries. In addition, related programmes in Human Resource Management (HRM) training were included. METHODS: Selected study programmes were explored in terms of the main topics and learning objectives related to the challenges for promoting good and sustainable work in universities in Europe. The study programmes were identified through contacts with professional associations and a website search. Given the exploratory, non-representative study design, data analysis was limited to description. RESULTS: OM and OSH programmes addressed the above challenges to a very limited extent, except for their disciplinary approach to work-related diseases and injuries. In contrast, HRM programmes were dealing more extensively with globalization, climate change and digitisation. CONCLUSIONS: Significant limitations of knowledge and competences in dealing with the key challenges of the modern world of work were identified. More relational, ethical and interdisciplinary learning is needed in these programmes, addressing core issues of today's world of work.

BACKGROUND: Employees have witnessed rising trend in work stress over the last few decades. However, we know a little about country differences in those trends. Our article fills this gap in the literature by examining heterogeneities in trends in working conditions by country groups defined by their amount of investment into labor market policy (LMP) programs. Additionally, we provide findings on differences in occupational inequalities between country groups. METHODS: We use comparative longitudinal data of the European Working Conditions Surveys including cross-sectional information on employees from 15 countries surveyed in Waves 1995, 2000, 2005, 2010 and 2015. Estimation results are provided by three-way multilevel models with employees nested within country-years nested within countries. Our work stress measure is the proxy version of job strain based on the demand-control model. RESULTS: Our regression results indicate that for employees in countries with the least LMP spending job strain increased by 10% from 1995 to 2015 compared to a smaller and insignificant change in middle- and high-LMP countries. In low-LMP countries, inequalities in job strain also widened during the studied period: the gap in job strain between the highest- and lowest-skilled increased by 60% from 1995 to 2015. This contrasts a stable gap in middle- and high-LMP countries. CONCLUSIONS: Our results direct the attention to the vulnerable position of the least skilled and highlight that LMP investments may buffer some of the adverse impacts of globalization and technological changes and effectively improve the labor market situation of the least skilled.

BACKGROUND: This study aims to analyze the association between occupational stressors, evaluated by the Effort-Reward Imbalance Model (ERI), and the occurrence of common mental disorders (CMD) among healthcare workers (HCW), additionally considering mediation by over-commitment from work (OW) and mediation of gender effects by work stressors. METHODS: Cross-sectional study, including a random sample of 3343 HCWs, from six municipalities of Bahia, Brazil. The ERI scale measured the occupational stressors (main exposure), and the Self-Reporting Questionnaire (SRQ-20) was used to screen for CMD. Data analysis used Structural Equation Modeling techniques to understand the relationships between gender, occupational stressors, and the occurrence of CMD. RESULTS: ERI and OW were associated with CMD. OW mediated the negative effect of ERI on the mental health of HCW. Female workers had higher levels of ERI, OW, and CMD prevalence; the total gender effect on CMD prevalence was mediated by ERI and OW. CONCLUSIONS: The findings highlight the association of work psychosocial stressors and CMD among HCW, including partial mediation by OW. Gender inequalities persisted among HCW, with women most exposed to occupational stressors and CMD. ERI and OW partially mediated the effect of gender on CMD.

BACKGROUND: Job instability and disadvantaged work were shown to be associated with poor mental health, but few studies analyzed these conditions in a life course perspective. In this study, adverse employment histories are retrospectively assessed and linked to self-reported depression. Furthermore, indirect effects of later stressful psychosocial work in terms of effort-reward imbalance are investigated. METHODS: With data from the French CONSTANCES cohort study of 13 716 male and 12 767 female employees aged 45 and older, we identify adverse employment histories between age 25 and 45, focussing on job discontinuity, job instability and cumulative disadvantage. Direct effects of these conditions on self-reported depression over a period of up to 5 years are analyzed, using discrete-time logistic regression. Indirect effects of stressful work at baseline are examined. RESULTS: Moderately elevated odds ratios of self-reported depression are observed among participants with discontinued employment histories (number of unemployment periods; years out of work for men). Effort-reward imbalance at work is consistently related to elevated risk of self-reported depression and explains parts of the association between discontinuous employment and depression. CONCLUSIONS: Applying a life course perspective to occupational health research extends current knowledge. Specifically, adverse employment histories in terms of recurrent job discontinuity are related to the risk of self-reported depression. This association is partly explained by exposure to a stressful psychosocial work environment. These results can instruct labour market policies and the development of targeted worksite interventions that address disadvantage throughout entire employment trajectories.

The modern working world makes a significant contribution to the development of diseases, which goes far beyond the field of traditional occupational diseases. Despite technological progress and successful medical healthcare, distinct widely disseminated psychosocial working conditions contribute to a remarkable burden of work-related diseases. By inducing chronic activation of psychobiological stress reactions, they promote the development of various physical and mental disorders. To identify "toxic" constellations within the complexity and variability of modern work environments, a theoretical model is required. It aims at delineating core critical elements at a level of generalization that enables their identification in a wide range of occupations. This article describes the leading theoretical work stress models in the international research and it demonstrates their contribution towards explaining elevated disease risks among employees. Research based on prospective epidemiologic cohort studies focused specifically on depressive disorders and coronary heart diseases. Two theoretical concepts received particular attention, the demand-control and the effort-reward imbalance models. Results derived from meta-analyses indicate increased relative risks of these disorders in the range of 35-80% among those exposed to these stressors compared to nonexposed groups. Finally, practical implications of this scientific evidence for worksite screening and health promoting activities are discussed.

BACKGROUND: Given limited knowledge on the extent of social inequalities in longer-term work ability of people with a chronic disease, this study analyzes social inequalities of three consecutive indicators of work ability following medical rehabilitation in a large sample of insured employees. METHODS: Based on data from the German statutory pension insurance, a representative 20% random sample of all employed persons undergoing medical rehabilitation between 2006 and 2008 was included in a longitudinal analysis (n=219 584 persons). Three measures of consecutive work-related outcomes (physicians' assessment of work ability at discharge; return to work in the year thereafter; disability pension during follow-up) and socioeconomic position (SEP) (education, occupational position and income) were assessed. Adjusted relative risks (RRs) for each outcome were calculated according to SEP, applying Poisson regression analysis. RESULTS: The measures of SEP were associated with all three outcomes of work ability in the fully adjusted models. Relatively strongest relationships were observed for education as SEP measure, and they were particularly pronounced for 'low work ability' (RR=2.38 for lower secondary education compared to tertiary education; 95% CI: 2.26-2.51). Based on average marginal effects, absolute differences of work ability by SEP indicate a socially graded pattern, with only few exceptions. CONCLUSIONS: Despite Germany's universal access to medical and vocational rehabilitation social inequalities in longer-term work ability following chronic disease persist, thus calling for targeted programmes of prevention and occupational health promotion.

STUDY DESIGN: Cross-sectional study using data from the 2012 community survey of the Swiss Spinal Cord Injury Cohort Study. OBJECTIVES: To identify associations between selected factors related to the social background, health, functional independence, and the environment of persons with spinal cord injury (SCI) and their labor market participation. SETTING: Community-based, Switzerland. METHODS: Labor market participation (i.e., involvement in paid work or not) was determined for a sample of 966 persons with traumatic SCI who were of employable age at the time of the survey. Applying an exploratory approach, potential predictors of labor market participation were selected based on the literature and using a bidirectional stepwise variable selection approach. Descriptive statistics were calculated and weighted bootstrapped multiple logistic regressions were applied to describe the associations between the selected predictor variables and labor market participation, controlling for sociodemographic and SCI-related characteristics. RESULTS: A total of 568 (58.8%) of the participants were involved in paid work at the time of the survey. From the 17 selected predictor variables, general functional independence and Swiss citizenship showed a significant positive association, and chronic pain a negative association with involvement in paid work. CONCLUSIONS: Beyond previously established sociodemographic and injury-related risk factors such as female gender, low education, and high lesion severity, functional independence, chronic pain, and nationality proved crucial for labor market participation. These factors should receive particular attention in medical and vocational strategies striving for a sustainable work integration of persons with SCI.

Objectives: To investigate type and load of productive activities as potential determinants of mental health and well-being in elderly persons with a physical disability.Methods: We used data from a Swiss population-based sample of 314 adults at or past the legal retirement age (65 for men, 64 for women) who live with a chronic physical disability, spinal cord injury. Engagement in housework, volunteering, and paid work were dichotomized (no; some engagement) and three groups of engagement types were constructed (none; housework only; volunteering and/or paid work). Load of engagement was appraised using a sumscore on the overall frequency as well as the total number of performed activities. We used regression modelling to draw causal inference regarding the associations of type and load of engagement with general mental health (Mental Health Inventory, SF-36), self-reported depression (Self-Administered Comorbidity Questionnaire, SCQ), and well-being (WHOQoL-BREF items).Results: Engagement in volunteering was positively related to well-being. Persons engaged only in housework reported better well-being and lower prevalence of depression than non-engaged persons, however, persons engaged in volunteering or paid work reported the highest well-being and the lowest prevalence of depression. The productivity sumscore tertiles and the number of performed activities were both positively linked to well-being and negatively linked to depression, while their association with general mental health was less pronounced.Conclusion: Strengthening the engagement in productive activities among the elderly with a chronic physical disability is suggested as a promising strategy to promote well-being and reduce the prevalence of depression.

Background and Purpose- Long working hours (LWHs) are a potential risk factor for stroke. The aim of this study was to investigate this association in a large general population cohort. Methods- We used the French population-based cohort, CONSTANCES (Cohorte des Consultants des Centres d'Examens de Santé), to retrieve information on age, sex, smoking, and working hours from the baseline, self-administered questionnaire. Other cardiovascular risk factors and previous occurrence of stroke were taken from a parallel medical interview. We defined LWH as working time >10 hours daily for at least 50 days per year. Participants with primarily part-time jobs were excluded as were those with stroke before LWH exposure. We used logistic models to estimate the association between LWH and stroke, stratified by age, sex, and occupation. In additional modeling, we excluded subjects whose stroke occurred within 5 years of the first reported work exposure. Results- Among the 143 592 participants in the analyses, there were 1224 (0.9%) strokes, 42 542 (29.6%) reported LWH, and 14 481 (10.1%) reported LWH for 10 years or more. LWH was associated with an increased risk of stroke: adjusted odds ratio of 1.29 (95% CI, 1.11-1.49). Being exposed to LWH for 10 years or more was more strongly associated with stroke, adjusted odds ratio of 1.45 (95% CI, 1.21-1.74). The association showed no differences between men and women but was stronger in white-collar workers under 50 years of age. Conclusions- This large analysis reveals a significant association between stroke and exposure to LWH for 10 years or more. The findings are relevant for individual and global prevention.

BACKGROUND: Socioeconomic position (SEP) is an important contextual factor in the Stress Process Model of caregiving. However, the basic assumption that low SEP is associated with greater caregiver burden has so far lacked empirical support. The objective of this study was to investigate social inequalities in the caregiver burden among caregiving partners of persons with a physical disability, i.e., spinal cord injury (SCI), applying a dyadic approach. More specifically, we investigated 1) the association of the caregivers' SEP with caregiver burden ('actor effect'); 2) the association of the care-receivers' SEP with caregiver burden ('partner effect'), and 3) potential mediators of the association between SEP and caregiver burden. METHODS: Cross-sectional survey data from 118 couples of persons with SCI and their partners living in Switzerland was used. We firstly employed logistic regression to investigate the actor and partner effects of SEP on objective (hours of caregiving) and subjective caregiver burden (Zarit Burden Interview). We additionally used structural equation modelling to explore whether unfulfilled support needs, psychosocial resources and the care-receivers health status mediated the association between SEP and caregiver burden. SEP was operationalized by household income, education, subjective social position, financial strain and home ownership. RESULTS: We observed a consistent trend towards higher objective and subjective burden in lower SEP groups. Caregivers with higher subjective social positon and home ownership indicated lower subjective burden, and caregivers with higher education and absence of financial strain reported lower objective burden. Further evidence suggested a partner effect of SEP on caregiver burden, whereby objective caregiver burden was reduced in couples where the care-receiver had a higher educational level. The negative association between SEP and subjective burden was partially mediated by the unfulfilled support needs and deprived psychological resources of the caregiver, and the poor health status of the care-receiver. Similar mediation effects were not supported for objective burden. CONCLUSIONS: Our study, in the context of SCI, provides support for the contextual role of SEP in the Stress Process Model of caregiving. To reduce subjective caregiver burden, policy programs may target the strengthening of psychosocial resources, or the improvement of access to support services for caregivers with low SEP.

PURPOSE: Despite its importance a comprehensive assessment of health functioning has rarely been included in epidemiological investigations of work-related health outcomes. In this study, we analyzed associations of a health-adverse psychosocial work environment with a comprehensive set of subjective and objective measures of health functioning that cover the three domains of affective, cognitive, and physical functioning. METHODS: Baseline data from the French CONSTANCES cohort study were used with a sample of 24,327 employed men and women aged 45-60. Psychosocial work environment was measured by the short version of the effort-reward imbalance (ERI) questionnaire. Measures of health functioning were depressive symptoms, semantic fluency, verbal memory, walking speed, standing balance and lung function. RESULTS: First, we replicated main psychometric properties of the ERI questionnaire in the French cohort. Second, ERI scales revealed consistent associations with depressive symptoms, but less consistent links to cognitive and physical function. Among men, we observed an association of stressful work with reduced lung function. CONCLUSIONS: This study demonstrated consistent associations of stressful work in terms of effort-reward imbalance with affective functioning in a large sample of male and female employees. Relationships with physical functioning were less consistent and restricted to men, and cognitive functioning was only marginally associated with stressful work. We also established the psychometric properties of the French short version of the ERI questionnaire, thus offering a tool for guiding and harmonizing further research in this field.

PURPOSE: Cohort studies established elevated risks of depression among employees experiencing psychosocial stress at work, defined by 'job strain' or 'effort-reward imbalance' (ERI). Yet, conflicting evidence exists on whether the strength of these associations varies by gender. We explore this question in a nationally representative sample of working women and men where work stress (ERI) was related to reported depression over a 2-year follow-up. METHODS: Data were derived from the panel waves 2011 and 2013 of the German Socio-Economic Panel. Work stress was assessed by validated short scales of the ERI questionnaire, and doctor-diagnosed depression reported in 2013 (after excluding cases reported in 2011) was used as outcome variable. The sample with full data in 2013 consisted of 6693 participants (49.4% women). RESULTS: In 2011, men scored significantly higher than women on the scale 'effort' and on the 'effort-reward ratio', whereas no significant gender differences for 'reward' and 'over-commitment' were observed. Women reported a diagnosed depression almost twice as often as men (4.2 vs. 2.6%). Associations of all ERI scales with depression were statistically significant, with no noticeable differences in the strength of associations between women and men. Risk of depression was higher among men and women with effort-reward imbalance [RR (risk ratio) of 1.82; 95% CI (confidence interval) 1.36-2.44 and RR of 1.88; 95% CI 1.51-2.33, respectively]. CONCLUSIONS: Despite higher effort and slightly higher effort-reward ratio among men interaction terms between gender, work stress and depression were generally not significant. While gender inequities in the labour market are persisting stress-reducing worksite health promotion programs should apply equally for men and women.

BACKGROUND: Research evidence suggests harmful effects of overtime work on risk of heart disease. However, whether withdrawing compensation for overtime work (time-off or money) provides a relevant explanation of this association has not been explored. METHODS: Using cohort data, we included 6345 employees from Germany (3079 men and 3266 women), and applied Poisson regression analysis to examine the prospective association of overtime work without compensation with risk of self-reported incident heart disease over 2 years. RESULTS: Uncompensated overtime work was associated with an elevated risk of heart disease after adjustment for relevant variables (RR = 1.85, 95%CI: 1.05-3.25), compared to no overtime work. Stratified analyses indicated particularly strong effects among women and among employees with low socioeconomic position. CONCLUSIONS: In line with the stress-theoretical model of effort-reward imbalance at work, these findings document an important role of compensation on heart disease in the frame of overtime work.

BACKGROUND: Epidemiologic evidence for work stress as a risk factor for coronary heart disease is mostly based on a single measure of stressful work known as job strain, a combination of high demands and low job control. We examined whether a complementary stress measure that assesses an imbalance between efforts spent at work and rewards received predicted coronary heart disease. METHODS: This multicohort study (the "IPD-Work" consortium) was based on harmonized individual-level data from 11 European prospective cohort studies. Stressful work in 90,164 men and women without coronary heart disease at baseline was assessed by validated effort-reward imbalance and job strain questionnaires. We defined incident coronary heart disease as the first nonfatal myocardial infarction or coronary death. Study-specific estimates were pooled by random effects meta-analysis. RESULTS: At baseline, 31.7% of study members reported effort-reward imbalance at work and 15.9% reported job strain. During a mean follow-up of 9.8 years, 1,078 coronary events were recorded. After adjustment for potential confounders, a hazard ratio of 1.16 (95% confidence interval, 1.00-1.35) was observed for effort-reward imbalance compared with no imbalance. The hazard ratio was 1.16 (1.01-1.34) for having either effort-reward imbalance or job strain and 1.41 (1.12-1.76) for having both these stressors compared to having neither effort-reward imbalance nor job strain. CONCLUSIONS: Individuals with effort-reward imbalance at work have an increased risk of coronary heart disease, and this appears to be independent of job strain experienced. These findings support expanding focus beyond just job strain in future research on work stress.

OBJECTIVE: To explore the effect of relationship quality and reciprocity in partnerships on subjective caregiver burden and caregiver satisfaction in partners of persons with a severe physical disability (spinal cord injury). DESIGN: Cross-sectional, observational. SETTING: Community setting. PARTICIPANTS: Caregiving partners of persons with spinal cord injury (N=118). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Subjective caregiver burden measured by the Zarit Burden Interview (short form) and caregiver satisfaction measured by a single item on feelings of satisfaction resulting from the caregiver role. RESULTS: Caregiving partners who rated their relationship quality as high encountered less subjective caregiver burden (ß=-1.10; 95% confidence interval [CI], -1.47 to -0.72; P<.001) and more caregiver satisfaction (odds ratio [OR], 1.18; 95% CI, 1.01-1.45; P=.049). These associations persisted even after controlling for sociodemographic characteristics, lesion severity of the care receiver, and objective caregiver burden. Partners who indicated high reciprocity in their relationship to the care receiver indicated less subjective caregiver burden and more caregiver satisfaction when relationship quality was excluded from the final models; however, the effect of reciprocity on subjective burden (ß=-.38; 95% CI, -3.71 to 2.95; P=.82) and caregiver satisfaction (OR, 1.21; 95% CI, 0.28-5.22; P=.80) disappeared when including relationship quality. CONCLUSIONS: Results highlight the importance of relationship quality as a target for couple interventions aimed at reducing subjective caregiver burden and increasing satisfaction in the caregiving role.

BACKGROUND: Research has consistently found that favourable exchange with one's proximal social environment has positive effects on both mental health and wellbeing. Adults with physical disabilities may have fewer opportunities of favourable exchange, and therefore the effects on mental health and wellbeing may be less advantageous. The aim of this study is to systematically review quantitative studies exploring associations of social relationships with mental health and wellbeing in persons with physical disabilities. METHODS: The databases PubMed, PsycINFO and Scopus were searched for relevant studies published between 1995 and 2016. Data was extracted on study and participants' characteristics, independent and dependent variables, used measures and effects sizes of associations between social relationships and mental health or wellbeing. A narrative review was performed to synthesize findings along the constructs social support, social networks, negative social interactions, family functioning and relationship quality. RESULTS: Of the 63 included studies, 47 were cross-sectional and 16 longitudinal. Most studies included a measure of social support (n = 58), while other concepts were less often studied (social networks n = 6; negative social interaction n = 3; family functioning n = 2; relationship quality n = 1). Over half of studies included depression as outcome (n = 33), followed by wellbeing (n = 14), composite mental health measures (n = 10), anxiety (n = 8), psychological distress (n = 7), posttraumatic stress disorder (n = 3), and hopelessness (n = 1). Although trends for associations of social support with mental health and wellbeing were consistent, around a quarter of studies failed to report significant associations. Social networks were related to depression, but not to other mental health or wellbeing measures. Family functioning, negative social interactions and relationship quality showed consistent associations with mental health and wellbeing, however, only few studies were available. CONCLUSIONS: This review indicates that social relationships play an important role in mental health and wellbeing in persons with disabilities, although findings are less consistent than in general populations and strength of associations vary between constructs. Integrating persons with disabilities into social networks seems not sufficient and rehabilitation professionals together with affected persons and their peers should ensure that high quality relationships and tailored support are available.
