Effort-reward imbalance and relational injustice at work predict sickness absence: the Whitehall II study

Ambivalent identification mediates the relationship between organizational justice and stress

The present study aims to examine the relationship between organizational justice and employee stress through the lenses of social identity theory and the ambivalent identification process. The research hypotheses assume that employees working in organizational environments with low levels of justice could experience more stress, and this relationship is also mediated by ambivalent identification. In other words, the mediating mechanism of this relation posited that low levels of organizational justice were associated with high levels of ambivalent identification, which in turn increased levels of work-related stress. Across a field study in several organizations from healthcare sectors, results confirmed that employees treated with less fairness experienced high ambivalence toward their organization, which increased their perception of stress, i.e., work-related burnout, client-related burnout, physical symptoms, and interpersonal strain at work. Furthermore, results supported only a full mediation model, in which the direct relationship between organizational justice and stress was not significant. The present results make an important contribution to the research literature on justice: the inclusion of the mediator variable, namely, ambivalent identification, drops the expected direct effect of organizational justice on stress, suggesting a call for action in adopting the social identity perspective in addition to organizational justice models, and specifically introducing the study of a detrimental form of identification, such as ambivalent identification. Limitations and practical implications of the study were discussed.

Predicting disability retirement among Abu Dhabi police using multiple measure of sickness absence

Background

Disability retirement has been investigated in the last two decades using predictors such as measures of sickness absence, psychological, social, and organizational work factors. The impact of various health-related and sickness measures on disability retirement across various occupational group reveal a significant relation. However, current literature lacks understanding in police personnel.

Methods

This study examines the roles of demographic and measures of sickness absence on disability retirement among police personnel in Abu Dhabi, UAE. The case–control design was used to predict disability retirement wherein controls were matched with cases according to age and gender from those who worked in the same administration as the case at baseline, to reduce the possible confounding influence of these variables. Conditional logistic regression models were used determine the odds-ratio of various measures of sickness absence in predicting disability retirement.

Results

Results indicate that increased number of spells, and number of days of sickness absence can predict disability retirements among police personnel in the UAE. Results indicate that odds ratios for disability retirement for the total exposure period increased from 1.76 (95% CI = 1.42-2.20) for spells of 4-7d to 2.47 (95%CI = 1.79-3.40) for spells of > 4 weeks. When compared with their married counterparts, non-married police employees had a statistically significant increase in odds of disability retirement of almost three fold (OR = 2.93, 95% CI = 1.55-5.56). Non-field and field police officers, on the other hand, had significantly reduced odds of disability retirement compared with admin/supportive staff (OR = 0.43 and 0.28 with 95% CI = 0.19-0.96 and 0.13-0.61 respectively). Odds ratios of disability retirement at end of the exposure period for the matching variables with those obtained after additionally adjusting for all demographic variables (model b), namely, marital status, occupation, employment grade and type, and educational level. The odds ratios of disability retirement remained significantly raised for the total number of days of sickness absence and for the number of spells of sickness absence for all spell types.

Conclusions

Recommendation to reduce the number of future disability retirements among Abu Dhabi Police include structured problem-solving process addressed through stepwise meetings between the line-managers and the employee.

Organizational Justice and Health: Reviewing Two Decades of Studies

Organizational justice refers to employees’ perceptions of the fairness of decision-making rules and policies in the workplace. Lack of justice is suggested to be a significant psychosocial risk factor that affects employees’ attitudes and health. The aim of this narrative review was to compile the evidence available about the effects of organizational justice on health. To this end, a literature search was carried out using the Web of Science, PubMed, and PsycINFO databases. The final sample consisted of 103 articles that studied the effects of justice on mental health (40 results), job stress (26), sickness absence (15), physical health (14), absenteeism/presenteeism (3), safety at work (3), and health of third parties (2). The results show that perceptions of workplace justice predict employees’ mental health, stress-related health problems, and lower levels of sickness absence were relatively compelling. Future studies should focus on less-researched outcomes and on how these associations are modified by other variables for a better understanding of how justice affects health, with a view to being able to carry out preventive measures more efficiently.

Psychotherapeutic Consultation Services in the Workplace: A Longitudinal Analysis of Treatments and Sick Leave Using Health Insurance Data

BACKGROUND

Psychotherapeutic consultation services in the workplace (PSIW) have been developed to provide collaborative mental health care for employees. The aim of this study was to analyze participant characteristics, the role of PSIW in treatment courses, and the development of sick leave before and after PSIW start.

METHODS

Routine data from PSIW and health insurance of 155 participants were analyzed descriptively and by means of a multilevel negative binomial regression.

RESULTS

Eighty-four percent of users were male, and 72% were diagnosed with a mental disorder. The number of PSIW consultations varied from 1 to 13 (mean = 4). For 34% of participants, PSIW sessions were sufficient, 33% received a recommendation for outpatient psychotherapy, and 20% for inpatient mental health treatment. While recommendations for inpatient treatment displayed a high adherence rate (74%), recommendations for outpatient treatment were followed by 37%. Compared with the period of a half-year before PSIW, sick-leave days were reduced from the period of the second half-year after PSIW start and in the subsequent observed half-year periods. Trajectories of sick leave by subgroups showed differences.

CONCLUSIONS

PSIW is a flexible care offer, and results indicate a possible effect of PSIW on sick leave. In future studies, control group designs and inclusion of further variables are needed.

Factors associated with sickness absence in a large NHS Trust

BACKGROUND

Sickness absence rates vary widely across a large acute NHS Trust, with the highest rates in some of the largest directorates.

AIMS

This study was aimed to identify factors associated with sickness absence in teams and to inform interventions to improve staff health and well-being.

METHODS

Using 2018 data from the electronic staff record and NHS Staff Survey, we examined variables associated with cost centre sickness absence rates, perceived abuse and staff engagement scores using multivariable linear regression.

RESULTS

Data were available for 9362/15 423 (61%) of staff. Cost centre sickness absence was significantly positively associated with predominance of nursing and midwifery staff (β = 0.28 [0.012-0.55]) and significantly inversely associated with predominance of medical and dental staff (β = -0.94 [-1.2 to -0.65]) and proportion white (β = -1.11 [-1.9 to -0.37]). Cost centre sickness absence was not significantly associated with staff engagement, reported abuse, age or higher headcount. Cost centre staff engagement was significantly positively associated with proportion white (β = 0.98 [0.42-1.6]). Reported abuse by managers (β = -13 [-22 to -4.2]) and by colleagues (β = -24 [-35 to -12]) was significantly inversely associated with proportion white. Reported abuse by colleagues was significantly associated with predominance of medical and dental (β = 7.6 [2.3-13]) and nursing and midwifery staff (β = 9.1 [4.4-14]).

CONCLUSIONS

These observed associations of sickness absence, staff engagement and perceived abuse with job mix and ethnicity should be further explored. Individual or team-level data, rather than cost centre-level data, might more meaningfully elucidate why sickness absence rates vary between groups of staff.

Significance of the Dominant Psychological and Physiological Aspects of the Occupational Stress Models

The importance of the dominant psychological and physiological aspects of occupational stress models is a significant topic for researchers working in the field of medicine. Modern society faces significant problems in the detection and management of stress due to its growing impact on the functional state of working individuals. Ensuring safe and healthy working conditions is necessary to deal with the adverse effects of occupational stress on health. Controlling and reducing stress is possible by revealing the causal psychophysiological links in the mechanisms of work-related stress. Scientifically based stress management is based on the categories and concepts underlying occupational stress models. Modern work-related models of stress describe and study not only the adverse characteristics of the work process, but also the factors that stimulate the health and well-being of the individual. Monitoring occupational stress is part of the process of neutralizing and eliminating it. In today’s dynamic world, it is not enough to expect only quality performance of the professional duties of employees, but the commitment of managers working in the field of health care is needed to analyse and manage the dominant psychological and physiological aspects of occupational stress models and prevent adverse aspects of models of this type of stress at work.

Tools Appraisal of Organizational Factors Associated with Return-to-Work in Workers on Sick Leave Due to Musculoskeletal and Common Mental Disorders: A Systematic Search and Review

Purpose The objective of this study was to identify organizational factors that are predictive of return-to-work (RTW) among workers with musculoskeletal (MSD) and common mental disorders (CMD), and to subsequently catalogue and characterize the questionnaires (tools) used to measure them. Methods A systematic search on PubMed, Web of Science and PsycINFO library databases and grey literature was conducted. First, a list of organizational factors predictive of RTW for the two populations considered was built. Second, the questionnaires used to measure these factors were retrieved. Third, we looked in the scientific literature for studies on the psychometric properties and practical relevance of these questionnaires. Results Among the factors retained, perceived social support from supervisor and co-workers, work accommodations, and job strain were identified as common RTW factors. Other risk/protective factors, and associated tools, specifically targeting either people with MSD or CMD were also analysed. Conclusions Researchers and practitioners are often uncertain of which tools to use to measure organizational factors which can facilitate or hinder RTW. This study provides an evaluation of the tools measuring predictive organizational RTW factors in people with MSD and CMD. The identified tools can be used in everyday practice and/or research.

A longitudinal study of changes in interactional justice and subsequent short-term sickness absence among municipal employees

Objectives Level of perceived interactional justice has been shown to be associated with sickness absence, but less is known about the effects of changes in interactional justice. It is also unknown to what extent unmeasured, time-invariant differences contribute to the association. We investigated the association between interactional justice changes and subsequent short-term (1-3 days) sickness absences over a 12-year follow-up using between- and within-individual modeling among ageing municipal employees. Methods The data was derived from Helsinki Health Study cohort with baseline survey in 2000-2002 (N=8960, response rate 67%) and follow-up surveys in 2007 and 2012 (response rates 79% and 83%, respectively). At baseline, participants were 40-60-year-old employees of the City of Helsinki, Finland. Sickness absences from the employer's registry were linked with the responses (78%). The analytic sample was 2109 and 2070 individuals for between-individual and 4433 individuals and 8425 observations for within-individual associations. Results Negative change in interactional justice was associated with an increased risk of short-term sickness absence in between-individual models after adjusting for age and gender. Adjustment for sickness absence history attenuated the association. In within-individual models, a negative change in perceived interactional justice was associated with an increased risk of short-term sickness absence spells [incidence rate ratios (IRR) 1.05 (95% confidence interval 1.01-1.09)]. This association was robust to adjustments for gender, age, health behaviors and sickness absence history. Conclusions Paying attention to management principles - especially managerial behavior and treatment of employees to avoid the deterioration of the level of interactional justice - may provide a way of reducing self-certified short-term sickness absence spells.

The Role of Social Capital and Welfare in Absenteeism Across 26 OECD Countries: Moderating Effect on Employment and Working Conditions

OBJECTIVES

This study attempted to investigate social contextual effect on the occurrence of workers' absenteeism.

METHODS

Survey data on 30,913 wage workers in 26 countries were linked to the indicators for social capital and welfare from the national database. Multi-level logistic regression was used for analyses.

RESULTS

Employment contract, atypical work, physical and psycho-social working conditions (effort and reward), social capital and welfare significantly explained the differences in occurrence of absenteeism across countries. Analysis of cross-level interactions revealed that macro indicators related to social capital, and public social and health expenditure had moderating effects on the relation between individual-level factors and absenteeism.

CONCLUSION

High level of public spending on welfare policies and social bonding decrease the risk of absenteeism caused by vulnerable working environments, but it also worsen gaps in coping capabilities of workers in non-permanent contract and atypical work pattern.

Associations between physical and psychosocial work environment factors and sickness absence incidence depend on the lengths of the sickness absence episodes: a prospective study of 27 678 Danish employees

Objectives

This study examined if the association between work environment factors and sickness absence (SA) depended on the inclusion or exclusion of short-term SA episodes.

Methods

We linked the ‘Work Environment and Health in Denmark’ survey with the ‘Danish Register of Work Absences’ (n=27 678). Using covariate adjusted Cox regression, we examined the associations between work environment factors and SA by changing the cut-off points for the length of the SA episodes, for example, episodes ≥1 day, ≥6 days and ≥21 days. We examined three physical work environment factors: ‘Back bend or twisted’, ‘Lifting or carrying’, ‘Wet hands’ and three psychosocial work environment factors: ‘Poor influence’, ‘Role conflicts’ and ‘Bullying’.

Results

‘Back bend or twisted’ and ‘Lifting or carrying’ had small significant HRs for SA episodes ≥1 day and large and highly significant HRs for SA episodes ≥6 days and ≥21 days. ‘Wet hands’ had small significant HRs for SA episodes ≥1 day for both sexes and large and highly significant HR for ≥6 days for women. HRs of all three psychosocial factors were highly significant for SA episodes ≥1 day and ≥6 days for both sexes, and ‘Poor influence’ and ‘Role conflicts’ were significant for SA episodes ≥21 days for women.

Conclusions

The physical work factors had higher associations with SA when SA episodes of 1–5 days were excluded and focus was on SA episodes ≥6 days. The psychosocial work factors were strongly associated with SA both with and without SA episodes of 1–5 days included in the analyses.

Perceived Stress and Low-Back Pain Among Healthcare Workers: A Multi-Center Prospective Cohort Study

Objective: This study aimed to investigate the association between perceived stress and odds of low-back pain (LBP) in a population of Danish healthcare workers.

Methods: Utilizing a prospective cohort design with 1-year follow-up, a total of 1,944 healthcare workers from 389 departments at 19 hospitals responded to questionnaires containing items related to lifestyle, health, and working environment. Using Cohen's Perceived Stress Scale, associations between baseline stress levels and LBP intensity (0–10 scale) at follow-up were modeled using cumulative logistic regression, accounting for clustering at the department level and adjusting for age, sex, baseline intensity of LBP, education, seniority, number of daily patient transfers, psychosocial work environment, and lifestyle factors.

Results: For the entire population, moderate and high stress (reference: low stress) at baseline increased the odds of LBP at 1-year follow-up with odds ratios (ORs) of 1.39 (95% CI 1.13–1.71) and 1.99 (95% CI 1.49–2.66), respectively. Sensitivity analyses among female nurses showed similar results [i.e., OR 1.40 (95% CI 1.08–1.80) and OR 2.08 (95% CI 1.44–3.00) for moderate and high stress, respectively], while only high stress significantly increased the odds among those without LBP at baseline.

Conclusions: Psychological stress increases the odds of LBP among healthcare workers. Identifying and diminishing work-related psychosocial stressors should be included in strategies that aim to prevent musculoskeletal disorders in this population.

The Work Stress Questionnaire (WSQ) - reliability and face validity among male workers

BACKGROUND

The Work Stress Questionnaire (WSQ) was developed as a self-administered questionnaire with the purpose of early identification of individuals at risk of being sick-listed due to work-related stress. It has previously been tested for reliability and face validity among women with satisfying results. The aim of the study was to test reliability and face validity of the Work Stress Questionnaire (WSQ) among male workers.

METHOD

For testing reliability, a test-retest study was performed where 41 male workers filled out the questionnaire on two occasions at 2 weeks intervals. For evaluating face validity, seven male workers filled out the questionnaire and gave their opinions on the questions, scale steps and how the items corresponded to their perception of stress at work.

RESULTS

The WSQ was, for all but one item, found to be stable over time. The item Supervisor considers one's views showed a systematic disagreement, i.e. there was a change common to the group for this item. Face validity was confirmed by the male pilot group.

CONCLUSION

Reliability and face validity of the WSQ was found to be satisfying when used on a male population. This indicates that the questionnaire can be used also for a male target group.

The Association between Organizational Justice and Psychological Well-Being by Regular Exercise in Korean Employees

Many studies have shown that organizational justice (OJ) is related to psychological determinants of employees' physical and mental health in the workplace, and these health outcomes also lead to the psychological well-being (PW) of employees. Additionally, physical activity is one of the most important issues related to health in the workplace. This study compared the level of perceived OJ according to sociodemographic and lifestyle factors and examined the association between OJ and PW by regular exercise (hours per week) in Korean employees. This study used cross-sectional data obtained from 494 subjects in South Korea. Self-administered questionnaires comprising OJ, PW, and lifestyle factors (e.g., smoking, drinking, sleeping, and exercise) were completed by employees in April 2017. Multiple logistic regression analyses were conducted to estimate the association of procedural justice (PJ) and interactional justice (IJ) with the prevalence odds ratios and 95% confidence intervals of the high risk to PW. After the adjustment of sociodemographic characteristics and lifestyle factors, the main effects of PJ and IJ on the high risk to PW were significantly observed, and when these values were stratified by a regular exercise category, the lowest odds ratio was observed in a group that exercised for 1-2 h (hours per week). Organizations must encourage trust and consideration between employees and supervisors and carry out efforts to improve their environment, such as making the decision-making process fairer and encouraging employees to exercise regularly. This intervention may help prevent a high risk to PW.

Perceived stress and sickness absence: a prospective study of 17,795 employees in Denmark

Objectives

The aims were to examine (1) the prospective association between perceived stress and sickness absence, and if this association (2) differed by sex, and (3) was stronger when only long-term sickness absence (≥ 31 days) instead of all-length sickness absence (≥ 1 day) was included. Moreover, different cut-points for the length of the sickness absence periods were applied.

Methods

We followed respondents (10,634 women and 7161 men) from the ‘Work Environment and Health in Denmark’ 2014-survey for up to 18 months in the ‘Register of Work Absences’ from Statistics Denmark. Perceived stress was measured by a single question: “In the last 2 weeks, how often have you felt stressed?” We used Cox-regression with repeated events, adjusted for age, sector, education, and previous sickness absence.

Results

The hazard ratio (HR) for all-length sickness absence (≥ 1 day) for “Often/Always” stress compared to “Seldom/Never” stress was statistically significant among both men (HR = 1.25 [1.13–1.38]) and women (HR = 1.43 [1.34–1.51]). The HR was statistically significant for women (HR = 2.26 [1.89–2.70]), but not for men (HR = 1.22 [0.86–1.73]), when the analyses were restricted to long-term sickness absence (≥ 31 days). The sex-difference was statistically significant. Additional analyses with cut-points at ≥ 2, ≥ 4, ≥ 6, ≥ 8, ≥ 11, ≥ 15, ≥ 20, and ≥ 25 sickness absence days showed that among women, the HR increased gradually with increasing lengths of the sickness absence periods.

Conclusions

The prospective association of perceived stress with risk of sickness absence was stronger among women than men. Among women, perceived stress was more strongly associated with long-term sickness absence than with all-length sickness absence.

Mental disorder sick leave in Sweden: A population study

BACKGROUND

The inability to perform productive work due to mental disorders is a growing concern in advanced societies.

OBJECTIVE

To investigate medically certified mental disorder and all-cause sick leave in a working population using demographic, socioeconomic and occupational predictors.

METHODS

The study population was the entire Swedish work force aged 16-64 years in December 31st 2011. The outcome was sick leave exceeding 14 days in 2012 with adjustment for 13 confounders.

RESULTS

The risk of sick leave with a mental disorder is higher among women compared to men, among persons aged 30-39 and among parents in families with underage children. Employees in welfare service occupations within health care, education and social services have an elevated risk of mental disorder sick leave and constitute a large proportion of the workforce.

CONCLUSION

The results support the need for improving early detection and prevention of mental disorders in the workforce. Improvements in psychosocial work environments are essential, where the higher risk in female dominated welfare occupations particularly, have repercussions on the quality of the welfare services provided for vulnerable groups in society. Better work-life balance in families with younger children could also mitigate the effects of a high total workload in that particular phase of life.

Psychological Capital Research: A Meta-Analysis and Implications for Management Sustainability

The purpose of this study is to conduct a wide-ranging meta-analytic review of empirical psychological capital studies in the management field. We conducted a meta-analysis on papers collected from the EBSCOhost and ProQuest databases. For comprehensive and extensive literature coverage, we also searched and compared the Journal Citation Report for the journals that referenced the most-cited articles (e.g., Journal of Organizational Behavior, Academy of Management Journal, etc.). A total of 81 published types of research were thoroughly selected and analyzed. The results revealed that, with different weighting, the following influencing factors have significant associations with psychological capital: organizational climate, organizational justice, authentic leadership, leader–member exchange, and occupational stress. Also, with different influencing weighting, psychological capital is confirmed to have impacts on job satisfaction, attitude, performance, organizational citizenship behavior, and undesirable behaviors. Implications for managerial sustainability are discussed.

Age differences in the association between stressful work and sickness absence among full-time employed workers: evidence from the German socio-economic panel

Purpose

We aim to extend current knowledge on associations between stressful work and sickness absence, first, by studying associations between ERI and sickness absence among full-time employees from various occupations, and second, by investigating if associations vary by age.

Methods

We use data from four waves of the German socio-economic panel (GSOEP), collected among men and women between 2006 and 2012, with 9418 observations. Stressful work is measured with a short form of the ERI questionnaire. We investigate an imbalance between effort and reward (ER ratio) as well as the two main components (“high effort” and “low reward”). Sickness absence is measured by self-reported number of sickness days (assessed the following year). After descriptive analyses, we estimate a series of multivariable regressions, including tests for interactions between age and work stress.

Results

Each of the three indicators of stressful work is related to higher number of sickness days, with except of “high effort” in case of men. Findings remain significant after adjusting for social position (income, education and occupational class) and health. In addition, for both men and women, associations were slightly higher among older workers, though interactions did not reach statistical significance.

Conclusion

Our findings support that stressful work is linked to sickness absence across a wide spectrum of jobs with varying incomes and educational levels, and also that associations are slightly more pronounced among older workers.

Impact of Psychosocial Factors on Occurrence of Medication Errors among Tehran Public Hospitals Nurses by Evaluating the Balance between Effort and Reward

Background

Patient safety and accurate implementation of medication orders are among the essential requirements of par nursing profession. In this regard, it is necessary to determine and prevent factors influencing medications errors. Although many studies have investigated this issue, the effects of psychosocial factors have not been examined thoroughly.

Methods

The present study aimed at investigating the impact of psychosocial factors on nurses' medication errors by evaluating the balance between effort and reward. This cross-sectional descriptive study was conducted in public hospitals of Tehran in 2015. The population of this work consisted of 379 nurses. A multisection questionnaire was used for data collection.

Results

In this research, 29% of participating nurses reported medication errors in 2015. Most frequent errors were related to wrong dosage, drug, and patient. There were significant relationships between medications errors and the stress of imbalance between effort and reward (p < 0.02) and job commitment and stress (p < 0.027).

Conclusion

It seems that several factors play a role in the occurrence of medication errors, and psychosocial factors play a crucial and major role in this regard. Therefore, it is necessary to investigate these factors in more detail and take them into account in the hospital management.

Work ability score and future work ability as predictors of register-based disability pension and long-term sickness absence: A three-year follow-up study

AIMS

We investigated two single items of the Work Ability Index - work ability score, and future work ability - as predictors of register-based disability pension and long-term sickness absence over a three-year follow-up.

METHODS

Survey responses of 11,131 Finnish employees were linked to pension and long-term (more than 10 days) sickness absence register data by Statistics Finland. Work ability score was divided into poor (0-5), moderate (6-7) and good/excellent (8-10) and future work ability into poor (1-2) and good (3) work ability at baseline. Cox proportional hazard regressions were used in the analysis of disability pension, and a negative binomial model in the analysis of long-term sickness absence. The results were adjusted for several background, work- and health-related covariates.

RESULTS

Compared with those with good/excellent work ability scores, the hazard ratios of disability pension after adjusting for all covariates were 9.84 (95% CI 6.68-14.49) for poor and 2.25 (CI 95% 1.51-3.35) for moderate work ability score. For future work ability, the hazard ratio was 8.19 (95% CI 4.71-14.23) among those with poor future work ability. The incidence rate ratios of accumulated long-term sickness absence days were 3.08 (95% CI 2.19-4.32) and 1.59 (95% CI 1.32-1.92) for poor and moderate work ability scores, and 1.51 (95% CI 0.97-2.36) for poor future work ability.

CONCLUSIONS

The single items of work ability score and future work ability predicted register-based disability pension equally well, but work ability score was a better predictor of register-based long-term sickness absence days than future work ability in a three-year follow-up. Both items seem to be of use especially when examining the risk of poor work ability for disability but also for long sick leave.

Sickness absence due to mental disorders and psychosocial stressors at work

INTRODUCTION

Mental disorders are the third leading cause of social security benefit due to sickness in Brazil. Occupational exposure to psychosocial stressors can affect the workers' mental health. The social security medical experts are responsible for characterizing if those sicknesses are work-related.

OBJECTIVE

To evaluate the factors associated with sick leave due to mental disorders, in particular, the perception of workers on psychosocial factors at work.

METHODS

This is an analytical study carried out in São Paulo, Brazil, with 131 applicants for sickness benefit due to mental disorders. Questionnaires were applied to assess the sociodemographic data, habits/lifestyle information, and perceived psychosocial factors at work.

RESULTS

The most common diagnosis was depressive disorders (40.4%). The medical experts considered 23.7% of all applications as work-related. Most of the participants were female (68.7%), up to 40 years of age (73.3%), married/common-law marriage (51.1%), with educational level greater than or equal to 11 years (80.2%), nonsmokers (80.9%), not alcohol consumers (84%), and practice of physical activities (77.9%). Regarding psychosocial factors, most of the participants informed a high job strain (56.5%), low social support (52.7%), effort-reward imbalance (55.7%), and high overcommitment (87.0%). There was no statistical association between the work-related mental disorders sickness benefits and independent variables.

CONCLUSION

The concession of social security sickness benefits is not associated with sociodemographic data, habits/lifestyle, or psychosocial factors at work. Occupational exposure to unfavorable psychosocial factors was reported by most workers on sick leave due to mental disorders. However, several cases were not recognized by the social security medical experts as work-related, which may have influenced the results of the associations.

The impact of a sick pay waiting period on sick leave patterns

This article assesses how a waiting period for sick pay impacts sick leave patterns. In the French private sector, statutory sick benefits are granted after 3 days. However, 60 % of employers in this sector provide complementary sick pay to cover this waiting period. Linked employee-employer survey data compiled in 2009 are used to analyze the impact of this compensation on workers' sick leave behavior. The assessment isolates the insurance effect (moral hazard) from individual and environmental factors relating to sick leave (including health and working conditions). Results suggest that employees who are compensated during the 3-day waiting period are not more likely to have an absence. On the contrary, their sickness leaves are significantly shorter by 3 days on average. These results could be explained by consequences of presenteeism and ex post moral hazard when employees are exposed to a waiting period.

Association between psychosocial job characteristics and sickness absence due to low back symptoms using combined DCS and ERI models

OBJECTIVE

To evaluate the combined demand-control-support (DCS) and effort-reward-overcommitment (ERI-OC) stress models in association with sickness absence due to low back symptoms (SA-LBS).

METHODS

A total of 2,737 blue-collar workers recruited from 13 companies in the most populous province (Henan) of China were included in the study. Personal and physical job characteristics, psychosocial scales of the stress models, and SA-LBS data in the preceding year were collected by a self-reported questionnaire and analyzed by a multivariable logistic regression model. Tertile exposure levels (low, medium and high) were constructed to discriminate a risk level. Odds ratios (OR) with 95% confidence intervals (CI) were used as the association with SA-LBS.

RESULTS

A large percentage (84.5%) of the Chinese workers did not take sick leave after reporting low back symptoms during the preceding year. High job demand or medium-high reward was associated with SA-LBS. The association of the combined stress models and SA-LBS was not evident.

CONCLUSIONS

The ERI-OC model appeared to be more predictive of SA-LBS than the DCS model in the study population. The advantage of using combined stress models for predicting SA-LBS is not evident.

Association of Amplitude and Stability of Circadian Rhythm, Sleep Quality, and Occupational Stress with Sickness Absence among a Gas Company Employees-A Cross Sectional Study from Iran

Background

The present study was carried out to assess the relationship between sickness absence and occupational stress, sleep quality, and amplitude and stability of circadian rhythm as well as to determine contributing factors of sickness absence.

Methods

This cross sectional study was conducted on 400 randomly selected employees of an Iranian gas company. The data were collected using Pittsburgh sleep quality index, Karolinska sleepiness scale, circadian type inventory, and Osipow occupational stress questionnaires.

Results

The mean age and job tenure of the participants were 33.18 ± 5.64 years and 6.06 ± 4.99 years, respectively. Also, the participants had been absent from work on average 2.16 days a year. According to the results, 209 participants had no absences, 129 participants had short-term absences, and 62 participants had long-term absences. The results showed a significant relationship between short-term absenteeism and amplitude of circadian rhythm [odds ratio (OR) = 6.13], sleep quality (OR = 14.46), sleepiness (OR = 2.08), role boundary (OR = 6.45), and responsibility (OR = 5.23). Long-term absenteeism was also significantly associated with amplitude of circadian rhythm (OR = 2.42), sleep quality (OR = 21.56), sleepiness (OR = 6.44), role overload (OR = 4.84), role boundary (OR = 4.27), and responsibility (OR = 3.72).

Conclusion

The results revealed that poor sleep quality, amplitude of circadian rhythm, and occupational stress were the contributing factors for sickness absence in the study population.

Perceived Age Discrimination at Work and Subsequent Long-Term Sickness Absence Among Finnish Employees

OBJECTIVE

To investigate the association of perceived age discrimination at work with subsequent long-term sickness absence among Finnish employees.

METHODS

A representative sample of Finnish employees (n = 6322) was merged with register-based follow-up data. A negative binomial model was used in the analysis of subsequent sickness absence days.

RESULTS

Perceived age discrimination was associated to long-term sickness absence after controlling various background, work, and health-related factors.

CONCLUSIONS

Age discrimination at work is a significant risk factor for sickness absence.

The relationship between leadership and physician well-being: a scoping review

To date, research has established the individual and organizational factors that impair well-being. Thus, we are aware of the organizational “cogs and wheels” that drive well-being, and there is a sense that we can potentially utilize effective leadership to push and pull these in the appropriate directions. However, reviews of leadership in health care point to the lack of academic rigor and difficulty in reaching solid conclusions. Conversely, there is an accepted belief that the most important determinant of the development and maintenance of cultures is current – and future – leadership. Thus, leadership is assumed to be an important element of organizational functioning without the requisite evidence base. Medicine is a unique organizational environment in which the health of physicians may be a significant risk factor for inadequate patient safety and suboptimal care. Globally, physicians are reporting increasing levels of job burnout, especially among younger physicians in training. Not surprisingly, higher levels of physician burnout are associated with suboptimal care for patients and medical error, as well as maladaptive coping strategies among physicians that serve to exacerbate the former. This review is a scoping analysis of the existing literature to address the central question: is there a relationship between organizational leadership and physician well-being? The objectives of the review are as follows: 1) identify the degree to which physician health is under threat; 2) evaluate the evidence linking leadership with physician well-being; 3) identify alternative ways to approach the problem; and 4) outline avenues for future research. Finally, enhancing progress in the field is discussed in the contexts of theory, methodology, and impact.

Work stress, asthma control and asthma-specific quality of life: Initial evidence from a cross-sectional study

OBJECTIVE

Research has suggested that psychological stress is positively associated with asthma morbidity. One major source of stress in adulthood is one's occupation. However, to date, potential links of work stress with asthma control or asthma-specific quality of life have not been examined. We aimed to address this knowledge gap.

METHODS

In 2014/2015, we conducted a cross-sectional study among adults with asthma in Germany (n = 362). For the current analyses that sample was restricted to participants in employment and reporting to have never been diagnosed with chronic obstructive pulmonary disease (n = 94). Work stress was operationalized by the 16-item effort-reward-imbalance (ERI) questionnaire, which measures the subcomponents "effort", "reward" and "overcommitment." Participants further completed the Asthma Control Test and the Asthma Quality of Life Questionnaire-Sydney. Multivariable associations were quantified by linear regression and logistic regression.

RESULTS

Effort, reward and their ratio (i.e. ERI ratio) did not show meaningful associations with asthma morbidity. By contrast, increasing levels of overcommitment were associated with poorer asthma control and worse quality of life in both linear regression (ß = -0.26, p = 0.01 and ß = 0.44, p < 0.01, respectively) and logistic regression (odds ratio [OR] = 1.87, 95% confidence interval [CI] = 1.14-3.07 and OR = 2.34, 95% CI = 1.32-4.15, respectively).

CONCLUSIONS

The present study provides initial evidence of a positive relationship of work-related overcommitment with asthma control and asthma-specific quality of life. Longitudinal studies with larger samples are needed to confirm our findings and to disentangle the potential causality of associations.

Effort-reward imbalance and perceived quality of patient care: a cross-sectional study among physicians in Germany

Background

Work stress may impair physicians’ ability to provide high quality patient care. Prior research remains however sparse and has insufficiently explored explanations for this relationship. It has been suggested that physicians’ poor mental health is one potential explanatory factor. We drew on a well-established model to measure work stress (the effort-reward imbalance [ERI] model) in order to test this hypothesis. Further, to address another research gap and to potentially inform the development of better-targeted interventions, we aimed to examine associations of individual ERI constructs with the quality of care.

Methods

We used cross-sectional data, which had been collected in 2014 among 416 physicians in Germany. ERI constructs (i.e. effort, reward, the ERI ratio, and overcommitment) were measured by the established 23-item questionnaire. Physicians’ perceptions of quality of care were assessed by a six-item instrument inquiring after poor care practices or attitudes. Physicians’ mental health was operationalized by the state scale of the Spielberger's State-Trait Depression Scales. We used both continuous and categorized dependent and independent variables in multivariable linear and logistic regression analyses.

Results

Both an increasing ERI ratio and increasing effort were associated with poorer quality of care while increasing rewards were related to better care. Physicians’ depressive symptoms did not affect these associations substantially. Associations with overcommitment were weak and attenuated to non-significant levels by correction for depressive symptoms. The level of overcommitment did not modify associations between the ERI ratio and quality of care.

Conclusions

Our study suggests that high work-related efforts and low rewards are associated with reports of poorer patient care among physicians, irrespectively of physicians’ depressive symptoms. Quality of patient care may thus be improved by concurrently reducing effort and increasing rewards among physicians.

[Occupational gratification crisis and sickness absence in Germany: Cross-sectional results from the lidA-study]

BACKGROUND

Demographic change is leading to a shrinking and ageing workforce in industrialized nations. Therefore, sickness absence may become a relevant problem. Increasing absenteeism and retirement rates due to mental disorders raise the question of an association between work-related stress and sickness absence. Studies on this matter, particularly in older employees, are rare.

OBJECTIVES

We studied for the first time in Germany the relationship between effort-reward imbalance (ERI) and overall or long-term sickness absence.

MATERIALS AND METHODS

LidA ( "Living at Work") is a German cohort study on work, age, health, and work participation. A total of 6,339 employees born in 1959 and 1965 who were subject to social insurance contributions were interviewed nationwide using a representative sample concept. The response rate was 27.3 %. The sample showed high representativeness and no selectivity relating to 16 sociodemographic items. Sickness absence was defined as at least one long-term sickness absence with at least 43 days of absenteeism. Work-related stress was parameterized by ERI tertiles. Multiple logistic regression adjusting for age, sex, mental disorders, social status, and working time was performed.

RESULTS

High levels of work-related stress were significantly associated with overall and long-term sickness absence among older employees after adjusting for covariates.

CONCLUSIONS

Our unique findings on work-related stress and sickness absence in Germany are in agreement with the results of most international studies. Reducing work-related stress could help to preserve the workforce.

Is any job better than no job? Labor market experiences and depressive symptoms in people living with HIV

The purpose of this study is to determine the relationship between the psychosocial work environment and labor market experiences (including unemployment) on mental health among adults living with HIV. We used data provided by 538 participants at clinical and community sites across Ontario, Canada. Generalized estimating equation models showed that employment was associated with lower depressive symptoms. For employed participants, adverse psychosocial work conditions, specifically job insecurity, psychological demands, and decision authority were associated with depressive symptoms. For the entire sample, the number of adverse psychosocial work conditions was associated with higher depressive symptoms while participants working in poor quality jobs reported similar levels of depressive symptoms than those who were unemployed or not in the labor force. This study showed that poor quality employment (as assessed by having a high number of adverse psychosocial work exposures) was associated with a similar level of depressive symptoms as unemployment, suggesting that "bad jobs" may not offer the same mental health benefits as "good jobs." Policies to improve employment outcomes should take the quality of employment into account to maximize mental health benefits as better employment may lead to better mental health.

Factors related to health-related quality of life among Chinese psychiatrists: occupational stress and psychological capital

BACKGROUND

Psychiatry has been considered as one of the most stressful medical specialities, and psychiatrists are likely to experience impaired health-related quality of life (HRQOL). However, few studies are available in regard to related factors of HRQOL among psychiatrists in China. This study aims to evaluate the condition of HRQOL of psychiatrists and explore its predictive factors, especially the effects of occupational stress and psychological capital.

METHODS

A cross-sectional, multicenter survey was conducted among psychiatrists from different regions of Liaoning province, China, during August 2013-April 2014. Self-administrated questionnaires including the 36-item Short-Form Health Survey (SF-36), the Chinese version Psychological Capital Questionnaire, effort-reward-imbalance (ERI) scale and participants' basic characteristics were distributed to 500 psychiatrists from 10 psychiatric hospitals of 8 major cities in Liaoning province. Overall, 373 psychiatrists became our final research objects. Hierarchical multiple regression analysis (HMR) was performed to explore the predictors of psychiatrists' HRQOL.

RESULTS

The mean (SD) scores of PCS and MCS among psychiatrists were 79.78 (16.55) and 71.50 (19.24) respectively. The mean (SD) of ERR were 0.777 (0.493), and 89 (23.9%) had ERR scores above 1 (ERR > 1). Hierarchical multiple regression analysis showed that, psychiatrists' basic characteristics that significant correlated with PCS and MCS were educational level, turnover intention, and exercise; age, weekly working hours were associated with MCS; psychiatrists' experienced occupational stress (both ERR and overcommitment), and PsyCap were significant predictors for PCS and MCS.

CONCLUSIONS

Chinese psychiatrists experienced relatively good physical QOL but impaired mental QOL, and they experienced high level of occupational stress. For the sake of psychiatrists' HRQOL, the reduction of occupational stress should be implemented. The enhancement of PsyCap could be a new intervention strategy and should be paid attention to in improving HRQOL of psychiatrists. Proportionate occupational reward (money, esteem, career opportunities) to their high work demands, psychological counseling, and stress management courses should be provided to psychiatrists to improve their QOL. PsyCap, as a personal coping resource open to change, should be managed and developed among psychiatrists.

Measuring allostatic load in the workforce: a systematic review

The Allostatic Load Index (ALI) has been used to establish associations between stress and health-related outcomes. This review summarizes the measurement and methodological challenges of allostatic load in occupational settings. Databases of Medline, PubPsych, and Cochrane were searched to systematically explore studies measuring ALI in working adults following the PRISMA statement. Study characteristics, biomarkers and methods were tabulated. Methodological quality was evaluated using a standardized checklist. Sixteen articles (2003-2013) met the inclusion criteria, with a total of 39 (range 6-17) different variables used to calculate ALI. Substantial heterogeneity was observed in the number and type of biomarkers used, the analytic techniques applied and study quality. Particularly, primary mediators were not regularly included in ALI calculation. Consensus on methods to measure ALI in working populations is limited. Research should include longitudinal studies using multi-systemic variables to measure employees at risk for biological wear and tear.

A streamlined approach for assessing the Allostatic Load Index in industrial employees

Work stress is common and can lead to various bodily dysfunctions. The Allostatic Load Index (ALI) is a tool to measure the wear and tear of the body caused by chronic stress. This cross-sectional study aimed to explore the association of work-related stress and ALI in German industrial employees. A short form ALI should be developed for practical use of company physicians. In this exploration of an industrial cohort (n = 3797; 79.3% male), work stress was measured by the effort-reward imbalance (ERI) questionnaire in 2009-2011. ALI was calculated using 15 variables including anthropometric data, heart rate variability, as well as blood and urine samples based on predefined subclinical cut-off values. Differences in ALI related to low (≤1) and high (>1) ERI categories were tested. Logistic regression models estimated odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for the association between ALI and work stress controlling for multiple confounders. Employees exposed to high work stress showed higher ALI scores (p < 0.001) compared to those with low stress levels. In multivariable models, ALI was associated with work stress (OR 1.19 [95% CI: 1.00, 1.42]; p < 0.05) following adjustment for a range of potential confounders. By reducing ALI parameters to five variables this association increased modestly and remained statistically significant (OR 1.27 [95% CI: 1.05, 1.54]; p < 0.05). The results indicate that work stress is associated with ALI in German industrial employees. A short form index seems to be a promising approach for occupational health practitioners. The results should be validated in further longitudinal explorations defining a standard set of variables including gender-related thresholds.

The association of effort-reward imbalance and asthma: findings from two cross-sectional studies

PURPOSE

There is evidence to suggest that work stress is positively associated with the occurrence of asthma. A limitation is that the small number of prior studies utilized unestablished work stress measures, thus constraining interpretation and generalizability. The present study re-examined this association by assessing work stress based on the well-established effort-reward imbalance (ERI) model.

METHODS

We drew on data from two cross-sectional studies. Study 1 was conducted in a large pharmaceutical company in 2013 (n = 1,464). Study 2 was based on data from the 2011 wave of the population-based German Socio-Economic Panel (n = 8,388). ERI was assessed by validated questionnaires. Asthma was determined by self-report of a physician-based diagnosis. Associations between ERI or its subcomponents "effort", "reward" and "overcommitment" (z scores or categorized) with asthma were estimated by logistic regression models and reported as adjusted odds ratios (ORs) with 95 % confidence intervals (CIs).

RESULTS

A one standard deviation increase of the ERI score (reflecting higher work stress) was associated with a 22-48 % elevated odds of asthma (Study 1: OR 1.48, 95 % CI 1.13-1.95, and Study 2: OR 1.22, 95 % CI 1.10-1.36). Z score-based analyses of the separate ERI components generally suggested moderate associations of effort, reward and overcommitment with asthma in both studies (Study 1: OR effort 1.25, 95 % CI 0.95-1.64, OR reward 0.67, 95 % CI 0.51-0.87, OR overcommitment 1.32, 95 % CI 1.01-1.72; and Study 2: OR effort 1.21, 95 % CI 1.09-1.34, OR reward 0.83, 95 % CI 0.76-0.92, OR overcommitment 1.12, 95 % CI 1.01-1.25). Analyses of categorized exposures largely confirmed these observations.

CONCLUSIONS

This is the first study to demonstrate a link between an established work stress measure and asthma. Longitudinal studies are needed to determine the direction of these associations.

Longitudinal measurement invariance of the effort-reward imbalance scales in the Young Finns study

OBJECTIVES

In order to make valid conclusions about individual change in work-related risk factors it is important to examine whether these factors are measurement invariant over time. We tested the measurement invariance of the effort-reward imbalance (ERI) scales using the ERI Questionnaire (ERI-Q). Additionally, we examined the criterion validity of the ERI scales.

METHODS

The sample used in this study was population-based and comprised 2128 participants (56.6% women) in full-time employment. Data on effort, reward and self-reported general stress were collected in 2007 and 2012. Measurement invariance was assessed separately for the effort and reward scales, with reward treated as a first-order and as a second-order variable. Criterion validity of the ERI scales was also examined using a single-item measure of general stress.

RESULTS

Effort and reward were found to be measurement invariant over time, that is, they measured the same latent variable across both time points. Furthermore, ERI and its components showed adequate criterion validity, and effort was additionally found to prospectively predict general stress 5 years later (β=0.072, 95% CI 0.013 to 0.131).

CONCLUSIONS

Our results indicate that changes in the scores of the ERI scales are more likely caused by changes in perceptions of work characteristics than by changes in the construct of the scales. Additionally, the results support the criterion validity of ERI and its components.

Psychosocial work environment and intention to leave the nursing profession: a cross-national prospective study of eight countries

Many countries throughout the world are facing a serious nursing shortage, and retention of nurses also is a challenge. The aim of this study was to compare the predictive contribution of a broad spectrum of psychosocial work factors, including job strain, effort-reward imbalance, and alternative employment opportunity, to the probability of intention to leave the nursing profession. A total of 7,990 registered female nurses working in hospitals in eight countries (Germany, Italy, France, The Netherlands, Belgium, Poland, Slovakia, and China) were included in the one-year prospective study. A standardized questionnaire on job strain, effort-reward imbalance, employment opportunity, and intention to leave the nursing profession was used in the survey. Multilevel logistic regression modeling was used to analyze the data. Results showed that an imbalance between high effort and low reward (in particular, poor promotion prospects) and good employment opportunity at baseline were independently associated with a new intention to leave the nursing profession at follow-up. However, job strain appeared to have relatively less explanatory power. Findings suggest that interventions to improve the psychosocial work environment, especially the reciprocity experienced between effort and reward, may be effective in improving retention of nurses and tackling the international nursing shortage.

Effort--reward imbalance and medically certified absence for mental health problems: a prospective study of white-collar workers

OBJECTIVE

Little is known about the effects of psychosocial work factors on objectively assessed mental health problems leading to medically certified absence. Only one study has evaluated the prospective effects of effort-reward imbalance (ERI) at work with regards to this outcome. The present study aimed to evaluate the effects of ERI on the incidence of medically certified absence for mental health problems.

METHODS

The study included 2086 white-collar workers (63.3% women) employed in public organisations in Quebec city. Participants were followed over a 9-year period. Medical absences from work were collected from employers' files and psychosocial factors were measured using the ERI questionnaire. Cox regression models were used to estimate the incidence of certified sickness absence due to mental health problems that lasted 5 workdays or more, while controlling for confounders.

RESULTS

Workers exposed to ERI had a higher risk of a first spell of medically certified absence for mental health problems (HR=1.38, 95% CI 1.08 to 1.76) compared with unexposed workers. Low reward was significantly associated with a high risk among men (HR=2.80, 95% CI 1.34 to 5.89) but not in women. (HR=1.24, 95% CI 0.90 to 1.73). Effort at work had no effect on certified absence. All these effects were adjusted for potential confounders.

CONCLUSIONS

ERI and low reward at work were prospectively associated with medically certified absence for mental health problems. These effects seem to differ by gender. Primary prevention that is aimed at reducing these stressors should be considered to help reduce the incidence of such severe mental health problems.

Primary school teachers in China: associations of organizational justice and effort-reward imbalance with burnout and intentions to leave the profession in a cross-sectional sample

OBJECTIVE

We examined associations of organizational justice (OJ) and effort-reward imbalance (ERI) with burnout and intentions to leave the teaching profession (ILTP) among primary school teachers in China.

METHODS

Six primary schools located in Wuhan, China, were randomly selected from three different socioeconomic areas in 2010. In total, these schools employed 533 teachers, and 436 of these (82 %) participated in a cross-sectional survey. OJ and ERI were assessed by 13-item and 10-item questionnaires, respectively. Burnout was measured using the emotional exhaustion subscale of the Chinese Maslach Burnout Inventory. ILTP were operationalized based on the frequency of thoughts about turnover during the past year. Logistic regression-based odds ratios (ORs) with 95 % confidence intervals (CIs) were estimated separately for OJ and ERI. In a second step, these work stress scales were entered into the same regression model.

RESULTS

Separate regression models suggested moderate to strong associations of OJ and ERI with burnout and ILTP. After simultaneous adjustment, the overall OJ score remained associated with burnout and ILTP, but ERI appeared to be the stronger and more consistent determinant of both outcomes. For instance, an increase of 1 standard deviation of the ERI score was associated with an OR of 2.60 (95 % CI 1.97-3.43) for burnout and with an OR of 2.26 (95 % CI 1.66-3.08) for ILTP.

CONCLUSIONS

Organizational justice and in particular ERI appeared to be determinants of burnout and ILTP among primary school teachers in China.

The combination of work organizational climate and individual work commitment predicts return to work in women but not in men

OBJECTIVE

To analyze if the combination of organizational climate and work commitment can predict return to work (RTW).

METHODS

This prospective Swedish study was based on 2285 participants, 19 to 64 years old, consecutively selected from the employed population, newly sick-listed for more than 14 days. Data were collected in 2008 through postal questionnaire and from register data.

RESULTS

Among women, the combination of good organizational climate and fair work commitment predicted an early RTW with an adjusted relative risk of 2.05 (1.32 to 3.18). Among men, none of the adjusted variables or combinations of variables was found significantly to predict RTW.

CONCLUSIONS

This study demonstrated the importance of integrative effects of organizational climate and individual work commitment on RTW among women. These factors did not predict RTW in men. More research is needed to understand the RTW process among men.

The Different Facets of Work Stress

Work-related stress has been identified as a relevant problem leading to negative effects on health and quality of life. Using data from 844 nurses, latent profile analyses (LPA) were applied to identify distinct patterns of work stress. Several sociodemographic variables, including nurses’ working and living conditions, as well as nurses’ reactions to workload, were considered to predict respondents’ profile membership. LPA revealed three distinct profiles that can be distinguished by a low, moderate, and higher stress level. Being financially secure is positively related to the low stress profile, whereas working in an urban area and having low job satisfaction increases the chance of belonging to the higher stress profile. Our results can be used as a basis to develop interventions to create a healthy nursing home environment by supporting the balance between family and work, providing access to job resources and optimizing recovery opportunities.
