The Relationship Between Work-Related Stress and Depression: A Scoping Review.

Objectives: Work-related stress is highly prevalent. Recent systematic reviews concluded on a significant association between common work-related stress measures and depression. Our scoping review aims to explore whether work-related psychosocial stress is generally associated with depression or depressiveness, the extent and methodology of the primary research undertaken on this topic and to elucidate inconsistencies or gaps in knowledge. Methods: We searched for literature in Pubmed, PsycInfo and Web of Science including full reports in seven languages published between 1999 and 2022 and applied the PRISMA statement for scoping reviews criteria. Results: Of 463 primarily identified articles, 125 were retained after abstract and full-text screening. The majority report significant associations between work-related stress and depression. Cross-sectional studies are most prevalent. Sufficient evidence exists only for job strain and effort-reward imbalance. Most studies are from Asia, North America and Europe. The health sector is the most studied. Several research gaps such as the lack of interventional studies were identified. Conclusion: The consistency of most studies on the significant association between work-related stress and depression is remarkable. More studies are needed to improve evidence and to close research gaps.

Development of Harmonized COVID-19 Occupational Questionnaires.

Harmonized tools and approaches for data collection can help to detect similarities and differences within and between countries and support the development, implementation, and assessment of effective and consistent preventive strategies. We developed open source occupational questionnaires on COVID-19 within COVID-19 working groups in the OMEGA-NET COST action (Network on the Coordination and Harmonisation of European Occupational Cohorts, omeganetcohorts.eu), and the EU funded EPHOR project (Exposome project for health and occupational research, ephor-project.eu). We defined domains to be included in order to cover key working life aspects of the COVID-19 pandemic. Where possible, we selected questionnaire items and instruments from existing questionnaire resources. Both a general occupational COVID-19 questionnaire and a specific occupational COVID-19 questionnaire are available. The general occupational COVID-19 questionnaire covers key working life aspects of the COVID-19 pandemic, including the domains: COVID-19 diagnosis and prevention, Health and demographics, Use of personal protective equipment and face covering, Health effects, Work-related effects (e.g. change in work schedule and work-life balance), Financial effects, Work-based risk factors (e.g. physical distancing, contact with COVID-19-infected persons), Psychosocial risk factors, Lifestyle risk factors, and Personal evaluation of the impact of COVID-19. For each domain, additional questions are available. The specific occupational COVID-19 questionnaire focusses on occupational risk factors and mitigating factors for SARS-CoV2 infection and COVID-19 disease and includes questions about the type of job, amount of home working, social distancing, human contact (colleagues, patients, and members of the public), commuting, and use of personal protective equipment and face coverings. The strength of this initiative is the broad working life approach to various important issues related to SARS-CoV-2 infection, COVID-19 disease, and potentially future pandemics. It requires further work to validate the questionnaires, and we welcome collaboration with researchers willing to do this. A limitation is the moderate number of questions for each of the domains in the general questionnaire. Only few questions on general core information like ethnicity, demographics, lifestyle factors, and general health status are included, but the OMEGA-NET questionnaires can be integrated in existing questionnaires about sociodemographic and health-related aspects. The questionnaires are freely accessible from the OMEGA-NET and the EPHOR homepages.

Exploring brainstem auditory evoked potentials and mental development index as early indicators of autism spectrum disorders in high-risk infants.

This study of infants from Hubei Province, China examined brainstem auditory evoked potentials (BAEP) and mental development index (MDI) as possible early indicators associated with autism spectrum disorders (ASD). The 34 ASD cases and 102 controls who had recovered from perinatal conditions were matched for age, sex, gestational age, birth weight and maternal age. BAEP absolute latencies (AL) I, III, V and interpeak latencies (IPL) I-III, III-V, I-V were compared in ASD cases and controls at ages 1, 3 and 6 months. MDI scores were compared in these infants from 1 month to 2 years old. Multiple logistic regression analysis was performed to test associations among ASD, BAEP and MDI. Results showed BAEP AL I, V and IPL III-V prolonged in the ASD group (p < 0.001), and MDI scores in ASD cases sharply declining from 12 to 24 months (p < 0.001). Regression analysis revealed odds ratios (OR) indicating that ASD was likely associated with abnormal values of BAEP AL I at 1 and 3 months (ORAL I : 4.27; ORAL I : 4.13), and AL V at 6 months (ORAL V : 7.85). Lower MDI scores (MDI < 80) in infants at 1, 3, and 6 months were likely associated with ASD (ORMDI : 2.58; ORMDI : 3.83; ORMDI : 4.87). These data show that abnormal BAEP values and low MDI scores are independent factors associated with ASD, and that monitoring of BAEP and MDI during infancy might facilitate screening for ASD development.

The differentiated roles of health in the transition from work to retirement - conceptual and methodological challenges and avenues for future research.

OBJECTIVES: The aim of this discussion paper is to (i) identify the differentiated roles of health in the work-retirement transition, and, with respect to these, (ii) highlight topics related to conceptual and methodological problems and challenges in research, and (iii) present avenues for future research. METHODS: This discussion paper summarizes an OMEGA-NET working group discussion ongoing from November 2018 to September 2021 with face-to-face and online meetings as well as a written online discourse. RESULTS: 'Health' and 'retirement' are ambiguous concepts. With respect to both, in retirement research, the choice of concept and indicator influences the findings. In addition, the impact of health on retirement is not necessarily a direct one, but can be influenced by further factors such as the ability, motivation and opportunity to work. The strong overall association of poor health with retiring early (path 1) bears the risk of masking distinct and deviating mechanisms in subgroups. In fact, there is evidence that also good health may lead to early retirement (path 2), while both poor health (path 3) and good health (path 4) may also make people retire later. CONCLUSIONS: An increased awareness of the differentiated roles that health may have in the work-retirement transition as outlined in this discussion paper may support research to address questions relevant for policy and practice and increase the impact of research. Recommendations for occupational health and social research are given.

Medical rehabilitation of older employees with migrant background in Germany: Does the utilization meet the needs?

Due to demographic change with an ageing workforce, the proportion of employees with poor health and a need for medical rehabilitation is increasing. The aim was to investigate if older employees with migrant background have a different need for and utilization of medical rehabilitation than employees without migrant background. To investigate this, self-reported data from older German employees born in 1959 or 1965 of the first and second study wave of the lidA cohort study were exploratory analyzed (n = 3897). Subgroups of employees with migrant background were separated as first-generation, which had either German or foreign nationality, and second-generation vs. the rest as non-migrants. All subgroups were examined for their need for and utilization of medical rehabilitation with descriptive and bivariate statistics (chi-square, F- and post-hoc tests). Furthermore, multiple logistic regressions and average marginal effects were calculated for each migrant group separately to assess the effect of need for utilization of rehabilitation. According to our operationalizations, the foreign and German first-generation migrants had the highest need for medical rehabilitation while the German first- and second-generation migrants had the highest utilization in the bivariate analysis. However, the multiple logistic model showed significant positive associations between their needs and utilization of rehabilitation for all subgroups. Further in-depth analysis of the need showed that something like under- and oversupply co-exist in migrant groups, while the foreign first-generation migrants with lower need were the only ones without rehabilitation usage. However, undersupply exists in all groups independent of migrant status. Concluding, all subgroups showed suitable use of rehabilitation according to their needs at first sight. Nevertheless, the utilization does not appear to have met all needs, and therefore, the need-oriented utilization of rehabilitation should be increased among all employees, e.g. by providing more information, removing barriers or identifying official need with uniform standards.

[Utilization of Medical Rehabilitation and Access Barriers for Persons with a Migrant Background - Results of the lidA Cohort Study]. / Inanspruchnahme medizinischer Rehabilitation und Zugangsbarrieren bei Personen mit Migrationshintergrund ­ Ergebnisse der lidA-Kohortenstudie.

INTRODUCTION: Rehabilitation services are considerably less used by persons with a migration background of working age in Germany than by persons without migration background. One reason could be access barriers. They can arise both from the structures of the health/rehabilitation system as well as from influences of the personal environment, e. g. financial burdens incurred through the use of rehabilitation or cultural expectations. In addition to the migration status, other factors such as country of origin, reasons for immigration, length of stay as well as the religious affiliation and social status could influence the utilization of medical rehabilitation. It was examined to what extent differences in utilisation are due to the migration background and to migration-independent personal barriers to access. METHODS: The lidA-study is a nationwide, representative prospective cohort study among employees with insurable employment born in 1959 and 1965 with a focus on work, age, health and employment. Data from the first (2011) and the second wave (2014) were combined for the analyses. In addition to bivariate analyses to describe the sample according to migration status, logistic regression analyses were carried out to estimate the odds ratios for the influence of migration background or nationality and other factors on the use of a medical rehabilitation measure. RESULTS: The chance of receiving medical rehabilitation is increased for migrants of the 1st generation (odds ratio (OR) 1.56, 95% confidence interval (CI): 1.09-2.25). If predominantly or exclusively no German is spoken at home, this could be associated with a comparatively much lower chance of utilisation (OR: 0.56, 95% CI: 0.28-1.15). Because only nationality is often available in routine data to determine the status of migration, another model only considers migrants and 2nd generation nationals and examines the influence of nationality on utilisation. A foreign nationality was not associated with a higher utilisation (OR: 1.07, 95% CI: 0.55-2.08). DISCUSSION: Results of previous studies on the use of medical rehabilitation for people with a migration background are inconsistent. This could be due to different examined population groups, different indications for rehabilitation, a temporal change in utilisation and the various study designs as well as data sources. We found a higher use of medical rehabilitation services by persons with a migrant background (1st generation) compared to non-migrant persons. One reason could be our more precise definition of the migration background compared to analyses of routine data. If predominantly or exclusively another language than German is spoken at home, the utilisation tends to be lower. The finding coincides with a lack of German language skills described as an access barrier in the literature.

Work profiles of older employees in Germany-results from the lidA-cohort study.

BACKGROUND: This study investigates whether a typology of work exposure can be established among older workers in Germany. Work exposure comprises physical work, working time quality, work intensity, skills & discretion, social environment, leadership, continued education, earnings and work prospects. METHODS: Latent profile analysis was conducted on a representative sample of the socially insured workforce in Germany born in 1959 or 1965 (N = 6277). Seven year-prospective associations between the typology and work-related outcomes (physical and mental health, work ability and work-privacy-conflict) were investigated to establish the distinctness of the profiles. RESULTS: Five profiles were identified: "Poor Quality" (19%), "Relaxed Manuals" (30%), "Strained non-Manuals" (16%), "Smooth Running" (33%) and "High Flying" (3%). These profiles exhibited diverging patterns of association with the selected outcomes, thus representing qualitatively distinct subgroups of older workers in Germany. CONCLUSIONS: We conclude that a typological approach may broaden the understanding of the ageing work force and the complex interplay of the overall work situation with outcomes of high individual and social relevance such as health, work ability and employment. The five work profiles identified in this study may constitute crucial clusters needed to reliably mirror today's over-all work exposure patterns in the older work force in Germany. They may allow for the comprehensible monitoring of quality of work and personal life among the older work force during their last working years and their transition to retirement in current times of extending working lives.

Subjective employment perspective among older workers with and without migrant background in Germany-Results of the lidA cohort study.

OBJECTIVES: The aim of this study was to investigate the subjective employment perspective in higher working age for different employee groups with migrant background (EMB) and without (non-EMB), meaning willing, being able, and planning to work until the individual state pension age (iSPA). METHODS: A representative sample of socially insured employees born in 1959 or 1965 was surveyed in 2011, 2014, and 2018 with computer-assisted personal interviews. The current cross-sectional analysis is based on data from the third study wave (n = 3286) of the lidA cohort study. EMB were differentiated via generation (first generation, G1, vs second generation, G2) or nationality (German vs foreign). Applying bivariate statistics with the tests of independence and block-wise logistic regressions, group differences were investigated. Sex, age, educational level, net household income, health, and work factors were considered as covariates. RESULTS: When comparing subgroups of EMB, significant differences appeared in bivariate analyses for willing and planning to work. G1 were to a higher degree planning to work longer than G2 and those with foreign nationality were more willing and planning than those with German nationality. Multivariate analyses revealed significant differences of G1 and non-EMB for planning, being significant in the fully adjusted model, but not for willing. CONCLUSION: The findings underline the need for differentiation of migrant groups in social research and policy. When it comes to extended working lives, the first-generation migrant group, as well as foreigners may constitute risk groups and require increased attention from a work, health, and economic point of view.

Utilisation of medical rehabilitation services by persons of working age with a migrant background, in comparison to non-migrants: a scoping review.

In Germany, an ageing population is affected by societal and political changes due to demographic transition, e.g. by a prolonged working life for older employees. Demographic change also influences persons of higher working age with a migrant background. In 2018, 25% of all employees in Germany had a migrant background. Those affected by poor health at a higher working age can benefit from medical rehabilitation services, which aim to prevent early retirement and disabilities. So far, the utilisation of medical rehabilitation has been lower among persons of foreign nationality (often the only available proxy for migrant background), compared to that of Germans. The aim of this scoping review is to assess the utilisation of medical rehabilitation services by those with migrant background (PMB) and those without (non-PMB) and to identify the differences between these groups. We included 25 studies in our analysis, which were mainly secondary analyses of routine data and also a small number of primary studies. The results were inconsistent: studies published before 2018 showed a lower use of rehabilitation services for persons of foreign nationality compared to Germans. However, no differences were found between PMB and non-PMB in studies published in 2018 or later. PMB, as well as foreign nationals, showed poorer health before medical rehabilitation utilisation and had a higher chance of occupational disease and a lower education level. We identified a lower work-related performance, as well as barriers (e.g. information deficits) in the utilisation of rehabilitation services for groups of PMB. Our review is limited in that we cannot generalise our results to all PMB living in Germany. This is because of the heterogeneity, the limited number of studies and lack of representativeness in some studies. In many cases, studies only analyse the nationality, but they lack information about the second generation PMB. Future studies should survey the utilisation of medical rehabilitation services by migrant background rather than by nationality and focus on changes in the provision of rehabilitation measures following diversity-centred strategies.

Utilisation of rehabilitation services for non-migrant and migrant groups of higher working age in Germany - results of the lidA cohort study.

BACKGROUND: An ageing and a shrinking labour force implies that the prevention of a premature exit from work due to poor health will become more relevant in the future. Medical rehabilitation is a health service that aims at active participation in working life. The provision of this service will be relevant for an increasing part of the ageing labour force, namely, employees with a migrant background and their different subgroups. Thus, this study examines whether first- and second-generation employees with migrant background differ from non-migrants in their utilisation of rehabilitation services and whether within the subsample of migrant employees, those persons with foreign nationality differ from those with German nationality. METHODS: Socially insured employees born in 1959 or 1965 were surveyed nationwide in 2011 as part of the lidA cohort study (n=6303). Survey data of the first study wave were used to identify the dependent variable of the utilisation of rehabilitation (in- and outpatient), the independent variable of migrant status and the covariates of sociodemographic, work- and non-work-related factors. Applying bivariate statistics with tests of independence and block-wise logistic regressions, differences between the groups were investigated. Additionally, average marginal effects were computed to directly compare the adjusted models. RESULTS: The study showed that first-generation migrants had a significantly lower likelihood of utilising outpatient rehabilitation than non-migrants (fully adj. OR 0.42, 95% CI 0.22-0.82) and that average marginal effects indicated higher differences in the full model than in the null model. No significant differences were found between the first- or second-generation migrants and non-migrants when comparing the utilisation of inpatient rehabilitation or any rehabilitation or when analysing German and foreign employees with migrant background (n=1148). CONCLUSIONS: Significant differences in the utilisation of outpatient rehabilitation between first-generation migrants and non-migrants were found, which could not be explained by sociodemographic, work- and non-work-related factors. Thus, further factors might play a role. The second-generation migrants resemble the non-migrants rather than their parent generation (first-generation migrants). This detailed investigation shows the heterogeneity in the utilisation of health services such as medical rehabilitation, which is why service sensitive to diversity should be considered.

The Role of Leisure-Time Physical Activity in the Change of Work-Related Stress (ERI) over Time.

BACKGROUND: Every second employee in Europe complains about work-related stress. Occupational stress due to an imbalance between efforts spent and rewards gained (effort-reward imbalance = ERI) is well investigated and it is associated with mental and physical health. A common guess is that leisure-time physical activity (LTPA) has beneficial effects on work-related stress. Yet, evidence in support of this assumption is weak, especially regarding ERI-stress. Longitudinal studies investigating the role of LTPA on ERI are missing. Therefore, this study aims to investigate the effect of LTPA on work-related stress by ERI over time. METHODS: 3961 socially insured employees that were born in 1959 or 1965 and working in the first (t1: 2011) and second wave (t2: 2014) of the lidA-study were included. Work-related stress was measured by ERI, LTPA by the self-rated weekly frequency of physical activities. Besides the direct effect, a moderating effect of LTPA on ERI over time was tested in the multiple linear regression analysis. RESULTS: The ERI at t1 was strongly associated with ERI at t2. While LTPA had no direct effect on ERI(t2), it was a significant moderator of ERI from t1 to t2: The higher the frequency of LTPA, the lower ERI was over time. This interaction of LTPA with ERI remained after adjustment for socio-demographic factors. CONCLUSIONS: The long-term moderating effect of LTPA on ERI is in agreement with former investigations on the role of LTPA on work-related stress, generally, and on its cross-sectional effect on ERI-stress, specifically. Some of Hill's criteria of a causal association in epidemiology (biological gradient, temporality, consistency) support our findings. As LTPA has also been shown to exert a protective effect on health outcomes that are associated with ERI, the moderation of ERI by LTPA could partly explain this protective effect. Future observational and interventional studies are required to support our results over more than two age groups and study times.

[Vertical and horizontal social inequality and motivation for early retirement]. / Vertikale und horizontale soziale Ungleichheit und Motivation zum vorzeitigen Erwerbsausstieg.

BACKGROUND: Over the course of the demographic transition with an aging and shrinking work force, work participation of older employees becomes more and more important. Earlier investigations found social groups to be different in work-related and individual aspects, which were shown to be associated with motivation for early retirement. OBJECTIVE: The aim of the study was to investigate the differences between older employees from distinct social groups in the motivation and determinants for early retirement. MATERIAL AND METHODS: Within the framework of the prospective lidA cohort study ( www.lida-studie.de ) socially insured employees born in 1959 and 1965 were asked about work, health and work participation. Based on data from the 3961 participants who were employed at the time of both study waves (2011, 2014), associations between variables of horizontal (gender, migration background) and vertical (education) social inequality and motivation for early retirement were analyzed with multiple logistic regression and interaction analysis. RESULTS: There was an educational gradient regarding the motivation to retire in the expected direction. The wish to retire before the age of 65 years was less common in male than in female older employees. Employees with a lower level of education and with a first generation migration background wished to retire early significantly less frequently than those without a migration background. Besides the interaction between migration background and education there were no further significant moderating effects of work-related or non-work-related variables on the association of social variables and the wish to retire early. CONCLUSION: According to the results there are differences between social groups of older employees in the motivation to retire early. The reasons and the final realization still have to be investigated. As a result, consequences for companies and politics with respect to the preservation of the work force can arise.

Work overcommitment: Is it a trait or a state?

PURPOSE: Effort-reward imbalance (ERI) is a well-tested work-related stress model with three components, the two extrinsic components "efforts" and "rewards" and the one intrinsic component "overcommitment". While an imbalance between "efforts" and "rewards" leads to strain reactions, "work-related overcommitment" (OC) has been described as a personal characteristic with a set of attitudes, behaviours, and emotions reflecting excessive striving combined with a strong desire for approval. However, the question whether OC is a personality trait or a response pattern sensitive to changes in the work context (state) is still open. METHODS: 2940 Swedish industrial employees were included in this longitudinal analysis of the WOLF-Norrland data over 5 years. A change of OC index or its subscales were regressed against a change of freedom of choice at work, extra work, and ERI adjusted for age, sex, and education. RESULTS: While OC was insensitive to changes in freedom of choice at work and extra work, it was clearly associated with changes of work-related stress over time. Three of four OC subscales exhibited statistically significant associations with ERI. CONCLUSIONS: For the first time, we studied fundamental characteristics of OC as an independent personality variable (trait) or an outcome variable subject to changes in the work environment (state). The association between external ERI and OC over time supports our hypothesis of OC being a state. Further investigations are needed to establish OC as a trait or a state.

Age-related associations between work over-commitment and zest for work among Swedish employees from a cross-sectional and longitudinal perspective.

BACKGROUND: In aging societies, zest for work may be pivotal when deciding to stay occupationally active longer. Psychosocial work stress is a prevalent public health problem and may have an impact on zest for work. Work over-commitment (WOC) is a personal coping strategy for work stress with excessive striving and a health risk. However, the long-term effect of WOC on zest for work is poorly understood. OBJECTIVE: To investigate the age-related associations of work over-commitment with zest for work. METHODS: During 1996-1998 and 2000-2003, predominantly industrial workers (n = 2940) participated in the WOLF-Norrland study and responded to a questionnaire referring to socio-demographics, WOC, zest for work, effort-reward imbalance proxies, and mental health. Age-adjusted multiple logistic regressions were performed with original and imputed datasets. RESULTS: Cross-sectionally, work overcommitted middle-aged employees had an increased prevalence of poor zest for work compared to their contemporaries without WOC (OR: 3.74 [95%-CI 2.19; 6.40]). However, in a longitudinal analysis associations between onset of 'poor zest for work' and the WOC subscales 'need for approval' (OR: 3.29 [95%-CI 1.04; 10.37]) and 'inability to withdraw from work' (OR: 5.14 [95%-CI 1.32; 20.03]) were observed. CONCLUSION: The longitudinal findings among older employees could be relevant regarding the expected need to remain occupationally active longer.

Are status inconsistency, work stress and work-family conflict associated with depressive symptoms? Testing prospective evidence in the lidA study.

BACKGROUND: Depressive symptoms are common and economically relevant. Women suffer more often than men do. We analyze associations between social status inconsistency, psychosocial factors, and depressive symptoms stratified by gender. METHODS: In the present study, 3340 employees of two age cohorts (1959, 1965) working in two waves (2011, 2014) of the prospective German lidA-study and who gave written consent to link register data regarding their employment histories were included. Gender-specific influences of social status inconsistency (deviation of observed income from expected average income based on acquired education) on depressive symptoms and mediation of these associations by work stress in terms of effort-reward-imbalance (ERI) and work-family-conflict (WFC) were analyzed with confirmatory cross-lagged path models. RESULTS: Among men, consistent status (i.e., average income in a specific educational group) increased the frequency of depressive symptoms. No association between negative SSI (i.e., income below the average income given a specific educational attainment) or positive SSI (i.e., income above the average income given a specific educational attainment) and depressive symptoms was observed among men or women. ERI and WFC were longitudinally associated with the outcome and differed slightly regarding gender, i.e., showing stronger effects of ERI for women and of WFC for men. Mediation of the association between social status and depressive symptoms was observed for men and for consistent status (path: consistent status → ERI → depressive symptoms) but not for SSI. CONCLUSIONS: ERI and WFC increase the risk of future episodes with depressive symptoms in men and in women irrespective of SSI, occupational position, full- or part-time work, regional factors or individual characteristics.

[Occupational gratification crisis and sickness absence in Germany: Cross-sectional results from the lidA-study]. / Berufliche Gratifikationskrisen und Arbeitsunfähigkeit in Deutschland : Querschnittsergebnisse aus der lidA(leben in der Arbeit)-Studie.

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.

Cut-off values for the applied version of the Beck Depression Inventory in a general working population.

BACKGROUND: The Beck Depression Inventory (BDI) for the assessment of depressive symptoms is well established in clinical settings. An applied version (BDI-V) was previously developed in German for use within epidemiologic studies. The current study analyses the association between this applied version of the BDI and different measures of functioning. The aim is to determine BDI-V cut-off values when used in a population of employees. METHODS: The study included 6339 employees of the first wave of a German cohort study on work, age, health and work participation. Depressive symptoms were assessed by an applied version of the BDI-V. Data on functioning were obtained from personal interviews. The determination of cut-off values is achieved with the min-max principle for classification applied to receiver operating characteristic (ROC) curves. RESULTS: The min-max principle points to a BDI-V cut-off between 20 and 24 for male and between 23 and 28 for female respondents. The corresponding sensitivities range between 0.64 and 0.75 for males and between 0.59 and 0.74 for females. Specificities range between 0.64 and 0.75 for males and between 0.60 and 0.74 for females. Female respondents have higher BDI-V cut-offs for all criteria. CONCLUSIONS: The range of values is lower than a recommendation in a former study. In addition to this, the values differ for gender. The current analyses focus on an easier-to-use version of the BDI formerly applied for epidemiologic studies. The determination of cut-off values is based on criteria which are indicators for impairment in (work) functioning in a population of employees. Therefore, grouping of individuals according to the reported cut-off values is guided by the relevance of these scores for occupational functioning.

Work-family conflict as a mediator in the association between work stress and depressive symptoms: cross-sectional evidence from the German lidA-cohort study.

OBJECTIVE: The demographic change leads to a shrinking German work force. Depressive symptoms cause many days absent at work, loss of productivity and early retirement. Therefore, pathways for prevention of depressive symptoms are important for the maintenance of global competitiveness. We investigated the role of work-family conflict (WFC) in the well-known association between work stress and depressive symptoms. METHODS: A total of 6,339 employees subject to social insurance, born in 1959 or 1965 and randomly drawn from 222 sample points in Germany participated in the first wave of the leben in der Arbeit-study. In the analysis, 5,906 study subjects working in full-time or part-time positions were included. Work stress was measured by effort-reward imbalance ratio, depressive symptoms by the applied Becks depression inventory (BDI-V) and WFC by items of the Copenhagen Psychosocial Questionnaire (COPSOQ)-scale. Multiple linear regression analysis adjusted for age, education, negative affectivity (PANAS), overcommitment and number of children was performed. Mediation was defined according to the criteria of Baron and Kenny. RESULTS: Work stress was significantly associated with depressive symptoms (BDI-V) in all full-time [ß1female = 6.61 (95 % CI 3.95-9.27); ß1male = 8.02 (95 % CI 5.94-10.09)] and female part-time employees [ß2female = 4.87 (95 % CI 2.16-7.59)]. When controlling for WFC effect, estimates became smaller in men and were even halved in women. WFC was also significantly associated with work stress and depressive symptoms: All criteria for partial mediation between work stress and depressiveness were fulfilled. CONCLUSIONS: Prevention of WFC may help to reduce days absent at work and early retirement due to work stress-related depressive symptoms in middle-aged women and men.

Are effort-reward imbalance and social isolation mediating the association between education and depressiveness? Baseline findings from the lidA(§)-study.

OBJECTIVES: To investigate multiple mediations of the association between education and depressive symptoms (BDI-V) by work-related stress (ERI) and social isolation, the regional variation of the first mediation and a potential moderating effect of regional unemployment rate. METHODS: 6339 employees born in 1959 and 1965 were randomly recruited from 222 sample points in a German cohort study on work, age, health and work participation. A multilevel model of moderated lower-level mediation was used to investigate the confirmatory research question. Multiple mediations were tested corresponding to Baron and Kenny. These analyses were stratified for age and adjusted for sex, negative affectivity and overcommitment. RESULTS: In the association between education and depressive symptoms, indirect effects of work-related stress and social isolation were significant in both age cohorts whereas a direct association was observable in the younger cohort, only. The significant regional variation in the association between work-related stress and depressive symptoms was not statistically explained by regional unemployment rate. CONCLUSIONS: Our findings point out that work-related stress and social isolation play an intermediary role between education and depressive symptoms in middle-aged employees.
