Exploring Work-Related Causal Attributions of Common Mental Disorders

Mental disorders in judicial workers: analysis of sickness absence in a cohort study

OBJECTIVE

To analyze risk factors for sickness absence due to mental disorders among judicial workers in Bahia, Brazil.

METHODS

Retrospective cohort with follow-up from 2011 to 2016 with 2,660 workers of a judicial sector in Bahia, Brazil. The main outcome measures were survival curves estimated for the independent variables using the Kaplan-Meier product limit estimator and risk factors for the first episode of sickness absence calculated based on the Cox regression model.

RESULTS

The survival estimate of the population of this study for the event was 0.90 and from the Cox model the risk factors for the first episode of sickness absence due to mental disorders were: female (HR = 1.81), occupation of magistrate (HR = 1.80), and age over 30 years old (HR = 1.84). In addition, the risk for new cases of sickness absence among women reached 4.0 times the risk for men, in 2015. The estimated relative risks of sickness absence and the observed survival reduction behavior over time add information to the literature on sociodemographic and occupational factors associated with sickness absence due to mental disorders in the public sector.

CONCLUSION

These results highlight the need for further research to more precisely identify vulnerable groups at risk of preventable mental health-related sickness absence in the workplace, better identify the workplace organizational factors that contribute to these disorders as well as studies on the effectiveness of workplace interventions to improve mental health among judicial and other public sectors workers.

Validation of the Work Disability Diagnosis Interview for Musculoskeletal and Mental Disorders

Purpose The Work Disability Diagnosis Interview (WoDDI) consists of a semi-structured interview designed to help clinicians systematically identify the factors contributing to a work disability. The aim was to validate two versions of the WoDDI (construct validity, internal consistency, interrater reliability) developed for individuals absent from work due to a musculoskeletal disorder (MSD) or common mental disorder (CMD). Methods A convenience sample of workers absent from work for at least three months due to an MSD or a CMD and enrolled in a rehabilitation program was recruited. To assess interrater reliability for the MSD and CMD versions, six occupational therapists by sub-group scored the WoDDI based on case histories. Results A total of 290 male and female workers (140 MSD, 150 CMD) were recruited. Exploratory factor analysis revealed similar dimensions in both versions, specifically, illness representation, clinical judgment of the complexity of the medical condition, and high level of work demands. It allowed items to be reduced by approximately 20 and 40% respectively for the CMD and MSD versions. Internal consistency (Cronbach's alpha) varied from 0.40 to 0.75 and 0.75 to 0.80 for the CMD and MSD versions respectively, while interrater reliability (Cohen's kappa coefficients) varied from 0.51 to 0.57 and 0.27 to 0.44 for the two versions respectively. Conclusion Despite some limitations, the WoDDI's factors correspond to those in the current scientific literature. The varying results for internal consistency suggest limitations mainly for the CMD version. Interrater reliability was found overall to be fair. The next step will be to revise and retest this version.

The Occupational Depression Inventory: A new tool for clinicians and epidemiologists

BACKGROUND

Depressive symptoms induced by insurmountable job stress and sick leave for mental health reasons have become a focal concern among occupational health specialists. The present study introduces the Occupational Depression Inventory (ODI), a measure designed to quantify the severity of work-attributed depressive symptoms and establish provisional diagnoses of job-ascribed depression. The ODI comprises nine symptom items and a subsidiary question assessing turnover intention.

METHODS

A total of 2254 employed individuals were recruited in the U.S., New Zealand, and France. We examined the psychometric and structural properties of the ODI as well as the nomological network of work-attributed depressive symptoms. We adopted an approach centered on exploratory structural equation modeling (ESEM) bifactor analysis. We developed a diagnostic algorithm for identifying likely cases of job-ascribed depression (SPSS syntax provided).

RESULTS

The ODI showed strong reliability and high factorial validity. ESEM bifactor analysis indicated that, as intended, the ODI can be used as a unidimensional measure (Explained Common Variance = 0.891). Work-attributed depressive symptoms correlated in the expected direction with our other variables of interest-e.g., job satisfaction, general health status-and were markedly associated with turnover intention. Of our 2254 participants, 7.6% (n = 172) met the criteria for a provisional diagnosis of job-ascribed depression.

CONCLUSIONS

This study suggests that the ODI constitutes a sound measure of work-attributed depressive symptoms. The ODI may help occupational health researchers and practitioners identify, track, and treat job-ascribed depression more effectively. ODI-based research may contribute to informing occupational health policies and regulations in the future.

Development and Construct Validity of the Work Instability Scale for People With Common Mental Disorders in a Sample of Depressed and Anxious Workers: A Rasch Analysis

BACKGROUND

Sick leave due to common mental disorders, encompassing depression and anxiety disorders, is high. Capturing early signs of reduced function could aid adjustments of work tasks and environment and, thus, endorse a pro-active approach to occupational and health care interventions to prevent long-term sick-leave spells. However, few measurements exist to identify early signs of imbalance, and none that is illness-specific. The aim of this study was to develop a work instability scale for people with common mental disorders and to test the fundamental psychometric properties of the scale.

METHODS

Participants were working adults 18-65 years old with depression or anxiety. The scale development started with qualitative interviews (n = 27) which informed the drafting of a dichotomous, self-report questionnaire. Cognitive debriefing (n = 12) was used to check face validity and modify the draft. Internal construct validity of the draft was tested using Rasch analysis (n = 128). The work ability index was used as a comparator measure.

RESULTS

The initial 63-item draft showed poor fit to Rasch model expectations. Items displaying poor fit or local response dependency were stepwise removed, resulting in a unidimensional 34-item scale fitting the model expectations, and with no differential item functioning. Person-item threshold distribution showed that the scale is better suited to measure low to moderate work instability, than to measure high instability. Correlations between the newly developed scale and the work ability index showed a significant, moderately strong correlation.

CONCLUSIONS

In the initial target sample, the 34-item scale showed acceptable fundamental properties and internal construct validity. Further validation of the scale in a larger sample, including tests for external validity, is warranted.

Exploring the service and knowledge gap between rehabilitation professionals and employers in the return-to-work process of people with mental health problems in Sweden

BACKGROUND

Research is needed on how to optimize the return-to-work process for persons with mental health problems.

OBJECTIVE

To develop a model that explains how employer and rehabilitation professional mental health literacy may influence strategies used in the return-to-work of persons with mental health problems.

METHODS

A grounded theory study design was used to collect and analyse interview data from 23 employers and 22 rehabilitation professionals.

RESULTS

The analysis resulted in four categories, illustrated in a conceptual process model: 1) seeing mental health problems through past experiences; 2) separating understandable and incomprehensible mental health problems; 3) balancing safeguarding one's personal interest with providing adequate support; and 4) facing conflicts and uncertainty in employee/service user return-to-work. A positional map of employer/rehabilitation types was created based on level of negative attitudes and uncertainty in supporting employees/service users and the employer in relation to the level of comprehensive understanding of mental health problems.

CONCLUSIONS

Professional mental health literacy needs to be increased. Interventions need to be developed that provide employers with targeted support and knowledge in mental health literacy. Education on how to prevent and detect common mental health problems in the workplace is needed.

A New Mental Health Mobile App for Well-Being and Stress Reduction in Working Women: Randomized Controlled Trial

BACKGROUND

Although the availability and use of mobile mental health apps has grown exponentially in recent years, little data are available regarding their efficacy.

OBJECTIVE

This study aimed to evaluate the effectiveness of an app developed to promote stress management and well-being among working women compared with a control app.

METHODS

Female employees at a private hospital were invited to participate in the study via mailing lists and intranet ads. A total of 653 individuals self-enrolled through the website. Eligible participants were randomized between control (n=240) and intervention (n=250) groups. The well-being mobile app provides an 8-week program with 4 classes per week (including a brief theoretical portion and a 15-min guided practice). The active control app also provided 4 assessments per week that encouraged participants to self-observe how they were feeling for 20 min. We also used the app to conduct Web-based questionnaires (10-item Perceived Stress Scale and 5-item World Health Organization Well-Being Index) and ask specific questions to assess subjective levels of stress and well-being at baseline (t₁), midintervention (t₄=4 weeks after t₁) and postintervention (t₈=8 weeks after t₁). Both apps were fully automated without any human involvement. Outcomes from the control and intervention conditions at the 3 time points were analyzed using a repeated measures analysis of variance.

RESULTS

Among the randomized participants (n=490), 185 participants were excluded at the 4-week follow-up and another 79 at the 8-week follow-up because of noncompliance with the experimental protocol. Participants who did not complete t₄ and t₈ assessments were equally distributed between groups (t₄: control group=34.6% [83/240] and intervention group=40.8% [102/250]; P=.16; t₈: control group=29.9% [47/157] and intervention group=21.6% [32/148]; P=.10). Both groups showed a significant increase in general well-being as a function of time (F_2,426=5.27; P=.006), but only the intervention group presented a significant increase in work-related well-being (F_2,426=8.92; P<.001), as well as a significant reduction in work-related and overall stress (F_2,426=5.50; P=.004 and F_2,426=8.59; P<.001, respectively).

CONCLUSIONS

The well-being mobile app was effective in reducing employee stress and improving well-being.

Determinants of Sickness Absence and Return to Work Among Employees with Common Mental Disorders: A Scoping Review

Purpose To present an overview of the existing evidence on prognostic factors of (recurrent) sickness absence (SA) and return to work (RTW) among workers with a common mental disorder (CMD). This scoping review provides information about determinants for SA and RTW, which could be used to develop better interventions aimed at the prevention of SA and promotion of RTW among workers with a CMD. Methods Relevant articles were identified in PubMed, Embase, PsycINFO, PSYNDEX, and SINGLE up to October 2016. In order to be included, studies should provide insight into prognostic factors of SA or RTW of workers with a CMD. We classified all factors according to the domains of the International Classification of Functioning, Disability and Health. Results Our searches identified 2447 possible relevant articles, of which 71 were included for data extraction. There is consistent evidence in ≥3 studies that previous episodes of CMD, higher symptom severity, previous absenteeism, co-morbidity, high job demands, low job control, high job strain, female gender, lower educational level, smoking behavior, and low perceived general health are predictors of SA in people with CMDs. Earlier RTW is consistently predicted by lower symptom severity, having no previous absenteeism, younger age, and positive expectations concerning sick-leave duration or RTW. Conclusions The amount of research on determinants for SA and RTW in workers with CMD has increased dramatically in recent years, although most studies are from the Netherlands and Scandinavia. There are some research gaps identified in this scoping review that need further attention in primary and secondary studies. Based on the summary of the evidence, we provide guidance for policy, practice and research.

Evaluating the Impacts of Health, Social Network and Capital on Craft Efficiency and Productivity: A Case Study of Construction Workers in China

The construction industry has been recognized, for many years, as among those having a high likelihood of accidents, injuries and occupational illnesses. Such risks of construction workers can lead to low productivity and social problems. As a result, construction workers’ well-being should be highly addressed to improve construction workers’ efficiency and productivity. Meanwhile, the social support from a social network and capital (SNC) of construction workers has been considered as an effective approach to promote construction workers’ physical and mental health (P&M health), as well as their work efficiency and productivity. Based on a comprehensive literature review, a conceptual model, which aims to improve construction workers’ efficiency and productivity from the perspective of health and SNC, was proposed. A questionnaire survey was conducted to investigate the construction workers’ health, SNC and work efficiency and productivity in Nanjing, China. A structural equation model (SEM) was employed to test the three hypothetical relationships among construction workers’ P&M health, SNC and work efficiency and productivity. The results indicated that the direct impacts from construction workers’ P&M health on work efficiency and productivity were more significant than that from the SNC. In addition, the construction workers’ social capital and the network can indirectly influence the work efficiency and productivity by affecting the construction workers’ P&M health. Therefore, strategies for enhancing construction workers’ efficiency and productivity were proposed. Furthermore, many useable suggestions can be drawn from the research findings from the perspective of a government. The identified indicators and relationships would contribute to the construction work efficiency and productivity assessment and health management from the perspective of the construction workers.

Prevalence of work-related common psychiatric disorders in primary care: The French Héraclès study

General practitioners (GP), on the frontline for individuals with mental health problems, often deal with work-related common psychiatric disorders. We aimed to determine the prevalence of work-related common psychiatric disorders in general practice and associated patients' and GPs' characteristics. HERACLES, a cross-sectional study among 2019 working patients of 121 GPs in the Nord - Pas-de-Calais region in France. Common psychiatric disorders were assessed using the MINI International Neuropsychiatric Interview, patient-perceived psychological distress and GP-diagnosed psychiatric disorders. The work-relatedness of common psychiatric disorders was ascertained by the GP and/or the patient. Prevalence rates adjusted on age were calculated by sex and associated characteristics were ascertained using multilevel Poisson regression models. The prevalence of work-related common psychiatric disorders ascertained using the MINI was estimated at 25.6% [23.7-27.5], 24.5% [22.6-26.4] for self-reported psychological distress and 25.8% [23.9-27.7] for GP-diagnosed psychiatric disorders. Age, history of psychiatric disorders, consultation for psychological purpose and GP's characteristics were associated with MINI-identified psychiatric disorders. The prevalence of work-related common psychiatric disorders among working adults seen in general practice is high but further studies are needed to support this results.

Integrated mental health care and vocational rehabilitation to improve return to work rates for people on sick leave because of exhaustion disorder, adjustment disorder, and distress (the Danish IBBIS trial): study protocol for a randomized controlled trial

BACKGROUND

Common mental disorders are important contributors to the global burden of disease and cause negative effects on both the individual and society. Stress-related disorders influence the individual's workability and cause early retirement pensions in Denmark. There is no clear evidence that mental health care alone will provide sufficient support for vocational recovery for this group. Integrated vocational and health care services have shown good effects on return to work in other similar welfare contexts. The purpose of the Danish IBBIS (Integreret Behandlings- og BeskæftigelsesIndsats til Sygemeldte) study is to examine the efficacy of (1) a stepped mental health care intervention with individual stress coaching and/or group-based MBSR and (2) an integrated stepped mental health care with individual stress coaching and/or group-based MBSR and vocational rehabilitation intervention for people on sick leave because of exhaustion disorder, adjustment disorder or distress in Denmark.

METHOD/DESIGN

This three-armed, parallel-group, randomized superiority trial is set up to investigate the effectiveness of a stepped mental health care intervention and an integrated mental health care and vocational rehabilitation intervention for people on sick leave because of exhaustion disorder, adjustment disorder or distress in Denmark. The trial has an investigator-initiated multicenter design. Six hundred and three patients will be recruited from Danish vocational rehabilitation centers in four municipalities and randomly assigned into three groups: (1) IBBIS mental health care integrated with IBBIS vocational rehabilitation, (2) IBBIS mental health care and standard vocational rehabilitation, and (3) standard mental health care and standard vocational rehabilitation. The primary outcome is register-based return to work at 12 months. The secondary outcome measures are self-assessed level of depression (BDI), anxiety (BAI), distress symptoms (4DSQ), work- and social functioning (WSAS), and register-based recurrent sickness absence.

DISCUSSION

This study will contribute with knowledge on the consequence of the current organizational separation of health care interventions and vocational rehabilitation regarding the individual's process of returning to work after sick leave because of exhaustion disorder, adjustment disorder or distress. If the effect on return to work, symptom level, and recurrent sick leave is different in the intervention groups, this study can contribute with new knowledge on shared care models and the potential for preventing deterioration in stress symptoms, prolonged sick leave, and recurrent sick leave.

TRIAL REGISTRATION

ClinicalTrials.gov, registration number: NCT02885519 . Retrospectively registered on 15 August 2016). Participants have been included in the IBBIS trial for distress, adjustment disorder and exhaustion disorder since April 2016.

Stratégies de retour au travail d’employés ayant fait l’expérience d’une dépression : perspectives des employeurs et des cadres des ressources humaines

La dépression majeure est l’une des premières causes d’incapacité au travail dans le monde et a de nombreuses conséquences tant sur l’employé concerné qu’auprès des acteurs du milieu de travail.

ObjectifNous visons à documenter, selon la perspective des employeurs et des cadres des ressources humaines, les stratégies que ces acteurs préconisent dans leur organisation pour faciliter le retour au travail (RaT) d’employés en absence maladie due à une dépression.

MéthodeDeux cent dix-neuf employeurs et cadres de ressources humaines (n = 219) ont accepté de répondre à une entrevue semi-structurée téléphonique. La question abordée dans cet article était : « Selon vous, quelles sont les stratégies les plus efficaces pour aider un employé ayant reçu un diagnostic de dépression à retourner au travail ? » La codification duverbatima été effectuée à partir d’études empiriques et de théories existantes.

RésultatsTrente-quatre (34) stratégies réparties sur six grands principes ont émergé : 1) Contact avec l’employé en absence maladie (10 stratégies) ; 2) Évaluation et planification du RaT sans précipitation (6) ; 3) Formation des gestionnaires et du collectif de travail à la problématique de la santé mentale au travail (4) ; 4) Concertation des acteurs clés du RaT (4) ; 5) RaT progressif avec aménagements (4) ; 6) Suivi de la santé de l’employé et de son travail (6).

ConclusionCes principes articulés autour de 34 stratégies du RaT vont au-delà d’un processus étapiste de nature chronologique. Articulés dans un programme de RaT, ils devront être testés afin d’évaluer leurs retombées dans les organisations, notamment sur la gestion de l’incapacité au travail.
