Return-to-Work Self-Efficacy and Actual Return to Work Among Long-Term Sick-Listed Employees

Prognostic factors for return to work of employees with common mental disorders: a meta-analysis of cohort studies

PURPOSE

To examine prognostic factors for return to work (RTW) of employees with common mental disorders (CMDs).

METHODS

A systematic review and meta-analysis were performed using data from 18 published cohort studies with 24,579 participants. The studies were identified from MEDLINE/PubMed, PsycINFO, EMBASE, SocINDEX, and Human resource management databases from 1995 to 2016. Two authors independently screened selected studies and assessed the quality of the studies as well as the extracted data.

RESULTS

We screened 7755 abstracts, from which 211 full text articles were reviewed. Eighteen cohort studies met the inclusion criteria and were included in the analysis. Significant prognostic factors for RTW included age, contact with medical specialists, RTW-self-efficacy, and work ability. The pooled hazard ratios and 95% confidence interval (CI) for age, RTW-SE, contact with medical specialists, and high work ability/low work demands in relation to RTW were 0.77 (95% CI 0.65-0.88), 1.79 (95% CI 1.24-2.33), 0.64 (95% CI 0.49-0.80) and 1.08 (95% CI 1.06-1.11), respectively.

CONCLUSIONS

Self-efficacy (SE) is a key factor in the enhancement of work ability and RTW. Improving employee's SE and collaborating with employers to enhance work ability may help to facilitate RTW. As the RTW process is complex, exploring theoretical frameworks for RTW in individuals with a CMD is also needed.

Employment Status of Depressed Individuals in an 11-Year Follow-up: Results From the Finnish Health 2011 Survey

OBJECTIVES

The aim of this study was to describe the employment and mental health status of persons with depressive disorders after an 11-year follow-up, and identify individual and work-related factors that predict adverse outcomes.

METHODS

Two nationally representative health surveys, Health 2000 and its follow-up, Health 2011 were used, and persons with depressive disorders at baseline (n = 275) were re-interviewed after 11 years.

RESULTS

Information on employment status was available for all 263 participants in 2011. About 15.7% had been granted disability pension by 2011, while 55.5% were employed and 18.2% on old-age pension. High job control was the only statistically significant predictor of lower probability of disability pension (adjusted odds ratio 0.42, 95% confidence interval [95% CI] 0.23 to 0.77). Being unmarried (adjusted odds ratio 2.99, 95% CI 1.19 to 7.52) was associated with persistent depressive disorder.

CONCLUSIONS

Job control emerged as an important predictor of long-term employment outcomes among depressed individuals.

Brazilian cross-cultural adaptation of "Return-to-work self-efficacy" questionnaire

OBJECTIVE

To describe the translation and early stages of cross-cultural adaptation of the questionnaire Verwachtingen over werken (or "Return-to-work self-efficacy") for workers in sick leave due to mental disorders, from the original in Dutch to the Brazilian Portuguese language.

METHODS

A panel gathering experts was formed to determine the questionnaire conceptual and item equivalence. For semantic equivalence, the Dutch-Portuguese Brazilian translations were consolidated and consensus meetings were held to structure versions of the instrument. Each version was back-translated from Brazilian Portuguese to Dutch and evaluated by one of the authors of the original version. The final version was submitted to two pre-tests for operational equivalence.

RESULTS

The original questionnaire in Dutch was translated twice to Brazilian Portuguese. During the process, four consensus meetings of the experts' panel were performed to create the versions. Each version was back-translated to Dutch. One of the authors of the original questionnaire performed an evaluation on the first three versions until the definition of the final one, which was titled Expectativas sobre o trabalho (Expectations about work). Pre-tests' participants did not reported problems to fill the questionnaire.

CONCLUSIONS

Results indicate that the Brazilian Portuguese cross-culturally adapted version maintains the original meaning of the questionnaire, while including characteristics peculiar to the Brazilian reality. Measurement and functional equivalence of this version must still be evaluated before its application can be recommended for workers who have been absent from work due to mental disorders.

Interventions for enhancing return to work in individuals with a common mental illness: systematic review and meta-analysis of randomized controlled trials

Common mental disorders (CMDs) are highly prevalent in the working population, and are associated with long-term sickness absence and disability. Workers on sick leave with CMDs would benefit from interventions that enable them to successfully return to work (RTW). However, the effectiveness of RTW interventions for workers with a CMD is not well studied. The objective of this review is to assess the effectiveness of existing workplace and clinical interventions that were aimed at enhancing RTW. A systematic review of studies of interventions for improving RTW in workers with a CMD was conducted. The main outcomes were proportion of RTW and sick-leave duration until RTW. Randomized controlled trials (RCTs) were identified from Medline/PubMed, PsycINFO, EMBASE, SocINDEX, and Human resource and management databases from January 1995 to 2016. Two authors independently selected studies, assessed risk of bias and extracted data. We pooled studies that we deemed sufficiently homogeneous in different comparison groups and assessed the overall quality of the evidence. We reviewed 2347 abstracts from which 136 full-text articles were reviewed and 16 RCTs were included in the analysis. Combined results from these studies suggested that the available interventions did not lead to improved RTW rates over the control group [pooled risk ratio 1.05, 95% confidence interval (CI) 0.97-1.12], but reduced the number of sick-leave days in the intervention group compared to the control group, with a mean difference of -13.38 days (95% CI -24.07 to -2.69).

Cancer survivors' perspectives and experiences regarding behavioral determinants of return to work and continuation of work

PURPOSE

Supportive interventions to enhance return to work (RTW) in cancer survivors hardly showed positive effects so far. Behavioral determinants might have to be considered in the development of interventions to achieve sustained employability. This study aimed to explore cancer survivors' perspectives and experiences regarding behavioral determinants of RTW and continuation of work.

MATERIALS AND METHODS

In this qualitative study, semi-structured telephone interviews were held with 28 cancer survivors. All participants were at working age, 1-2 years after diagnosis and employed at time of diagnosis. Thematic content analysis was performed.

RESULTS

Work turned out to be a meaningful aspect of cancer survivors' life, and most participants reported a positive attitude towards their job. Social support to RTW or to continue working was mainly received from family and friends, but pressure to RTW from the occupational physician was also experienced. Changes in expectations regarding work ability from negative to positive during the treatment process were observed. Those who applied active coping mechanisms felt equipped to deal with difficulties regarding work.

CONCLUSIONS

Behavioral determinants should be taken into account in the development of future interventions to support cancer survivors' RTW. However, the causal relationship still has to be determined. Implications for rehabilitation Factors influencing occupational motivation among cancer survivors need to be understood in more detail. Previous studies in non-cancer populations have demonstrated that behavioral determinants, such as a positive attitude towards work, high social support and self-efficacy may increase return to work rates or shorten the time to return to work. Addressing behavioral determinants in future development of work-related interventions for cancer survivors is essential in achieving sustained employability.

Validation of the Patient Health Questionnaire-9 for Major Depressive Disorder in the Occupational Health Setting

Purpose Because of the increased risk of long-term sickness leave for employees with a major depressive disorder (MDD), it is important for occupational health professionals to recognize depression in a timely manner. The Patient Health Questionnaire-9 (PHQ-9) has proven to be a reliable and valid instrument for screening MDD, but has not been validated in the occupational health setting. The aim of this study was to validate the PHQ-9 for MDD within a population of employees on sickness leave by using the MINI-International Neuropsychiatric Interview (MINI) as a gold standard. Methods Participants were recruited in collaboration with the occupational health service. The study sample consisted of 170 employees on sickness leave between 4 and 26 weeks who completed the PHQ-9 and were evaluated with the MINI by telephone. Sensitivity, specificity, positive and negative predictive value, efficiency and 95 % confidence intervals (95 % CIs) were calculated for all possible cut-off values. A receiver operator characteristics (ROC) analysis was computed for PHQ-9 score versus the MINI. Results The optimal cut-off value of the PHQ-9 was 10. This resulted in a sensitivity of 86.1 % [95 % CI (69.7-94.8)] and a specificity of 78.4 % [95 % CI (70.2-84.8)]. Based on the ROC analysis, the area under the curve for the PHQ-9 was 0.90 [SE = 0.02; 95 % CI (0.85-0.94)]. Conclusion The PHQ-9 shows good sensitivity and specificity as a screener for MDD within a population of employees on sickness leave.

Improving a web-based employability intervention for work-disabled employees: results of a pilot economic evaluation

Purpose The purpose of this study is to improve web-based employability interventions for employees with work-related health problems for both intervention content and study design by means of a pilot economic evaluation. Methods Uptake rate analysis for the intervention elements, cost effectiveness, cost utility and subgroup analyses were conducted to identify potential content-related intervention improvements. Differences in work ability and quality-adjusted life years and overall contribution of resource items to the total costs were assessed. These were used to guide study design improvements. Results Sixty-three participants were a-select allocated to either the intervention (n = 29) or the control (n = 34) group. Uptake regarding the intervention elements ranged between 3% and 70%. Cost-effectiveness and cost-utility analyses resulted in negative effects although higher total costs. Incremental effects were marginal (work ability -0.51; QALY -0.01). Conclusions The web-based tool to enhance employability among work disabled employees requires improvements regarding targeting and intensity; outcome measures selected and collection of cost data. With respect to the studies of disability and rehabilitation, the findings and methods presented in this pilot economic evaluation could guide the assessment of future assistive "e-health" technologies. IMPLICATIONS FOR REHABILITATION The methods presented in this pilot economic evaluation have large potentials to guide the assessment of future assistive e-health technologies addressing work-disabilities. The findings show that the web-based tool requires content related improvements with respect to targeting and intensity to enhance employability among work disabled employees. The findings show that the web-based tool would benefit from improvements related to the study design by more adequately selecting and collecting both outcome measures and cost data. The burden attributable to large-scale studies and implementation issues were prevented as the outcomes of the pilot economic evaluation did not support the implementation of the web-based tool.

Predictors of self-efficacy in women on long-term sick leave

Self-efficacy has been shown to be related to sick leave and to be a predictor of return to work after sickness absence. The aim of this study was to investigate whether factors related to sick leave predict self-efficacy in women on long-term sick leave because of pain and/or mental illness. This cross-sectional study uses baseline data from 337 Swedish women with pain and/or mental illness. All included women took part in vocational rehabilitation. Data were collected through a sick leave register and a baseline questionnaire. General self-efficacy, sociodemographics, self-rated health, anxiety, depression, view of the future, and social support were measured and analyzed by univariate and multivariate linear regression analyses. The full multivariate linear regression model, which included mental health factors together with all measured factors, showed that anxiety and depression were the only predictive factors of lower self-efficacy (adjusted R2=0.46, P<0.001) and explained 46% of the variance in self-efficacy. The mean scores of general self-efficacy were low, especially in women born abroad, those with low motivation, those with uncertainties about returning to work, and women reporting distrust. Anxiety and depression are important factors to consider when targeting self-efficacy in vocational rehabilitation.

Effectiveness of a blended web-based intervention on return to work for sick-listed employees with common mental disorders: results of a cluster randomized controlled trial

Background

Common mental disorders are strongly associated with long-term sickness absence, which has negative consequences for the individual employee’s quality of life and leads to substantial costs for society. It is important to focus on return to work (RTW) during treatment of sick-listed employees with common mental disorders. Factors such as self-efficacy and the intention to resume work despite having symptoms are important in the RTW process. We developed “E-health module embedded in Collaborative Occupational health care” (ECO) as a blended Web-based intervention with 2 parts: an eHealth module (Return@Work) for the employee aimed at changing cognitions of the employee regarding RTW and a decision aid via email supporting the occupational physician with advice regarding treatment and referral options based on monitoring the employee’s progress during treatment.

Objective

This study evaluated the effect of a blended eHealth intervention (ECO) versus care as usual on time to RTW of sick-listed employees with common mental disorders.

Methods

The study was a 2-armed cluster randomized controlled trial. Employees sick-listed between 4 and 26 weeks with common mental disorder symptoms were recruited by their occupational health service or employer. The employees were followed up to 12 months. The primary outcome measures were time to first RTW (partial or full) and time to full RTW. Secondary outcomes were response and remission of the common mental disorder symptoms (self-assessed).

Results

A total of 220 employees were included: 131 participants were randomized to the ECO intervention and 89 to care as usual (CAU). The duration until first RTW differed significantly between the groups. The median duration was 77.0 (IQR 29.0-152.3) days in the CAU group and 50.0 (IQR 20.8-99.0) days in the ECO group (hazard ratio [HR] 1.390, 95% CI 1.034-1.870, P=.03). No significant difference was found for duration until full RTW. Treatment response of common mental disorder symptoms did not differ significantly between the groups, but at 9 months after baseline significantly more participants in the ECO group achieved remission than in the CAU group (OR 2.228, 95% CI 1.115-4.453, P=.02).

Conclusions

The results of this study showed that in a group of sick-listed employees with common mental disorders, applying the blended eHealth ECO intervention led to faster first RTW and more remission of common mental disorder symptoms than CAU.
