Common mental disorders and disability pension award: seven year follow-up of the HUSK study

Linking electronic mental healthcare and benefits records in South London: design, procedure and descriptive outcomes

OBJECTIVES

To describe the process and outcomes of a data linkage between electronic secondary mental healthcare records from the South London and Maudsley (SLaM) NHS Foundation Trust with benefits records from the Department for Work and Pensions (DWP). We also describe the mental health and benefit profile of patients who were successfully linked.

DESIGN

A deterministic linkage of routine records from health and welfare government service providers within a secure environment.

SETTING AND PARTICIPANTS

Adults aged≥18 years who were referred to or accessed treatment at SLaM services between January 2007 and June 2019, including those who were treated as part of Improving Access to Psychological Therapies (IAPT) services between January 2008 and June 2019 (n=448 404). Benefits data from the DWP from January 2005 to June 2020.

OUTCOME MEASURES

The linkage rate and associated sociodemographic, diagnostic and treatment factors. Recorded primary psychiatric diagnosis based on International Classification of Diseases (ICD)-10 codes and type of benefit receipt.

RESULTS

A linkage rate of 92.3% was achieved. Women, younger patients and those from ethnic minority groups were less likely to be successfully linked. Patients who had subsequently died, had a recorded primary psychiatric diagnosis, had also engaged with IAPT and had a higher number of historical postcodes available were more likely to be linked. Overall, 83% of patients received benefits at some point between 2005 and 2020. Benefit receipt across the psychiatric diagnosis spectrum was high, over 80% across most ICD-10 codes.

CONCLUSIONS

This data linkage is the first of its kind in the UK demonstrating the use of routinely collected mental health and benefits data. Benefit receipt was high among patients accessing SLaM services and varied by psychiatric diagnosis. Future areas of research are discussed, including exploring the effectiveness of interventions for helping people into work and the impact of benefit reforms.

Adverse social behaviour at work and health-related employment exit: a prospective population-based four-wave survey

BACKGROUND

The level of evidence for various aspects of adverse social behaviour (ASB) at work as risk factors for exit from employment due to health problems or diseases is inconclusive.

METHODS

We obtained data from four consecutive surveys (2006/09/13/16) of the general population of Norway. Respondents who were interviewed in two consecutive surveys and employed at the first survey time point constituted the sample (n = 17 110 observations). We investigated associations of self-reported exposure to ASB (i.e. experiencing sexual harassment, bullying or violence/threats in the first survey) and health-related employment exit (i.e. individuals reporting exit from employment due to health problems or disease between two consecutive surveys) by means of mixed-effect logistic regression.

RESULTS

The prevalence of ASB and health-related employment exit was 10.8% (n = 1853) and 2.6% (n = 440), respectively. Adjusted for age, sex, level of education, occupation and weekly work hours, sexual harassment, bullying and violence/threats were associated with an increased risk of exit from employment. The odds ratios (ORs) for the association between exposure to any of the three aspects of ASB and employment exit was 1.78 [95% confidence interval (CI) 1.33-2.38]; the estimated corresponding population attributable risk was PAR% = 7.32 [95% CI 2.67-12.27]. Further adjustment of mental distress attenuated the observed association between exposure to any ASB and exit from employment (OR = 1.45 [95% CI 1.07-1.95], i.e. a reduction of 42% in the OR).

CONCLUSIONS

ASB at work increases the risk of health-related exit from employment in the Norwegian workforce.

Onset of Work-Life Conflict Increases Risk of Subsequent Psychological Distress in the Norwegian Working Population

We aimed to assess whether the onset of work-life conflict is associated with a risk of subsequent onset of psychological distress. Respondents from a randomly drawn cohort of the general Norwegian working population were interviewed in 2009 (T1), 2013 (T2), and 2016 (T3) (gross sample n = 13,803). Participants reporting frequent work-life conflict at T1 and/or psychological distress (five-item Hopkins Symptom Checklist mean score ≥ 2) at T2 were excluded to establish a design that allowed us to study the effect of the onset of work-life conflict at T2 on psychological distress at T3. Logistic regression analysis showed that the onset of frequent work-life conflict more than doubled the risk of the onset of psychological distress at T3 (OR = 2.55; 95% CI 1.44-4.51). The analysis of the association between occasional work-life conflict and psychological distress was not conclusive (OR = 1.21; 95% CI 0.77-1.90). No differential effects of sex were observed (log likelihood ratio = 483.7, p = 0.92). The calculated population attributable risk (PAR) suggests that 12.3% (95% CI 2.84-22.9%) of psychological distress onset could be attributed to frequent work-life conflict. In conclusion, our results suggest that the onset of frequent work-life conflict has a direct effect on the future risk of developing symptoms of psychological distress in both male and female workers.

Understanding the vocational functioning of autistic employees: the role of disability and mental health

PURPOSE

Employment rates for autistic people are low, despite increasing employment-focused programmes. Given the reported complexities for autistic people in finding and keeping work and flourishing there, further exploration is needed to understand how best to help employers accommodate autistic employees.

MATERIAL AND METHODS

We assessed 88 employed autistic adults, without comorbid intellectual disability and examined whether self-reported disability and mental health symptoms were associated with two measures of vocational functioning: disability days off work and vocational disability.

RESULTS

Nearly half (47%) reported at least one disability day absence in the previous month. Autism severity and IQ were not associated with either measure of vocational functioning. Greater disability and higher mental health symptoms were associated with both types of vocational functioning. However, the associations of anxiety and stress with both vocational outcomes were attenuated to null in a multivariable model. Disability (B = 6.74, p = 0.009; B = 1.18, p < 0.001) and depression (B = 4.46, p = 0.035; B = 1.01, p = 0.049) remained independently associated with both outcomes.

CONCLUSIONS

Clinicians and vocational support programmes addressing modifiable factors may need to focus on addressing mental health comorbidities, specifically depression rather than anxiety, or core features of autism to improve vocational outcomes for autistic people. Implications for RehabilitationIndividual-level interventions that reduce disablement, particularly in social areas, and depressive symptoms as a way of reducing days off work and improving workplace activities in autistic employees are recommended.Organisations can accommodate autistic employees by encouraging use of mental health programmes or looking at how the workplace environment can be adapted to limit social disability.

Are Organizational EHealth Interventions Becoming More Effective at Addressing Employee Mental Health; A Systematic Review and Meta-Analysis (Preprint)

Background

Mental health conditions are considered the leading cause of disability, sickness absence, and long-term work incapacity. eHealth interventions provide employees with access to psychological assistance. There has been widespread implementation and provision of eHealth interventions in the workplace as an inexpensive and anonymous way of addressing common mental disorders.

Objective

This updated review aimed to synthesize the literature on the efficacy of eHealth interventions for anxiety, depression, and stress outcomes in employee samples in organizational settings and evaluate whether their effectiveness has improved over time.

Methods

Systematic searches of relevant articles published from 2004 to July 2020 of eHealth intervention trials (app- or web-based) focusing on the mental health of employees were conducted. The quality and bias of all studies were assessed. We extracted means and SDs from publications by comparing the differences in effect sizes (Hedge g) in standardized mental health outcomes. We meta-analyzed these data using a random-effects model.

Results

We identified a tripling of the body of evidence, with 75 trials available for meta-analysis from a combined sample of 14,747 articles. eHealth interventions showed small positive effects for anxiety (Hedges g=0.26, 95% CI 0.13-0.39; P<.001), depression (Hedges g=0.26, 95% CI 0.19-0.34; P<.001), and stress (Hedges g=0.25, 95% CI 0.17-0.34; P<.001) in employees’ after intervention, with similar effects seen at the medium-term follow-up. However, there was evidence of no increase in the effectiveness of these interventions over the past decade.

Conclusions

This review and meta-analysis confirmed that eHealth interventions have a small positive impact on reducing mental health symptoms in employees. Disappointingly, we found no evidence that, despite the advances in technology and the enormous resources in time, research, and finance devoted to this area for over a decade, better interventions are being produced. Hopefully, these small effect sizes do not represent optimum outcomes in organizational settings.

Access to mental healthcare in the year after first fit note: a longitudinal study of linked clinical records

OBJECTIVES

Sickness absence is strongly associated with poor mental health, and mental disorders often go untreated. In this population-based cohort study, we identified people receiving fit notes from their general practitioner (GP) and determined access to mental health treatment stratified by health complaint and demographic variables.

DESIGN

Longitudinal study of health records.

SETTING

Primary care and secondary mental health care in the borough of Lambeth, South London. Forty-five GP practices in Lambeth and the local secondary mental healthcare trust.

PARTICIPANTS

The analytical sample included 293 933 working age adults (16-60 years) registered at a Lambeth GP practice between 1 January 2014 and 30 April 2016.

PRIMARY AND SECONDARY OUTCOME MEASURES

Three indicators of mental healthcare in the year after first fit note were antidepressant prescription, contact with Improving Access to Psychological Therapy (IAPT) services and contact with secondary mental health services.

RESULTS

75% of people with an identified mental health condition at first fit note had an indicator of mental healthcare in the following year. Black Caribbean and Black African groups presenting with mental disorders were less likely to have a mental healthcare indicator compared with White British groups.

CONCLUSIONS

The majority of those with an identified mental health need receive some treatment in the year following a fit note; however, our results suggest Black African and Black Caribbean groups with an identified mental healthcare need have less complete access compared to the White British group.

Work-focused therapy for common mental disorders: A naturalistic study comparing an intervention group with a waitlist control group

BACKGROUND:

Common mental disorders (CMD) are leading causes of sickness absence. Treatments for CMD that both reduce symptoms and support work participation urgently need to be developed.

OBJECTIVE:

Determine the potential effects of work-focused therapy combining work interventions with either meta cognitive therapy or cognitive behavioural therapy (W-MCT/CBT) for patients with CMD on sick leave.

METHODS:

Naturalistic study with a quasi-experimental approach. Pre- and post-scores (return to work, symptoms, return-to-work self-efficacy, clinical recovery from depression and anxiety) were compared between the intervention group (n = 87) who received immediate treatment over an average of 10.40 sessions (SD = 3.09) and the non-randomized waitlist control group (n = 95) that had waited an average of 11.18 weeks (SD = 2.29).

RESULTS:

Significantly more patients returned fully to work in the intervention group (41.4%) than the control group (26.3%). Effect sizes for self-efficacy scores, depression and anxiety were large in the intervention group (d = 1.28, 1.01, 1.58), and significantly lower in the control group (d = 0.60, 0.14, 0.45). Significantly more patients in the treatment group than control group recovered from depression (54.1% vs. 12.8%) and anxiety (50.0% vs.10.6%).

CONCLUSIONS:

W-MCT/CBT may be an effective intervention for patients on sick leave due to CMD.

Associations between depressive complaints and indicators of labour participation among older Dutch employees: a prospective cohort study

PURPOSE

European policy measures have led to an increased net labour participation of older employees. Yet, via different routes (for instance disability schemes) employees still often leave the labour market early. Mental health may be an important factor hindering labour participation. Aims of this study are twofold: first, to examine the relationship between mental health-particularly depressive complaints-and indicators of labour participation among older employees over a 2-year follow-up period and second, to explore the impact of different work contexts when studying this relation.

METHODS

A subsample of older employees (aged > 45 years; n = 1253) from the Maastricht Cohort Study was studied. Depressive complaints were assessed using the Hospital Anxiety and Depression scale. Logistic and Cox regression analyses covered 2 years of follow-up and were also stratified for relevant work-related factors.

RESULTS

Employees with mild depressive complaints showed statistically significantly higher risks for poor mental workability (HR 2.60, 95% CI 1.14-5.92) and high psychological disengagement levels (HR 2.35, 95% CI 1.21-4.57) over time compared to employees without depressive complaints. Within various work contexts, for instance in which employees perform physically demanding work or have high psychological job demands, significantly stronger associations were found between depressive complaints and poor mental workability over time.

CONCLUSIONS

This study shows strong longitudinal associations between depressive complaints and indicators of labour participation, also within different work contexts over time. Results provide valuable input for developing preventive measure aiming to enhance sustainable labour participation of older employees.

Long-term outcomes of Prompt Mental Health Care: A randomized controlled trial

Prompt Mental Health Care (PMHC, Norwegian adaptation of Improving Access to Psychological Therapies) is found successful in alleviating symptoms of anxiety and depression. Here, we investigate whether improvement is maintained over time. A randomized controlled trial was conducted in two PMHC sites from November 2015 to August 2017, randomly assigning 681 adults with anxiety and/or mild to moderate depression (70:30 ratio: PMHC n = 463, TAU n = 218). Main outcomes were recovery rates and changes in symptoms of depression and anxiety from baseline to 12 months. Secondary outcomes were functional status, health-related quality of life, mental wellbeing and work participation. At 12 months after baseline the reliable recovery rate was 59.4% in PMHC and 36.6% in TAU, giving a between-group effect size of 0.51 (95%CI: 0.26, 0.77, p < 0.001). Differences in symptom change gave between-group effect sizes of -0.67 (95%CI: -0.99, -0.36, p < 0.001) for depression and -0.58 (95%CI: -0.91, -0.26, p < 0.001) for anxiety. PMHC was also at 12 months found more effective in improving functional status, health-related quality of life and mental wellbeing, but not work participation. In sum, substantial treatment effects of PMHC remain at 12 months follow-up, although results should be interpreted with caution due to risk of attrition bias.

The impact of the disability support pension on mental health: evidence from 14 years of an Australian cohort

OBJECTIVE

To assess the effect of the Australian Disability Support Pension (DSP) on the symptomology of depression and anxiety over and above the effects of reporting a disability itself.

METHODS

We used the Household Income Labour Dynamics in Australia (HILDA) survey from 2004 to 2017. We used fixed effects regression to understand mental health differences (using the Mental Health Inventory-5 [MHI-5]) when a person reported: i) a disability; or ii) a disability and receiving the DSP) compared to when they reported no disability. The models controlled for time-varying changes in the severity of the disability and other time-related confounders.

RESULTS

There was a 2.97-point decline (95%CI -3.26 to -2.68) in the MHI-5 when a person reported a disability compared to waves in which they reported no disability and 4.48-point decline (95%CI -5.75 to -3.22) when a person reported both a disability and being on the DSP compared to waves in which they reported neither.

CONCLUSIONS

Results suggest that accessing and being in receipt of the DSP can impact the mental health of people with disabilities. Implications for public health: Government income support policies should address the unintended adverse consequences in already vulnerable populations.

Process evaluation of Prompt Mental Health Care (PMHC): the Norwegian version of Improving Access to Psychological Therapies

BACKGROUND

Prompt Mental Health Care (PMHC) is the Norwegian adaptation of Improving Access to Psychological Therapies (IAPT). Thus far, evaluations of PMHC have mostly focused on the effectiveness, rather than on contextual and implementation processes. Therefore, the objective of this study was to do a process evaluation and examine: 1) To what extent do the services follow guidelines provided by the Norwegian Directorate of Health (NDH), 2) what the therapists experienced as important barriers and facilitators in implementing the service, and 3) client treatment satisfaction and its associations with baseline variables.

METHOD

The present study uses data from 526 clients who received PMHC treatment in the municipalities of Sandnes and Kristiansand. The therapists completed questionnaires about each client's course of treatment. We conducted semi-structured interviews with the therapists and analysed them using thematic analysis. Data from client questionnaires were used to report descriptive sample statistics including symptom severity and treatment satisfaction. Linear regression was adopted to examine the associations between client treatment satisfaction and baseline characteristics.

RESULTS

Several aspects of PMHC were implemented in line with the guidelines provided by NDH. Importantly, both services reached out to the intended target group, and could further be characterized as low-threshold with relatively short waiting times (median waiting time between initial contact and treatment start was 27 days, IQR 18-39), no waiting lists, and frequent use of self-referral (33.3%). From the client perspective, results indicated a high degree of treatment satisfaction (Mean = 3.93 (SD = .71, range 1-5)), and this was true across demographic characteristics and symptom severity at baseline (all p > .05). Most notable challenges that came forward were; the low provision of guided self-help (received by only 1.0% of clients), the lack of focus on work participation (low to some degree of focus in 70.8% among sick-listed clients), the collaboration with other services (no collaboration in 85.3% of the clients), and some aspects regarding future development of the service.

CONCLUSION

Both sites managed to implement key aspects of PMHC in line with the guidelines, but further development of the program is warranted. Discussion of challenges and future recommendations are presented.

Risk and risk factors for disability pension among patients with treatment resistant depression- a matched cohort study

BACKGROUND

Treatment resistant depression (TRD) is common among patients with depression, and is associated with clinical and functional disability. However, the risk and risk factors for being granted disability pension (DP) among patients with TRD have not been investigated.

METHODS

All antidepressant initiators in Sweden with a diagnosis of depression in specialized care were identified in nationwide registers 2006-2013 and followed regarding treatment trials. TRD was defined as the start of a third sequential trial. Patients with TRD who were not on DP (N = 3204) were matched by age, sex, history of depression, calendar year, and time for treatment start with 3204 comparators with depression and ongoing antidepressant treatment. A proportional Cox Regression was performed with DP as outcome, adjusted for various sociodemographic and clinical covariates.

RESULTS

Compared to the comparison cohort, TRD was associated with a doubled risk for all-cause DP (aHR 2.07; 95%CI 1.83-2.35), DP due to depression (2.28; 1.82-2.85) and to any mental disorder (2.24; 1.95-2.57) but not due to somatic diagnoses (1.25; 0.84-1.86). Among significant risk factors for DP in TRD were female sex, being > 29 years of age, unemployment and a diagnosis of comorbid personality disorder (ICD-10 codes F60.0-9).

CONCLUSION

TRD is associated with an elevated risk for DP compared to other patients with depression, with large potential costs for the affected patients and for society. Clinical and therapeutic implications for patients with TRD who are granted DP should be further investigated.

LIMITATION

No clinical data, e.g. type of depression or reason for treatment switch, was available for this study.

Changes in Post-traumatic Stress Disorder Service Connection Among Veterans Under Age 55: An 18-Year Ecological Cohort Study

INTRODUCTION

Mandatory, age-based re-evaluations for post-traumatic stress disorder (PTSD) service connection contribute substantially to the Veterans Benefits Administration's work load, accounting for almost 43% of the 168,013 assessments for PTSD disability done in Fiscal Year 2017 alone. The impact of these re-evaluations on Veterans' disability benefits has not been described.

MATERIALS AND METHODS

The study is an 18-year, ecological, ambispective cohort of 620 men and 970 women receiving Department of Veterans Affairs PTSD disability benefits. Veterans were representatively sampled within gender; all were eligible for PTSD disability re-evaluations at least once because of age. Outcomes included the percentage whose PTSD service connection was discontinued, reduced, re-instated, or restored. We also examined total disability ratings among those with discontinued or reduced PTSD service connection. Subgroup analyses examined potential predictors of discontinued PTSD service connection, including service era, race/ethnicity, trauma exposure type, and chart diagnoses of PTSD or serious mental illness. Our institution's Internal Review Board reviewed and approved the study.

RESULTS

Over the 18 years, 32 (5.2%) men and 180 (18.6%) women had their PTSD service connection discontinued; among them, the reinstatement rate was 50% for men and 34.3% for women. Six men (1%) and 23 (2.4%) women had their PTSD disability ratings reduced; ratings were restored for 50.0% of men and 57.1% of women. Overall, Veterans who lost their PTSD service connection tended to maintain or increase their total disability rating. Predictors of discontinued PTSD service connection for men were service after the Vietnam Conflict and not having a Veterans Health Administration chart diagnosis of PTSD; for women, predictors were African American or black race, Hispanic ethnicity, no combat or military sexual assault history, no chart diagnosis of PTSD, and persistent serious mental illness. However, compared to other women who lost their PTSD service connection, African American and Hispanic women, women with no combat or military sexual assault history, and women with persistent serious illness had higher mean total disability ratings. For both men and women who lost their PTSD service connection, those without a PTSD chart diagnosis had lower mean total disability ratings than did their counterparts.

CONCLUSIONS

Particularly for men, discontinuing or reducing PTSD service connection in this cohort was rare and often reversed. Regardless of gender, most Veterans with discontinued PTSD service connection did not experience reductions in their overall, total disability rating. Cost-benefit analyses could help determine if mandated, age-based re-evaluations of PTSD service connection are cost-effective.

Twelve Months Post-treatment Results From the Norwegian Version of Improving Access to Psychological Therapies

Objectives

Prompt Mental Health Care (PMHC) is the Norwegian version of the England’s Improving Access to Psychological Therapies (IAPT). Both programs have been associated with substantial symptom reductions from pre- to post-treatment. The present study extends these findings by investigating symptom levels at 12 months post-treatment, as well as treatment outcome in relation to low- vs. high-intensity treatment forms.

Design and Outcome Measures

A prospective cohort design was used. All participants (n = 1530) were asked to complete the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 questionnaire (GAD-7) at baseline, before each session during treatment, at final treatment, and at 12 months post-treatment. Cohen’s d was used as effect size measure. Sensitivity analyses were conducted to examine the impact of the high missing data rates at post-treatment (≈44%) and 12 months post-treatment (≈58%).

Results

A large symptom reduction was seen from baseline to 12 months post-treatment for both PHQ (d = −0.98) and GAD (d = −0.94). Improvements observed at post-treatment were largely maintained at 12 months post-treatment (PHQ (Δd = 0.10) and GAD (Δd = 0.09). Recovery rates decreased only slightly from 49.5% at post-treatment to 45.0% at follow-up. Both low- and high-intensity treatment forms were associated with substantial and lasting symptoms reductions (−1.26 ≤ d ≤ −0.73). Sensitivity analyses did not substantially alter the main results.

Conclusion

The findings suggest long-lasting effects of the PMHC program and encourage the use of low-intensity treatment forms in PMHC like settings.

Using Longitudinal Survey Data to Estimate Mental Health Related Transitions to a Disability Pension: Analysis of an Australian Household Panel Study

OBJECTIVE

This study examined the association between mental ill-health and subsequent receipt of a disability pension in Australia, and assessed how the strength of the association varied in relation to the duration between mental health measurement and reported disability pension receipt.

METHODS

Eight thousand four hundred seventy-four working-age adults not receiving a disability pension at baseline were followed for up to 11 years; 349 transitioned onto a disability pension. Discrete-time survival analysis considered baseline and time-varying (12-month lagged) measures of mental ill-health.

RESULTS

Proximal measures of mental ill-health were more strongly associated with subsequent pension receipt than baseline measures (odds ratio: 6.6 vs 3.9) and accounted for a significantly greater proportion of pension transitions (35% vs 21%).

CONCLUSION

Mental ill-health is an independent risk factor for disability pension receipt, and proximal circumstances better capture this association than mental health measured earlier.

Development of an e-learning prototype for assessing occupational stress-related disorders: a qualitative study

BACKGROUND

Occupational stress-related disorders are complex to diagnose and prevent, due to their multifactorial origin. We developed an e-learning programme aimed at supporting occupational physicians when diagnosing and preventing occupational stress-related disorders. In order to explore the extent to which a developed e-learning prototype was perceived as useful and feasible by occupational physicians, we executed a qualitative study.

METHODS

We conducted semi-structured, face-to-face interviews with fifteen occupational physicians, who were recruited using a combination of convenience and purposive sampling. Participants were shown a hard copy prototype of the e-learning programme, on which they were invited to comment in terms of perceived usefulness and feasibility. The interview data was transcribed verbatim and coded by two researchers using a content analysis approach.

RESULTS

Occupational physicians perceived e-learning as useful when it contributed to creating a full clinical picture and supported the diagnosis. Its structure had to support occupational physicians to work systematically. The programme had to be applicable to their daily practice and had to incorporate learning tools in order to increase the competences of occupational physicians. Feasibility was perceived to increase when the e-learning programme took less time to complete, when the quantity of written text was not too high, and when the user was guided and recertification points provided.

CONCLUSIONS

An e-learning programme can be an asset in continuing medical education for occupational physicians when assessing occupational stress-related disorders. Perceived usefulness depended on the clinical picture, structure, practicality and the increasing of competences. Feasibility depended on text, time, structure and reward.

The impact of depressive symptoms on exit from paid employment in Europe: a longitudinal study with 4 years follow-up

Background

Mental health problems are a risk factor for loss of paid employment. This study investigates (i) the relation between depressive symptoms and different involuntary pathways of labour force exit and (ii) explores gender and geographical differences in this relation.

Methods

The study population consisted of 5263 individuals in paid employment aged between 50 years and the country-specific retirement age from 11 European countries participating in the longitudinal Survey of Health, Ageing and Retirement in Europe (SHARE). Self-reported depressive symptoms at baseline were assessed using the EURO-D. Employment status was derived from interviews after 2 and 4 years. Cox proportional hazards regression analyses were used to investigate the association between depressive symptoms and labour force exit via disability benefit and unemployment. Population attributable fractions (PAFs) were calculated to estimate the contribution of depressive symptoms to these pathways of labour force exit.

Results

Both men and women with a EURO-D score ≥4 had a >2-fold increased risk of a disability benefit (HR: 2.46, 95%CI 1.68–3.60) after adjustment for demographics and work-related characteristics. Among men depressive symptoms elevated the risk of becoming unemployed at follow-up (HR 1.55; 95%CI: 0.94–2.57). The PAF was 0.18 for disability benefit and 0.04 for unemployment, and varied across European regions.

Conclusions

Individuals with depressive symptoms are at increased risk of losing paid employment, which in turn may aggravate their symptoms. Targeting depressive symptoms with public health and occupational policies should be considered to reduce the burden of mental diseases in Europe.

Depression and risk of disability pension: A systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

Depression is a common mental disorder that leads to undesirable consequences. The study of the role of depression in disability pension can provide valuable insights. This study was conducted with the goal of systematic review and meta-analysis of the relationship between depression and disability pension.

METHODS

PubMed, Scopus, PsycInfo, and Google Scholar databases were systematically searched until March 2018. Fifteen prospective cohort studies were selected and included in the meta-analysis. The random-effects method was used to combine the studies. Subgroup analysis was performed, and publication bias was also examined.

RESULTS

Depression was a risk factor for disability pension (pooled risk ratio =1.68 and 95% confidence interval = 1.50-1.88). In men, pooled risk ratio was 1.82 for the effect of depression on the risk of disability pension (95% confidence interval = 1.45-2.28). In women, pooled risk ratio was 1.62 (95% confidence interval = 1.31-2.02). The results showed that there is publication bias.

CONCLUSIONS

Depression is a factor for retirement due to disability. Therefore, the prevention and treatment of depression can reduce socioeconomic and psychological consequences imposed on society.

Resilience@Work Mindfulness Program: Results From a Cluster Randomized Controlled Trial With First Responders

Background

A growing body of research suggests that resilience training can play a pivotal role in creating mentally healthy workplaces, particularly with regard to protecting the long-term well-being of workers. Emerging research describes positive outcomes from various types of resilience training programs (RTPs) among different occupational groups. One specific group of workers that may benefit from this form of proactive resilience training is first responders. Given the nature of their work, first responders are frequently exposed to stressful circumstances and potentially traumatic events, which may impact their overall resilience and well-being over time.

Objective

This study aimed to examine whether a mindfulness-based RTP (the Resilience@Work [RAW] Mindfulness Program) delivered via the internet can effectively enhance resilience among a group of high-risk workers.

Methods

We conducted a cluster randomized controlled trial (RCT) comprising 24 Primary Fire and Rescue and Hazmat stations within New South Wales. Overall, 12 stations were assigned to the 6-session RAW Mindfulness Program and 12 stations were assigned to the control condition. A total of 143 active full-time firefighters enrolled in the study. Questionnaires were administered at baseline, immediately post training, and at 6-month follow-up. Measurements examined change in both adaptive and bounce-back resilience as well as several secondary outcomes examining resilience resources and acceptance and mindfulness skills.

Results

Mixed-model repeated measures analysis found that the overall test of group-by-time interaction was significant (P=.008), with the intervention group increasing in adaptive resilience over time. However, no significant differences were found between the intervention group and the control group in terms of change in bounce-back resilience (P=.09). At 6-month follow-up, the group receiving the RAW intervention had an average increase in their resilience score of 1.3, equating to a moderate-to-large effect size compared with the control group of 0.73 (95% CI 0.38-1.06). Per-protocol analysis found that compared with the control group, the greatest improvements in adaptive resilience were observed among those who completed most of the RAW program, that is, 5 to 6 sessions (P=.002).

Conclusions

The results of this RCT suggest that mindfulness-based resilience training delivered in an internet format can create improvements in adaptive resilience and related resources among high-risk workers, such as first responders. Despite a number of limitations, the results of this study suggest that the RAW Mindfulness Program is an effective, scalable, and practical means of delivering online resilience training in high-risk workplace settings. To the best of our knowledge, this is the first time a mindfulness-based RTP delivered entirely via the internet has been tested in the workplace.

Leaving Productivism behind: Towards a Holistic and Processual Philosophy of Ecological Management

This article examines parallels between the increasing mental burnout and environmental overshoot in the organisational context. The article argues that there is a particular philosophy of management that connects these two phenomena of overshoot and burnout, namely productivism. As there are boundaries in all ecological processes and systems, the productivist aim of having ever more output and growth is deemed absurd. It is proposed that productivity as a management philosophy not only leads to mental ill-health in organisations but also to overshoot in the environment. The article concludes that productivism, which denies the limits in utilisation of humans and other natural resources, fits poorly with circular economy and sustainability. Hence, ecological management should be complemented with a more holistic and processual view of organizations, as well as have an aim of peaceful coexistence between all earthbound objects. This signifies acknowledging and caring for human and non-human needs both now and in future by applying the idea of moderation to production of goods and services.

An outreach collaborative model for early identification and treatment of mental disorder in Danish workplaces

BACKGROUND

Depression and anxiety are prevalent mental disorders among the working population with potentially high personal and financial cost. The overall aim of this study was to test the applicability of an outreach collaborative model for early identification and treatment of clinical and sub-clinical mental disorders among Danish employees. This applicability was examined by I) investigating the fractions of identified and treated clinical and subclinical cases, II) describing the distribution and characteristics of cases identified and III) investigating the effect of allocated treatment.

METHODS

A longitudinal study design with four assessments (T0-T3) over 16 months was applied. Self-reporting questionnaires probing for psychopathology were distributed to all employees in six consecutively enrolled companies at the four time points. Employees meeting the screening criteria at T1 were assessed diagnostically. Subjects diagnosed with a clinical mental disorder were allocated to outpatient psychiatric treatment, and subjects with subclinical conditions were allocated to preventive cognitive behavioural therapy. Follow-up was conducted 6 and 12 months after initiation of treatment. We used chi-squared test and F-test to compare the different groups on baseline characteristics and mixed effects linear regression to analyse the treatment effects.

RESULTS

Forty (6.8%) of the 586 responders at T1 were diagnosed with a clinical mental disorder and referred to outpatient psychiatric treatment. Thirty-three (5.6%) were affected by a subclinical condition and referred to preventive treatment. Nearly two-thirds (63%) of the employees diagnosed with a clinical condition had never received treatment before. Symptom severity decreased significantly for both treated groups until follow-up. When compared to a composed control group, subclinical cases displayed a more rapid initial significant symptomatic decrease on the global symptom scale (coefs = - 0.914, 95% CI [- 1.754, - 0,075]) and anxiety sub-scale (coefs = - 1.043, 95% CI [- 2.021, - 0.066]). This did not apply to the clinical cases as no significant difference in change were identified.

CONCLUSIONS

The outreach collaborative model demonstrated an applicability to identify both clinical and subclinical cases, among these a high number of employees with an unmet need for treatment. We found evidence of a positive initial effect on symptomatology from the allocated preventive treatment among the subclinical cases, but not for clinical cases.

Early intervention with cognitive behavioral therapy reduces sick leave duration in people with adjustment, anxiety and depressive disorders

Background: Early intervention in workers diagnosed with mental disorders is associated with a lower incidence of relapse and shorter sick leave. However, no studies have been carried out on the effect of early intervention using an evidence-based therapy, Cognitive Behavioral Therapy (CBT), on people with sick leave.Aims: The objectives of the present study are to study whether the type of intervention (early or late) will affect the total duration of the sick leave, the partial duration of the sick leave, the duration of the psychotherapy and the time until return to work after the psychotherapy ends. The sample was composed of 167 participants who were on sick leave for adjustment disorders, anxiety disorders or depressive disorder.Results: The participants who had early intervention with CBT had a significantly shorter duration of total sick leave and partial sick leave, and a shorter time until returning to work after the psychotherapy ended than those who had late intervention. There were no statistically differences in the duration or efficacy of the psychotherapy.Conclusion: We can suggest that providing early access to CBT significantly reduces the length of sick leave in patients with mental disorders.

Mindfulness-Based Resilience Training in the Workplace: Pilot Study of the Internet-Based Resilience@Work (RAW) Mindfulness Program

Background

The impact of mental illness on society is far reaching and has been identified as the leading cause of sickness absence and work disability in most developed countries. By developing evidence-based solutions that are practical, affordable, and accessible, there is potential to deliver substantial economic benefits while improving the lives of individual workers. Academic and industry groups are now responding to this public health issue. A key focus is on developing practical solutions that enhance the mental health and psychological resilience of workers. A growing body of research suggests resilience training may play a pivotal role in the realm of public health and prevention, particularly with regards to protecting the long-term well-being of workers.

Objective

Our aim is to examine whether a mindfulness-based resilience-training program delivered via the internet is feasible and engaging to a group of high-risk workers. Additionally, we aim to measure the effect of the Resilience@Work Resilience@Work Mindfulness program on measures of resilience and related skills.

Methods

The current pilot study recruited 29 full-time firefighters. Participants were enrolled in the 6-session internet-based resilience-training program and were administered questionnaires prior to training and directly after the program ended. Measurements examined program feasibility, psychological resilience, experiential avoidance, and thought entanglement.

Results

Participants reported greater levels of resilience after Resilience@Work training compared to baseline, with a mean increase in their overall resilience score of 1.5 (95% CI -0.25 to 3.18, t₁₄=1.84, P=.09). Compared to baseline, participants also reported lower levels of psychological inflexibility and experiential avoidance following training, with a mean decrease of -1.8 (95% CI -3.78 to 0.20, t₁₃=-1.94, P=.07). With regards to cognitive fusion (thought entanglement), paired-samples t tests revealed a trend towards reduction in mean scores post training (P=.12).

Conclusions

This pilot study of the Resilience@Work program suggests that a mindfulness-based resilience program delivered via the Internet is feasible in a high-risk workplace setting. In addition, the firefighters using the program showed a trend toward increased resilience and psychological flexibility. Despite a number of limitations, the results of this pilot study provide some valuable insights into what form of resilience training may be viable in occupational settings particularly among those considered high risk, such as emergency workers. To the best of our knowledge, this is the first time a mindfulness-based resilience-training program delivered wholly via the internet has been tested in the workplace.

Work Participation Among Employees with Common Mental Disorders: A Meta-synthesis

Purpose The aim was to aggregate knowledge about the opportunities, challenges and need for support employees with common mental disorders experience in relation to work participation in order to develop recommendations for practice. Methods A meta-synthesis was conducted using a meta-aggregative approach to accurately and reliably present findings that could be used to meet our aim. Qualitative inductive content analysis was used to analyze and synthesize the findings. Results In all, 252 findings were extracted from 16 papers, and six categories were generated and aggregated into two synthesized findings. One synthesized finding indicates that a strong work identity and negative perceptions regarding mental disorders can impede work participation, creating an essential need for a supportive work environment. The other reveals that the diffuse nature of the symptoms of mental disorders causes instability in life and loss of control, but through the use of internal motivation and external support, employees may be able to regain control of their lives. However, external support is hampered by insufficient cooperation and coordination between vocational stakeholders. Conclusions Based on the synthesized findings, we recommended that the employer is involved in the rehabilitation process, and that rehabilitation professionals seek to strengthen the employee's ability to manage work-related stress. In addition, rehabilitation professionals should provide individualized and active support and ensure meaningful cooperation across the multidisciplinary disciplines involved in the rehabilitation process.

A New Online Mental Health Training Program for Workplace Managers: Pre-Post Pilot Study Assessing Feasibility, Usability, and Possible Effectiveness

BACKGROUND

Mental health has become the leading cause of sickness absence in high-income countries. Managers can play an important role in establishing mentally healthy workplaces and coordinating their organization's response to a mentally ill worker.

OBJECTIVE

This pilot study aims to evaluate the feasibility, usability, and likely effectiveness of a newly developed online training program for managers called HeadCoach. HeadCoach aims to build managers' confidence in supporting the mental health needs of staff and promote managerial behavior most likely to result in a more mentally healthy workplace.

METHODS

In total, 66 managers from two organizations were invited to participate in this pre-post pilot study of HeadCoach, which was made available to managers to complete at their own pace over a 4-week period. Data were collected at baseline and post intervention via an online research platform. The difference in mean scores for each outcome between these two time points was calculated using paired samples t tests.

RESULTS

Of all the invited managers, 59.1% (39/66) participated in the trial, with complete pre-post data available for 56.4% (22/39) of the participants. The majority of respondents reported positive engagement with the program. During the study period, managers' knowledge regarding their role in managing mental health issues (P=.01) and their confidence in communicating with employees regarding mental illness (P<.001) significantly increased. In addition, a significant increase was observed from the baseline in managers' self-reported actions to use strategies to prevent and decrease stress among their team members (P=.02).

CONCLUSIONS

Although caution is needed due to the absence of a control group, preliminary results of this study suggest that HeadCoach could be a feasible, acceptable, and efficient method of training managers in best workplace practices to help support the mental health needs of their staff.

Views and Experiences of Persons with Chronic Diseases about Strategies that Aim to Integrate and Re-Integrate Them into Work: A Systematic Review of Qualitative Studies

The effectiveness of strategies targeting professional integration and reintegration strongly depends on the experiences of participants. The aim of this systematic literature review is to synthesize European qualitative studies exploring views and experiences of persons with chronic conditions regarding strategies for integration and reintegration into work. The systematic search was conducted in Medline, PsycINFO, CDR-HTA, CDR-DARE and Cochrane Systematic Reviews. Overall, 24 studies published in English between January 2011 and April 2016 were included. Most studies were carried out in Nordic countries or in the UK, and most participants were persons with either mental or musculoskeletal disorders. Ten themes emerged: individual and holistic approach, clarity of strategy and processes, timing of rehabilitation processes, experience with professionals, at the workplace and with peer groups, changes in the understanding of health and work, active involvement in the process, competencies development and motivating aspects of work. Findings highlight, among others, the need to actively involve participants in the return to work process and to provide timely and clearly structured processes and interventions. This review provides stakeholders key information to develop, plan, implement and evaluate interventions to integrate and re-integrate persons with chronic conditions into work in Europe.

Trajectories of antidepressant medication use in individuals before and after being granted disability pension due to common mental disorders- a nationwide register-based study

BACKGROUND

Early retirement caused by disability pension (DP) due to common mental disorders (CMDs) is frequent in European countries. Inadequate treatment, e.g., suboptimal antidepressant (AD) medication before DP can be crucial in such DP. This explorative study aimed to disentangle trajectories of AD based on defined daily dose (DDD) before and after granted DP, and to characterize the trajectories by socio-demographics and medical factors.

METHODS

All 4642 individuals in Sweden aged 19-64 with incident DP due to CMD in 2009-2010 were included. Trajectories of annual DDDs of AD were analysed over a 6-year period by a group-based trajectory method. Associations between socio-demographic or medical factors and different trajectories were estimated by chi2-test and multinomial logistic regression.

RESULTS

Five trajectories of ADs were identified. Three groups, comprising 34%, 34%, and 21% of the cohort, had constant AD levels before and after DP with mean annual DDDs of 29, 234, and 580, respectively. Two groups, each including 6% of the cohort, had increasing levels of DDDs, levelling off at around 1150 and 785 DDDs after DP. Particularly age, outpatient care due to mental diagnoses and DP diagnoses were significantly associated with different trajectories (p < 0.05). All the groups had a larger proportion of older individuals (> 50%, 45-64 years), except for the 'increasing low' group, where younger individuals were in majority (> 60%, 18-44 years), who more frequently exited labour market due to 'anxiety disorders', with lower education and more specialised healthcare before DP than the other groups.

CONCLUSION

The heterogeneity among the five trajectory groups was partly explained by age, the severity of the mental disorder and the DP diagnoses. DDDs of ADs, though on different levels, varied marginally before and after granted DP in the majority. Moreover, AD levels were very low in one third of the individuals. Early identification and focus on the 'increasing low' group might be important in order to identify individuals at risk for further increase in annual DDDs of ADs even after granted DP, and might also contribute in prevention of DP. Further detailed research regarding different groups is warranted.

Effectiveness of eHealth interventions for reducing mental health conditions in employees: A systematic review and meta-analysis

Background

Many organisations promote eHealth applications as a feasible, low-cost method of addressing mental ill-health and stress amongst their employees. However, there are good reasons why the efficacy identified in clinical or other samples may not generalize to employees, and many Apps are being developed specifically for this group. The aim of this paper is to conduct the first comprehensive systematic review and meta-analysis evaluating the evidence for the effectiveness and examine the relative efficacy of different types of eHealth interventions for employees.

Methods

Systematic searches were conducted for relevant articles published from 1975 until November 17, 2016, of trials of eHealth mental health interventions (App or web-based) focused on the mental health of employees. The quality and bias of all identified studies was assessed. We extracted means and standard deviations from published reports, comparing the difference in effect sizes (Hedge’s g) in standardized mental health outcomes. We meta-analysed these using a random effects model, stratified by length of follow up, intervention type, and whether the intervention was universal (unselected) or targeted to selected groups e.g. “stressed”.

Results

23 controlled trials of eHealth interventions were identified which overall suggested a small positive effect at both post intervention (g = 0.24, 95% CI 0.13 to 0.35) and follow up (g = 0.23, 95% CI 0.03 to 0.42). There were differential short term effects seen between the intervention types whereby Mindfulness based interventions (g = 0.60, 95% CI 0.34 to 0.85, n = 6) showed larger effects than the Cognitive Behaviour Therapy (CBT) based (g = 0.15, 95% CI 0.02 to 0.29, n = 11) and Stress Management based (g = 0.17, 95%CI -0.01 to 0.34, n = 6) interventions. The Stress Management interventions however differed by whether delivered to universal or targeted groups with a moderately large effect size at both post-intervention (g = 0.64, 95% CI 0.54 to 0.85) and follow-up (g = 0.69, 95% CI 0.06 to 1.33) in targeted groups, but no effect in unselected groups.

Interpretation

There is reasonable evidence that eHealth interventions delivered to employees may reduce mental health and stress symptoms post intervention and still have a benefit, although reduced at follow-up. Despite the enthusiasm in the corporate world for such approaches, employers and other organisations should be aware not all such interventions are equal, many lack evidence, and achieving the best outcomes depends upon providing the right type of intervention to the correct population.

Workplace mental health training for managers and its effect on sick leave in employees: a cluster randomised controlled trial

BACKGROUND

Mental illness is one of the most rapidly increasing causes of long-term sickness absence, despite improved rates of detection and development of more effective interventions. However, mental health training for managers might help improve occupational outcomes for people with mental health problems. We aimed to investigate the effect of mental health training on managers' knowledge, attitudes, confidence, and behaviour towards employees with mental health problems, and its effect on employee sickness absence.

METHODS

We did a cluster randomised controlled trial of manager mental health training within a large Australian fire and rescue service, with a 6-month follow-up. Managers (clusters) at the level of duty commander or equivalent were randomly assigned (1:1) using an online random sequence generator to either a 4-h face-to-face RESPECT mental health training programme or a deferred training control group. Researchers, managers, and employees were not masked to the outcome of randomisation. Firefighters and station officers supervised by each manager were included in the study via their anonymised sickness absence records. The primary outcome measure was change in sickness absence among those supervised by each of the managers. We analysed rates of work-related sick leave and standard sick leave seperately, with rate being defined as sickness absence hours divided by the sum of hours of sickness absence and hours of attendance. This trial was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12613001156774).

FINDINGS

128 managers were recruited between Feb 18, 2014, and May 17, 2014. 46 (71%) of 65 managers allocated to the intervention group received the intervention, and 42 (67%) of 63 managers allocated to the control group were entered in the deferred training group. Managers and their employees were followed up and reassessed at 6 months after randomisation. 25 managers (1233 employees) in the intervention group and 19 managers (733 employees) in the control group provided data for the primary analysis. During the 6-month follow-up, the mean rate of work-related sick leave decreased by 0·28 percentage points (pp) from a pre-training mean of 1·56% (SE 0·23) in the intervention group and increased by 0·28 pp from 0·95% (0·20) in the control group (p=0·049), corresponding to a reduction of 6·45 h per employee per 6 months. The mean percentage of standard sick leave increased by 0·48 pp from 4·97% (0·22) in the intervention group and by 0·31 pp from 5·27% (0·21) in the control group (p=0·169).

INTERPRETATION

A 4-h manager mental health training programme could lead to a significant reduction in work-related sickness absence, with an associated return on investment of £9.98 for each pound spent on such training. Further research is needed to confirm these findings and test their applicability in other work settings.

NIPSA: a new scale for measuring non-illness predictors of sickness absence

OBJECTIVES

We describe the development and initial validation of a new scale for measuring non-illness factors that are important in predicting occupational outcomes, called the NIPSA (non-illness predictors of sickness absence) scale.

METHODS

Forty-two questions were developed which covered a broad range of potential non-illness-related risk factors for sickness absence. 682 participants in the South East London Community Health study answered these questions and a range of questions regarding both short-term and long-term sickness absence. Factor analysis was conducted prior to examining the links between each identified factor and sickness absence outcomes.

RESULTS

Exploratory factor analysis using the oblique rotation method suggested the questionnaire should contain 26 questions and extracted four factors with eigenvalues greater than 1: perception of psychosocial work environment (factor 1), perceived vulnerability (factor 2), rest-focused attitude towards recovery (factor 3) and attitudes towards work (factor 4). Three of these factors (factors 1, 2 and 3) showed significant associations with long-term sickness absence measures (p<0.05), meaning a final questionnaire that included 20 questions with three subscales.

CONCLUSIONS

The NIPSA is a new tool that will hopefully allow clinicians to quickly assess for the presence of non-illness factors that may be important in predicting occupational outcomes and tailor treatments and interventions to address the barriers identified. To the best of our knowledge, this is the first time that a scale focused on transdiagnostic, non-illness-related predictors of sickness absence has been developed.

Impact of childhood and adulthood psychological health on labour force participation and exit in later life

BACKGROUND

Adulthood psychological health predicts labour force activity but few studies have examined childhood psychological health. We hypothesized that childhood psychological ill-health would be associated with labour force exit at 55 years.

METHOD

Data were from the 55-year follow-up of the National Child Development Study (n = 9137). Labour force participation and exit (unemployment, retirement, permanent sickness, homemaking/other) were self-reported at 55 years. Internalizing and externalizing problems in childhood (7, 11 and 16 years) and malaise in adulthood (23, 33, 42, 50 years) were assessed. Education, social class, periods of unemployment, partnership separations, number of children, and homemaking activity were measured throughout adulthood.

RESULTS

Childhood internalizing and externalizing problems were associated with unemployment, permanent sickness and homemaking/other at 55 years, after adjustment for adulthood psychological health and education: one or two reports of internalizing was associated with increased risk for unemployment [relative risk (RR) 1.59, 95% confidence interval (CI) 1.12-2.25; RR 2.37, 95% CI 1.48-3.79] and permanent sickness (RR 1.32, 95% CI 1.00-1.74; RR, 1.48, 95% CI 1.00-2.17); three reports of externalizing was associated with increased risk for unemployment (RR 2.26, 95% CI 1.01-5.04), permanent sickness (RR 2.63, 95% CI 1.46-4.73) and homemaking/other (RR 1.95, 95% CI 1.00-3.78).

CONCLUSIONS

Psychological ill-health across the lifecourse, including during childhood, reduces the likelihood of working in older age. Support for those with mental health problems at different life stages and for those with limited connections to the labour market, including homemakers, is an essential dimension of attempts to extend working lives.

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.

External Validation and Update of a Prediction Rule for the Duration of Sickness Absence Due to Common Mental Disorders

Purpose The objective of the present study was to validate an existing prediction rule (including age, education, depressive/anxiety symptoms, and recovery expectations) for predictions of the duration of sickness absence due to common mental disorders (CMDs) and investigate the added value of work-related factors. Methods A prospective cohort study including 596 employees who reported sick with CMDs in the period from September 2013 to April 2014. Work-related factors were measured at baseline with the Questionnaire on the Experience and Evaluation of Work. During 1-year follow-up, sickness absence data were retrieved from an occupational health register. The outcome variables of the study were sickness absence (no = 0, yes = 1) at 3 and 6 months after reporting sick with CMDs. Discrimination between workers with and without sickness absence was investigated at 3 and 6 months with the area under the receiver operating characteristic curve (AUC). Results A total of 220 (37 %) employees agreed to participate and 211 (35 %) had complete data for analysis. Discrimination was poor with AUC = 0.69 and AUC = 0.55 at 3 and 6 months, respectively. When 'variety in work' was added as predictor variable, discrimination between employees with and without CMD sickness absence improved to AUC = 0.74 (at 3 months) and AUC = 0.62 (at 6 months). Conclusions The original prediction rule poorly predicted CMD sickness absence duration. After adding 'variety in work', the prediction rule discriminated between employees with and without CMD sickness absence 3 months after reporting sick. This new prediction rule remains to be validated in other populations.

Health Problems during Compulsory Military Service Predict Disability Retirement: A Register-Based Study on Secular Trends during 40 Years of Follow-Up

Disability retirement causes a significant burden on the society and affects the well-being of individuals. Early health problems as determinants of disability retirement have received little attention. The objective was to study, whether interrupting compulsory military service is an early indicator of disability retirement among Finnish men and whether seeking medical advice during military service increases the risk of all-cause disability retirement and disability retirement due to mental disorders and musculoskeletal diseases. We also looked at secular trends in these associations. We examined a nationally representative sample of 2069 men, who had entered military service during 1967–1996. We linked military service health records with cause-specific register data on disability retirement from 1968 to 2008. Secular trends were explored in three service time strata. We used the Cox regression model to estimate proportional hazard ratios and their 95% confidence intervals. During the follow-up time altogether 140 (6.8%) men retired due to disability, mental disorders being the most common cause. The men who interrupted service had a remarkably higher cumulative incidence of disability retirement (18.9%). The associations between seeking medical advice during military service and all-cause disability retirement were similar across the three service time cohorts (overall hazard ratio 1.40 per one standard deviation of the number of visits; 95% confidence interval 1.26–1.56). Visits due to mental problems predicted disability retirement due to mental disorders in the men who served between 1987 and 1996 and a tendency for a similar cause-specific association was seen for musculoskeletal diseases in the men who served in 1967–1976. In conclusion, health problems—in particular mental problems—during late adolescence are strong determinants of disability retirement. Call-up examinations and military service provide access to the entire age cohort of men, where persons at risk for work disability can be identified and early preventive measures initiated.

The mental health benefits of employment: Results of a systematic meta-review

OBJECTIVE

The literature on mental health in the workplace largely focuses on the negative impacts of work and how work may contribute to the development of mental disorders. The potential mental health benefits of employment have received less attention.

METHOD

A systematic search of reviews or meta-analyses that consider the benefits of work in regards to mental health was undertaken using academic databases. All relevant reviews were subjected to a quality appraisal.

RESULTS

Eleven reviews were identified as meeting the inclusion criteria, with four deemed to be of at least moderate quality. The available evidence supports the proposition that work can be beneficial for an employee's well-being, particularly if good-quality supervision is present and there are favourable workplace conditions. The benefits of work are most apparent when compared with the well-documented detrimental mental health effects of unemployment.

CONCLUSIONS

The potential positive effects of good work and the role work can play in facilitating recovery from an illness and enhancing mental well-being need to be highlighted and promoted more widely. Future research should aim to further investigate what constitutes a 'good' workplace or a 'good' job in terms of mental health outcomes.

Long-term physical workload in middle age and disability pension in men and women: a follow-up study of Swedish cohorts

Purpose

The study investigates the association between level of long-term physical workload in middle age and disability pension (DP) before 61 years of age with adjustments made for early life factors, level of education, and psychosocial working conditions. Associations with DP overall, DP due to musculoskeletal disorders and DP due to psychiatric disorders were examined.

Methods

The study is based on cohorts of 21,809 Swedish men and women born in 1948 and 1953, with data on physical workload estimated with a job exposure matrix based on occupational titles in 1985 and 1990 and follow-up data on diagnosis-specific DP in the years 1991–2009. Data on paternal education and intelligence were collected in primary school. Data on level of education were taken from administrative records. Data on psychosocial working conditions were estimated with a job exposure matrix based on occupational titles in 1990.

Results

Long-term exposure to high physical workload measured 5 years apart at around age 40 was strongly associated with DP due to musculoskeletal disorders up to the age of 61 among both men (HR 5.44, 95 % CI 3.35–8.84) and women (HR 3.82, CI 95 % 2.88–5.08). For women, the association between high physical load and overall DP was also significantly increased (HR 2.33, CI 95 % 1.92–2.82). The increased risks remained but were clearly attenuated after adjustments for fathers’ education, IQ in childhood, achieved education and level of control at work.

Conclusions

Exposure to high physical workload is associated with long-term risk of DP due to musculoskeletal disorders, even though adjustments for early life factors, level of education and psychosocial working conditions clearly attenuated the risks.

Coping With Strain (CWS) course - its effects on depressive symptoms: A four-year longitudinal randomized controlled trial

The Coping With Strain (CWS) course is a modification of the Coping With Depression (CWD) course. CWD is by far the most studied psycho-educational intervention to reduce and prevent depression, but CWD has never been tested in a randomized controlled trial in the workplace. This study seeks to examine the extent to which CWS, on a short-term and a long-term basis, reduces depressive symptoms in employees. After advertising at workplaces, 119 employees were randomized into Intervention Group I (IG1), which immediately participated in CWS, or Intervention Group II (IG2), which functioned as a control group for six months until its participation in CWS. The follow up period lasted for four years in both IG1 and IG2. Linear mixed models were fitted to the data. Depressive symptoms were significantly reduced during the course. The reduction of depressive symptoms was maintained over a period of four years in both IG1 and IG2, although there is a slight increase towards the end of the follow-up period. CWS is effective in reducing depressive symptoms among employees. The effects are long lasting and may be maintained over a period of four years.

Workplace interventions for common mental disorders: a systematic meta-review

Depression and anxiety disorders are the leading cause of sickness absence and long-term work incapacity in most developed countries. The present study aimed to carry out a systematic meta-review examining the effectiveness of workplace mental health interventions, defined as any intervention that a workplace may either initiate or facilitate that aims to prevent, treat or rehabilitate a worker with a diagnosis of depression, anxiety or both. Relevant reviews were identified via a detailed systematic search of academic and grey literature databases. All articles were subjected to a rigorous quality appraisal using the AMSTAR assessment. Of the 5179 articles identified, 140 studies met the inclusion criteria, of which 20 were deemed to be of moderate or high quality. Together, these reviews analysed 481 primary research studies. Moderate evidence was identified for two primary prevention interventions; enhancing employee control and promoting physical activity. Stronger evidence was found for CBT-based stress management although less evidence was found for other secondary prevention interventions, such as counselling. Strong evidence was also found against the routine use of debriefing following trauma. Tertiary interventions with a specific focus on work, such as exposure therapy and CBT-based and problem-focused return-to-work programmes, had a strong evidence base for improving symptomology and a moderate evidence base for improving occupational outcomes. Overall, these findings demonstrate there are empirically supported interventions that workplaces can utilize to aid in the prevention of common mental illness as well as facilitating the recovery of employees diagnosed with depression and/or anxiety.

Mental health symptoms identify workers at risk of long-term sickness absence due to mental disorders: prospective cohort study with 2-year follow-up

Background

Mental health problems are a leading cause of long-term sickness absence (LTSA). Workers at risk of mental LTSA should preferably be identified before they report sick. The objective of this study was to examine mental health symptoms as predictors of future mental LTSA in non-sicklisted workers.

Methods

Prospective cohort study of 4877 non-sicklisted postal workers. Mental health symptoms were measured at baseline in November 2010 with the Four-Dimensional Symptom Questionnaire (distress and depressed mood) and Maslach’s Burnout Inventory (fatigue). Mental health symptom scores were analyzed against incident mental LTSA retrieved from an occupational health register in 2011 and 2012. The area under the receiver operating characteristic curve (AUC) represented the ability of mental health symptom scores to discriminate between workers with and without mental LTSA during 2-year follow-up.

Results

Complete cases analysis included 2782 (57 %) postal workers of whom 73 had mental LTSA during 2-year follow-up. Distress fairly (AUC = 0.75; 95 % CI 0.67–0.82) and both depressed mood (AUC = 0.64; 95 % CI 0.57–0.72) and fatigue (AUC = 0.61; 95 % CI 0.53–0.69) poorly discriminated between workers with and without mental LTSA during 2-year follow-up. The discriminative ability of distress did not improve by adding depressed mood and fatigue.

Conclusions

Measurement of distress sufficed to identify non-sicklisted postal workers at risk of future mental LTSA. The Four-Dimensional Symptom Questionnaire distress scale is a promising tool to screen working populations for of mental LTSA, which enables secondary preventive strategies.

Genetic and Environmental Influences on Disability Pension Due To Mental Diagnoses: Limited Importance of Major Depression, Generalized Anxiety, and Chronic Fatigue

BACKGROUND

Previous research indicates that liability to disability pension (DP) due to mental diagnoses is moderately influenced by genetic factors. This study investigates whether genetic contributions to the liability to DP due to mood and neurotic diagnoses overlap with the genetic influences on major depression (MD), generalized anxiety disorder (GAD), or chronic fatigue (CF).

METHOD

A prospective cohort study including 9,985 female twins born in Sweden 1933-1958. The presence of MD, GAD, and CF was assessed by computer-assisted telephone interviews conducted in 1998-2002. Data on DP due to mood and neurotic diagnoses were obtained from nationwide registers for the years 1998-2010. Common genetic and environmental influences on the phenotypes were estimated by applying structural equation modeling.

RESULTS

The prevalence of MD/GAD was 30%, CF 8%, and DP due to mood and neurotic diagnoses 3% in 2010. Genetic effects on MD/GAD explained 31% of the total genetic variation in DP, whereas genetic contributions in common with CF were small and not significant. The majority of the total non-shared environmental variance in DP (85%) was explained by the factors that were unique to DP.

CONCLUSIONS

Large proportions of genetic and non-shared environmental influences in DP due to mood and neurotic diagnoses were not explained by the contributions from MD/GAD or CF. The results suggest that the process leading to DP is complex and influenced by factors other than those related to the disorder underlying DP.

Disability pension and symptoms of anxiety and depression: a prospective comparison of farmers and other occupational groups. The HUNT Study, Norway

OBJECTIVES

Agriculture has undergone major changes, and farmers have been found to have a high prevalence of depression symptoms. We investigated the risk of work disability in Norwegian farmers compared with other occupational groups, as well as the associations between symptoms of anxiety and depression and future disability pension.

METHODS

We linked working participants of the HUNT2 Survey (1995-97) aged 20-61.9 years, of whom 3495 were farmers and 25,521 had other occupations, to national registry data on disability pension, with follow-up until 31 December 2010. We used Cox proportional hazards regression to estimate hazard ratios (HRs) of disability pension, and to investigate the associations between symptoms of anxiety and depression caseness at baseline (score on the anxiety or depression subscales of the Hospital Anxiety and Depression Scale (HADS) ≥8) and disability pension.

RESULTS

Farmers had a twofold increased risk of disability pension (age-adjusted and sex-adjusted HR 2.07, 95% CI 1.80 to 2.38) compared with higher grade professionals. Farmers with symptoms of depression caseness had a 53% increased risk of disability pension (HR 1.53, 95% CI 1.25 to 1.87) compared with farmers below the cut-off point of depression caseness symptoms, whereas farmers with symptoms of anxiety caseness had a 51% increased risk (HR 1.51, 95% CI 1.23 to 1.86).

CONCLUSIONS

Farmers have an increased risk of disability pension compared with higher grade professionals, but the risk is lower than in most other manual occupational groups. Farmers who report high levels of depression or anxiety symptoms are at substantially increased risk of future work disability, and the risk increase appears to be fairly similar across most occupational groups.
