Predictors of work and education among people with severe mental illness who participated in the Danish individual placement and support study: findings from a randomized clinical trial

Predictors of Return to Work for People with Anxiety or Depression Participating in a Randomized Trial Investigating the Effect of a Supported Employment Intervention

Purpose Common mental disorders have a severe impact on society and individuals; rates of unemployment and disability pensions are high. Knowing which factors facilitate or hinder people's return to work is important when designing effective vocational rehabilitation interventions. Methods We conducted secondary analyses on data from 289 participants with depression or anxiety included in the Individual Placement and Support modified for people with mood and anxiety disorders (IPS-MA) trial. Associations of baseline characteristics and employment or education after 24 months were tested in univariate logistic regression analyses, variables with a p-value below 0.1 were included in multivariate analyses. Results In the univariate analyses, self-reported level of functioning (p = 0.032), higher age (p = 0.070), and higher level of readiness to change (p = 0.001) were associated with the outcome and included in the multivariate analysis. Only age (p = 0.030) and readiness to change (p = 0.003) remained significantly associated with return to work or education after 24 months in the multivariate analysis. Conclusion Higher age and lower readiness to change were associated with a lower chance of having returned to work or education. Factors modifying the effect of higher age should be identified, just as vocational rehabilitation should focus on improving factors related to people's readiness to change.

Development of a model for shared care between general practice and mental healthcare: a protocol for a co-production study

INTRODUCTION

Mental health illness represents one of the greatest health burdens in the world. It is well documented that treatment of these illnesses could be optimised through strengthened collaboration between general practice and specialised mental healthcare services (shared care). Furthermore, involvement of users in the design of new interventions to strengthen end-user value and sustainability is key. Therefore, the aim of this study is to develop a shared care intervention in co-production with users.

METHODS AND ANALYSIS

The study will take place at psychiatric outpatient clinics in Denmark.The project is described in four sequential steps, each informing and leading into the next: a systematic review (step 1) will be followed by an exploratory study investigating how stakeholders (general practitioners, mental healthcare staff and patients) perceive existing treatment and collaboration between general practice and mental health services. Steps 1 and 2 will inform and qualify the intervention that will be developed in step 3 as a co-creation study. Step 4 will assess the intervention in a feasibility study. Step 4 will be designed as a non-randomised intervention study with a control group with preassessments and postassessments. In total, 240 patients will be recruited. Questionnaires will be administered to the participants at their first visit to an outpatient clinic and again after 3 months. The primary outcome will be patients' self-reported mental health status (Short Form Health Survey, SF-36) and recovery (revised Recovery Assessment Scale, RAS-R). Recruitment will take place from June 2023 to May 2024.

ETHICS AND DISSEMINATION

The project is approved by the ethics committee (REG-016-2022). Informed consent based on written and verbal information about the aims, purpose and use of the study and the data collection will be obtained from all participants. The study findings will be published in peer-reviewed journals and presented at national and international conferences. The study is registered at ClinicalTrials.gov.

Who benefits from individual placement and support? A meta-analysis

AIMS

Individual placement and support (IPS) is an evidence-based service model to support people with mental disorders in obtaining and sustaining competitive employment. IPS is increasingly offered to a broad variety of service users. In this meta-analysis we analysed the relative effectiveness of IPS for different subgroups of service users both based on the diagnosis and defined by a range of clinical, functional and personal characteristics.

METHODS

We included randomised controlled trials that evaluated IPS for service users diagnosed with any mental disorder. We examined effect sizes for the between-group differences at follow-up for three outcome measures (employment rate, job duration and wages), controlling for methodological confounders (type of control group, follow-up duration and geographic region). Using sensitivity analyses of subgroup differences, we analysed moderating effects of the following diagnostic, clinical, functional and personal characteristics: severe mental illness (SMI), common mental disorders (CMD), schizophrenia spectrum disorders, mood disorders, duration of illness, the severity of symptoms, level of functioning, age, comorbid alcohol and substance use, education level and employment history.

RESULTS

IPS is effective in improving employment outcomes compared to the control group in all subgroups, regardless of any methodological confounder. However, IPS was relatively more effective for service users with SMIs, schizophrenia spectrum disorders and a low symptom severity. Although IPS was still effective for people with CMD and with major depressive disorder, it was relatively less effective for these subgroups. IPS was equally effective after both a short and a long follow-up period. However, we found small, but clinically not meaningful, differences in effectiveness of IPS between active and passive control groups. Finally, IPS was relatively less effective in European studies compared to non-European studies, which could be explained by a potential benefits trap in high welfare countries.

CONCLUSIONS

IPS is effective for all different subgroups, regardless of diagnostic, clinical, functional and personal characteristics. However, there might be a risk of false-positive subgroup outcomes and results should be handled with caution. Future research should focus on whether, and if so, how the IPS model should be adapted to better meet the vocational needs of people with CMD and higher symptom severity.

Neuropsychological predictors of vocational rehabilitation outcomes in individuals with major depression: A scoping review

BACKGROUND

Major depression is one of the leading causes of disability and limited capacity to work. Neuropsychological impairment is a common symptom in acute and remitted major depression and is associated with poor psychosocial functioning. This scoping review aimed to identify research on the role of neuropsychological functioning in outcomes of vocational rehabilitation programs in individuals with depression.

METHODS

We report on the conduct of this pre-registered (https://osf.io/5yrnf) scoping review in accordance with PRISMA-ScR guidelines. PubMed and PsychInfo were systematically searched for English or German research articles published between 1990 and September 2021 that studied objective neuropsychological tests as predictors of vocational rehabilitation interventions and included participants with depression.

RESULTS

The systematic literature search yielded no studies that specifically targeted subjects with major depression. However, eight articles published since 2016 were included in the review, analyzing data from five trials that evaluated the effectiveness of supported employment in North America and Europe in severe mental illnesses. An estimated 31% of the total number of participants included (n = 3,533) had major depression. Using a variety of cognitive tests and covariates, seven articles found that neuropsychological functioning - especially global cognition scores, verbal and visual learning and memory - significantly predicted vocational outcomes of rehabilitation programs.

CONCLUSION

Despite a lack of studies specifically targeting major depressive disorder, the identified literature suggests that higher baseline neuropsychological functioning predicts better vocational outcomes of supported employment programs in individuals with depression. In clinical practice, additional neuropsychological modules during return-to-work interventions might be helpful for vocational outcomes of such programs.
