To analyze the relationships between insight, medication adherence, addiction, coping and social support-components of Illness Management and Recovery (IMR)-as determinants of clinical, functional and personal recovery in patients with schizophrenia and other severe mental illnesses. Our rationale lay in the interrelations between these concepts suggested in a conceptual framework of IMR.
The cross-sectional design used baseline data of outpatient participants in a randomized clinical trial on IMR (N = 187). We used structural equation modeling (SEM) to describe pathways between degrees of insight, medication adherence, addiction, coping and social support, and degree of clinical, functional and personal recovery. We also explored whether clinical recovery mediated functional and personal recovery.
Our final model showed that coping was associated with clinical, functional and personal recovery. Direct associations between coping and functional and personal recovery were stronger than indirect associations via clinical recovery. Although SEM also showed a significant but weak direct pathway between social support and functional recovery, there were no significant pathways either between social support and clinical or personal recovery, or between insight, medication adherence, addiction and any type of recovery.
Coping may be a determinant of all three types of recovery, and social support a determinant of functional recovery. Clinical recovery appears not to be a prerequisite for functional or personal recovery. While our results also suggest the relevance of improving coping skills and of enhancing social support, they only partially support the conceptual framework of IMR.

Background
Social functioning, symptoms, cognition and well-being are all considered important recovery domains for patients with schizophrenia spectrum disorders (SSD). In the current study, we investigated to what extent longitudinal changes in one recovery domain moderated changes in another recovery domain, and which personal, clinical or social patient characteristics influence changes in recovery domains for patients with SSD.
Methods
We investigated data from GROUP, a prospective, longitudinal six-year study of patients with SSD. We analyzed longitudinal changes in 15 outcomes (i.e., subdomains of symptoms, social functioning, cognition, quality of life or well-being), through a linear mixed-effects model analysis. Changes in other outcomes, patients’ duration of illness (DOI), and personal, clinical, or social patient characteristics at baseline were treated as covariates in the analyses.
Results
We observed long-term improvement in all outcomes, except for depressive symptoms and subjective well-being. Larger improvements in positive symptoms, social functioning and executive functioning were indicated for patients with a short DOI. We found multiple, moderating effects, mainly for patients with a short DOI, between changes in cognition, social functioning, symptoms and quality of life. Limited moderating effects were indicated between these recovery domains and well-being. Baseline levels of outcomes, schizophrenia diagnosis, education level, ethnicity, living situation, employment status and marital status were all moderators for changes in most outcomes.
Conclusions
Symptoms, social functioning, cognition and quality of life often concurrently improved over the course of SSD. These longitudinal changes were mostly driven by social patient characteristics, such as education level, ethnicity, living situation, employment status and marital status.

BackgroundPatients with bipolar disorder experience impairments in their occupational functioning, despite remission of symptoms. Previous research has shown that neurocognitive deficits, especially deficits in executive functions, may persist during euthymia and are associated with diminished occupational functioning.ObjectivesThe aim of this scoping review was to identify published studies that report on the relationships between executive functions and occupational functioning in BD to review current knowledge and identify knowledge gaps. In addition to traditional neuropsychological approaches, we aimed to describe executive functioning from a self-regulation perspective, including emotion regulation.MethodsWe applied the methodological framework as described by Arksey and O’Malley (Int J Soc Res Methodol Theory Pract 8:19–32, 2005) and Levac et al. (Implement Sci 5:1–9, 2010). We searched PubMed and psycINFO for literature up to November 2021, after which we screened papers based on inclusion criteria. Two reviewers independently performed the screening process, data charting process, and synthesis of results.ResultsThe search yielded 1202 references after deduplication, of which 222 remained after initial screening. The screening and inclusion process yielded 82 eligible papers in which relationships between executive functions and occupational functioning are examined.ConclusionNeurocognitive deficits, including in executive functions and self-regulation, are associated with and predictive of diminished occupational functioning. Definitions and measurements for neurocognitive functions and occupational functioning differ greatly between studies, which complicates comparisons. Studies on functional remediation show promising results for improving occupational functioning in patients with BD. In research and clinical practice more attention is needed towards the quality of work functioning and the various contexts in which patients with BD experience deficits.

Psychiatric rehabilitation (PR) can improve functioning in people with severe mental illness (SMI), but outcomes are still suboptimal. Cognitive impairments have severe implications for functioning and might reduce the effects of PR. It has been demonstrated that performance in cognitive tests can be improved by cognitive remediation (CR). However, there is no consistent evidence that CR as a stand-alone intervention leads to improvements in real-life functioning. The present study investigated whether a combination of PR and CR enhances the effect of a stand-alone PR or CR intervention on separate domains of functioning.
A meta-analysis of randomized controlled trials of PR combined with CR in people with SMI was conducted, reporting on functioning outcomes. A multivariate meta-regression analysis was carried out to evaluate moderator effects.
The meta-analysis included 23 studies with 1819 patients. Enhancing PR with CR had significant beneficial effects on vocational outcomes (e.g. employment rate: SMD = 0.41), and social skills (SMD = 0.24). No significant effects were found on relationships and outcomes of community functioning. Effects on vocational outcomes were moderated by years of education, intensity of the intervention, type of CR approach and integration of treatment goals for PR and CR. Type of PR was no significant moderator.
Augmenting PR by adding cognitive training can improve vocational and social functioning in patients with SMI more than a stand-alone PR intervention. First indications exist that a synergetic mechanism also works the other way around, with beneficial effects of the combined intervention compared with a stand-alone CR intervention.

Long-term Changes in Personal Recovery and Quality of Life Among Patients With Schizophrenia Spectrum Disorders and Different Durations of Illness: A Meta-analysis
2024
Abstract
Background and Hypothesis
In schizophrenia spectrum disorders (SSD) personal recovery and subjective quality of life (S-QOL) are crucial and show conceptual overlap. There is limited knowledge about how these outcomes change over time. Therefore, we investigated changes in personal recovery or S-QOL for patients with SSD. We specifically focused on the influence of the patients’ durations of illness (DOI) on changes in personal recovery and S-QOL.
Study Design
We included 46 studies investigating longitudinal changes in quantitative assessments of personal recovery or S-QOL for patients with SSD. Outcomes were categorized in overall personal recovery, overall S-QOL connectedness, hope and optimism, identity, meaning in life, and empowerment. We evaluated effect sizes of change between baseline and follow-up assessments. We also evaluated potential moderating effects, including DOI on these changes in outcomes.
Study Results
We found small improvements of overall personal recovery and S-QOL, but marginal or no improvement over time in the other more specific outcome domains. Patients without a schizophrenia diagnosis, a younger age, and more recent publications positively influenced these changes. We found no significant influence of DOI on the changes in any outcome domain.
Conclusions
Improvement in personal recovery or S-QOL of people with SSD is modest at best. However, these studies did not fully capture the personal narratives or nonlinear process of recovery of an individual. Future research should focus on how to shift from a clinical to more person-oriented approach in clinical practice to support patients in improving their personal process of recovery.

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.
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.
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.
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.

Fidelity and IPS: does quality of implementation predict vocational outcomes over time for organizations treating persons with severe mental illness in the Netherlands?
2020
PurposeIndividual placement and support (IPS) is an evidence-based supported employment intervention. Quality of IPS implementation is assessed using a validated fidelity scale. Previous studies found a positive association between fidelity and employment outcomes at a single time-point. This study examines the longitudinal associations between IPS fidelity scores and employment outcomes.MethodsWe examined fidelity and employment outcome data for 27 IPS programs in the Netherlands providing IPS. These programs received at least one fidelity assessment and reported quarterly employment outcomes for at least one year to a central registry between 2014 and 2019. We first examined changes over time for fidelity and employment outcome. Then we analyzed the longitudinal associations between the quarterly employment outcomes and the IPS fidelity assessments on multiple time-points using a mixed-model analysis for the 17 programs with at least two fidelity assessments.ResultsBoth IPS fidelity and employment outcomes improved over time, with the largest improvement in employment outcomes achieved after 18 months of implementation. We found a significant positive longitudinal association between IPS-fidelity and employment.ConclusionsImprovement of fidelity is associated with improvement of employment outcomes over time. Future research should be focused on the improvement of specific elements of IPS implementation and their influence on employment outcomes.

ObjectivesStigma may negatively affect line managers’ intention to hire people with mental health problems (MHP). This study aims to evaluate line managers’ knowledge and attitudes concerning job applicants with MHP, and to assess which factors are associated with the intention (not) to hire an applicant with MHP.MethodsA sample of Dutch line managers (N=670) filled out a questionnaire on their knowledge, attitudes and experiences concerning applicants/employees with MHP. Descriptive analyses and multiple regression analyses were used.ResultsThe majority (64%) was reluctant to hire a job applicant with MHP, despite the fact that only 7% had negative and 52% had positive personal experiences with such employees. Thirty per cent were reluctant to hire an applicant if they knew the applicant had past MHP. Associated with higher reluctance to hire an applicant with MHP were the concerns that it will lead to long-term sickness absence (β (95% CI)=0.39 (0.23 to 0.55)), that the employee cannot handle the work (β (95% CI)=0.16 (0.00 to 0.33)) that one cannot count on the employee (β (95% CI)=0.41 (0.23 to 0.58)) and higher manager education level (β (95% CI)=0.25 (0.05 to 0.44)). Conversely, associated with positive hiring intentions was being in favour of diversity and/or inclusive enterprise (β(95% CI)=−0.64 (−0.87 to −0.41)).ConclusionsAs the majority of managers were reluctant to hire applicants with MHP, and even 30% were reluctant to hire applicants who had past MHP, these findings have major implications for social inclusion in the Netherlands, where about 75% of employees would disclose MHP at work.

This study analyzed the association between changes over time in illness self-management skills and personal recovery in patients with schizophrenia and other severe mental illnesses and determined the degree to which this association was mediated by changes in clinical and functional recovery. The rationale for the hypothesized directions of association and mediation originated from a recent randomized controlled trial (RCT) on Illness Management and Recovery (IMR), the relations between these concepts suggested in a conceptual framework of IMR, and from the results of three meta-analyses. Moreover, earlier studies indicated the relevance of examining personal recovery as an outcome for people with severe mental illnesses. Outpatient participants’ data were used in this RCT (N = 165). Difference scores were constructed for all concepts by subtracting scores measured at baseline (T1) from scores at follow-up measurement (T3). We used mediation analysis to describe pathways between changes in illness management (assessed using the Illness Management and Recovery scale client version) and changes in personal recovery (assessed using the Mental-Health Recovery Measure), mediated by changes in clinical (assessed using the Brief Symptom Inventory) and functional recovery (assessed using the Social Functioning Scale). We applied the baseline data of all concepts as covariates. As inferential tests to determine the significance of the indirect paths, confidence intervals were constructed using bootstrap techniques. The results showed that the improvement in overall illness management was directly associated with improvements in personal recovery (B = .30), and indirectly through improvements in clinical recovery (indirect effect = .13) and functional recovery (indirect effect = .08). The main conclusion is that self-reported illness management appears to be more strongly and directly associated with personal recovery than indirectly via clinical and functional recovery. This analysis supports the relevance of self-management interventions such as IMR for the personal recovery of people with severe mental illnesses.

Research on the recovery domains beside clinical recovery of people with severe mental illness in need of supported accommodations is limited. The aim of this study was (1) to investigate which recovery interventions exist for this group of people and (2) to explore the scientific evidence. We conducted a scoping review, including studies with different designs, evaluating the effectiveness the recovery interventions available. The search resulted in 53 eligible articles of which 22 focused on societal recovery, six on personal recovery, five on functional recovery, 13 on lifestyle-interventions, and seven on creative and spiritual interventions. About a quarter of these interventions showed added value and half of them initial promising results. The research in this area is still limited, but a number of recovery promoting interventions on other areas than clinical recovery have been developed and evaluated. Further innovation and research to strengthen and repeat the evidence are needed.
