Prevalence, Employment Rate, and Cost of Schizophrenia in a High-Income Welfare Society: A Population-Based Study Using Comprehensive Health and Welfare Registers

Schizophrenia is associated with recurrent hospitalizations, need for long-term community support, poor social functioning, and low employment rates. Despite the wide- ranging financial and social burdens associated with the illness, there is great uncertainty regarding prevalence, employment rates, and the societal costs of schizophrenia. The current study investigates 12-month prevalence of patients treated for schizophrenia, employment rates, and cost of schizophrenia using a population-based top-down approach. Data were obtained from comprehensive and mandatory health and welfare registers in Norway. We identified a 12-month prevalence of 0.17% for the entire population. The employment rate among working-age individuals was 10.24%. The societal costs for the 12-month period were USD 890 million. The average cost per individual with schizophrenia was USD 106 thousand. Inpatient care and lost productivity due to high unemployment represented 33% and 29%, respectively, of the total costs. The use of mandatory health and welfare registers enabled a unique and informative analysis on true population-based datasets.

The MATRICS Consensus Cognitive Battery (MCCB): Performance and functional correlates

Neurocognitive impairment is a core feature in psychotic disorders and the MATRICS Consensus Cognitive Battery (MCCB) is now widely used to assess neurocognition in this group. The MATRICS has been translated into several languages, including Norwegian; although this version has yet to be investigated in an adult clinical population. Further, the relationship between the MATRICS and different measures of functioning needs examination. The purpose of this study was to describe neurocognition assessed with the Norwegian version of the MATRICS battery in a sample of patients with psychotic disorders compared to age and gender matched healthy controls and to examine the association with educational-, occupational- and social-functioning in the patient group. One hundred and thirty one patients and 137 healthy controls completed the battery. The Norwegian version of the MATRICS was sensitive to the magnitude of neurocognitive impairments in patients with psychotic disorders, with patients displaying significant impairments on all domains relative to healthy controls. Neurocognition was also related to both self-rated and objective functional measures such as social functioning, educational- and employment-history.

Employment outcome and predictors of competitive employment at 2-year follow-up of a vocational rehabilitation programme for individuals with schizophrenia in a high-income welfare society

Abstract Background: Employment is an important part of recovery for individuals with schizophrenia. The employment rate for this group is as low as 10% in Norway, and major system related barriers to employment are evident. Aims: This study reports the competitive employment outcome at 2-year follow-up of a vocational rehabilitation study augmented with cognitive remediation (CR) or elements from cognitive behaviour therapy (CBT) for individuals with schizophrenia spectrum disorders. It also investigates if global functioning, self-esteem, and depression at baseline predicts employment outcome, and if change in these variables during the intervention period is associated with employment outcome. Method: One hundred and forty-eight participants with schizophrenia spectrum disorders in six Norwegian counties received 10 months vocational rehabilitation augmented with either CBT (n = 84) or CR (n = 64). Both competitive and sheltered workplaces were used. Participants were assessed at baseline, at the end of the intervention period, and at 2-year follow-up. Results: At 2-year follow-up, 21.2% had obtained competitive employment. A further 25.3% had work placements in competitive workplaces. Significant improvements were found in global functioning, self-esteem, and depression during the intervention period, but no significant differences between the two intervention groups. High baseline global functioning and self-esteem, as well as positive change in these variables during the intervention period, were significantly associated with higher competitive employment outcome at 2-year follow-up. Conclusion: The results add to existing evidence that competitive employment is attainable for individuals with schizophrenia. High global functioning and self-esteem were strongly associated with competitive employment outcome.

Vocational rehabilitation for adults with psychotic disorders in a Scandinavian welfare society

BackgroundThis study examined the outcomes of a vocational rehabilitation program (The Job Management Program, JUMP) for persons with psychotic disorders based on close collaboration between health and welfare services.MethodsParticipants (N = 148) with broad schizophrenia spectrum disorders (age 18–65) were recruited from six counties in Norway. Three counties were randomized to vocational rehabilitation augmented with cognitive behaviour therapy (CBT), while the remaining three counties were randomized to vocational rehabilitation augmented with cognitive remediation (CR). This paper compares the vocational activity of the total group of JUMP participants with a treatment as usual group (N = 341), and further examines differences between the two JUMP interventions. Employment status (working/not working) was registered at the time of inclusion and at the end of the intervention period.ResultsThe total number of JUMP participants in any kind of vocational activity increased from 17 to 77% during the intervention. Of these, 8% had competitive employment, 36% had work placements in ordinary workplaces with social security benefits as their income, and 33% had sheltered work. The total number of working participants in the TAU group increased from 15.5 to 18.2%. The JUMP group showed significant improvements of positive (t = −2.33, p = 0.02) and general (t = −2.75, p = 0.007) symptoms of psychosis. Significant differences between the CBT and CR interventions were not demonstrated.ConclusionsThe study supports existing evidence that the majority of persons with broad schizophrenia spectrum disorders can cope with some kind of work, given that internal and external barriers are reduced. Those who wish to work should be offered vocational rehabilitation.Trial registrationClinicalTrials.gov Identifier: NCT01139502. Registered on 6 February 2010.

Vocational Functioning in Schizophrenia Spectrum Disorders: Does Apathy Matter?

Abstract While the influence of negative symptoms on vocational outcome is well documented, the specific contribution of apathy is less explored. The current study examined the influence of apathy on vocational outcome. A total of 148 participants were included in a vocational rehabilitation study, offering cognitive remediation (CR) or cognitive behavior therapy (CBT) to address work-related issues. Clinical and functional measures were assessed on inclusion and at posttreatment after approximately 10 months. The level of apathy was not related to the acquisition of work, but higher levels of apathy predicted fewer hours worked per week during the study. Previous employment predicted future employment, and higher education predicted more hours worked and higher score on the Work Behavior Inventory. The results did not differ across interventions. Thus, despite apathy, people with schizophrenia were able to work when the barriers to employment were addressed and adequate support was given.

An exploration of metacognitive beliefs and thought control strategies in bipolar disorder

BACKGROUND Metacognitive factors influence depression, but are largely unexplored in bipolar disorders. We examined i) differences in metacognitive beliefs and thought control strategies between individuals with bipolar disorder and controls, and ii) to what extent clinical characteristics were related to levels of metacognitive beliefs and thought control strategies in bipolar disorder. METHOD Eighty patients with bipolar disorder were assessed for age at onset of affective disorder, number of affective episodes, symptoms of mania and depression, metacognitive beliefs (MCQ-30) and thought control strategies (TCQ). Control subjects (N=166) completed MCQ-30 and TCQ. Factors impacting on metacognitive beliefs and thought control strategies were explored with multiple linear regressions. RESULTS Patients with bipolar disorder reported higher levels of unhelpful metacognitive beliefs and thought control strategies than controls. Metacognitive beliefs were mainly influenced by depressive symptoms, and age at onset of affective illness. Thought control strategies were mainly influenced by metacognitive beliefs and age at onset of affective illness. CONCLUSION Our findings suggest that metacognitive beliefs and control strategies are relevant in bipolar disorder. Depression and age at onset of affective disorder could contribute to metacognitive beliefs in bipolar disorder, and influence the use of thought control strategies. This indicates potential relationships that warrant further investigation for clinical relevance.

Validation of the Work Behavior Inventory

Abstract Background: The Work Behavior Inventory (WBI) was developed in the USA for the assessment of vocational functioning for people with severe mental illness. It is rated in a work setting by an employment specialist through observation and an interview with the immediate supervisor. Aims: The present study aims to examine the psychometric properties of the Norwegian version of the WBI. Methods: The participants (n = 148) of the Job Management Program (JUMP) study for psychotic disorders were assessed with the WBI around the fourth week of work. A principal component analysis identified three substantial factors. Results: The three corresponding scales were termed Social Skills revised, Work Quality revised and Compliance with work norms. The scales had a high internal consistency. Correlations with the Social Functioning Scale, education and previous work history supported the validity of the subscales. Conclusion: The results indicate that the Norwegian version of the WBI maintains good psychometric properties, and that vocational functioning can be reliably and validly assessed in a Norwegian setting. Clinical implications: There has been a lack of validated assessment tools for this group in Norway. Functional assessment with the WBI provides a comprehensive evaluation of the individuals’ strengths and challenges in the vocational setting, and provides goals for the vocational rehabilitation.

Cognitive remediation and occupational outcome in schizophrenia spectrum disorders: A 2 year follow-up study

Neurocognitive impairment is prominent in schizophrenia and a significant predictor of poor occupational outcomes. Vocational rehabilitation (VR) is frequently implemented to counteract high unemployment rates. Individuals with schizophrenia however face numerous challenges such as neurocognitive impairments and psychotic symptoms. Hence, augmenting VR to address illness-related factors may optimize occupational outcomes. The aim of this study was to examine the effects of Cognitive Remediation (CR) combined with VR(CR+VR) compared to techniques from Cognitive Behavioral Therapy (CBT) combined with VR(CBT+VR) on neurocognition and occupational functioning over a 2year period. A total of 131participants underwent assessment with the MATRICS Consensus Cognitive Battery (MCCB) at baseline, post treatment (after 10months) and follow-up (2years after randomization). Occupational status and number of hours worked were recorded at all assessment points. Both groups improved on several neurocognitive domains. All improvements were however in favor of the CR group. There was a significant increase in number of participants working and hours worked in both groups throughout the project period, with no between-group differences. Number of hours worked at follow-up was predicted by change in Working Memory and the Composite Score in the CR group. CR-augmented VR improved several domains, particularly Verbal Learning and Working Memory, which were central in the CR program. The combination of VR and CR or CBT thus enabled a significant proportion of participants to attain and maintain work.

T3. METACOGNITIVE BELIEFS IN SEVERE MENTAL DISORDERS

Abstract Background Affective dysregulation and psychotic experiences or symptoms often co-occur in the general population as well as in bipolar and psychotic disorders, suggesting a complex interplay. Early trauma is hypothesised to be important for the aetiology of both, and individuals with early traumatic experiences often develop disorders characterised by an admixture of affective and psychotic symptoms. Early emotional abuse seems to be particularly relevant for both disorders. Studies of common factors associated with affective dysregulation and psychosis in bipolar and psychotic disorders could help further theoretical understanding and tailor therapeutic interventions. Metacognitive beliefs – beliefs that outline the importance or consequence of thoughts – have been proposed as one possible common factor. Compared to healthy controls, patients with affective or psychotic disorders hold higher levels of metacognitive beliefs that could be maladaptive. Metacognitive beliefs have been linked to affective and/or psychotic diagnoses and symptoms in these disorders, and to early trauma in general. However, little is known about the specific relationships between symptoms of bipolar/psychotic disorders, early emotional abuse, and metacognitive beliefs. This project had three objectives: (1) to examine the prevalence of metacognitive beliefs in bipolar and psychotic disorders, compared to controls; (2) explore whether illness-related factors were linked to metacognitive beliefs; (3) examine if symptomatic responses (depression or positive symptoms) to early emotional abuse were mediated by metacognitive beliefs. Methods Patients with a bipolar or psychotic disorder, and healthy controls, were included through the on-going Thematically Organised Psychosis (TOP) Study in Oslo, Norway. Analyses included t-tests for group comparisons, regression analyses, and regression based mediation pathway analyses where the indirect effects were tested with bootstrapped confidence intervals. Results Patients with bipolar or psychotic disorders reported higher levels of metacognitive beliefs compared to controls. Metacognitive beliefs were significantly related to depression for all patients. Higher levels of metacognitive beliefs were also related to illness-factors related to a poorer long-term outcome, specifically an earlier age at onset of affective disorder in bipolar disorders, and poorer premorbid social adjustment in psychotic disorders. Metacognitive beliefs significantly mediated the relationship between early emotional abuse and depression. The combination of metacognitive beliefs and depression significantly mediated the relationship between early emotional abuse and positive symptoms. The mediation models explained a moderate amount of the variance in symptoms (R2 = .21 and .29) compared to direct models of early emotional abuse impacting on symptomatic responses directly (R2 = .04 and .03) Discussion Our results show that patients with bipolar or psychotic report higher levels of metacognitive beliefs compared to controls, and that such beliefs relate to current symptoms of depression in both patient groups. Our results also suggest that metacognitive beliefs relate to factors present before or at the onset of illness, which are often linked to a poorer long-term outcome in the disorders. Further, our findings suggest that in regards to early emotional abuse, metacognitive beliefs could play a role in an affective pathway to psychosis. Metacognitive beliefs could thus be relevant treatment targets in regards to depression and positive symptoms in bipolar and psychotic disorders.

Metacognitive beliefs mediate the effect of emotional abuse on depressive and psychotic symptoms in severe mental disorders

BACKGROUND Early trauma is linked to higher symptom levels in bipolar and psychotic disorders, but the translating mechanisms are not well understood. This study examines whether the relationship between early emotional abuse and depressive symptoms is mediated by metacognitive beliefs about thoughts being uncontrollable/dangerous, and whether this pathway extends to influence positive symptoms. METHOD Patients (N = 261) with psychotic or bipolar disorders were assessed for early trauma experiences, metacognitive beliefs, and current depression/anxiety and positive symptoms. Mediation path analyses using ordinary least-squares regressions tested if the effect of early emotional abuse on depression/anxiety was mediated by metacognitive beliefs, and if the effect of early emotional abuse on positive symptoms was mediated by metacognitive beliefs and depression/anxiety. RESULTS Metacognitive beliefs about thoughts being uncontrollable/dangerous significantly mediated the relationship between early emotional abuse and depression/anxiety. Metacognitive beliefs and depression/anxiety significantly mediated the relationship between early emotional abuse and positive symptoms. The models explained a moderate amount of the variance in symptoms (R 2 = 0.21-0.29). CONCLUSION Our results indicate that early emotional abuse is relevant to depression/anxiety and positive symptoms in bipolar and psychotic disorders, and suggest that metacognitive beliefs could play a role in an affective pathway to psychosis. Metacognitive beliefs could be relevant treatment targets with regards to depression/anxiety and positive symptoms in bipolar and psychotic disorders.
