Does competitive employment improve nonvocational outcomes for people with severe mental illness

The authors examined the cumulative effects of work on symptoms, quality of life, and self-esteem for 149 unemployed clients with severe mental illness receiving vocational rehabilitation. Nonvocational measures were assessed at 6-month intervals throughout the 18-month study period, and vocational activity was tracked continuously. On the basis of their predominant work activity over the study period, participants were classified into 4 groups: competitive work, sheltered work, minimal work, and no work. The groups did not differ at baseline on any of the nonvocational measures. Using mixed effects regression analysis to examine rates of change over time, the authors found that the competitive work group showed higher rates of improvement in symptoms; in satisfaction with vocational services, leisure, and finances; and in self-esteem than did participants in a combined minimal work-no work group. The sheltered work group showed no such advantage.

A Randomized Controlled Trial of Cognitive-Behavioral Treatment for Posttraumatic Stress Disorder in Severe Mental Illness

A cognitive-behavioral therapy (CBT) program for posttraumatic stress disorder (PTSD) was developed to address its high prevalence in persons with severe mental illness receiving treatment at community mental health centers. CBT was compared with treatment as usual (TAU) in a randomized controlled trial with 108 clients with PTSD and either major mood disorder (85%) or schizophrenia or schizoaffective disorder (15%), of whom 25% also had borderline personality disorder. Eighty-one percent of clients assigned to CBT participated in the program. Intent-to-treat analyses showed that CBT clients improved significantly more than did clients in TAU at blinded posttreatment and 3- and 6-month follow-up assessments in PTSD symptoms, other symptoms, perceived health, negative trauma-related beliefs, knowledge about PTSD, and case manager working alliance. The effects of CBT on PTSD were strongest in clients with severe PTSD. Homework completion in CBT predicted greater reductions in symptoms. Changes in trauma-related beliefs in CBT mediated improvements in PTSD. The findings suggest that clients with severe mental illness and PTSD can benefit from CBT, despite severe symptoms, suicidal thinking, psychosis, and vulnerability to hospitalizations.

Work and nonvocational domains of functioning in persons with severe mental illness: a longitudinal analysis.

In this study we sought to understand the relationship between obtaining competitive employment and changes in nonvocational domains of functioning (symptoms, substance abuse, hospitalizations, self-esteem, quality of life) in persons with severe mental illness. A group of 143 unemployed patients participating in a study of vocational rehabilitation programs were assessed in nonvocational areas of functioning at baseline and 6, 12, and 18 months later. Statistical analyses examined the relationship between work status at the follow-up assessments and nonvocational functioning, controlling for baseline levels of nonvocational variables. Patients who were working at follow-up tended to have lower symptoms (particularly thought disorder and affect on the Brief Psychiatric Rating Scale), higher Global Assessment Scores, better self-esteem, and more satisfaction with their finances and vocational services than unemployed patients. Employment is associated with better functioning in a range of different nonvocational domains, even after controlling for baseline levels of functioning.

Job Terminations Among Persons with Severe Mental Illness Participating in Supported Employment

For persons with psychiatric disabilities, maintaining a job is often more difficult than acquiring a job. A large proportion of jobs end unsatisfactorily. This study explored job terminations among 63 persons with severe mental illness who participated in competitive jobs through supported employment programs. More than half of the job terminations were unsatisfactory, defined as the client quitting without having other job plans or being fired. Baseline ratings of demographic and clinical characteristics, preemployment skills training, and early ratings of job satisfaction and work environment did not predict unsatisfactory terminations. Clients with better work histories were less likely to experience unsatisfactory terminations. In addition, unsatisfactory terminations were associated retrospectively with multiple problems on the job that were related to interpersonal functioning, mental illness, dissatisfaction with jobs, quality of work, medical illnesses, dependability, and substance abuse. These results suggest that supported employment programs need to address job maintenance with interventions that identify and address different types of difficulties as they arise on the job.

A randomized controlled trial of cognitive remediation among inpatients with persistent mental illness.

OBJECTIVE This study evaluated the feasibility and efficacy of a cognitive remediation program in improving cognitive and work functioning for intermediate- to long-stay psychiatric inpatients. METHODS Eighty-five inpatients with predominantly DSM-IV-defined schizophrenia were randomly assigned to cognitive remediation or to a control condition. The cognitive remediation program consisted of 24 hours of computerized practice over a 12-week period and a weekly discussion group to facilitate transfer of cognitive skills to daily activities. A computer control group received similar hours of staff and computer exposure without cognitive training exercises. A comprehensive neuropsychological battery was administered at baseline and posttreatment. Symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS) at baseline, midtreatment (six weeks), and posttreatment (12 weeks) and at six- and 12-month follow-ups. Work functioning was tracked during a 12-month follow-up period. RESULTS The average number of 45-minute sessions completed was 23. Patients in the cognitive remediation group demonstrated significantly greater improvements over three months than the control group in the composite measure of overall cognitive functioning, psychomotor speed, and verbal learning. In addition, patients who received cognitive remediation worked more weeks than the control group over the 12-month follow-up period. Patients in both groups showed significant and comparable improvements over the follow-up period on the positive, activation, and depression subscales of the PANSS. CONCLUSIONS Cognitive remediation was a feasible treatment for this group of inpatients and more effective at improving cognitive functioning than a computer control intervention. Longer-term follow-up indicated that cognitive remediation was associated with better work outcomes, suggesting benefits in psychosocial functioning.

What Predicts Supported Employment Program Outcomes

Numerous state systems and local mental health and vocational rehabilitation programs are currently attempting to implement supported employment. This cross-sectional survey of 26 mental health agencies, partnering with federal-state vocational rehabilitation, identified differences in access to supported employment services and rates of competitive employment (efficiency) as well as predictors of access and efficiency. Access varied from 2 to 100% and was related to the percentage of supported employment specialists per consumers with serious mental illness served by the mental health agency (funding). Efficiency varied from 7 to 75% and was related to implementation of the critical components of evidence-based supported employment and to the local unemployment rate. To help mental health clients achieve their employment goals, state systems and local programs should address consolidation of resources in supported employment and the quality of implementation of supported employment.

Relationships between symptoms of schizophrenia and substance abuse

Previous work posits that severity of substance abuse and severity of schizophrenic symptoms should be linked by either or both of two mechanisms: self-regulation of symptoms and drug-induced exacerbation of symptoms. Research on these relationships has yielded mixed results. We examined the interrelationships of schizophrenic symptoms and substance abuse in 172 patients with co-occurring disorders. Relationships were weak or nonexistent, without any consistent pattern. Our findings do not support the view that substances are used to self-regulate symptoms. In addition, our results suggest that substance abuse may lead to higher rates of institutionalization through mechanisms other than by exacerbating symptoms.

Clinically Significant Improved Fitness and Weight Loss Among Overweight Persons With Serious Mental Illness

OBJECTIVE The objective of this study was to evaluate the effectiveness of a fitness health mentor program (In SHAPE) in improving physical fitness and weight loss among overweight and obese adults with serious mental illness. METHODS A randomized controlled trial was conducted with 133 persons with serious mental illness and a body mass index (BMI) >25 who were assigned either to the In SHAPE program (one year of weekly sessions with a fitness trainer plus a fitness club membership) or to one year of fitness club membership and education. Assessments were conducted at baseline and three, six, nine, and 12 months later. RESULTS Participants had a mean baseline weight of 231.8±54.8 pounds and a mean BMI of 37.6±8.2. At 12-month follow-up, In SHAPE (N=67) compared with fitness club membership and education (N=66) was associated with three times greater fitness club attendance, twice as much participation in physical exercise, greater engagement in vigorous physical activity, and improvement in diet. Twice the proportion of participants (40% versus 20%) achieved clinically significant improvement in cardiorespiratory fitness (>50 m on the six-minute walk test). Weight loss and BMI did not differ between groups. Among In SHAPE participants, 49% achieved either clinically significant increased fitness or weight loss (5% or greater), and 24% achieved both clinically significant improved fitness and weight loss. CONCLUSIONS The In SHAPE program achieved clinically significant reduction in cardiovascular risk for almost one-half of participants at 12 months. Although the intervention showed promise in improving fitness, optimizing weight loss may require additional intensive, multicomponent dietary interventions.

A cognitive behavioral therapy for co-occurring substance use and posttraumatic stress disorders

Co-occurring posttraumatic stress disorder (PTSD) is prevalent in addiction treatment programs and a risk factor for negative outcomes. Although interventions have been developed to address substance use and PTSD, treatment options are needed that are effective, well tolerated by patients, and potentially integrated with existing program services. This paper describes a cognitive behavioral therapy (CBT) for PTSD that was adapted from a treatment for persons with severe mental illnesses and PTSD in community mental health settings. The new adaptation is for patients in community addiction treatment with co-occurring PTSD and substance use disorders. In this study, 5 community therapists delivered the CBT for PTSD. Outcome data are available on 11 patients who were assessed at baseline, post-CBT treatment, and at a 3-month follow-up post-treatment. Primary outcomes were substance use, PTSD severity, and retention, of which all were favorable for patients receiving the CBT for PTSD.

Posttraumatic Stress Disorder, Supported Employment, and Outcomes in People with Severe Mental Illness

OBJECTIVE To evaluate whether posttraumatic stress disorder (PTSD) is related to outcomes in persons with severe mental illness (SMI) participating in a study of vocational rehabilitation programs. BACKGROUND PTSD is a common comorbid disorder in people with SMI, but it is unknown whether PTSD interferes with the ability to benefit from rehabilitation programs such as supported employment. METHODS The relationships between PTSD and symptoms, health, quality of life, and work outcomes was examined in 176 clients with SMI participating in a 2-year randomized controlled trial of three vocational rehabilitation programs: supported employment based on the Individual Placement and Support model, a psychosocial rehabilitation program based on transitional employment, and standard services. RESULTS The overall rate of current PTSD in the sample was 16 percent. Compared with clients without PTSD, clients with PTSD had more severe psychiatric symptoms, worse reported health, lower self-esteem, and lower subjective quality of life. Clients with PTSD who participated in the Individual Placement and Support model (the most effective vocational model of the three studied) also had worse employment outcomes over the 2-year study period than clients without PTSD, with lower rates of competitive work, fewer hours worked, and fewer wages earned. Employment outcomes did not differ between clients with PTSD versus without PTSD in the other two vocational rehabilitation approaches. CONCLUSION The findings suggest that PTSD may contribute to worse work outcomes in clients participating in supported employment programs. Effective treatment of these clients with PTSD may improve their ability to benefit from supported employment.
