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.

The Hartford study of supported employment for persons with severe mental illness.

The authors compared 3 approaches to vocational rehabilitation for severe mental illness (SMI): the individual placement and support (IPS) model of supported employment, a psychosocial rehabilitation (PSR) program, and standard services. Two hundred four unemployed clients (46% African American, 30% Latino) with SMI were randomly assigned to IPS, PSR, or standard services and followed for 2 years. Clients in IPS had significantly better employment outcomes than clients in PSR and standard services, including more competitive work (73.9% vs. 18.2% vs. 27.5%, respectively) and any paid work (73.9% vs. 34.8% vs. 53.6%, respectively). There were few differences in nonvocational outcomes between programs. IPS is a more effective model than PSR or standard brokered vocational services for improving employment outcomes in clients with SMI.

Work, Recovery, and Comorbidity in Schizophrenia: A Randomized Controlled Trial of Cognitive Remediation

Employment is central to the concept of recovery in severe mental illness. However, common comorbid conditions present significant obstacles to consumers seeking employment and benefiting from vocational rehabilitation. We review research on the effects of three common comorbid conditions on work and response to vocational rehabilitation, including cognitive impairment, substance abuse, and medical conditions, followed by research on vocational rehabilitation. We then present the results of a randomized controlled trial evaluating the effects of adding cognitive remediation to a vocational rehabilitation program compared with vocational rehabilitation alone in 34 consumers with severe mental illness. Consumers who received both cognitive remediation and vocational rehabilitation demonstrated significantly greater improvements on a cognitive battery over 3 months than those who received vocational rehabilitation alone and had better work outcomes over the 2-year follow-up period. Substance abuse was associated with worse employment outcomes, but did not interact with treatment group, whereas medical comorbidity was not related to work outcomes. More research is warranted to evaluate the interactions between substance abuse and medical comorbidity with vocational rehabilitation and cognitive remediation.

The effects of yoga on mood in psychiatric inpatients.

The effects of yoga on mood were examined in 13 psychiatric inpatients at New Hampshire Hospital. Participants completed the Profile of Mood States (POMS) prior to and following participation in a yoga class. Analyses indicated that participants reported significant improvements on all five of the negative emotion factors on the POMS, including tension-anxiety, depression-dejection, anger-hostility, fatigue-inertia, and confusion-bewilderment. There was no significant change on the sixth POMS factor, vigor-activity. Improvements in mood were not related to gender or diagnosis. The results suggest that yoga was associated with improved mood, and may be a useful way of reducing stress during inpatient psychiatric treatment.

Supported employment, job preferences, job tenure and satisfaction

The relationships between job preferences, job satisfaction and job tenure were examined in a sample of 204 unemployed clients with severe mental illness randomly assigned to one of three vocational rehabilitation programs and followed for 2 years. These were the Individual Placement and Support (IPS) model of supported employment, a psychiatric rehabilitation program (PSR) and standard services (Standard). For clients in the IPS program, those who obtained jobs that matched their preemployment preferences for type of work desired reported higher levels of job satisfaction and had longer job tenures than clients who obtained jobs that did not match their preferences. For clients in the PSR or Standard programs, job preferences were not related to job tenure or satisfaction. The findings replicate previous research in this area, and suggest that helping clients obtain work that matches their job preferences is an important ingredient of success in supported employment programs.The relationships between job preferences, job satisfaction and job tenure were examined in a sample of 204 unemployed clients with severe mental illness randomly assigned to one of three vocational rehabilitation programs and followed for 2 years.

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.

The trauma of psychosis: Posttraumatic stress disorder and recent onset psychosis

Clinical investigators have argued that the experience of a recent onset of psychosis is an event of such severity that it can lead to posttraumatic stress disorder (PTSD), or at least to PTSD symptoms. The traumagenic elements of the psychotic experience may relate to the distressing nature of psychotic symptoms, components of treatment, or both. However, this hypotheses has not been fully empirically evaluated. In particular, the importance of the DSM-IV A1 (perception of threat) and A2 (negative emotion at time of event) criteria for a traumatic event due to a psychotic episode has not been assessed. To address this question, 38 clients in treatment for recent onset of psychosis were interviewed to identify distressing experiences related to the episode, with PTSD assessed (including A1/A2 criteria) related to those events. More than one-half of the participants reported intense distress related to psychotic symptoms or treatment experiences, with 66% meeting symptom criteria for the PTSD syndrome (regardless of A1/A2), and 39% meeting full diagnostic criteria for PTSD (including A1/A2). Both participants with the PTSD syndrome and full PTSD reported more problems in daily functioning and more severe symptoms than those without PTSD. Participants with the PTSD syndrome were also more likely to have an integrative rather than sealing over coping style compared to those without the PTSD syndrome. The results suggest that individuals with PTSD symptoms related to a recent onset of psychosis may benefit from intervention designed to help them integrate their experience into their lives and address potentially stigmatizing beliefs that could contribute to distress and impaired functioning.

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.

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.

Rural and urban differences in patients with a dual diagnosis.

OBJECTIVES To evaluate the differences between two cohorts of patients with severe mental illness (schizophrenia-spectrum or bipolar disorder) and co-occurring substance-use disorders, living in either predominantly rural areas or urban areas. METHODS Two study groups of patients with a dual diagnosis, recruited using the same criteria, were evaluated, including 225 patients from New Hampshire and 166 patients from two cities in Connecticut. The two study groups were compared on demographic characteristics, housing, legal problems, psychiatric and substance use diagnoses, substance use and abuse, psychiatric symptoms, and quality of life. RESULTS Patients in the Connecticut study group had higher rates of cocaine-use disorder, more involvement in the criminal justice system, more homelessness, and were more likely to be from minority backgrounds. The Connecticut group also had a higher proportion of patients with schizophrenia and more severe symptoms, as well as lower rates of marriage, educational attainment, and work than the New Hampshire study group. Alcohol-use disorder was higher in the New Hampshire group. Subsequent analyses within the Connecticut group indicated that although African American patients had higher rates of cocaine-use disorder than white patients, cocaine disorder and not minority status was most strongly related to criminal involvement and homelessness. CONCLUSIONS Because of the substances abused and the greater degree of psychiatric illness severity, patients with a dual diagnosis who are living in urban areas may require greater ancillary services, such as residential programs, Assertive Community Treatment, and jail diversion programs in order to treat their disorders successfully.
