A review of treatments for people with severe mental illnesses and co-occurring substance use disorders.

Several interventions for people with co-occurring severe mental illnesses and substance use disorders have emerged since the early 1980s. This paper reviews 26 controlled studies of psychosocial interventions published or reported in the last 10 years (1994-2003). Though most studies have methodological weaknesses, the cumulative evidence from experimental and quasi-experimental research supports integrating outpatient mental health and substance abuse treatments into a single, cohesive package. Effective treatments are also individualized to address personal factors and stage of motivation, e.g., engaging people in services, helping them to develop motivation, and helping them to develop skills and supports for recovery. Accumulating evidence from quasi-experimental studies also suggests that integrated residential treatment, especially long-term (one year or more) treatment, is helpful for individuals who do not respond to outpatient dual disorders interventions. Current research aims to refine and test individual components and combinations of integrated treatments.

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.

Randomized trial of cognitive-behavioral therapy for chronic posttraumatic stress disorder in adult female survivors of childhood sexual abuse.

The authors conducted a randomized clinical trial of individual psychotherapy for women with posttraumatic stress disorder (PTSD) related to childhood sexual abuse (n = 74), comparing cognitive-behavioral therapy (CBT) with a problem-solving therapy (present-centered therapy; PCT) and to a wait-list (WL). The authors hypothesized that CBT would be more effective than PCT and WL in decreasing PTSD and related symptoms. CBT participants were significantly more likely than PCT participants to no longer meet criteria for a PTSD diagnosis at follow-up assessments. CBT and PCT were superior to WL in decreasing PTSD symptoms and secondary measures. CBT had a significantly greater dropout rate than PCT and WL. Both CBT and PCT were associated with sustained symptom reduction in this sample.

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.

Fidelity Outcomes in the National Implementing Evidence-Based Practices Project

OBJECTIVE This article presents fidelity outcomes for five evidence-based practices that were implemented in routine public mental health settings in the National Implementing Evidence-Based Practices Project. METHODS Over a two-year period 53 community mental health centers across eight states implemented one of five evidence-based practices: supported employment, assertive community treatment, integrated dual disorders treatment, family psychoeducation, and illness management and recovery. An intervention model of practice dissemination guided the implementation. Each site used both human resources (consultant-trainers) and material resource (toolkits) to aid practice implementation and to facilitate organizational changes. External assessors rated fidelity to the evidence-based practice model every six months from baseline to two years. RESULTS More than half of the sites (29 of 53, or 55%) showed high-fidelity implementation at the end of two years. Significant differences in fidelity emerged by evidence-based practice. Supported employment and assertive community treatment had higher fidelity scores at baseline and across time. Illness management and recovery and integrated dual disorders treatment had lower scores on average throughout. In general, evidence-based practices showed an increase in fidelity from baseline to 12 months, with scores leveling off between 12 and 24 months. CONCLUSIONS Most mental health centers implemented these evidence-based practices with moderate to high fidelity. The critical time period for implementation was approximately 12 months, after which few gains were made, although sites sustained their attained levels of evidence-based practice fidelity for another year.

Integrated Treatment for Dually Diagnosed Homeless Adults

This study examined the effects of integrating mental health, substance abuse, and housing interventions for homeless persons with co-occurring severe mental illness and substance use disorder. With the use of a quasi-experimental design, integrated treatment was compared with standard treatment for 217 homeless, dually diagnosed adults over an 18-month period. The integrated treatment group had fewer institutional days and more days in stable housing, made more progress toward recovery from substance abuse, and showed greater improvement of alcohol use disorders than the standard treatment group. Abuse of drugs other than alcohol (primarily cocaine) improved similarly for both groups. Secondary outcomes, such as psychiatric symptoms, functional status, and quality of life, also improved for both groups, with minimal group differences favoring integrated treatment.

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.

A scale for assessing the stage of substance abuse treatment in persons with severe mental illness

Substance abuse is common among persons with severe mental illness, but few measures exist for clinicians to evaluate treatment progress. The Substance Abuse Treatment Scale (SATS) combines a motivational hierarchy with explicit substance use criteria to form an eight-stage model of the recovery process. Data are presented supporting the reliability and validity of the SATS, based on its use in a community-based sample of persons with dual disorders. The SATS can be used as either a process or an outcome measure, for individuals or for groups, and its value in making explicit the stages of substance abuse treatment is discussed.

Factor structure of the Brief Psychiatric Rating Scale in schizophrenia

The authors report the results of a confirmatory factor analysis of symptoms assessed with the Brief Psychiatric Rating Scale (BPRS) in a sample of 474 patients with schizophrenia, replicated in an independent sample of 327 patients. The most commonly used 5-factor solution for the BPRS fit the data poorly. Exploratory factor analyses performed on the first sample led to the specification of a 4-factor model that included Thought Disturbance, Anergia, Affect, and Disorganization. Confirmatory factor analyses on both samples indicated that the 4-factor model fit the data better than the previously proposed factor structure for the BPRS. Future research on the BPRS in schizophrenia should use the 4-factor model identified in this study.

Rehabilitative day treatment vs. supported employment: I. Vocational outcomes

Day treatment remains a core component in many community mental health programs for persons with severe mental disorders throughout the United States. Many other mental health centers are moving away from day treatment toward psychosocial and vocational rehabilitation programs. Empirical research directly comparing these two systems of organizing outpatient services is needed. In this study the authors compared a rehabilitative day treatment program in one small city with a similar program in a nearby city that changed from day treatment to a supported employment model. Clients who were enrolled in community support services during a baseline year prior to the change and during a follow-up year after the change (71 in the program that changed and 112 in the other) were evaluated during both intervals. In the program that changed, competitive employment improved from 25.4% to 39.4% for all clients, and from 33.3% to 55.6% for those clients who had been regular attenders of day treatment during the baseline. Hours worked and wages earned similarly improved after the program change. For all work variables, clients who had not worked during the baseline year accounted for the improvements in outcome. Meanwhile, employment remained stable in the day treatment program. No negative outcomes were detected. These results indicate that eliminating day treatment and replacing it with a supported employment program can improve integration into competitive jobs in the community.
