Evidence-based treatment of schizophrenia.

People with schizophrenia can be helped greatly with pharmacologic and psychosocial interventions that are known to be effective. Several interventions are now supported by research: use of medications following specific guidelines, training in illness self-management, case management based on principles of assertive community treatment, family psychoeducation, supported employment, and integrated substance abuse treatment. However, few patients actually receive these evidence-based interventions because they are not provided in routine mental health settings. Therefore, implementing effective treatments in mental health treatment programs is a critical challenge for the field. We review the six areas of evidence-based treatment of schizophrenia, as well as knowledge regarding implementation of mental health programs in routine practice settings.

An ethnographic study of the longitudinal course of substance abuse among people with severe mental illness.

A two-year ethnography conducted among 16 dually diagnosed clients yielded two longitudinal findings. First, four "positive quality of life" factors were strongly correlated with clients' efforts to cease using addictive substances: (1) regular engagement in an enjoyable activity; (2) decent, stable housing; (3) a loving relationship with someone sober who accepts the person's mental illness; and (4) a positive, valued relationship with a mental health professional. Second, the study revealed that five "negative background factors" in participants' childhood homes were predictive of long-term continuation of substance use: (1) substance abuse in childhood home, (2) childhood household in dire poverty, (3) "non-functional" household members, (4) reporting of abuse imputed to care-givers, and (5) serious mental illness in household. The implications of these findings for treatment are discussed.

Psychosocial approaches to dual diagnosis.

Recent research elucidates many aspects of the problem of co-occurring substance use disorder (SUD) in patients with severe mental illness, which is often termed dual diagnosis. This paper provides a brief overview of current research on the epidemiology, adverse consequences, and phenomenology of dual diagnosis, followed by a more extensive review of current approaches to services, assessment, and treatment. Accumulating evidence shows that comorbid SUD is quite common among individuals with severe mental illness and that these individuals suffer serious adverse consequences of SUD. The research further suggests that traditional, separate services for individuals with dual disorders are ineffective, and that integrated treatment programs, which combine mental health and substance abuse interventions, offer more promise. In addition to a comprehensive integration of services, successful programs include assessment, assertive case management, motivational interventions for patients who do not recognize the need for substance abuse treatment, behavioral interventions for those who are trying to attain or maintain abstinence, family interventions, housing, rehabilitation, and psychopharmacology. Further research is needed on the organization and financing of dual-diagnosis services and on specific components of the integrated treatment model, such as group treatments, family interventions, and housing approaches.

The effects of clozapine on alcohol and drug use disorders among patients with schizophrenia.

Several case studies indicate that clozapine use is associated with reductions in the use of nicotine, alcohol, or illicit drugs. Although not designed to assess clozapine, this study explored a posteriori the effects of clozapine on alcohol and drug use disorders among schizophrenia patients. Among 151 patients with schizophrenia or schizoaffective disorder and co-occurring substance use disorder who were studied in a dual-disorder treatment program, 36 received clozapine during the study for standard clinical indications. All participants were assessed prospectively at baseline and every 6 months over 3 years for psychiatric symptoms and substance use. Alcohol-abusing patients taking clozapine experienced significant reductions in severity of alcohol abuse and days of alcohol use while on clozapine. For example, they averaged 54.1 drinking days during 6-month intervals while off clozapine and 12.5 drinking days while on clozapine. They also improved more than patients who did not receive clozapine. At the end of the study, 79.0 percent of the patients on clozapine were in remission from alcohol use disorder for 6 months or longer, while only 33.7 percent of those not taking clozapine were remitted. Findings related to other drugs in relation to clozapine were also positive but less clear because of the small number of patients with drug use disorders. This study was limited by the naturalistic design and the lack of prospective, standardized measures of clozapine use. The use of clozapine by patients with co-occurring substance disorders deserves further study in randomized clinical trials.

Self-esteem as an outcome measure in studies of vocational rehabilitation for adults with severe mental illness.

OBJECTIVE: Self-esteem is widely used as an outcome variable in studies of psychiatric rehabilitation, based on the assumption that improved functional status leads to higher self-esteem. Little is known, however, about the determinants of self-esteem among adults with severe mental illness. The utility of a popular measure of global self-esteem-the Rosenberg Self-Esteem Scale-as an outcome measure was examined in this population. METHODS: A total of 143 participants enrolled in a study of vocational rehabilitation were assessed at baseline and six, 12, and 18 months later using measures of self-esteem, symptoms, life satisfaction, work status, housing status, and total income. RESULTS: Scores on the Rosenberg Self-Esteem Scale did not vary with work status or other functional outcomes but instead were strongly related to measures of life satisfaction and affective symptoms. CONCLUSIONS: The hypothesis that working leads to improved self-esteem for people with severe mental illness was not supported. For this population, self-esteem, as measured by the Rosenberg Self-Esteem Scale, appears to be a relatively stable trait that reflects general life satisfaction and affective symptoms rather than objective functional status.

A randomized clinical trial of supported employment for inner-city patients with severe mental disorders.

BACKGROUND: This experiment evaluated the effectiveness of 2 approaches to vocational services for persons with severe mental disorders: (1) individual placement and support (IPS), in which employment specialists within the mental health center help patients to obtain competitive jobs and provide ongoing support, and (2) enhanced vocational rehabilitation (EVR), in which stepwise vocational services are delivered by rehabilitation agencies. METHODS: One hundred fifty-two unemployed, inner-city patients with severe mental disorders who expressed interest in competitive employment were randomly assigned to IPS or EVR and followed up for 18 months. Following diagnostic assessment, participants were assessed with standardized measures of work, income, self-esteem, quality of life, symptoms, and hospitalization at baseline and at 6-, 12-, and 18-month follow-up evaluations. Employment was tracked monthly and job satisfaction every 2 months. RESULTS: During the 18-month study, participants in the IPS program were more likely to become competitively employed (60.8% vs 9.2%) and to work at least 20 hours per week in a competitive job (45.9% vs 5.3%), whereas EVR participants had a higher rate of participation in sheltered employment (71.1% vs 10.8%). Total earnings, job satisfaction, and nonvocational outcomes were similarly improved for both groups. CONCLUSION: The IPS model of supported employment is more effective than standard, stepwise EVR approaches for achieving competitive employment, even for inner-city patients with poor work histories and multiple problems.

Research on the individual placement and support model of supported employment.

This paper reviews research on the Individual Placement and Support (IPS) model of supported employment for people with severe mental illness. Current evidence indicates that IPS supported employment is a more effective approach for helping people with psychiatric disabilities to find and maintain competitive employment than rehabilitative day programs or than traditional, stepwise approaches to vocational rehabilitation. There is no evidence that the rapid-job-search, high-expectations approach of IPS produces untoward side effects. IPS positively affects satisfaction with finances and vocational services, but probably has minimal impact on clinical adjustment. The cost of IPS is similar to the costs of other vocational services, and cost reductions may occur when IPS displaces traditional day treatment programs. Future research should be directed at efforts to enhance job tenure and long-term vocational careers.

HIV risk factors among people with severe mental illness in urban and rural areas.

No studies have reported HIV risk behavior in rural populations with severe mental illness. A total of 84 rural patients with severe mental illness in New Hampshire and 158 urban patients in Baltimore were interviewed about their HIV risk behavior in the past six months using the Risk Assessment Battery, a 38-item structured clinical interview. Rates of sexual and drug risk behavior among rural patients were significantly lower than among urban patients. Regression analyses showed that urban setting, younger age, never having been married, and a bisexual or gay orientation significantly predicted higher HIV risk scores. The differences in risk behaviors may reflect urban-rural differences in drug availability and sexual practices.

Fidelity to assertive community treatment and client outcomes in the New Hampshire dual disorders study.

OBJECTIVE: The study examined the association between fidelity of programs to the assertive community treatment model and client outcomes in dual disorders programs. METHODS: Assertive community treatment programs in the New Hampshire dual disorders study were classified as low-fidelity programs (three programs) or high-fidelity programs (four programs) based on extensive longitudinal process data. The study included 87 clients with a dual diagnosis of severe mental illness and a comorbid substance use disorder. Sixty-one clients were in the high-fidelity programs, and 26 were in the low-fidelity programs. Client outcomes were examined in the domains of substance abuse, housing, psychiatric symptoms, functional status, and quality of life, based on interviews conducted every six months for three years. RESULTS: Clients in the high-fidelity assertive community treatment programs showed greater reductions in alcohol and drug use and attained higher rates of remission from substance use disorders than clients in the low-fidelity programs. Clients in high-fidelity programs had higher rates of retention in treatment and fewer hospital admissions than those in low-fidelity programs. No differences between groups were found in length of hospital stays and other residential measures, psychiatric symptoms, family and social relations, satisfaction with services, and overall life satisfaction. CONCLUSIONS: Faithful implementation of, and adherence to, the assertive community treatment model for persons with dual disorders was associated with superior outcomes in the substance use domain. The findings underscore the value of measures of model fidelity, and they suggest that local modifications of the assertive community treatment model or failure to comply with it may jeopardize program success.

Conduct disorder, antisocial personality disorder and substance use disorders in schizophrenia and major affective disorders.

OBJECTIVE: To examine the relationships between childhood conduct disorder (CD), antisocial personality disorder (ASPD) and substance use disorders (substance abuse or substance dependence) in psychiatric patients with severe mental illness. METHOD: Substance use-related problems on screening instruments, lifetime and recent prevalence of substance use disorders, and family history of substance use disorder were evaluated in four groups of 293 patients with mainly schizophrenia-spectrum and major affective disorders: No ASPD/CD, CD Only, Adult ASPD Only, Full ASPD. RESULTS: Full ASPD was strongly related to all measures of substance use problems and disorders, as well as fathers' history of substance use disorder. The odds ratios for Full ASPD and substance use disorders ranged between 3.96 (lifetime cannabis use disorder) to 11.35 (recent cocaine use disorder). To a lesser extent, patients with CD Only or Adult ASPD Only were also at increased risk for having substance use disorders compared to the No ASPD/CD patients. CONCLUSIONS: Childhood CD and adult ASPD represent significant risk factors for substance use disorders in patients with schizophrenia-spectrum and major affective disorders. Considering other research indicating that CD and ASPD have a higher prevalence in patients with severe mental illness, the present findings suggest that CD and ASPD could reflect a common factor that independently increases patients' vulnerability to both psychiatric and substance use disorders.

Complications of severe mental illness related to alcohol and drug use disorders.

In this chapter we review research on the relationships between substance use disorder and 11 domains of adjustment for people with severe mental illness. Studies are divided into correlational research and prospective, longitudinal research, with greater weight given to those in the latter category. The weight of the evidence indicates that substance abuse severely complicates severe mental illness in the following domains: relapse of psychiatric illness, hospitalization, disruptive behavior, familial problems, residential instability, decreased functional status, HIV infection, and medication noncompliance. We discuss the limits of causal inference in these studies and the possible mechanisms that relate substance abuse to various complications.

Benefits and costs of supported employment from three perspectives.

Administrators, consumers, and policy makers are increasingly interested in supported employment as a way of helping persons with severe mental illness get and keep competitive jobs. However, in an atmosphere of increased expectations for performance and declining public financing, administrators want to know the costs and benefits of different approaches before they reallocate scarce treatment or rehabilitative dollars. This article discusses the net benefits of two approaches to supported employment that were compared in a randomized trial: Individual Placement and Support (IPS) and Group Skills Training (GST). The authors analyze costs and benefits from societal, government, and consumer perspectives. Although a previous analysis showed that IPS participants were significantly more likely to find work, worked more hours, and had higher earnings, net benefits of the two programs were not significantly different. The authors also discuss some of the strengths and weaknesses of cost-benefit analysis in mental health care and suggest future directions for policy and research.

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.

Gender differences in homeless persons with schizophrenia and substance abuse.

The purpose of this study was to test the generalizability of previous research on gender differences between men and women with co-occurring schizophrenia and substance abuse. One hundred eight patients with schizophrenia or schizo-affective disorder involved in a study of treatment for homeless persons were interviewed for information regarding substance use, social functioning and support, comorbid disorders, victimization, medical illness, and legal troubles. We found that women had more children and were more socially connected than men. Women also had higher rates of sexual and physical victimization, comorbid anxiety and depression, and medical illness than men. We conclude that homeless women with dual disorders, like women with substance use disorders in the general population, have distinct characteristics, vulnerabilities, and treatment needs compared with men. In addition to comprehensive treatment of psychiatric and substance use disorders, gender-specific services should be developed, including prevention and treatment of victimization and related problems as well as help with accessing medical services.

A research induction group for clients entering a mental health research project: a replication study.

Through education and discussion, the research induction group introduces mental health clients to participation in a research study. The purpose is to help clients to understand fully the clinical and research procedures involved in the study so that they can make a truly informed decision about whether or not to participate. This study replicated a previous study in showing that the research induction group resulted in informed decision-making, high rates of participation in the clinical services and in the research, and high rates of satisfaction with both vocational services and research procedures.
