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 generalized signal detection model to predict rational variation in base rate use.
The predominant models of rational behavior currently used to analyze a large class of experiments imply that subjects neglect or place insufficient weight on base rates when making probabilistic judgments. We argue that the evidence is inadequate for this conclusion because the models make needlessly restrictive assumptions about how base rates should be used. The restrictive assumptions stem from a misuse of Bayes' rule that ignores specific aspects of how the proportions arose. We develop a model of rational behavior that generalizes signal detection theory to reflect the environment subjects routinely face and we reexamine the relevant experimental literature. Variation observed in subjects' responses to base rate information is explained by the present rational model more fully than by extant models.

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.

Reliability of reports of violent victimization and posttraumatic stress disorder among men and women with serious mental illness.
Although violent victimization is highly prevalent among men and women with serious mental illness (SMI; e.g., schizophrenia, bipolar disorder), future research in this area may be impeded by controversy concerning the ability of individuals with SMI to report traumatic events reliably. This article presents the results of a study exploring the temporal consistency of reports of childhood sexual abuse, adult sexual abuse, and adult physical abuse, as well as current symptoms of posttraumatic stress disorder (PTSD) among 50 people with SMI. Results show that trauma history and PTSD assessments can, for the most part, yield reliable information essential to further research in this area. The study also demonstrates the importance of using a variety of statistical methods to assess the reliability of self-reports of trauma history.

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.

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.

Burden and well-being of caregivers for the severely mentally ill: the role of coping style and social support.
Caregivers of persons with severe mental illness often experience a significant burden in coping with patients' symptoms. Several factors have been hypothesized to mediate the impact of caring for a mentally ill relative, including cognitive appraisal, coping strategies, and social support. The present study examined the relationships between these factors, and subjective burden and well-being in caregivers of persons with a severe mental illness. Higher levels of subjective burden were related to (1) greater perceived frequency of positive and negative symptom behaviors, (2) a tendency to use problem-focused oriented coping for dealing with negative symptom behaviors, and (3) a tendency not to use problem-solving oriented coping for dealing with positive symptom behaviors. Well-being was also related to lower perceived frequency of positive symptom behaviors and social support, but not to coping style. The implications of the findings for interventions designed to reduce caregiver subjective burden are discussed.

Training schizophrenic patients to manage their symptoms: predictors of treatment response to the German version of the Symptom Management Module.
This study examined whether patient demographic and clinical characteristics were predictors of differential treatment response in a sample of 57 schizophrenic patients who received the German version of the Symptom Management Module. Psychopathology, global functioning and knowledge about schizophrenia were assessed as dependent variables. Overall, patients improved over the treatment period on most dimensions of psychopathology as well as knowledge about psychosis. There was little evidence of differential treatment response as a function of either sociodemographic or clinical variables. However, gender was related to changes in psychopathology from pre- to posttreatment, with females improving less than males. Possible implications of these findings were discussed.

Organizational guidelines for dual disorders programs.
Dual disorders--combined severe mental disorders and substance use disorders--were barely recognized two decades ago. As a result of the high prevalence and serious consequences of these disorders, they have received considerable attention over the last two decades. Knowledge has accumulated about dual disorders and their treatment, and treatment providers may now consider numerous options for clinical interventions and program designs. In this article, we offer guidelines concerning these options. We review the current knowledge about dual disorders and the results of recent research on the assessment and treatment of these disorders. We present treatment principles, recommendations on the components and organization of dual disorders programs, and suggestions for dealing with clinical issues that remain controversial. We conclude with comments on the demands of the managed care environment and the heightened importance of continued research in this area.

Empirically supported couple and family interventions for marital distress and adult mental health problems.
This article evaluates the efficacy, effectiveness, and clinical significance of empirically supported couple and family interventions for treating marital distress and individual adult disorders, including anxiety disorders, depression, sexual dysfunctions, alcoholism and problem drinking, and schizophrenia. In addition to consideration of different theoretical approaches to treating these disorders, different ways of including a partner or family in treatment are highlighted: (a) partner-family-assisted interventions, (b) disorder-specific partner-family interventions, and (c) more general couple-family therapy. Findings across diagnostic groups and issues involved in applying efficacy criteria to these populations are discussed.

Trauma and posttraumatic stress disorder in severe mental illness.
This research assessed the lifetime prevalence of traumatic events and current posttraumatic stress disorder (PTSD) in 275 patients with severe mental illness (e.g., schizophrenia and bipolar disorder) receiving public mental health services in Concord and Manchester, New Hampshire, and Baltimore, Maryland. Lifetime exposure to traumatic events was high, with 98% of the sample reporting exposure to at least 1 traumatic event. The rate of PTSD in our sample was 43%, but only 3 of 119 patients with PTSD (2%) had this diagnosis in their charts. PTSD was predicted most strongly by the number of different types of trauma, followed by childhood sexual abuse. The findings suggest that PTSD is a common comorbid disorder in severe mental illness that is frequently overlooked in mental health settings.

Models of community care for severe mental illness: a review of research on case management.
We describe different models of community care for persons with severe mental illness and review the research literature on case management, including the results of 75 studies. Most research has been conducted on the assertive community treatment (ACT) or intensive case management (ICM) models. Controlled research on ACT and ICM indicates that these models reduce time in the hospital and improve housing stability, especially among patients who are high service users. ACT and ICM appear to have moderate effects on improving symptomatology and quality of life. Most studies suggest little effect of ACT and ICM on social functioning, arrests and time spent in jail, or vocational functioning. Studies on reducing or withdrawing ACT or ICM services suggest some deterioration in gains. Research on other models of community care is inconclusive. We discuss the implications of the findings in terms of the need for specialization of ACT or ICM teams to address social and vocational functioning and substance abuse. We suggest directions for future research on models of community care, including evaluating implementation fidelity, exploring patient predictors of improvement, and evaluating the role of the helping alliance in mediating outcome.

Anhedonia, positive and negative affect, and social functioning in schizophrenia.
This study examines the relationship between anhedonia and the trait dimensions of positive affect (PA) and negative affect (NA) in schizophrenia. The relationship between poor social functioning in schizophrenia and these individual differences in affectivity is also examined. Schizophrenia outpatients (n = 37) and normal controls (n = 15) were assessed at a baseline evaluation and again approximately 90 days later. Consistent with the hypothesized decrease in hedonic capacity in schizophrenia, patients reported significantly greater physical and social anhedonia and less PA than controls. However, the schizophrenia group also reported significantly greater NA and social anxiety than did controls. In support of the dispositional view of these individual differences in affectivity, trait measures demonstrated test-retest reliability, and group differences between the schizophrenia group and controls were stable over the 90-day followup period. Within the schizophrenia group, physical and social anhedonia were comparably negatively correlated with trait PA; however, social but not physical anhedonia was significantly positively correlated with NA and social anxiety. Poor social functioning in the schizophrenia group was associated with greater physical and social anhedonia and greater NA and social anxiety. Alternatively, greater trait PA was related to better social functioning. These findings indicate that schizophrenia is characterized by both low PA and elevated NA and that these affective characteristics are a stable feature of the illness. The results also suggest important links between affect and social functioning in schizophrenia.

Review of integrated mental health and substance abuse treatment for patients with dual disorders.
Patients with severe mental disorders such as schizophrenia and co-occurring substance use disorders traditionally received treatments for their two disorders from two different sets of clinicians in parallel treatment systems. Dissatisfaction with this clinical tradition led to the development of integrated treatment models in which the same clinicians or teams of clinicians provide substance abuse treatment and mental health treatment in a coordinated fashion. We reviewed 36 research studies on the effectiveness of integrated treatment for dually diagnosed patients. Studies of adding dual-disorders groups to traditional services, studies of intensive integrated treatments in controlled settings, and studies of demonstration projects have thus far yielded disappointing results. On the other hand, 10 recent studies of comprehensive, integrated outpatient treatment programs provide encouraging evidence of the programs' potential to engage dually diagnosed patients in services and to help them reduce substance abuse and attain remission. Outcomes related to hospital use, psychiatric symptoms, and other domains are less consistent. Several program features appear to be associated with effectiveness: assertive outreach, case management, and a longitudinal, stage-wise, motivational approach to substance abuse treatment. Given the magnitude and severity of the problem of dual disorders, more controlled research on integrated treatment is needed.

Dartmouth Assessment of Lifestyle Instrument (DALI): a substance use disorder screen for people with severe mental illness.
OBJECTIVE: Despite high rates of co-occurring substance use disorder in people with severe mental illness, substance use disorder is often undetected in acute-care psychiatric settings. Because underdetection is related to the failure of traditional screening instruments with this population, the authors developed a new screen for detection of substance use disorder in people with severe mental illness. METHOD: On the basis of criterion ("gold standard") diagnoses of substance use disorder for 247 patients admitted to a state hospital, the authors used logistic regression to select the best items from 10 current screening instruments and constructed a new instrument. They then tested the validity of the new instrument, compared with other screens, on an independent group of 73 admitted patients. RESULTS: The new screening instrument, the Dartmouth Assessment of Lifestyle Instrument (DALI), is brief, is easy to use, and exhibits high classification accuracy for both alcohol and drug (cannabis and cocaine) use disorders. Receiver operating characteristic curves showed that the DALI functioned significantly better than traditional instruments for both alcohol and drug use disorders. CONCLUSIONS: Initial findings suggest the DALI may be useful for detecting substance use disorder in acutely ill psychiatric patients. Further research is needed to validate the DALI in other settings and with other groups of psychiatric patients.

A comparative study of elderly patients with schizophrenia and bipolar disorder in nursing homes and the community.
This study compared the functioning of 188 elderly schizophrenic and bipolar disorder patients living in nursing homes and the community. Residential status and diagnostic groups were compared on measures of symptomatology, cognitive impairment, functional impairment, and behavior problems. In general, the diagnostic groups differed in symptoms, while most differences in living setting were related to cognition, functioning, and behavior. Nursing home status was significantly associated with more severe overall symptom ratings, worse cognitive impairment, greater functional impairment, more aggressive behaviors, and marital status of having never married. Self-care skills, community living skills, and marital status were most uniquely predictive of nursing home residence. However, cognitive deficits were strongly predictive of both self-care and community living skills, explaining approximately half of the variance in these variables. The implications of these findings for the treatment of elderly patients with schizophrenia and other severe mental illnesses are discussed.

Positive and negative symptom behaviors and caregiver burden in the relatives of persons with schizophrenia.
OBJECTIVE: The relationships of perceived severity and responsibility attribution for positive and negative symptom behaviors to caregiver burden were investigated. Two types of burden were studied: objective burden (i.e., negative consequences such as physical problems, financial difficulties, and household tension), and subjective burden (i.e., emotional distress about disturbing behaviors). METHOD: Self-report measures were completed by 70 primary caregivers of persons with schizophrenia. RESULTS: Subjective burden was related to both the severity of positive and negative symptom behaviors, whereas objective burden was related only to the severity of negative symptom behaviors. Responsibility attribution for negative symptom behaviors was related only to objective burden. Caregivers who perceived patients as being less responsible for their negative symptom behaviors reported higher levels of objective burden. The relationship between responsibility attribution for negative symptom behaviors and objective burden remained significant, even after controlling for the severity of negative symptom behaviors. Caregivers' perceptions of patients' responsibility for positive symptom behaviors were not related to objective burden. CONCLUSIONS: As expected, perceived severity of negative symptom behaviors was related to objective caregiver burden, whereas severity of positive symptom behaviors was not. These findings suggest that negative symptoms may have a greater impact on role functioning that positive symptoms, leading to greater burden. However, contrary to expectations, less responsibility attribution for negative symptom behaviors was related to higher levels of objective caregiver burden. Caregivers who perceive patients as incapable of altering their negative symptom behaviors and meeting certain role obligations may assume extra responsibilities, leading to higher levels of objective burden. The results indicate that there may be disadvantages for caregivers associated with assuming that patients have no control over their negative symptom behaviors.
