Determinants of functioning and well-being among individuals with schizophrenia: an integrated model.

Outcomes for health conditions are typically the result of multiple factors; however, studies tend to focus on a narrow class of variables. Functioning and well-being outcomes for schizophrenia are diverse and have resisted simple explanation; however, prior research has not offered an integrated understanding of the relative contributions of enduring and episodic environmental factors, personal resources and psychiatric factors, and cognitive appraisal and coping, on functioning and well-being outcomes in schizophrenia. The present article sets out an integrated model of the determinants of functioning and well-being among individuals with schizophrenia. To examine evidence that bears on the model, literature on hypothesized relationships is reviewed to identify areas for which there is strong evidence and areas where more research is needed. The article suggests areas for further research, and directs researchers and practitioners toward areas of intervention that can enhance functioning and well-being for persons diagnosed with schizophrenia.

Negative and supportive social interactions and quality of life among persons diagnosed with severe mental illness.

This study examined the relative importance of negative and supportive social interactions in predicting different aspects of quality of life (QOL) in a sample of persons diagnosed with severe mental illness (n = 104). Controlling for other variables that might explain such a relationship, we found that negative social interactions were significantly related to lower QOL in three subjective domains, while supportive social interactions were related to higher QOL in four objective domains and one subjective domain. We found negative social interactions that are stigmatizing to be particularly important in predicting QOL; additional analyses suggested that perceived stigma partially mediated the relationship between negative social interactions and QOL. We discuss the implications of the present findings for the study of the link between social relationships and QOL among persons with mental illness.

Characteristics and service use patterns of nonelderly medicare beneficiaries with schizophrenia.

OBJECTIVE: The authors sought to describe the characteristics of nonelderly Medicare beneficiaries who have a diagnosis of schizophrenia and to assess the impact of Medicare financing on service quality by comparing service use among individuals who were enrolled only in Medicare and those who were enrolled in both Medicare and Medicaid. The authors hypothesized that persons who received only Medicare benefits would use proportionally fewer psychosocial services and less antipsychotic medication than individuals who were dually enrolled. METHODS: Data were drawn from the Medicare Current Beneficiary Survey (MCBS). The study sample consisted of 257 individuals younger than age 65 who were included in the 1995 MCBS sample and who had one inpatient or two outpatient claims for schizophrenia between 1992 and 1996. The variables examined were demographic characteristics, comorbid psychiatric and substance use disorders, activities of daily living, instrumental activities of daily living, self-reported use of prescribed antipsychotic medication, and claims for psychosocial services. A multivariate analysis was also conducted to predict the use of antipsychotic medication from demographic and health status variables. RESULTS: Dually enrolled beneficiaries were significantly more likely to be receiving antipsychotic medication than Medicare-only beneficiaries, even when the analysis controlled for demographic characteristics, health status, and comorbidity. No significant differences were found in the use of psychosocial services. CONCLUSIONS: The findings were consistent with the hypothesis that Medicare financing, which restricts access to many mental health services, is not conducive to good community care for persons with schizophrenia.

Consumer-run service participation, recovery of social functioning, and the mediating role of psychological factors.

OBJECTIVE: This study examined the relationship between participation in consumer-run services and recovery of social functioning among persons diagnosed as having serious mental illness. It also assessed the role of psychological factors in mediating this relationship. METHODS: Research questions investigated were whether involvement in consumer-run services is positively associated with recovery when premorbid and demographic factors are controlled for, whether psychological factors are positively associated with recovery irrespective of involvement in consumer-run services, and whether the relationship between involvement in consumer-run services and recovery is mediated by the psychological factors. The factors examined were self-efficacy, hopefulness, and active coping strategies. Sixty participants with a past or present diagnosis of schizophrenia, schizoaffective disorder, or bipolar disorder and at least one past psychiatric hospitalization were recruited from a community mental health center and two consumer-run programs. Data were collected on hopefulness, self-efficacy, coping strategies, social functioning, and premorbid and demographic characteristics. RESULTS: Findings indicated that participants involved in consumer-run services had better social functioning than those involved only in traditional mental health services, that psychological variables were significantly associated with social functioning, and that the relationship between involvement in consumer-run services and social functioning was partly mediated by the use of more problem-centered coping strategies. Premorbid and demographic factors did not account for the relationship between psychosocial variables and social functioning, although education was a significant predictor of social functioning. CONCLUSIONS: The findings support the view that psychosocial factors may play a role in facilitating good community adjustment for individuals diagnosed as having serious mental illness.

Methodological problems encountered in research with psychiatric inpatients: a case example.

In this article, problems associated with several methods commonly employed in research with psychiatric inpatients are discussed and the implications that these problems have for the validity of research with this population are explored, using an investigation of the relationship between moral reasoning and aggression among psychiatric inpatients as a case example. Specific issues examined include the adequacy of hospital records for diagnosing patients, the difficulty of determining when it is appropriate to approach recently admitted patients for research, and problems in the measurement of behavioral and psychological variables such as aggression and moral reasoning. Suggestions and recommendations for addressing these issues in future research are offered.
