This study examined the patterns and correlates of group and organizational involvement among persons with psychiatric disabilities using a cross-sectional, probability sample of 252 residents in supported independent housing (SIH). Groups and organizations were classified according to whether or not they have a behavioral health focus. Demographic, clinical, and service use characteristics were examined as potential predictors of membership using Poisson regression models. Findings indicated that 60% of the sample was involved in some kind of behavioral or nonbehavioral health organization. Similar to the findings from the general population, higher rates of membership were found among older persons, Blacks, those with more years of education, and those with higher incomes. Other correlates specific to the SIH sample included prior homelessness, perceived discrimination, substance abuse history, psychiatric symptoms, psychiatric diagnosis, and contact with service providers. Implications of study findings for developing intervention strategies to enhance organizational membership and for future research are discussed. [ABSTRACT FROM AUTHOR]

This study examined the long-term effectiveness of the ACCESS (Access to Community Care and Effective Services and Supports) project on service utilization and continuity of care among homeless persons with serious mental illness. A 3-year longitudinal analysis, using Medicaid claims data, tracked behavioral health service utilization among 146 Medicaid-eligible participants in the Pennsylvania ACCESS program. Utilization patterns of inpatient, outpatient, and emergency department services for psychiatric and substance abuse treatment were examined during the year prior to, during, and one year after the implementation of the ACCESS project. Use of psychiatric ambulatory care significantly increased among intervention participants and remained greater following ACCESS intervention. Better continuity of care following hospitalization was achieved during and after the intervention. The number of days spent hospitalized significantly decreased during the intervention. These results suggest that the ACCESS intervention was effective in linking hard-to-reach homeless persons with serious mental illness to the community mental health service system, and that this effect was maintained after termination of the intervention.
