A 12-Month Follow-Up Evaluation of Integrated Treatment for Homeless Individuals With Co-Occurring Disorders

ABSTRACT

This study examined the effectiveness of the Comprehensive, Continuous, Integrated System of Care (CCISC) model in addressing co-occurring mental health and substance use disorders. Clients were eligible for participation if they had co-occurring disorders and were homeless or at risk of homelessness. Forty-eight clients received a comprehensive array of services consistent with the CCISC model. Measures assessing housing, employment, mental health, and substance use were completed at baseline, 6-month, and 12-month follow-up. Results demonstrated significant improvements in housing, employment, mental health, and substance use at 12-month follow-up. These results underscore the effectiveness of implementing evidence-based care.
