The comparative effectiveness of different models of permanent supportive housing on problematic substance use, depression, and anxiety symptoms over time.

OBJECTIVES To compare the effectiveness of different models of permanent supportive housing (PSH), housing configuration, and service provision model on substance use, depression, and anxiety symptoms among residents over time. METHODS Linear mixed model regression was used with 888 residents of PSH to investigate the relationship between supportive housing type, service model, and housing configuration and change in mental health and substance use at baseline, 6-, 12-, and 18-month follow-up. RESULTS There were few significant differences in problematic substance use, depression, or anxiety symptoms among those in different PSH types, different housing configuration models, or different service provision models. Similarly, there were no significant differences in PSH type, housing configuration, or service delivery model among those with severe mental illness (SMI), substance use disorder (SUD), or those with dual diagnoses. CONCLUSIONS There is little evidence that different models of PSH result in differences in mental health and substance use outcomes. Future research should consider the number of services clients receive and critical periods in PSH residency in improving mental health and substance use outcomes.
