Housing interventions for dual diagnosis patients: a scoping review (Data collection)

We conducted a scoping review to map the published literature on housing interventions for individuals with co-occurring severe mental illness and substance use disorders. The review was conducted in accordance with the PRISMA Extension for Scoping Reviews (PRISMA-ScR). The objective of the search was to identify the range of housing and residential intervention models that have been evaluated among individuals with dual diagnosis and to characterize the interventions, study designs, and reported outcomes. Data was mined on March 2, 2024 using 3 different databases: Pubmed, Embase and PsychInfo. The search was conducted using a search string for: (Housing OR Residential) AND (Dual Diagnosis OR Co-occurring illness) AND (Treatment OR Intervention). The data was refined to include only original research articles. The study was registered in OSF. After peer review, the literature search was rerun using the same criteria on June 5, 2026 to identify studies published since the original search date.
