Abstract
This is the first study comparing community-based and hospitalized homeless dually diagnosed men to assess correlates of psychiatric hospitalization. A retrospective review was carried out comparing housing, substance abuse, and psychiatric histories of three cohorts: 53 previously homeless men interviewed while hospitalized for dual psychiatric and addictive disorders, 87 homeless men previously hospitalized, and 500 homeless men never hospitalized. Individuals reporting current or past psychiatric hospitalization more often reported a history of illicit drug use. The findings suggest that history of illicit drug use by homeless men is associated with a higher risk of psychiatric hospitalization.
