This evaluation of a supportive housing reentry pilot project, “Returning Home-Ohio”, yielded positive outcomes for program participants. The pilot project, developed jointly by the Ohio Department of Rehabilitation and Correction and the Corporation for Supportive Housing, was designed for disabled prisoners returning from state prison to five Ohio cities. A process, impact, and cost evaluation employing a quasi-experimental design with multiple data sources found that RHO participants were significantly less likely to be rearrested or reincarcerated within one year of release and significantly more likely to be delivered substance abuse and mental health services, relative to a comparison group.
