Peer recovery services for persons returning from prison: Pilot randomized clinical trial investigation of SUPPORT

Previously incarcerated persons with substance use disorder (SUD) need recovery supports, given the overrepresentation of this population in prison and community supervision. Peer support programs have the potential to fill gaps in postrelease support for persons with SUD. To assess the effectiveness of peer support approaches, this pilot study randomized access to peer recovery coaches within a well-established community reentry program. We examined several proximal outcomes to determine potential mechanisms of action, along with several exploratory outcomes. While attrition due to re-incarceration, death, and program disengagement was high, our findings suggest that those who received peer recovery coach support in the reentry program had recovery-based improvements, including improved self-reported mental and physical health and reductions in substance use behaviors. The treatment group also saw improvements in measures of treatment motivation and self-efficacy. Both groups saw similar positive trends in some outcomes, likely due to the relative success of the well-established reentry program regardless of the inclusion of peer support coaches. This study contributes lessons learned and potential mechanisms of action to limited research on the effectiveness of peer recovery supports for reentry populations with SUD.
