Peer Support After Prison Cut Reconvictions — But a Side Effect Complicates the Picture

In a Georgia study of 150 people on probation or parole, those who received forensic peer support were reconvicted at a lower rate than matched peers (60.0% vs. 81.3%), though they also tested positive for drugs far more often.

Forensic peer support programs pair people leaving jail or prison with a trained mentor who has their own history of justice involvement, aiming to ease the notoriously difficult transition back into the community. This study evaluated whether the approach actually changes criminal-justice and behavioral-health outcomes. Researchers used propensity score matching — a statistical technique that pairs similar individuals who did and didn't receive a service, to approximate a controlled comparison — on 150 people involved in Georgia's probation and parole system, balancing the groups on demographic, criminal-legal, and behavioral-health characteristics. People who received forensic peer support were reconvicted less often than those who didn't (60.0% versus 81.3%), a substantial difference. But the picture wasn't uniformly positive: peer support recipients also had markedly more positive drug screens than nonrecipients, and there were no statistically significant differences in reincarceration or probation/parole revocation between the two groups. The authors describe the overall results as "mixed support" for forensic peer support, and note that programs may need to pair mentorship with more targeted substance-use treatment. A key limitation is the modest sample size (150 people) and the use of matching rather than random assignment, so it's possible unmeasured differences between groups — not the program itself — explain some of the results.
