This study examines predictors of successful completion in a residential Substance Abuse Treatment Facility (SATF) for men on probation and evaluates the impact of treatment completion on probation outcomes. Using secondary data from a multi-county probation department ( n = 243), analyses examined the associations among demographic factors, probation characteristics, and program outcomes. Findings show that older age and obtaining a GED/high school diploma increased the odds of SATF completion, while being on probation for a felony offense reduced it. Successful program completion significantly decreased the odds of probation revocation (by 88%), rearrest (by 64%), and reincarceration (by 70%). Hispanic participants and those with longer probation terms were more likely to be revoked, highlighting systemic disparities and the risk posed by lengthy supervision. Prior criminal history was a strong predictor of reincarceration, but prior substance offenses were associated with reduced reincarceration risk, suggesting the potential effect of treatment engagement. Results emphasize the importance of individualized, continuum-of-care models of treatment. Implications for policy and practice are provided.
