The goal of this study was to identify predictors of successful substance abuse treatment in an out-patient clinic for individuals being monitored under community corrections supervision. Of the 615 participants, 117 (19%) successfully completed treatment. The results of a multivariate logistic regression analysis indicated that successful treatment was associated with several baseline characteristics including: older age, White race, having greater than a high school education, lower level of care, meeting criteria for an anxiety disorder, reporting suicidal ideation, and not having a history of opioid use. The value of self-report of problems and its influence on treatment in the culture of the criminal justice population is discussed in this article. © 2014 Informa Healthcare USA, Inc.
