Researchers generally agree that treatment reduces the likelihood of sexual offender recidivism. However, studies show attrition rates of up to 85% in some treatment programs for sex offenders. Because many risk factors for recidivism and treatment attrition are the same, the present study used gold-standard risk assessments to predict which sex offenders would not complete a community treatment program. The Static-99r, Stable-2007, and URICA assessed static risk factors, dynamic needs, and responsivity to treatment for 289 sex offenders. Pre-treatment scores from the sex offenders in the sample indicated that these assessment instruments could predict treatment attrition for sex offenders in community treatment (AUC = .928). The Stable-2007 was the best predictor of treatment attrition. Implications of the results and directions for future research are also discussed.
