Abstract

The predictive validity of the Juvenile Sexual Offense Recidivism Risk Assessment Tool-II (JSORRAT-II) was evaluated using an exhaustive sample of 11- to 17-year-old male juveniles who offended sexually (JSOs) between 2000 and 2006 in Iowa (n = 529). The validity of the tool in predicting juvenile sexual recidivism was significant (area under the receiver operating characteristic curve [AUC] =.70, 99% confidence interval [CI] = [.60,.81], d = 0.70). Non-significant predictive validity coefficients were observed for the prediction of non-sexual forms of recidivism. Additional analyses were undertaken to test hypotheses about the tool's performance with various subsamples. The age of the JSO at the time of the index sexual offense and time at risk outside secure facility placements interacted significantly with JSORRAT-II scores to predict juvenile sexual recidivism. The implications of these findings for practice and research on the validation of risk assessment tools are discussed.
