Abstract:
The current research examines the predictive validity of the Static-99 and the SORAG in predicting sexual and violent recidivism among a sample of 258 treated high-risk sexual offenders. While the SORAG was found to have moderate predictive accuracy for both sexual and violent recidivism over a 5-year follow-up period, the Static-99 was found to only predict sexual recidivism. As well, the actual recidivism rates in the current sample were compared to the published risk percentages for each of the instruments. For both the Static-99 and the SORAG the current sample re-offended at a lower rate than expected. Possible explanations for this finding are discussed.
