Abstract

The predictive validity of risk assessment instruments for persons who have committed sexual offenses has improved tremendously in the last four decades, but the progress has been limited to Western offender populations. The aim of this study was to examine the predictive validity of Static-99R, Stable-2007, Sexual Violence Risk-20, Version 2 (SVR-20 v2), Psychopathy Checklist-Revised (PCL-R), and Level of Service/Case Management Inventory (LS/CMI) in predicting recidivism of persons convicted on sexual offenses in Singapore. Retrospective data of 134 such persons were used to code the various instruments. Receiver operating characteristic analyses revealed that combined Static-99R/Stable-2007 new standardized risk ratings, SVR-20 v2 total scores and risk ratings, PCL-R total scores, as well as LS/CMI total scores and risk ratings predicted sexual recidivism. All the aforementioned instruments' total scores and risk ratings (if applicable) predicted any recidivism. However, risk profiles of this sample differed significantly from the normative Western samples.
