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.

新加坡性犯罪者再犯风险评估工具的探索性研究

在过去的 40 年里，风险评估工具对性犯罪者的预测有效性有了巨大的提高，但进展仅限于西方的犯罪者群体。本研究的目的是检验 Static-99R、Stable-2007、Sexual Violence Risk-20、Version 2 (SVR-20 v2)、Psychpathy Checklist-Revised (PCL-R) 和 Level of Service/案例管理清单 (LS/CMI) 用于预测在新加坡因性犯罪而被定罪的人的再犯。使用 134 名此类人员的回顾性数据对各种仪器进行编码。接收器操作特征分析显示，结合 Static-99R/Stable-2007 新标准化风险评级、SVR-20 v2 总分和风险评级、PCL-R 总分、以及 LS/CMI 总分和风险评级预测性再犯。所有上述工具的总分和风险评级（如果适用）都预测了任何累犯。然而，该样本的风险概况与规范的西方样本有显着差异。
