The study compared the predictive accuracy of three sex offender risk-assessment measures: the RRASOR (Hanson, 1997), Thornton's SACJ-Min (Grubin, 1998), and a new scale, Static-99, created by combining the items from the RRASOR and SACJ-Min. Predictive accuracy was tested using four diverse datasets drawn from Canada and the United Kingdom (total n = 1301). The RRASOR and the SACJ-Min showed roughly equivalent predictive accuracy, and the combination of the two scales was more accurate than either original scale. Static-99 showed moderate predictive accuracy for both sexual recidivism (r = 0.33, ROC area = 0.71) and violent (including sexual) recidivism (r = 0.32, ROC area = 0.69). The variation in the predictive accuracy of Static-99 across the four samples was no more than would be expected by chance.
RRASOR（汉森，1997年）、桑顿的SACJ-Min（格鲁宾，1998年），以及一个新量表Static-99，它是通过合并RRASOR和SACJ-Min的项目创建的。使用从加拿大和英国抽取的四个不同数据集（总计n = 1301）对预测准确性进行了测试。RRASOR和SACJ-Min显示出大致相当的预测准确性，并且两个量表的组合比任何一个原始量表都更准确。Static-99对性再犯（r = 0.33，ROC面积 = 0.71）和暴力（包括性）再犯（r = 0.32，ROC面积 = 0.69）均显示出中等的预测准确性。Static-99在四个样本中的预测准确性差异不超过偶然预期。
