The Static-99R has been recommended for use as a first global screen for sorting out sex-convicted persons who are in need of further risk assessment. This study investigated the Static-99R’s predictive validity based on a nonselected Norwegian sample (n = 858) of persons released from prison after having served a sex crime sentence. After a mean observation period of 2,183 days, 3.4% (n = 29) had recidivated to a new sex offense. A higher number of recidivists were found among those with higher Static-99R total scores. The predictive contribution from each of the ten Static-99R risk items was investigated using standard logistic regression, proportional hazard regression, and random forest classification algorithm. The overall results indicate that the Static-99R is relevant as a risk screen in a Norwegian context, providing similar results concerning predictive accuracy as previous studies.

Static-99R 已被推荐用作第一个全球筛选器，用于筛选需要进一步风险评估的性犯罪者。本研究基于未选择的挪威样本 ( n = 858)调查了 Static-99R 的预测有效性，这些样本是在性犯罪服刑后获释的人。经过 2,183 天的平均观察期后，3.4% ( n= 29) 再次犯下新的性犯罪。在静态 99R 总分较高的人中发现了更多的惯犯。使用标准逻辑回归、比例风险回归和随机森林分类算法研究了 10 个 Static-99R 风险项目中每一个的预测贡献。总体结果表明，Static-99R 与挪威语境中的风险筛查相关，在预测准确性方面提供与先前研究相似的结果。
