Many forensic assessment measures are developed and validated under research conditions but applied in the field, where professionals or paraprofessionals have varied training, unknown fidelity to administration procedures, and contextual pressures related to their institutions or legal system. Yet few studies examine the generalizability of psychometric properties of these scales as actually applied in field settings. This study examined 4,433 individuals assessed by probation officers on the Static-99R or STABLE-2007 sexual recidivism risk scales in British Columbia, Canada. Sexual, violent, and any recidivism were examined. Static-99R and STABLE-2007 had moderate accuracy in discriminating recidivists from non-recidivists, and both scales added incrementally in predicting all three outcomes (with Static-99R demonstrating higher accuracy). Organizing the items into constructs, sexual criminality, general criminality, and youthful stranger aggression incrementally predicted all three outcomes. For violent and any recidivism, the incremental effect of sexual criminality was in the negative direction (i.e., high sexual criminality was associated with relatively lower rates of violent and any recidivism). Calibration analyses indicated that recidivism rates were lower than what would be predicted by the norms for the scales. The current study also presented a meta-analysis of 15 field validity studies of Static-99R and 4 field validity studies of STABLE-2007. Results of the current study and meta-analysis support the field application of Static-99R and STABLE-2007, while emphasizing the importance of training and proper implementation.

Static-99R 和 STABLE-2007 的现场有效性,4,433 名在不列颠哥伦比亚省因性犯罪服刑的男子:新发现和元分析。

许多法医评估措施是在研究条件下开发和验证的,但在现场应用,其中专业人员或辅助专业人员接受过不同的培训,对管理程序的忠诚度未知,以及与其机构或法律体系相关的背景压力。然而,很少有研究检查这些量表在实际应用中的心理测量特性的普遍性。这项研究调查了 4,433 名缓刑官员在加拿大不列颠哥伦比亚省使用 Static-99R 或 STABLE-2007 性再犯风险量表进行评估的个人。检查了性、暴力和任何累犯。Static-99R 和 STABLE-2007 在区分惯犯和非惯犯方面具有中等准确度,并且这两个量表在预测所有三种结果方面都逐渐增加(Static-99R 显示出更高的准确度)。将项目组织成结构、性犯罪、一般犯罪和年轻的陌生人攻击,逐渐预测了所有三种结果。对于暴力和任何累犯,性犯罪的增量影响是负面的(即,高性犯罪与相对较低的暴力和任何累犯率相关)。校准分析表明,再犯率低于量表规范所预测的。目前的研究还对 Static-99R 的 15 项现场有效性研究和 STABLE-2007 的 4 项现场有效性研究进行了荟萃分析。当前研究和荟萃分析的结果支持 Static-99R 和 STABLE-2007 的现场应用,同时强调了培训和正确实施的重要性。(PsycInfo 数据库记录 (c) 2021 APA,
