Purpose

Risk assessment studies involving recidivism in sex offenders with intellectual disabilities (SOIDs) continue to be scarce, limited and producing mixed results. This study aims (to test the ability ...) to test the ability of one such instrument (the Static-99R) to predict intramural sexual and violent incidents involving members of this group.

Design/methodology/approach

The Static-99R was prospectively scored for 38 SOIDs. Occurrences of any violent or sexual incident and/or illegal sexual behaviour were recorded during a minimum period of six months. Predictive accuracy was analysed using several performance indicators.

Findings

The Static-99R significantly predicted sexual incidents (area under the curve = 0.70) but failed to predict violent and illegal sexual incidents. Regarding illegal sexual incidents, the instrument was better at detecting low-risk individuals than high-risk offenders.

Originality/value

Risk assessment studies, both in offenders with and without an intellectual disability (ID), rarely use multiple accuracy estimates. The current study used both discrimination and calibration indicators to evaluate the ability of the Static-99R to detect low- and high-risk offenders.

Static-99R 在智障性犯罪者中的信度和效度

目的

涉及智障性犯罪者 (SOID) 再犯的风险评估研究仍然稀缺、有限且产生的结果好坏参半。本研究旨在（测试能力……）测试一种此类仪器（Static-99R）预测涉及该群体成员的校内性和暴力事件的能力。

设计/方法/方法

Static-99R 对 38 个 SOID 进行了前瞻性评分。在至少六个月的时间内记录任何暴力或性事件和/或非法性行为的发生。使用几个性能指标分析预测准确性。

发现

Static-99R 显着预测性事件（曲线下面积 = 0.70），但未能预测暴力和非法性事件。关于非法性事件，该工具在检测低风险个人方面优于高风险犯罪者。

原创性/价值

风险评估研究，无论是在有还是没有智力障碍 (ID) 的罪犯中，都很少使用多重准确度估计。目前的研究使用辨别和校准指标来评估 Static-99R 检测低风险和高风险罪犯的能力。
