Multidimensional item response theory (MIRT) was used to study the construct validity of the Static-2002R, an actuarial scale for the assessment of reoffending among adult men who sexually offended. Using a sample of 2,569 individuals with a history of sexual crime, exploratory factor analysis (EFA) extracted three factors: Persistence/Paraphilia, General Criminality, and Youthful Stranger Aggression. MIRT confirmed the factor structure identified in the EFA model and provided item-level data on discrimination and difficulty. All Static-2002R items showed moderate to very high discrimination and covered a wide range of risk levels (i.e., difficulty). MIRT analyses attested to the construct validity of the scale, as no items were identified as problematic and the resulting factor structure was consistent with that of earlier studies. Considering the stability of results pertaining to the factor structure of the Static-2002R and the advantages of dimensional scoring, we recommend the integration of dimensional scores in the scale.

多维项目反应理论 (MIRT) 用于研究 Static-2002R 的结构有效性，Static-2002R 是一种精算量表，用于评估性侵犯成年男性的再犯罪情况。使用 2,569 名有性犯罪史的个人作为样本，探索性因素分析 (EFA) 提取了三个因素：持久性/性倒错、一般犯罪和年轻的陌生人攻击性。MIRT 确认了 EFA 模型中确定的因素结构，并提供了关于歧视和难度的项目级数据。所有 Static-2002R 项目都表现出中等到非常高的歧视，涵盖了广泛的风险水平（即难度）。MIRT 分析证明了该量表的结构有效性，因为没有项目被确定为有问题，并且由此产生的因素结构与早期研究一致。
