Research has identified meaningful subtypes among the heterogeneous population of juveniles who sexually offended (JSO). However, studies that test the validity of risk assessment tools with JSO subtypes are limited. This study compared JSO who offended against a child victim (JSO-C) and JSO who offended against an adolescent/adult victim (JSO-A) with regard to rates of recidivism and the predictive validity of two risk assessment tools (Estimate of Risk of Adolescent Sexual Offense Recidivism [ERASOR] and Juvenile Sexual Offender Assessment Protocol-II [J-SOAP-II]). Data were analyzed from case files of 185 JSO-C and 297 JSO-A aged 12 to 18 years (M = 14.11, SD = 1.44) from a consecutive sample of JSO with contact sexual offenses. A total of 34 (7.1%) juveniles reoffended sexually, with no significant difference between the subtypes. The present results suggest that the ERASOR, particularly the structured professional judgment, and to a lesser degree the J-SOAP-II are better suited to predicting sexual recidivism in JSO-A than in JSO-C.

风险评估工具在性侵犯青少年中的有效性：受害者年龄很重要

研究已经在性冒犯 (JSO) 的异质青少年群体中确定了有意义的亚型。然而，用 JSO 子类型测试风险评估工具有效性的研究是有限的。本研究比较了冒犯儿童受害者的 JSO (JSO-C) 和冒犯青少年/成人受害者的 JSO (JSO-A) 的累犯率和两种风险评估工具的预测有效性（风险估计）青少年性犯罪累犯 [ERASOR] 和青少年性犯罪者评估协议-II [J-SOAP-II]）。对 185 名 JSO-C 和 297 名 12 至 18 岁的 JSO-A（M = 14.11，SD = 1.44）的案例档案的数据进行了分析，这些数据来自具有接触性犯罪的 JSO 连续样本。共有 34 名 (7.1%) 青少年再次性犯罪，亚型之间没有显着差异。
