This meta-analysis examined whether theoretically and clinically relevant differences exist between male adolescents who have sexually offended against intrafamilial victims (AIV) and male adolescents who have sexually offended against extrafamilial victims (AEV). A total of 26 independent samples (8 published and 18 unpublished) that compared a total of 2169 AIV and 2852 AEV were analyzed. The results of this meta-analysis indicate that categorizing male adolescents who commit sexual offenses based on their relationship to victims is a meaningful distinction. We found that AIV presented with greater atypical sexual interests, increased sexual regulation issues, more severe family dysfunction, more extensive childhood maltreatment histories, and greater internalizing psychopathology than AEV. Conversely, AEV presented with more indicators of antisociality than AIV, suggesting that extrafamilial sexual offending might fit better with a generalist explanation of adolescent sexual offending. Findings highlight the value of assessing family dysfunction and maltreatment history, sexual development and regulation, and general delinquency factors to better understand adolescents who have committed a sexual offense.

这项荟萃分析检查了对家庭内受害者 (AIV) 进行性侵犯的男性青少年与对家庭外受害者 (AEV) 进行性侵犯的男性青少年之间是否存在理论上和临床相关的差异。总共分析了 26 个独立样本（8 个已发表和 18 个未发表），对总共 2169 个 AIV 和 2852 个 AEV 进行了比较。这项荟萃分析的结果表明，根据与受害者的关系对实施性犯罪的男性青少年进行分类是一个有意义的区别。我们发现，与 AEV 相比，AIV 表现出更大的非典型性兴趣、更多的性调节问题、更严重的家庭功能障碍、更广泛的儿童期虐待史以及更大的内化精神病理学。反过来，AEV 呈现出比 AIV 更多的反社会指标，这表明家庭外性犯罪可能更适合对青少年性犯罪的通才解释。调查结果强调了评估家庭功能障碍和虐待史、性发育和调节以及一般犯罪因素的价值，以更好地了解犯下性犯罪的青少年。
