The present study explored the effects of child sexual abuse (CSA) on the adaptation of male juveniles who subsequently sexually offended (JSOs; n = 178; age, M = 16.05 years, SD = 0.27, range = 12-22). It examined multiple levels of interpersonal closeness between the perpetrators of sexual abuse and their JSO victims. JSOs who were sexually abused by older children or adults who cohabitated with them for at least 3 months reported higher levels of emotional dysregulation, callousness/manipulativeness, and sexualization than did both JSOs who were sexually abused by someone they had never lived with and JSOs who reported no experiences of sexual abuse. Implications of these findings are discussed.
