Male victims of sexual abuse may be less likely to report abuse than female victims due to cultural bias and lack of physical trauma. Studies indicate that specifically victimized males are at risk of becoming offenders. The impact of sexual abuse on male victims is considered along with a review of the literature on therapy outcome. A study of 27 juvenile sex offenders with a history of prior victimization is presented in detail. It is recommended that all adolescent sex offenders receive treatment since those who will continue to commit sex crimes cannot be predicted. A cognitive behavioral treatment model is described which has been used successfully to teach adolescents the behavior that is incompatible with reoffending. 3 tables, 27 references.
