This study aimed to help determine whether adolescent female sex offenders constitute a unique group in terms of exposure to psychosocial risk factors that literature suggests influence the development of sexual offending behavior. Using archival data from youth referred to the juvenile justice system for violent “hands-on” felonies, a group of adolescent female sex offenders (N = 145) was compared with equal-sized groups of adolescent female delinquents, adolescent male sex offenders, and adolescent male delinquents. As expected, significantly more sex offending girls than boys had experienced sexual abuse and depression/anxiety and had been diagnosed with a mental disorder. Additionally, when compared with delinquent girls, sex offending girls had experienced more sexual abuse and trauma; however, there were no differences between these groups of girls in terms of depression/anxiety and suicidality. Finally, although a substantial proportion of both sex offending and delinquent girls had experienced poly-victimization, nearly one third had not experienced any trauma or victimization. The findings of this study suggest that further empirical research is needed to better understand the ways in which sex offending girls resemble other delinquent youth.
