The phenomenon of juvenile female sexual offending was explored through the study of 67 youths who had been referred for either community-based or residential treatment following a documented history of sexual perpetration. These youths were compared to a group of 70 juvenile male sexual offenders across three parameters: developmental and psychiatric characteristics, history of maltreatment, and sexual perpetration characteristics. Relative to the juvenile males, the histories of the studied females reflected even more extensive and pervasive childhood maltreatment, with many of the youths exposed to the modeling of interpersonal aggression by females as well as males. The majority of these juvenile female sexual offenders demonstrated repetitive patterns of sexual offending with multiple victims, suggesting psychosexual disturbances equivalent in severity to the comparison group of males. The authors discuss typological impressions of this clinical population and their special treatment needs.
