Within the past twenty years, the incidence of child sexual abuse jumped from just one in a million to one in four or five children (Hastings, 2000). In this time, the conception of female children as victims of inappropriate male sexual behavior has dominated the research, and thus our understanding of child sexual abuse. However, recent research consistently reveals that females account for about one in four offenders (Pearson, 1997), and emerging research often challenges the current construct of perpetrators (Fitzroy, 1997), and highlights the special concerns of their victims. Thus, increased attention to female-female sexual abuse is important not only to provide intervention and support for perpetrators and survivors, but also to increase our overall understanding of human sexuality and child sexual abuse.
