The impact of trauma on girls involved in the juvenile justice system is examined. Sections of this fact sheet cover: why there are increasing numbers of girls in the juvenile justice system; prevalence of trauma-exposure among justice-involved girls; prevalence of PTSD (posttraumatic stress disorder) among justice-involved girls; potential consequences of trauma for girls; impact of the juvenile justice system on traumatized girls; and gender-responsive programming. This review suggests that trauma-informed and gender-responsive programming and intervention models are needed in order to address girls’ needs and to prevent retraumatization of girls in the juvenile justice system. Experiences of trauma, maltreatment, and victimization play a role in placing many girls on the pathway toward delinquency. Further, girls who participate in delinquent activities are at risk for retraumatization and the additional long-term consequences associated with polyvictimization (p. 8).
