Poly-victimization among girls in the justice system: trajectories of risk and associations to juvenile offending.

Life History Calendars and the Juvenile Victimization Questionnaire were used to collect data from 100 delinquent girls to (a) examine range and co-occurrence of different types of violence over the life span, (b) examine independent and cumulative trajectories of risk for varied types of victimization, and (c) examine the relationship of victimization to girls' offending. Risk trajectories demonstrate critical risk periods for different forms of violence exposure. Cox regression was used to examine the predictive value of different forms of violence exposure for the onset of delinquent and criminal behavior. Findings illuminate the need for programs addressing substance use and alternative coping mechanisms.
