This review addresses research regarding associations between child maltreatment and youth violence perpetration. The authors explore current findings on the direct effects of child maltreatment on later youth violence and possible gender and ethnic differences. They examine differences in the prediction of adolescent violence as a function of duration and timing of maltreatment. Results provide compelling evidence linking child maltreatment and later youth violence, although some research is inconclusive once demographics and other competing predictors are considered. Overall, physical abuse is perhaps the most consistent predictor of youth violence, patterned by an increased risk for children exposed to severe, compounded maltreatment. However, findings indicate that lesser severe forms of abuse can increase the risk of later violence for some youth. Limitations of current research include relatively few prospective, studies on the abuse-violence link; a general lack of specificity in definitions of key variables; and inconsistency in data analysis methods.
