This monograph details the growing body of research showing the connection between child maltreatment and juvenile delinquency. In 2000, nearly 879,000 children were victims of child abuse and neglect. Although juvenile crime has declined recently, the level of crime committed by youth remains high. This monograph describes an array of program, practice, and system efforts for developing responses to juvenile crime and coordinating the child welfare and juvenile justice systems. These efforts can be the foundation for practitioners and policymakers in reducing the risk of maltreatment and sustaining declines in juvenile delinquency nationwide. (Author)
