Six papers examine issues in the development of aggression in young children and the progression of these behaviors to older children and adolescents. The first paper describes a developmental paradigm for aggressive conduct problems during the preschool years, followed by a discussion of prevention for developmental disparities in abused children. Other papers consider developmental changes in antisocial behavior, a social learning approach to working with children and adolescents to end the cycle of violence, intervention and prevention for bullying among school-children, and the facilitation of change in families with aggressive children and adolescents. The remaining eight chapters address violence in the adult life span. One chapter considers the clinical features and treatment of post-traumatic stress disorder, followed by a related chapter on the cognitive treatment of a crime-related post- traumatic stress disorder. Other papers focus on the use of the relapse prevention model with sex offenders, community risk management strategies with violent offenders, the reduction of violence in institutions, psychopathy and crime across the life span, and issues in elder abuse in Canada and the United States.
