This course focuses on the assessment, development, prevention, and treatment of youth violence among children and adolescents. Understanding and preventing youth violence is a major focus of the nation's policy agenda and involves research and practice in the mental health, public health, psychiatry, and criminal justice communities. Using a multidisciplinary approach, the course reviews the biological, social, and psychological underpinnings of youth violence, and discuss how policy makers and practitioners at all levels deal with this problem.
