Where do psychiatrists and other mental health professionals turn for information regarding how to predict and, more importantly, prevent violence? What are the best ways to treat victims of violence? This issue, a product of the American Psychiatric Association's Task Force on Violence, presents a comprehensive examination of the full range of violence-related issues that mental health practitioners may confront in their practice. The contributors provide guidance on how to assess and manage violent patients, how to predict the risk for violence, and how to treat victims of violence. They review both the victim and perpetrator aspects of sexual violence, explore the special issues surrounding family violence, and more. This is the 86th issue of the quarterly journal New Directions for Mental Health Services.
