Child abuse, sexual and domestic violence are among the most destructive experiences afflicting women and children. The wide prevalence of such violence takes an enormous toll on the lives of individual victims as well as the larger society, through innumerable behavioral, health, psychological, and economic consequences. While many groups, organizations, and government agencies have been established to identify, prevent, and treat such violence, our response to these problems has been piecemeal and not optimally successful. A coordinated, cross-disciplinary synthesis of what we know, how we know it, and the necessary next steps is sorely needed to enable us to effectively address these issues. Developed as part of an initiative by former APA President Alan Kazdin, this two-part volume aims to provide consensus recommendations for researchers, practitioners, advocates, policymakers, and all those who seek more effective responses to interpersonal violence. In this volume, eminent scholars use a public health model to examine current societal responses to interpersonal violence. Authors examine the efficacy of medical and psychological treatments for victims, families, and perpetrators, as well as justice system responses to various forms of child abuse, sexual violence, and domestic violence. Interventions are suggested at several levels of prevention, including initiatives designed to eradicate the problem (primary prevention), reduce it among those at risk (secondary prevention), and minimize the negative consequences of violence and stabilize health (tertiary prevention). Finally, the editors present an integrative conclusion that provides a sound foundation for future responses across practice, research, advocacy and policy, at the local and national level.
