The current state of science in violence prevention reveals progress, promise, and a number of remaining challenges. In order to fully examine the issue of global violence prevention, the Institute of Medicine in collaboration with Global Violence Prevention Advocacy, convened a workshop and released the workshop summary entitled, Violence Prevention in Low-and Middle-Income Countries.The workshop brought together participants with a wide array of expertise in fields related to health, criminal justice, public policy, and economic development, to study and articulate specific opportunities for the U.S. government and other leaders with resources to more effectively support programming for prevention of the many types of violence. Participants highlighted the need for the timely development of an integrated, science-based approach and agenda to support research, clinical practice, program development, policy analysis, and advocacy for violence prevention.
