Burgeoning directions for the prevention of youth violence. Introduction

Despite focused efforts toward the prevention of youth violence within the United States, it continues to adversely affect the lives of children and families within our communities and society at large. The articles in this issue address risk and protective factors that affect violence among urban youth to inform prevention and treatment. Pathways to youth violence are complex and may begin early. Prevention efforts in school, family, and community settings that address risk and protective factors within a socially, culturally, and ecologically valid context early in human development are crucial. While challenges remain for the prevention of youth violence, research suggests opportunities to improve our efforts. Federal agency initiatives in partnership with communities are currently underway to increase the knowledge base and advance prevention of youth violence among diverse populations.
