Environmental and contextual influences on school violence and its prevention.

School violence has received unprecedented attention in recent years, particularly since the infamous events unfolded in Littleton, Colorado at Columbine High School. For many Americans, such events were not imagined possible while for others, they confirmed the need for urgent and careful examination of the nature and scope of school violence. It appears, however, that school violence research has been relegated to the individual level of analysis. In this introduction to the special issue about the environmental and contextual factors related to school violence, the authors examine what we know about school violence, how school violence has been addressed, and argue that environmental factors must be part of research and intervention in this area. Finally, the contributions of the articles included in this special issue are discussed.
