This study examined the effect of exposure to violence on juveniles. It was specifically concerned with juveniles' perceptions of violence in schools and communities and how exposure to violence served as a risk factor for juvenile drug and alcohol use and participation in other delinquent activities. It also sought to develop a more complete picture of the context and consequences of violence in schools. The data for this study were drawn from the NATIONAL SURVEY OF ADOLESCENTS IN THE UNITED STATES, 1995 (ICPSR 2833). The data were collected through a national probability telephone sample of 4,023 juveniles and their parents or guardians. The current study drew primarily on the questions that were asked about respondents' experiences witnessing violence, their own victimization, peer and family deviance, their own delinquent activities, and drug and alcohol use.
