Exposure to violence and victimization and the use of violence by adolescents in the United States.

Violence by adolescents in the United States is of growing concern. Despite a decrease in the rate of violence and death by firearms, firearm injuries are the second leading cause of death among Americans age 15 to 24 and the third leading cause of death among 10- to 14-year-old children. Although there are many factors associated with the use of violence by youths, exposure to violence and victimization has consistently been a predictor of the use of violence, as well as intentions to use violence, carrying a gun, and having attitudes accepting of the use of violence and aggressive behavior to resolve conflict. Adolescents' families, friends, neighborhoods, schools, and the media provide sources of exposure and victimization related to the use of violence. The cultural transmission of deviant behavior theory establishes a framework for understanding the influence of exposure to violence and victimization from these sources on adolescents' use of violence.
