The exposure of children to violence has potentially far-reaching effects on future mental, emotional, and behavioral health. Using 2 large national surveys, Finkelhor and colleagues examined trends in violence victimization and exposure between 2003 and 2008. There was a decrease in the annual prevalence of physical assault, psychological and emotional abuse, sexual assault, and exposure to community violence. There was no change in the prevalence of physical abuse or neglect, dating violence, witnessing domestic violence, or exposures to shootings. However, the prevalence of robbery and witnessing physical abuse of a sibling did increase during this period. These declines are consistent with trends apparent in the National Crime Victimization Survey, which since 2003 have shown marked drops in 12- to 17-year-old adolescents reporting assaults, sexual assault, and property crime.
