This study examined the relationship between playing violent video games and antisocial behavior in adolescents. The study found that 26% of adolescents reported playing violent video games, and frequent exposure to violent video games was associated with increased risk of seriously violent behavior, antisocial behavior, and delinquency. The association between violent video games and externalizing behaviors was mediated by character identification, such that identifying with violent characters increased the effects. However, the study was limited by its cross-sectional design and reliance on self-reports.
