Violence Exposure Across Contexts: Unique and Interactive Effects on Adolescent Aggression

Family conflict is a relational process that may shape adolescent aggression through disruptions to emotional security, reinforcement of coercive interactions, and the development of aggressive scripts and beliefs. Because adolescents are also exposed to violence in community and media contexts, these broader ecological experiences may independently contribute to aggression or alter the influence of family conflict. We analyzed two waves of data collected six months apart from 345 U.S. middle school students and examined whether exposure to family conflict was associated with an increase in adolescent aggression, and whether this association was stronger than effects of community and media violence exposure. We also examined interactive effects to test if violence exposure in community and media contexts operates independently or interacts with family conflict to alter its effect on adolescent aggression. Family conflict and community violence exposure independently predicted later aggression after accounting for baseline aggression. Family conflict made the largest relative contribution among the three contextual predictors. A significant interaction between family conflict and media violence exposure indicated that family conflict was associated with later aggression at low, but not high, levels of media violence exposure; no other interactions were significant. These findings position family conflict as a particularly salient relational context for adolescent aggression while showing that its influence may depend on violence exposure in other social contexts. Prevention efforts should prioritize reducing hostile and coercive family interactions while attending to media and other social contexts that may reinforce, normalize, or otherwise alter family conflict effects on adolescent aggression.
