Previous research suggests that empathy could serve as a mediator in the relation between media violence exposure and social behavior (i.e., aggressive and prosocial behavior). However, conceptualizations of empathy are diverse and empirical findings are mixed. Theory as well as previous research suggests that sympathy, more than empathy, may explain how media violence can affect youths’ aggressive or prosocial behavior. The present study formally tests this assumption using a three-wave longitudinal design with 878 early adolescents. Although neither sympathy nor empathy provided a significant indirect pathway between media violence and social behavior, the findings do show that sympathy is more strongly related to media violence and social behavior than empathy Methodological challenges and suggestions for future research are discussed.
