Deviant Peer Affiliation: A Newly Verified Mechanism by Which Violent Video Game Exposure Affect Aggressive and Prosocial Behavior.

Past research has provided abundant evidence that violent video game exposure (VVGE) increases aggressive behavior and decreases prosocial behavior. So far, these effects have been explained mainly as resulting from changes in the existing knowledge structures of cognition, affect, or personality, such as desensitization to violence, empathy deficits, or impulsivity deficits. Following the extended General Aggression Model (GAM), the present research examined the role of deviant peer affiliation in VVGE's effects on aggressive and prosocial behavior. A total of 2,152 (46.4 percent male) Chinese children and adolescents completed a self-reported scale for VVGE, deviant peer affiliation, trait aggression, and prosocial behavior. Structural equation modeling was used to analyze the data. The results showed that deviant peer affiliation mediated the effects of VVGE, thus supporting the new paths of GAM and broadening the current understanding of the consequences of VVGE.
