||While there has been some research demonstrating the positive effects of playing video games, much of the research examining the potential link between violent video games and aggression suggests that playing violent video games is a contributing factor towards increased aggression and hostility (e.g., Anderson & Dill, 2000). The General Aggression Model (GAM) postulates that this effect can be accentuated by certain personality traits and previous research suggests personality traits might moderate the negative effects of violent video games; specifically high neuroticism, low agreeableness, and low conscientiousness (Markey & Markey, 2010). The current study looked at whether or not personality disorders that are highly associated with the previously mentioned traits moderate the increased hostility seen after playing a violent video game; specifically Antisocial personality disorder (ASPD), Borderline Personality Disorder (BPD), and Paranoid Personality Disorder (PPD). One hundred and seventy-one participants were asked to complete a self-report measure for the three disorders and then played either a violent or non-violent video game for 20 minutes. They were then asked to complete a self-report measure of hostility. Regression analyses showed a main effect of the violent video games in leading to hostility; however, there were no main effects for any of the personality disorders and the interactions between personality disorders and violent video games were also non-significant. These results could indicate a problem with the validity of the GAM but, more likely, reflect the lack of variability in clinical symptoms among the sample.
