he present study aimed to assess the criterion validity of the Reactive-Proactive Aggression Questionnaire (RPQ) in a Turkish sample of preadolescents. Participants consisted of 379 middle school students (190 boys and 189 girls) aged 11 to 15 years. In this study, the Strengths and Difficulties Questionnaire (SDQ) was used as the criterion instrument. Findings from stepwise regression analysis revealed that conduct problems were the strongest predictor of both reactive and proactive aggression. Additionally, reactive aggression was uniquely predicted by emotional symptoms and hyperactivity, whereas proactive aggression was uniquely predicted by prosocial behavior. Our results indicate that the RPQ has acceptable criterion validity for use in Turkish preadolescents.
