Cross-cultural generalizability of the Reactive-Proactive Aggression Questionnaire (RPQ).

In this study, we assessed the cross-cultural generalizability of the Reactive-Proactive Aggression Questionnaire (RPQ) and tested the hypotheses that boys show higher levels of proactive aggression with increasing age and that a two-factor (reactive-proactive) structure will be observed in an East Asian population. We administered the RPQ to 5,615 male and female 11- to 15-year-old schoolchildren. CFA demonstrated a good fit of the two-factor reactive-proactive model. Proactive aggression increased significantly with age in boys but not girls, whereas reactive aggression showed no gender difference and only a minimal age increase. Results suggest the presence of meaningful differences between these aggression subtypes and the generalizability of the RPQ in an East Asian population.
