Aggression has long-term negative effects on humanity as a whole. Because of this, aggression has become an important topic of study across many disciplines. Originally conceptualized as being either non-impulsive or impulsive, aggression has become dichotomized as being reactive or proactive. Each form of aggression has been linked to a variety of genetic, psychological, physiological, and neurobiological correlates. Because research continues to grow in these fields surrounding proactive and reactive aggression, it is important to make sure that measurement tools are assessing aggression appropriately across a variety of groups. One such tool that has emerged recently is the Reactive-Proactive Aggression Questionnaire (RPQ; Raine et al., 2006). Though a number of studies exist testing the validity of the RPQ in adolescent and child populations. No such studies exist examining the factor structure and measurement invariance of proactive and reactive aggression in young adult male and females from different ethnicities. The current study assesses factor structure and measurement invariance in multiple groups of young North American adults. Results show that a two- factor, proactive-reactive, structure fits the current data overall. However, measurement invariance is not achieved across the majority of these groups. Meaning that interpretation of reactive and proactive scores is not the same across gender and ethnicity. Limitations and future directions are discussed.
