Abstract:
Impulsive (IA) and premeditated (PM) aggression reflect functions of aggressive behavior that may have differential correlates and clinical utility. The purpose of this study was to extend the use of the Impulsive/Premeditated Aggression Scale (IPAS) for characterizing aggression in a college student sample. Three hundred forty students completed the IPAS, Buss and Perry's (1992) Aggression Questionnaire (AQ), and measures of childhood maltreatment and negative life events. Principal components analyses supported reliable IA and PM factors. The degree of IA was significantly higher than that of PM. Convergent validity for the IA scale was supported with significant relationships with certain AQ scales. Implications for studying aggressive functions in this age group may inform violence prevention and treatment on college campuses.
