The aggression question, as a primary individual’s component, interests several risk behaviors in different life span phases. The necessity to measure and evaluate the aggression, in its different components and forms, is more and more evident in order to explore appropriately the different behaviors and emotions that interfere with health and well-being itineraries. The Aggression Questionnaire (AQ, Buss and Perry, 1992) seems to be still nowadays one of the more utilized instruments in the evaluation of the different aggression levels in different live ages. The main goal of the present study is to provide a further contribution to the Italian validation of this instrument, by investigating the factorial structure invariance in two different age ranges: adolescents/late adolescents (N = 319) and youths (N = 417). The results were very satisfying, considering the separate and simultaneous verification of the model in both age groups. Further investigations would deepen the contextual specificities of the instrument.
