Abstract
Validation of the spanish version of the aggression questionnaire. The main aim of this study was to analyze the psychometric properties of the aggression questionnaire (AQ) (Buss and Perry, 1992) using a large sample of students from different educational settings in the community of Madrid (N= 1.382, 49% males & 51% females. This questionnaire, which has been used extensively in many studies of aggressive behavior in youths and adolescents, is one of the most valid self-report techniques to assess two types of aggression: physical and verbal; and two types of emotions associated with aggression: anger and hostility. The results of this study provide psychometric support for the use of the Spanish version of this questionnaire as a reliable and valid instrument to assess different levels of aggression, anger and hostility in youths and adolescents.
