Psychometric properties of the Aggression Questionnaire: A replication in a sample of partner-assaultive men in psychological treatment

The Aggression Questionnaire (Buss & Perry, 1992) is one of the most widely used validated self-report measures to assess aggression. This study analyzes the factorial structure, internal consistency, and convergent validity of the AQ in a Spanish sample with high levels of violence. The questionnaire was administered to 767 partner-assaultive men undergoing psychological treatment. The results of the confirmatory factor analysis supported the four-factor structure. Also, positive correlations between the AQ and other instruments measuring aggression were found, finding that aggression and anger decrease with age in this sample. The results obtained showed that the AQ is a suitable instrument to assess aggression, anger, and hostility in partner-assaultive men.
