Validity and reliability of the Spanish version of the Displaced Aggression Questionnaire

Background: The Displaced Aggression Questionnaire (DAQ) is an instrument that assesses personality differences in the tendency to displace aggression. This scale is composed of three factors: angry rumination (as affective dimension), revenge planning (as cognitive dimension), and general tendency to engage in displaced aggression (as a behavioral dimension). The present study examined the validity and reliability of the Spanish version of the DAQ. Method: The sample consisted of 429 student and non-student participants. Results: The results showed good psychometric properties, and factor analyses revealed a clear three-factor structure. Further, preliminary data about associations between DAQ scores and indirect aggression and emotion regulation strategies are shown. Conclusions: The scale presents adequate evidence for potential use in a Spanish population. We discuss its utility for research on different types of aggression (e.g., domestic abuse).
