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).
