Qualités psychométriques d’une version francophone du « Displaced Aggression Questionnaire »

IntroductionThe Displaced Aggression Questionnaire is currently the only self-report instrument to measure individual tendency to displace aggression. It is composed of three factors, which assess an affective dimension (angry rumination), a cognitive dimension (revenge planning) and a behavioral dimension (displaced aggression).ObjectiveTo adapt a French translated version of the Displaced Aggression Questionnaire and test the psychometrics.MethodIn this study, we recruited 191 adults in the community. The questionnaire has been adapted and validated with respects to guidelines for the process of transcultural adaptation and validation of self-report measures. A principal component analysis has been used to assess the structure of the French version of the questionnaire.ResultsAfter taking into account one item that has not loaded onto any of the three expected factors, the principal component analysis confirmed the hypothesized three-factor structure for the French version of the questionnaire according to the original structure of the scale. It has been named Questionnaire d’Agression Déplacée in French. Results showed good psychometric qualities for the internal consistency, the discriminant and concomitant validity and the reliability.ConclusionBased on these positive results, this version can already be used by French speaking researchers.
