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.     

Overt and relational forms of reactive aggression in adolescents: Relations with temperamental reactivity and self-regulation

This study examined whether overt and relational forms of reactive aggression were differentially related to adolescents’ temperament. Measures of adolescents’ temperament and aggression were completed by 670 adolescents (369 females), ages 10–17, and their mothers. Effortful control and fearfulness were inversely associated only with reactive–overt aggression, whereas frustration proneness was more strongly linked with reactive–relational aggression. Furthermore, amongst younger adolescents, effortful control had a larger association with reactive–overt aggression when fearfulness was low, whereas frustration proneness had a stronger relation to reactive–relational aggression when effortful control was high. The differential relations between the two forms of reactive aggression (i.e., overt and relational) and effortful control or fearfulness are discussed with respect to variations in the riskiness and the social competence required to implement these aggressive actions.
