Le biais d’attribution d’intention hostile et les traits de la personnalité limite : Une étude de potentiel relié aux évènements.

This study investigates the cognitive processes underlying reactive aggressive behaviour in a population with borderline personality disorder (BPD) traits, but not necessarily with a BPD diagnosis. Previous research has shown an association between the hostile intent attribution bias (HIB) and aggressive behaviour, but this relationship has not yet been examined in a population with BPD traits. To achieve our goal, we conducted a methodological replication of Gagnon et al.’s (2016) study proposing an event-related potential (ERP) method for assessing BAIH. The hostile expectation violation task used elicits an N400 component, representing a negative deflection in the ERPs plot when the subject’s expectations are violated. The second objective was to test the hypothesis that the HIB would mediate the relationship between BPD traits and the reactive aggression. Sixty-three individuals participated in the study. The PAI-BOR measured the participants’ BPD traits, and the RPQ measured their tendency to react aggressively. The results support the relationship between BPD traits and reactive aggression, and between HIB and reactive aggression. The expected mediating effect was not found between the N400 effect of the non-hostile condition measuring hostile expectation violation, and the relationship between BPD traits and reactive aggression. Further studies are needed to confirm that effectiveness of interventions based on interpretations in social situations. (PsycInfo Datab...
