Introduction Unplanned reactive aggressive acts are a clinical feature of particular interest in patients with borderline personality disorder (BPD). The early identification of personality traits correlated to aggressive behavior is certainly desirable in BDP populations. This study analyzes a clinical sample of 122 adult outpatients with BPD referred to Adult Mental Health Services of the Department of Mental Health of Bologna, in Italy. Methods The study examines the relationship with personality facets of the DSM-5 alternative model for personality disorders (AMPD), Personality Inventory for DSM (PID-5), with respect to the four main components of aggression measured by the Aggression Questionnaire (AQ): hostility, anger, verbal and physical aggression. Using robust regression models, the relationships between PID-5 facets and domains and the aggression components under consideration were identified. Results Verbal and physical aggression in our sample of BPD outpatients is mainly associated to PID-5 antagonism domain. Physically aggressive behavior is also related to callousness facet. Conclusions The traits most consistently associated with aggression were the domain of Antagonism and the facet of Hostility. The study findings highlight the need for clinicians working with individuals with BPD to pay particular attention to traits of hostility, callousness, and hostility to understand aggression.
