Examining the relationships between impulsivity, aggression, and recidivism for prisoners with antisocial personality disorder

Abstract Impulsivity impacts multiple life domains and is related to criminal and problematic behaviors. In forensic contexts, impulsivity and aggression are often associated with psychiatric issues. Personality disorders are related to worse prognosis, increased relapse, and damage to relationships. The aim of this study was to clarify the impact of psychopathy, impulsivity, and aggression on recidivism, and to investigate the relationships between these dimensions in prisoners with and without Antisocial Personality Disorder. The forensic sample included inmates with (n = 50) or without Antisocial Personality Disorder (n = 50). We measured psychopathic traits with the Triarchic Psychopathy Measure (TriPM), impulsivity with the Barratt Impulsiveness Scale (BIS-11), and aggression with the Impulsive/Premeditated Aggression Scale (IPAS). There were significant between-group differences regarding premeditated aggression and attentional impulsivity. For inmates with antisocial personality disorder, impulsive aggression was related to recidivism (number of times in jail). Their level of psychopathy was related to premeditated aggression and motor impulsivity. Impulsive aggression, like attentional impulsivity, was related to recidivism only for inmates with antisocial personality disorder. In conclusion, psychopathy is associated with recidivism; moreover, impulsivity and aggression are central to recidivism for these individuals.
