Abstract
This study investigated the association between maladaptive personality traits, personality disorders (PDs), schizophrenia, and the risk of aggressive behavior. Ninety-four patients with a history of violence and 92 patients with no history of violence underwent a multidimensional baseline assessment. Aggressive behavior was monitored during a 1-year follow-up through the Modified Overt Aggression Scale. The Violent group scored significantly higher than the Control group on the Millon Clinical Multiaxial Inventory (MCMI-III) Antisocial, Sadistic, Borderline, and Paranoid personality scales. Irrespective of any history of violence, patients with PD as a primary diagnosis displayed more aggressive behaviors than those with a primary diagnosis of schizophrenia during the follow-up. Furthermore, the most significant predictor of aggressive behaviors over time was endorsing a primary diagnosis of PD. Identifying the crucial risk factors for violent recidivism would contribute to reducing aggressive behavior in this population.Keywords
