Antisocial Personality Disorder (APD) is characterized by a general pattern of disregard and transgression of the rights of others, appearing in childhood or early adolescence and continuing into adulthood. This disorder generates a severe handicap in all spheres of life. The aim of this study was to describe the sociodemographic, clinical, psychometric and therapeutic characteristics of patients with ASPD who were hospitalized in a psychiatric unit. A psychometric evaluation was carried out using six scales. APS is a major concern for clinicians in the hospital setting. A better understanding of the specificities of patients suffering from this condition could improve their management.
