COMORBIDITY BETWEEN OBSESSIVE-COMPULSIVE DISORDER (OCD) AND PERSONALITY-DISORDERS

The aims of the present study were to examine the frequency of persona lity disorders in 36 patients with obsessive-compulsive disorder (OCD) , and to investigate whether patients with a coexisting personality di sorder could be characterized by certain personality traits assessed b y means of the Karolinska Scales of Personality (KSP). In total, 27 (7 5%) of the OCD patients fulfilled the DSM-III-R criteria for a persona lity disorder, and 13 patients (36%) had an obsessive-compulsive perso nality disorder. Subjects with a comorbid personality disorder had sig nificantly higher scores on most of the KSP scales, including all anxi ety scales, as well as scales measuring indirect aggression, irritabil ity, guilt and detachment, whereas subjects without personality disord ers did not differ significantly from healthy controls with regard to personality traits.
