PERSONALITY-DISORDERS IN PATIENTS WITH OBSESSIVE-COMPULSIVE DISORDER IN JAPAN

A total of 75 patients with obsessive-compulsive disorder (OCD) were s tudied in order to investigate the characteristics of QCD symptoms and the comorbidity of personality disorders (PD). Contamination obsessio ns and checking compulsions were most commonly found in patients, of w hom 53% met the criteria for at least one PD. Among comorbid PD, the a nxious-fearful (cluster C) PDs, such as avoidant, obsessive-compulsive and dependent PD, were most prevalent, followed by the odd-eccentric (cluster A) PDs, such as paranoid and schizotypal PD. The patients wit h PD had more severe social maladaptation and concurrent depressive an d anxious symptoms than the patients without any PD, despite the simil ar severity of OCD symptoms. These results are consistent with those r eported in the Western world, and are considered to be relatively stab le cross-culturally.
