Personality disorder diagnoses using DSM-III-R in a Japanese clinical sample with major depression

Abstract

To investigate the availability of DSM-III-R Axis-II diagnoses in Japan, DSM-III-R personality disorders (PDs) were diagnosed in a large sample of Japanese out-patients with major depression. The SCID-II was administered to 118 consecutive out-patients with major depression. In general, the frequency of PD according to DSM-III-R criteria in this study was within the range of frequencies reported in North American and European studies. However, schizoid and narcissistic PDs were more frequent in this study. DSM-III-R diagnoses of PD would also be potentially useful for assessing personality disturbance in Japan. The DSM-III-R criteria for schizoid and narcissistic PDs may not be suitable for Japanese samples.
