The main purpose of the present study was to investigate the diagnostic concepts of taijin‐kyofu‐sho (TKS) and social phobia, by comparing the clinical diagnosis of TKS and the operational diagnosis of Diagnostic and Statistical Manual of Mental Disorders (3rd edition, revised; DSM‐III‐R). Three evaluators conducted semistructured interview for DSM‐III‐R (SCID axis I and II, the Japanese version) to 88 outpatients who visited Jikei University Daisan Hospital, Japan, over a period of 1 year, requesting Morita therapy. The patients were also independently diagnosed by three psychiatrists to identify TKS. A total of 65.8% of 38 cases of TKS were diagnosed as social phobia. Among the neurotic TKS cases, the percentage was high at 81.5%, while among the delusional TKS cases it was 27.3%. A total of 42.1% of the TKS cases were diagnosed as mood disorder; 60.5% of the TKS cases presented some axis II disorders, among which avoidant personality disorder was the most prevalent (31.6%). There was no significant difference between the neurotic and delusional subtypes of TKS, regarding comorbidity with axis I diagnoses. As for axis II diagnoses, delusional TKS patients had a higher rate of comorbidity with paranoid personality disorder, although they demonstrated very similar trends in comorbidity with all other personality disorders. In the diagnostic system of DSM‐III‐R, it is highly likely that the neurotic and delusional subtypes of TKS will be seen to correspond to different diagnostic categories.
