Diagnosis of severely ill inpatients in China. A collaborative project using the structured clinical interview for DSM-III (SCID).

The purpose of this project was to investigate any differences in diagnostic practice between Chinese psychiatry and Western psychiatry with regard to severe psychiatric illness among Chinese inpatients. Specifically, the project aimed to look at differences between the Chinese diagnostic system and DSM-III. This study stemmed partly from a desire to investigate the supposed "overdiagnosis" of schizophrenia in China relative to the West. A second objective was to use a structured interview format to obtain clinical data for DSM-III and to decide whether a translated version of such an interview offered promise for future transcultural psychiatric research. Forty-two inpatients on a psychiatric ward in China were interviewed by an American psychiatrist assisted by a Chinese faculty translator and a diagnosis was made using the Structured Clinical Interview for DSM-III. A Chinese professor of psychiatry who was blind to the structured interview results interviewed each patient independently and assigned a diagnosis within the current Chinese system. Follow-up data was obtained on 69% of the patients after 16 months to check for stability of diagnosis. Results of the study pointed to less diagnostic disagreement than previous work had predicted. On cases where there was disagreement, DSM-III diagnoses tended toward affective disorders or atypical forms of psychosis while the Chinese diagnosis tended towards schizophrenia.(ABSTRACT TRUNCATED AT 250 WORDS)
