Abstract:
Psychiatric manifestations of 72 CATEGO Class S+ schizophrenics were studied using a syndrome check list. Comparison of syndromic manifestations with other published works revealed significant cross-cultural differences. It was observed that Indian CATEGO S+ patients had significantly less depression, tension and anxiety. Differences in nuclear syndrome and Schneider's First Rank Symptoms were also visible. Difficulties in rating syndromes of affect and subcultural delusions are commented upon. Usefulness and applicability of the Present State Examination as a tool of assessment in the transcultural context are discussed.
