Introduction: Pow Meng Yap and the culture-bound syndromes.

PM Yap's most significant intellectual achievement was his development of the concept of the culture-bound syndrome, which synthesized years of research into transcultural psychiatry, and situated this work within this field by drawing on elaborated nosological schema that challenged some of the ethnocentric assumptions made by previous psychiatrists who had tried to understand mental illnesses that presented in non-western cultures. This introduction to Yap's 1951 paper emphasizes that Yap needs to be understood as working within the western tradition of transcultural psychiatry, and argues that his English training and his continual engagement with western psychiatric and philosophical frameworks is the best way to conceive of his contributions to this field. Yap's paper, republished below as the Classic Text, was his first foray into comparative transcultural psychiatry.
