The authors of the chapters in this book do not diminish psychology and psychiatry, even though there is the acknowledgment that basic concepts in these fields have traditionally been socially rather than scientifically constructed. Science cannot provide us with factual, static definitions of concepts in psychiatry, because the concepts are fluid and negotiated matters of value, not fixed matters of fact. Cultural psychopathology research, as discussed in the first part of the book, serves as an important site for integrating ethnographic, observational, clinical, and epidemiologic research approaches. The increasing cultural diversity of the United States and the massive movement of people around the globe provide both an opportunity and an imperative for cultural psychopathology research.
