Some forms of therapy may be significantly more effective with Indian patients than others, but this remains relatively unexplored. Decades of intense theoretical and clinical research have contributed to the models of mental illness and psychiatric treatment described in "Major Mental Disorders and Behavior." This research has clearly been beneficial to the treatment of mental illness in patients from the majority culture. Its applicability to Indian patients is, at best, unclear. In contrast to the level of refinement of the research summarized in "Major Mental Disorders and Behavior," research efforts in Indian mental health are at a more basic, pioneering level. Years of research and clinical work will be needed before an Indian mental health program can take full advantage of the technology now available to the majority culture. A number of potentially fertile areas for investigation in Indian mental health are suggested by "Major Mental Disorders and Behavior." With wellcoordinated research efforts aimed at resolving the most fundamental questions in Indian mental health, it is likely that a wealth of treatment technology and basic theoretical knowledge could become available to Indian mental health programs. Before anticipating the most promising research efforts, however, it is necessary to examine the status of current knowledge of Indian mental health, particularly the areas of epidemiology and diagnostic nosology. Modem concepts of mental illness incorporate genetic, social, psychological, biochemical, cognitive, characterological, and functional neurophysiologic dimensions to understand the mechanisms of mental illness. In the majority American culture these dimensions of mental illness have been explored over the past century, but in the field of Indian mental health, most of these dimensions remain in large part unexamined. The diagnosis of mental illness among Indians becomes suspect unless diagnostic instruments are designed to adjust for cultural bias. Though significant work on the dimension of culture has been performed (Shore & Manson, 1983), much more work is needed in this and other as yet unexplored dimensions of major mental illness in Indian people. In attempting to understand the dimensions of mental illness in Indian people, much more work is needed to understand other biological, environmental, and developmental substrates of major mental illness. Personality theories developed to fit the majority culture may or may not have applicability to Indian people. This remains to be explored, as do a myriad of questions about patterns of cognitive function, responses to stress, and other characterological factors. A variety of culture-bound syndromes exist among American Indians and Alaska Natives (Trimble, Manson, & Dinges, 1983). The combinations of environmental, genetic, characterologic, and other factors that produce these syndromes are not fully understood. Investigations of these syndromes, where they exist, may surely contribute to our basic understanding of the interplay of genetic, e...
