The Need for a New Medical Model: A Challenge for Biomedicine

At a recent conference on psychiatric education, many psychiatrists seemed to be saying to medicine, “Please take us back and we will never again deviate from the ‘medical model.’” For, as one critical psychiatrist put it, “Psychiatry has become a hodgepodge of unscientific opinions, assorted philosophies and ‘schools of thought,’ mixed metaphors, role diffusion, propaganda, and politicking for ‘mental health’ and other esoteric goals” (1). In contrast, the rest of medicine appears neat and tidy. It has a firm base in the biological sciences, enormous technologic resources at its command, and a record of astonishing achievement in elucidating mechanisms of disease and devising new treatments. It would seem that psychiatry would do well to emulate its sister medical disciplines by finally embracing once and for all the medical model of disease. But I do not accept such a premise. Rather, I contend that all medicine is in crisis and, further, that medicine's crisis derives from the same basic fault as psychiatry's, namely, adherence to a model of disease no longer adequate for the scientific tasks and social responsibilities of either medicine or psychiatry.
