Although diagnosis is integral to the theory and practice of psychiatry, social scientists have not developed a comprehensive approach to diagnosis. This paper presents a preliminary outline of the issues which a sociology of diagnosis should integrate. These include bias and social control in psychiatric diagnosis, diagnosis as part of a new extension of the biopsychiatric medical model, and flaws in contemporary diagnostic categorization. These issues are then viewed in terms of professional practice styles, diagnostic biases, psychiatry's professional dominance over (...) the mental health field, and psychiatric hegemony over the clinical interaction with patients.
