[Disciplinary organization of medical sociology--a contribution to the dialogue with social medicine].

According to Karl Popper scientific disciplines are characterized by a body of observational knowledge, a specific methodology and terminology and a set of more or less successful theories. This article tries to delineate the disciplinary structure of medical sociology in terms of five important areas of knowledge: 1. sociology of health lifestyles (prevention); 2. sociology of patients careers (rehabilitation); 3. sociology of client-professional interaction (diagnosis, therapy); 4. sociological (social epidemiological) studies of causes of health and disease; 5. sociology of health care systems. It is argued that intensified exchange according to these areas between the academic disciplines of medical sociology and social medicine is needed to generate a significant impact on future training and research both in medicine and in public health.
