Specificity concepts reflected by psychoanalytic epidemiology.

The issue of whether there are specific constellations of intrapsychic conflicts, personality structures and symptom patterns within the general population is investigated by means of a representative epidemiological field cohort study. Out of a population of 600 adults three groups are compared: probands who are suffering from functional cardiac symptoms, those who are suffering from headaches and a sample of 'healthy' probands. The interview protocols of these probands were examined to identify typical conflict patterns. Finally the raters had to give a 'blind' overall diagnosis. Six criteria differentiating the 3 samples were identified and the 'blind' overall ratings were compared with the actual diagnosis. The results are discussed with regard to a hypothesis from the literature.
