title: [The Mannheim Cohort Project--prevalence of psychogenic diseases in cities].
abstract: For the purpose of our research project the term 'psychogenetic disorders' covers psychoneuroses , character neuroses in a broader sense, and functional-vegetative as well as psychosomatic affections. So far information concerning basic descriptive-epidemiological data, especially the frequency of occurrence and the dependence upon demographic variables of the above mentioned disorders, is insufficient and controversial. Even less satisfactory is our information on the progress of these disorders. The specific difficulty with the diagnostic apperception of these disorders in particular requires field research within the entire population. Only by means of such a very expensive procedure can valid information on the true prevalence or incidence of the above mentioned disorders be obtained. Moreover, for a follow-up design each test subject must be examined several times by highly qualified experts, each examination requiring his personal presence. The "Mannheimer Kohortenprojekt" involves six hundred test subjects, two hundred each born in 1935, 1945, and 1955, selected at random from the 'normal' general population. They were examined with the aid of a structured interview schedule oriented on psychoanalytic principles and with other instruments (lists of complaints, inventories of life events, FPI-tests, etc.). Results from the first three-year investigation period include: Out of the total of six hundred test subjects twenty-five per cent are "cases". Women are significantly in the majority. Apparent is an obvious connection between different types of complaints and the social class of the test subject. Identified disorders show correlations with life events on the one hand and with early childhood disturbances on the other.
