[Findings from a psychiatrist's screening of selected groups of the adult population in a number of regions of the USSR].

The paper is concerned with the results of a total study of representative sample groups of the population made by a psychiatrist. During such examinations 1872 individuals who demonstrated mental disorders were found. Only a part of them were previously registered in a psychoneurological dispensary. A comparison of the number of previously registered patients in the different groups of population made it possible to conclude that the detection of patients is associated with severity of the disease and with social activity of different groups of population.
