title: [The problem of representiveness in epidemiological research in psychiatry].
abstract: A group of schizophrenic patients registered by the city psychoneurological center (Petrozavodsk) is compared to a standard sample. It is shown that there is a possibility of defining to what extent the test group differs from the representative one and by what the differences are determined. In accordance with this, the limits of the use of the research data are outlined.
