title: [French empiric criteria for psychoses. I. Situation of the problem and methodology].
abstract: The French classification of mental disorders is a simple nomenclature which provides no definitions nor any other information concerning the categories. The present study describes the methodological guidelines of a nation-wide investigation that was initiated to establish empirical operational definitions for schizophrenia and other non-affective psychoses of classical French nosology.
