[Diagnostic criteria for psychiatric research: RDC (Research Diagnostic Criteria). French translation and adaptation by M. Ansseau].

This article represents the French translation of the Research Diagnostic Criteria, a set of operational criteria for 24 psychiatric disorders developed by researchers at the New York State Psychiatric Institute and Columbia University (New York) to permit the selection of homogeneous samples of patients presenting with a defined psychiatric illness. The Research Diagnostic Criteria are especially focussed on depressive disorders, defining the major depressive disorder, which comprises 10 non exclusive subtypes. These criteria currently represent the most widely used nosologic system for clinical research in psychiatry, allowing for comparison of results and facilitation of replication by different research teams.
