[Integrated lists of taxonomic evaluation criteria: LICET-S and LICET-D]

LICET-S and LICET-D are diagnostic instruments containing all diagnostic criteria for two major groups of disorders. LICET-S assembles the criteria proposed for non-affective psychoses in 9 different systems. LICET-D integrates the criteria defining the depressive categories listed in 7 different systems. Initially constructed to elaborate empirical criteria for specific categories pertaining to traditional French nosology, the two lists also permit to formulate diagnostic decisions according to 9 respectively 7 classification systems, on the basis of the algorithms defining each of the systems under discussion. The authors present the rationale that led to the construction of the LICET-system. They describe the composition of the two lists and the guidelines for use of the system. They finally illustrate the utility of the instruments on the basis of results obtained in recent investigations.
