Abstract

SANZ, Jesús. Some troubles with the use of the Spanish adaptation of Millon Clinical Multiaxial Inventory-II (MCMI-II) for diagnostic purposes. Clínica y Salud [online]. 2007, vol.18, n.3, pp.287-304. ISSN 2174-0550.

One of the aims of Millon Clinical Multiaxial Inventory-II (MCMI-II) is to identify the best diagnosis for patients. In order to achieve this goal, the MCMI-II suggests cutoff points in terms of base rate (BR) scores that are supported by satisfactory results in a diagnostic validity study. The three editions of the Spanish adaptation of the MCMI-II show a number of inconsistencies concerning norms to translate raw scores into BR -misprints, high discrepancies with American norms, change of norms among editions. There is also a suggestion for diagnostic BR cutoff points which validity is not supported by any empirical research. This paper analyzes problems and implications stemming from this situation. Some suggestions and recommendations are also made to overcome those problems -the most important of which is not to use the Spanish adaptation of the MCMI-II for diagnostic purposes until data to support diagnostic validity have been gathered.
