title: Diagnostic utility of the MCMI-I and MCMI-II with psychiatric outpatients.
abstract: Research indicates that the Millon Clinical Multiaxial Inventory (MCMI-I) lacks diagnostic accuracy when compared to clinically generated DSM-III-R diagnoses. This shortcoming is most evident for the identification of psychotic disorders. The MCMI-II was designed to reflect more accurately the DSM-III-R diagnostic formulation, but its diagnostic efficacy has yet to be determined with clinical samples. In the present investigation, two consecutive samples of psychiatric patients who were attending an outpatient day treatment program were administered either the MCMI-I (N = 39) or the MCMI-II (N = 37). MCMI diagnoses were compared with clinician-generated DSM-III-R diagnoses. Relative to clinical judgment, both versions of the MCMI underestimated the incidence of psychotic disorders and overestimated the incidence of nonpsychotic disorders and personality disorders.
