Factor structure of the MCMI among personality disordered outpatients and in other populations.
This study examined the factor structure of the Millon Clinical Multiaxial Inventory (MCMI) for a sample (N = 60), which consisted largely of personality disordered outpatients. Results are integrated with previous studies to identify the underlying MCMI dimensions across differing psychiatric populations. Three principal axis Varimax rotated factors emerged from the current study: affectively charged general maladjustment; impulsive acting-out style; and psychotically tinged isolation. Comparison with results of previous studies that involved four diverse samples indicated a large amount of stability for scales that load on the first factor. Factor two shows much less consistency across the five studies, but frequent reappearance of the drug abuse and other acting-out scales suggests a general dimension that reflects acting-out substance abuse. Across studies the third factor shows even more inconsistency, although there is some evidence for a social detachment pattern.
