Factor Structure of the MCMI-III

Abstract

The factor structure of the Millon Clinical Multiaxial Inventory (Millon, 1994; MCMI-III) was assessed among 444 African American inpatient substance abusers and constitutes the first factor analysis of the MCMI-III. We found 3 main factors: General Maladjustment, Paranoid Behavior/Thinking With Detached Emotionality, and Antisocial Acting Out. These factors were essentially similar to previous findings of factor studies with the MCMI and MCMI-II across diverse populations. This factor invariance should lend credibility to the revised test and spur additional research into its psychometric properties.
