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