107 p., The Millon Clinical Multiaxial Inventory-Third Edition (MCMI-III) currently ranks among the most commonly utilized personality tools. Most of the studies that examined racial/ethnic differences on the MCMI were conducted using the MCMI-I and MCMI-II. While many MCMI studies have explored racial differences, few studies have examined the impact of cultural factors on MCMI-III performance. In the current study, the performance of African Americans (n = 52) and Caribbean Blacks (n = 77) were compared on the Antisocial, Narcissistic, Paranoid, and Delusional Disorder scales of the MCMI-III.
