Racial differences on the MCMI in an outpatient clinical sample.

In this study, we extended previous research on racial differences on the Millon Clinical Multiaxial Inventory (MCMI) which focused on psychiatric inpatients. Subscale scores were compared for Black and White outpatient males on the MCMI. Age, education, and employment status were controlled. Results showed that Blacks scored significantly higher than Whites on the Narcissistic, Aggressive, Paranoid, Drug, and Psychotic Delusion subscales. Results are interpreted in terms of the larger body of research on racial differences on personality instruments. Clinical implications and the need for further research are discussed.
