The MCMI-II and race

Abstract

In this study, we investigated MCMI-II profile differences in a sample of 65 Black and 164 White psychiatric inpatients. A multivariate analysis of variance (MANOVA) yielded a significant multivariate effect associated with race, with Black patients scoring significantly higher on the Histrionic, Narcissistic, Paranoid, Drug Dependent and Delusional Disorder scales. A second MANOVA was conducted on these 5 scales with a smaller sample of 46 Black and 46 White patients, who were matched for primary Axis I discharge diagnosis and matched for substance abuse comorbidity. This MANOVA did not yield a significant multivariate effect associated with race, and scale differences were attenuated.
