This study examined psychometric properties of the MCCI (Millon College Counseling Inventory) (T. Millon, Strack, C. Millon, & Grossman, 2006), as applied to students from ethnically and culturally diverse backgrounds. The sample (N = 209, Mean age = 23.81, 74% identified as ethnic minority) was derived from students presented for counseling services in a large southeastern state university. Cronbach alpha analyses across all scales were robust; the overall mean alpha coefficient was 0.73, with the vast majority demonstrating alpha coefficients of 0.70 or higher. An analysis of principal components was conducted, as well to examine the instrument's underlying factor structure. This yielded a seven-component solution explaining 70.15% of the total variance. Communalities ranged from 0.403 to 0.876 and the rotated component pattern demonstrated simple structure. In summary, when applied to an ethnically diverse sample, the MCCI yielded a performance reflective of the original standardization sample, suggesting its appropriateness for use with an ethnically diverse student body.
