The MMPI and the MCMI in the evaluation of narcissism in a clinical sample.

Narcissistic and nonnarcissistic groups of psychiatric patients (n = 35 in each group) were formed on the basis of a criterion comprised of clinical judgment and scores on the Narcissistic Personality Inventory and compared on the Minnesota Multiphasic Personality Inventory (MMPI) and the Millon Clinical Multiaxial Inventory (MCMI) profiles and on six special narcissism scales. Significant profile differences between narcissists and nonnarcissists were obtained on the MMPI and MCMI. Four of the six narcissism scales produced significant differences between the two groups.
