This study investigated the construct validity of the Narcissistic Personality Inventory against the Revised NEO Personality Inventory to test the hypothesis that narcissistic and nonnarcissistic people have different personality profiles. The two inventories were administered to 96 male and 92 female undergraduates. Multivariate as well as univariate analyses of variance indicated that the Revised NEO Personality Inventory profiles were significantly different for narcissistic and nonnarcissistic groups which supported the construct validity of the Narcissistic Personality Inventory.
