Investigated the validity of the Narcissistic Personality Inventory (NPI) in a psychiatric sample. Fifty psychiatric patients were given the NPI as part of a routine psychological evaluation. Correlations between the NPI and the basic personality style scales of the Millon Clinical Multiaxial Inventory (MCMI) were obtained; the largest correlation was between the NPI and the narcissism scale of the MCMI (r = .66, p less than .001). When classified into the low and high narcissistic groups, there was 74% agreement between the NPI and narcissistic scale of the MCMI. These results provide further support for the construct validity of the NPI.
