As narcissism has an one-dimensional approach, long questionnaires are not appropriate in clinical and research use, therefore it is necessary to use shortened questionnaires. The Narcissistic Personality Inventory-16 (NPI-16) is a short self report questionnaire for assessing narcissistic characteristics in non-clinical samples. This research was performed in order to validate this questionnaire in Iran. Materials and Methods: In this cross sectional survey, 342 university students, selected in stratified sampling method, were assessed by Narcissistic Personality Inventory-16 (NPI-16), Neuroticism Extroversion Openness Inventory (NEO) and Millon Clinical Multiaxial Inventory-II (MCMI-II) in 2008. The concurrent validity was assessed through completing a simultaneous MCMI-II test, while the differential validity was assessed as the differential power of test between individuals who had high or low extroversion and high or low agreement characteristics. Retest, splitting and internal consistency coefficients were reported. Results: There was a significant correlation between NPI-16 and MCMI-II scores (α=0.77, P<0.001). The reliability of NPI-16 was proved (P=0.001). Test retest consistency coefficient, splitting consistency coefficient and Cronbach alpha coefficient for internal consistency were estimated to be 0.84 (P=0.001), 0.74 (P<0.001) and 0.79 (P<0.001) respectively. Conclusion: Based on the results, the NPI-16 is an appropriate instrument to screen narcissistic personality traits in Iranian population for pertaining researches Â
