A recent surge in narcissism research by personality and clinical psychologists has been prompted thanks to the development of the Narcissistic Personality Inventory )NPI-40). The purpose of the present study is to investigate the psychometric properties of the Persian version of NPI-40.
A total number of 410 (234 male and 176 female) students in the academic year 2011-2012 with an average age of 25-26 years were selected through stratified sampling to serve as the subjects of this study. They completed NPI-40, Millon Clinical Multiaxial Inventory–III (MCMI-III) and Extraversion Agreeableness Subscales of Five-Factor Inventory (NEO-FFI). The reliability coefficients of internal consistency, test-retest and concurrent validity were also reported.
The results showed that the total NPI-40 test-retest reliability and internal consistency were 0/81 and 0/77, respectively. The correlation coefficients between NPI-40 and MCMI-III and Extraversion Agreeableness Subscales of NEO-FFI were also reported at 0/82, 0/73 and 0/68, which indicate a satisfactory convergent validity for NPI-40.
Confirmatory factor analysis results showed that the seven-factor model of NPI-40 fits the Iranian sample. MANOVA results also indicated that the total score of Narcissism for men is significantly higher than the one for women.
