Objective: Despite its importance as a psychological construct, narcissism have been inconsistently defined and measured across studies. Overly narrow construct definition of pathological narcissism and insufficient measurement lead Pincus et al. (2009) to develop Pathological Narcissism Inventory (PNI). Which is a multidimensional measure of pathological narcissism that assesses both overt and covert expressions of narcissistic vulnerability. The aim of this study was to adapt PNI into Turkish language and investigate the validity and reliability indicators. Method: The Turkish version of Pathological Narcissism Inventory was applied to 518 (205 male) university students. Cronbach alpha and test-retest reliability coefficients were calculated. Confirmatory and exploratory factor analyzes have been carried out to determine the factors. The Narcissistic Personality Inventory (NPI) and the Bell Object Relations and Reality Assessment Scale (BORRTI) object relational form were used for evaluation of validity. Results: The Cronbach alpha is .93 for the total score, and test-retest reliability is r= .91. The principal components analysis revealed 6 factors explaining 50.24% of the variance. According to the structural equality model, fit indices indicate valid and reliable models. Analyses revealed significant correlation coefficients with NPI and BORRTI. Conclusion: The validity and reliability indicators of PNE Turkish form were within an acceptable range and PNE can be used for further studies.
