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.
