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.
