Investigating the structure of the Polish Five Factor Narcissism Inventory: Support for the three-factor model of narcissism.

The 3-factor model of narcissism is generally agreed upon within the literature. However, only a limited number of studies have investigated its structure. We investigated the internal structure of the measure using exploratory factor analysis on the Polish adaptation of the Five Factor Narcissism Inventory (FFNI). This article reports results of 2 studies conducted in Poland, including a total of 793 adults. The results of both studies provided evidence for the 3-factor structure of narcissism. Nevertheless, there were also some deviations: Grandiose fantasies, thrill seeking and arrogance do not load appropriately on any factor, and manipulativeness and reactive anger were better indicators of agentic extraversion and narcissistic neuroticism than self-centered antagonism. The validity of the modification of the FFNI scoring was assessed in regard to the Big Five personality traits and other measures of narcissistic personality. Results provide evidence that the composite scores of the 3 factors are valid and that the modification of scoring improves the measurement precision of the FFNI.
