Assessing Dimensions of Pathological Narcissism: Psychometric Properties of the Short Form of the Five-Factor Narcissism Inventory in a Sample of Italian University Students

ABSTRACT

To evaluate the psychometric properties of the Italian translation of the Five-Factor Narcissism Inventory–Short Form (FFNI–SF), 1,063 Italian university students were administered the scale, along with the Pathological Narcissism Inventory (PNI) and the Measure of Disordered Personality Functioning (MDPF). In general, the FFNI–SF scales showed good internal consistency (median α = .76; median interitem r = .44) and structural analyses suggested a 3-component model of FFNI–SF scales that was similar to that reported by Sherman et al. (2015). FFNI–SF second-order scales yielded meaningful convergent and discriminant correlations with PNI second-order grandiose and vulnerable dimensions. Finally, FFNI–SF second-order scales correlated in expected ways with 2 dimensions of personality dysfunction.
