The Short Form of the Five-Factor Narcissism Inventory: Psychometric Equivalence of the Turkish Version

Abstract

This study intends to examine the psychometric properties of the Turkish version of the short form of the Five-Factor Narcissism Inventory (FFNI-SF). The study group consists of a total of 526 university students (54% were female) whose ages range from 18 to 32. In the translational equivalence study made over a two-week interval, the FFNI-SF scores showed high consistency. Cronbach’s alpha was found to be .87 for the total score, and the alphas for the FFNI-SF subscales ranged from .57 to .79. Corrected item-subscale correlations for the items ranged from .22 to .73. Confirmatory factor analysis results have shown that among the three competing models derived from the conceptual models, Model 1 with 15 factors had the best goodness-of-fit to the data, ? ² = 3851.48, df = 1605, ? ²/sd = 2.40, RMSEA = .057, AGFI = .74, GFI = .77, CFI = .77, NNFI = .75. The correlation of total scores from the Narcissistic Personality Inventory (NPI) and FFNI-SF was .65, p < .01. Study results indicated that the Turkish version of the FFNI-SF may serve as a useful tool in assessing narcissistic personality traits in non-clinical samples.
