Психометрика русскоязычной версии Big Five Inventory–2
The present article aims to assess psychometric characteristics of the Russian version of the Big Five Inventory-2 (BFI-2). This questionnaire measures five basic personality traits, as well as three facets for each trait. The data were collected online, with a total sample of 1,787 people (31.9% of men) aged from 14 to 54 years (M = 26.31; SD = 7.76). The study covered more than ten regions of the Russian Federation. The factorial structure of the BFI-2 was examined using the principal component analysis, confirmatory factor analysis and random intercept exploratory factor analysis. The five-factor structure of the BFI-2 was confirmed both at the trait and facet levels. The analysis of measurement invariance revealed that the Russian BFI-2 demonstrates strict equivalence across sex, which makes it possible to compare raw scores of the questionnaire when assessing sex differences. The results on sex differences obtained in this study were consistent with the extant findings published in the literature. Across various BFI-2’s subscales, internal consistency measured by the Cronbach’s alpha and McDonald’s omega was satisfactory, good, or excellent. A scale discrimination test (Ferguson’s delta in the adaptation by M. Hankins) was high which shows the questionnaire's capability to distinguish individuals with various manifestations of a domain or facet. Therefore, the Russian version of the BFI-2 is a reliable and valid tool for measuring the basic traits and facets of personality.
