Slovak Adaptation of the Big Five Inventory (BFI-2): Psychometric Properties and Initial Validation

Keywords: BFI-2, Big Five personality traits, psychometric adaptation

Abstract

The article describes the process of adaptation of the Big Five Inventory – 2 into the Slovak language and cultural context. The translation process of the Slovak BFI-2 was based on three data samples using item analysis and basic psychometric properties. The present study estimates the psychometric properties of the Slovak BFI-2 and its hierarchical structure using exploratory and confirmatory factor analysis in an independent sample of 526 participants recruited through an online research panel. It also provides data on convergent-discriminant validity in relation to alternative Big Five measures (NEO-FFI, TIPI) and to standard well-being measures. The results showed good internal consistency on the domain level, and somewhat lower on the facet level. Both exploratory and confirmatory factor analyses successfully recovered the conceptual structure of the Slovak BFI-2. The BFI-2 domains and facets showed adequate convergent-discriminant validity, based on the meaningful pattern of correlations with the other Big Five measures and well-being scales. These findings suggest that the Slovak version of the BFI-2 is a reliable and valid measure of the Big Five personality traits, and is appropriate for use in Slovak and cross-cultural research.
