Translation and validation of the BFI-2 in a Croatian sample

Abstract

This paper describes the process of translation and validation of the adaptation of the Big Five Inventory-2 (BFI-2) in the Croatian language. The translation process from English to Croatian was conducted using a forward and backward translation process. The resulting adaptation was then assessed for structural and construct validity, as well as reliability on a convenience sample of 320 Croatian participants. The results showed good reliability estimates at the domain level and somewhat lower yet satisfying estimates at the facet level. Confirmatory factor analyses (CFAs) supported the proposed hierarchical structure. The BFI-2 domains and facets showed adequate construct validity, estimated via the within- and between-domain correlations of the facet scales. Overall, the preliminary results of the Croatian adaptation are satisfactory and support efforts for further improvement and assessment in a larger sample, adequate for research in personality psychology.
