Further validation of Slovak Big Five Inventory 2: 6-months test-retest stability and predictive power

Abstract

The current study focuses on exploring the 6-month test-retest stability of Slovak second version of the Big Five Inventory (BFI-2) and its predictive power for subjective and psychological well-being, on value-focused behaviour and everyday behaviour. The sample consisted of 414 adult Slovak participants who reported their personalities using the BFI-2 on the first occasion and then again after circa 6 months along with well-being and behaviour self-report measures focused on the past 6 months. The results showed strong test-retest stability of the Slovak BFI-2’s domains and facets. The Slovak BFI-2 also showed the expected pattern of well-being predictions with Extraversion and Negative Emotionality domains as the strongest predictors. Furthermore, meaningful trait–behaviour links of the Slovak BFI-2 were discovered. Overall, our results contribute to the robust international knowledge base regarding stability, predictive power and ecological validity of the Big Five personality factors.
