Further Validation of Slovak Big Five Inventory–2: Six-Months Test-Retest Stability and Predictive Power

Abstract

The current study focuses on exploring the 6-month test-retest stability of the Slovak second version of the Big Five Inventory (BFI-2) and its predictive power for subjective and psychological well-being, on value-focused behavior and everyday behavior. The sample consisted of 414 adult Slovak participants, who reported on their personalities using the BFI-2 on the first occasion, and then again circa 6 months later, along with well-being and behavior self-report measures focused on the past 6 months. The results showed a 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–behavior 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.
