The BFI-2 (Soto & John, 2017) has been adapted to various languages and cultures, but not yet to a Swedish context. Its predictive power has been investigated mainly on domain level, but to a lesser extent on facet level. In three large samples, N = 824, N = 1,104, and N = 823, using an online questionnaire, the intended five-factor structure for the domains Extraversion, Agreeableness, Conscientiousness, Negative Emotionality, and Open-Mindedness was reproduced in all three samples, both based on items and the facet scores. Reliability was good for the domains, more diverse for the facets, but still acceptable in most cases. Invariance analyses revealed high correspondence with the American original. The predictive validity was evaluated for individual (psychological well-being), interindividual (attachment styles), and intergroup (social dominance orientation and ambivalent sexism) variables. Regression analyses revealed significant and theoretically meaningful patterns, both for the domains and their facets.
