The ways of the world? Cross-sample replicability of personality trait-life outcome associations

Research in (mostly) Western samples has indicated that personality domains' associations with life outcomes are replicable but often driven by their facets or nuances. Using three diverse samples (English-speaking, N=1,232; Russian-Speaking, N=1,604; Mandarin-speaking, N=1,216), we compared personality trait-outcome associations at domain, facet, and nuance levels, both within and among samples. Trait-outcome associations were at least moderately consistent among samples for all trait-hierarchy levels (average intraclass correlations = 0.64 to 0.74). Nuances provided the strongest predictive accuracy, both within and among samples. Trait-outcome associations were higher among English-speakers than Mandarin and Russian-speakers. Our observations suggested moderate generalizability among diverse samples, with nuances providing unique and replicable information. This offers potential to improve understanding of trait-outcome patterns.
