Empirical overlap and predictive validity of Big Five and HEXACO personality models

In the field of personality research, there has long been a consensus that personality structure is best captured with five broad factors. However, another model, HEXACO with six factors, is increasingly used. We aimed to in-vestigate the overlap between those personality models, as well as their predictive validity for relevant outcomes. A total of 132 psychology students (81.8% women, Mage = 23.33, SD = 1.31) filled in HEXACO-60, BFI, Subjective Happiness Scale and reported their grade-point average (sGPA). Results of 11 multiple regression analyses, in which five BFI scales predicted each of the six HEXACO-60 scales and vice versa, showed that BFI scales do not capture variance of HEXACO Honesty-Humility (R2adj = .08) and Emotionality (R2adj = .36) factors well. Regard-ing predictive validity, both BFI and HEXACO significantly predicted variance of subjective happiness, but BFI explained the larger amount than HEXACO, while only BFI scales captured a significant amount of sGPA variance. Therefore, findings of this study suggest that BFI scales do not capture all HEXACO variance well, but the results of the predictive validity comparison indicate that we cannot definitively conclude that one model is better than the other.
