The universality and sufficiency of the five-factor model in the Chinese co
ntext were investigated. In Study 1, analysis of the Revised NEO Personalit
y Inventory (NEO-PI-R) and the Chinese Personality Assessment Inventory (CP
AI) taken by Chinese students showed four joint factors similar to the doma
ins of the NEO-PI-R. Two unique factors were obtained. The Interpersonal Re
latedness factor was defined only by CPAI scales. The Openness domain, howe
ver, was not represented in the CPAI scales. In Study 2, involving Chinese
managers, the robustness of the Interpersonal Relatedness factor was demons
trated. In Study 3, the six-factor model was confirmed with Hawaiian studen
ts. Further analyses showed that the six-factor models were superior to the
Five-factor models and that the Interpersonal Relatedness scales could not
be consistently explained by a combination of the Big Five factors. Implic
ations for the universality of the five-factor model and the cross-cultural
relevance of the CPAI Interpersonal Relatedness factor are discussed.
