The universality and sufficiency of the five-factor model in the Chinese context were investigated. In Study 1, analysis of the Revised NEO Personality Inventory (NEO-PI-R) and the Chinese Personality Assessment Inventory (CPAI) taken by Chinese students showed four joint factors similar to the domains othe NEO-PI-R. Two unique factors were obtained. The Interpersonal Relatedness factor was defined only by CPAI scales. The Openness domain, however, was not represented in the CPAI scales. In Study 2, involving Chinese managers, the robustness of the Interpersonal Relatedness factor was demonstrated. In Study 3, the six-factor model was confirmed with Hawaiian students. 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. Implications for the universality of the five-facto model and the cross-cultural relevance of the CPAI Interpersonal Relatedness factor are discussed.
