We investigated the reliability of the HEXACO ‐Personality Inventory ( HEXACO‐PI ) using the NEO F ive‐ F actor Inventory ( NEO‐FFI) and the I nternational P ersonality I tem P ool ( IPIP) B ig F ive scales in a J apanese sample of 492 respondents (mean age = 20.4 years). The psychometric properties of the HEXACO‐PI were examined and found to be satisfactory. The results of the factor analysis showed that the six hypothesized personality domains were found independently. A total of 307 participants responded to the NEO‐FFI and the IPIP B ig F ive scales. The results showed that the five domains of the HEXACO model corresponded to the F ive‐ F actor domains and were relative to the B ig F ive personality domains as a whole, but the sixth domain, H onesty‐ H umility, showed weak to moderate correlations with some factors of the NEO‐FFI and the IPIP B ig F ive scales. These results suggest that the H onesty‐ H umility domain is independent of the five fundamental personality factors and that the HEXACO‐PI is a useful and reliable questionnaire for investigating personality structure in cross‐cultural and other context.
