This study aimed to preliminarily assess the cross-cultural applicability and validity of the HEXACO personality inventory. The researchers utilized a literature analysis method, retrieving 460 related studies, and finally selected 10 studies in different languages analyzing reliability and validity. Results indicated that the HEXACO inventory demonstrated good internal consistency reliability (.64-.92) when applied in different countries, despite some fluctuations due to varied test length. The six-factor structure of HEXACO was supported through exploratory factor analysis, with explained variance between 44.1% and 58.4%. The factors showed discriminant validity and moderate to high correlations with Extraversion, Conscientiousness, Openness and Agreeableness in the Big Five model. Notably, the unique sixth factor of HEXACO, ""Honesty-Humility,"" captured aspects not included in the Big Five model. In summary, the HEXACO scale has cross-cultural applicability, but some of the translated questions need to be revised. Among the four versions, HEXOCA-PI-R or HEXACO-100 can be given priority. It is recommended that counseling practitioners could use the HEXOCA scale to evaluate clients as a basis for case conceptualization and intervention. In the future, it is recommended to continue to conduct research on Chinese people as a bridge for dialogue between cross-cultural personality theory and localized personality theory.
