The HEXACO Adjective Scale: A Cross-Cultural Validity Study

Area of Science:

• Psychology
• Cross-cultural Psychology
• Personality Assessment

Background:

• The HEXACO model is a robust framework for understanding personality across six dimensions.
• The HEXACO Adjective Scale (HAS) was initially developed in Italian.
• Cross-cultural validation is crucial for personality measures.

Purpose of the Study:

• To assess the cross-cultural validity and measurement invariance of the HEXACO Adjective Scale (HAS).
• To evaluate the psychometric properties of translated HAS versions in French, Dutch, and English.

Main Methods:

• Translation of the Italian HAS into French, Dutch, and English.
• Administration of translated scales to participants in Belgium (Dutch), France (French), and the US (English).
• Confirmatory Factor Analyses (CFAs) to assess structural validity and measurement invariance.

Main Results:

• CFAs confirmed the original HEXACO structure across all translated languages.
• Strong evidence of measurement invariance was found across French, Dutch, and English versions.
• The translated HAS scales demonstrated satisfactory internal consistency and predictive validity for behavioral criteria.

Conclusions:

• The HEXACO Adjective Scale (HAS) exhibits strong psychometric properties and cross-cultural validity.
• The findings support the replicability of the HEXACO model across different cultures and languages.
• The translated HAS is suitable for future cross-cultural personality research.
