Cross-sectional age differences in the HEXACO personality: Results from a Japanese sample

Little research has been conducted on personality development in non-Western countries. The present study investigated age differences in personality in Japanese middle adults (N = 2000; M = 40.94 years; SD = 5.35, range 30–49; 1000 women). After controlling for educational level, annual income, marital status, and gender, it was found that the level of Emotionality was negatively associated with age. Honesty–Humility, on the other hand, was positively associated with age. However, Extraversion, Agreeableness, Conscientiousness, and Openness were not associated with the participant age. These findings suggest that trends in personality development may differ slightly between Western and non-Western countries.
