The Affective Style Questionnaire is a self-report instrument for assessing affective style. Study 1 investigated the psychometric properties of the Chinese Affective Style Questionnaire in a sample of 459 Chinese participants. The confirmatory factor analysis supported a three-factor structure. Study 1 indicated that the Chinese Affective Style Questionnaire can be used as a simple, reliable, and valid scale for measuring individual differences in affective style. Study 2 examined the moderating role of different affective styles in the relationship between stress and negative affect. Concealing and tolerating moderated the relationship between stress and anxiety, and adjusting moderated the relationship between stress and depression.
