Affective style is an individual difference variable that refers to tendencies for regulating emotions. The emotion research literature has consistently identified three general strategies to handle emotional reactions: some strategies are aimed at re-adjusting affect to adapt successfully to situational demands; other strategies are intended to conceal or suppress affect; and a third approach is to tolerate and accept emotions, including unwanted and aversive reactions. We conducted two studies to develop a self-report measure to assess these affective styles. In the first study (n = 434), a list of 127 items related to this construct was administered. A factor analysis supported three factors: habitual attempts to conceal or suppress affect (Concealing subscale; 8 items), a general ability to manage, adjust, and work with emotions as needed (Adjusting subscale; 7 items), and an accepting and tolerant attitude toward emotions (Tolerating subscale; 5 items). The scale showed satisfactory internal consistency. Furthermore, the respective subscales showed different patterns of relations with existing instruments measuring similar constructs. Findings were cross-validated in an independent sample (n = 495). The factor structure and results of psychometric analyses were replicated. The final 20-item Affective Style Questionnaire is a brief instrument to measure individual differences in emotion regulation.
