The main purpose of this study is to adapt the Affective Style Questionnaire (ASQ) into Turkish. It also aims to examine the mediating role of affective styles between attachment styles and depression. The study was conducted on a total of three different samples (N1 = 261; N2 = 190; N3 = 263). The confirmatory factor analysis (CFA) was used to test the construct validity of the scale and the Emotion Regulation Questionnaire (ERQ) was used to test the convergent validity. As a result of the CFA conducted in all three samples, the model was found to have adequate fit values. In the convergent validity, ASQ were found to be significantly correlated with ERQ. The findings indicate that adjusting mediated between secure attachment and depression while concealing mediated between avoidant attachment and depression, and adjusting and concealing mediated between anxious-ambivalent attachment and depression. The findings were also discussed in light of the related literature.
