Results: The exploratory factor analysis results showed that item factor loadings of ERQ were between .53 and .75. Item-total correlations were above the .33. All items were determined by separate groups within the upper and lower levels of emotion regulation. The confirmatory factor analysis results showed that the original version of the ERQ confirmed on the Turkish version. Internal consistency coefficients of the scale were found .78 for cognitive reappraisal, .71 for suppression, and .72 for total. Test-retest results loaded above .65.
