This study investigates the usefulness of morningness-eveningness and emotion dysregulation for better understanding of social anxiety dimensions. Specifically, associations between morningness-eveningness and incremental validity of emotion dysregulation as a predictor of social anxiety were examined. Data were obtained from a sample of normal students (N=510). Results of regression analyses showed that morningness was a significant predictor of social anxiety variables. Dimensions of emotion dysregulation had multiple associations with facets from social anxiety. Emotion dysregulation was found to be a positive predictor of social anxiety. The results expand the understanding of social anxiety and indicate how the domains of morningness-eveningness and emotion regulation could explain social anxiety in a normal population.
