The effect of problem focused coping (PFC) on meta-cognition as well as the effect of emotion focused coping (EFC) on working memory was strongly significant. Decision making was an executive function that independently influenced on MDD. Our overall results represented that the main executive functions that strongly influenced the correlation between coping with stress styles and MDD were meta-cognition, working memory and decision making respectively.
