This study examined the frequencies and effects of three kinds of interpersonal stress coping (positive relationship-oriented, negative relationship-oriented, and postponed-solution coping) with each of the three types of interpersonal stressors in friendships (interpersonal conflict, interpersonal blunders, and interpersonal friction) on mental health and subjective well-being. Participants were 951 college students. Positive relationship-oriented coping was used most frequently in interpersonal blunders; negative relationship-oriented coping was used most often in interpersonal conflict; and postponed-solution coping was used least frequently in interpersonal blunders. The associations between each type of interpersonal stress coping and each dependent variable (depression, loneliness, and relationship satisfaction) were almost constant across the three interpersonal stressors.
