This study tested a model that links stress, social support, problem-focused coping, and well-being. First, it looks at how high support significantly moderated the association between stress and well-being. Next, the students' problem-focused coping was seen as mediating this moderated association. Finally, a 3-way interaction of stress, social support, and avoidant coping revealed that only frequent use of avoidant coping accelerated the association between stress and well-being in a negative way at both low and high support.
