The Effect of Stressful Life Events on College Students’ Depression: A Moderated Mediating Model

A questionnaire survey was conducted among 1659 college students to investigate the mediating role of loneliness between stressful life events and college students’ depression, at the same time, the moderating effect of perceived organizational support on the mediating mechanism was tested. The results show that: (1) there is a positive correlation between stressful life events and depression; (2) stress life events also indirectly affect college students’ depression through the mediating effect of loneliness; (3) perceived organizational support plays a moderating role between stressful life events and loneliness. With the increase of perceived organizational support, the positive predictive effect of stressful life events on loneliness is weakened; (4) perceived organizational support further moderates the mediating role of loneliness between stressful life events and college students’ depression. The results of the study have a certain guiding role in enriching the related research of College Students’ stress and depression, as well as the prevention and intervention of College Students’ stress and depression.
