Abstract：To explore the influencing and protective factors of depression among college students and identify
the mediating pathways of negative life events，social support，and psychological resilience on depression，this
study conducted a questionnaire survey on 633 college students using psychological scales and tested the
proposed hypotheses using a moderated mediation model. The findings revealed that，① overall，depression
among current college students is within a manageable range. ② Negative life events，social support，and
psychological resilience were significantly correlated with depression. ③Negative life events positively predicted
depression while social support partially mediated this relationship（effect size=0.069，P<0.01）. ④ Psychological
resilience significantly moderated the effect of negative life events on depression （β =0.093，P<0.01）. These
findings validate the applicability of the Diathesis ⁃ Stress Model and Buffer Theory of Social Support among
college students，revealing that negative life events indirectly exacerbate depression by weakening social support，
while psychological resilience strengthens the protective effect of social support. Higher education institutions
should prioritize cultivating students’psychological coping capacities，providing effective social support，and
addressing the needs of students with moderate to severe depression through targeted intervention and counseling.
