Abstract Objective To explore the effects of clinical medical undergraduates’ perceived stress on depression, and analyze the roles of psychological capital and perceived social support. Methods A total of 743 clinical medical undergraduates were selected. They were assessed with perceived social support scale(PSSS), Chinese perceived stress scale(CPSS), psychological captial questionnaire(PCQ), and the center for epidemiologic studies depression scale(CES-D). Results Pearson correlation analysis showed that perception stress was significantly positively correlated with depression, and negatively correlated with perceived social support and psychological capital. Psychological capital played partial mediating role between perceived stress and depression. Perceived social support not only moderated the relationships between perceived stress and depression, but also moderated the relationships between perceived stress and psychological capital. Conclusion The results suggest that the relations between perceived stress and depression may be mediated by psychological capital, and regulated by perceived social support.
