中文摘要：

目的：探讨大学生累积的生活事件对其抑郁症状的影响,以及神经质是否对应激和抑郁之间的关系存在调节作用。方法：共有7399名在校大学生完成了学生日常社会和学业事件量表、儿童期虐待问卷、流调中心用抑郁量表,以及大五人格量表—神经质量表。通过皮尔逊相关分析、多重线性回归分析、分层回归分析等方法来分析应激对大学生抑郁的影响作用以及神经质的调节作用。结果：大学生经历的日常生活事件以及童年创伤事件对其抑郁程度都有显著的影响,而神经质会对应激和抑郁之间的关系起调节作用（△R-2=0.18）,神经质水平高的个体在应激状态下表现出更高的抑郁水平。结论：应激性事件会显著增加个体抑郁症状的严重程度,神经质调节了应激与抑郁症状之间的关系。

英文摘要：

Objective： To investigate the effect of stress on depressive symptoms in college students, and to examine whether neuroticism moderates the relationship between stress and depressive symptoms. Methods： A total of 7473 college students completed the General social and academic hassles scale（SHS）, Center for epidemiological studies depression scale （CESD）, Childhood maltreatment questionnaire（CTQ）, neuroticism measurement of the NEe personality inventory revised （NEO-PI-R）. Pearson correlation analysis, multiple linear regression analysis, and hierarchical regression analysis were used to analyze the impact of stress on depressive symptoms in college students and the moderating role of neuroticism. Results： The scores of SHS and CTQ had significant effect on the scores of CESD（both P〈0.001）, while neuroticism moderated the relationship between stress and depressive symptoms（△R^2=0.18）. Students with higher neuroticism reported more depressive symptoms than other university students. Conclusion： Stressful life events might significantly affect the severity of depressive symptoms, while neuroticism moderates the relationship between stress and depressive symptoms.
