摘　　要：目的:探讨医学生抑郁与非自杀性自伤(NSSI)行为的关系以及社会支持在医学生抑郁与NSSI行为之间的中介作用。方法:以广西医科大学为研究现场,采用自编一般情况调查表、渥太华自伤量表(OSI)、流调用抑郁自评量表(CESD)以及领悟社会支持量表(PSSS)对859名在校学生进行问卷调查。结果:广西医科大学医学生NSSI检出率为15.13%(130/859)。CESD评分与NSSI判断条目得分呈正相关关系(r=0.43,P<0.01),与PSSS评分呈负相关关系(r=-0.52,P<0.01);PSSS评分及其3个维度(朋友支持、家庭支持、其他支持)评分和NSSI判断条目得分均呈负相关关系(r=-0.33、-0.27、-0.31、-0.33,均P<0.01);医学生的社会支持在抑郁与NSSI行为之间起部分中介作用,中介效应比例为18.75%。结论:抑郁可能会促使医学生NSSI行为的发生,但这一过程可通过社会支持中介变量起缓冲作用,良好的社会支持有助于降低有抑郁问题的医学生发生NSSI行为的风险。Objective:To explore the relationship between depression and non-suicidal self-injury(NSSI)and the mediating effect of social support between depression and NSSI among medical students.Methods:Guangxi Medical University was selected as the research site,and a total of 859 medical students were recruited in the study to complete the self-designed General Situation Questionnaire,Ottawa Self-injury Inventory(OSI),Center for Epidemiologic Studies Depression Scale(CESD)and Perceived Social Support Scale(PSSS).Results:The detection rate of NSSI among medical students of Guangxi Medical universities was 15.13%(130/859).The CESD scores were positively correlated with NSSI scores(r=0.425,P<0.01)and negatively correlated with PSSS scores(r=-0.524,P<0.01).The PSSS scores and the three dimensions(friend support,family support and other support)scores were negatively correlated with NSSI scores(r=-0.33,-0.27,-0.31 and-0.33,all P<0.01).Social support played a partial role in mediating the relationship between depression and NSSI among medical students.The proportion of mediating effect was 18.75%.Conclusion:Depression may drive the occurrence of NSSI among medical students,but this process can be buffered by mediating variables of social support.Good social support can help reduce the risk of NSSI among medical students with depression problems.
