摘要

Objective:To investigate the relationship among childhood abuses,social support and non-suicidal self-injury (NSSI) in adolescents,and to examine the mediating effect of social support on the relationship between childhood abuses and non-suicidal self-injury.Methods:A total of 9704 middle school students were selected from junior and senior middle schools in Zhengzhou,Guiyang city.The Childhood Trauma Questionnaire-28 item Short Form (CTQ-SF),Non-Suicidal Self-Injury Questionnaire,Social Support Scale for University Students and Multidimensional Sub-health Questionnaire of Adolescents (MSQA) were used to measure the different types of adverse childhood experiences,non-suicidal self-injury,social support and psychopathological status.Results:The CTQ-SF-scores were positively correlated with non-suicidal self-injury scores (r =0.20,P ＜ 0.01) and negatively correlated with social support scores (r =-0.22,P ＜ 0.01).The total scores and factor scores of social supportscale were negatively correlated with non-suicidal self-injury scores in adolescents (P ＜ 0.01).When control of the area,grade,self-reported learning burden,self-reported grades and psychological pathology symptoms,social support in childhood abuse and the relation between the suicide self-injury the mediation effect by the single factor of 17.04％ to 12.57％,the mediation effect of three subcomponents accounted for 7.12％ ～ 13.85％.Conclusion:It suggests that social support may play a mediating effect on the relationship between childhood abuses and non-suicidal selfinjury.%目的:探讨青少年童年期虐待与非自杀性自伤的关系,以及社会支持在童年期虐待与非自杀性自伤关联中的中介效应.方法:采用分层整群抽样的方法,选取郑州、贵阳两地的9704名在校城乡初高中学生,采用儿童期虐待问卷(CTQ-SF)、青少年非自杀性自伤行为问卷、青少年社会支持量表(包括主观支持、客观支持、支持利用3个维度)、青少年亚健康多维评定问卷(MSQA)分别测量童年期虐待经历、非自杀性自伤、社会支持水平及心理病理症状.结果:CTQ-SF评分与青少年非自杀性自伤行为问卷得分呈正相关(r =0.20,P＜0.01),与青少年社会支持量表评分呈负相关(r=-0.22,P＜0.01);青少年社会支持量表及其各维度评分与青少年非自杀性自伤行为问卷得分呈负相关(均P＜0.01).控制户口所在地、自评学习负担、自评学习成绩和心理病理症状的影响后,社会支持在童年期虐待与非自杀性自伤关联中的中介效应占总效应的12.57％,3个维度的中介效应占总效应比例为7.12％ ～ 13.85％.结论:社会支持在童年期虐待与非自杀性自伤的关联中存在部分中介效应,良好的社会支持有助于有童年期虐待经历者自伤行为的预防和控制.
