Abstract: Objective To explore the mediating effect of social support in the relationship between childhood ignore and the vocational students' self-injury,and provide theory support for study secondary vocational students' self-injury. Methods Totally 814 secondary vocational students from five vocational schools in Liaoning province were assessed with the Childhood Neglect Scale,Juvenile Self-injured Scale and Juvenile Social Support Scale.The regression analysis was used to test the mediating effect of social support between childhood ignore and secondary vocational students' self-injury. Results The relationship between social support and self-injury/childhood neglect was significantly negative correlated (r=-0.10~-0.26,all P<0.01),and the relationship between self-injury and childhood neglect was significantly positively correlated(r=0.24~0.28,all P<0.01).The childhood neglect was positively associated with secondary vocational students' self-injury (β=-0.43,P<0.01).In addition,social support mediated the relationship between childhood neglect and self-injury,the value of mediating effect was 6.82%. Conclusion Social support plays a mediating role between childhood neglect and self-injury.

摘要： 目的 通过研究儿童期受忽视、社会支持与中职生自伤行为的中介作用,为中职生自伤行为的研究提供理论依据。方法 选取辽宁省5所中职院校的学生814名。采用童年期被忽视问卷、青少年自伤行为问卷和青少年社会支持问卷进行测量。使用回归分析检验社会支持在童年期受忽视与自伤行为之间的中介作用进行检验。结果 社会支持与童年期受忽视、自伤行为呈显著负相关(r=-0.10~-0.26,P均<0.01),而与自伤行为得分呈显著正相关(r=0.24~0.28,P均<0.01)。儿童期受忽视对自伤行为有正向预测作用(β=0.43,P<0.01);社会支持在儿童期受忽视与自伤行为间具有部分中介效应,中介效应占总效应的6.82%。结论 社会支持在儿童期受忽视与中职生自伤行为间具有中介作用。
