领悟社会支持在儿童期虐待与自杀行为的中介作用

Mediating effect of perceived social support between childhood abuse and suicide risk

目的探索领悟社会支持在童年期虐待与自杀行为之间的中介作用,以及这三者的关系。方法采用儿童期虐待问卷、自杀行为问卷、领悟社会支持量表调查1 880名在校医学生。结果领悟社会支持、自杀行为和童年期虐待的平均得分分别为(69.73±10.66)、(4.03±1.71)和(39.93±8.63);领悟社会支持与儿童期虐待呈显著负相关(r=-0.278,P<0.01),与自杀风险也呈显著负相关(r=-0.489,P<0.01),儿童期虐待与自杀风险呈显著正相关(r=0.423,P<0.01);童年虐待、领悟社会支持对自杀风险的回归方程t检验显著,领悟社会支持的中介效应显著,中介效应占总效应的比例为10.8%。结论儿童期虐待、领悟社会支持和自杀行为的相关密切,领悟社会支持在童年虐待和自杀风险之间起着部分中介效应。

Objective To explore the mediating effect of perceived social support between childhood abuse and suicide risk,and their relationship.Method 1 880 medical students were investigated by childhood abuse questionnaire,suicidal behaviors questionnaire-revised,and perceived social support scale.Results The average score of perceived social support scale was(69.73±10.66),the average score of suicidal behaviors questionnaire-revised was(4.03±1.71),and the score of childhood abuse questionnaire was(39.93±8.63).There was a significant negative correlation between childhood abuse and perceived social support(r=-0.278,P<0.01),a significant negative correlation between suicide risk and perceived social support(r=-0.489,P<0.01),and a significant positive correlation between childhood abuse and suicide risk(r=0.423,P<0.01).The mediating effect of perceived social support was significant,the proportion of mediating effect was 10.8% in total effect.Conclusion Child abuse,perceived social support,and suicidal behaviors are closely related,and perceived social support plays a part of intermediary effect between childhood abuse and suicidal risk.
