儿童期虐待对生命意义感的影响:一个有调节的中介模型

Impact of childhood abuse on the meaning of life:A moderated mediation model

目的:为探究儿童期虐待对生命意义感的影响,并探讨消极自我图式的中介作用和回避性特质的调节作用。方法:采用儿童期虐待量表、简明核心图式量表、特质焦虑量表、特质抑郁量表和生命意义感量表对某大学抽样的750名大学生进行问卷调查,最终回收有效问卷695份。结果:儿童期虐待显著负向预测生命意义感(β=-0.142,t=-3.738,P<0.001);中介效应分析结果表明,消极自我图式在儿童期虐待与生命意义感之间起中介作用(β=-0.2803,95%的置信区间为[-0.354,-0.210]),中介效应量为-0.0907,中介效应且占总效应的48.95%。有调节的中介模型检验表明,“儿童期虐待-消极自我图式-生命意义感”这一中介效应的前半路径受到回避性特质的正向调节(R=0.106,F=20.455,P<0.001)。结论:儿童期虐待对生命意义感既存在直接影响,又存在通过消极自我图式对其的间接影响,而回避性特质调节了前述中介效应的前半段路径,即儿童期虐待与消极自我图式的关系受回避性特质的调节。

Objective:To explore the impact of childhood abuse on the sense of meaning in life,and to explore the mediating role of negative-self-schema and the moderating role of avoidance traits.Methods:Using the Childhood Trauma Scale,Brief Core Schema Scale,Trait Anxiety Scale,Trait Depression Scale,and Sense of Life Scale to conduct a questionnaire survey on 750 college students sampled from a university,and finally 695 valid questionnaires were collected.Results:Childhood abuse significantly negatively predicted the meaning of life(β=-0.142,t=-3.738,P<0.001);The mediating effect analysis results showed that the negative-self-schema played a mediating role between childhood abuse and the sense of life meaning(β=-0.2803,95%confidence interval was[-0.354,-0.210]),the mediating effect was-0.0907,and the mediating effect accounted for 48.95%of the total effect.The test of the regulated mediation model showed that the first half of the mediating effect of"childhood abuse-negative-self-schema-meaning of life"was negatively regulated by avoidance traits(R~2=0.106,F=20.455,P<0.001).Conclusion:Childhood abuse has both a direct impact on the sense of meaning of life and an indirect impact on it through negative-self-schema.The avoidance trait modulates the first half of the aforementioned mediating effect,namely childhood abuse and negative-self-schema.The relationship is regulated by avoidance traits.
