自尊在农村中学生行为与暴力遭遇间的中介效应

Behavior and Exposure to Violence:Mediating Role of Self-esteem in Rural Middle School Students

目的:探讨自尊在农村中学生行为与暴力遭遇间的中介效应。方法:本研究采用横断面研究方法,对3620名随机选择的农村中学生进行问卷调查。暴力遭遇采用WHO暴力遭遇调查问卷,行为问题评定采用Achenbach儿童行为自陈量表(CBCL),自尊水平的评价采用Rosenberg自评量表。结果:在以暴力遭遇为应变量的多元线性回归方程中,加入自尊(中介变量),减少行为与暴力遭遇(β从0.232到0.226)之间的联系强度;Sobel检验证实:自尊在行为与暴力遭遇之间起部分中介效应(β从0.232到0.226,Sobel-Zvalue=2.340,P=0.019);采用同样的模型,分别对言语、躯体和性暴力进行分析,结果表明:自尊(中介变量)在行为与言语暴力之间起部分中介效应(β从0.225到0.200,Sobel-Z value=1.992,P=0.046);而自尊在行为与躯体暴力或性暴力之间无中介效应。结论:自尊在农村中学生行为与暴力遭遇(尤其是言语暴力)之间起部分中介效应。

Objective： To test a model in which serf-esteem mediated the effects of behavior on exposure to violence （victimization） in a sample of rural middle school students. Methods： A cross-section study was conducted in 3620 middle school students randomly selected from rural areas. A questionnaire of violence （WHO） and Achenbach Children Behavior Checklist （CBCL） and Rosenberg serf-esteem scale were used to measure the exposure to violence behavior, and serf-esteem respectively. Results： Hierarchical regression analyses provided evidence that the addition of serf-esteem reduced the links between behavior and exposure to violence （β from 0.232 to 0.226）. Sobel Z-test predicted that serf-esteem partially mediated the effects of behavior on exposure to violence （victimization） with significant difference （β from 0.232 to 0.226, Sobel-Z value=2.340, P=0.019）. Speech violence, physical violence, and sexual violence were tested by the same model respectively, and the results showed that serf-esteem partially mediated the effects of behavior on speech violence with significant difference （β from 0.225 to 0.200,Sobel-Z value=1.992,P=-0.046）, but not on physical or sexual violence. Conclusion： Serf-esteem partially mediates the effects of behavior on exposure to violence （emotion violence）.
