初中留守儿童歧视知觉对问题行为的影响——基于自尊和社会支持的链式中介作用

The Influence of Discrimination Perception of Left behind Children in Junior High School on the Problem Behavior:the Chain Mediating Effect of Self Esteem and Social Support

为探究歧视知觉对留守儿童问题行为的影响,以及自尊和社会支持可能产生的中介作用,研究采用留守儿童歧视知觉问卷和青少年问题行为调查问卷,对云南省182名中学生进行调查,并运用结构方程模型探讨了歧视知觉对问题行为影响的内在机制。研究发现,歧视知觉影响社会支持的路径系数为-0.35,社会支持影响问题行为的路径系数为-0.47,歧视知觉影响自尊的路径系数为-0.29,自尊影响社会支持的路径系数为0.45,各路径系数均达到显著水平(p<0.01)。结果表明:1)歧视知觉通过社会支持的中介作用影响问题行为;2)歧视知觉通过自尊和社会支持的链式中介作用影响问题行为。

The study used left-behind children＇s perceived discrimination questionnaire and adolescent problem behavior questionnaire to investigate left-behind children in middle school students of Yunnan Province, and applied the structural equation model to probed into the inherent mechanism of effects of perceived discrimination on behavior problems. It were found that discrimination affected the perceived social support of path coeffcient was -0.35, social support behavioral impact of path coeffcient was -0.47, path coeffcient of perceived discrimination on self-esteem was -0.29, self-esteem affect social support path coeffcient was 0.45. The path coeffcient reached signifcant level （P 〈 0.01）. The results showed that the infuence from discrimination perception to problem behavior has the following two paths： （1） the problem behavior was infuenced by the mediating effect of perceived social support; （2） the problem behavior was infuenced by the chain mediating effect of self-esteem and social support.
