以往研究发现儿童对父母冲突的评价会影响其生活质量，但对于父母冲突评价如何影响儿童主观幸福感，以及二者之间具有危害或保护作用的因素还有待进一步探讨。本研究在认知-背景理论的指导下，构建了一个有调节的中介模型，检验负性自动思维在父母冲突评价和儿童主观幸福感之间的中介作用、以及祖孙关系在负性自动思维的调节作用。

本研究采用父母冲突评价问卷、儿童自动思维问卷、主观幸福感问卷和祖孙关系问卷对北京市228名儿童进行调查，结果表明：

（1）在控制了年龄和性别后，父母冲突评价对儿童主观幸福感并无直接预测作用。

（2）中介效应检验表明，负性自动思维在父母冲突评价和儿童主观幸福感之间起到完全中介作用。

（3）有调节的中介模型进一步表明，祖孙关系亲密对“父母冲突评价→负性自动思维→儿童主观幸福感”的前半段具有调节作用，即当祖孙关系越亲密，父母冲突评价对儿童负性自动思维的预测作用越强。祖孙亲密度降低时，父母冲突评价对儿童负性自动思维的预测作用减小。

   本研究的结果表明，父母冲突评价主要通过儿童负性自动思维来减少儿童的主观幸福感，并且祖孙关系在其中起到调节作用。本研究结果验证了父母冲突的认知-背景理论，并且启示学校可以通过开设团体辅导课程来增加孩子的幸福感，同时对父母如何减少冲突对孩子的影响具有指导意义。

Previous studies have found that children's assessment of parental conflict can affect their quality of life, but how the assessment of parental conflict affects children's subjective well-being and the factors that may harm or protect them remains to be further explored. Under the guidance of cognitive-background theory, a moderated mediation model was constructed to test the mediating effect of automatic thinking on the evaluation of parental conflict and children's subjective well-being, as well as the moderating effect of grand-grandchild relationship on the first half of the path. In this study, 228 children in Beijing were investigated by using the questionnaire of evaluation of parental conflict, the questionnaire of children's automatic thinking, the questionnaire of subjective well-being and the questionnaire of grand-grandson relationship. The structural equation model analysis shows that:

(1) after controlling for age and gender, parental conflict assessment does not directly predict children's subjective well-being. The mediating effect test shows that automatic thinking plays a completely mediating role between the evaluation of parental conflict and children's subjective well-being.

(2) the moderated mediation model further shows that grand-grandson relationship intimacy has a moderating effect on the first half of "parental conflict evaluation → automatic thinking → children's subjective well-being", that is, the closer the grand-grandson relationship is, the stronger the prediction effect of parental conflict evaluation on children's automatic thinking is.

The results of this study show that the evaluation of parental conflict mainly reduces children's subjective well-being through automatic thinking, and the grand-grandchild relationship plays a catalytic role in it.

The results of this study verify the cognitive-background theory of parental conflict, and suggest that schools can increase children's happiness by offering group counseling courses, and have guiding significance for parents to reduce the impact of conflict on children.
