学龄前留守儿童亲子依恋对执行功能的影响:祖孙依恋的调节作用和中介作用

本研究探究了学龄前留守儿童亲子依恋、祖孙依恋与执行功能之间的关系，并进一步分析了祖孙依恋的调节作用和中介作用。对155名南昌市农村地区的学龄前留守儿童及其父母亲和（外）祖父母进行研究，研究工具包括亲子依恋量表（Waters Attachment Q-sort Items）和执行功能任务组。结果表明：（1）学龄前留守儿童亲子依恋与祖孙依恋、执行功能子成分抑制控制呈显著正相关，祖孙依恋与执行功能子成分抑制控制和认知灵活性呈显著正相关；（2）祖孙依恋在亲子依恋对学龄前留守儿童执行功能子成分抑制控制的影响之间存在调节效应；（3）祖孙依恋在亲子依恋对学龄前留守儿童执行功能子成分抑制控制和认知灵活性的影响之间存在中介效应。结论是可通过改善亲子依恋和祖孙依恋的质量来促进儿童执行功能的发展。

The Influence of Parent-child Attachment on the Executive Function of Left-behind Preschool Children: Grandparent-child Attachment as a Mediator and Moderator

This study examines the relationship of the executive function of left-behind preschool children with grandparent-child attachment as both a mediator and a moderator and parent-child attachment. A total of 155 preschool children left behind in rural areas of Nanchang, their parents and grandparents were interviewed combined with the executive function task set and Waters Attachment Q-sort Items. The following results can be obtained:(1) parent-child attachment was positively correlated with grandparent-child attachment and the executive functional subcomponent of inhibitory control ability at a significant level; grandparent-child attachment is significantly positively correlated with the executive functional subcomponent of inhibitory control ability and cognitive flexibility; (2) grandparent-child attachment played a moderating role in the impact of parent-child attachment on the inhibitory control ability of left-behind preschool students; (3) grandparent-child attachment played a mediating role in the impact of parent-child attachment on the inhibitory control ability and Cognitive flexibility of left-behind preschool students. It is hence concluded that the development of children's executive function can be promoted by the increasing quality of parent-child attachment and grandparent-child attachment.
