母子依恋与农村儿童焦虑的关系:HPA轴活动的调节作用

The Relationship Between Mother-Child Attachment and Rural Children’s Anxiety:The Moderating Role of HPA Activity

本研究考察了母子依恋与农村留守、非留守儿童焦虑的关系以及儿童的HPA轴活动(唾液皮质醇日常节律)对这一关系的调节作用。39名留守儿童和70名非留守儿童完成了母子依恋问卷、儿童焦虑量表和连续三天共6次(上午、下午)的唾液采集。结果发现:(1)母子依恋安全性与留守儿童焦虑的负相关程度高于非留守儿童;(2)伴随皮质醇日常变化节律的提高,母子依恋安全性对留守儿童焦虑的保护作用增强,对非留守儿童焦虑的保护作用减弱。结果表明,HPA轴活动与母子依恋安全性的交互作用模式在农村留守与非留守儿童之间存在差异性。

The present study examined the association among mother-child attachment security and rural left-behind and non-left-behind children’s anxiety, as well as the moderating role of children’s HPA activity in such association. A total of 39 children from leftbehind families and 70 children from non-left-behind families completed the Kern Security Scale, Spence Children’s Anxiety Scale,whose saliva were collected during morning and afternoon in three consecutive days. Results were as follows: 1) Negative association between mother-child attachment security and left-behind children’s anxiety was higher than that of non-left-behind children. 2) High decline in diurnal cortisol change enhanced the protective role of mother-child attachment security on left-behind children’s anxiety and decreased the protective role of mother-child attachment security on non-left-behind children’s anxiety. These findings demonstrate that the interactive effects of mother-child attachment security and diurnal cortisol change on children’s anxiety varies from rural left-behind to non-left-behind children.
