Despite extensive studies about the direct effect of grandchild care on caregiver depression in China, understanding of its internal influencing mechanism has been limited. After controlling for socioeconomic factors, this study investigated whether the experience of caring for grandchildren had a long-term impact on the depression levels of grandparents, either directly or indirectly through generational support from adult children.
The subjects of this study were a total of 9,219 adults over 45 who participated in the China Health and Retirement Longitudinal Surveys in 2015 and 2018. We adopted a lag-behind variable to examine the impact of grandchild care on depressive symptoms of grandparents. The proposed mediation model was analyzed using bootstrap modeling, and the KHB method was conducted further to examine differences in the effects of generational support.
The experience of caring for grandchildren had a significant negative correlation with the depression level of Chinese grandparents. Moreover, children's support significantly mediated the impact of parenting experience on grandparents' depression. Significantly, instrumental support mediated the effect to the greatest extent, while emotional support from children contributed the least. The intermediary effect has urban-rural heterogeneity.
These findings indicated that grandchild care significantly inhibited the depression level of Chinese grandparents through increased intergenerational support from adult children. The implications of the study's findings were discussed.
尽管有大量研究探讨了照料孙辈对照料者抑郁的直接影响,但对其内在影响机制的理解仍有限。本研究在控制社会经济因素后,调查了照料孙辈的经历是否会通过子女的代际支持,直接或间接地对祖辈的抑郁水平产生长期影响。
本研究的对象共有 9219 名 45 岁以上的成年人,他们参加了 2015 年和 2018 年的中国健康与退休纵向研究。我们采用滞后变量来检验照料孙辈对祖辈抑郁症状的影响。采用自举建模分析提出的中介模型,并进一步采用 KHB 方法检验代际支持效应的差异。
照料孙辈的经历与中国祖辈的抑郁水平呈显著负相关。此外,子女的支持显著中介了养育经验对祖辈抑郁的影响。重要的是,工具性支持的中介作用最大,而子女的情感支持作用最小。中介效应具有城乡异质性。
这些发现表明,照料孙辈通过增加子女的代际支持,显著抑制了中国祖辈的抑郁水平。讨论了研究结果的意义。
