The Influence of Grandparent-parent Coparenting Relationship on Sibling Jealousy in Multi-Child Families: The Role of Maternal Parenting Burnout

This study involved a sample of 767 mothers from multi-child families in regions such as Beijing and Jiangsu Province. It utilized an explanatory sequential mixed-methods design to investigate how intergenerational dynamics between grandparents and parents, influenced by maternal parenting burnout, impact early sibling jealousy in children. Initially, the quantitative phase employed SPSS 20.0 and AMOS 28.0 to assess the mediation model. The findings revealed that consistency and conflict in the grandparent-parent co-parenting relationship indirectly predicted early sibling jealousy in children through maternal parenting burnout. The qualitative phase featured semi-structured interviews with 10 mothers representing diverse parenting styles, selected via stratified sampling from existing data. The results indicated that the intergenerational transmission of the grandparent-parent co-parenting relationship and maternal burnout primarily occurs through perceived fairness, observational learning, and emotional projection related to sibling jealousy. This research expands the application of intergenerational transmission theory within family systems and provides practical insights for group interventions in multi-child families,
