Effect of parenting centers on caregiver mental health ——Evidence from a large scale randomized controlled trial in rural China

In the context of economic development, the escalating prevalence of depression, anxiety and stress poses substantial challenges, not only impacting individuals' physical and mental well-being but also exerting a profound influence on future human capital. This study conducts an exploratory analysis of the effects of a center-based early childhood development intervention on the mental health of the caregivers, utilizing data from a cluster randomized controlled trial involving 1652 caregivers in rural China. Over the course of two years, caregivers and children in 50 villages received individualized parenting training, one-on-one parenting classes, and access to open play spaces in village parenting centers. Our findings reveal sustained and significant intervention effects on caregivers' anxiety and stress symptoms. The primary mechanisms driving these effects include increased parenting time investment, alterations in parenting styles, and changes in the level of trust in others. Furthermore, our research demonstrates that the positive treatment effects on mental health outcomes are more pronounced among caregivers of children who initially lower development skills. The intervention exhibits a stronger impact on caregivers with lower educational attainment, particularly when the caregivers are grandmothers. These results underscore the importance of governmental attention to mental health issues in rural China, suggesting avenues for intervention through the provision of parenting knowledge and spaces facilitating caregiver-child interactions. This research contributes valuable insights into addressing mental health challenges in rural settings, promoting effective strategies for future policy implementation.
