Passive versus active service delivery: Comparing the effects of two parenting interventions on early cognitive development in rural China
通过集群随机对照试验，评估免费中心式育儿干预对中国农村儿童早期认知发展的影响，并与同一地区的家访干预比较，发现中心式干预对儿童技能影响较小，差异主要由参与模式不同驱动。
We present the results of a cluster-randomized controlled trial that evaluates the effects of a free, center-based parenting intervention on early cognitive development and parenting practices in 100 rural villages in China. We then compare these effects to a previous trial of a home-based intervention conducted in the same region, using the same parenting curriculum and public service system, accounting for potential differences between the studies. We find that the center-based intervention did not have a significant impact on child development outcomes, but did lead to increases in the material investments, time investments, and parenting skills of caregivers. The average impact of the center-based intervention on child skills and investments in children was significantly smaller than the home-visiting intervention. Analysis of the possible mechanisms suggests that the difference in effects was driven primarily by different patterns of selection into program participation.
