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.
我们展示了一项整群随机对照试验的结果,该试验评估了一项免费的、以中心为基础的育儿干预措施对中国100个乡村早期认知发展和育儿实践的影响。然后,我们将这些影响与之前在同一地区进行的一项以家庭为基础的干预试验进行比较,该试验使用相同的育儿课程和公共服务系统,并考虑到两项研究之间的潜在差异。我们发现,以中心为基础的干预对儿童发展结果没有显著影响,但确实导致了照料者在物质投入、时间投入和育儿技能方面的增加。以中心为基础的干预对儿童技能和对儿童投入的平均影响明显小于家访干预。对可能机制的分析表明,效果差异主要是由参与项目的不同选择模式驱动的。
