We present results from a large-scale experimental evaluation of a national parenting program in Chile. The program is low cost: it lasts only 6–8 weeks, and it is administered to groups of eight to 12 parents. It is implemented by the national health system, taking advantage of its existing physical infrastructure and human resources. We find that 3 years after the interventions ends, children whose parents are offered the opportunity to participate in this program increase their vocabulary and socioemotional development scores by 0.1 standard deviations, mirrored by similar improvements in caregiver’s parenting behaviors and beliefs.

大规模育儿计划的影响：来自智利的实验证据

我们展示了对智利国家育儿计划进行的大规模实验评估的结果。该计划成本低廉：仅持续 6 至 8 周，并以 8 至 12 名家长为一组进行。它由国家卫生系统利用其现有的基础设施和人力资源来实施。我们发现，干预结束 3 年后，父母有机会参与该计划的孩子的词汇量和社会情感发展得分增加了 0.1 个标准差，这反映在照料者的养育行为和信念方面也有类似的改善。
