Impacts of a Large-Scale Parenting Program: Experimental Evidence from Chile
研究评估了智利一项低成本、短周期的全国育儿项目，发现参与家庭的孩子在词汇和社会情感发展上提升0.1个标准差，同时改善了看护人的育儿行为和观念。
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.
