Effects of Integrating Early Childhood with Health Services: Experimental Evidence from the Cresça com Seu Filho Home-Visiting Program
通过随机实验评估一个与医疗体系结合的家访项目，发现其对家庭环境质量有微小正面影响，但对儿童发展和健康无显著效果，提示实施中的工作量、监督和配合度是关键。
Delivering early-childhood programs at scale is a major policy challenge. One way to do so is by using existing public infrastructure. This paper experimentally assesses the short-term effects of a new government home-visiting program integrated into health-care services. The program changed the allocation of time for community health workers by asking them to carry out tasks related to early-childhood development. We find that access to the program has a positive but modest effect on home environment quality and no effect on child development or on children’s health status. Our results point to the importance of workload, supervision, and buy-in from delivery actors to enhance fidelity of interventions.
