Tracking longitudinal sample of the long term impact evaluation of Nadie es Perfecto through administrative data.

A recent experimental study (Carneiro et al., 2024), shows that Nadie es Perfecto (NEP), a low-cost group based parenting program in Chile targeted to poor families and delivered at scale by the national health system, achieved gains in parenting behaviors and child development outcomes that were sustained almost three years after the end of the intervention. The intervention was evaluated with a Randomized Control Trial (RCT) across 162 health centers nationwide. A baseline survey was collected in July-Sep 2011. A follow-up assessment was conducted during Oct-Dec 2014, roughly 2.5-3 years after the end of the intervention, and found that children of households participating in the program had language and socioemotional scores above children in the control group.

The consultancy is for a new follow-up with the original study sample to administer a longer-term follow-up survey as well as assemble information from administrative health and education records, to measure children’s outcomes after 14 years of the original follow-up. The original NEP study, including the intervention, as well as baseline and the 3-year follow-up surveys, were approved by the local IRB Board at the South-East Metropolitan Health Service, which is part of the national network of Health Services of Chilean Ministry of Health. All caregivers included in the NEP sample signed a consent form at baseline allowing the research team to match administrative records using their national ID for the purpose of the study and its follow-up rounds.
