Testing Means to Scale Early Childhood Development Interventions in Rural Kenya

Recent neurobiological and psychological research has established that vital development
occurs in language, cognitive, motor and socio-emotional development during the first few
years of life, and early life outcomes are key determinants of adult outcomes such as
educational achievement, labor market outcomes, and health. Yet more than 200 million
children under age five in low and middle income countries (LMICs) will fail to reach their
developmental potential as adults, predominantly due to poverty, poor health and nutrition,
and inadequate cognitive and psychosocial stimulation. Early childhood development (ECD)
interventions that integrate nutrition and child stimulation activities have been proposed as
a powerful policy tool for the remediation of early disadvantages in poor settings, and
numerous field studies have shown they can be effective in improving children's developmental
and health outcomes, at least in the short-term. Key questions remain on what models of
delivery are the most effective and cost-effective that can be potentially scalable in LMICs,
as well as how to sustain parental behavioral changes over time, which can lead to long-term
improvements in child development and the possibility of positive spillovers to benefit
younger siblings. Having a better understanding of the underlying behavioral pathways leading
from intervention, to parental behavior changes, to child impacts, is also key to inform
policy about the optimal design of interventions to maximize their scalability and
sustainability. This study will conduct a multi-arm clustered randomized controlled trial
across 60 villages and 1200 households in rural Western Kenya that tests different
potentially cost-effective delivery models for an ECD intervention with a curriculum that
integrates child psychosocial stimulation and nutrition education. Selected households will
undergo baseline and follow-up surveys to measure short-term impacts in parental behaviors
and children's developmental outcomes, and the study will collect data on potential mediators
of parental behavioral change to uncover the pathways leading to impacts. Two follow-up
surveys, one immediately after the end of the planned intervention and a second two years
later, will enable testing of the short term and midterm sustainability of impacts, as well
as the presence of any spillovers onto younger siblings. In collaboration with a local NGO,
the Safe Water and AIDS Project (SWAP), community health volunteers (CHVs) will be trained to
implement the intervention by introducing the ECD curriculum in their villages.

The goal of this study is to provide policymakers with rigorous evidence of how best to
expand ECD interventions in low-resource rural settings.

Inclusion Criteria:

- Kenyan mothers or equivalent female primary caretakers aged 15 and over with children
aged 6-24 months (classified as mature minors)

- Kenyan fathers aged 18 and older with children aged 6-24 months with a mother present

The unit of observation for the study is the household or family, within which the primary
focus is mother-child dyads and household eligibility hinges on the age of the child. For
those households with a father present, the study will additionally include him in some
analyses and surveys.

Exclusion Criteria:

- Households without children

- Households with children that are outside the age range of 6-24 months at baseline

- Households with a mother younger than 15 or one aged 15-18 still living with her
parents

- Single fathers

Selection criteria for fathers are based on the mother-child eligibility criteria. Fathers
will be included if and when appropriate per the details surrounding the mother-child
dyads.
