Summary

This study aims to experimentally test the effectiveness and cost-effectiveness of competing models of delivery of an Early Childhood Development (ECD) intervention in rural Kenya to determine how to maximize their reach to improve child cognitive, language and relevant psychosocial outcomes. The study will also include a longer-term evaluation of sustained impacts; an examination of the pathways of change leading to intervention impacts to inform policy; and examination of the role of paternal involvement on child development. Findings will provide policy makers with rigorous evidence of how best to expand ECD interventions in low-resource rural settings to improve child developmental outcomes for both the short-and longer-term.

Detailed description

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 non-governmental organization (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.

Interventions

Type	Name	Description
BEHAVIORAL	Group sessions	Mother-child dyads in Arm 1 households will receive biweekly ECD sessions for a total of 16 sessions over 8 months. CHVs will record attendance at each session. To maximize participation, prior to each session the CHVs will send a short message service (SMS) mobile phone reminder of the session's topic, time and location to all participants.
BEHAVIORAL	Group+Home sessions	Households in Arm 2 will receive a total of 16 sessions with identical content similar to Arm 1, but 4 of those sessions will replace group sessions held at the level of villages for personalized home visits, in which the CHV will visit each participant household to deliver these sessions. These home visits will cover identical material and topics as the group sessions in Arm 1 villages, but will be delivered on a personalized basis in the home of the mother and child. Personal barriers to the practices will be discussed and an active resolution strategy developed in concert with the CHV.
BEHAVIORAL	Booster sessions	After the end of the 16 biweekly sessions (phase 1), we will re-randomize across the 40 intervention villages, stratified by Arms 1 and 2, and half of each of Arm 1 and Arm 2 villages will receive group booster visits every other month for the period between end-line and follow-up surveys. This will constitute Phase 2 of the study.
BEHAVIORAL	Fathers invited	During phase 1's 16 biweekly sessions, in half of Arm 1 and Arm 2 villages (20 total), fathers will additionally be invited to attend the 16 sessions. Separate father-only sessions will be held for 4 of the 16 sessions. This randomization will end after phase 1.
