Improve Child Outcomes Through Caregiving in Cambodia

This study is a longitudinal, randomized-controlled study with a stepped-wedge research design. The Integrated Early Childhood Development Activity (IECD) will implement interventions in three cohorts of villages sequentially across two provinces of Cambodia, Kampong Thom and Preah Vihear. IECD will collect data from all three cohorts together, four times, at 12-month intervals: a baseline prior to any program intervention, a Cohort 1 end line, a Cohort 2 end line and a Cohort 3 end line. IECD's Theory of Change is that by changing caregivers' practices in rearing their children under age 5, those children will demonstrate improvements in child development outcomes. The investigators will use 6 instruments to collect this data, including well-established internationally validated measures. The IECD team enrolled 1,790 households in Preah Vihear and Kampong Thom in June and July 2021. The study will be competed in 2025.
