Integrated Early Childhood Development in Cambodia: Protocol of a Cluster Stepped-Wedge Trial.

Objectives: Limited evidence is available on mechanisms linking integrated, multisector interventions with early childhood development. The Integrated Early Childhood Development program aims to improve children's development by promoting targeted caregiving behaviors beginning prenatally through age 5 years, in partnership with the Royal Government of Cambodia.

Methods: This cluster stepped-wedge trial is being conducted in Cambodia among 3 cohorts, encompassing 339 villages and 1790 caregivers who are pregnant or caring for a child aged <5 years.

Leveraging item-level accuracy and reaction time to address ceiling effects in the measurement of inhibitory control in preschool-aged children.

Preschool-aged children's performance on inhibitory control tasks is typically represented by the overall accuracy of their item responses (e.g., mean proportion correct).

Testing the Efficacy of the Red-Light Purple-Light Games in Preprimary Classrooms in Kenya.

This study adapted and tested the efficacy of the Red-Light Purple-Light (RLPL) games for improving executive function (EF) skills in preprimary classrooms in Nairobi, Kenya. A cluster randomized controlled trial was used to evaluate the efficacy of the adapted RLPL intervention. Specifically, 24 centers (including 48 classrooms) were randomized to the RLPL or a wait-list control condition.

Measuring executive function skills in young children in Kenya: Associations with school readiness.

Most of what is known about the association between children's executive function (EF) and school readiness skills is derived from research conducted in Western countries. We tested whether these associations were evident in a middle-income country context. Participants were 1,480 children, aged 4-7 years old, who participated in an endline assessment of the Tayari program, an early childhood education (ECE) model that is being delivered by the Kenyan education system.
