A community-based responsive caregiving program improves neurodevelopment in two-year old children in a middle-income country, Grenada, West Indies. Psychosocial Intervention

Abstract

Many young children in low- and middle-income countries (LMICs) are at risk of developmental delays. Early child development (ECD) interventions have been shown to improve outcomes, but few interventions have targeted culturally normative violence such as corporal punishment (CP). We partnered with an existing community-based ECD organization in the LMIC of Grenada to implement a parallel controlled-trial single-blind responsive caregiving intervention that educates parents about the developing brain and teaches alternatives to corporal punishment while building parental self-regulation skills and strengthening social-emotional connections between parent and child. Parents and primary caregivers with children under age two were eligible. Allocation to the intervention and waitlist control arms was unblinded and determined by recruitment into the program. Neurodevelopment was assessed by blinded testers when each child turned age two. Primary comparison consisted of neurodevelopmental scores between the intervention and waitlist control groups (Clinicaltrials.gov registration xxx NCT04697134). Secondary comparison consisted of changes in maternal mental health, home environment, and attitudes towards CP. Children in the intervention group (n = 153) had significantly higher scores than children in the control group (n = 151) on measures of cognition (p = .022), fine motor (p < .0001), gross motor (p = .015), and language development (p = .013). No difference in secondary outcomes, including CP, was detected.
