Effect of a playful parenting programme on early childhood development and care outcomes of young children in vulnerable communities: Findings from a quasi-experimental study

Background: World Vision launched the Inclusive Playful Parenting for a Brighter Childhood (IPP4BC) project in identified vulnerable communities in Nepal and Uganda to mitigate risk for children at risk of poor development due to COVD 19. The intervention, based on the nurturing care framework, offered a customized parenting curriculum for young children, emphasizing holistic development through behavior change approaches tailored to local contexts. Objective: To evaluate the effect of the IPP4BC project, on early childhood development (ECD) and care outcomes of children under 6 years in vulnerable communities in Nepal and Uganda, particularly those affected by the COVID-19 pandemic. Methods: The intervention was delivered by trained facilitators over a 7-month period in different arms defined by the dosage: high (10 group sessions, 4 home visits) medium (5 group sessions, 2 home visits) or low (delivery of key messages through media) dose. An endline evaluation designed as quasi-experimental non-equivalent control groups post-test only study, assessed the effect of the project utilizing the Malawi Development Assessment Tool (MDAT) for child outcomes and the Multiple Indicator Cluster Survey (MICS) for caregiver outcomes. Additionally, an implementation survey was conducted to assess program fidelity and participant engagement. Findings: In Nepal, higher intervention doses were associated with significantly better child development outcomes (High dose M = 1.20, SD = 2.22, Medium dose M = 1.01, SD = 1.99; Low dose M = 0.43, SD = 2.32, p < 0.001) whereas in Uganda, only medium dose (M = -0.03, SD = 1.28) showed significant improvement (High dose M = -0.30, SD = 1.30; Low dose M = -0.28, SD = 1.51, p = 0.015). A higher proportion of caregivers in both high and medium dose reported engagement with early learning practices compared to low dose. With respect to uptake, in Nepal, a higher number of families received home visits compared to group sessions, while in Uganda, more families reported attending group sessions than receiving home visits. Conclusion: The study demonstrated that higher intervention doses were associated with better child development outcomes in Nepal and only with medium dose in Uganda, emphasizing the importance of implementation factors like dosage, quality and delivery modality in community-based interventions for improving ECD outcomes in vulnerable populations.
