Congolese mother and child mental health in response to early child development interventions

This project examines long-term maternal and child mental health outcomes following a prior early child development intervention in the Democratic Republic of the Congo (DRC). Funded through a five-year R01 from the National Institute of Mental Health, the study assesses mothers and children who participated in an earlier program in which caregivers received weekly training for a year on practical strategies to enrich the home learning environment and on nutritional approaches to support development and physical health. The current study seeks to measure enduring mental health effects in children ages 5–12 and in their mothers, exploring reciprocal influences between maternal and child mental health. The research team emphasizes that behavior and mental health are multifactorial; the project will therefore evaluate how family dynamics, social context, child growth, and maternal mental health independently and jointly shape child mental health outcomes.

Building on prior work implementing the Mediational Intervention for Sensitizing Caregivers (MISC) in Uganda and the DRC, where earlier programs targeted risks such as HIV exposure-related developmental challenges and konzo from improperly processed cassava, the present study leverages both clinical expertise and innovative measurement approaches.

A notable innovation of the project is applying state-of-the-art eye-tracking technologies to measure children’s viewing focus as they watch culturally contextualized videos of mother-child interactions. This is the first use of such measures years after caregiver training interventions to gauge emotional responsiveness and attachment, and the team intends to train Congolese neuropsychiatric colleagues at the University of Kinshasa Medical School in these methods for sustained clinical and research use. The investigators aim to identify mechanisms and mediators of mental health outcomes to inform prevention strategies and to tailor interventions that could have meaningful impact in low- and middle-income country contexts. By measuring both direct and reciprocal effects between maternal and child mental health, the study aims to deepen understanding of long-term benefits of early child development programs and to guide future programs designed to improve mental health and developmental trajectories.
