Specific Aim 1: Assess the effectiveness of the GMCD intervention to improve developmental outcomes and nurturing care in India and Guatemala. The investigators will conduct a parallel-arm cluster randomized trial within rural CHW programs. In the primary effectiveness phase, children under 2 years old will receive the GMCD intervention or control for 12 months. Subsequently, control clusters will cross into the intervention, and continue an additional 12 months (total 24 study months). The primary developmental effectiveness outcome will be change in age-adjusted scores at 12 months on the Bayley Scales of Infant Development, 3rd Edition BSID3) (3). The secondary nurturing care effectiveness outcome will be change in mean Home Observation for Measurement of the Environment (HOME) score at 12 months (4).
Specific Aim 2: Assess barriers and facilitators to GMCD implementation using the RE-AIM evaluation framework (5). RE-AIM domains will be assessed as: (a) Reach: participation rates, comparison of participant/non-participant characteristics, attendance/drop-out; (b) Effectiveness: impact on development (BSID3) and nurturing environment (HOME) [in Aim 1]; (c) Adoption: proportion of workers/facilities participating, CHW characteristics; (d) Implementation: contact hours/visit completion, fidelity to delivery protocols; (e) Maintenance: patient outcomes and cost effectiveness analysis at 12-24 months [in Aim 3]; intent by decision makers and implementers to continue intervention. In addition, the investigators will conduct a sequential quantitative-->qualitative explanatory analysis, using interviews and focus groups with implementers from clusters with highest/lowest impact outcomes (BSID3/HOME) to explore institutional inner and outer setting and implementation processes associated with intervention success, using the Consolidated Framework for Implementation Research (CFIR).
Specific Aim 3: Conduct an economic evaluation of the GMCD intervention. Evaluation will assess (a) costs of the interventions at 12 and 24 months; and (b) cost-effectiveness of the intervention (dollar per unit increase in BSID or HOME scores) at 12 months. This analysis will provide cost information to policymakers to help guide resource allocation decisions for ECD interventions.

Arm | Intervention/treatment |
---|---|
Experimental: Intervention arm
Subjects from intervention clusters will receive the GMCD intervention, delivered in monthly visits to the home by frontline health workers, for 24 months. 0-12 months represents the primary effectiveness study, and 12-24 months a secondary maintenance study.
|
Behavioral: International Guide for Monitoring Child Development
Monthly GMCD visits includes assessment of risk factors, open-ended exploration of caregiver concerns about development, assessment of functioning in seven developmental domains, and using mutual problem solving strategies to develop a nurturing care plan with the caregiver. |
No Intervention: Control Arm
Subjects in control clusters will continue to receive usual care from their frontline health workers. After 12 months (primary effectiveness study) control will cross into the intervention for months 12-24.
