Hybrid type 1 effectiveness/implementation trial of the international Guide for Monitoring Child Development:...

Area of Science:

• Global child development
• Early childhood intervention programs
• Implementation science

Background:

• Over 40% of young children in low- and middle-income countries risk developmental delays.
• The Guide for Monitoring Child Development (GMCD) is an early intervention package designed to address these challenges.
• Individualized intervention plans are crucial for supporting young children and their families.

Purpose of the Study:

• To conduct a hybrid type 1 effectiveness-implementation evaluation of the GMCD intervention.
• To assess the impact of GMCD on developmental functioning and nurturing care in young children.
• To explore factors influencing the effectiveness of GMCD implementation in diverse settings.

Main Methods:

• A cluster-randomised trial involving 624 children aged 0-24 months in India and Guatemala.
• Intervention delivered via a digital mobile device interface by frontline workers over 12 months.
• Outcomes assessed using the Bayley Scales of Infant Development and Home Observation for Measurement of the Environment Scale; implementation evaluated using the RE-AIM framework.

Main Results:

• Effectiveness of the GMCD intervention on child development and nurturing care will be assessed.
• Implementation effectiveness will be measured using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework.
• Qualitative analysis will identify determinants of high versus low implementation effectiveness.

Conclusions:

• The GMCD intervention has the potential to address critical developmental needs in young children.
• This study will provide valuable insights into the effectiveness and implementability of GMCD in resource-limited settings.
• Findings will inform the scale-up of effective early childhood interventions globally.
