Study summary

The overall objective of the study is to examine the effects of integrating early child development group sessions into the existing, at-scale, community health and nutrition programs administered by the government in Madagascar.

Read the detailed description

This research is a cluster-randomized trial that will assess the effects of integrating early child development activities on community health worker time use and caregiver time use and participation in the program. The evaluation will compare the addition of early child development sessions to the status quo health and nutrition program, with an additional intervention arm looking at the addition of toys to the program.

This study has four objectives, which will be measured at the community health worker level, and at the caregiver level for caregiver-child dyads (where children are between 6-30 months old at time of intervention launch):

  1. Measure how the integration of ECD activities with standard nutrition programming affects the time and task allocation of the community health workers
  2. Measure the extent, if any, that the addition of ECD activities crowds out community health worker health/nutrition tasks that are part of the standard community program
  3. Measure how the integration of ECD activities affects rates of caregiver participation in nutrition and health activities over time (e.g., during changes in seasonal activities).
  4. Measure the impact of enhanced availability and maintenance of age-appropriate play materials/activities on sustained caregiver participation rates in the program.

Eligibility criteria

Inclusion Criteria for communities:

  1. No other ECD programs present in the community or neighboring communities;
  2. At least 40 children monitored at the nutrition center in the target age range of 6-30 months (monitored is defined as attending at least one growth monitoring session between July 2019 to August 2020);
  3. Stable supervisory presence. Local NGOs are contracted to monitor and supervise all community health workers and help to strengthen linkages with local structures such as the community health committees and primary care facilities. Each NGO supervisor is in charge to up to 9 communities, which they visit twice a month. The investigators defined stable presence as not having had NGO turnover within the last year.

Among the communities included, children 6-30 months were eligible to participate in the intervention. There was no inclusion criteria for community health workers.

Study arms

  • No intervention
    Control (C): Status quo health and nutrition program
  • Experimental
    Treatment (T): adaption of Reach Up and Learn home visiting program to a group setting

    Behavioral: Treatment (T)

  • Experimental
    Treatment + (T+): Enhanced play materials/activities package

    Behavioral: Treatment + (T+)

Interventions

  • BehavioralTreatment (T)

    Children area offered to participate in bimonthly group sessions. Each session will have materials and activities appropriate for children spanning a 6-month range (6-12 m, 12-18 m, 12-24 m, 24-30 m) and can accommodate a maximum of 10 children per age group. If more households are interested than can be accommodated by the program, interested families will be randomly selected for participation. A total of 40 children per site will be able to participate in the ECD activities at any one time. With bi-monthly meetings, each child will be exposed to 12 sessions for each age group, and is eligible to transition to the next.

  • BehavioralTreatment + (T+)

    Caregivers/children participating to the group ECD sessions will be invited to play within a play space equipped with books, and homemade/purchased age-appropriate toys. This will be phased in after 6 months of implementation.

What researchers measure

Primary outcomes

  1. Community health worker time use

    Proportion of working day spent on community health worker activities, measured through recall of hourly time use using monthly phone surveys

    Time frame: Up to 12 months

  2. Caregiver-child attendance in health and nutrition sessions

    Monthly attendance in health and nutrition sessions, measured through session attendance records (0 = Did Not Attend, 1 = Attended)

    Time frame: Up to 12 months

  3. Caregiver-child attendance in ECD group sessions

    Monthly attendance in ECD sessions, measured through session attendance records (0 = Did Not Attend, 1 = Attended)

    Time frame: Up to 12 months

Secondary outcomes

  1. Community health worker stress

    Perceived Stress Scale 4 (PSS-4) administered monthly (Low: 0, High: 16, Higher scores are correlated to more stress)

    Time frame: Up to 12 months

  2. Community health worker depressive symptoms

    Center for Epidemiologic Studies Depression Scale-10 (CESD-10), administered quarterly (Low: 0, High: 30, Higher scores indicate worse symptoms)

    Time frame: Up to 12 months

Individual participant data

Plan to share: Yes — In accordance with the World Bank's Open Data and Knowledge Initiative, the deidentified data collected in the study will be made publicly available at the data repository at the World Bank, which is expected to be within 24 months of the final data collection date. Metadata and critical documents (i.e. protocols and questionnaires) will conform to the standards of the Data Documentation Initiative and will be made available within one year of the end of data collection.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 27, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
