Scientific title

Home and health centre delivery of early childhood stimulation: cluster randomised trial of the impact of interventions to improve parenting of children aged 2-18 months on child development in the Caribbean countries


Study hypothesis

There is substantial evidence from efficacy trials of benefits to child development from parenting programs with home visits to improve mother-child interaction and demonstrate activities to promote development. The interventions were delivered by paraprofessionals who visited the homes weekly. Although low cost compared to programs in the USA, these interventions are often too expensive to take to scale in many countries. The challenge is to develop programs that are feasible at scale yet remain effective. We are evaluating a modified home visiting approach using fewer visits and materials and a new health centre approach using a specially designed video of child development messages to be shown at all child health visits from age 2-18 months.

We hypothesise:
1. A home visiting intervention delivered by trained community health workers every 2 weeks from age 6-18 months with the objective of helping mothers promote their child development will improve parent-child interaction, quality of stimulation in the home and child development.
2. A health centre based intervention at routine child health visits from age 2-18 months using videos of child development messages that demonstrate mother-child interactions followed by discussion and practice led by trained community health workers will improve parent-child interaction, quality of stimulation and child development.

Early child development


1. In Jamaica 20 Health centres will be randomly assigned to one of 4 groups:
1.1. Health Centre intervention
1.2. Home visit
1.3. Both interventions
1.4. Control
2. In Antigua and St Lucia 10 health centres in each country will be randomly assigned to Health centre intervention or control
3. Participants (mothers and infants) will be recruited at the health centre at the 6 week post natal clinic visit
4. Follow-up assessment will be at age 19-20 months
5. Health centre intervention: video will be developed, in collaboration with a team experienced in effective use of media for health education, to deliver a series of child development messages. The videos will be shown at all child health clinics which are scheduled at 3, 6, 9, 12 and 18 months of age.
7. In each clinic a community health worker will be trained to discuss the video messages with the mothers, demonstrate activities mothers can do with their children and how to make simple toys from household materials
8. Opportunities will be given for mothers to try some of the activities and they will be encouraged to make them part of their daily routine
9. Home visiting intervention: will be based on that used previously in Jamaica modified to increase the feasibility of scaling up
10. Visit frequency will be reduced from weekly to twice monthly and supervision will be by nurses rather than a child development specialist
11. Children will be visited from 6 to 18 months of age by trained community health workers and play sessions conducted to improve mother-child interaction and show mothers how to promote development
12. Separate training workshops will be held for the community health aides involved in the two types of interventions
13. A supervisor will provide ongoing support to implementation of the interventions
14. Control: centres will continue to provide the usual care at all child health visits

Drug names

Primary outcome measures

1. Child Psychomotor development: Griffiths Scales of Mental Development to assess the childrens' development at age 19-20 months
2. The scales have been used frequently in Jamaica where it has good concurrent and predictive validity
3. Language development: the short version of the MacArthur Communicative Development Inventory (Short Communicative Development Inventory, CDI) will be used to measure language development based on mothers' report

Secondary outcome measures

1. Child growth: weight, length and head circumference will be measures on enrolment at age 6-8 weeks and at age 19-20 months
2. Child behaviour: ratings of behaviour during the developmental test session
3. Maternal parenting knowledge, practices and depressive symptoms will be measured on enrolment and at age 19-20 months
4. Mothers’ knowledge of child development will be assessed by questionnaire
5. Stimulation in the home will be assessed with a subset of questions from the Home Observations for Measurement of the Environment (HOME)
6. Maternal depressive symptoms will be assessed using the CES depression scale
