Abstract

The Medium Term Effects of Home-based Early Childhood Development Intervention Impact Evaluation (ECDIIE) covered 96 small towns in central Colombia, representing a large number of small communities across a relatively big geographical area. It exploited structures in place from the government’s Conditional Cash Transfer Programme, Familias en Accion (FeA), which targets the poorest 20% of households in the country.

There are currently three waves of data, a baseline, pre-intervention wave collected between February and June 2010, and a follow-up wave 18 months later between September and December 2011, at the end of the intervention period. The second wave of follow-up data collection occurred 2 years after the first follow-up data collection between September and December 2013.

The beneficiaries of FeA periodically elect a female representative, called the Madre Lider (ML). We randomly selected three from each town (municipality), and then from the families represented by the ML we randomly selected 5 children aged 12 to 24 months to be eligible for the intervention. Within each municipality, eligible households were randomly allocated (at the municipality level) to each of the following treatment arms:

1. Control

2. Stimulation + Supplementation

3. Stimulation

4. Supplementation

The stimulation intervention consisted of weekly visits to the homes of the target children, each visit lasting around one hour. The home visitors received a three week training programme in activities designed to stimulate children at different ages. They also received a weekly curriculum as a guide, and a set of locally produced materials (homemade toys from recycling material, picture books, puzzles, etc.).

The supplementation arm consisted of providing daily sachets of multiple micronutrient powder to mothers, via the home visitors, to add to the target child's food. Sachets were designed to provide iron (12.5mg), zinc (5mg), Vitamin A (300 µg retinol equivalent), Vitamin C (30mg) and folic acid (160 µg) for the children targeted.

Data Collection Notes

The main components of the intervention were:

The development of the curriculum.
The training of professionals that could train the home visitors in the field.
The supervision of the home visitors throughout the intervention (partially funded by IGC).

Six professionals were chosen among a number of applicants on the basis of their CV and an interview. They were trained in child development, home visiting and the curriculum for over one and a half months. The training also included practicing home visits in Soacha. These professionals, who will be referred to as "mentors" in what follows, then had the task to train the home visitors in the field - i.e. teach them the curriculum and the approach to home visiting - and mentor/supervise them throughout the intervention. To this end, each of them was assigned 8 towns, for a total of 24 home visitors each.

The training of the home visitors was split across two workshops. The first, lasting two weeks, covered the first part of the stimulation curriculum (activities for children ages 12 to 30 months) along with the fundaments of child development, the importance of adequate care and stimulation, and toy construction workshops. Once this first round of training was completed, the home visitors were deemed ready to start the visits. This process took place at the same time as data collection (being careful in each village to ensure data collection had taken place before the intervention started), from February through June 2010, so by the end of June 2010 the intervention was fully phased-in across all treatment villages. The second phase of the training workshops took place between mid August and mid October 2010 over a one week period. In these sessions, the home visitor and the mentor covered the second half of the curriculum (activities for children aged 30 to 42 months), revised lessons covered in the first workshop, resolved doubts, and discussed any outstanding issues.
