This version of the data is identical to version 1.0, aside from revisions made to update labeling for a few variables and to remove some empty variables as well.
The scope of this study includes:
A community survey covering topics including shocks, services, wages, and prices.
Assessments of outcomes of the target child, the mother of the target child, and younger siblings.
This project 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.
The universe of the target population is given by households who are eligible to receive the government's Conditional Cash Transfer Programme, Familias en Accion (FeA), which targets the poorest 20% of households in the country.

The survey used a randomized experimental design to obtain rigorous and unbiased estimates of the impact of the stimulation and nutrition interventions, and of their interaction.
The beneficiaries of Familias en Accion 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:
These MLs were then asked to take on the role of home visitor to implement the intervention of the different treatment arms. However, a significant proportion (nearly 40%) of the MLs either opted out or were not deemed suitable for the role, in which case they were replaced following their recommendations. In order to maintain the randomization of the design, the families attached to the original ML were maintained, even if in the end she was not the actual home visitor.
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.
This study included four main sources of data: a Household Survey, a Community Survey, Intervention Data, and Child Developmental Assessments.
Household Survey:
This collected information on the household and on household members in a set of modules (questionnaires) administered by interviewers. Separate questionnaires were asked at household and individual levels. At the individual level there are several standalone modules for the mother, children under six years old, the target child of the intervention, the main care giver, and the home visitor. The modules contain a rich variety of data: the home environment and composition of the household; education and health; employment and time use etc. There are also a series of modules on child development. The questionnaires for each of the modules are provided in Spanish and are available to download.
Community Survey:
This collects the information at the municipality level included in the questionnaire “community” and includes information on shocks, services, wages, prices. The questionnaire is provided in Spanish and is available to download.
Assessment of Outcomes of the Target Child:
In additional to the information collected in the questionnaires administered by interviewers at the household level, the target children also attended a centre where her developmental level was assessed by a trained psychologist using a variety of assessments:
· Test de Vocabulario en Imagenes Peabody (TVIP) to assess receptive language
· Daberon (modified) to assess school readiness
· Pencil Tapping Task to assess executive functioning
· Wolke to assess Emotional tone, activity, co-cooperativeness, approach
· Woodcock-Munoz Achievement 14 to assess expressive language
· Woodcock-Munoz Cognitive 5 to assess fluid reasoning/fluid intelligence
· Woodcock-Munoz Cognitive 6 to assess visual perception/processing speed
· Woodcock-Munoz Cognitive 12 to assess fluid reasoning
· Woodcock-Munoz Cognitive 13 to assess visual perception/spatial memory
· Woodcock-Munoz Cognitive 16 to assess speed processing
· Woodcock-Munoz Cognitive 21 to assess long term memory
Assessments for Mother:
In the test centre we also performed some assessments with the mother of the target child:
· Raven's progressive matrices to measure IQ
· CES-D 10 point depression scale
· Big Five to measure personality traits
Assessments for Younger Siblings:
We used the ASQ-3 to assess child developmental levels of the younger siblings. This assessment occurred in the household. The questionnaire is provided in Spanish and is available to download.

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.
After that, the six mentors became, for the rest of the intervention, mentors and supervisors of the home visitors. They traveled around each of their 8 towns, spending up to a week in each, overseeing visits of their assigned home visitors and providing them with advice, training, feed-back, and support. This rotation scheme is such that each home visitor received about a week of interaction with her mentor once every 4-6 weeks. Furthermore, mentors and home visitors are in touch on a regular basis: the home visitors receive weekly to fortnightly telephone calls to discuss progress and problems; they receive weekly text messages to reinforce key messages to be conveyed during home visits, and they receive monthly one-page bulletins that reinforce material covered during training sessions. Overall, the mentors have played a very important role in the intervention.
