The Medium-term Effects of Home-based Early Childhood Development Intervention Impact Evaluation 2013

There are four main sources of data:

• Household survey
• Child Developmental Assessments
• Intervention Data
• Community Survey

Household Survey
This collected information on the household and on household members in a set of modules (questionnaires) administered by interviewers. The mapping from the questionnaires to the raw datasets is shown in tables 2 and 3. Note that some additional questions were asked in the follow-up II round while other questions were removed, so it is worth checking the wording of questions in the original questionnaires.

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.

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
In the dataset tests_TC we include the raw scores for each child assessment. These can be linked to other datasets using key_2s.
More details of the scoring and administration of each test is available in the document “guide to scoring and administration of child assessment data”

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
In the dataset tests_mother we include the raw scores for each of these assessments. These can be linked to other datasets using key_2s.

Assessments for younger siblings
We used the ASQ-3 to assess child developmental levels of the younger siblings. This assessment occurred in the household. Item level data is available in the file asq_sibs.

Community Survey
This collects the information at the municipality level included in the questionnaire “community”. This includes information on shocks, services, wages, prices. The data are included in the datasets com_1-com_5 and the key identifying variable for merging to other datasets is “comunidad” which is identical to “dane” in the other datasets.
