The tool consisted in a online test (in spanish), self-administered, which was composed by 60 multiple choice questions. The estimated duration was 1 hour.
For the national case, the study was implemented over a non representative sample of kids of 8 to 12 years old, from a group of metropolitan public schools.
The sample was assigned at convenience. For this reason results cannot be considered representative of the 8 – 12 population in Uruguay.
