An exploratory descriptive study was completed, with a quantitative-qualitative methodology. A sample of 730 girls, boys and

adolescents between 6 and 14 years of age was defined for the application of the test; the expert judgment technique was used. The

analysis of the data was carried out through a psychometric analysis of the items, and by the triangulation method. Results: From

the 730 participants included, 44.5% were from rural areas (n= 325) and 55.4% from urban areas (n= 405), by sex, they were valued

n=378 (51.7%) girls and n=352 (48.2%) boys. The level of difficulty and the coefficient of discriminative effectiveness for the items

were calculated, which together with the experts’ findings resulted in 22 modifications of items, and creation of 4 new items at the

cognitive and language areas; also, the qualification was changed by areas, therefore the manual was improved, and new materials

were created. Conclusions: The research provides a validated screening test for child and adolescent population, which was included
