**2.4 Procedure**

We requested the cooperation and consent of the management teams of each school and the teachers were informed of the object of the research and the nature of the help required from them. We asked them to answer questions about the children in order to classify them according to our typology and discard several problematic situations. Similarly, they had to enable researchers to carry out the evaluation sessions with pupils in which they underwent, once families' informed consent was obtained, all the relevant assessments. These assessments were carried out in groups over two sessions of one hour each. They also had to hand the FAOP questionnaire to families, along with a letter explaining the study and requesting their participation and that of their children, and be responsible for its subsequent collection. To ensure parents really filled in the scales and that they consented to their children's the evaluation they were explicitly asked to sign the questionnaire or return it in person.

Once the field work was completed, we corrected the assessments and computerized the results. We then proceeded to select the subsample which we used to perform the statistical analysis. In order to do this we used the Statistical Package for the Social Sciences (SPSS) version 17.0. Its results are presented below.
