2.2. Procedure
The present study was part of a broader investigation approved by the University of Minho Ethics Committee for Research in Social and Human Sciences (CEICSH) (CEICSH 032/2019). Elementary school children and their parents or legal guardians were informed about the study’s aims and assured of the data’s confidentiality. Afterward, parents or legal guardians of the participants provided written informed consent and children provided assent to participate. Before data collection, researchers participated in a training session hosted by a senior researcher to set the protocol for data collection. Researchers administered the instruments (discussed below) during regular classes as follows: children were invited by the researcher to fill in the instruments and were asked to complete the task by themselves; each child fulfilled the instruments at their own pace, and was supported by the researcher in items found to be unclear. When in doubt about an item, that sentence was explained to the whole class similarly. The children took approximately 30 min to complete the instruments in Qualtrics XM survey platform
