Abstract
This article seeks to illustrate how a research study that claims to be inclusive should incorporate into its development, decisions of methodological flexibility that enable voice to be given to all participants regardless of their personal conditions. The changes carried out in the techniques, procedures or in the kind of questions used in the research, illustrate how young persons can be involved in the building of scientific and academic knowledge that is being generated about them. This work forms part of a more extensive line of inquiry that started a number of years ago by two Spanish universities (Cantabria and Seville).
