Some medical terms are more difficult to understand than others, especially when discussing complex pathologies or rare tests. Children, however, may initially encounter this difficulty with even the most basic vocabulary, encompassing everyday health terms and related concepts. For this reason, medical vocabulary specialists from Pompeu Fabra University (UPF) in Barcelona have collaborated with over 3,000 children and young people from schools and institutes throughout Catalonia to develop a platform to explain medical terms to children in their own words, using new digital and multimedia formats. This platform, called Diximed, is aimed at children and families, as well as pediatricians and educators. "You have to approach the child's needs, but keeping in mind a psycholinguistic theory that says nothing is learned in leaps and bounds, but always from what is already known. And if what a child knows is incorrect and no one explains it to them, they will always end up carrying that misconception," says Rosa Estopà, principal investigator of the Lex project, a research group at Iulaterm. To carry out this initiative, the participating children were asked to explain what they knew about certain words, such as flu, louse, vaccine, coronavirus, cancer either chickenpoxAmong many others, they were asked to draw them. "We told them they had to do it as if they were explaining it to a child their age who came from another planet," Estopà recalls.
