A Youth Advisory Board will be set up to ensure that this consortium not only works for but also with adolescents and emerging adults. The Board consists of adolescents and young adults, and we will ensure that gender, education level, and socioeconomic status are a fair representation of this age group in the Netherlands. The Youth Advisory Board has the task of advising on (1) the relevance of the studies; (2) the impact of the studies; (3) the dissemination of the findings.
