Strengthening adolescents' critical health literacy and scientific literacy to tackle mis- and dis-information. A feasibility study in Switzerland.

Objectives: We aimed to develop and test the feasibility of a critical health literacy (CHL) and science literacy (SL) training course targeting secondary school students in Switzerland.

Methods: Using a community-based participatory approach, we developed a two-block training program, the first centered on argumentation skills and the second on scientific skills. We combined an ex-cathedra and a flipped-classroom approach, providing students with a deep understanding of CHL and SL concepts and the translational capability of implementing theoretical notions to real case scenarios.
