ECHOO seeks to empower health consumers, despite their age, role, and skills, by focusing on often-overlooked placebo/nocebo effects in treatment decisions, using high-impact pedagogies. It aims to 1) empower knowledge, making accessible and transferable evidence-based placebo/nocebo concepts; 2) embed knowledge within universities’ transversal competence catalogues; 3) spread knowledge, engaging the broader community to raise awareness, competences, and skills.
