Youth have been participating in co-creation sessions aimed at developing methods to establish ethical practice. More than 60 methods have been ideated of which 18 are selected by youth through dot voting. Because co-creation is a collective effort involving both youth and adults, it is important to include adult perspectives as well with regards to the added value of these methods. To this end, an evaluation session with adult facilitators was held during Health CASCADE’s Barcelona meeting in October 2023. It was a fruitful meeting in which seven colleagues participated. There were valuable observations of the methods ideated by youth, and important considerations were discussed. I am hopeful that these insights will help further improve the methods and will contribute to ethical co-creation practice in the future.
