The French Public Health Society (SFSP) and the National Federation for Health Education and Promotion (FNES) are leading the discussions within the national Capitalization Working Group. This group operates within the framework of the Public Health Initiative for Interaction between Research, Intervention, and Decision-Making (InSPIRe-ID), coordinated by the Directorate General for Health. The initiative led by the National Capitalization Working Group identifies innovative actions and organizes their capitalization, supporting the facilitators and project leaders involved; because it aims to “transform practical knowledge into shareable knowledge,” capitalization undeniably emerges as one of the potential drivers for building a national health promotion policy.
