Capitalisation as a boundary object in intervention research, serving knowledge production and mobilisation.

Knowledge transfer is a key issue in population health intervention research (PHIR). In order to foster ownership and implementation of evidence-based data by decision-makers and field workers, it is important to produce more knowledge based on the actual practices of these actors. By providing a platform for field actors and mobilising a structured, qualitative approach to collect, analyse, and share field-based knowledge, Capitalisation of Experience Knowledge in Health Promotion (CEKHP) can be a valuable tool for PHIR. This article illustrates this contribution through two concrete experiences of mobilising the CEKHP approach within the framework of two projects: the PROSCeSS PHIR project (health promotion within sports clubs) and the IMPACT project (transferability analysis of the experimental primary care system for disadvantaged patients).
