There is now a consensus on the value of relying on evidence—by incorporating both scientific knowledge and the experiential insights of professionals and users—in the field of prevention and health promotion. Evidence-based practice is thus recognized by most stakeholders and decision-makers as a means of improving the effectiveness, credibility, and transferability of prevention and health promotion interventions. The scientific knowledge accumulated over the past few decades is particularly extensive. One of the major challenges in prevention and promotion is therefore to facilitate the transfer and application of this scientific knowledge into routine practice and to overcome the many barriers and obstacles to the use of this data.
