La fidélité d’implantation d’un programme probant au-delà de son implantation initiale : l’exemple de Ces années incroyables en protection de l’enfance de 2003 à 2013

This article presents a study describing the fidelity of implementation of an evidence-based program and its evolution over a period of 10 years. From this study, the authors establish links between the implementation of programs, their effects, and their sustainability and discuss some of the issues surrounding the measurement of fidelity of implementation. This discussion addresses elements that may influence the fidelity of implementation and the sustainability of the studied program, including adaptations made to it. The advantages and limitations of using a quantitative approach to the evaluation of implementation to produce a portrait of implementation are also presented.
