L'étude des mécanismes de changement, une avenue de recherche prometteuse pour optimiser les programmes de traitement destinés aux jeunes en difficulté: enjeux conceptuels et méthodologiques

To date, many treatment programs for troubled youth have been shown to be effective on the basis of rigorous studies, but the processes responsible for the success of these programs are still unknown. This article presents the study of mechanisms of change as a promising research avenue for optimizing treatment programs based on their capacity to identify why, how, for whom, and in what contexts they work best. The theory-driven approach to program evaluation is proposed as a useful framework to guide the identification of potential mediating and moderating variables in treatment outcomes.
