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.

La fidélité de l'implantation d'un programme d'intervention pour des adolescentes agressées sexuellement: une mesure par observation systématique

Reported here is a first study of the implementation fidelity group intervention program for sexually abused adolescent girls, consisting of 18 sessions centered on 9 themes. Through systematic observation of the intervention protocol used with two groups of adolescents, the case study describes implementation fidelity and its evolution. Results show that the first group outperformed the second in terms of implementation adherence. Levels of participation were similar between groups but quality appears to have improved for the second group.
