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 due to its capacity to identify why, how, for whom and in what contexts they work best. The theory-driven approach to program evaluation is proposed thereto as a useful framework to guide the identification of potential mediating and moderating variables of treatment outcomes. Finally, conceptual and methodological clarifications are given, as well as some examples based on treatment programs for children with problematic sexual behavior or juvenile sex offenders.
