Description of the cases included in the study.

BackgroundA smoking cessation program for adolescents, TABADO, demonstrated its effectiveness following a controlled trial conducted in 2007/2009. The program is now being scaled up nationally. In order to retain its efficacy across the diversity of contexts in the generalization process, we needed to assess the processes and mechanisms that inform its effects. Theory-driven evaluation is one approach used to address these issues. The aim of the present research is to develop the TABADO program theory. More specifically, we attempt to identify the factors and mechanisms that promote or hinder the enrollment and retention of student smokers in the program.MethodsWe conducted a realist evaluation of the TABADO program through 1) a documentary analysis to construct the initial program theory, and 2) a multiple case study (n = 10) conducted in three regions in France to test and enrich the initial theory with contextual, organizational and mechanistic components. We used the Intervention-Context-Actors-Mechanisms-Outcomes configurations to guide our analysis and to present our results.ResultsOur analysis highlighted 13 mechanisms that foster the enrollment and retention of student smokers in the TABADO program (e.g., being prepared to quit smoking, feeling encouraged in the attempt to quit smoking). To activate these mechanisms, the involvement of various actors is required (e.g., the school nurse, teachers), together with a combination of interventional and contextual factors (e.g., confidentiality, informal speaking time).ConclusionsThese findings allowed us to transform the TABADO program into a new optimized strategy, TABADO2, which is theory-based. Our research helps to explain why adolescent smokers enroll and stay in a school-based smoking cessation program. TABADO2 needs to be considered in a more comprehensive way than the original research-based TABADO, and should be tailored to its implementation context.</div
