Evaluation of Three School-based Mental Health Preventive Interventions in France

To meet adolescents' needs regarding mental health vulnerability, this study aims to propose and evaluate three original school-based preventive interventions delivered to French 13y-adolescents, with respect to their effects on mental health outcomes, as well as users' experiences of intervention, evaluated through questionnaires. Based on cognitive-behavioral therapies (CBT) techniques, these interventions target three strategic process areas: reactive adaptation, proactive adaptation, and interpersonal adaptation. Their effectiveness will be evaluated through a four-arm randomized controlled trial, conducted in an ecological context. Intra-group and inter-group comparisons will be carried out for our different variables of interest, namely targeted psychological processes, levels of distress, functional impairment, and well-being, and user experience indicators of acceptability, utility, and usability.
