As high levels of sedentary time are associated with adverse health effects, effective interventions are needed. To improve effectiveness, literature recommends a co-creative approach in which adolescents and other key stakeholders (such as teachers) are actively involved in the choice and development of intervention strategies. Therefore, this project aims to co-adapt a previously co-created intervention targeting adolescents' school-related sedentary behaviour. Further, the effect of this co-adapted intervention on adolescents' sedentary behaviour and related determinants, sleep, and mental wellbeing will be evaluated via a three-arm clustered controlled trial, including a co-adaptation intervention arm, a standard intervention arm (including schools that were not involved in co-adapting the intervention) and a control arm (continuing their curriculum as usual). By comparing these three arms, the investigators can evaluate the added value of co-creation compared to not involving adolescents or stakeholders in the development of an intervention. Lastly, the investigators will conduct a process evaluation of (1) the co-adaptation approach used to adapt the co-created intervention and (2) the implementation of both the co-adapted and standard interventions. Studies that evaluate co-created interventions are scarce. However, if such interventions prove to be more effective, this approach could be promising to change adolescents' health behaviour.",[67],"Sedentary Behaviour",[69,70,71,72,73,74,75,76,77],"Adolescents","Youth","Student","School","Classroom","Sedentary behaviour","Participatory research","Co-creation","Co-adaptation","NOT_YET_RECRUITING","2025-06-23",{"date":81,"type":82},"2025-06-25","ACTUAL",{"date":84,"type":61},"2025-09-01",{"date":86,"type":61},"2026-06-30",{"name":5,"class":6}]
