Summary

Adolescents spend the majority of the day sedentary, especially at school whilst sitting in class and at home when performing school-related tasks. 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.

Conditions

  • Sedentary Behaviour

Interventions

BEHAVIORAL

Co-adapted intervention

An existing co-created intervention will be adapted by researchers and 7th and 8th grade pupils and teachers during 3 to 5 design sessions in both co-adaptation intervention schools.

BEHAVIORAL

Standard intervention

The existing co-created intervention will be implemented in the standard intervention schools. So, adolescents and school staff from the standard intervention schools will not be involved in adapting the intervention.
