Reducing and Breaking up School-related Sedentary Behaviour Among Adolescents Using Co-creation

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.

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.
