Sponsor's own description
This cluster randomized controlled trial evaluated the effectiveness of an 8-week, school-based behavioural intervention grounded in the Multi-Process Action Control (M-PAC) framework in promoting interruption of sedentary behaviour during school breaks among adolescents. Twelve primary and secondary schools in China, were recruited and randomly allocated (at the school level) to either an intervention group or a control group to minimise contamination and support pragmatic delivery within the school setting. Schools assigned to the intervention group implemented a multi-component programme comprising educational materials, teacher-delivered guidance, peer reminders, and health lectures, whereas control schools continued their usual routines without receiving intervention materials. The primary outcome was interruption of sedentary behaviour during school breaks assessed using self-reported measures. Secondary outcomes included physical activity levels, emotional and behavioural problems, executive function, and psychological factors related to behaviour regulation, such as motivation, planning, and habit. Findings from this trial are intended to inform the development and implementation of feasible, theory-informed school strategies to reduce sedentary behaviour during school breaks.
