摘要

Aim

We aimed to examine the feasibility of integrating systems science tools in physical education to promote social support for physical activity and to reduce screen time among adolescents through a social network-based intervention.

Methods

A sequential exploratory mixed-methods design was employed. The qualitative phase consisted of the development of group model building sessions, incorporating principles of community-based participatory research. The quantitative phase included social network analysis to identify key actors providing social support for physical activity and screen time, followed by a quasi-experimental intervention in two physical education classes (n = 69). Lessons were designed according to the cooperative learning pedagogical model to foster social support for physical activity and screen time reduction. Recruitment, intervention fidelity, acceptability, and potential barriers and facilitators were evaluated.

Results

The recruitment rate for the group model building was 80%. The intervention retention rate was 91%, and implementation acceptability according to the teacher was very good, with approximately 80% of students reporting that they liked the intervention activities. Observation indicated adequate participation in the group model building session. The resultant causal loop diagrams illustrated factors influencing social support provision, which informed and complemented the content of the physical education classes. Social network analysis identified key social support providers, who played a central role in the intervention.

Conclusion

Integrating systems science tools with physical education is feasible. Organizational constraints within physical education class, time limitations, and the complexity of implementing participatory systems approaches are challenges that should be addressed in future interventions.
