Summary
The Raising Awareness of Physical Activity (RAW-PA) study found wearable technology was acceptable to adolescents but engagement was low. Future research should explore strategies to improve adherence and scale up interventions for increasing physical activity.
Area of Science:
- Public Health
- Adolescent Health
- Behavioral Science
Background:
- Wearable technology and digital resources can increase adolescent physical activity.
- Real-world implementation of these interventions remains largely unexplored.
- The Raising Awareness of Physical Activity (RAW-PA) study aimed to address this gap.
Purpose of the Study:
- To evaluate adolescents' and teachers' perceptions of the RAW-PA intervention.
- To assess program acceptability, feasibility, perceived impact, and adolescent engagement.
- To explore the potential for future large-scale implementation of the intervention.
Main Methods:
- A 12-week cluster randomized controlled trial involving inactive adolescents in socioeconomically disadvantaged schools.
- Intervention included a Fitbit Flex, app, weekly challenges, digital resources, and alerts.
- Mixed methods evaluation using surveys, focus groups, and interviews to assess perceptions and engagement.
Main Results:
- The RAW-PA intervention demonstrated good acceptability among adolescents and teachers.
- Adolescents found the intervention content and Fitbit easy to use, perceiving increased motivation and awareness.
- Engagement declined over time, with low daily Fitbit wear post-intervention; school policies posed implementation barriers.
Conclusions:
- The RAW-PA intervention was acceptable to adolescents and teachers, with feasible delivery noted.
- While short-term motivational benefits were perceived, adolescent adherence and engagement were low.
- Further research is needed to enhance engagement strategies and system-level integration for wearable technology interventions.
