Summary
This study investigated web-based physical activity interventions. Adding video coaching to tailored advice improved engagement and outcomes, offering a cost-effective approach for public health.
Area of Science:
- Public Health
- Behavioral Science
- Digital Health
Background:
- Effective population-based physical activity interventions are needed.
- Web-based interventions offer a scalable and cost-effective platform.
- Personalized advice enhances engagement, but the impact of video coaching is unclear.
Purpose of the Study:
- To determine the effectiveness of a web-based physical activity intervention with and without video coaching.
- To compare outcomes against a control group.
- To assess engagement, retention, satisfaction, and physical activity changes.
Main Methods:
- Randomized controlled trial with three groups: tailoring + video-coaching, tailoring-only, and wait-list control.
- Intervention: computer-tailored web-based program ('My Activity Coach') with optional video coaching sessions.
- Outcomes assessed at week 9, and 6 & 12 months post-baseline using AAQ, SF-12v2, and website analytics.
Main Results:
- (Results not yet available in the abstract)
Conclusions:
- Findings will inform the feasibility and effectiveness of online video coaching for physical activity.
- This approach may enhance intervention effectiveness cost-efficiently.
- Results will guide future web-based physical activity intervention development.
