Hypothesis
How does program exposure differ across face-to-face, internet-mediated, and internet-only intervention delivery modes?
Conclusion
The internet groups were as effective as the face-to-face delivery mode in engaging participants in the program material.
Supporting Evidence
- Participants in the internet-mediated and internet-only groups were more likely to achieve at least 75% program exposure compared to the face-to-face group.
- High physical activity self-efficacy was associated with a greater likelihood of achieving 75% program exposure.
- Drop-out rates were similar to other physical activity interventions delivered face-to-face.
Takeaway
This study looked at how people used different ways to learn about being active, like in-person classes or online programs, and found that online programs worked just as well for getting people involved.
Methodology
Participants were randomly assigned to one of three groups: face-to-face, internet-mediated, or internet-only, and their program exposure was tracked through attendance and website usage.
Potential Biases
Participants may have been more motivated to change their behavior than the general population.
Limitations
The study sample was predominantly female and self-selected, which may limit generalizability.
Participant Demographics
Predominantly women (83.3%) with a mean age of 38.4 years and a mean BMI of 32.2.
