Hypothesis
The percent weight loss difference between conditions at 6 and 12 months will be less than 2% and the asynchronous condition will cost less to deliver per pound lost.
Conclusion
Asynchronously delivered remote interventions may be as effective as synchronous ones and more sustainable.
Supporting Evidence
- Remote interventions can be delivered synchronously or asynchronously.
- Asynchronous interventions may be more sustainable due to their flexibility.
- Previous studies have shown that technology-delivered interventions can be effective for weight loss.
- Participants in asynchronous interventions can engage at their convenience.
Takeaway
This study is looking at two ways to help people lose weight online: one where everyone meets at the same time and one where they can join in whenever they want.
Methodology
Randomized noninferiority trial comparing synchronous and asynchronous lifestyle interventions with 328 participants.
Potential Biases
Potential bias due to exclusion of non-Facebook users and reliance on self-reported weight data.
Limitations
The study may not be generalizable to non-Facebook users and may attract predominantly white and female samples.
Participant Demographics
Participants must be aged 18-65, with a BMI of 27-45, and must use Facebook at least 5 days a week.
