Summary

This study tested two ways to encourage daily lesson completion in a 30-day digital health challenge. Over 7,000 adults used a web app where one group saw their streak of consecutive days and the other saw their total tally of completed days. The goal was to see which feedback style led to more lessons finished.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If it works, this could help design better digital health programs that keep people engaged and completing daily tasks.
What could go wrong
This is a completed behavioral study, not a treatment trial. Results may not apply to other populations or longer timeframes.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
