Effects of Streak-Based Versus Tally-Based Feedback on Daily Lesson Completion During a 30-Day Digital Health Challenge

NCT07220044 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 7004

No results posted yet for this study

Summary

The study will test two interventions for increasing engagement with a target behavior, delivered via a digital web application that participants can access using their phones or computers. For example, in the streak group, users would see how many consecutive days they have completed daily lessons and will be encouraged to extend their streak. In the tally group, participants will see how many cumulative days they have completed daily lessons and will be encouraged to extend their tally.

Interventions for increasing engagement with a target behavior

The study will test two interventions for increasing engagement with a target behavior, delivered via a digital web application that participants can access using their phones or computers. For example, in the streak group, participants would see how many consecutive days they have completed daily lessons and will be encouraged to extend their streak. In the tally group, participants will see how many cumulative days they have completed daily lessons and will be encouraged to extend their tally. The investigators are interested in whether people complete more daily lessons when a 30-day health challenge app provides daily feedback on their consecutive lessons (each comprising two multiple-choice questions) completed (i.e., "streaks") vs. when it provides feedback on their cumulative lessons completed (i.e., "tallies").
