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.
Primary Outcome
The key dependent variable is a person's total number of lessons completed during the 30-day Health Daily program. Participants can only complete a given day's lesson on that day; a lesson is only considered complete if both questions that comprise the lesson are answered.
Interventions
- BEHAVIORAL Interventions for increasing engagement with a target behavior
