Wellth + Habit Training
Participants in the control group will not receive additional adherence reminders or financial incentives during the 9-month study.
Participants will be eligible to receive $30 at the end of three consecutive 30-day periods ($90 in total) if they demonstrate complete medication adherence through the Wellth app (i.e. taking a daily picture of their pills in their hand and submitting it through the Wellth app). Photos must be submitted within a 4-hour window around a specific time of day chosen by the participant and set at the start of each 30-day period. They will lose $2 (from their $30 total) for every day they miss a medication check-in within their pre-set 4-hour window with the Wellth app. The Wellth app will also provide reminders at the end of the day if participants have not yet completed their daily check-in.
Participants will also be eligible for $30 at the end of three consecutive 30-day periods ($90 in total) if they submit daily evidence of their medication adherence habit using the Wellth app (i.e. one photo that provides evidence of pill-taking and one photo that provides evidence of their contextual cue, which participants will select and specify on their comprehension survey at the start of the study). Similar to T1, participants will lose $2 (from their $30 total) for every day they miss a check-in with the Wellth app within a 4-hour window around the time of day of their choosing at the start of each 30-day period. Participants will not have to pay money, i.e. they lose $2 per missed check-in from the $30 of incentives until their incentives equal $0. Thus, participants will be ineligible for any financial incentives if they miss more than 15 days in a 30-day period, where this group's check-in includes one photo of pill-taking and one photo of their contextual cue.
