Trial Outcomes & Findings for Reminders Through Association & Prescription Adherence (NCT NCT03697083)

Results Overview

At the beginning of the study, participants indicate the date they plan to pick up their prescription. Participants are later asked to text a picture of their prescription receipt to the experimenter after they complete the prescription reminder program. The receipt must satisfy three criteria: 1. The receipt must show that a prescription was purchased. 2. The receipt must show the date of purchase. This date of purchase must match the participant's intended pick up date. 3. The participant must write the word "End" on their receipt. Upon receiving the picture text, one research assistant will verify that the image of the receipt satisfies all three criteria. the investigators' primary dependent variable is binary taking the value one if the participant sends a picture of their receipt to the investigators that satisfies all criteria stated above and taking the value zero if otherwise.

Participant milestones
Measure	Reminders Through Association Arm participants will be prompted to think of a reminder cue that will help them remember to pick up the prescription. Reminders Through Association: Participants receive 8 text messages asking them to think of a reminder cue that will help them remember to pick up the prescription and use the cue.	Active Control Arm Participants will be asked to think about where they will store their prescription. Active Control: Participants receive 8 text messages asking them to think of where they plan to store their medication once they pick it up and to think about that location on their intended date of pickup.	Baseline Control Arm Participants are thanked for enrolling in the reminder program. Baseline Control: Participants receive 1 text message thanking participants for enrolling in the reminder program. Participants are not contacted further.
