Rapid Education/Encouragement And Communications for Health intervention components (REACH).

Component Description
Daily text message promoting self-care Every day, users receive a text message promoting self-care at a random time within their prespecified window of time.
Each week, REACHa sends 7 of these messages, consisting of 3 tailored messages addressing 1 of their 4 identified barriers to medication adherence, 1 tailored regimen-specific message, and 3 nontailored messages providing tips for diet, exercise, or SMBGb (Figure 2).
Daily text message assessing adherence Every day, users receive a text message at their prespecified bedtime asking if they took all of their diabetes medication that day (requesting a “yes” or “no” response). Users responses may trigger follow-up messages (Figure 1).
Weekly text message delivering adherence feedback At the end of each week, users receive a feedback text message based on the number of “yes” responses to the assessment text message for that week. The feedback is accompanied by an encouraging statement tailored to the number of days the participant adhered to their medication and whether the participant’s adherence improved, stayed the same, or declined relative to the prior week (Figure 2).
HbA1cc text message Participants have their HbA1c level tested upon study enrollment and receive an HbA1c text message when their result is ready. The HbA1c text message provides directions on how to access the result, either by logging on to a HIPAAd-compliant webpage hosted by MEMOTEXT or calling the REACH Helpline (Figure 2).
REACH Helpline Participants have access to the REACH Helpline, an inbound answering service hosted by MEMOTEXT. Participants call the Helpline to leave a voicemail regarding a research-related question (eg, compensation, changed phone number, accessing HbA1c test result), technical question (eg, problems receiving or sending text messages), or medication-related question (eg, how to handle side effects and/or a missed dose).
