 Follow-up Protocols and Data Collection Once a month for the 6 month intervention period, participants in the intervention groups will receive a phone call from study staff to reinforce intrinsic motivation for improved glycemic control. At months 3, 6, and 12, participants PWDs in the control and intervention group will receive a reminder that the A1c test is due via phone, mail, and text message. At months 3 and 6, the intervention team will also receive a message via phone, mail, and text about the deadline for an in-person incentive payment. In addition, intervention participants PWDs who attain target A1c levels will receive the appropriate monetary incentives based on their new A1c levels and through participation in the lottery. Compensation and incentives will be delivered at the time of testing. At the 6 month visit, all study subjects in both groups will be administered an abbreviated version of the baseline survey. At this point the financial incentives will be withdrawn and the IM, reminder, and generic text messages will stop for the intervention arm, who, like the control arm, will only receive reminder messages for clinic visits to get A1c tested A1c testing will only be completed with PWDs in the control and intervention groups. At 12 months, all PWD and STM participants will complete a final survey. In the event the investigators are unable to reach the study participants, the investigators will obtain alternate contact information during study enrollment for all participants using a locator form. This form will be stored separate from the study participants data. This will help to increase retention over the course of the study, and the investigators will update contact information regularly via the text messages. Once the 12-month study visit has been completed, the locator form will be destroyed.
