INcentives and ReMINDers to Improve Long-term Medication Adherence

The study will test the feasibility and acceptability of using text messages and behavioral economics-based incentives to support anchoring Anti-Retroviral Therapy (ART) adherence to an existing routine in order to improve long-term ART medication adherence. The intervention phase of the three-phased study will constitute the pilot RCT. A sample of 150 clients who have initiated ART in the preceding three months will be randomized to either usual care (C = 50) or one of the two INMIND intervention groups (daily text message reminders with or without incentives) for three months (T1 = 50; T2=50). Subsequently, behavioral persistence will be evaluated for six months post-intervention. Assessments will be conducted at baseline, month 3, and month 9. The primary outcomes are 1) electronically measured mean medication adherence during the intervention and 2) six months post intervention, along with 3) timeliness of medication adherence during the intervention and 4) six months post-intervention.
