Study Summary
The Pilot Test (AKA Study B) will entail a pilot randomized, controlled trial (RCT) of an mHealth behavioral intervention, LetSync, with 80 couples (N=160) to assess its acceptability, feasibility, and preliminary impact on retention in care and ART adherence as measured by antiretroviral concentrations in hair. Participants in the intervention arm will use LetSync v1.0 for 6 months and provide acceptability and feasibility data. In the ensuing 2 months, the investigators will make refinements based on participants' data to produce LetSync v2.0. Then, participants in the waitlist-control arm will receive LetSync v2.0, use it for 6 months, and provide acceptability and feasibility data. The intervention arm will continue using LetSync v1.0, for a total of 14 months. Based on acceptability and feasibility data from waitlist control arm participants between T3 and T4, the investigators will develop LetSync v3.0, which will be used for efficacy testing in a full RCT trial in the future.
Primary Outcome
The investigators will use self-collected urine samples as another objective measure of drug adherence for participants living with HIV. The investigators will mail participants a urine sample collection kit with necessary supplies and detailed instructions via online demonstration video. Participants will self-collect and administer the urine sample and send a photo of the results to study staff. Urine test results were collected between baseline (T0) and 8 months (T4) as proportion of samples
