Measure
Intervention
Subjects will receive an intervention based off of current evidence-based practices that will consist of activities designed to strengthen support within the couple to improve adherence to antiretroviral therapy. SMART Couples 2: The intervention will consist of 3 sessions with activities designed to strengthen communication and support within the couple to improve adherence to antiretroviral therapy and increase linkage to drug treatment services. The activities are based on cognitive-behavioral therapy. Participants' adherence will be monitored continuously through electronic monitoring devices and surveys completed at baseline and follow-up periods.
Standard of Care
Standard of Care is the comparison arm that consists of care currently provided at the AIDS Center. Subjects will receive a consultation with a healthcare provider every three months, prescription refills, and blood draws for viral load and CD4 testing. Standard of Care: Standard of Care consists of an appointment with an AIDS Center nurse at baseline and two months later. Under current Standard of Care in Almaty, no behavioral intervention is provided. Participants obtain prescription refills and give blood for viral load and CD4 tests once every 6 months.

PRIMARY outcome

Timeframe: Day 1 to Day 180 (daily)

Population: Participants analyzed included only those who were HIV-positive and who used the electronic monitoring device: 35 out of 64 in the intervention arm and 45 out of 68 in the standard of care arm. Not all participants were able to collect evaluable data using the device since there were no in-person study visits during the pandemic to help with troubleshooting.

Adherence rate is defined as the number of days the electronic pill bottle was opened to take medication (out of a total of 180 days).

SECONDARY outcome

Timeframe: 6 month follow-up

Population: Participants who had viral load testing data from the AIDS Center.

HIV viral load suppression was considered at ≤500 copies/ml in accordance with the Almaty AIDS Center testing standard. Participants were classified as virally suppressed or not based on their most recent viral load test result (at baseline and at the 6 month follow-up) obtained from electronic medical records at the AIDS Center.
