Randomized Controlled Trial of Situated Optimal Adherence Intervention Estonia (sOAI Estonia) Among Persons Living With HIV/AIDS (PLWHA) on Antiretroviral Therapy (ART) in Estonia

Situated Optimal Adherence Intervention consists of 3 individual sessions (during consecutive medication pick-up visits to the clinic) -- patient-centered, non-judgmental, Motivational Interviewing- and theory-based, semi-structured, brief, candid conversations with a trained clinical care nurse using the Next Step Counseling approach. The intervention targets: accurate information about ART (mechanisms of HIV and antiretrovirals) and the development of mental imagery around it; promotion of perceived sense of ease and efficacy in working the ART regimen into the context of one's daily life and circumstances that may challenge drug use persistence; identification and refinement of skills that promote ease of adhering to one's ART regimen across the diverse and challenging contexts.
