In this study, data on opening of the pill bottle will be transferred wirelessly from the bottle cap and a text on adherence sent to the phone. This developmental project will adapt and refine a smartphone app/game to include content consistent with the Information-Motivation-Behavioral Skills (IMB) Model. Creation and adaptation will occur from in-depth interviews with YLWH on ART (n=25) and an open trial of the Intervention (n=20). While gaming, participants will experience absorbing action-oriented adventures that increase information about their health (e.g. knowledge about HIV treatment), improve motivation (e.g. action-figures experience health benefits of adherence), and build skills (e.g. utilize clinicians as partners). A small randomized controlled pilot study (24 weeks) among 60 YLWH will examine the preliminary efficacy of the IMB Gaming Adherence Intervention (integration of the smart cap with the IMB informed app/game) compared to a comparison group who receive the smart cap and smartphone but no IMB game, on adherence and biological measures.
