YouTHrive (YT) is a two-arm randomized control trial (RCT) to test the efficacy of an adapted version of the Thrive With Me (TWM) intervention for youth living with HIV (YLWH). In the RCT, intervention participants will have access to the full YouTHrive (YT) website- a mobile-enhanced private social networking website aimed at improving medication adherence for YLWH. The investigators will enroll up to 58 YLWH for formative work on YT, and 350 YLWH (15-24 years old) of all genders with a detectable viral load (VL) across six cities and randomize them to either the intervention condition or control condition. Assessments will be collected at baseline, 5, 8, and 11-month follow-up.
