Study Design. For the primary outcomes (reduction in SDUAI and increase in HIV disclosure to sex partners), the proposed online study utilizes a 2-arm RCT design, with 10 intervention video vignettes grounded in SLT/SCT, to evaluate an innovative, multisession, video-based online intervention tailored to 1,500 English- and Spanish-speaking virally unsuppressed HIV+ White, Black and Hispanic MSM. Men will be randomized to receive 10 sessions of theory-driven video treatments or "attention" video controls. Men will be classified as White, Black, or Hispanic based on self-identification, and computerized randomization will occur within race/ethnicity to assure balanced representation across the experimental arms. All participants will receive online surveys at baseline, 3-, 6-, 9- and 12-month follow-up. All participants will receive incentives after completion of each online survey.
