The proposed study is a randomized controlled intervention to reduce sexual risk for HIV among HIV-negative concordant and HIV discordant gay couples. There are three arms of the study: 1) the in-person experimental condition, PRIDE, 2) the online adaptation of the experimental condition, ePRIDE, and 3) the time- and attention-matched in-person control condition, Men's Health. Participants (N = 300 couples) will be randomized equally into one of the three study conditions and assessed via surveys at baseline and at 3-, 6- and 9-months after completion of the intervention sessions.
