Acceptability and Preliminary Efficacy of an Online HIV Prevention Intervention for Single Young Men Who Have Sex with Men Seeking Partners Online: The myDEx Project.

Prevention of new cases of HIV among young gay, bisexual and other men who have sex with men (YGBMSM; ages 18-24) remains a priority. We developed and pilot tested an online intervention (myDEx) using a pilot randomized trial design with 180 online-recruited single YGBMSM who reported recent unprotected anal intercourse, self-reporting as HIV negative or status-unaware, and who met sexual partners through online dating applications. myDEx participants reported higher overall satisfaction (d = 0.46) and willingness to recommend the intervention to friends (d = 0.48) than controls. myDEx participants were less likely to report foregoing condoms to achieve an emotional connection with a partner (d =0 .43), and more likely to report greater emotional regulation during their partner-seeking behaviors (d = 0.44). myDEx participants reported fewer partners with whom they had condomless receptive anal sex (d = 0.48). Our pilot results demonstrate the potential of the myDEx intervention, suggesting that a larger efficacy trial may be warranted in the future.
