HIV pre-exposure prophylaxis (or PrEP) is an effective additional preventative measure for reducing the risk of HIV transmission. To address low levels of uptake, there is a need for public health interventions to increase target populations' awareness and willingness for adopting PrEP. One potential solution may be to incorporate a network intervention, which utilizes the connections between individuals to facilitate health behavior. This project examines how online networks can influence PrEP adoption intentions among gay and bisexual men through a mobile app-based experiment. In this study, participants will be randomly assigned into a social support condition or information-only control. Both conditions will involve an information component consisting messages aimed to address awareness, knowledge, and perceived barriers of PrEP adoption. However, those in the social support condition will also have an online chatting tool where they can discuss topics surrounding PrEP. The primary objective of this study is to test the effectiveness of the mobile app intervention in increasing participants' knowledge/attitudes/intentions to initiate PrEP. The secondary objective of this study is to determine the mechanism of the intervention through mediation analyses.
