Using Social Media to Deliver HIV Self-Testing Kits and Link to Online PrEP Services

The primary objective of this study is to compare the relative effectiveness of three web-based platforms: social media sites (e.g., Facebook), dating applications \[apps\] (e.g., Grindr), and informational sites (e.g., Google) to promote self-testing of Human Immunodeficiency Virus (HIV) infection among men who have sex with men (MSM) who are at increased risk of HIV exposure and/or infection. In addition, we will measure Pre-Exposure Prophylaxis (PrEP) uptake and evaluate the degree to which substance use and, separately, the participant's intention to test affect HIV self-testing and PrEP uptake. Through this research, we will also examine how participants' social media use, attitudes on HIV testing, perceptions of sexual risk behavior, medical mistrust, and stigma impact HIV testing and PrEP uptake.
