Exploring the Effect of Sharing Common Facebook Friends on the Sexual Risk Behaviors of Tinder Users.

An increasing number of young adults are using online dating sites and mobile apps. The "common connections" feature on Tinder displays mutual Facebook friends between users and might serve as an unintentional validation of a user's character. This study investigates condom use differences between partners met via mobile dating apps or in-person; and if the "common connections" feature affects the perceived sexual risk Tinder users have toward partners met online. College students who met a partner online or in-person in the past year were recruited from a large metropolitan university to complete an online survey. Participants answered questions about sexual risk behavior, condom use, Tinder use, and the effect "common connections" could have on sexual risk behaviors. The likelihood of condomless vaginal sex was no different if participants met their partner through an app or in-person. Among a subset of participants who reported using Tinder, having "common connections" with a potential date decreased the likelihood that they would talk to their date about HIV (p = 0.004) or STI testing (p = 0.001). The "common connections" feature on Tinder might influence sexual decision-making because users are able to evaluate potential dates based on their social network. Our findings suggest that Tinder users may (1) perceive partners with whom they share "common connections" as familiar or "safe," which may give users a false sense of security about the sexual health risks that a potential date may pose or (2) be hesitant to discuss sexual health matters with partners who are within their sexual network due to fear of potential gossip. Both lines of thought may reduce safer sex behaviors among sex partners who meet on Tinder.
