Acceptability of Using Geosocial Networking Applications for HIV/Sexually Transmitted Disease Partner Notification and Sexual Health Services.

Background: Geosocial networking (GSN) app use among men who have sex with men (MSM) has presented new opportunities for increasing the reach and efficiency of sexual health interventions but also poses challenges to HIV/sexually transmitted disease partner notification. Understanding MSM's attitudes toward app-based preventive sexual health services can help inform their development and delivery.

Methods: We recruited US MSM who had met a sex partner on GSN apps in the last year to participate in an online survey assessing acceptability and preferences regarding app-based partner notification, health department presence, and sexual health services. Three app-based notification strategies were presented: sending notification messages through participant's/partner's app profile, health department app profile, or in-app anonymous messaging.

Results: Of 791 respondents, a majority (70%) preferred to be notified by their partner directly; however, most would get tested if notified by health department profile (95%) or anonymous in-app message (85%). Given the options provided, 50% preferred notifying a partner using their own profile, 26% with health department assistance, and 24% via in-app anonymous message. A majority (71%) were comfortable notifying a partner through a health department profile, and 74% were comfortable using in-app anonymous messaging. Most participants (82%) were comfortable with health departments having app profiles to provide sexual health services.

Conclusions: Our results suggest that GSN app-based partner notification and sexual health services would be used by and are acceptable to US MSM. Partnering with app companies to integrate these services and increase access to public health programs has potential to improve MSM sexual health.
