We examined the acceptability of Humpr - an interactive, online tool developed to educate adolescent sexual minority males (ASMM) about how to safely navigate sexual networking applications (SNA). We developed Humpr as part of a larger HIV intervention trial in the U.S. In Humpr, 218 ASMM aged 14-20 (M = 17.18) created a mock dating profile, explored simulated user profiles, learned health-related information (e.g. slang indicating HIV/STI risks and/or drug use intentions), and then gave feedback regarding acceptability of the tool. Results showed that Humpr was very well-received, with 94% overall approval rates. Reasons for liking Humpr were evenly split between liking it for educational and entertaining reasons. Participants praised Humpr for its realistic design and interactive interface that allowed them to engage and connect with the tool. The majority (61%) had used SNAs in the past, but many still reported learning something new from Humpr. Participants also appreciated the acknowledgment of SNA use in ASMM and how the education was implemented in an open and judgment-free way. Topics learned from Humpr included how to be safe on SNAs and warning signs for HIV/STI risks. Suggested areas of improvement included having an opt-out option for those who do not wish to participate for any reason (e.g. discomfort) and additional educational content (e.g. consequences of being a minor on SNAs). Taken together, the findings offer preliminary evidence for the potential educational benefits of digital tools like Humpr for ASMM with and without prior SNA exposure.
