Evaluating the Effectiveness of a Mobile HIV Prevention App to Increase HIV and Sexually Transmitted Infections (STI) Testing and PrEP Initiation Among Rural Men Who Have Sex With Men
Sponsor: Emory University
Summary
The goal of this clinical trial is to test the efficacy of a mobile app, Combine, to increase the uptake of HIV and STI testing and pre-exposure prophylaxis (PrEP) over 24 months and to assess the effects of different implementation strategies on intervention maintenance among GBMSM in rural southern United States. The main aims of the study are: * To assess the relative effects of three treatment conditions on gains in engagement in HIV prevention compared to a modified standard of care control condition * Measure and assess secondary factors affecting app implementation * Refine implementation strategies and coordinate with potential funders Participants will download an HIV prevention smartphone app and be randomly assigned to one of four groups: * Control: App access only * Self-testing: App access + ability to order HIV and STI self-test kits * Motivational interview: App access + motivational interview to develop plans to use app effectively. * Self-testing + motivational interview: App access + ability to order HIV and STI self-test kits + motivational interview to develop plans to use app effectively. Researchers will compare each of the latter three groups to the control condition to see if HIV and STI testing increase in these groups

Interventions
Combine mobile app
* HIV/STI testing: learn more about testing options; create a plan to test 1-4 times in the coming year; locate places for those tests and/or order at-home test kits; and schedule reminders for periodic testing * Pre-exposure prophylaxis: PrEP self-assessment at first app use; monthly rescreening for PrEP eligibility; recommendation for PrEP based on Centers for Disease Control and Prevention (CDC) criteria; PrEP provider locator. * Behavioral risk assessment: e.g. HIV risk behaviors; sex while drunk or high, condomless anal intercourse with a positive or unknown HIV status partner, multiple sex partners, recent STI diagnosis, use of drugs) and protective behaviors * Non-occupational post-exposure prophylaxis (nPEP): information about nPEP; self-assessment; locator; referral to PrEP for men who evaluate multiple exposures for nPEP indication * Product ordering: participants can order condoms, condom-compatible lubricants, and at-home STI specimen collection kits.
Motivational interview
The interview will be grounded in the Social Cognitive Theory of self-regulation (SCT) to reflect the underlying theory of the Combine app. It will be designed to enhance the effectiveness of the app by highlighting app features (e.g., frequently asked questions, product ordering, testing locators) and discussing strategies for following through on goals related to sexual health (e.g., creating and adhering to a testing plan)
HIV/STI testing
Participants will be able to order free HIV/STI self-test kits; they will be able to order up to two sets of kits during each of years 1 and 2 of follow-up. HIV and STI test kit orders are independent: ordering an HIV test kit does not trigger shipment of an STI kit and vice versa. When an order is placed, kits containing biospecimen self-collection tools are shipped directly to the participant along with written instructions and a link to video instructions on how to collect each of the samples (e.g., urine, rectal, blood). Return packaging is enclosed with instructions for participants to locate a drop-off location to return their samples to the lab.
