A randomized three arm control trial to examine the efficacy of two distinct apps (LYNX and MyChoices) developed for young men who have sex with men (YMSM) compared to standard of care (SOC) information about HIV testing and PrEP (Pre-Exposure Prophylaxis).

COMPARE is part of the iTech NIH U19, which has an overall goal to develop innovative technology-focused interventions addressing the HIV prevention and care continuum for youth. In years 1-2 of the iTech grant, the investigators optimized and pilot tested using a similar study design and identical study outcomes, two distinct mobile apps called LYNX and MyChoices. Each app is designed to increase HIV testing and PrEP uptake among YMSM. In this study, the individual apps are being tested in this follow-on research study to evaluate for efficacy. YMSM will be randomized to receive either MyChoices, LYNX, or SOC. LYNX uses the Information-Motivation-Behavior Skills (IMB) model and is a highly interactive mobile app to promote accurate risk perception, increase HIV/STI testing, and linkage to PrEP. MyChoices is guided by the Social Cognitive Theory (SCT) model, is adapted from HealthMindr and developed using iterative feedback from youth refined to maximize acceptability among YMSM. It includes three major functions that are designed to promote self-efficacy, self-regulation, goal-setting and environmental influences to impact behavior change. The SOC includes information on HIV testing and PrEP with the provision of referrals to local HIV/STI testing and PrEP resources.

Inclusion Criteria:

• Willing and able to attend an in-person baseline study visit in one of the study site areas, or willing to attend a remote online baseline study visit

Exclusion Criteria:

• Currently enrolled in another HIV intervention study.
• Prior enrollment in an HIV vaccine trial with receipt of experimental vaccine product.
• Enrollment in Aims 2 and 3 of the prior MyChoices (UNC IRB# 17-0256) or LYNX (UNC IRB# 17-0170) studies
• Any medical, psychiatric, or social condition or other responsibilities that, in the judgment of the investigator, would make participation in the study unsafe, complicate interpretation of study outcome data, or otherwise interfere with achieving the study objectives.
• Not willing and/or not able to download the MyChoices and LYNX apps onto their phone

Raw data will be available to outside individuals through contacting the multiple principal investigators (MPIs) at two different times. The first will be after all of the baseline data is collected. The investigators will institute a concept plan process where internal study staff first have the availability to write primary papers or give presentations on particular topics. After this, if outside individuals wish to analyze data, the investigators will welcome this collaboration. A similar process will happen for outcome data; however this will not be possible until the publication and release of the outcome paper(s). Information regarding the availability of data for analysis will be listed on the MPIs' web pages. Contact information for the MPIs will be listed in all manuscripts and publications as another means to access data.
