Brief Summary
The goal of this observational study is to learn about awareness around PrEP use and adherence, condom use, sexual risk-taking behavior, and substance-using behaviors in men having sex with men. The main objective is to study a prospective cohort of MSM in Atlanta, Chicago, and San Diego to understand men's strategies to prevent HIV/Sexually Transmissible Infections (STIs), including PrEP use and adherence, condom use, sexual risk-taking behavior, and substance-using behaviors Participants will complete:
- Quantitative surveys quarterly
- HIV/ STI testing every 6 months
- Qualitative assessments: focus group discussions and in-depth interviews

Outcome Measures
Primary Outcomes (4)
Monitoring Measure: Survey reports
As a prospective observation cohort study, a primary purpose of this study is to monitor real-world, community- (non-clinic) -based HIV prevention behavior (PrEP use/adherence, condom use/adherence), including uptake and transitions among prevention modality (condom, daily oral, episodic oral, long-acting injectable) in an effort to identify patterns and gaps in HIV protection in order to develop more effective messaging to close those gaps. Rapid reports to Centers for Disease Control and Prevention (CDC) after each wave of data collection will summarize gaps in prevention and recommend the most advantageous messages to address gaps.
3 months, 6 months, 9 months,12 months,15 months,18 months
Change in condom and PrEP use and adherence based on messages for current PrEP users
The purpose of Qualitative assessments; Focus Group Discussion is to understand men's awareness of PrEP messages, preferences for PrEP messages, and perceived impact/efficacy of HIV prevention and PrEP messages
3 months, 6 months, 9 months,12 months,15 months,18 months
Change in condom and PrEP use and adherence based on messages for current non adherent PrEP users
The purpose of Qualitative assessments; Focus Group Discussion is to understand men's awareness of PrEP messages, preferences for PrEP messages, and perceived impact/efficacy of HIV prevention and PrEP messages

Study Arms (1)
MSM using or not using Pre-exposure prophylaxis
60% of MSM using PrEP at baseline in Atlanta, Chicago, and San Diego to develop knowledge around PrEP use and adherence, condom use, sexual risk-taking behavior, and substance-using behaviors. 40% of MSM not using PrEP at baseline in Atlanta, Chicago, and San Diego to develop knowledge around PrEP use and adherence, condom use, sexual risk-taking behavior, and substance-using behaviors.
Interventions
Quantitative surveys will be conducted through Alchemer, a HIPPA-compliant online survey system previously used by our group in collaborative research with CDC and supported by the Emory University Center for AIDS Research (CFAR). Surveys will be optimized for participants to take them through a personal computer, mobile phone, tablet, or the SMART study app. For participants who do not have any of these devices or prefer not to take the survey from their device, each city will have a research space where participants can schedule a convenient time to take the survey on a computer or tablet that the study will provide for that purpose.
The research team has developed and validated procedures for self-collection of specimens for testing for STIs (syphilis, urethral, rectal, and pharyngeal gonorrhea/chlamydia) and HIV self-testing. All participants will be mailed self-collection kits to provide samples for STIs (urine, rectal swab, and pharyngeal swab for gonorrhea/chlamydia; dried blood spot (DBS) for syphilis testing) and HIV (HIV 4th generation testing on DBS specimens in a CLIA-certified laboratory). Participants will be asked to collect specimens for their STI and HIV testing (every 6 months) and return them to Molecular Testing Labs. For participants who prefer in-person procedures, they will meet study staff who will provide them with the STI and HIV self-collection kit and instructions and provide a room for participants to collect their specimens.
Focus group discussions (n=up to 48 men for 3 qualitative assessments; total n=up to 144 men) as a part of the study consisting of 9 to 12 focus group discussions (FGD) with an average of 8 (range 3-10) participants in each (3 per city). These focus groups will be conducted once during the first year of the study. FGD will be conducted by a trained moderator using a semi-structured interview guide developed in collaboration with CDC scientists. For the FGD, in each city, there will be one FGD with men who have never used PrEP, one with men who are using PrEP and report no adherence issues, and one with men who are currently using PrEP or used PrEP previously and report sub-optimal adherence. In-Depth Interviews (IDIs) A series of 90 in-depth interviews (same n=up to 45 men for each of 3 qualitative assessments) will be conducted over 18 months: up to 45 IDIs each 6 months apart, with up to 15 IDIs per city each wave.
Eligibility Criteria
Primary recruitment sources will be through online targeted advertisements to adult men in the three metropolitan areas (Atlanta, Detroit, and San Diego), including social media channels, such as Facebook, Instagram or Snapchat, Grindr, and other dating apps. Additionally, recruitment will be done through referrals from local clinics and community-based organizations. These organizations may provide palm cards or QR codes for interested participants to reach the eligibility screening survey.

- Access Criteria
- Investigators will share data with researchers who provide a methodologically sound proposal. Proposals should be directed to the PI. In order to gain access, data requestors will need to sign a data access agreement
The investigators plan to share individual de-identified participant data (including data dictionaries). Individual participant data that underlie the results reported in the primary publication, after deidentification (text, tables, figures, and appendices) will be shared.
