Mobile Messaging Intervention to Present New HIV Prevention Options for Men Who Have Sex With Men...
Human Immunodeficiency VirusThe study will evaluate the use and effectiveness of mobile-messaging platforms as a public health strategy for improving sexual health outcome measures among men who have sex with men (MSM) by determining whether exposure to the message-delivery platform results in improvements in participants' self-reported sexual health and prevention behaviors, beliefs and attitudes. The study will enroll men into a randomized controlled trial. Participants randomized to the messaging intervention will have access to a smartphone-based messaging platform for three months while those assigned to the waitlist group will be offered access to the messaging platform after all follow up is complete. Participants will complete surveys at baseline, after the end of the 3 month intervention, and follow up surveys 6 and 9 months after the baseline survey.

Pre-exposure Prophylaxis (PrEP) at Home
HIV/AIDSThis study is a randomized clinical trial of PrEP@Home, a home care system for Human Immunodeficiency Virus (HIV) Pre-Exposure Prophylaxis (PrEP). Individuals entering into PrEP care at an initial in-person study visit will be randomized to the PrEP@Home system for home-based PrEP care follow-up visits or to the control standard of care for clinic-based follow-up visits. The primary aim of this study is to assess protective levels of PrEP medication for the intervention arm compared to the control arm.

We Prevent: A Dyadic Approach to HIV Prevention and Care Among Young Male Couples
HIV/AIDSWe Prevent seeks to develop and pilot test a developmentally-appropriate relationship skills session as an addition to the current Couples HIV Testing and Counseling (CHTC) intervention for young gay, bisexual and other men who have sex with men (YMSM). This project involves three phases to develop and pilot test the intervention. Phase I collected brief quantitative survey data, in-depth qualitative interview data, and cognitive interview data from YMSM and feedback from a technical expert group (TEG) to develop and refine the two-session intervention. Phase II involved conducting a one-arm pilot of the intervention condition to further refine the intervention content with a sample of 12 YMSM (6 dyads). Phase III involves conducting a randomized controlled trial (RCT) comparing the relationship-focused intervention to a control condition, which is HIV Testing, Counseling, and Referrals (CTR) alone with a sample of 320 YMSM.

Increasing PrEP Among African Americans in Louisville KY
HIV/AIDS PREVENTIONThis study evaluates the effectiveness of a multifaceted strategy to increase pre-exposure prophylaxis (PrEP; a medication regimen to reduce HIV risk) uptake among high risk African Americans in Louisville, KY. We will do this by 1) implementing a media campaign to raise awareness about PrEP, 2) providing PrEP education to medical personnel who can prescribe PrEP, and 3) partnering with AIDS service organizations to improve outreach and linkage to PrEP services.

A Field Experiment to Assess the Demand for HIV Self-Tests in Zimbabwe
HIV/AIDSThis study is a field experiment in peri-urban and rural communities near Harare, Zimbabwe, that seeks to estimate the likelihood that individuals will purchase HIV self-tests under various pricing and distribution strategies. About 4,000 adults will be randomly selected, administered a short questionnaire, and given vouchers that will offer them HIV self-tests at randomly allocated prices and distribution sites. The study will also test whether the provision of HIV self-tests can be targeted more cost-effectively to reach high-risk persons and non- recent testers. Last, the study will explore whether demand for repeated HIV self-testing is contingent on the price offered initially.

HOme-based SElf-testiNG - a Cluster Randomized Controlled Trial in Rural Lesotho (HOSENG)
HIVHIV/AIDSThis cluster-randomized trial aims to evaluate the efficacy of the use of oral HIV self-testing (HIVST) among individuals who are absent or who decline HIV testing during home-based HIV testing

Developing and Examining Evidenced-Based HIV Testing Messages
HIV/AIDSThe goals of this study are to: Develop a HIV test message tailored for African American women. A generic non-tailored message will be developed as well for comparison. A third group will be included that will not be exposed to any message at all. Test the effectiveness of both messages on reported future intentions to get tested for HIV and HIV test behavior at 3 month follow up.
