## Abstract

PROJECT SUMMARY: In Travis County, Texas, deemed a HIV geographic hotspot due to high HIV rates,
Black women are 18.4 times more likely to contract HIV compared to women of other races/ethnicities. Black
women also have higher rates of sexually transmitted infections (STIs) than other women; many STIs have no
symptoms, are undiagnosed, and are untreated. Having an STI triples one's risk for contracting HIV. In Travis
County, over 20% of women learned one year after contracting HIV that they were HIV-positive, highlighting
barriers to testing. Home HIV/STI testing has promise to increase rates of testing by circumventing barriers and
thereby reduce medical costs through early detection and care. Home HIV/STI testing is also a prime
opportunity to link Black women at high risk for HIV to pre-exposure prophylaxis (PrEP). Yet, home testing
alone may not overcome all barriers. Pairing home testing with an intervention designed to increase motivation
and overcome barriers has the most promise to increase HIV/STI testing rates. The proposed project draws on
3 components, the situated, information-motivation-behavioral (sIMB) model, mental contrasting, and
implementation intentions to develop a new, web-based intervention. This intervention is comprised of 5
sessions: 1) using the HIV/STI home testing kit, 2) mailing in the kit, 3) checking results, 4) obtaining treatment,
and 5) attending an appointment for PrEP. Each session is structured the same: information regarding the
importance of each behavior (i.e., taking the home test, mailing in the test, checking results, linkage to care,
and linkage to PrEP), motivation via mental contrasting (identifying positive outcomes and barriers to each
session) and methods to overcome the identified barriers (implementation intentions), and behavioral skills to
increase self-efficacy. The project will occur in 3 phases that coincide with the aims to develop and culturally
tailor the intervention. 1) Conduct formative research to develop the intervention. Four focus groups (n=4-6),
with 24 Black women from Travis County will explore the constructs of sIMB, mental contrasting, and
implementation intentions to develop the intervention protocol to be field tested in Aim 2. 2) Field test the
intervention. We will test the preliminary feasibility and acceptability of the intervention with 6 participants to
make any necessary adjustments for Aim 3. 3) Conduct a feasibility pilot of the intervention. We will determine
the feasibility, acceptability, and preliminary efficacy among 60 Black women in Travis County. Participants will
be randomly assigned to the intervention or a web-based educational control. We hypothesize that the
intervention will be feasible, acceptable, and demonstrate a trend toward efficacy for completion of home
testing, linkage to care, and linkage to PrEP. Follow-up web-based assessments will be administered 2-, 4-,
and 6-months after baseline. The web-based design of the intervention greatly increa...
