Adaptation of a digital health HIV prevention intervention for Black heterosexual couples in New York State

ABSTRACT / SUMMARY Current HIV/STI prevention interventions for Black heterosexual / opposite-sex (BHOS) couples in the US require an in-person modality and focus on specific subgroups (sero-doscordant, substance using). Digital health interventions (DHIs) may provide one solution to expand access to tailored, couples-based HIV/STI

prevention-care interventions that appeal to a wide variety of Black heterosexual / opposite-sex (BHOS) couples in the U.S. with varying vulnerabilities to HIV and other STIs. One couples-based DHI has reduced cisgender male couples’ susceptibility to HIV and other STIs. The DHI used a hybrid format with individuals first completing a sequence of pre-determined modules (i.e., HIV/STI

education, instructional videos, a searchable sexual health resources database, activities including an agreement builder) followed by completing the sequence jointly with their partner, and then ending with a finalized, comprehensive sexual agreement containing HIV/STI prevention items. To examine the acceptability

of this theoretically-driven, couples-based DHI for HIV/STI prevention, we conducted a multi-method pilot project with 28 BHOS couples in New York State. BHOS couples reported high intervention acceptability (96%), and qualitative dyadic content and thematic analysis revealed explicit recommendations to enhance

intervention relevancy for adapting the DHI to meet their specific relationship and sexual health needs. Given these preliminary findings, we propose to conduct a novel, 3-year mixed method study guided by the Couples Interdependence Theory and the ADAPT-ITT model to adapt and pilot-test this DHI to meet the

needs of BHOS couples. Dyadic data will be collected via: a) quantitative assessments at baseline, month 3 and 6; b) HIV/STI screening at baseline and month 6; c) 7 different paradata outputs (intervention use); d) individual exit interviews at month 6. Our specific aims are: Aim 1: Adapt the intervention for BHOS couples

using the APAPT-ITT model with human-centered design. Aim 2: Conduct a 6-month pilot RCT with 60 BHOS couples using a 2:2 block random allocation approach (intervention vs. 3-month, delayed control), stratified by dyad HIV serostatus (i.e. serodiscordant, seroconcordant). Feasibility will measure enrollment and retention

rates. Acceptability will leverage mixed methods from 3 data
