Who could benefit from this research

Could help

Ideal participants are adults 21+ who identify as MSM and are interested in doxycycline-PEP and AI-based health support.

Less likely to help

Participants unlikely to benefit include those not at risk for bacterial STIs or not interested in doxycycline-PEP or AI-driven counseling.

What this research studies

This project develops SAI, an AI-powered chatbot that uses motivational interviewing techniques to tailor STI risk education and promote doxycycline post-exposure prophylaxis among MSM. The study will customize its conversations based on risk level and readiness to change, then test the chatbot in a small open-label pilot with 25 adult MSM recruited online, gathering data on accuracy, usability, and satisfaction. If promising, the team will refine the tool and explore broader feasibility for scaling AI-assisted STI prevention. The goal is to make evidence-based, accessible guidance more available without requiring frequent in-person visits.

Why it matters

Potential benefit: If successful, this chatbot could help more MSM prevent bacterial STIs with doxycycline and reduce HIV transmission through improved prevention conversations.

How similar studies have gone: Previous behavioral interventions for STI prevention have shown benefits; this study explores a novel AI-based delivery of such support.
