AI Chatbot Delivers MI-Aligned PrEP Counseling
8.1
Researchers at Brown University developed CHIA, an AI chatbot built on GPT-4o to deliver motivational interviewing–aligned counseling for HIV preexposure prophylaxis (PrEP), and conducted internal usability testing from March 10–April 28, 2025. Across 296 responses (145 English, 151 Spanish), CHIA scored high on up-to-dateness (mean 4.6), trustworthiness (4.5), and accuracy (4.4), but Spanish responses lagged significantly.
Key Points
- 1Demonstrates CHIA delivered MI-aligned counseling using GPT-4o, tested March 10–April 28, 2025 (296 responses).
- 2Shows strong overall quality—up-to-dateness 4.6, trustworthiness 4.5, accuracy 4.4—indicating reliability.
- 3Highlights Spanish performance gap; practitioners should validate and localize Spanish outputs before deployment.
Scoring Rationale
Strong novelty and clinical relevance, but limited to internal usability testing and needs improved Spanish performance.
