NCT ID: NCT04166851
Last Updated: 2024-10-22
Results Overview
Questions on willingness to take PrEP. Participants will be asked, "Suppose that PrEP is at least 90% effective in preventing HIV when taken daily. How likely would you be to take PrEP if it were available for free?" with responses ranging from "Extremely unlikely-1," "Somewhat unlikely-2," "Somewhat likely-3," "Extremely likely-4." The mean of the changes between baseline and after participants reviewed the messages was calculated.
