Individual study participant
The study population consists of men aged 18 years and older residing within the AHRI HDSS in uMkhanyakude district, KwaZulu-Natal, South Africa. Participants were drawn from a parent HIV prevention trial and were eligible if they reported alcohol use, were living without HIV, and were sexually active during the parent trial.
Demographic and behavioral data, choice responses from the DCE, individual-level preference utilities
Participants were identified from a parent HIV prevention trial conducted within the AHRI Health and Demographic Surveillance System. Eligible participants were drawn from the trial registry and approached by trained research staff for participation in the discrete choice experiment. Recruitment was conducted in person within the study area, and participants completed the survey at a time and location convenient to them. A total of 185 participants completed the discrete choice experiment.
