Preferences for Long-Acting HIV Pre-Exposure Prophylaxis (PrEP) Formulations among East and Southern African Women – Evidence from a Discrete Choice Experiment (DCE)
Enrolled HIV-uninfected cisgender women from 6 African countries, sexually active and 16–30 years old.
Women were offered PrEP at each visit
DCE survey administered at enrollment and month 1 with 16 randomly assorted choice sets assessing 5 PrEP attributes
DCE analyzed using Sawtooth software
Preference weights: relative desirability of an attribute level with higher numbers indicating a greater preference, computed using hierarchical Bayesian model
Importance scores: relative importance across the 5 attributes (higher scores indicate greater importance)
