Brief Summary
This study is a field experiment in peri-urban and rural communities near Harare, Zimbabwe, that seeks to estimate the likelihood that individuals will purchase HIV self-tests under various pricing and distribution strategies. About 4,000 adults will be randomly selected, administered a short questionnaire, and given vouchers that will offer them HIV self-tests at randomly allocated prices and distribution sites. The study will also test whether the provision of HIV self-tests can be targeted more cost-effectively to reach high-risk persons and non- recent testers. Last, the study will explore whether demand for repeated HIV self-testing is contingent on the price offered initially.
