This research aims to evaluate several low-cost behavioral strategies designed with user input to encourage adults at higher risk of HIV exposure in rural Kenya and Uganda to retest for HIV. Enrolling 30,000 to 40,000 participants aged 15 and older, the study focuses on improving early disease detection and preventing further transmission by promoting repeat HIV testing. Participants will be randomly assigned to one of up to 12 groups receiving different interventions, such as video messages and SMS reminders based on various motivational themes like risk assessment, community benefits, social norms, and goal-setting. One group will receive a small financial incentive to encourage retesting, while another will receive standard care messaging. The interventions are delivered at baseline and followed up with reminders around 8 and 11 weeks later. Throughout the study, participants will be monitored for HIV retesting uptake measured 3 to 6 months after enrollment. Researchers will collect data to assess which strategies most effectively increase retesting rates and also track secondary outcomes like PrEP uptake. Participation includes initial visits, message delivery, and follow-up assessments, with the total involvement spanning at least 3 to 6 months.
