  • Description:
    iTAB is an individual-level, mobile-health intervention that uses two-way, fully automated daily personalized health promotion and “factoid” text messages to improve PrEP adherence. Participants choose messages consistent with their preferences from 440 different messages or create their own messages. Each message ends with a prompt to respond with a single letter indicating whether participants have taken or not taken PrEP. Participants receive daily messages at a personally selected time for taking PrEP. Both iTAB and the comparison (Standard of Care) group receive, at baseline visits, a brief HIV prevention and adherence counseling and PrEP medications consistent with the Centers for Disease Control and Prevention (CDC) guidelines.
