What researchers measure

Primary outcomes

  1. PrEP uptake

    Filling the PrEP prescription and taking at least one dose of the medication by two weeks following their visit with the PrEP provider

    Time frame: 12 weeks post intervention

Secondary outcomes

  1. Daily PrEP adherence as assessed by the levels of tenofovir (TFV) urine concentrations

    levels of tenofovir (TFV) urine concentrations (\>1000ng/ml) detected in urine shows higher adherence

    Time frame: 90 days post PrEP initiation

  2. Daily PrEP adherence as assessed by the proportion of videos uploaded

    Time frame: 12 weeks post PrEP initiation

  3. Daily PrEP adherence as assessed by the proportion of self reported daily adherence

    Time frame: 12 weeks post PrEP initiation

  4. Enrollment rate as assessed by the number of participants that signed the consent form

    Time frame: 12 weeks post intervention

  5. Number of sessions attended by participants

    Time frame: 12 weeks post enrollment

  6. Study retention as assessed by the number of participants that completed the study

    Time frame: 12 weeks post enrollment

  7. Intervention acceptability as assessed by the Client satisfaction questionnaire

    This is a 15 item questionnaire and each is cored from 1(not at all true)-9( absolutely true), higher number indicating more satisfaction

    Time frame: 12 weeks post intervention
