Brief Summary

This study aims to: 1) adapt the theory-based P3 (Prepared, Protected, emPowered) app designed to improve pre-exposure prophylaxis (PrEP) adherence, retention in PrEP clinical care, and PrEP persistence among young gay, bisexual, and other men who have sex with men (YMSM) in the United States for YMSM in Thailand, and 2) conduct a pilot randomized controlled trial (RCT) to assess the feasibility, acceptability, and potential impact of the adapted P3-Thailand (P3-T) app.

Outcome Measures

Primary Outcomes (3)

  • Intervention Feasibility: Average Number of Days of Any App Use

    The number of days of any app use among those assigned to the P3-T adherence arm during the 3-month intervention period as recorded by backend app metrics. Higher number of days indicates higher intervention feasibility.

    Month 3

  • Intervention Feasibility: Average Number of Days of PrEP Medication Tracked Through App

    The number of days of PrEP medication tracked through app during the 3-month intervention period among participants assigned to the P3-T adherence arm as recorded by backend app metrics. Higher number indicates higher intervention feasibility.

    Month 3

  • Intervention Acceptability: Mean Intervention Acceptability, Composite Score CSQ-8

    Intervention acceptability was assessed using the Client Satisfaction Questionnaire (CSQ-8), an 8-item validated scale measuring the construct of global intervention satisfaction, collected in the 3-month follow-up survey (intervention group only). The eight items (quality of app, kind of service received from app, app met needs, recommend app to a friend, amount of help received from app, the effectiveness of app for dealing with health issue (PrEP adherence), overall satisfaction, and willingness to use the app again) were assessed using a 4-point response scale with individually specified anchors. The mean composite score of the CSQ-8 was calculated with a total possible range of 8 (lowest acceptability, worst outcome) to 32 (highest acceptability, best outcome).
