About this study

Official title: Mhealth for Pre-exposure Prophylaxis Adherence by Young Adult MSM

This Phase 2 project aims to enhance and test a mobile health intervention designed to increase adherence to the daily PrEP pill among culturally-diverse young adult men who have sex with men. The intervention will include: a) personalized PrEP pill reminders b) culturally- and developmentally-sensitive text messages targeting patient education, motivation, and stress c) a gamification avatar and d) a linked online community of peers. Effectively promoting PrEP adherence would reduce new HIV infections in this at-risk population, which is subject to health disparities

Read the detailed description

The project is to develop and test the effectiveness of an individually-tailored, developmentally- and culturally-sensitive, mobile health (mhealth) PrEP adherence intervention called DOT. The intervention will target culturally-diverse, young adult men, ages 18-35, who have sex with men (YMSM). The recent rise in HIV infection among young people, particularly minority YMSM, points to the value of PrEP uptake and adherence support for YMSM. In PrEP efficacy trials, younger age was the most consistent correlate with low PrEP adherence. Our DOT mhealth intervention reflects a developmental understanding of young adult decision-making, and is uniquely combined with principles from social cognitive theory, positive psychology and behavioral economics. The proposed project is based on Dr. Weitzman's successful Phase 1 trial of DOT, which led to significant improvements in PrEP adherence, PrEP treatment self-efficacy, and intention to follow PrEP treatment guidelines among the YMSM that used DOT for six weeks. Our proposed Phase 2 DOT mhealth intervention is directly responsive to Phase 1 findings by adding: 1) texts targeting motivation, patient education, and stress burden 2) online community for social support 3) linkage to the federal crisis text line 4) virtual avatar 5) cloud-based platform to view user engagement 7) calendar for clinic appointments and pharmacy refills 8) enhanced personalization of pill reminders and 9) enhanced adherence graphing. In Phase 2, we will test the effectiveness of DOT at improving PrEP adherence in a randomized controlled trial.

ControlNo interventionParticipants in the control group will receive a 2-page PrEP patient education document based information about PrEP from on the CDC website.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Wilson Self-reported Medication Adherence Scale

    The self-reported medication adherence scale, developed by Wilson et al. (2016), is designed to assess self-reported medication adherence to HIV-related and other types of medications. In this study, it was used to assess self-reported PrEP medication adherence. Minimum score=0, maximum=299.9. Higher score means better adherence.

    Measured: 90 days

Secondary outcomes (4)
  1. PrEP Medication Adherence Self Efficacy Scale

    This scale was adapted by Kogelman and Weitzman from the Johnson HIV Adherence Self-Efficacy Scale. The PrEP medication adherence self efficacy scale was developed to assess one's confidence in one's ability to adhere to their PrEP medication treatment plan. The minimum score = 0, maximum score =80. Higher score indicates greater PrEP medication adherence self efficacy.

    Measured: 90 days

  2. Intention to Follow PrEP Treatment Guidelines

    This measure was developed by Kogelman and Weitzman to assess an individual's intention to engage in key behaviors that are recommended while on PrEP treatment, e.g. concomitant use of condoms and testing for HIV every 3 months. The minimum score=0, the maximum score=16. Higher score means greater intention to follow PrEP treatment guidelines.

    Measured: 90 days

  3. PrEP Medication Knowledge Measure

    This measure was developed by Kogelman and Weitzman to assess an individual's knowledge of PrEP medication through questions about medication purpose, side effects, etc. Minimum score =0, maximum score = 8. Higher score means greater knowledge about PrEP medication.

    Measured: 90 days

  4. Perceived Stress Scale

    The Perceived Stress Scale, developed by Cohen et al. (1983), is designed to measure the degree to which one perceives situations in one's life as stressful. The minimum score=0, maximum score=40. Higher score indicates higher perceived stress.

    Measured: 90 days

Questions about this trial

What is this clinical trial studying?

A study testing DOT mobile app in people with Hiv, run by Environment and Health Group, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Wilson Self-reported Medication Adherence Scale (time frame: 90 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Dec 2023.
