Assessing the Use of MY-RIDE, a Just-in-time Adaptive Intervention, to Improve HIV Prevention and Substance Use in Youth Experiencing Homelessness

May 8, 2026 updated by: Diane Santa Maria, The University of Texas Health Science Center, Houston
The purpose of this study is to determine whether Motivating Youth to Reduce Infections, Disconnections, and Emotion dysregulation (MY-RIDE) decreases substance use , to determine whether MY-RIDE increases human immunodeficiency virus (HIV) prevention strategies and to evaluate MY-RIDE effects on willingness to take Pre-Exposure Prophylaxis (PrEP), stress, substance use urge, and use of mental health and substance use services when compared to attention control youth

Design Details

  • Primary Purpose: Prevention
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: MY-RIDE group
Behavioral: MY-RIDE group
MY-RIDE has three main components: 1) One nurse-led face-to-face session; 2) three months of Ecological Momentary Assessments (EMA) with personalized messaging delivered by phone in real-time in response to one's current risk; and 3) access to on-demand healthcare/PrEP navigation and referrals.
Active Comparator: Attention-control group
Behavioral: Attention-control group
Participants will receive a one-hour general health promotion session from a nurse and be issued a phone that will deploy the EMA on the same schedule as the intervention arm. They will also receive usual care from the clinics, drop-in center, and shelter recruitment sites. Usual care includes accessing social workers and case managers for immediate housing, food, and clothing needs and assistance in navigating the local Continuum of Care system to access social services.
