Interventions

  • BehavioralAttention-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.

  • BehavioralMY-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.

What researchers measure

Primary outcomes

  1. Change in substance use

    Time frame: baseline, end of intervention (3 months after baseline), 3 months after intervention, 6 months after intervention, and 12 months after intervention

Secondary outcomes

  1. Change in condom use

    Time frame: baseline, end of intervention (3 months after baseline), 3 months after intervention, 6 months after intervention, and 12 months after intervention

  2. Change in PrEP uptake as assessed by the self reported tool

    PrEP uptake is defined as the self initiation of HIV prevention medication

    Time frame: baseline, end of intervention (3 months after baseline), 3 months after intervention, 6 months after intervention, and 12 months after intervention

  3. Change in sexually transmitted infections (STIs)

    This will be assessed by a blood test to detect biomarkers for HIV and Syphilis, and urine test for Gonorrhea and Chlamydia

    Time frame: baseline, end of intervention (3 months after baseline), 3 months after intervention, 6 months after intervention, and 12 months after intervention
