PrEP Readiness Interventions for Sustained Motivation (PRISM)

This is a hybrid type I randomized controlled trial to test the effectiveness of contingency management (CM) alone versus CM with motivational interviewing (MI) for optimizing entry or re-entry into the HIV prevention or care continua. A total of 400 participants will be randomized to CM (n = 200) or MI+CM (n = 200), all delivered via telehealth. Monthly follow-up assessments will be completed over 12 months to examine effectiveness MI+CM for the primary outcome - filling a pre-exposure prophylaxis (PrEP) or anti-retroviral therapy (ART) prescription (verified using a digital photo). Secondary outcomes will include: self-reported PrEP or ART clinical evaluation by a provider; self-reported meth and other substance use severity (ASSIST), and self-reported receptive and insertive condomless anal sex (CAS).
