Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The overarching goal of this formative research is to examine whether, and in what combination, contingency management (CM) and motivational interviewing (MI) can facilitate entry of stimulant-using men who have sex with men (MSM) into the pre-exposure prophylaxis (PrEP) care continuum.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In Stage 1, participants will be randomized to receive either: 1) three months of CM; or 2) two sessions of MI. All participants will be assessed at three months post-randomization for non-response. In Stage 2, a second randomization where non-responders (i.e., those who have not filled a PrEP prescription) are assigned to: 1) Switch to sequentially receive the other intervention (i.e., CM+MI or MI+CM); or 2) Continue with assessments only (i.e., CM-Only or MI-Only). All participants will complete a final assessment at 6 months.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Contingency Management (CM) - Only (Non-Responder)
