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.
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.

Clinical Cut Points for Self-reported Methamphetamine Use Severity
Participants will complete the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST), which provides validated composite scores indexing the severity of methamphetamine use (Mild = 0-3; Moderate = 4-26; Severe = 27 or greater).
Time frame: 6 months
Proportion of Participants Who Reported Receptive Condomless Anal Sex (Receptive CAS)
Participants will complete a detailed behavioral assessment to report the number of men with whom they have had receptive CAS. The proportion of participants reporting any receptive CAS will be reported.
Time frame: 6 months
Proportion of Participants Who Reported Insertive Condomless Anal Sex (Insertive CAS)
Participants will complete a detailed behavioral assessment to report the number of men with whom they have had insertive CAS. The proportion of participants reporting any insertive CAS will be reported.
Time frame: 6 months
