Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Control
No intervention. Pre-post evaluations will be administered.
Experimental: Face-to-face intervention
A three-session face-to-face intervention using Motivational Interviewing with a facilitator; to increase Pre-Exposure Prophylaxis (PrEP) uptake. Pre-post-post evaluations after each session will be administered. Participation will last 150 days from the start to the last follow-up.
Behavioral: Motivational Interviewing
Upon refinement from Formative Research (Aim 1), a three-session, individual-level intervention to increase Pre-Exposure Prophylaxis (PrEP) uptake among men who have sex with men (MSM) in Puerto Rico will be implemented. The facilitator will use Motivational Interviewing techniques to guide the sessions. The intervention's design and content will be the same for each study group; the only difference will be the modality of implementation; one group of participants will receive a face-to-face intervention, while another group will receive an online intervention.A total of 170 participants will be randomized in a 1:1 ratio into each of the two intervention modalities (n=85 face-to-face and n=85 online) while a control group will be recruited following a 3:1 ratio of intervention vs. control. In addition to baseline assessment, participants will be asked to complete a post test at the end of the third session (60 days) and a follow-up post-test at the 150-day mark, separately.
Experimental: Online intervention
A three-session online intervention using Motivational Interviewing with a facilitator; to increase Pre-Exposure Prophylaxis (PrEP) uptake. Pre-post-post evaluations after each session will be administered. Participation will last 150 days from the start to the last follow-up.
