Mobile Messaging Intervention to Present New HIV Prevention Options for Men Who Have Sex With Men (MSM)

This study aims to evaluate the use and effectiveness of a smartphone‐based messaging platform as a public health strategy for improving participants' self‐reported sexual health and prevention behaviors, beliefs and attitudes. The study will enroll 1,206 men into a randomized controlled trial. They will be assigned to either the immediate intervention group ("intervention arm") or the waitlist‐control group ("waitlist‐control arm"). All participants will take an assessment survey at baseline, and the intervention group will be oriented on the installation and use of the messaging app upon randomization to that group. All men in the randomized controlled trial will complete short follow‐up surveys at 3‐month intervals during the 9‐month follow‐up period. When the intervention arm activities and assessments have concluded, participants in the waitlist‐control arm will then be given the option of accessing to the intervention app and participation in intervention post‐test activities.
