Evaluation of 3T, a Sex-Positive HIV/STI Mobile App Intervention for Young Black Men Ages 14-19 Attracted to Men

This study features a 2-arm cluster randomized controlled trial with approximately 300 young black men who have sex with men (YBMSM) to assess the effectiveness of the 3T mobile app. To be eligible participants will be required to identify as male; Black, African-American, or biracial Black/African American; age 14-17 at baseline; self-identify as gay, bisexual, fluid, or sexually attracted to men; own a smartphone, and reside in any state in the United States. Those in the treatment arm will be provided with the 3T app, to be downloaded to their own device, and asked to use it during a three month period. Those in the control arm will be asked to download a general health app and use it during the same three month period. Participants will complete brief online surveys at baseline and at 3- and 6-months following the conclusion of the app-use period to assess effectiveness in changing sexual risk behaviors and communication and condom use behaviors and attitudes.
