Personalized HIV and STI Testing Tool (PHASTT)

Randomized, Controlled Trial of the Sex Pro Mobile App for Young Black MSM in San Francisco and Oakland, CA

The PHASTT Study is focused on understanding of facilitators and barriers to mHealth use among young Black men who have sex with men (MSM), and testing a novel mobile app to increase HIV/STI testing and PrEP uptake.

Study Overview

• Status: Unknown
• Conditions: HIV; Risk Reduction; Sexually Transmitted Infections (Not HIV or Hepatitis)
• Intervention / Treatment: Behavioral: Sex Pro mobile Application

Detailed Description

The Sex Pro mobile application (app) being tested facilitates home HIV-testing, home sexually transmitted infection (STI) test self-collection, and pre-exposure prophylaxis (PrEP) uptake. The app integrates a personalized HIV risk assessment with home HIV and STI testing options for young, Black MSM.
