Theory-based Text Messaging to Reduce Methamphetamine Use and HIV Risks Among MSM

"Participants receive five gay-specific, theory-based pre-written messages per day sent on a predetermined schedule. Participants who respond to the pre-written text messages or initiate queries or requests for support (pull) are sent additional real-time messages back from the PHE. Text messages are transmitted and responded to in real time, at the peak hours of high-risk activities. During the 8-week intervention, participants receive a brief weekly text-based assessment on their methamphetamine use and HIV sexual behaviors in the previous seven days."
