Theory-based Text Messaging to Reduce Methamphetamine Use and HIV Risks Among MSM
In Brief
A clinical study evaluating Text Messages Transmitted by Peer Health Educators (TXT-PHE) and Text Messages Transmitted by Automation (TXT-Auto) for Methamphetamine Abuse and HIV. Completed, enrolled 286 participants across 1 site.
Detailed Summary
Participants receive culturally relevant and specifically tailored text messages based on the behavioral change theoretical constructs of Social Support Theory, Health Belief Model, and Social Cognitive Theory. Participants are randomized into one of three conditions for an 8-week intervention period: Group 1: culturally relevant theory-based text messages interactively transmitted by peer health educators (TXT-PHE); or, Group 2: the same culturally relevant theory-based text messages transmitted by automation (TXT-Auto); or, Group 3: assessment-only (AO) control with no theoretically based text messages.

Timeline
Interventions
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.
