  • Methamphetamine Use [ Time Frame: up to 9-months post randomization ] [ Designated as safety issue: No ]
    Self-reported and/or biomarker-confirmed methamphetamine use is assessed at baseline, weekly throughout the 8-week intervention, and at 3-, 6-, and 9-month follow-up assessments.
  • HIV Sexual Risk Behavior [ Time Frame: up to 9-months post randomization ] [ Designated as safety issue: No ]
    Self-reported HIV sexual risk behaviors and/or biomarkers for HIV and STIs are assessed at baseline, weekly throughout the 8-week intervention, and at 3-, 6-, and 9-month post-randomization follow-up.
  • Cost Effectiveness [ Time Frame: up to 36 months ] [ Designated as safety issue: No ]
    Cost-effectiveness data is collected quarterly throughout the course of the study using the UNAIDS template.

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

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. Participants in all three conditions receive brief weekly text-message assessments on their methamphetamine use and HIV sexual behaviors in the previous seven days. Data related to intervention costs as well as relative exposure to each theoretical construct will be examined to determine cost- and mechanism-effectiveness, respectively. The randomized three-group design uses repeated assessments at baseline, at the end of the 8-week intervention period, and at 3-, 6-, and 9-month post randomization follow-up. This study will determine the differential immediate and sustained effects of transmitting theory-based text messages by PHE (TXT-PHE) versus by automation (TXT-Auto), compared to an assessment-only (AO) control condition among out-of-treatment, methamphetamine-using MSM for reductions of methamphetamine use and HIV sexual risk behaviors. It is hypothesized that there will be significantly greater reductions in methamphetamine use and HIV sexual risk behaviors from text messages transmitted by PHE than by text messages transmitted by automation, which in turn will produce significantly greater reductions than the AO condition (PHE > TXT > AO). In addition, this study will determine the cost-effectiveness of TXT-PHE vs. TXT-Auto compared to AO for reducing methamphetamine use and HIV sexual risk behaviors. The investigators hypothesize that the TXT-PHE intervention will prove more cost-effective than TXT-Auto in reducing methamphetamine use and HIV sexual risk behaviors, while the TXT-Auto condition will prove more cost effective than the AO condition in reducing these same outcomes (PHE > TXT > AO).

  • Methamphetamine Abuse
  • HIV
  • Behavioral: Gay-specific, Theory-based Text Messages Transmitted by Peer Health Educators (TXT-PHE)
    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.

    Participants receive five gay-specific, theory-based pre-written messages per day sent on a predetermined schedule. 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.
  • Experimental: TXT-PHE

    Group 1: Gay-specific, Theory-based Text Messages Transmitted by Peer Health Educators (TXT-PHE) with "Push and Pull" Interactions.

    Participants assigned to this group receive text-messaging from PHEs. This condition is interactive and tailored to the needs of the individual participant. PHEs initiate (i.e., "push") text messages to participants and also respond to participant-initiated queries and participant responses to the PHE messages (i.e., "pull").

    Following the initial welcome message, participants receive five 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.

    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.

  • Experimental: TXT-Auto

    Group 2: Gay-specific, Theory-based Text Messages Transmitted by Automation (TXT-Auto) with "Push Only" interactions

    Participants assigned to this group receive automatic text-messages.

    Following the initial welcome message, participants receive five pre-written messages per day sent on a predetermined schedule.

    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.

  • No Intervention: Assessment Only (AO)
    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.
