Study Description

Brief 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.

Condition or disease	Intervention/treatment	Phase
Methamphetamine Abuse; HIV	Behavioral: Text Messages Transmitted by Peer Health Educators (TXT-PHE); Behavioral: Text Messages Transmitted by Automation (TXT-Auto)	Not Applicable

Detailed Description:

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. Participants in all three conditions receive brief weekly text-message assessments on their methamphetamine use and HIV sexual behaviors in the previous seven days. 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).

Arms and Interventions

Arm	Intervention/treatment
Experimental: TXT-PHE; Gay-specific, Theory-based Text Messages Transmitted by Peer Health Educators (TXT-PHE) 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"). 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.	Behavioral: 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.
Experimental: TXT-Auto; Group 2: Gay-specific, Theory-based Text Messages Transmitted by Automation (TXT-Auto) 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.	Behavioral: Text Messages Transmitted by Automation (TXT-Auto); 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.
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.

Outcome Measures

Primary Outcome Measures :

1. Methamphetamine Use [ Time Frame: 9-months post randomization ]
   Self-reported and/or biomarker-confirmed methamphetamine use assessed at baseline and 9-month follow-up assessment.
2. HIV Sexual Risk Behavior [ Time Frame: 9-months post randomization ]
   Engagement in condomless anal intercourse was assessed at baseline and 9-month post-randomization follow-up.
3. Cost Effectiveness [ Time Frame: up to 36 months ]
   Cost-effectiveness data is collected quarterly throughout the course of the study using the UNAIDS template.

Secondary Outcome Measures :

1. HIV Primary Care [ Time Frame: 8-weeks post randomization, 3-/6-/9-months post randomization ]
   HIV-positive participants will be assessed according to their linkage/retention in HIV primary care and adherence to ART medication at 8-weeks, 3-, 6-, and 9-months post-randomization.
