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).
