RCT of an Integrative Intervention for Non-Treatment-Seeking Meth Users (ARTEMIS)

March 7, 2022 updated by: University of California, San Francisco

Randomized Controlled Trial of an Integrative Intervention for Non-Treatment-Seeking Meth Users

In the era of HIV treatment as prevention (TasP), efforts are needed to identify evidence-based combination prevention approaches that achieve greater decreases HIV viral load among populations that are more likely to engage in HIV transmission risk behavior. Because methamphetamine-using men who have sex with men (MSM) are at greater risk for acquiring and transmitting HIV, interventions targeting stimulant use in this population of high-risk men could boost the effectiveness of TasP. At present, only conditional cash transfer approaches such as contingency management (CM) have demonstrated short- term efficacy in reducing stimulant use among substance-using MSM who are not actively seeking formal treatment. The proposed RCT will examine the efficacy of a positive affect intervention that is designed to optimize the effectiveness of CM to achieve long-term reductions in stimulant use and HIV viral load in this population. the team will examine the efficacy of this integrative intervention in a randomized controlled trial (RCT) with 110 HIV-positive, methamphetamine-using MSM. After enrolling in CM, participants will be randomized to receive either: 1) the positive affect intervention; or 2) a attention-matched control condition. Follow-up data will be collected at 3, 6, 12, and 15 months post-randomization. This RCT will provide an opportunity to examine the efficacy of an integrative intervention designed to promote long-term reductions in HIV viral load as the primary outcome. Secondary outcomes that will be examined include: increases positive affect, reductions in stimulant use, improvements in T-helper (CD4+) count, unsuppressed viral load, and decreases HIV transmission risk behavior. Identifying an efficacious intervention approach to decrease HIV viral load among methamphetamine-using MSM would substantially support the goals of the National HIV/AIDS Strategy to reduce HIV incidence and mitigate HIV-related health disparities.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: ARTEMIS+CM
This is a 5-session, individually delivered intervention that is designed to enhance positive affect. It is designed to boost and extend the effectiveness of contingency management (CM).
5-session integrative intervention to improve positive affect as well as boost and extend the effectiveness of contingency management (CM).
12-week CM protocol that provides escalating monetary reinforcement for biological evidence of methamphetamine abstinence. Delivered as the standard of care for non-treatment-seeking methamphetamine-using MSM in San Francisco. Delivered to both the intervention and attention-control arms
Other Names:
  • Positive Reinforcement Opportunity Project (PROP)
Placebo Comparator: Attention-Control+CM
Attention-matched, 5-session control condition consisting of brief-self report psychological measures and neutral writing exercises. Contingency management (CM) is also administered to this arm.
12-week CM protocol that provides escalating monetary reinforcement for biological evidence of methamphetamine abstinence. Delivered as the standard of care for non-treatment-seeking methamphetamine-using MSM in San Francisco. Delivered to both the intervention and attention-control arms
