About this study

The main goal of this study is to tests the effect of incentivizing achievement of self-identified, personal harm reduction goals (Contingency management or CM) compared with standard of care (peer harm reduction service with incentives for peer visits) to increase the reach and effectiveness of methamphetamine (MA) harm reduction services.

Read the detailed description

Using a hybrid type 1 effectiveness-implementation framework and stepped-wedge design, this study will randomize eighteen community-based peer harm reduction sites to provide contingency management incentives for achieving self-identified harm reduction goals set with peer specialists using a participant-driven harm reduction goal-setting process (e.g. completing overdose prevention and supply training, daily life goals, treatment and care goals, relationship and social support goals) versus standard of care contingency management (i.e. incentives for peer encounter attendance).

Being tested
Peer Contingency Management, Standard of Care Contingency Management

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Peer Contingency ManagementBehavioural

    Also called PEER-CM

    Participants allocated to peer-facilitated contingency management will receive incentives for achieving self-identified harm reduction goals set with peer specialists using a participant-driven harm reduction goal-setting process (e.g. completing overdose prevention and supply training, daily life goals, treatment and care goals, relationship and social support goals)

  • Standard of Care Contingency ManagementBehavioural

    Also called Standard of Care

    Participants allocated to standard of care contingency management will receive incentives for peer encounters.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of participants who overdose

    Test the impact of incentives for achieving self-identified, personal harm reduction goals on the likelihood of overdose among people using methamphetamine at 6 months from enrollment identified through completed assessment.

    Measured: 6 months from baseline

  2. Number of participants who achieve self-identified goals

    Determine whether incentives for achieving self-identified, personal harm reduction goals increases engagement with harm reduction services at 6 months from enrollment identified through completed assessment.

    Measured: 6 months from baseline

  3. Number of participants who engage in substance use disorder treatment

    Determine whether incentives for achieving self-identified, personal harm reduction goals increases engagement with treatment services at 6 months from enrollment identified through completed assessment.

    Measured: 6 months from baseline

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants who overdose (time frame: 6 months from baseline). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05700994, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jan 2026; AzTrials last refreshed its copy on 30 Oct 2026.
