Methamphetamine Abuse
Conditions
Brief summary
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.
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).
Interventions
BEHAVIORALPeer Contingency Management
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)
BEHAVIORALStandard of Care Contingency Management
Participants allocated to standard of care contingency management will receive incentives for peer encounters.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants who overdose | 6 months from baseline | 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. |
| Number of participants who achieve self-identified goals | 6 months from baseline | 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. |
| Number of participants who engage in substance use disorder treatment | 6 months from baseline | 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. |
