Recruiting

• Conditions: Methamphetamine Abuse
• Interventions: Behavioral: Peer Contingency Management; Behavioral: Standard of Care Contingency Management

• Registration Number: NCT05700994
• Lead Sponsor: Oregon Health and Science University

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).
