Abstract: BACKGROUND: Novel strategies are needed to engage people who use stimulants into the continuum of addiction care. Contingency management (CM) is the most effective intervention for stimulant use disorder and may engage non-treatment-seeking populations, especially when delivered by peer recovery support specialists (peers). We describe development and training for a novel peer-delivered CM program for stimulant use harm reduction and treatment engagement. METHODS: We used a community based participatory research (CBPR) process to develop a CM program focused on self-identified goals for harm reduction and treatment engagement. A steering committee of peers guided study design, CM rewards, schedule, and incentivized goals. Peers completed coaching-to-criterion of six CM skills based on the CM Competence Scale (CMCS), then completed a one-on-one roleplay with a standardized patient. Coaches rated peer performance of each CMCS skill according to its Likert scale (1 = Very Poor to 7 = Excellent) and an a priori rating criterion of 4 ('adequate'). Roleplays included feedback and a 'replay' of skills, if necessary. RESULTS: The steering committee devised two CM interventions: an enhanced standard-of-care incentivizing peer visits ($20 for weekly peer visits) and an intervention that additionally incentivized self-directed goals ($20 for weekly peer visits and $30 for completed goal-related activities). Self-identified goal-related activities were chosen through a collaborative process and organized into 6 domains: (1) overdose/overamping prevention (2) substance use supports/treatment (3) daily living/housing (4) education/employment (5) mental/physical/spiritual health (6) social relationships. Forty-seven peers across nine peer-led organizations (three rural and six urban organizations across Oregon) completed CM training. All 47 peers met the a priori criterion in their roleplay, with seventeen (36%) requiring a 'replay' of a skill. Mean CMSC summary scores were 28.51 (SD 4.73) on the first attempt and 29.62 (SD 4.01) on the second attempt. CONCLUSIONS: PEER-CM (Peers Expanding Engagement in Stimulant Harm Reduction with Contingency Management) is among the first trials to use peer-delivered CM for stimulant use, incentivizing peer engagement and self-identified goals for harm reduction and treatment engagement. A CBPR approach strengthened the study design by incorporating peer guidance. Peers in this large, multisite sample demonstrated adequate CM delivery skills with acceptable fidelity following training.
