Evolution of the assertive community engagement model for peer recovery coaching informed by the assertive community treatment model

Peer recovery support services for Substance Use Disorder (SUD) are becoming increasingly more prevalent to support individuals in initiating and maintaining recovery. However, models that operationalize service delivery are lacking. Here we describe the Assertive Community Engagement (ACE) model, a new model that emphasizes personalization and peer recovery support with a social determinants of health focus. This article defines the tenets of the ACE model, provides evidence to support the model, and addresses applications of this model to different settings. We review literature on Assertive Community Treatment (ACT) programs and research using peer recovery coaching interventions to develop the ACE model tenets, implementation guidelines, and evidence in support of the model. The ACE model has ten core tenets for service delivery: (1) the target population is individuals with SUD; (2) peer recovery coach services as a single touchpoint; (3) service delivery relies on assertive engagement techniques; (4) comprehensive support services are provided; (5) services include long-term care; (6) community-based care is provided; (7) services have 24/7 crisis availability; (8) outcomes focus on both substance use reduction and quality of life improvements; (9) direct social support is provided; (10) services are personalized and flexible. Empirical evidence for the model includes evidence for increase engagement in treatment and other recovery support services, reduced substance use frequency, and decreased hospital utilization. The ACE model is a promising model of peer recovery support that deserves further investigation for improving substance use and quality of life outcomes.
