This TIP supports learning about the key aspects, functions, and uses of Peer Support Services (PSS) in recovery from problematic substance use, which will help providers, supervisors, and administrators in SUD treatment programs better understand and respond to these changes.

This practical guide updates and expands the discussion presented in SAMHSA's Concept of Trauma and Guidance for a Trauma-Informed Approach Resource from 2014. The primary goal of this guide is to provide implementation strategies across multiple domains based on the original publication.

This guide focuses on research supporting adaptations of evidence-based practices (EBPs) for under-resourced populations. Adaptations involve tailoring care, programs, and services to the cultural, social, gender, and demographic contexts of the people served to yield positive outcomes.
