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 presents five evidence-based programs and practices that address the prevention and treatment of common mental health concerns: gatekeeper trainings, mindfulness-based stress reduction, acceptance and commitment therapy, cognitive behavioral therapy, and dialectical behavior therapy.
