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.

The Mental Health Awareness Training (MHAT) advisory will promote implementation of MHATs by targeting the workplace more broadly, from traditional settings to places in the community people go all the time.
