The purpose of the “Trauma Informed Care Approaches for Working with Individuals with Substance Use Disorders” training is to introduce participants to the presentation of trauma among clients and the relation between traumatic experience and the development of substance use disorders. Key topics include: an overview of trauma presentations across the lifespan; socioecological conceptualizations of early childhood trauma leading to later life judicial and medical impairments; and skills and strategies to intervene with clients who have co-occurring trauma and substance use disorders.
