Individual practitioners, programs, and/or systems whose approach to engaging people with a history of trauma involves recognition of the presence of trauma symptoms and acknowledgement of the role that trauma has played in their lives. The approach can be implemented in any type of service setting or organization and has been used in the delivery of a broad range of services including mental health, substance use, housing, vocational or employment support, domestic violence and victim assistance, and peer support. However, it is distinct from trauma-specific interventions or treatments that are designed specifically to address the consequences of trauma and to facilitate healing.
