There is national and international recognition of the importance of working in a trauma informed way when interacting with others, and public statements to that effect by services and organisations in Wales. The ACE Support Hub are working with Traumatic Stress Wales to develop a “National Skills and Knowledge Framework to Respond to Trauma”. As part of this framework, and in line with the recommendation from Welsh Government, the ACE Support Hub have identified a need to better understand the use of trauma informed terminology, the definitions being attributed to the terminology and the approaches being implemented across programmes, projects and interventions (PPIs) in Wales.
