There is increased interest in trauma informed care in the UK and worldwide, however so far there are limited resources for professionals providing training to help health and social care staff (who may have had very little training in attachment theory) to provide care which is trauma informed at an emotional as well as practical level. The CaPLET Training Manual will guide facilitators in making the core psychodynamic concepts - which are relevant to providing trauma-informed care - accessible to health and social care staff. In addition, it will enable facilitators to help staff better understand the people they care for in the context of their histories of trauma and develop insight into the ways in which attending to their own emotional and behavioural responses can help them provide better care.
