This book is about Trauma-Informed Care (TIC) for people who have intellectual disabilities (ID). The provision of health and social care services is becoming more trauma informed, including in services for people with ID, where the experience of trauma is being increasingly acknowledged. This book addresses a gap in resources to guide those supporting people with ID by showing how services can work in a trauma informed way. Including contributions from authoritative professionals in the field, and a powerful account of abuse from an expert by experience, the book provides an overview of the history which underpins the importance of trauma and TIC, and the impact of trauma on people who have ID. The second part of the book looks at trauma informed services and a growing and diverse range of therapeutic interventions, including positive behavioural support, intensive interaction, cognitive behavioural psychotherapy, dyadic interpersonal psychotherapy, developmental and psychodynamic approaches.
