Dyadic Developmental Practice has evolved from a model of direct therapy (DDP) originally developed for children who are fostered or adopted. This therapeutic approach is tailored to building relationships and to help address past trauma experiences.

This book will be the first to offer DDP approaches and adaptations when supporting children and adults with an intellectual disability (ID).The authors outline the key concepts and frameworks used in DDP, illustrated through a range of case studies and practice examples. The book considers all elements of DDP including psychotherapy, parenting practices and PACE, as well as offering ways to draw on the DDP framework to enhance PBS-focused work within services. Including key resources developed for future training and supervision, Dyadic Developmental Practice and Intellectual Disability is written in an accessible style for health workers and social care staff.
