Dyadic Developmental Psychotherapy: an evidence-based treatment for children with complex trauma and disorders of attachment

Dyadic Developmental Psychotherapy (DDP) is a family therapy treatment based on Attachment Theory. It is an integration of several approaches, methods and techniques that have a strong evidence base. The approach was originally developed to treat children with disorders of attachment and has been shown to be effective. It has since been more broadly used to help families with a variety of difficulties, including complex trauma. This paper outlines the primary principles and components of DDP and the evidence to support the effectiveness of the components and, therefore, of DDP.
