Dyadic Developmental Psychotherapy (DDP) is a therapeutic approach developed to meet the specific developmental needs of children and young people who have experienced significant adversity and interpersonal trauma, often in the context of their primary attachment relationships. It focuses primarily on the central importance of healthy and supportive relationships to aid trauma recovery.

It is most often used with children who have been adopted, fostered, or living in residential or kinship care. It can also help children who live with their birth parents so long as the current home and parenting provided is safe and nurturing.

DDP aims to enable children to experience safety, security and increased trust in their relationships with their parents, and to develop deeper emotional connection (and emotional processing) in the child-parent relationship.
