Dyadic Developmental Psychotherapy (DDP) was developed by Dr. Daniel Hughes specifically for children who have experienced "developmental trauma"—neglect, abuse, or multiple changes in caregivers (such as in foster care or adoption). These children often struggle with Reactive Attachment Disorder (RAD) or complex trauma, which makes it difficult for them to trust adults or feel safe in a family environment.
The "Dyadic" in the name refers to the relationship between two people—usually the child and the parent. Unlike traditional child therapy where a child plays alone with a therapist, DDP insists that the parent be in the room as an active participant. The goal is to create a "secure base" by repairing the child's internal blueprint of what it means to be cared for.
