About DDP

DDP stands for Dyadic Developmental Psychotherapy

Dyadic Developmental Psychotherapy

Dan from his website IMG_9080Dan Hughes, a Clinical Psychologist,  created Dyadic Developmental Psychotherapy (DDP) as a treatment for families with adopted or fostered children who had experienced neglect and abuse in their birth families and suffered from significant developmental trauma.

DDP is based on and brings together attachment theory, what we understand about developmental trauma, the neurobiology of trauma, attachment and caregiving, intersubjectivity theory and child development.

They may believe that parents aren’t safe and can’t always be turned to for comfort and help. They may develop insecure attachments and try to stop their new parents from becoming emotionally close to them.

The therapy helps the children learn to trust.  It is family-based and involves the child with his or her caregivers.

Dyadic Developmental Parenting

He found that ordinary parenting often failed to help the children and so developed his therapeutic model to encompass a new way of day to day parenting based on the principles of PACE.

Dyadic Developmental Practice

All professionals supporting children and families need a model that brings together knowledge about developmental trauma, attachment, interpersonal neurobiology and child development.

Dyadic Developmental Practice is an all encompassing approach that includes parenting and caring for children as well as the therapy. It helps the professionals understand, work together with and be effective in their support of children and their families.


Playfulness, Acceptance, Curiosity and Empathy

Central within DDP is PACE, a way of thinking which deepens the emotional connections in our relationship with others.

Playfulness brings enjoyment to the relationship. Acceptance creates psychological safety.  When we curiously explore within a relationship we express a desire to know the other more deeply. Empathy communicates our curiosity and acceptance, as we recognize and respond to the other’s emotional experience.
