DDP stands for both "Dynamic Deconstructive Psychotherapy" developed by Onno van der Hart and Ellert Nijenhuis, and "Dyadic Developmental Psychotherapy" developed by Dan Hughes.
Both therapies are used in the treatment of complex trauma, including dissociative disorders such as DID.
Dynamic Deconstructive Psychotherapy
Dynamic Deconstructive Psychotherapy is an integrative therapy that focuses on helping patients understand and change maladaptive patterns of behavior, emotion and cognition caused by severe and prolonged trauma.
It's also been called "Dynamic De-coupling Process."
This approach to treating Dissociative Identity Disorder (DID) is a form of psychodynamic therapy that aims to help the patient understand and integrate their dissociated parts, also known as "alters" or "identities", with the goal of achieving a more cohesive sense of self. DDP was developed by Dr. Onno van der Hart and Dr. Ellert Nijenhuis in the late 1990s and early 2000s. DDP is based on the idea that DID is caused by complex developmental trauma, and that this trauma is often related to a history of severe, prolonged abuse and neglect in childhood. The therapy is focused on addressing the trauma and its effects on the patient's mind, emotions and behavior. It also involves building a therapeutic alliance with all the patient's dissociated identities and working with them in a collaborative and respectful way. Some of the techniques used in DDP include imagery rescripting, inner dialogue, and emotional processing. The therapy is typically long-term and can take several years to complete.
Dyadic Developmental Psychotherapy
Dyadic Developmental Psychotherapy is a relationship-based therapy that focuses on the patient's attachment relationships, and how these relationships have been affected by trauma and dissociation. Both therapies are considered to be evidence-based treatments for DID and other dissociative disorders.
It is a therapeutic approach that focuses on the relationship between the therapist and the patient, and aims to help the patient develop a sense of safety, trust and emotional regulation. It was originally developed to work with children and their caregivers, but has been adapted for use with adults with complex developmental trauma, including those with DID. Dyadic therapy emphasizes the importance of creating a secure attachment relationship between the therapist and the patient, which is thought to be crucial for healing from trauma. The therapist works to help the patient understand the connection between past experiences and current symptoms and behaviors, and to develop new ways of coping with difficult emotions and memories.
