DDP is a model of treatment and parenting for children with problems secondary to abuse, neglect, and multiple placements. When a child's early attachment history consists of abuse, neglect, and/or multiple placements, they have failed to experience the dyadic (reciprocal) interaction between a child and parent that is necessary for normal development and they often have a reduced readiness and ability to participate in such experiences. Many children, when placed in a foster or adoptive home that provides appropriate parenting, are able to learn, day-by-day, how to engage in and benefit from the dyadic experiences provided by the new parent. Other children, who have been much more traumatized and compromised in those aspects of their development that require these dyadic experiences, have much greater difficulty responding to their new parents. For these children, specialized parenting and treatment is often required.
Within this model, the foundation of these interventions--both in home and in treatment--must incorporate attitude based on playfulness, acceptance, curiosity, and empathy. It must never involve coercion, threat, intimidation, and the use of power to force submission.
Note: There has been controversy regarding Dyadic Developmental Psychotherapy as an appropriate treatment. Based on the available literature, there is no evidence of harm from the use of DDP as described by the developers.
