Dyadic Developmental Psychotherapy : An Evidence-Based and Effective Treatment for Trauma and Disorders of Attachment

An Evidence-Based and Effective Treatment for Trauma and Disorders of Attachment Arthur Becker-Weidman, Ph.D. Director, Center For Family Development INTRODUCTION The purpose of this article is to outline several of the elements of Dyadic Developmental Psychotherapy and demonstrate the evidence base for those components. While there have been a two outcome studies using control groups that demonstrated the overall effectiveness of Dyadic Developmental Psychotherapy, the treatment is an integration of several approaches, methods, and techniques that each have strong evidence and empirical bases. The two outcome studies, coupled with the evidence base for the components of Dyadic Developmental Psychotherapy, provide support for the efficacy of this model of treatment. A recent meta-analysis (Craven & Lee, 2006), based on the partial and preliminary results of one study in 2004, determined that Dyadic Developmental Psychotherapy is, “supported and acceptable” (p.301).
