Dialectical behavior therapy (DBT) is a specific type of cognitive-behavioral psychotherapy developed in the late 1980s by psychologist Marsha M.Linehan to help better treat borderline personality disorder.Since its development, it has also been used for the treatment of other kinds of mental health disorders. The Oxford Handbook of DBT charts the development of DBT from its early inception to the current cutting edge state of knowledge about both the theoretical underpinnings of the treatment and its clinical application across a range of disorders and adaptations to new clinical groups. Experts in the treatment address the current state of the evidence with respect to the efficacy of the treatment, its effectiveness in routine clinical practice and central issues in the clinical and programmatic implementation of the treatment. In sum this volume provides a desk reference for clinicians and academics keen to understand the origins and current state of the science, and the art, of DBT.
