Anorexia Nervosa has one of the highest death rates of all mental illnesses and one of the poorest treatment outcomes. However, one novel treatment, the neurobiologically-based treatment Temperament-Based Therapy with Supports (TBT-S), works with clients’ temperament and traits to motivate change, ultimately managing and reducing symptoms. This practical and accessible book is the first guide to delivering TBT-S that addresses the underlying traits leading to symptoms of anorexia nervosa and helps people to manage symptoms long-term. It offers background information on the role of temperament in anorexia nervosa, the development of the TBT-S protocol and the evidence gathered. Chapters also covers how to augment this therapy into existing treatment. A valuable resource for clinicians involved in the treatment of anorexia nervosa, including psychologists, psychiatrists, psychotherapists, specialist nurses, dieticians, and educators.
