This book presents an innovative approach to intensive treatment for eating disorders in adolescents, rooted entirely in the cognitive-behavioral framework. It offers a comprehensive overview of the treatment program, enriched with numerous clinical examples to illustrate key concepts. The text provides practical guidance on implementing cognitive behaviour therapy in high-intensity care settings, such as intensive outpatient programs and inpatient units, specifically for individuals with severe eating disorders. It also outlines how a multidisciplinary team can cohesively deliver a unified therapeutic intervention. Readers will learn how to apply a structured, manual-based treatment approach within demanding, real-world clinical environments. This resource is ideal for professionals involved in the care of eating disorder patients?including psychologists, psychiatrists, medical doctors, dietitians, and educators?with particular value for those working collaboratively within multidisciplinary teams in intensive care settings. This manual is intended for clinicians involved in the care of adolescents with eating disorders, including psychologists, psychiatrists, internists, endocrinologists, dietitians, nutritionists, nurses, educators, and physical therapists. This book will also benefit professionals outside of specialist eating disorder services?such as gynaecologists, gastroenterologists, general practitioners, and psychotherapists?who frequently encounter patients with eating disorder comorbidities.
