This book is the first of its kind to offer a specialist treatment, specifically for ARFID. Developed, refined and studied in response to this urgent clinical need, this book outlines a specialiZed cognitive-behavioral treatment: Cognitive-Behavioral Therapy for Avoidant/Restrictive Food Intake Disorder (CBT-AR). This treatment is designed for patients across all age groups, supported by real-life case examples and tools to allow clinicians to apply this new treatment in their own clinical settings.
