This book introduces a novel, symptom-based approach to CBT for psychosis, inspired by internal medicine's treatment of complex syndromes. This manual advocates for individualized treatment planning based on presenting symptom profiles. Written for clinical psychologists, psychiatrists, and mental health practitioners, this resource offers a structured yet flexible framework that adapts to each patient's needs and supports assessment, case formulation, and intervention selection.

It integrates evidence-based CBT techniques for common symptoms and comorbidities of psychosis, including insomnia, depression, and social anxiety. Practical, step-by-step guidance is provided to support symptom management and functional recovery in complex clinical presentations.

Drawing on years of clinical experience, research, and insights from patients themselves, this manual offers a practical approach to managing psychosis through a transdiagnostic, formulation-driven framework for psychotherapy.
