This comprehensive and accessible guide provides a practical introduction to Cognitive Behavioural Therapy (CBT) and a clear overview of the full range of cognitive and behavioural interventions used across health settings. Covering all major schools of CBT, including third wave interventions, it explains key techniques through real-world case examples and makes complex concepts easy to understand and apply. Designed for early-careers psychiatrists, medical students, and other mental health practitioners, this book fills an important gap between specialist CBT and everyday clinical practice. Recognising that most patients presenting with mental health problems have multiple diagnoses, the authors explore CBT applications across a wide range of conditions. Uniquely, this book also considers how medication can be used alongside CBT to optimise outcomes. Written by CBT pioneer Professor Lynne Drummond, this is an indispensable text for all mental health professionals.
