"This is an outstanding book. Clark has undertaken the considerable task of reviewing all of the key literature on OCD, from early behavioral research to current cognitive theories and tactics. Coverage of definitions, diagnostic criteria, epidemiology, and assessment is balanced and up to date. Naturally, the book is particularly strong on the subject of obsessions, as Clark has made a significant research contribution here and is an accepted authority. Well organized and comprehensive, the book is bolstered by many tables and summaries. It may well become a standard reference and is likely to be required reading in clinical graduate programs."--S. Rachman, PhD, University of British Columbia"This book fills an important gap in the treatment literature. The coverage is detailed and thorough, providing a good balance of theory, research, and step-by-step clinical suggestions. Clark's expertise and experience, both as a scientist and a clinician, are evident in this extremely well-written work. Students learning to apply evidence-based strategies to the treatment of OCD will find this to be an invaluable resource."--Martin M. Antony, PhD, Ryerson University, Toronto"This very readable and wonderfully detailed volume provides up-to-date and comprehensive coverage of the phenomenology of OCD, as well as the theoretical and research basis for understanding this complicated condition. Initial chapters provide a wealth of information on diagnostic distinctions and set the stage for knowledgeably applying the treatment techniques contained in the second half of the book. These strategies are clearly presented with numerous examples and helpful tables, handouts, and therapy forms. Especially useful is the detailed presentation of the subtleties of effective cognitive and behavioral interventions. Overall, this is a truly excellent handbook that should be on the shelves of practicing clinicians, academic instructors, and advanced graduate students interested in the psychopathology and treatment of OCD."--Gail Steketee, PhD, Boston University School of Social Work"This volume is exciting reading for anyone interested in recent developments in cognitive-behavioral theories and therapies of obsessive-compulsive disorders. David A. Clark has written a cohesive, comprehensive book that is scholarly yet at the same time contains much of value for the clinician. Provided is a much-needed, theoretically and empirically guided CBT treatment manual for obsessional disorders. Highly recommended!"--Paul M.G. Emmelkamp, PhD, University of Amsterdam
