Rachman, Emeritus Professor, Institute of Psychiatry, London University, and University of British Columbia."Specialized Cognitive Behavior Therapy for Obsessive Compulsive Disorder: An Expert Clinician Guidebook by Dr. Debbie Sookman is an outstanding contribution to the science and clinical practice related to the full range of Obsessive Compulsive Disorder. This is an excellent book in every way imaginable. Clearly written and organized, Sookman provides a critical and scholarly review of the state of the art on OCD.Every researcher and clinician can benefit from this superb book. The reader benefits from the considerable clinical experience and scholarship that Dr Sookman possesses, while learning specific and powerful tools in helping those who suffer from OCD. Case examples illustrate the importance of conceptualization and the value of empirically supported treatments. I am particularly impressed that Sookman was able to balance such sophistication in her critical and scientific understanding of OCD, while still writing a clear and concise book on the topic. This is a book I will recommend to both beginning clinicians in training and to seasoned researchers and practitioners."--Robert L. Leahy, Ph.D., Director, American Institute for Cognitive Therapy"Dr. Sookman's book is a remarkable compilation of the current literature on Obsessive-Compulsive Disorder (OCD). Dr. Sookman emphasizes the need for evidence based treatments and elaborates what these are, how specialty cognitive behavior therapy interventions are best applied, their efficacy rates and the reasons for failure. Case illustrations make this guidebook especially compelling. I strongly recommend this expert guidebook to everyone who is interested in OCD."--Fugen Neziroglu, Ph.D., ABBP, ABPP, Director of the Bio-Behavioral Institute, Great Neck, NY and author of numerous books including, Overcoming Body Dysmorphic Disorder and Overcoming Compulsive Hoarding, both OCD Spectrum Disorders.
