Providing an introduction to the fascinating world of those with problematic obsessions and compulsions, this is the fully revised and updated second edition of Obsessive-Compulsive Disorder: Etiology, Phenomenology, and Treatment. Many of the world's leading researchers and clinicians contribute chapters to this volume, which covers everything from the causes of OCD, to how it manifests across different cultural settings, to evidence-based treatments. Both new clinicians and those experienced with the disorder will find useful information inside, as will those seeking to learn more for themselves or their family members.


Caleb W. Lack, Ph.D. is a clinical psychologist and Professor of Psychology at the University of Central Oklahoma. A best-selling author and award-winning educator, he specializes in anxiety, obsessive-compulsive, and trauma disorders, as well as training others in the evidence-based treatment of mental health problems.


"This essential guide for OCD, a highly complex and heterogeneous disorder, is indispensable for clinicians who aim to deliver evidence-based care. It is the rare text that covers fundamental symptoms along with sensitive complexities such as religion, culture, race, and family dynamics in a straightforward and user-friendly format. Dr. Lack has accomplished that and more by assembling an outstanding cadre of contributors. This book should be a foundation in every serious clinician's collection of resources."
