'This is a practical guide that helps clinicians identify, conceptualize, and differentiate obsessive-compulsive spectrum disorders (OCRDs)—which can meaningfully inform treatment planning. A must have resource for therapists who see young people with OCRDs.'Joseph F. McGuire, Ph.D.James C. Harris, MD., professor in Developmental Neuropsychiatry & Neurosciences Research, Division of Child & Adolescent Psychiatry, Department of Psychiatry & Behavioral Sciences, Johns Hopkins University School of Medicine'An essential resource for clinicians, students and academics looking to understand OCRDs in childhood. Seamlessly blending easy to read and accessible information with depth of scientific knowledge, this book offers a comprehensive exploration of OCRDs, their common threads and distinctive nuances, developmental presentations, comorbidity, and treatment. Whether you're just stepping into the field or seeking fresh insights, this book has new knowledge for everyone.'Carly Johnco, associate professor, Ph.D., School of Psychological Sciences, Macquarie University (Sydney, Australia)'Drs. Storch and Guzick are well established leaders in the field of childhood OCD and related disorders, and have gathered together an excellent set of equally well regarded chapter authors. The book’s focus is much broader and more inclusive than other texts available, and should be an indispensable resource for students, clinicians, and researchers for years to come.'Caleb W. Lack, Ph.D. (he/him), professor of psychology, program coordinator, M.A. in Counseling Psychology and Practicum Coordinator, Counseling Psychology/MFT, University of Central Oklahoma'This fabulous book offers a cutting edge tour of OCRDs in children. Novice clinicians will gain a foundational overview of these challenging disorders, and seasoned clinicians will broaden their expertise and fine-tune their approach. This book will also help investigators advance much-needed research in pediatric OCRDs, several of which are woefully understudied. What a fantastic resource!'Jedidiah Siev, Swarthmore College'In this indispensable, comprehensive, and up-to-date book, Drs. Storch and Guzik assembled a cadre of international experts to provide a clear, balanced, and highly informative review of the Obsessive-Compulsive and Related Disorders (OCRDs) diagnostic category in youth. Uniquely, the book transcends existing OCRDs and critically examines additional conditions that may share features with OCD, including misophonia, hoarding and tic disorders, and even sensory dysregulation and health anxiety. This unique, authoritative book is an essential resource for pediatric mental health professionals.'Amitai Abramovitch, PhD, associate professor, Texas State University 'This book is a necessary addition for all those who work in mental health with children and adolescents, contributing to the understanding of areas that are still under study and development. The information provided, precise and clear, transforms this clinical guide into an undoubted theoretical and practical reference, which should be a basic reading recommended for therapists who want to nourish their knowledge and delve into topics of high interest today, both in research and in clinical practice.'Tomás Miño Landon, IOCDF professional member. director diploma in Obsessive Compulsive Disorder ADIPA, Chile. director HablemosdeTOC Chile. director Chilean Network of OCD Specialists'This splendid compilation is a resource that only comes around once a decade. Veterans of the field will delight in updates and guidance while serving as a starting point I could have only hoped for as a new clinician. While it is centered on children, much applies to adults. Its coverage of disgust, sensory dysregulation, tics, and significantly more provides insight for clinical practice so that already effective treatments can excel even further past current limitations. I joyfully welcome this book.' Justin K. Hughes, MA, LPC—therapist, speaker, and writer at www.justinkhughes.com
