"This scholarly yet very accessible book is a 'must read' for anyone involved in assessment and treatment in mental health. While it is now widely accepted that mental health problems fall along continuous dimensions rather than fitting into discrete categories, clinical implementation of this new understanding of psychopathology remains challenging. Bringing together dozens of experts with varying perspectives, this groundbreaking book launches a much-needed discussion of dimensional diagnosis. Topics include not only assessment, diagnosis, and treatment, but also epidemiology, clinical training, genetics, neurobiology, stigma, overlap and distinctions between personality and psychopathology, and incorporating more diverse and underrepresented populations into work in this area."--Lee Anna Clark, PhD, William J. and Dorothy K. O’Neill Professor Emerita, Department of Psychology, University of Notre Dame"Dimensional diagnosis sounds good, in principle. Finally, here is a volume that helps make it practical. This book is a go-to resource for all. It addresses everything from the conceptual basis of dimensional diagnoses to measurement considerations to clinical implications--and even how to train the next generation of scientists and practitioners."--Avshalom Caspi, PhD, Edward M. Arnett Distinguished Professor of Psychology and Neuroscience, Duke University; Professor of Personality Development, Institute of Psychiatry, Psychology, and Neuroscience, King’s College London, United Kingdom"The move from categorical to dimensional models of psychopathology is perhaps the most significant change in psychiatric nosology in the past quarter century. This outstanding volume is the first to explore the implications of this shift with such clarity, realism, and depth. The editors--two of the field's most innovative scientist-clinicians--have brought together leading international experts to address the urgent clinical questions arising from the DSM and ICD revisions. The volume combines conceptual sophistication with remarkable pragmatism. It offers realistic, implementable guidance for clinicians, while at the same time illuminating the broader intellectual significance of the dimensional approach. This is a rare achievement--a book that is both indispensable for daily practice and transformative in its influence. Destined to become a classic."--Peter Fonagy, CBE, FMedSci, FBA, FAcSS, Head, Division of Psychology and Language Sciences, University College London, United Kingdom-
