“No other book explains so well the value of using a unified framework based on clinical assessment, systematic measurement, and clinical science to guide health and mental health decision-making and practice – and the dangers of not doing so. The best and most authoritative book on this topic by far.” - Eric J. Mash, University of Calgary, Alberta, Canada “The field of clinical psychology has long awaited a new, authoritative text on clinical assessment. This book should quickly become the definitive reference for graduate courses in clinical and personality assessment. It is supremely rich in valuable insight, instruction, and guidance for the student, clinician, and researcher.” - Thomas A. Widiger, 2009 recipient of the Distinguished Scientist Award by the Society for the Science of Clinical Psychology“This book is sorely needed. The authors provide guidelines for evaluating the psychometric properties of tests and measures, discuss maximizing clinical decision making and utility, and instruct the reader on how to evaluate statistical methods in clinical assessment research. This is a book I will use the next time I teach a class in psychological measurement and psychometrics.” - Tim Trull, University of Missouri, USA "Written by prominent scholars in the field, this book is essential reading for scientifically minded clinicians. Whether researchers or practitioners, students or faculty, clinical psychologists of all kinds can improve patient care by integrating the concepts discussed throughout this book into their daily work. [This book] is not the sole resource for this material, but it is perhaps the most concise and inclusive to date. The book warrants high praise and a clear, positive recommendation." -Michael L. Thomas, University of California San Diego, USA, in PsycCRITIQUES
