Description : In this book, Kraemer presents a systematic, objective methodology by which to determine the effectiveness of medical tests. She shows clearly and concisely how to define statistical terms and approaches consistently from study to study, how to stipulate statistical assumptions underlying various approaches, how to check for empirical validity and how to judge the robustness of statistical outcomes, resulting in models that integrate many different approaches and extend the strengths of each....

Description : The use of clinical and laboratory information to detect conditions and predict patient outcomes is a mainstay of medical practice. Modern biotechnology offers increasing potential to develop sophisticated tests for these purposes. This book describes the statistical concepts and techniques for evaluating the accuracy of medical tests. Worked examples include applications to cancer biomarker studies, prospective disease screening studies, diagnostic radiology studies and audiologytesting studies. The statistical methodology can be broadly applied for evaluating classifiers and to problems beyo....

Description : The new and updated edition of this book explains the key steps in planning and executing diagnostic test accuracy studies in dementia, serving as an introduction to the topic with clear explanations of difficulties and pitfalls. It has been fully revised in light of developments over the past 5 years and includes STARD publications which have appeared since the first edition as well as the use of biomarkers of cognitive disorders as increasingly enshrined in diagnostic criteria. The book covers the presentation of study results in terms of measures of discrimination, taking examples from studies in dementia looking at various diagnostic methods including cognitive instruments, neuroimaging, and biochemical studies. The book continues to reflect the author’s own experience in diagnostic test accuracy studies, particularly in the sphere of cognitive screening instruments.. Diagnostic Test Accuracy Studies in Dementia encourages clinicians to adopt a pragmatic approach to diagnostic test accuracy studies rooted in day-to-day clinical practice....

Description : Preeminent clinical child and adolescent psychological scientists offer an agenda for future research in this compendium of thought pieces. On a wide range of topics including ADHD, depression, self-injury, emotion regulation, conduct problems, addictions, clinical assessment and therapy, and many more, scientists review the current state of the literature and offer specific recommendations for what investigators next need to tackle to reduce mental illness among youth. Chapters include a discussion of theories and methods in clinical child and adolescent psychology, current funding priorities, and the intersection of traditional clinical psychology research with the burgeoning field of psychological neuroscience. This book is an essential resource for classes on clinical child and adolescent psychopathology and treatment. It also provides a unique guide for undergraduate and early graduate students who are determining how to start their research careers in the field. All of the chapters in this book were originally published as articles in the Journal of Clinical Child and Adolescent Psychology....

Description : Useful in many areas of medicine and biology, Bayesian methods are particularly attractive tools for the design of clinical trials and diagnostic tests, which are based on established information, usually from related previous studies. Advanced Bayesian Methods for Medical Test Accuracy begins with a review of the usual measures such as specificity, sensitivity, positive and negative predictive value, and the area under the ROC curve. Then the scope expands to cover the more advanced topics of verification bias, diagnostic tests with imperfect gold standards, and those for which no gold standard is available. Promoting accuracy and efficiency of clinical trials, tests, and the diagnostic process, this book: Enables the user to efficiently apply prior information via a WinBUGS package Presents many ideas for the first time and goes far beyond the two standard references Integrates reader agreement with different modalities—X-ray, CT Scanners, and more—to study their effect on medical test accuracy Provides practical chapter-end problems Useful for graduate students and consulting statisticians working in the various areas of diagnostic medicine and study design, this practical resource introduces the fundamentals of programming and executing BUGS, giving readers the tools and experience to successfully analyze studies for medical test accuracy....
