Evaluation of Diagnostic Systems: Methods from Signal Detection Theory addresses the many issues that arise in evaluating the performance of a diagnostic system, across the wide range of settings in which such systems are used. These settings include clinical medicine, industrial quality control, environmental monitoring and investigation, machine and metals inspection, military monitoring, information retrieval, and crime investigation. The book is divided into three parts encompassing 11 chapters that emphasize the interpretation of diagnostic visual images by human observers. The first part of the book describes quantitative methods for measuring the accuracy of a system and the statistical techniques for drawing inferences from performance tests. The subsequent part covers study design and includes a detailed description of the form and conduct of an image-interpretation test. The concluding part examines the case study of a medical imaging system that serves as an example of both simple and complex applications. In this part, three mammographic modalities are used: industrial film radiography, low-dose film radiography, and xeroradiography. The case study focuses on the overall reliability of accuracy indices made by its main components, that is, the variabilities across cases, across readers, and within individual readers. The supplementary texts provide study protocols, a computer program for processing test results, and an extensive list of references that will assist the reader in applying those evaluative methods to diagnostic systems in any setting. This book is of value to scientists and engineers, as well as to applied, quantitative, or experimental psychologists who are engaged in the study of the human processes of discrimination and decision making in either perceptual or cognitive tasks.

Fundamentals of Evaluation and Diagnostics of Welded Structures provides an essential guide to the key principles and problems involved in the analysis of welded structures. Chapter one discusses design issues, key equations and calculations, and the effects of varied heat sources in relation to the temperature field in welding. Chapter two goes on to explore welding stresses and strains. Fracture mechanics and the load-carrying capacity of welded structures are the focus of chapter three. Chapter four considers diagnostics and prediction of the residual life of welded structures, whilst acoustic emission techniques for the analysis of welded structures are reviewed in chapter five. Finally, chapter six supplies supplementary information on numerical techniques and other tests for welded structures. With its distinguished author and detailed coverage, Fundamentals of evaluation and diagnostics of welded structures is an indispensable guide for welding and structural engineers as well as those researching this important topic.

Statistical evaluation of diagnostic performance in general and Receiver Operating Characteristic (ROC) analysis in particular are important for assessing the performance of medical tests and statistical classifiers, as well as for evaluating predictive models or algorithms. This book presents innovative approaches in ROC analysis, which are relevant to a wide variety of applications, including medical imaging, cancer research, epidemiology, and bioinformatics. Statistical Evaluation of Diagnostic Performance: Topics in ROC Analysis covers areas including monotone-transformation techniques in parametric ROC analysis, ROC methods for combined and pooled biomarkers, Bayesian hierarchical transformation models, sequential designs and inferences in the ROC setting, predictive modeling, multireader ROC analysis, and free-response ROC (FROC) methodology. The book is suitable for graduate-level students and researchers in statistics, biostatistics, epidemiology, public health, biomedical engineering, radiology, medical imaging, biomedical informatics, and other closely related fields. Additionally, clinical researchers and practicing statisticians in academia, industry, and government could benefit from the presentation of such important and yet frequently overlooked topics.

While the ABPN has now supplied such standards for psychiatry,psychiatric interviewing instruction has not been standardized inthe US or in other countries. Similarly, the few psychiatricinterviewing books available are written in textbook form, oftenlong and often from the subpecialty perspective (e.g. psychodynamicinterviewing). Critically, no interviewing guides to datetake a true biopsychosocial perspective. That is, they limitthemselves to “interviewing” as an isolated techniquedivorced from full patient assessment, which for quality patientcare must include the interface of psychological and socialcomponents with biological components. Similarly, fewinterviewing texts are fully integrated with DSM/ICD categoricaldiagnostic schemata, even though these descriptive diagnosticsystems represent the very core of our clinical language—thelingua franca of the mental health professions. Without good descriptive diagnoses there cannot be adequatecommunication of clinical data among providers. The proposed book will meet this need for training inbiopsychosocial assessment and diagnosis. The patient interview is at the heart of psychiatricpractice. Listening and interviewing skills are the primarytools the psychiatrist uses to obtain the information needed tomake an accurate diagnosis and then to plan appropriatetreatment. The American Board of Psychiatry and Neurology andthe Accrediting Council on Graduate Medical Educationidentify interviewing skills as a core competency forpsychiatric residents. The Psychiatric Interview: evaluation and diagnosis is anew and modern approach to this topic that fulfills the need fortraining in biopsychosocial assessment and diagnosis. Itmakes use of both classical and new knowledge of psychiatricdiagnosis, assessment, treatment planning and doctor-patientcollaboration. Written by world leaders in education, the book isbased on the acclaimed Psychiatry Third Edition byTasman, Kay et al, with new chapters to address assessment inspecial populations and formulation. The psychiatricinterview is conceptualized as integrating the patient's experiencewith psychological, biological, and environmental components of theillness. This is an excellent new text for psychiatry residents at allstages of their training. It is also useful for medicalstudents interested in psychiatry and for practicingpsychiatrists who may wish to refresh their interviewingskills.

Assessment and Therapy is a derivative volume of articles pulled from the award-winning Encyclopedia of Mental Health, presenting a comprehensive overview of assessing and treating the many disorders afflicting mental health patients, including alcohol problems, Alzheimer's disease, depression, epilepsy, gambling, obsessive-compulsive disorder, phobias, and suicide. According to 1990 estimates, mental disorders represent five of the ten leading causes of disability. Among "developed" nations, including the United States, major depression is the leading cause of disability. Also near the top of these rankings are bipolar depression, alcohol dependence, schizophrenia, and obsessive-compulsive disorder. In addition, mental disorders are tragic contributors to mortality, with suicide perennially representing one of the leading preventable causes of death worldwide. Assessment and Therapy describes the impact of mental health on the individual and society and illustrates the factors that aid positive mental health. Twenty-six peer-reviewed articles written by more than 40 expert authors include essential material on assessing and treating schizophrenia, manic-depressive illness, major depression, anxiety disorders, and other mental illnesses. Professionals and libraries will find this timely work indispensable.
