Validity Assessment In Clinical Neuropsychological Practice

Practical and comprehensive, this is the first book to focus on noncredible performance in clinical contexts. Experts in the field discuss the varied causes of invalidity, describe how to efficiently incorporate validity tests into clinical evaluations, and provide direction on how to proceed when noncredible responding is detected. Thoughtful, ethical guidance is given for offering patient feedback and writing effective reports. Population-specific chapters cover validity assessment with military personnel; children; and individuals with dementia, psychiatric disorders, mild traumatic brain injury, academic disability, and other concerns. The concluding chapter describes how to appropriately engage in legal proceedings if a clinical case becomes forensic. Case examples and sample reports enhance the book's utility.

This is the first book devoted to the topic of validity assessment in rehabilitation contexts and is written by two board certified psychologists with extensive experience in clinical neuropsychology and rehabilitation psychology. This book describes (a) why validity assessment is important, (b) validity assessment methods, and (c) special topics related to validity assessment in rehabilitation psychology (e.g., managing invalid presentations, mild traumatic brain injury, forensic and disability applications, ethical considerations). Although primarily intended for the rehabilitation psychologist who is new to the topic of validity assessment, this book is also designed to be helpful to other rehabilitation specialists, students and trainees, and psychologists experienced in validity assessment, including neuropsychologists.

No other book reviews clinical neuropsychological assessment from an empirical psychometric perspective. In this completely revised and updated 2nd edition, the concepts and methods of psychometric neuropsychology are presented as a framework by which to evaluate current instruments. Newer methodologies and statistical techniques are discussed, such as meta analysis, effect size, confirming factor analysis and ecological validity. The explosion of research in this area since the publication of the first edition in 1989, has been incorporated, including a greatly expanded chapter on child assessment instruments. This volume is a must for the bookshelf of every clinical neuropsychologist as well as researchers and students. Anyone conducting forensic evaluations will especially find useful the information on reliability and validity when preparing for court appearances.

A Compendium of Neuropsychological Tests, Fourth Edition is one of the most well-established reference texts in neuropsychology. This newly-revised, updated, and expanded fourth edition provides a comprehensive overview of essential aspects of neuropsychological practice along with 100 test reviews of well-known neuropsychological tests for adults. The aim of the Compendium is to provide a comprehensive yet practical overview of the state of the field while also summarizing the evidence on the theoretical background, norms, reliability, and validity of commonly-used neuropsychological tests. Based on extensive review of the clinical and research literature in neuropsychology, neurology, and related disciplines, its comprehensive critical reviews of common neuropsychological tests and standardized scales include tests for premorbid estimation, dementia screening, IQ, attention, executive functioning, memory, language, visuospatial skills, sensory function, motor skills, performance validity, and symptom validity. Tables within each test review summarize important features of each test, highlight aspects of each normative dataset, and provide an overview of psychometric properties. This essential reference text also covers basic and advanced aspects of neuropsychological assessment with chapters on psychometric concepts and principles, reliability in neuropsychology, theoretical models of test validity, and an overview of critical concepts pertaining to performance and symptom validity testing and malingering. Of interest to neuropsychologists, clinical psychologists, educational psychologists, neurologists, and psychiatrists as well as trainees in these areas, this volume will aid practitioners in gaining a deeper understanding of fundamental assessment concepts in neuropsychology while also serving as an essential guidebook for selecting the right test for specific clinical situations and for helping clinicians make empirically-supported test interpretations.

Evidence-based practice has become the benchmark for quality in healthcare and builds on rules of evidence that have been developed in psychology and other health-care disciplines over many decades. This volume aims to provide clinical neuropsychologists with a practical and approachable reference for skills in evidence-based practice to improve the scientific status of patient care. The core skills involve techniques in critical appraisal of published diagnostic-validity or treatment studies. Critical appraisal skills assist any clinician to evaluate the scientific status of any published study, to identify the patient-relevance of studies with good scientific status, and to calculate individual patient-probability estimates of diagnosis or treatment outcome to guide practice. Initial chapters in this volume review fundamental concepts of construct validity relevant to the assessment of psychopathology and cognitive abilities in neuropsychological populations. These chapters also summarize exciting contemporary development in the theories of personality and psychopathology, and cognitive ability, showing a convergence of theoretical and clinical research to guide clinical practice. Conceptual skills in interpreting construct validity of neuropsychological tests are described in detail in this volume. In addition, a non-mathematical description of the concepts of test score reliability and the neglected topic of interval estimation for individual assessment is provided. As an extension of the concepts of reliability, reliable change indexes are reviewed and the implication of impact on evidence-based practice of test scores reliability and reliable change are described to guide clinicians in their interpretation of test results on single or repeated assessments. Written by some of the foremost experts in the field of clinical neuropsychology and with practical and concrete examples throughout, this volume shows how evidence-based practice is enhanced by reference to good theory, strong construct validity, and better test score reliability.

Ecological validity, the functional and predictive relationship between a patient's performance on a set of neuropsychological tests and their behavior in a variety of real-world settings, is emerging as a powerful tool. Since neuropsychological data were not designed to be ecologically valid, attempts to use the data in such a manner have been filled with pitfalls. The authors present a strong argument for reevaluating existing tests and/or developing new measurements. Special attention is given to specific functions such as the cognitive constructs of attention, perception, working memory, language, and executive function. Additional consideration is given to the assessment of special populations: children, minorities, substance abusers, elderly, and emotionally disturbed neurological populations. One area in which neuropsychology can lend tremendous assistance is in predicting a client's ability to resume activities of daily living, but more important, when a client can return to work. Ecological Validity of Neuropsychological Testing covers this issue extensively and details the role of vocational rehabilitation and the lack of exposure many within neuropsychology have to these specific needs of their clients.

This is a book for all neuropsychologists who are called upon to assess culturally different clients--with very few exceptions today, this means every neuropsychologist. In Minneapolis as in Oslo, migrant and refugee minorities raise assessment and test validity problems that cannot be ignored. To deal realistically with the problem of doing neuropsychological assessments without norms, Nell describes the principles of a "behavioral neuropsychology," and then sets out interview, test, and interpretation methods that will allow clinicians to produce valid and prognostically accurate assessments. For working neuropsychologists, this is an intensely practical, how-to-do-it book. But unlike other hands-on guides, it lays an impressive historical and theoretical foundation for the practice of cross-cultural neuropsychology. It thus speaks to serious practitioners who need to be certain that their assessment findings are not only correct, but also sufficiently well-grounded to stand up to professional scrutiny and to forensic testing in a court of law.
