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.

Written by a foremost expert in the field, this hands-on, evidence-based guide describes how to conduct a comprehensive forensic neuropsychological evaluation and provide expert testimony. All steps are covered--from selecting, scoring, and interpreting tests to writing reports and responding to cross-examination--with special attention to assessing noncredible performance. The book identifies seven common flaws of forensic neuropsychological reports and shows how to avoid them. Excerpts from testimony transcripts illustrate ways neuropsychologists can protect their reports from attack. Also featured are case illustrations and a sample report.

Thoroughly covering the "why" and "how" of validity testing with children and adolescents, this book is edited and written by leaders in the field. Feigning or noncredible effort during psychological and neuropsychological assessments can have considerable repercussions for diagnosis, treatment, and use of resources. Practical guidance is provided for detecting and managing noncredible responding, including vivid case material. The reasons that children may feign during testing are also explored. Along with information relevant to all assessment settings, the book features specific chapters on educational, medical, sport-related, forensic, and Social Security Disability contexts.

The United States Social Security Administration (SSA) administers two disability programs: Social Security Disability Insurance (SSDI), for disabled individuals, and their dependent family members, who have worked and contributed to the Social Security trust funds, and Supplemental Security Income (SSSI), which is a means-tested program based on income and financial assets for adults aged 65 years or older and disabled adults and children. Both programs require that claimants have a disability and meet specific medical criteria in order to qualify for benefits. SSA establishes the presence of a medically-determined impairment in individuals with mental disorders other than intellectual disability through the use of standard diagnostic criteria, which include symptoms and signs. These impairments are established largely on reports of signs and symptoms of impairment and functional limitation. Psychological Testing in the Service of Disability Determination considers the use of psychological tests in evaluating disability claims submitted to the SSA. This report critically reviews selected psychological tests, including symptom validity tests, that could contribute to SSA disability determinations. The report discusses the possible uses of such tests and their contribution to disability determinations. Psychological Testing in the Service of Disability Determination discusses testing norms, qualifications for administration of tests, administration of tests, and reporting results. The recommendations of this report will help SSA improve the consistency and accuracy of disability determination in certain cases.

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.

The Compendium is an essential guidebook for selecting the right test for specific clinical situations and for helping clinicians make empirically supported test interpretations. BL Revised and updated BL Over 85 test reviews of well-known neuropsychological tests and scales for adults BL Includes tests of premorbid estimation, dementia screening, IQ, attention, executive functioning, memory, language, visuospatial skills, sensory function, motor skills, performance validity, and symptom validity BL Covers basic and advanced aspects of neuropsychological assessment including psychometric principles, reliability, test validity, and performance/symptom validity testing

This compendium gives an overview of the essential aspects of neuropsychological assessment practice. It is also a source of critical reviews of major neuropsychological assessment tools for the use of the practicing clinician.
