Validity is the hallmark of quality for educational and psychological measurement. But what does quality mean in this context? And to what, exactly, does the concept of validity apply? These apparently innocuous questions parachute the unwary inquirer into a minefield of tricky ideas. This book guides you through this minefield, investigating how the concept of validity has evolved from the nineteenth century to the present day. Communicating complicated concepts straightforwardly, the authors answer questions like: What does ′validity′ mean? What does it mean to ′validate′? How many different kinds of validity are there? When does validation begin and end? Is reliability a part of validity, or distinct from it? This book will be of interest to anyone with a professional or academic interest in evaluating the quality of educational or psychological assessments, measurements and diagnoses.

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.

The Handbook of Psychoeducational Assessment is a practical guide for educational and psychological professionals using norm-referenced tests in the ability, achievement, and behavioral assessment of children. Written by key individuals involved in the construction and evolution of the most widely used tests, this book provides critical information on the nature and scope of commonly used tests, their reliability and validity, administration, scoring and interpretation, and on how the tests may differ and complement each other in their utility with specific populations. Part 1 of the Handbook of Psychoeducational Assessment focuses on ability assessment and the use of full battery intelligence tests as well as brief scales and short forms. Part 2 discusses achievement and the expanded role of psychologists in consultation with educators. Part 3 covers behavior assessment with special attention given to discussion of which tests are most suitable for assessing specific behavioral problems such as ADHD, anxiety, and depression. The final section recognizes the importance of context and person sensitive assessment practices, discussing cross-cultural assessment, neuropsychological assessment, and the usefulness of dynamic assessment for program planning and intervention delivery. Key Features: - Covers the most commonly used and newest assessment instruments - Describes the nature, scope, reliability, and validity of each test - Discusses the administration, scoring, and interpretation of tests - Provides empirical findings on patterns of performance with tested populations - Includes case studies to highlight the utility of specific tests for specific populations - Illustrates new developments in instrumentation and unique features - Covers the most commonly used and newest assessment instruments - Describes the nature, scope, reliability, and validity of each test - Discusses the administration, scoring, and interpretation of tests - Provides empirical findings on patterns of performance with tested populations - Includes case studies to highlight the utility of specific tests for specific populations - Illustrates new developments in instrumentation and unique features

This encyclopedia is the first major reference guide for students new to the field, covering traditional areas while pointing the way to future developments.

Validity is a clear, substantive introduction to the two most fundamental aspects of defensible testing practice: understanding test score meaning and justifying test score use. Driven by evidence-based and consensus-grounded measurement theory, principles, and terminology, this book addresses the most common questions of applied validation, the quality of test information, and the usefulness of test results. Concise yet comprehensive, this volume’s integrated framework is ideal for graduate courses on assessment, testing, psychometrics, and research methods as well as for credentialing organizations, licensure and certification entities, education agencies, and test publishers.

This book combines an overview of validity theory, trends in validation practices and a review of standards and guidelines in several international jurisdictions with research synthesis of the validity evidence in different research areas. An overview of theory is both useful and timely, in view of the increased use of tests and measures for decision-making, ranking and policy purposes in large-scale testing, assessment and social indicators and quality of life research. Research synthesis is needed to help us assemble, critically appraise and integrate the overwhelming volume of research on validity in different contexts. Rather than examining whether any given measure is “valid”, the focus is on a critical appraisal of the kinds of validity evidence reported in the published research literature. The five sources of validity evidence discussed are: content-related, response processes, internal structure, associations with other variables and consequences. The 15 syntheses included here, represent a broad sampling of psychosocial, health, medical and educational research settings, giving us an extensive evidential basis to build upon earlier studies. The book concludes with a meta-synthesis of the 15 syntheses and a discussion of the current thinking of validation practices by leading experts in the field.
