This book declines to take for granted the widespread assumption that existing psychometric procedures provide scientific measurement. The currently fashionable concepts of measurement within psychology -- operationalism and representationalism -- are critically examined, and the classical view, that measurement is the assessment of quantity, is defended. Within this framework, it is shown how conjoint measurement can be used to test the hypothesis that variables are quantitative. This theme is developed in detail using familiar psychological examples, such as Thurstone's law of comparative judgment, multidimensional scaling, and Coombs' theory of unfolding.

Primarily intended for undergraduate and postgraduate students of psychology, the book aims to provide a succinct yet reasonably compre-hensive account of psychological measurement techniques (psychometry) in a single volume. Written in a lucid style with the author’s rich teaching experience, the book focuses on the technique of development and use of psychological tests and scales. It also describes essential features and steps to be followed in constructing a psychological test. The book, divided into three parts, covers psychophysical methods, psychological scaling and test methods, and some elementary but essential statistical concepts used in the measurement and interpretation of psychological test data. Besides psychology students, the book will also be useful for undergraduate and postgraduate students of education, and professionals in the field of psychology and education.

This text is a vital resource for those with little or no prior knowledge of computing or statistics to aid in the development of reliable and valid tests and scales for assessment or research purposes. It serves as a clear, concise and jargon-free primer for all those embarking in fieldwork or research analysis. The book contains detailed guidelines for locating and constructing psychological measures, including descriptions of popular psychological measures and step-by-step instructions for composing a measure, entering data, and computing reliability and validity of test results. Advanced techniques such as factor analysis, analysis of covariance, and multiple regression analysis are presented for the beginner. This new edition has been revised throughout and includes updated statistical test procedures in line with the new version of SPSS and the inclusion of current academic articles. It serves as an invaluable resource for undergraduates and postgraduates across the behavioral and social sciences, as well as professionals in related disciplines, including those working in management and medical sciences.

This is a careful and thoroughly updated revision of the most highly acclaimed and successful undergraduate text in testing over the last fifteen years. PSYCHOLOGICAL TESTING AND ASSESSMENT examines the philosophical, historical, and methodological foundations of psychological testing, assessment, and measurement, while helping students appreciate their benefits and pitfalls in practice.

Introductory texts on psychological testing and evaluation historically are not in short supply. Typically, however, such texts have been relatively superficial in their discussion of clinical material and have focused primarily on the theoretical and psychometric properties of indi vidual tests. More practical, clinically relevant presentations of psychological instruments have been confined to individual volumes with advanced and often very technical information geared to the more sophisticated user. Professors in introductory graduate courses are often forced to adopt several advanced texts to cover the material, at the same time helping students wade through unnecessary technical information in order to provide a basic working knowl edge of each test. Understanding Psychological Assessment is an attempt to address these concerns. It brings together into a single volume a broad sampling of the most respected instruments in the psychologist's armamentarium along with promising new tests of cognitive, vocational, and personality functioning. Additionally, it presents the most updated versions of these tests, all in a practical, clearly written format that covers the development, psychometrics, administra tive considerations, and interpretive hypotheses for each instrument. Clinical case studies allow the reader to apply the interpretive guidelines to real clinical data, thereby reinforcing basic understanding of the instrument and helping to insure that both the student and practi tioner can actually begin to use the test. Understanding Psychological Assessment includes cognitive and personality tests for adults, children, and adolescents, as well as chapters on the theory of psychological measurement and integrated report writing.
