Clinical Psychometrics is an introduction to the long-term attempt to measure the psychiatric dimension of dementia, schizophrenia, mania, depression, anxiety, neuroticism, extraversion/introversion and health-related quality of life. The two psychometric procedures, classical factor analysis and modern item-response models, are presented for readers without any requirement for particular mathematical or statistical knowledge. The book is unique in this attempt and provides helpful background information for the dimensional approach that is being used in the forthcoming updates to the diagnostic classification systems, ICD-11 and DSM-5. The book is written for everyone who is interested in the origins and development of modern psychiatry, and who wants to be familiar with its practical possibilities; how it is possible to compare different individuals with each other, how one may determine the boundary between what is normal and what is disease, or how one may assess the clinical effect of the various forms of treatment, available to present day psychiatry.

Clinical Psychometrics can be defined as a discipline that deals with the definition and measurement of clinical constructs. Among its interests, it includes dimensions, such as skills, behavior, psychopathology, quality of life, and personality. Indeed, this discipline focuses on individual differences, the theory of measurement, the construction of measure instruments and their application in an international context. Clinical Psychometrics can be considered as an essential tool in many fields of research related to psychological and psychiatric interventions: for example, it is useful for diagnostic assessment (in various fields, including clinical and forensic areas), for the design and evaluation of specific psychological and pharmacological treatments. Therefore, Clinical Psychometrics is an applied discipline using psychometric tools to develop evidence-based type procedures relating to the understanding and improvement of the psychological conditions of individuals. This Research Topic on “Clinical Psychometrics” is interested in several aspects of measurement of psychological variables, focusing on the two fundamental paradigmatic aspects of the discipline, the Classical Test Theory and the Item Response Theory. This Research Topic seeks to stimulate a scientific debate between psychotherapists and psychometricians in this area. It could have applicative fallouts, such as designing trans-cultural studies in order to: 1) investigate the invariance of new instruments for measuring clinical variables; 2) test the invariance of existing instruments used in clinical research; 3) develop more refined measure instruments for the evaluation of clinical dimensions, similarly to work conducted by the Obsessive Compulsive Cognitions Working Group in identifying domains considered central to OCD and developing the 87-item Obsessive Beliefs Questionnaire; 4) evaluate therapeutic outcomes and processes (such as, states stress, psychological distress, psychological adjustment to illness, health-related quality of life, mood disorders, sexual functioning, etc.). The goal of this Research Topic is to disseminate a culture of integration between “psychometric model” and “clinical model”, promoting the scientific debate about the deepening of the existing methods and/or the proposal of new methods capable of combining clinical significance with quantitative rigor. This Research Topic welcomed all types of articles, with the exception of case reports. We were particularly interested in: 1. Systematic reviews shedding new lights on the psychometric properties of the most used psychological measures in clinical psychology, neuroscience, psychiatry, psychosomatics, etc.; 2. Guidelines and suggestions on the correct use and gold standards in psychological assessment in the form of research studies and brief reports on the development of new measures and adaptation of existing ones.

The edition of this classic text has been completely revised and updated, taking into account recent developments in the field of psychometrics. Part 1 of Modern Psychometrics outlines the background, history and controversies surrounding psychological testing. Part 2 provides a practical guide for developing a psychometric test. Modern Psychometrics forms the ideal companion for those studying for the British Psychological Society's Certificates of Competence in Testing

In Psychometrics, R Michael Furr and Verne R Bacharach centre their presentation of material around a conceptual understanding of psychometric issues, such as validity and reliability, and on purpose rather than procedure, the ′why′ rather than the ′how to′. By emphasizing concepts over mathematical proofs and by focusing on practical significance, this book will assist students in appreciating not just how measurement problems can be addressed but why it is important to address them. The Second Edition has been thoroughly revised to improve the clarity and accessibility of key concepts and to increase the depth of discussions. Many new tables and figures have been added and the references have been significanly updated and expanded. An entirely new chapter on confirmatory factor analysis has also been added to this edition. This new chapter focuses on the use of CFA to evaluate measurement models, including in-depth discussion of the logic and interpretation of the process. Key features of this volume: - presents information in a clear, easy-to-read, conversational style: the authors introduce concepts in a way that is accessible to non-professionals without sacrificing the academic integrity of the material - highlights practical applications: intended to enhance readers′ appreciation of the importance of psychometrics, the book provides examples that will resonate with students - offers an up-to-date treatment of topics in psychometrics: the book offers readers the most contemporary views of topics in psychometrics available in the non-technical psychometric literature - introduces statistical procedures in the context of their use rather than in a separate chapter: the authors integrate statistics with a discussion of their use as tools to solve particular psychometric problems, encouraging a more complete understanding of both.

This book 'Essays on Contemporary Psychometrics' provides an overview of contemporary psychometrics, the science devoted to the advancement of quantitative measurement practices in psychology, education and the social sciences. The volume consists of four parts, each having several chapters on cutting-edge work in the field. Part I, General Perspectives on Psychometrics, includes expert views on topics such as psychological models vs. measurement models, using tests in decision making, artificial intelligence, and psychometric network models. Part II, Factor Analysis and Classical Test Theory, the type of psychometrics that is still used most often in the social and behavioral sciences, includes state-of-the-art contributions on test-score reliability, change-score reliability, handling missing data in principal component analysis, test equating, and conditional standard errors of measurement. Part III, Item Response Theory, the leading form of psychometrics in modern educational measurement, includes discussions of sampling from many conditional distributions, transparent score reporting, nonparametric item response theory, and targeted testing. Part IV, New Psychometrics, discusses recently developed ideas beyond classical test theory and item response theory, including topics related to computer adaptive testing, response-time modelling, validity indices, diagnostic classification models, and the sparse latent class model for ordinal measurements. Together, these four parts provide an overview of the current state-of-the-art in psychometrics in educational measurement. They are a valuable source of information for graduate students who (intend to) study psychometrics and need an overview of the field, and for researchers interested in the current developments in the field.
