Mokken Scale Analysis collectively refers to a set of methods to examine the fit of data to two nonparametric Item Response Theory (IRT) models known as the Monotone Homogeneity Model (MHM) and the Double Monotonicity Model (DMM). As nonparametric IRT models, MHM and DMM are, compared to their parametric counterparts, easier to fit to the noisy data that social science researchers usually work with. Furthermore, the logic behind these models is a lot easier to grasp by researchers who do not have a strong background in algebra. This book is an introductory treatment of the topic with examples from the field of language assessment and research. It describes the basics of MSA and includes step-by-step tutorials to help the readers run the analyses with the R package mokken. Furthermore, case studies are reported to illustrate the concepts introduced throughout the book. The book is comprehensive and reader-friendly and can be followed by most empirical researchers in the social sciences. It is suitable for all researchers and practitioners in the fields of behavioral and social sciences who are engaged in test and scale development. It is an easy-to-use manual that covers everything that you need to know to apply Mokken scaling confidently.

This handbook provides an overview of major developments around diagnostic classification models (DCMs) with regard to modeling, estimation, model checking, scoring, and applications. It brings together not only the current state of the art, but also the theoretical background and models developed for diagnostic classification. The handbook also offers applications and special topics and practical guidelines how to plan and conduct research studies with the help of DCMs. Commonly used models in educational measurement and psychometrics typically assume a single latent trait or at best a small number of latent variables that are aimed at describing individual differences in observed behavior. While this allows simple rankings of test takers along one or a few dimensions, it does not provide a detailed picture of strengths and weaknesses when assessing complex cognitive skills. DCMs, on the other hand, allow the evaluation of test taker performance relative to a potentially large number of skill domains. Most diagnostic models provide a binary mastery/non-mastery classification for each of the assumed test taker attributes representing these skill domains. Attribute profiles can be used for formative decisions as well as for summative purposes, for example in a multiple cut-off procedure that requires mastery on at least a certain subset of skills. The number of DCMs discussed in the literature and applied to a variety of assessment data has been increasing over the past decades, and their appeal to researchers and practitioners alike continues to grow. These models have been used in English language assessment, international large scale assessments, and for feedback for practice exams in preparation of college admission testing, just to name a few. Nowadays, technology-based assessments provide increasingly rich data on a multitude of skills and allow collection of data with respect to multiple types of behaviors. Diagnostic models can be understood as an ideal match for these types of data collections to provide more in-depth information about test taker skills and behavioral tendencies.

This is the second edition of an introductory text that describes the principles of invariant measurement; how invariant measurement can be achieved using Rasch measurement theory; and how to use invariant measurement to solve a variety of measurement problems in the social, behavioral, and health sciences. Rasch models are used throughout the text, but brief comparisons of Rasch models to other item response theory (IRT) models are also provided. Written with students in mind, this new edition was class-tested to help maximize accessibility. Chapters open with an introduction and close with a discussion and summary. All chapters have been updated from the first edition, and a new chapter on explanatory Rasch models has been added. Features include numerous examples and exercises to demonstrate the main issues addressed in each chapter. Key terms are defined when first introduced and included in a helpful end-of-text glossary. This book also benefits from online materials which include the data sets used in the book, sample syntax files for running the Facets program, Excel files for creating item and person response functions, and links to related websites. This book will act as a supplementary text for graduate or advanced undergraduate courses on measurement or test theory, IRT, scaling theory, psychometrics, advanced measurement techniques, research methods, or evaluation research taught in education, psychology, and other social and health sciences. It will also appeal to practitioners and researchers in these fields who develop or use scales and instruments. Only a basic mathematical level is required, including a basic course in statistics, ensuring it is an accessible resource for students and researchers alike.

The field of language testing and assessment has recognized the importance and underlying theoretical and practical underpinnings of language assessment literacy (LAL), an area that is gradually coming to prominence. This book addresses issues that promote the concept of LAL for language research, teaching, and learning, covering a range of topics. It brings together 14 chapters based on high-stakes and classroom-based studies authored by academics, professionals and researchers in the field. The text examines diverse issues through a multifaceted approach, presenting high-quality contributions that fill a gap in a research area that has long been in need of theoretical and empirical attention.

A book which summarizes many of the recent advances in the theory and practice of achievement testing, in the light of technological developments, and developments in psychometric and psychological theory. It provides an introduction to the two major psychometric models, item response theory and generalizability theory, and assesses their strengths for different applications. The book closes with some speculations about the future of achievement tests for the assessment of individuals, as well as monitoring of educational progress. `...the book contains valuable information for both beginners and for advanced workers who want an overview of recent work in achievement testing.' -- The Journal of the American Statistical A

This is the first e-book that presents some insights into the construction of Mokken scales with complex survey data, and, in particular, the estimation of Mokken's scalability coefficients - Hij, Hi, and H - with binary responses. Every day, researchers work with complex samples selected from finite populations of interest to make inferences about population parameters. However, in many situations these samples are assumed as SRS samples. Serious consequences have been reported in the complex survey data literature; when this assumption is considered. I invite you to find out a little more about some relevant contributions to the development of the Psychometry under complex sampling designs, as highlighted in this e-book. Keywords: Mokken scaling, Mokken scale analysis, complex data, Complex Mokken, design effect, clustering, sampling weights, stratification, clustered samples, variance estimation, point estimation, large-scale educational surveys, Jackknife resampling technique, Non Parametric Item Response Theory.

Health Measurement Scales is the ultimate guide to appraising, developing, and validating measurement scales that are used in the health sciences. Written in a clear and practical style, this guide enables clinicians and researchers to both develop scales to measure subjective states and non-tangible health outcomes, as well as evaluate and differentiate among existing tools. Topics presented in the order that scales are constructed: how the individual items are developed, biases that can affect responses, various response options, how to select the best items in the set, how to combine them into a scale; and finally how to determine the reliability and validity of the scale. Fully updated to reflect recent developments in the field and the latest survey methods. The new edition contains updated information on generalizability theory and item response theory, and integration of qualitative research methods into scale design and testing. Including guidelines, appendices and checklists, this useful book is a must-read for any practitioner dealing with any kind of subjective measurement.
