Adapting Psychological Tests and Measurement Instruments for Cross-Cultural Research provides an easy-to-read overview of the methodological issues and best practices for cross-cultural adaptation of psychological instruments. Although the development of cross-cultural test adaption methodology has advanced in recent years, the discussion is often pitched at an expert level and requires an advanced knowledge of statistics, psychometrics and scientific methodology. This book, however, introduces the history and concepts of cross-cultural psychometrics in a pedagogic and simple manner. It evaluates key ethical, cultural, methodological and legal issues in cross-cultural psychometrics and provides a guide to test adaptation, data analysis and interpretation. Written in an accessible manner, this book builds an understanding of the methodological, ethical and legal complexities of cross-cultural test adaptation and presents methods for test adaptation, including the basic statistical procedures for evaluating the equivalence of test versions. It would be the ideal companion for undergraduate students and those new to psychometrics.

In the past few decades the number of women entering graduate and professional schools has been going up and up, while the number of women reaching the top rung of the corporate and academic worlds has remained relatively stagnant. Why are so many women falling off the fast track?
In this timely book, Mary Ann Mason traces the career paths of the first generation of ambitious women who started careers in academia, law, medicine, business, and the media in large numbers in the 1970s and '80s. Many women who had started families but continued working had ended up veering off the path to upper management at a point she calls "the second glass ceiling." Rather than sticking to their original career goals, they allowed themselves to slide into a second tier of management that offers fewer hours, less pay, lower prestige, and limited upward mobility. Men who did likewise--entered the career world with high aspirations and then started families while working--not only did not show the same trend, they reached even higher levels of professional success than men who had no families at all.
Along with her daughter, an aspiring journalist, Mason has written a guide for young women who are facing the tough decision of when--and if--to start a family. It is also a guide for older women seeking a second chance to break through to the next level, as Mason herself did in academia. The book features anecdotes and strategies from the dozens of women they interviewed. Advice ranges from the personal (know when to say "no," the importance of time management) to the institutional, with suggestions for how the workplace itself can be changed to make it easier for ambitious working mothers to reach the top levels. The result is a roadmap of new choices for women facing the sobering question of how to balance a successful career with family.

This book demonstrates how to conduct latent variable modeling (LVM) in R by highlighting the features of each model, their specialized uses, examples, sample code and output, and an interpretation of the results. Each chapter features a detailed example including the analysis of the data using R, the relevant theory, the assumptions underlying the model, and other statistical details to help readers better understand the models and interpret the results. Every R command necessary for conducting the analyses is described along with the resulting output which provides readers with a template to follow when they apply the methods to their own data. The basic information pertinent to each model, the newest developments in these areas, and the relevant R code to use them are reviewed. Each chapter also features an introduction, summary, and suggested readings. A glossary of the text's boldfaced key terms and key R commands serve as helpful resources. The book is accompanied by a website with exercises, an answer key, and the in-text example data sets. Latent Variable Modeling with R: -Provides some examples that use messy data providing a more realistic situation readers will encounter with their own data. -Reviews a wide range of LVMs including factor analysis, structural equation modeling, item response theory, and mixture models and advanced topics such as fitting nonlinear structural equation models, nonparametric item response theory models, and mixture regression models. -Demonstrates how data simulation can help researchers better understand statistical methods and assist in selecting the necessary sample size prior to collecting data. -www.routledge.com/9780415832458 provides exercises that apply the models along with annotated R output answer keys and the data that corresponds to the in-text examples so readers can replicate the results and check their work. The book opens with basic instructions in how to use R to read data, download functions, and conduct basic analyses. From there, each chapter is dedicated to a different latent variable model including exploratory and confirmatory factor analysis (CFA), structural equation modeling (SEM), multiple groups CFA/SEM, least squares estimation, growth curve models, mixture models, item response theory (both dichotomous and polytomous items), differential item functioning (DIF), and correspondance analysis. The book concludes with a discussion of how data simulation can be used to better understand the workings of a statistical method and assist researchers in deciding on the necessary sample size prior to collecting data. A mixture of independently developed R code along with available libraries for simulating latent models in R are provided so readers can use these simulations to analyze data using the methods introduced in the previous chapters. Intended for use in graduate or advanced undergraduate courses in latent variable modeling, factor analysis, structural equation modeling, item response theory, measurement, or multivariate statistics taught in psychology, education, human development, and social and health sciences, researchers in these fields also appreciate this book's practical approach. The book provides sufficient conceptual background information to serve as a standalone text. Familiarity with basic statistical concepts is assumed but basic knowledge of R is not.

The practice of primary health care has expanded beyond the "traditional" medical model. Primary-care physicians and allied professionals are called upon more frequently to address parental concerns about develop mental delays, poor school performance, or behavioral problems. As a result, pediatricians, family practitioners, pediatric nurses, social workers, and speecManguage specialists are faced with the issue of developmental and psychological testing. The degree of the clinician's involvement in testing varies from interpretation of reports to performing screening or assessments. In many cases, the primary health care professional assumes the role of case manager. Unfortunately, cooperation between disciplines often has been lim ited because of poor communication, particularly in regard to develop mental and psychological testing, where acronyms, statistics, and jargon abound. Even professionals from mental health disciplines such as child psychiatrists or psychiatric social workers sometimes are overwhelmed. The purpose of this book, therefore, is to provide the clinician with practical information regarding developmental and psychological testing, thereby making the health care professional an "educated consumer. " This text does not simply describe how psychologists perform testing; rather, it provides information to help clinicians understand what the tests con tain, what their strengths and limitations are, and how they can be incorporated into practice."

Interpret the WISC V to help diagnose learning disabilities and to translate profiles of test scores to educational action The Wechsler Intelligence Scale for Children Fifth Edition (WISC V) is a valuable tool for assessing children and adolescents with learning disorders and Intelligent Testing with the WISC V offers the comprehensive guidance you need to administer, score, and interpret WISC V profiles for informing diagnoses and making meaningful educational recommendations. This essential resource provides you with cutting-edge expertise on how to interpret the WISC V, which has an expanded test structure, additional subtests, and an array of new composites. Intelligent Testing offers valuable advice from experienced professionals with regard to clinically applying the WISC V in an effort to understand a child's strengths and weaknesses and to create a targeted, appropriate intervention plan. Ultimately, this book equips you with the information you need to identify the best theory-based methods for interpreting each child's profile of test scores within the context of his or her background and behaviors. Intelligent Testing provides a strong theoretical basis for interpreting the WISC V from several vantage points, such as neuropsychological processing theory and the Cattell-Horn-Carroll (CHC) model, yet it permits you to interpret children's profiles using simple, straightforward steps. The most frequently used IQ test in the world, the WISC V (like previous versions of the WISC) plays an integral role in evaluating children for learning and intellectual disabilities, developmental and language delays, and gifted and talented classifications. As such, understanding how to use the latest version of WISC is extremely important when assessing children and adolescents ages 6 to 16 years. * Explore all aspects of both the conventional WISC V and WISC V Digital * Read objective, independent test reviews of the WISC V from independent, highly-respected expert sources * Review 17 clinical case reports that spotlight experiences of children and adolescents referred to psychologists for diverse reasons such as reading problems, specific learning disabilities, ADHD, intellectual giftedness, and autistic spectrum disorders * Learn how a broad-based, multi-faceted approach to interpretation that calls upon several scientific concepts from the fields of cognitive neuroscience, clinical and school neuropsychology, neuropsychological processing, and the CHC model, can benefit children by providing meaningful recommendations to parents, teachers, and often to the children and adolescents themselves * Use the results of WISC V as a helping agent to assist in creating the best intervention plan, rather than allowing test results to dictate placement or labeling Intelligent Testing with the WISC V is an indispensable resource for professionals who work with the WISC V, including school psychologists, clinical psychologists, educational diagnosticians, and more.

This book provides a full guide to creating and running an intensive treatment program for youth with Obsessive Compulsive Disorder (OCD). It offers readers a guidebook on how to administer evidence-based treatments for OCD, including cognitive behavior therapy (CBT), exposure and response prevention (ERP), medication management, parent guidance, and family work, in an intensive format to target moderate to severe OCD over a brief period of time. There is a rapidly growing interest in brief intensive treatment modalities in both clinical and research settings. Intensive treatment for OCD condenses evidence-based interventions into more patient contact hours per week than standard weekly therapy, and is widely supported as an efficient, effective, and desirable treatment option. Intensive treatment can be widely applicable to different patient groups, including those with more severe symptoms for whom weekly therapy is not sufficient, and those who have mild or moderate symptoms but do not have access to evidence-based treatments in their geographic region. Despite broad interest in developing concentrated treatment programs for OCD, practitioners face several challenges when trying to launch and maintain these programs. This book will provide a comprehensive guide covering the topics of import for clinicians, researchers and administrators, across different types of institutions and care settings, who want to build an intensive treatment program into their clinical practice across different types of institutions and care settings.

Item response theory (IRT) has moved beyond the confines of educational measurement into assessment domains such as personality, psychopathology, and patient-reported outcomes. Classic and emerging IRT methods and applications that are revolutionizing psychological measurement, particularly for health assessments used to demonstrate treatment effectiveness, are reviewed in this new volume. World renowned contributors present the latest research and methodologies about these models along with their applications and related challenges. Examples using real data, some from NIH-PROMIS, show how to apply these models in actual research situations. Chapters review fundamental issues of IRT, modern estimation methods, testing assumptions, evaluating fit, item banking, scoring in multidimensional models, and advanced IRT methods. New multidimensional models are provided along with suggestions for deciding among the family of IRT models available. Each chapter provides an introduction, describes state-of-the art research methods, demonstrates an application, and provides a summary. The book addresses the most critical IRT conceptual and statistical issues confronting researchers and advanced students in psychology, education, and medicine today. Although the chapters highlight health outcomes data the issues addressed are relevant to any content domain. The book addresses: IRT models applied to non-educational data especially patient reported outcomes Differences between cognitive and non-cognitive constructs and the challenges these bring to modeling. The application of multidimensional IRT models designed to capture typical performance data. Cutting-edge methods for deriving a single latent dimension from multidimensional data A new model designed for the measurement of constructs that are defined on one end of a continuum such as substance abuse Scoring individuals under different multidimensional IRT models and item banking for patient-reported health outcomes How to evaluate measurement invariance, diagnose problems with response categories, and assess growth and change. Part 1 reviews fundamental topics such as assumption testing, parameter estimation, and the assessment of model and person fit. New, emerging, and classic IRT models including modeling multidimensional data and the use of new IRT models in typical performance measurement contexts are examined in Part 2. Part 3 reviews the major applications of IRT models such as scoring, item banking for patient-reported health outcomes, evaluating measurement invariance, linking scales to a common metric, and measuring growth and change. The book concludes with a look at future IRT applications in health outcomes measurement. The book summarizes the latest advances and critiques foundational topics such a multidimensionality, assessment of fit, handling non-normality, as well as applied topics such as differential item functioning and multidimensional linking. Intended for researchers, advanced students, and practitioners in psychology, education, and medicine interested in applying IRT methods, this book also serves as a text in advanced graduate courses on IRT or measurement. Familiarity with factor analysis, latent variables, IRT, and basic measurement theory is assumed.
