    Test Development and Validation

    Test Development and Validation by Gary Skaggs summarizes the latest test theories, frameworks for test development and validation, and guidance for developing tests in straightforward language in one core text.Students looking for clear, concise explanations of measurement, validity, and test development within a real-world context and with numerous examples will find this book to be an excellent learning resource.Author Gary Skaggs takes years of experience teaching test development to graduate students across social and behavioral sciences and consulting on a wide variety of government and institutional research projects to offer students a thorough, jargon-free, and highly applied book to help propel their own research and careers. Part I of the book, The Big Picture, sets the stage for test development, placing it within the larger context and history of measurement, emphasizing measurement concepts and their evolution over time.Part II, Test Development, covers the technical details of instrument and test development in logical order.Validation, Part III, links the conceptual bases provided in Part I with the technical process provided in Part II to conclude the book.For those students wanting to go further, software suggestions are referenced in the technical chapters, while Further Reading sections offer the original sources for more details.Exercises and Activities at the end of each chapter provide students a variety of ways to apply their knowledge, from conceptual questions to brief project ideas to data analysis problems.

  • Clinical Prediction Models : A Practical Approach to Development, Validation, and Updating
    Clinical Prediction Models : A Practical Approach to Development, Validation, and Updating

    The second edition of this volume provides insight and practical illustrations on how modern statistical concepts and regression methods can be applied in medical prediction problems, including diagnostic and prognostic outcomes.Many advances have been made in statistical approaches towards outcome prediction, but a sensible strategy is needed for model development, validation, and updating, such that prediction models can better support medical practice. There is an increasing need for personalized evidence-based medicine that uses an individualized approach to medical decision-making. In this Big Data era, there is expanded access to large volumes of routinely collected data and an increased number of applications for prediction models, such as targeted early detection of disease and individualized approaches to diagnostic testing and treatment. Clinical Prediction Models presents a practical checklist that needs to be considered for development of avalid prediction model.Steps include preliminary considerations such as dealing with missing values; coding of predictors; selection of main effects and interactions for a multivariable model; estimation of model parameters with shrinkage methods and incorporation of external data; evaluation of performance and usefulness; internal validation; and presentation formatting.The text also addresses common issues that make prediction models suboptimal, such as small sample sizes, exaggerated claims, and poor generalizability.The text is primarily intended for clinical epidemiologists and biostatisticians.Including many case studies and publicly available R code and data sets, the book is also appropriate as a textbook for a graduate course on predictive modeling in diagnosis and prognosis. While practical in nature, the book also provides a philosophical perspective on data analysis in medicine that goes beyond predictive modeling.Updates to this new and expanded edition include:• A discussion of Big Data and its implications for the design of prediction models• Machine learning issues• More simulations with missing ‘y’ values• Extended discussion on between-cohort heterogeneity• Description of ShinyApp• Updated LASSO illustration• New case studies

  • Diagnostic Writing Assessment : The Development and Validation of a Rating Scale
    Diagnostic Writing Assessment : The Development and Validation of a Rating Scale

    The diagnostic assessment of writing is an important aspect of language testing which has often been neclected in the literature.However, it is an area which poses special challenges to practioners both in the classroom and in large-scale testing situations.This book presents a study which set out to develop and validate a rating scale specifically designed for the diagnostic assessment of writing in an academic English setting.The scale was developed by analysing a large number of writing performances produced by both native speakers of English and learners of English as an additional language.The rating scale was then validated using both quantitative and qualitative methods.The study showed that a detailed data-based rating scale is more valid and more useful for diagnostic purposes than the more commonly used impressionistic rating scale.

  • Chasing Masculinity : Men, Validation, and Infidelity
    Chasing Masculinity : Men, Validation, and Infidelity

    This book analyzes men's experiences and perceptions regarding their participation in infidelity and offers a glimpse into the inner workings of their most intimate relationships, as well as the ways men negotiate marriages that fall short of their expectations. Using a sample collected from the online dating service Ashley Madison, this book finds that contrary to gendered social scripts, the men in this study described motivations for outside partnerships that were not rooted in the desire for sexual pleasure or variety.Rather, men described those relationships as an outlet to soothe their bruised egos, receive attention and validation from a romantic partner, and to fight their feelings of emasculation.These infidelities thus provide support and praise, and aid in the processing of complex emotions. This in-depth analysis provides a unique insight into men's experiences of sexuality and masculinity, and will be of keen interest to those seeking to understand male infidelity from a sociological perspective, across gender studies, psychology, counselling, and beyond.
