“Dr. Dimitrov has constructed a masterpiece—a classic resource that should adorn the shelf of every counseling researcher and graduate student serious about the construction and validation of high quality research instruments. —Bradley T. Erford, PhD Loyola University Maryland Past President, American Counseling Association “This book offers a comprehensive treatment of the statistical models and methods needed to properly examine the psychometric properties of assessment scale data. It is certain to become a definitive reference for both novice and experienced researchers alike.” —George A. Marcoulides, PhD University of California, Riverside This instructive book presents statistical methods and procedures for the validation of assessment scale data used in counseling, psychology, education, and related fields. In Part I, measurement scales, reliability, and the unified construct-based model of validity are discussed, along with key steps in instrument development. Part II describes factor analyses in construct validation, including exploratory factor analysis, confirmatory factor analysis, and models of multitrait-multimethod data analysis. Traditional and Rasch-based analyses of binary and rating scales are examined in Part III. Dr. Dimitrov offers students, researchers, and clinicians step-by-step guidance on contemporary methodological principles, statistical methods, and psychometric procedures that are useful in the development or validation of assessment scale data. Numerous examples, tables, and figures provided throughout the text illustrate the underlying principles of measurement in a clear and concise manner for practical application. *Requests for digital versions from ACA can be found on www.wiley.com. *To purchase print copies, please visit the ACA website here. *Reproduction requests for material from books published by ACA should be directed to [email protected]

The purpose of this book is to present statistical methods and procedures used in contemporary approaches to validation of targeted construts through the use of asseement scales (test, inventories, questionnaires, surveys). Validity is a property of data and inference made from data rather than a property of scales. The book in divides in three parts : I. Scales, Reliability and Validity. II Factor Analysis in Construct Validation. III. Psychometric Scale Analysis.

Designed to help students learn how to assess clients, conduct treatment planning, and evaluate client outcomes, this practical book addresses specific CACREP competencies. Incorporating case studies and examples, authors Joshua C. Watson and Brandé Flamez provide foundational knowledge for sound formal and informal assessments, cover ethical and legal considerations in assessment, describe basic statistical concepts, highlight the domains in which assessments are commonly used (intelligence, aptitude, achievement, personality, career, etc.), and provide strategies for integrating assessment data when working with clients. Counseling Assessment and Evaluation is part of the SAGE Counseling and Professional Identity Series, which targets specific competencies identified by CACREP (Council for Accreditation of Counseling and Related Programs).

Using a conceptual, non-mathematical approach, the updated Third Edition provides full coverage of the wide range of multivariate topics that graduate students across the social and behavioral sciences encounter. Authors Lawrence S. Meyers, Glenn Gamst, and A. J. Guarino integrate innovative multicultural topics in examples throughout the book, which include both conceptual and practical coverage of: statistical techniques of data screening; multiple regression; multilevel modeling; exploratory factor analysis; discriminant analysis; structural equation modeling; structural equation modeling invariance; survival analysis; multidimensional scaling; and cluster analysis.

"This book will examine the various digital technologies such as the Internet of Things (IoT), Artificial Intelligence (AI), and Blockchain and their applications in the service sector to promote economic growth, create new job opportunities, and improve access to essential services such as education, healthcare, and financial services"--

In Practicing Forgiveness, the author reviews the contextual and cultural aspects of forgiveness with stories, humor, clinical examples, research, and empirical findings while examining the influence of environment and religion. The content is presented in such a way so as to serve as a resource to both professional mental health providers (who can benefit from the theoretical and empirical underpinnings of working with clients through the forgivenessprocess) and lay readers (who can benefit from the processing and self-help components of the book).
