“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]

Counseling Assessment and Evaluation
Designed to help students learn how to assess clients, conduct treatment planning, and evaluate client outcomes, Counseling Assessment and Evaluation 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. “Watson and Flamez have captured the essence of the assessment process in their new book. Through rich case illustrations and the authors’ deep knowledge of the subject, readers are provided the most current trends and reflections on the assessment process.” —Bill McHenry, Texas A&M University–Texarkana “The text is very straightforward and easy to read. It encourages students to apply what they are learning through case illustrations and guided practice exercises.” —Wendy Killam, Stephen F. Austin State University “Watson and Flamez provide the reader with an engaging discussion of the fundamentals of counseling assessment and evaluation. ?—Mark W. Dewalt, Winthrop University “The case illustrations and the practice exercises are exceptional and go a long way toward making the material accessible. Case examples in the body of the text are also well done.” —Patricia Andersen, Midwestern State University
