Scale Development
Theory and Applications

Fourth Edition


March 2016 | 280 pages | SAGE Publications, Inc
In the Fourth Edition of Scale Development, Robert F. DeVellis demystifies measurement by emphasizing a logical rather than strictly mathematical understanding of concepts. The text supports readers in comprehending newer approaches to measurement, comparing them to classical approaches, and grasping more clearly the relative merits of each. This edition addresses new topics pertinent to modern measurement approaches and includes additional exercises and topics for class discussion.

“This is the foremost text on scale development for both the experienced and novice researcher alike.”

Richard Conti
Kean University

“The Fourth Edition captures the recent development in measurement (e.g., alternatives to Alpha, bifactor model, hierarchical factor model, and available tools in R) by explaining concepts using accessible languages and examples.”

Shuyan Sun
University of Maryland

“The Fourth Edition of Scale Development incorporates practical examples and exercises to aid in student learning and understanding the fundamentals of measurement. The text continues to be a go-to resource for scholars and students alike.” 

Stephen W. Dittmore

PRAISE FOR THE PREVIOUS EDITION

“The key strength of this text is its ability to present the basic and necessary background on scale construction and measurement for the subsequent material, either in the context of the same first-year graduate course or in future courses during a masters and PhD program.”

René Bautista
University of Nebraska – Lincoln

“This book does an excellent job in explaining complicated topics in test construction at a level that students can understand. The use of specific examples that demonstrate key points is very effective.”

Jonathan Feldman, Yeshiva University

Great organization of the flow in the text!
