DeVellis, R. F. (2003). Scale Development Theory and Applications.
Second Edition. London: SagePublications.


This book presents complex concepts in a way that helps students to understand the logic underlying the creation, use, and evaluation of measurement instruments and to develop a more intuitive feel for how scales work. Robert DeVellis demystifies measurement by relating it to familiar experiences and by emphasizing a conceptual rather than a strictly mathematical understanding. Students’ attention is drawn to important concepts that are foundational for subsequent topics, with opportunities provided to test understanding through chapter summaries and exercises.

Scale Development is widely adopted on graduate courses in departments of psychology, public health, nursing, education, and marketing, and has proved invaluable to applied researchers across the social sciences.
