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...

Written at an accessible level, Scale Development, Second Edition guides the reader toward the identification of the latent variable, the generation of an item pool, the format for measurement and the optimization of the scale length. Using exercises to illustrate the concepts,...

Measurement -- the way researchers quantify the observations they have made about people, objects, events, or even processes -- is a fundamental activity of science. One of the main frustrations researchers have experienced in measurement is the lack of an appropriate instrument...
