Summated Rating Scale Construction de Paul E. Spector

Summated Rating Scale Construction

Autor Paul E. Spector
en Limba Engleză Paperback – 26 noi 1991
The goal for any social scientist doing a survey is to develop a rating on some attitude, value or opinion - a summated rating scale. Aimed at helping researchers construct more effective scales, Spector shows how to determine the number of items necessary, the appropriate amount of response categories and the most productive wording of items, how to sort good items from bad (including item-remainder coefficients and Cronbach's alpha) and how to validate a scale, including dimensional validity from factor analysis. Written in a user-friendly manner, the book concludes with a step-by-step account of how to develop a summated rating scale based on classical test theory.

Recenzii

"The steps of scale development are clearly explained, with brief rationales of the methods involved...Having read the book, almost anyone with a basic social science education could go through the practical motions of developing a scale...says in general terms that theory is important and goes on to provide hints on how to generate a pool of items. The hints are empirically sound and useful.."
