Scale Development: Theory and Applications

Image
The book Scale Development Theory and Applications by Robert Devellis provides a strong overview of the creation and development of survey scales for applied social research. He uses simple language with illustrations to make the complex statistical process as easy to understand as possible. It will help researchers develop surveys instruments that do not confound variables and create improper results. One of the more difficult things that researchers face is developing their own survey instrument. Certainly, a person can build a list of questions but these questions may confound variables making the results useless. When possible it is almost always better to use preexisting validated surveys that do not require much work. Unfortunately, for a large percentage of unique problems one has to start the daunting task of building their own. The book will move through an introductory background of measurement research and how important it has been throughout history. Duncan states i
