Summated Rating Scale Construction is a step-by-step guide to creating multiple item scales that can be used to assess people’s attitudes, behavior, beliefs, motives, perceptions, values and many more things. It begins by explaining what these scales are and why they offer advantages over using single items. The process of developing a scale is explained, including defining the construct you wish to measure, designing the scale, writing items, collecting test data, and conducting analyses to refine the scales. Determining reliability and strategies for collecting validation data are covered. How to us item-analysis and factor analysis for scale development is discussed. This book is volume 82 in the Sage Quantitative Applications in the Social Science series, commonly referred to as the “little green books”. I wrote this one and Research Designs.
