Summated Rating Scale Construction: An Introduction Paul E. Spector’s is an English-language textbook that provides insight into the construction of summated rating scales. This book is suitable for students and researchers in higher education who are involved in the social sciences and statistics.
The book covers the practical aspects of rating scale construction, such as determining the number of items required, the optimal response categories, and formulating effective questions. In addition, Spector discusses methods for distinguishing good items and conducting scale validation, including the use of item-remainder correlations, Cronbach’s alpha, and factor analysis for dimensional validity.
With clear explanations and a step-by-step approach, this title supports the development of reliable summated ratings based on classical test theory.
In terms of content, it aligns with topics such as social research, statistics, and scale construction.
