Coefficient α as a Measure of Test Score Reliability: Review of 3 Popular Misconceptions.

Osvaldo F Morera1, Sonya M Stokes1.   

Abstract

We discuss 3 popular misconceptions about Cronbach α or coefficient α, traditionally used in public health and the behavioral sciences as an index of test score reliability. We also review several other indices of test score reliability. We encourage researchers to thoughtfully consider the nature of their data and the options when choosing an index of reliability, and to clearly communicate this choice and its implications to their audiences.
