Abstract:
Sijtsma and Pfadt (Psychometrika, 2021) provide a wide-ranging defense for the use of coefficient alpha. Alpha is practical and useful when its limitations are acceptable. This paper discusses several methodologies for reliability, some new here, that go beyond alpha and were not emphasized by Sijtsma and Pfadt. Bentler's (Psychometrika 33:335-345, 1968. https://doi.org/10.1007/BF02289328 ) combined factor analysis (FA) and classical test theory (CTT) model. FACTT provides a key conceptual foundation.
