TLDR
In this paper, the authors clarified ambiguities in a recent paper on the computation and statistics of the greatest lower bound, and showed that the computation of the lower bound is computationally efficient.Abstract:

Best Alternatives to Cronbach's Alpha Reliability in Realistic Conditions: Congeneric and Asymmetrical Measurements.
TL;DR: Using Monte Carlo simulation, the performance of Cronbach's alpha reliability coefficients under a one-dimensional model is evaluated in terms of skewness and no tau-equivalence and shows that omega coefficient is always better choice than alpha and in the presence of skew items is preferable to use omega and glb coefficients even in small samples.
Journal ArticleDOI
Internal consistency of tests: Analyses old and new
TL;DR: In this article, the authors proposed a consistent estimate of the greatest defensible internal consistency coefficient by factoring item covariances, which is based on Guttman's "immediate retest reliability".
Book ChapterDOI
Multivariate Reliability Theory
TL;DR: Reliability is one of the most basic concepts of science and a prerequisite for scientific work as discussed by the authors. But without reliable measurements, not even scientific empirical psychology could exist, let alone multivariate psychology or multivariate experimental psychology.

On robustness of the normal-theory based asymptotic distributions of three reliability coefficient estimates
Ke-Hai Yuan,Peter M. Bentler +1 more
TL;DR: In this article, the asymptotic distributions of three reliability coefficient estimates (sample coefficient alpha, the reliability estimate of a composite score following a factor analysis, and the estimate of the maximal reliability of a linear combination of item scores) were studied.

Measurement errors in multivariate measurement scales
Lauri Tarkkonen,Kimmo Vehkalahti +1 more
TL;DR: In this article, a general measurement framework for analyzing the effects of measurement errors in multivariate measurement scales is presented. But it is more appropriate than the classical procedures, especially in the context of multivariate analyses.

Inequalities among lower bounds to reliability: With applications to test construction and factor analysis
TL;DR: In this article, a chain of lower-bound inequalities leading to the greatest lower bound to reliability is established for the internal consistency of a composite of unit-weighted components, including the maximum split-half coefficient, the lowest coefficient consistent with nonimaginary common factors, and the lowest coefficients consistent with nonsmooth common and unique factors.

Computational aspects of the greatest lower bound to the reliability and constrained minimum trace factor-analysis
TL;DR: In this paper, the convergence properties of several algorithms for computing the greatest lower bound to reliability or the constrained minimum trace communality solution in factor analysis have been examined, and it is shown that a slightly modified version of one method suggested by Bentler and Woodward can safely be applied to any set of data.
