Abstract
The restrictive assumption of classical parallelism for the Spearman-Brown formulas makes them obsolete when the two-part alpha and coefficient alpha formulas can be used. The alpha coefficients require the less restrictive assumption of essential tau-equivalence. Even small reliability differences produced by the Spearman-Brown and alpha coefficient formulas on the same data can result in large applied differences.
