In a series of SEM Journal articles, Raykov demonstrated that the composite reliability for a set of continuous items is explainable as: var(true) / [var(true) + var(residual)] within a CFA model where var(true) is equal to the sum across items of the variance explainable for each item and var(residual) is the sum of the residual error variances.
