The population discrepancy of coefficient a! from the composite reliability coefficient for fixed congeneric measures with correlated errors is studied and expressed in terms of parameters of the measures. Use of structural equation modeling methodology is recommended for identifying cases in which this discrepancy can be large. The findings are demonstrated across several empirical conditions in a scale construction context.
