系数a!的总体差异从复合可靠度系数出发，研究了具有相关误差的固定同类测度的复合可靠度系数，并用测度的参数表示。建议使用结构方程建模方法来确定这种差异可能很大的情况。研究结果证明了在规模建设背景下的几个经验条件。
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.
