Commentary on Coefficient Alpha: A Cautionary Tale
Green, Samuel B.; Yang, Yanyun
Psychometrika, v74 n1 p121-135 Mar 2009
The general use of coefficient alpha to assess reliability should be discouraged on a number of grounds. The assumptions underlying coefficient alpha are unlikely to hold in practice, and violation of these assumptions can result in nontrivial negative or positive bias. Structural equation modeling was discussed as an informative process both to assess the assumptions underlying coefficient alpha and to estimate reliability.
