A Test of the Hypothesis that Cronbach's Alpha Reliability Coefficient Is the Same for Two Tests Administered to the Same Sample.
Peer reviewed Peer reviewed
Feldt, Leonard S. – Psychometrika, 1980
Procedures are developed for testing the hypothesis that Cronbach's alpha reliability coefficient is equal for two tests given to the same subjects. (Author/JKS)

A K-Sample Significance Test for Independent Alpha Coefficients
Peer reviewed Peer reviewed
Hakstian, A. Ralph; Whalen, Thomas E. – Psychometrika, 1976
Details of a reasonably precise normalization technique for coefficient alpha are outlined, along with methods for estimating the variance of the normalized statistic. These procedures lead to the K-sample significance test. (RC)
