Hi, You can take a look at these articles:
Hakstian & Whalen (1976, Psychometrika) A K-Sample significance test for independent alpha coefficients. Feldt, Woodruff, & Salih (1987, Applied Psychological Measurement) Statistical inference for coefficient alpha. L.S. Feldt and colleagues published several other articles on the topic. You may find one or more of them relevant to your study. Hope this helps.
