Sample Size Requirements for Testing and Estimating Coefficient Alpha.
Bonett, Douglas G.
Journal of Educational and Behavioral Statistics, v27 n4 p335-40 Win 2002
Derived an approximate test and confidence interval for coefficient alpha and used the approximate test and confidence interval to derive closed-form sample size formulas that can be used to determine the sample size needed to test coefficient alpha with desired power or to test coefficient alpha with desired precision.
