Cronbach alpha

[drfg2008]

Can you compare two different cronbach alpha values with a chi-square distribution (or at all)?

Example: testconstruct 1 has C1= 0,75, testconstruct 2 has C2 = 0,67

The question is if the difference of C2 and C1 is statistically significant (without knowing the sample-size)
