One way to address your research question, albeit with a different analysis,
is to conduct a mutli-group Stuctural Equation Model, with AMOS or your
favorite SEM package. Test a model in which the items load on the relevant
scales. Test the model separately for males and females. Constrain the
item loadings to be equal in both samples and see whether this results in a
significantly poorer fit. If there is a poorer fit, see which item(s)
differ substantially between samples and by how much.
If you have multiple scales, you can also examine whether the scale
intercorrelations are the same for both males and females - a separate but
potentially interesting question.

I am interested in determining if the internal consistency of a battery of
items differs for women and men. Thus, I am interested in determining if the
two Chronbach alphas are significantly different. How would I do this?
