Q: Inter-subject Reliability

Hi all

Summary: Can r be used as a parametric variable?

I have a bit of a problem in my research and I was wondering if any
could help.

The problem is:
12 Subjects rated 20 items on 2 different scales. I believe that on one
of these scales subjects will agree in general on what ratings to give
and on the other there will be more variability between subjects'

To get a measure of subject agreement I have correlated each subject's
scores with each other subject's score on that scale. This give me two
set of r values one of 0.09 and one of 0.01. I want to know if a t test
on these r values would be a legitimate test to conduct to see if there
is significantly greater agreement between subjects and one scale than
on the other. If so does this test have a particular name?

If the procedure is not appropriate then can anyone suggest a test that
can compare inter subject reliability.

I would prefer if replies are e-mailed and I will post a summary of
replies if I receive them
