I administered surveys containing likert-type questions before and after a treatment. Which statistical measuring can I use to determine if individuals changed their attitudes from pre to post? I am fairly certain that it is not proper to use a t-test.

Thanks

use a repeated measures t-test (set up the data file so that each person's pre and post answers are 2 variables on the same line--in the same case).
