My daughter had hers, the doctors want to make sure the patient is a good canidate. Thre are certain personalities that are not good canidates. Those that put all the apples in the basket to be the perfect answer to their pain to reslove...from what psych told daughter.

IT is a two part, that 500 question MMPI, and then interview.
It was really nothing....
I would be relaxed, open and and don;t worry.
