Have you been formally diagnosed with a dissociative disorder?

If so, what instrument was used as a diagnostic tool?

We have been diagnosed with DID a long time ago. The assessment tool was the DDIS - the Dissociative disorders Interview Schedule.
The new psychologist gave us the DES a month or two ago. We are having another diagnostic assessment done in a few weeks.The next assessment is being done by a psychiatrist that is flying in from a different city. I don't know what diagnostic tool will be used. We are nervous because we don't know her.
