We know that the majority of people who are dx'd with did REPORT that they have trauma. In the majority of cases there isn't independent verification of that, however.

Which is just to say - that we don't know that trauma is the cause in the majority of cases.

I know that one of the main theories of DID is known as the 'post-traumatic model'.

But if you go around saying that you MUST have been traumatised in order to have DID or to 'really have' DID well then...

The things people will say to try and make sense to themselves...
