My 16-year-old daughter was diagnosed with schizoaffective disorder six months ago. But now her psychiatrist is saying that he thinks she may also have dissociative identity disorder (DID), also known as multiple personality disorder. Unfortunately, he has no experience diagnosing or treating DID, so he wants us to go to an expert who does. He doesn't know of any such professional, and I have researched high and low, talked to dozens of professionals, gotten referral lists from every organization, etc. -- only to find that there is no DID expert in Arizona. So now we are willing to travel anywhere in the U.S. to find a DID expert who can assess and treat our daughter. Does anyone know of a psychiatrist or psychologist who has extensive experience with DID?
