"But the biggest short-coming in Rieber's attempt to discredit Schreiber and Wilbur is in what he leaves out of his discussion. In a couple of brief paragraphs, he cites Herbert Spiegel as his primary authority for challenging the diagnosis of MPD/DID, implying that Spiegel diagnosed Sybil as a hysteric and that he found no evidence of Sybil having been sexually abused by her mother or father. I wanted to know so much more of what Spiegel, Rieber's long-time colleague, thought of the case: How did he account for the lost time and other dissociative phenomena? What was his understanding of how the alters came to manifest themselves during the sessions with Wilbur? To have a detailed discussion of this case by an expert such as Herbert Spiegel would have added so much to our understanding of the MPD/DID phenomenon. Instead, I was left with more questions than answers."
In reply to the statement that MPD is a "cry for attention" is totally unbacked by any scientific evidence. The preponderance of scientific evidence, including its inclusion in the DSM, shows it to be a strong phenomenon.
DID has been found to meet all of the guidelines for inclusion in the DSM and is supported by taxometric research and research has established DID as a valid diagnosis.

Coons PM, Bowman ES, Milstein V. Multiple personality disorder. A clinical investigation of 50 cases. J Nerv Ment Dis. 1988 Sep;176(9):519-27. "50 consecutive patients with DSM-III multiple personality disorder were assessed using clinical history, psychiatric interview, neurological examination, electroencephalogram, MMPI, intelligence testing, and a variety of psychiatric rating scales. Results revealed that patients with multiple personality are usually women who present with depression, suicide attempts, repeated amnesic episodes, and a history of childhood trauma, particularly sexual abuse....These data suggest that the etiology of multiple personality is strongly related to childhood trauma rather than to an underlying electrophysiological dysfunction."

In reply to phone calls made to the FMSF by accused parents and DID, there is no real evidence that the accused parents are telling the truth.
The DSM states that the reports of patients suffering from DID are "often confirmed by objective evidence," and the DSM notes that the abusers in those situations may be inclined to "deny or distort” these acts.
