In accordance with then-current modes of thought on the disorder, Thigpen reported that Sizemore had developed multiple personalities as a result of her witnessing a horrifying accidental death and two serious non-fatal accidents within three months as a small child. By Sizemore's own report, these incidents triggered the evidencing of selves which were already present. "Despite authorities' claims to the contrary, my former alters were not fragments of my birth personality. They were entities, whole in their own rights, who coexisted with my birth personality before I was born. They were not me, but they remain intrinsically related to what it means to be me."[1]

While The Three Faces of Eve was written by Thigpen and Cleckley with limited input from Sizemore, her later books I'm Eve and A Mind Of My Own fill in details. Much earlier, in 1958, she had written Strangers in My Body: The Final Face of Eve, using the pseudonym Evelyn Lancaster. According to psychiatrists who worked with her after she moved from South Carolina, Sizemore did not experience three selves, but approximately 20. The doctors reported that her selves presented in groups of three at a time.[2]

Sizemore reports feeling exploited and objectified by the media blitz surrounding the book and film. Upon discovering in 1988 that her legal rights to her own life story had been signed away to 20th Century Fox by Thigpen, Sizemore went to Manhattan's Federal District Court to contest the contract, and won.

Sizemore was the inspiration for the song Christine and its B-Side "Eve White/Eve Black" by the English rock band Siouxsie and the Banshees.

The 1952-1989 papers of Chris Costner Sizemore have been acquired by Duke University Library. An overview of the collection and a summary of Ms. Sizemore's story are included on its website. Sizemore was interviewed on the BBC News channel series Hard Talk on March 25, 2009.[8]"
