Paris Hilton's psychiatrist declared that the heiress is "distraught and traumatized" and "fears incarceration" after a judge sentenced her to 45 days in jail.
Dr. Charles Sophy gave those findings in a Los Angeles Superior Court document filed Monday in an ongoing $10 million slander and libel suit against Hilton by actress Zeta Graff.
Hilton is facing an order to testify in the civil trial beginning May 21, but the psychiatrist argues that "given (Hilton's) current psychological, and emotional state ... (she's) not capable of any meaningful participation in a trial."
Sophy says Hilton, 26, needs to recover from the outcome of the jail sentence
. Hilton was given jail time for violating her probation for driving with a suspended license.
The documents, filed by Hilton's lawyers in the slander suit, show that Dr. Sophy has been treating Hilton for the past eight months, and had met with her several times since her probation violation hearing.
"She is emotionally distraught and traumatized as a consequence of the findings at the May 4 hearing, the jail sentence imposed upon her by the judge, and her fear of incarceration," Sophy wrote.
Graff has accused Hilton of fabricating lies against her which appeared in a July 2005 edition of the New York Post
. Graff alleges that she was falsely described as stalking Hilton and her ex, Paris Latsis (whom Graff had dated).
Hilton's rep declined to comment on the psychiatric report.
