In this April 2010 photo provided by the University of Pennsylvania, Edna Foa, from the Perelman School of Medicine at the University of Pennsylvania, speaks to a patient at her office in Philadelphia. Foa developed a two-part treatment in which patients sexually abused patients tell their traumatic stories over and over again. The results are the first evidence that the same kind of "exposure" therapy that helps combat veterans haunted by flashbacks and nightmares also works for traumatized sexually abused teens with similar symptoms, the study authors and other experts said. The new study was published on Tuesday, Dec. 24, 2013, in the Journal of the American Medical Association.
