The objectives are a. to evaluate the incidence of post-traumatic stress disorder PTSD in breast cancer patients and witnesses i.e., significant others, and b. to validate interview-based diagnoses by measuring physiologic responses during script-driven imagery of patients and witnesses personal experiences with breast cancer. To date, of 58 breast cancer patients studied, 4 7 met DSM-IV criteria for current PTSD 11 19 for past PTSD and 43 74 patients for neither. In the laboratory, 1 33 of 3 current PTSD patients, 1 10 of 10 past PTSD patients, and 5 19 of 27 never PTSD patients were physiologic responders. Similarly low rates of the PTSD diagnosis and of physiologic responding have been found in 41 witnesses studied. These data call into question being diagnosed with a life-threatening illness DSM-IV, p. 424 as a source of physiologically valid PTSD.
