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. The rates of lifetime PTSD observed for the breast patients 26 and witnesses 24 are concordant with the rates of PTSD from other traumatic events. However, the percentages of lifetime PTSD cases that are current among the patients 35 and witnesses 33 are lower than seen with other traumatic events. These data suggest that breast cancer can lead to PTSD in patients and witnesses, but these PTSD patients are more likely to recover from their PTSD than other traumatized persons. Preliminary statistical analyses support the hypothesis that physiologic responses during personal imagery of breast-cancer-related experiences are greater in breast cancer witnesses with PTSD than in breast cancer witnesses who never had PTSD. A one-year no-cost extension has been granted for further analyses of the data and the preparation of publications.
