Prevalence of posttraumatic stress disorder in women with breast cancer.

This study investigated whether diagnosis and treatment of breast cancer produced posttraumatic stress disorder (PTSD) in adult women. One hundred sixty women with early stage node-negative breast cancer completed self-report questionnaires and underwent a full diagnostic assessment (Structured Clinical Interview for DSM-III-R). PTSD symptoms were common; however, only 3% of the women interviewed met stringent criteria for cancer-related PTSD in the 4-12 months following the completion of their medical treatment. Thus, breast cancer produced considerable distress, but low rates of PTSD, and may not fit well as a Criterion A stressor event for PTSD. Caution is urged for an assumption of a PTSD diagnosis based on self-reported symptoms.
