The presence of a posttraumatic stress disorder (PTSD) diagnosis in women (n = 82)
diagnosed with Stage 0-IIIA breast cancer was assessed 6 to 72 months after cancer
therapy. The PTSD Checklist-Civilian Version (PCL-C) and the PTSD module for the Structured
Clinical Interview for DSM-IV, Nonpatient Version, PTSD module (SCID-NP-PTSD) were
administered in a telephone interview. SCID-NP-PTSD results indicated prevalence rates
of 6% and 4% for current and lifetime PTSD, respectively. Use of the recommended cutoff
score of 50 on the PCL-C to determine diagnosis of current cancer-related PTSD resulted
in a sensitivity of .60 and a specificity of .99 with 2 false-negative diagnoses.
In conclusion, PTSD can be precipitated by diagnosis and treatment of breast cancer,
and the PCL-C can be a cost-effective screening tool for this disorder.
