Abstract The Posttraumatic Stress Disorder Interview (PTSD‐I; Watson, C. G., Juba, M., Manifold, V., Kucala, T., & Anderson, E. D., 1991) was adapted into a self‐report questionnaire, the Posttraumatic Stress Disorder Questionnaire (PTSD‐Q), which was validated against the Structured Clinical Interview for DSM‐IV (SCID‐IV) PTSD module (First, Spitzer, Gibbon, & Williams, 1995), using a sample of 76 college‐age women who were not seeking help for psychological problems. The women completed the PTSD‐Q and were later interviewed with the SCID‐IV PTSD module. Use of a Receiver Operating Characteristic curve analysis indicated that a cut point of 60 on the PTSD‐Q provided the optimal diagnostic efficiency relative to the SCID‐IV diagnosis. Using a cut point of 60 on the PTSD‐Q resulted in a sensitivity of .81 and a specificity of .82, relative to SCID‐IV diagnoses. The PTSD‐Q may be a useful screening measure to identify individuals who are not seeking help but who have PTSD.
