This article demonstrates that when using Department of Veterans Affairs (VA) administrative data to compile posttraumatic stress disorder (PTSD) samples, researchers should locate participants with at least two PTSD diagnoses to increase the likelihood that selected participants do have PTSD. This study also provides information about the actual composition of PTSD samples when they are selected by using at least two diagnoses. Researchers can use this information when selecting samples for research studies, which will lead to more accurate inferences being made from VA PTSD research studies and, ultimately, more effective interventions for PTSD.
