The SPAN is a four-item self-report screen derived from the Davidson Trauma Scale. Its name is an acronym for the four symptoms assessed (startle, physically upset by reminders, anger, and numbness). The four items that make up the SPAN are the items from the DTS that best distinguished a sample of patients with PTSD from a sample of patients without PTSD.
Respondents are asked to rate items on a five-point scale (ranging from 0 = "Not at all distressing" to 4 = "Extremely distressing") to indicate how distressing each of the symptoms-items has been during the past week. A total score of five indicates a positive screen. Those screening positive should then be assessed with a structured interview for PTSD.
Sample items cannot be reproduced.
