The main aim of this study is to investigate the reliability and validity of the Chinese version of SPAN. Posttraumatic stress disorder is an anxiety disorder, currently defined by the coexistence of three clusters of symptoms (re-experiencing, avoidance, and hyperarousal), persisting for at least one month, in survivors of a traumatic event. The Davidson Trauma Scale (DTS) is a validated 17-item self-rating scale used to screen for posttraumatic stress disorder in epidemiological and clinical studies. A four-item scale, the SPAN (namely for its top four items: startle, physiological upset, anger, and numbness), was derived from DTS. The reliability and validity of the Chinese version SPAN (SPAN-C) were tested on a group of 182 subjects of 921 earthquake victims and rescuers. Among them, 73 subjects met the DSM-IV diagnostic criteria of posttraumatic stress disorder. The SPAN-C demonstrated good internal consistency (Cronbach’s a=0.77). Significant correlation between DTS-C and SPAN-C was found (g=0.93, p＜0.001). The diagnostic accuracy was 78% at a SPAN-C score of 5. This study revealed that the Chinese version SPAN had good reliability and validity. The study suggests that the Chinese version of the SPAN-C may be a suitable tool in screening for patients with posttraumatic stress disorder.
