Developing a C hinese PTSD I nventory ( CPI ) based on interviews with earthquake victims in S ichuan

Although some of the self‐report scales for posttraumatic stress disorder ( PTSD ) are available in C hinese and are currently in use in C hina, cultural limitations exist. An indigenous C hinese PTSD self‐rating scale—the C hinese PTSD I nventory ( CPI )—has been developed. The item generation of the CPI was based on interviews of S ichuan earthquake victims. Exploratory factor analysis was conducted on a sample of 313 earthquake victims, acquiring five factors with 27 items: Intrusion, Avoidance, Hyperarousal, Dysphoria, and Somatization. Another sample of 227 debris‐flow victims was administered the 27‐item CPI . It demonstrated high internal consistency and test‐retest reliability, and the result of confirmatory factor analysis indicated a good fit for the five‐factor model.
