Abstract

The current study investigated the factor structure of posttraumatic stress symptoms assessed by the Impact Event Scale-Revised (IES-R) in a large sample of individuals from China who recently experienced a destructive earthquake. The results of the confirmatory factor analysis indicated that a four-factor structure (intrusion, avoidance-numbing, hyperarousal, and sleep disturbance) emerged as the model best fit in total sample, female and male subsamples, respectively. Moreover, multiple-group confirmatory factor analysis further demonstrated that the four-factor model was quite stable across sex. Implication and limitations for the results are discussed.
