Objective: To test the reliability and validity of the Adolescent Dissociative Experiences Scale Taxon(A-DES-T) in Chinese adolescents. Methods: Mental health state of 1466 students was assessed at about 3.5 years after they survived in the 5·12 Wenchuan Earthquake, and valid data of 1292 teenagers were obtained. The A-DES-T, Essen Trauma Inventory for Kids and Juvenile(ETI-KJ) and Symptom Checklist(SCL-90) were used for the evaluation. Results: One factor was extracted after the exploratory factor analysis. The results of confirmatory factor analysis supported the one-factor construction(x2/df=4.01, CFI=0.96, NFI=0.94, NNFI=0.94,RMSEA=0.07, SRMR=0.04). The internal consistency coefficient Cronbach's alpha of A-DES-T was 0.84, and the test-retest reliability coefficient was 0.86. A-DES-T scores had a moderate positive significant correlation with 10 factors and global severity index(GSI) of SCL-90(r=0.53~0.68), and participants with different levels of PTSD symptoms scored significantly different on the A-DES-T(F=132.34, P0.001). The more PTSD symptoms the teenagers had, the higher score they got on A-DES-T. Conclusion: A-DES-T showed good reliability and validity in adolescents aged from 11 to 18, who survived the 5·12 Wenchuan earthquake, and could be used in our country.
