Objective     To evaluate the reliability and validity of the Chinese version of posttraumatic growth inventory (PTGI) in Marine Corps. Methods     A total of 651 marines were participated in the evaluation using the Chinese versions of PTGI

Connor-Davidson resilience scale (CD-RISC)

trait anxiety inventory (TAI)

and general self-efficacy scale (GSES). They all had experienced highly intensive military training and stressful events. The samples were then divided by number of odd and even. Sample one (n=326) was examined with the exploratory factor analysis (EFA)

and sample two (n=325) was examined with confirmatory factor analysis (CFA). Results      ① 17 questions were remained in the EFA. The result showed 3 factors with eigenvalue greater than 1

accounting for 54.00% of the total variance. The factors were personal strength

social relationship

and acceptance. ② CFA data validated the wellfit of the 3-factor model (Chi-square/df=2.793

CFI=0.909

TLI=0.893

RMSEA=0.074). ③ The internal consistency of the 3-factor model of PTGI was reliable (α=0.910). ④ Total score of revised PTGI was positively correlated with resilience and general self-efficacy (r=0.560

r=0.487

P0.01)

and negatively correlated with trait anxiety (r=-0436

P0.01)

which suggested that the revised version of PTGI had good criterion validity. Conclusion     The reliability and validity of the revised Chinese version of PTGI meets the criteria of psychometry. It can be used for assessment of trauma-related research in Chinese marine corps.
