Abstract: Objective: To translate the Secondary Posttraumatic Growth Inventory (SPTGI) into Chinese and test its reliability and validity among clinical nurses, providing a reliable tool for assessing secondary posttraumatic growth in nurses in China. Methods: The SPTGI was adapted to Chinese through forward translation, back translation, cultural adaptation, and pre-testing, according to the Brislin translation model. A total of 543 clinical nurses from a tertiary grade A hospital in Anhui province were investigated using convenience sampling method from November 2023 to August 2024. Item analysis, exploratory factor analysis, confirmatory factor analysis, and reliability testing were conducted. Results: The Chinese version of the SPTGI included four dimensions with 12 items. The content validity index for the scale was 0.833, with item-specific content validity indices ranging from 0.750-1.000. Exploratory factor analysis revealed a four-factor structure, explaining 77.490% of the total variance. Confirmatory factor analysis showed a good model fit. The Cronbach’s α coefficient for the entire scale was 0.899, and the Cronbach’s α coefficient for each dimensions was 0.793-0.881. Test-retest reliability for the total scale was 0.883. Conclusion: The Chinese version of the SPTGI demonstrates strong reliability and validity among clinical nurses and can serve as an effective tool to evaluate the secondary posttraumatic growth of clinical nurses in China.
