Abstract: Objective: To translate the Modified Information Security Behavior Measurement Scale, and to verify its reliability and validity among nurses in China, so as to provide a tool for assessing information security behavior of Chinese nurses. Methods: After obtaining the authorization from the author of the original scale, the translation, back-translation, cross-cultural adaptation and pre-survey were completed based on the Brislin translation model. The validity and reliability of the Chinese version of the scale was assessed among 823 nurses from 8 hospitals in Shandong province and Henan province through convenience sampling from October to December 2024. Results: The Chinese version of the Modified Information Security Behavior Measurement Scale has three dimensions with 18 items. The I-CVI of the scale ranged from 0.875 to 1.000, and S-CVI was 0.973. Exploratory factor analysis extracted 4 common factors, with a cumulative variance contribution rate of 57.353%. The final model fit indices of confirmatory factor analysis were as follows: χ2/df=3.881, RMSEA=0.084, CFI=0.904, NFI=0.876, GFI=0.880. The Cronbach's α coefficient of the total scale was 0.854, the test-retest reliability was 0.983, and the split-half reliability was 0.754. Conclusion: The Chinese version of the Modified Information Security Behavior Measurement Scale has good reliability and validity, and can be used as an effective tool for evaluating the information security behavior of nurses in China.
