Abstract

Background and Purpose: Nursing students have an essential role in patient safety. The purpose of this study was to evaluate the face validity, content validity, and psychometric properties of the Hospital Survey on Patient Safety Culture for Nursing Students (HSOPS-NS). Methods: The cross-sectional study was carried out between January and October 2021. The participants were undergraduate nursing students (N = 482) from 16 Czech nursing faculties. Results: Exploratory factor analysis revealed an eight-factor structure, which was verified by confirmatory factor analysis using the optimization process that results in adequate goodness-of-fit indices (root mean squared error approximation = .037; standardized root mean squared residuals = .056; comparative fit index = .935; Tucker-Lewis index = .926; incremental fit index = .936). The internal consistency of a new model was excellent (α = .914). Conclusion: The results indicate that the HSOPS-NS shows evidence of reliability and validity and is a valuable measure of safety culture as perceived by nursing students.
