Abstract:

Objective To develop a safety culture assessment scale for nursing training laboratories in colleges and universities and evaluate its reliability and validity. Methods Based on the Haddon and Reason models，the initial scale was constructed via literature review，semi-structured interviews，and two rounds of expert consultation. A convenience sample of 604 nursing students at an university completed the questionnaire between October 2025 and February 2026 for reliability and validity testing. Results The final scale consisted of 50 items. Exploratory factor analysis extracted 6 factors（safety attitudes and values，safety management and system perception，safety behavior and emergency response，safety interaction and improvement，overall satisfaction，and safety negative cognition）. The cumulative variance explained was 68.45%. Confirmatory factor analysis indicated good model fit （χ²/df=2.89，CFI=0.901，TLI=0.919，RMSEA=0.067，SRMR=0.045）. The total scale’s Cronbach’s α was 0.952，with subscales ranging from 0.852 to 0.943；test-retest reliability was 0.865. The AVE values ranged from 0.54 to 0.73，the composite reliability ranged from 0.85 to 0.92，and convergent validity was adequate. Conclusion The newly developed safety culture scale for nursing training laboratories demonstrates good reliability and validity.
