Abstract
Aim The aim of the study was to understand nurses' information security attitudes towards patient information. This study developed the Information Security Attitude Questionnaire (ISA‐Q) to measure the physical, technical and administrative aspects of information security for nurses and assessed its validity and reliability. Design Cross‐sectional study and scale development. Methods Exploratory and confirmatory factor analyses and correlation analyses were performed to assess construct, discriminant and convergent validity; Cronbach's α and test–retest reliability were examined. Results Exploratory and confirmatory factor analyses yielded a 6‐factor, 30‐item solution. Six factors accounted for 60.19% of the total variance. The confirmatory factor analysis was achieved through structural equation modelling. Discriminant and convergent validity were confirmed. The internal consistency of the ISA‐Q was 0.94, and the test–retest reliability was 0.74. The ISA‐Q is an appropriate questionnaire for identifying information security attitudes of nurses, making it useful for developing systematic performance methods to enhance nurses' information security levels.
