Abstract: Objective　To develop a digital literacy scale for university teachers and test its reliability and validity.Methods　Referring to the industry standard Teacher Digital Literacy, an initial item pool of the digital literacy scale for medical university teachers was constructed. From June 2024 to September 2024, a survey was conducted among 218 in-service teachers of different majors from a medical university in Tianjin. Item analysis, construct validity, and convergent validity were used to verify the reliability and validity of the scale.Results　The digital literacy scale for university teachers includes 5 first-level dimensions (digital awareness, digital technology knowledge and skills, digital application, digital social responsibility, and professional development) and 32 second-level dimensions. Exploratory factor analysis identified 5 common factors, namely digital awareness, digital technology knowledge and skills, digital application, digital social responsibility, and professional development, with a cumulative variance explanation rate of 83.76%. The overall Cronbach's α coefficient of the scale was 0.978, and the Cronbach's α coefficients of each dimension were all greater than 0.8.Conclusion　The digital literacy scale for university teachers has good reliability and validity, and is suitable for evaluating the digital literacy level of medical university teachers in the era of digital transformation in China.
