Conclusions
As digital technology continues to advance rapidly, the concept of digital literacy is constantly evolving with it. We developed a digital literacy measure, the EDLQ, that incorporates the latest definitions of digital literacy and validated its psychometric properties. The EDLQ holds potential for application in both research and practice settings, particularly for evaluating the digital literacy of community-dwelling older adults living in South Korea. However, to fully broaden the scope of its future use, further examinations to assess its applicability to different languages and cultures are warranted. Further empirical research on the digital literacy of older adults and associated factors is also necessary to foster the development of person-centered digital health care services and educational interventions for older adults in the digital society.This research was supported by the Basic Science Research Program through the National Research Foundation of Korea and funded by the Ministry of Education (2020R1A6A1A03041989).Authors' Contributions: JC conceptualized and supervised the study.
