Association Between eHealth Literacy and Health Outcomes in German Athletes using the GR-eHEALS Questionnaire: A Validation and Outcome Study

This data set was collected to examine the eHealth Literacy Scale as a means of assessing eHealth literacy among German athletes. In this context, we pursued two objectives with this study: first, to test the factorial structure of the GR-eHEALS and assess its construct validity by examining both convergent and discriminant validity; and second, to examine the associations between eHealth literacy and health-related outcomes (i.e., substance use and injuries). This digital survey was conducted as a cross-sectional study, adhering to the approval guidelines of the Ethics Committee of the Faculty of Medicine at the University of Duisburg-Essen (19-8947-BO). Prior to the survey, each participant provided electronic informed consent. Participation was both anonymous and voluntary, without any form of reimbursement. We utilized the Unipark software (Tivian XI GmbH) that was distributed through social media, sports clubs (involving athletes competing in regional and nationwide tournaments), and sports associations (both regional and nationwide) from December 2021 to December 2022.
