Abstract
Background: It is of great significance for brain and heart health managers to assess the electronic health literacy of people at high risk of stroke for improving the current situation of stroke in China. Although various measuring instruments have been developed, there is still a lack of suitable tools to match the development of network.Aim: To examine the reliability and validity of the electronic Health Literacy Scale（e-HLS）among people at high risk of stroke in China, so as to provide appropriate measurement tools for brain heart health managers.Methods: A demographic questionnaire, the electronic Health Literacy Scale（e-HLS）and the eHealth Literacy Scale (eHEALS) were administered to a sample of 648 people at high risk of stroke recruited from November to December 2020 in a tertiary hospital.Results: The Cronbach’α coefficient on the e-HLS-CHI was 0.91. Three factors were extracted by Exploratory Factor Analysis (EFA), accounting for 90.84% of the total variance. Confirmatory Factory Analysis (CFA) revealed that three factors of e-HLS-CHI fit well ( NFI = 0.979, RFI = 0.955, IFI = 0.987, TLI = 0.972, CFI=0.987, RMSEA = 0.070, CMIN/DF= 2.586). Good simultaneous validity was suggested by the positive correlation of 0.94 between the e-HLS-CHI and eHEALS. And when using eHEALS as the standard, the area under the ROC curve of e-HLS-CHI was 0.896 (95% CI: 0.831-0.960, P = 0.000). After calculation, the sensitivity and specificity were 97.8% and 70.4% respectively, indicating that it has nice predictive validity.Conclusions: The e-HLS can be used to evaluate electronic health literacy of people at high risk of stroke in China. This may be helpful for brain and heart health managers to assess the current situation of electronic health literacy in people at high risk of stroke and provide reference for future health promotion programs.
