Background: Health literacy has become a global issue, and patients and individuals have access to health information and educational services by using information technology. The role of electronic media in health promotion has become increasingly important in recent years. Using information technology for health requires eHealth literacy, including the ability to read, use computers, search for information, understand health information, and put it into context. At present, researches on eHealth literacy at home and abroad are gradually maturing and the number of researches is increasing, but the status quo of the eHealth Literacy scale is still unclear.

Objectives: To understand the existing scales of eHealth literacy at home and abroad and to provide a theoretical basis for the further investigation of residents' level of electronic health literacy.

Methods: We systematically searched PubMed, EMBASE, MEDLINE, Cochrane Library, CNKI, CBM, VIP, and WAN FANG database. We included “eHealth literacy”, “E-health literacy”, “electronic health literacy” and “scale” to search and extracted the first author, year of publication, name of the country, the study population, name of scale, entries of Containing, scores, and so on. The literature screening and data extraction carried out by four reviewers independently by using EndNote software. Any conflicts in the results are discussed after careful discussion. Statistical analyses will be conducted with SPSS 24.0.

Results: This study is ongoing, and all results will be presented at the Cochrane Colloquium as available.

Conclusions: This study is ongoing, and all results will be presented at the Cochrane Colloquium as available.
