A Systematic Review of Questionnaire Measuring eHealth Literacy

Abstract

Purpose: This review aims to summarize the characteristics of currently used questionnaires measuring eHealth literacy and assess the quality of their psychometric properties in self-reported assessments within community settings. Methods: The systematic analysis was conducted using the COnsensus-based Standards for the selection of health Measurement INstruments checklist to evaluate the methodological quality of studies on measurement properties. Results: A total of 21 studies, including 19 questionnaires, were reviewed. The findings indicated that the quality of psychometric assessments for eHealth literacy was generally rated as 'good,' with most studies addressing multiple aspects of reliability and validity. Internal reliability, content validity, hypothesis testing, and responsiveness were particularly well-supported, each receiving over 10 sufficient ratings. However, there was limited evidence regarding measurement errors, test-retest reliability, criterion validity, and analyses of floor and ceiling effects. Conclusion: This study contributes to the enhancement of eHealth literacy measurement tool selection and improves the reporting of their validity and reliability, thereby increasing the credibility of future research.
