Researchers Validate Three-Factor eHEALS Digital Health Literacy
Researchers analyzed 2022 GetCheckedOnline survey data from 1,657 sexually active British Columbia residents to reassess the eHealth Literacy Scale (eHEALS). Using polychoric exploratory and confirmatory factor analyses, they identified three dimensions—Information Navigation, Resource Appraisal, and Confidence in Use—with strong fit (CFI 0.969, RMSEA 0.059) and reliability. The multidimensional model improves measurement precision for identifying limited digital health literacy and targeting interventions.
Key Points
- 1Identify three eHEALS factors: Information Navigation, Resource Appraisal, Confidence in Use from 1,657 respondents.
- 2Demonstrate multidimensional validity with CFA fit indices (CFI 0.969, RMSEA 0.059) indicating strong model fit.
- 3Enable more precise DHL measurement to inform equity-oriented interventions and target populations with low digital access.
Scoring Rationale
Strong psychometric validation and actionable multidimensional model, limited by single-region sample and need for broader demographic validation.
