Researchers Update Digital Health Literacy Instrument
Rosalie van der Vaart et al. publish on April 1, 2026 an updated Digital Health Literacy Instrument (DHLI 2.0) and a 16-item short form, validated using a June 2024 online survey of 2,728 representative Dutch panel members. Both full and short forms show high internal consistency (α=0.94 and α=0.90), cover eight domains including data security, and correlate as expected with age, education, income, and online time, supporting use in research and eHealth practice.
Key Points
- 1Validate DHLI 2.0 (24 items, eight domains) and 16-item short form in N=2,728 sample
- 2Show high internal consistency (α=0.94 full, α=0.90 short), supporting measurement reliability
- 3Indicate digital safety items moderate reliability, signalling need for caution when assessing privacy competencies
Scoring Rationale
This is a timely, peer-reviewed measurement update with strong psychometrics in a large representative sample, increasing novelty and credibility. Scored 8.3 for high relevance and direct usability in research and eHealth; not higher because it is an instrument refinement rather than a paradigm shift.
