HLS-NAV-Validation of a New Instrument Measuring Navigational Health Literacy in Eight European Countries.

To manoeuvre a complex and fragmented health care system, people need sufficient navigational health literacy (NAV-HL). The objective of this study was to validate the HLS-NAV measurement scale applied in the European Health Literacy Population Survey 2019-2021 (HLS). From December 2019 to January 2021, data on NAV-HL was collected in eight European countries.
