PY22280Health literacy measurement: a comparison of four widely used health literacy instruments (TOFHLA, NVS, HLS-EU and HLQ) and implications for practice
It is unknown whether health literacy instruments measure the same health literacy construct. This study compares psychometric properties and correlations between four widely used instruments: two performance-based functional health literacy instruments (Test of Functional Health Literacy in Adults and Newest Vital Sign) and two self-report multidimensional instruments (European Health Literacy Survey and Health Literacy Questionnaire). New insight into the different constructs these instruments measure and implications for their application in research, policy, and clinical practice is presented.
