Abstract
Background
From a notion concentrated on the ability to understand health information, health literacy (HL) has become a broad concept, considered a critical determinant of community health. The HLS-EU-measures perceived HL based on a theoretical model of the concept.
Methods
This study explored the metric properties of the tool in a new European setting among a convenience sample of 300 healthcare users in a state General Hospital, including the construct and known-group validity by social position and health-related behaviours.
Results
While factor analysis did not reveal the 12 theoretical subscales, there was a meaningful 3-factor structure (52.1% variance): “access to information”, “prevention and health promotion” and “user-provider interaction”. The postulated four cognitive skills (access, understand, appraise, apply) were evident within each domain (healthcare, prevention, health promotion), and vice versa. Overall, HL was problematic in 50.7% of participants with a steep gradient by social position. Alcohol consumption and physical activity were associated with HL, but not being overweight (mean BMI 26.8, SD: 5.2) or smoking (45.6% current or past smokers), which were generally prevalent.
Conclusions
HLS-EU-Q47 supports at least partly the theoretical construct of HL. The social gradient supports the criterion validity of the tool and highlights an important aspect of health inequality.
Key messages
HLS-EU-Q47 is a valid measure of perceived health literacy
There was a steep gradient in low health literacy by social position
