- HLS19-DIGI - a new instrument for measuring digital health literacy: development, validation and associations with determinants and health outcomes in 13 countriesPublication . the HLS19 Consortium of the WHO Action Network M-POHL; Levin-Zamir, Diane; Broucke, Stephan Van den; Bíró, Éva; Bøggild, Henrik; Bruton, Lucy; Gani, Saskia Maria De; Finbråten, Hanne Søberg; Gibney, Sarah; Griebler, Robert; Griese, Lennert; Guttersrud, Øystein; Klocháňová, Zuzana; Kucera, Zdenek; Le, Christopher; Link, Thomas; Mancini, Julien; Miksova, Dominika; Schaeffer, Doris; Silva, Carlota Ribeiro da; Sørensen, Kristine; Straßmayr, Christa; Arriaga, Miguel Telo de; Vrdelja, Mitja; Pelikan, JürgenIntroduction: Digital health information sources are playing an increasingly prominent role in health promotion, public health and in healthcare systems. Consequently, digital health literacy skills are likewise becoming increasingly important. Methods: Using a concept validation approach, the aim of the study was to validate a digital health literacy measure applied in the European Health Literacy Survey 2019–2021 (HLS19) of the WHO M-POHL Network, analyzing data from 28,057 respondents from 13 European countries. Results: The scale displayed high internal consistency. Confirmatory factor analysis (CFA) strengthened the hypothesized one-factor structure. In most countries, the data displayed acceptable fit to the unidimensional Rasch partial credit model (PCM). Pearson correlation with a measure of general health literacy showed sufficient discriminant validity, and a social gradient was found. Testing for predictive validity showed that the scale score predicts health-related outcomes. Discussion: The study shows that considerable proportions of the general adult populations across countries in Europe have limited DHL skills. The level of DHL has direct potential consequences for some forms of health service utilization, in some countries. Implications of the study include recommendations for improving digital health literacy, promoting organizational health literacy and quality assurance for digital health information and resources.
- HLS19-NAV - validation of a new instrument measuring navigational health literacy in eight European countriesPublication . on behalf of the HLS Consortium; Griese, Lennert; Finbråten, Hanne S.; Francisco, Rita; Gani, Saskia M. de; Griebler, Robert; Guttersrud, Øystein; Jaks, Rebecca; Le, Christopher; Link, Thomas; Costa, Andreia Silva da; Arriaga, Miguel Telo de; Touzani, Rajae; Vrdelja, Mitja; Pelikan, Jürgen M.; Schaeffer, DorisTo 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 HLS19-NAV measurement scale applied in the European Health Literacy Population Survey 2019–2021 (HLS19). From December 2019 to January 2021, data on NAV-HL was collected in eight European countries. The HLS19-NAV was translated into seven languages and successfully applied in and validated for eight countries, where language and survey method differed. The psychometric properties of the scale were assessed using confirmatory factor analysis (CFA) and Rasch modelling. The tested CFA models sufficiently well described the observed correlation structures. In most countries, the NAV-HL data displayed acceptable fit to the unidimensional Rasch partial credit model (PCM). For some countries, some items showed poor data–model fit when tested against the PCM, and some items displayed differential item functioning for selected person factors. The HLS19-NAV demonstrated high internal consistency. To ensure content validity, the HLS19-NAV was developed based on a conceptual framework. As an estimate of discriminant validity, the Pearson correlations between the NAV-HL and general health literacy (GEN-HL) scales were computed. Concurrent predictive validity was estimated by testing whether the HLS19-NAV, like general HL measures, follows a social gradient and whether it forms a predictor of general health status as a health-related outcome of general HL. In some countries, adjustments at the item level may be beneficial.
