The entire world is faced with the COVID-19 pandemic, which is also accompanied by an infodemic. This refers to the rapid spread of (accurate and false) information, mainly through internet usage increasing. Digital health literacy (DHL) is therefore important for addressing challenges related to online health information and services, as well as for navigation through the complex information landscape with huge amounts of different (and conflicting) information about COVID-19. The aim of this study is to examine the level of DHL in relation to COVID-19 in Slovenian university students and to determine online information-seeking behaviour in order to plan and prepare effective communication interventions for this sub-population. A cross-sectional survey, administered by an online questionnaire, was conducted to collect data on DHL. A total of 3621 students participated, of whom 70% were female and the average age was 22.65 years (SD = 4.65). Bivariate analyses were performed to assess the association of key characteristics with DHL. Overall, the results show that the level of DHL among students is sufficient. Most difficulties were reported in assessing the reliability of information (n = 1484, 49.3%). Approximately one third of the students (n = 847, 27.9%) reported having problems in finding information of their interest, and somewhat more (n = 900, 29.6%) reported difficulties in making a selection among all the information found. Students with a sufficient level of DHL are more likely to seek information through search engines and websites of official institutions, while students with a limited level of DHL more frequently reported using social media for health information searches. It is necessary to establish interventions for a systematic lift of the DHL and health literacy (HL) of all population groups.

Our research demonstrated that the STOP can be applied to the field of vaccination. There is a huge need for intensive professional communication about vaccination on the internet and social media. The improvement of the communicational competences of doctors and healthcare workers is essential to achieve better communication with parents and the media, and needs to be focused on mothers and pregnant women.

Background: For improving health literacy (HL) by national and international public health policy, measuring population HL by a comprehensive instrument is needed. A short instrument, the HLS19-Q12 based on the HLS-EU-Q47, was developed, translated, applied, and validated in 17 countries in the WHO European Region. Methods: For factorial validity/dimensionality, Cronbach alphas, confirmatory factor analysis (CFA), Rasch model (RM), and Partial Credit Model (PCM) were used. For discriminant validity, correlation analysis, and for concurrent predictive validity, linear regression analysis were carried out. Results: The Cronbach alpha coefficients are above 0.7. The fit indices for the single-factor CFAs indicate a good model fit. Some items show differential item functioning in certain country data sets. The regression analyses demonstrate an association of the HLS19-Q12 score with social determinants and selected consequences of HL. The HLS19-Q12 score correlates sufficiently highly (r ≥ 0.897) with the equivalent score for the HLS19-Q47 long form. Conclusions: The HLS19-Q12, based on a comprehensive understanding of HL, shows acceptable psychometric and validity characteristics for different languages, country contexts, and methods of data collection, and is suitable for measuring HL in general, national, adult populations. There are also indications for further improvement of the instrument.

Background Due to the digital transformation in late modern society, digital (or e-) health literacy (DHL) is becoming increasingly relevant for people to take health related decisions. Yet despite its importance for evidence-based policy, very few tools have been developed to measure DHL, and even fewer studies have measured DHL in general populations. The Action Network on Measuring Population and Organizational Health Literacy (M-POHL) is one of the first to include a measure of DHL and its relevant correlates in the Health Literacy Survey 2019 (HLS19). Methods Based on an existing instrument (Van der Vaart & Drossaert, 2017), adapted to the format of the HLS-EU questionnaire for measuring comprehensive health literacy, 10 items with four Likert categories were developed to measure self-reported DHL, as well as 6 questions measuring the use of digital resources to obtain health related information and communicate with their health care system, as an optional package of the HLS19 study. Ten of the 15 countries participating in HLS19 included this optional package into their national survey. Data were collected from probability samples of at least 1.000 respondents per country, taken from the general population 18+ by personal interviews, telephone interviews or internet. Results For comparisons between countries, distributions of the answers to single items as well as psychometric validation and descriptive data for an index of DHL will be presented. Associations of DHL with general comprehensive health literacy, with the use of digital resources, and with other selected correlates based on correlational and regression analysis will also be presented comparatively for countries. Conclusions This study is the first to present standardized comparative data for the distributions of DHL and its correlates in the general population of WHO-Europe region Member States. The relevance of these results for national and European health policy will be discussed.
