Psychometric evaluation of the Persian version of the European Health Literacy Instrument (P-HLS-EU-Q47).

Health literacy is one of the most critical determinants of health for effectively improving health services and reducing health inequalities. The importance of accurate measurement cannot be overstated. The European 47-item Health Literacy Questionnaire (HLS-EU-Q47) can provide precise measurements of health literacy. Therefore, this study aimed to evaluate the psychometric properties of the European Health Literacy Instrument in Iranian society (HLS-PV-Q47) for its Persian version. This cross-sectional study was conducted using a convenient sampling of 560 people referred to comprehensive healthcare centers. The construct validity was assessed by exploratory (280 people) and confirmatory factor (with 280 people). The internal consistency was calculated using Cronbach's alpha coefficients. Based on the exploratory factor analysis, three factors of healthcare, disease prevention, and health promotion explained 48.9% of the total variance of health literacy. Cronbach's alpha was 0.96 for the whole instrument. The Persian version of the European Health Literacy Instrument (P-HLS-EU-Q47) had good validity and reliability, which can be used in future studies due to its good psychometric properties.

HLS19-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 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.

Measuring Comprehensive, General Health Literacy in the General Adult Population: The Development and Validation of the HLS19-Q12 Instrument in Seventeen Countries.

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.

The HLS19-COM-P, a New Instrument for Measuring Communicative Health Literacy in Interaction with Physicians: Development and Validation in Nine European Countries.

BACKGROUND: Sufficient communicative health literacy (COM-HL) is important for patients actively participating in dialogue with physicians, expressing their needs and desires for treatment, and asking clarifying questions. There is a lack of instruments combining communication and HL proficiency. Hence, the aim was to establish an instrument with sufficient psychometric properties for measuring COM-HL. METHODS: The HLS19-COM-P instrument was developed based on a conceptual framework integrating HL with central communicative tasks. Data were collected using different data collection modes in nine countries from December 2019 to January 2021 (n = 18,674). Psychometric properties were assessed using Rasch analysis and confirmatory factor analysis. Cronbach's alpha and Person separation index were considered for reliability. RESULTS: The 11-item version (HLS19-COM-P-Q11) and its short version of six items (HLS19-COM-P-Q6) fit sufficiently the unidimensional partial credit Rasch model, obtained acceptable goodness-of-fit indices and high reliability. Two items tend to under-discriminate. Few items displayed differential item functioning (DIF) across person factors, and there was no consistent pattern in DIF across countries. All items had ordered response categories. CONCLUSIONS: The HLS19-COM-P instrument was well accepted in nine countries, in different data collection modes, and could be used to measure COM-HL.

Organizational Health Literacy in Schools: Concept Development for Health-Literate Schools.

(1) Background: Health literacy is considered a personal asset, important for meeting health-related challenges of the 21st century. Measures for assisting students' health literacy development and improving health outcomes can be implemented in the school setting. First, this is achieved by providing students with learning opportunities to foster their personal health literacy, thus supporting behavior change. Second, it is achieved by measures at the organizational level promoting social change within the proximal and distal environment and supporting the school in becoming more health-literate. The latter approach is rooted in the concept of organizational health literacy, which comprises a settings-based approach aiming at changing organizational conditions to enhance health literacy of relevant stakeholders. The HeLit-Schools project aims to develop the concept of health-literate schools, describing aspects that need to be addressed for a school to become a health-literate organization. (2) Method: The concept development builds on existing concepts of organizational health literacy and its adaptation to the school setting. (3) Results: The adaptation results in the HeLit-Schools concept describing a health-literate school with eight standards. Each standard depicts an area within the school organization that can be developed for fostering health literacy of school-related persons. (4) Conclusions: The HeLit-Schools concept offers an approach to organizational development for sustainably strengthening health literacy.

Adaptation of the Health Literacy Survey Questionnaire (HLS19-Q) for Russian-Speaking Populations-International Collaboration across Germany, Israel, Kazakhstan, Russia, and the USA.

The Russian language is the eighth most spoken language in the world. Russian speakers reside in Russia, across the former Soviet Union republics, and comprise one of the largest populations of international migrants. However, little is known about their health literacy (HL) and there is limited research on HL instruments in the Russian language. The purpose of this study was to adapt the Health Literacy Questionnaire (HLS19-Q) developed within the Health Literacy Survey 2019-2021 (HLS19) to the Russian language to study HL in Russian-speaking populations in Germany, Israel, Kazakhstan, Russia, and the USA. The HLS19-Q was translated either from English or from a national language to Russian in four countries first and then critically reviewed by three Russian-speaking experts for consensus. The HLS19 protocol and "team approach" method were used for linguistic and cultural adaptation. The most challenging was the adaptation of HLS19-Q questions to each country's healthcare system while general HL questions were flexible and adaptable to specific contexts across all countries. This study provides recommendations for the linguistic and cultural adaptation of HLS19-Q into different languages and can serve as an example of international collaboration towards this end.

The effect of self-efficacy on health literacy in the German population.

Concerning the determinants of health literacy (HL) mostly socio-demographic or -economic factors have been considered, much less so psychological factors such as self-efficacy. To date, it has mostly been considered to explain the relationship of HL and health outcomes. However, self-efficacy could also be an important determinant for HL. This study therefore examines the effect of self-efficacy on comprehensive HL within the general population in Germany. Data from the German HL Survey (HLS-GER), a cross-sectional, computer-assisted personal interview study among 2000 respondents aged 15+ years in 2014 were used. Self-efficacy was measured using the German version of general self-efficacy short scale (ASKU), comprehensive HL was measured using the German version of the European Health Literacy Survey Questionnaire (HLS-EU-Q47). Correlation and multi-variate linear regression analyses were performed to analyze independent effects of socio-demographic factors-age, gender, social status, educational level and migration background-functional HL and self-efficacy on comprehensive HL. Self-efficacy and comprehensive HL are statistically significantly correlated (Spearman's Rho = 0.405; p < 0.01), respondents with better self-efficacy had better HL scores. Both concepts are significantly associated with most socio-demographic factors and functional HL. Self-efficacy showed the strongest association with HL in the multivariate analyses (model 2: ß =0.310, p < 0.001). The effect size of the other predictors decreased, when adding self-efficacy into the equation, but remained statistically significant. Self-efficacy is a rather strong predictor of comprehensive HL. Future research and measures to improve HL should therefore take self-efficacy adequately into account.

Challenges in Navigating the Health Care System: Development of an Instrument Measuring Navigation Health Literacy.

Due to their rapid expansion and complexity, it is increasingly difficult for patients to orient themselves in health care systems. Therefore, patients require a high degree of health literacy, or more precisely, navigation health literacy (HL-NAV). The actual extent of HL-NAV of patients and citizens is still largely unknown due to the lack of adequate measurement instruments. Thus, within the new international Health Literacy Population Survey 2019 (HLS19), one aim was to develop a suitable instrument for measuring HL-NAV in the HLS19 the HL-NAV-HLS19. The item development was conducted by an international working group within the HLS19 Consortium led by the first and last authors. Methodologically, it is based on a scoping literature review, development of a conceptual framework for HL-NAV, and first item formation, as well as an evaluation by experts, stakeholders, focus groups, pre-test interviews, and continuously feedback from the HLS19 Consortium. HL-NAV was defined as the ability to access, understand, appraise, and apply information on navigational issues, drawing on ten selected publications and the health literacy definition of the HLS-EU Consortium. Main tasks of HL-NAV at the system, organization, and interaction level were identified, to which first related items were assigned. Based on the feedback from experts, the focus group discussions, and the HLS19 Consortium, the instrument was slightly revised. Finally, twelve items proved to be feasible in the pre-test. The instrument will be used for the first time in the HLS19 survey and will provide first data on HL-NAV in general populations for the countries participating in HLS19. It is suited for cross-country comparisons and monitoring, as well as for intervention development. However, the instrument should be translated into and validated in further languages and countries for population samples.

Health Literacy Measurement in General and Other Populations: Further Initiatives and Lessons Learned in Europe (and Beyond).

This chapter provides an overview of health literacy measurement initiatives with a focus on the European Health Literacy Survey (HLS-EU) - describing where measuring population health literacy started, where it currently is, and providing an outlook to the upcoming European HL survey. In the first part of the chapter, the methodology and the main results of the initial HLS-EU study from 2011 will be introduced. In the second part the worldwide impact of the HLS-EU study will be mapped. Many publications and studies used the HLS-EU instruments in the original or few in an adapted way to measure comprehensive health literacy - in many different settings and in diverse countries. Finally, the chapter ends with an outlook to the M-POHL and HLS19 initiatives of WHO-Europe which are intended to advance HLS-EU as well as the measurement of population and organizational health literacy in a more coordinated, standardized, and institutionalized manner.

Development and Validation of a Self-Assessment Tool for an Integrative Model of Health Promotion in Hospitals: Taiwan's Experience.

The Health Promotion Administration of Taiwan launched an integrative certification initiative in 2016 to streamline a plural system of certifications of health promotion in hospitals. It endeavored to replace original certifications, thereby establishing the proposal of a self-assessment instrument to aid in this integration. This study aimed to verify the robustness of this self-assessment tool by conducting exploratory factor analyses through stratification, reliability tests, content and construct validity tests, and specialist evaluations, which were convened to judge the comprehensibility, applicability, and importance of the standards and measures of this tool. A stratified random sampling of 46 hospitals was performed to confirm the validity of this tool. The tool rendered a floor effect of 0% and a ceiling effect of 13%. A valid factor structure and internal consistency (α ranged from 0.88 to 0.96) in each standard were verified. Hospitals with previous certificates or with 300+ beds achieved high compliance scores. A majority of experts agreed that the sub-standards were comprehensible (≥80%), applicable (≥70%), and important (≥70%). Finally, we conclude that the self-assessment tool is valid and can serve as a reference for other countries with hospitals committed to health promotion in hospital settings.
