Generic health literacy measurement instruments for children and adolescents: a systematic review of the literature

Measuring General Health Literacy in Chinese adults: validation of the HLS19-Q12 instrument

BACKGROUND

Health literacy measurement lays a solid foundation to identify associations with health outcomes and monitor population health literacy levels over time. In mainland China, most existing health literacy instruments are either knowledge-based or practice-based, making health literacy results incomparable between China and other countries. This study aimed to examine the reliability and validity of the 12-item Health Literacy Population Survey (HLS19-Q12) in a general population of Chinese adults.

METHODS

A cross-sectional study was conducted to recruit primary carers of students from 11 schools in Zhengzhou, Henan Province, using convenience cluster sampling. Participants completed an online self-administered survey that collected information on key sociodemographics, health literacy (HLS19-Q12 and a comparison tool: Health Literacy Questionnaire (HLQ)), and health-related outcomes. Using the COnsensus-based Standards for the selection of health status Measurement Instruments (COSMIN) checklist as a guideline, we tested internal consistency, test-retest reliability, content validity, structural validity, concurrent predictive validity, and convergent validity of the HLS19-Q12.

RESULTS

Overall, 14,184 participants completed the full survey. The HLS19-Q12 showed excellent internal consistency (Cronbach's α = 0.93), moderate test-retest reliability (intra-class correlation coefficient = 0.54), satisfactory content validity (based on the 12-matrix health literacy model), and strong structural validity (comparative fit index = 0.94, Tucker and Lewis's index of fit = 0.93, root mean square error of approximation = 0.095). Concurrent predictive validity results showed health literacy was associated with both health determinants and health-related outcomes. The HLS19-Q12 had weak to strong correlations (coefficients = 0.24 to 0.42) with the nine scales of the HLQ. Respondents had an average score of 81.6 (± 23.0) when using the HLS19-Q12, with 35.0% and 7.5% having problematic and inadequate levels of health literacy, respectively.

CONCLUSIONS

The HLS19-Q12 is a reliable and valid instrument to measure health literacy in our sample. Further validation is needed with a more nationally representative sample of Chinese adults. The HLS19-Q12 could be used as a comprehensive, skills-based, and easy-to-administer health literacy assessment tool integrated into population surveys and intervention evaluations.

Adolescents' understanding of the Nepalese version of HLS-CHILD-Q15: qualitative pre-testing in ninth-graders

INTRODUCTION

Research on health literacy is still at an early stage, lacking a dedicated measurement instrument for assessing children's and adolescents' health literacy. Such tools are necessary to generate the evidence required for informed intervention development. This study translated the validated German HLS-Child-Q15 into the Nepalese context, creating the HLS-Child-Q22-NEP.

METHODS

The research team initially created the HLS-Child-Q22-NEP using an additional item pool. We conducted thirteen one-on-one cognitive interviews with adolescent students from community schools in three districts of Nepal during the pre-test. We employed verbal probing techniques and deductively analysed the interviews based on Tourneau's model, uncovering four main themes: (1) comprehension (with the two sub-categories: a) item comprehension and b) word comprehension); (2) retrieval; (3) judgement; and (4) response.

RESULTS

Overall, participants responded positively to the HLS-Child-Q22-NEP. However, this study revealed comprehension challenges such as unfamiliarity, misunderstandings, and translation issues. Additionally, the study identified retrieval challenges and poor judgement, indicating limitations in the assessment. Participants experienced varying levels of difficulty with some items, emphasising the need for revised instructions. Subsequent revisions, guided by pretest insights, led to the development of the HLS-Child-Q24-NEP.

CONCLUSION

The development of the HLS-Child-Q22-NEP is a significant step in addressing Nepali adolescents' lack of health literacy measurement. Despite its generally positive reception, this study encountered challenges in comprehending the scale, prompting enhancements, and developing the HLS-Child-Q24-NEP. Further research, both qualitative and quantitative, is necessary to evaluate the validity and reliability of the modified items.

Health literacy in the context of child health promotion: a scoping review of conceptualizations and descriptions

BACKGROUND

Increasing health literacy (HL) in children could be an opportunity for a more health literate future generation. The aim of this scoping review is to provide an overview of how HL is conceptualized and described in the context of health promotion in 9-12-year-old children.

METHODS

A systematic and comprehensive search for 'health literacy' and 'children' and 'measure' was performed in accordance with PRISMA ScR in PubMed, Embase.com and via Ebsco in CINAHL, APA PsycInfo and ERIC. Two reviewers independently screened titles and abstracts and evaluated full-text publications regarding eligibility. Data was extracted systematically, and the extracted descriptions of HL were analyzed qualitatively using deductive analysis based on previously published HL definitions.

RESULTS

The search provided 5,401 original titles, of which 26 eligible publications were included. We found a wide variation of descriptions of learning outcomes as well as competencies for HL. Most HL descriptions could be linked to commonly used definitions of HL in the literature, and some combined several HL dimensions. The descriptions varied between HL dimensions and were not always relevant to health promotion. The educational setting plays a prominent role in HL regarding health promotion.

CONCLUSION

The description of HL is truly diverse and complex encompassing a wide range of topics. We recommend adopting a comprehensive and integrated approach to describe HL dimensions, particularly in the context of health promotion for children. By considering the diverse dimensions of HL and its integration within educational programs, children can learn HL skills and competencies from an early age.

Using co-design to develop the Adolescent Health Literacy Questionnaire for adolescents in Ireland

Health literacy measurement studies are important for the success of health promotion efforts targeting adolescents. However, the majority of health literacy measurement tools were originally developed for adult populations and may not be reflective of health literacy in the context of adolescence. The present study sought to co-design a health literacy questionnaire and vignettes for adolescents in Ireland aged 12-18 years. This article describes the qualitative phase of the study. In 2019-2021, eight adolescents from the Irish Heart Foundation's Youth Advisory Panel participated in two concept mapping workshops during which they defined healthy living. Results of the thematic analysis indicated that adolescents defined 'healthy living' as a life that was balanced, prioritizing mental health and sleep. According to their definition, healthy living was comprised of six main constructs, namely, knowledge; sources of quality health information; facilitators and barriers; influence of others; self-efficacy, self-management and resilience; and citizenship and communication. These constructs were used to develop vignettes and items for the Adolescent Health Literacy Questionnaire (AHLQ). These were tested on a sample of 80 adolescents to check whether the respondents understood the items and vignettes as intended. Results of the nine cognitive interviews indicated that the adolescents understood the content of the 10 vignettes and 41 items. While the vignettes and AHLQ were developed with Irish adolescents, the approaches taken can be generalized to adolescents living in other countries. This will allow for the development of tailored and relevant solutions for health literacy development and health promotion for this sub-population.

Evaluation of cross-cultural adaptation and validation of the Persian version of the health literacy for school-aged children scale: Methodological study

Background and Aims

Health literacy (HL) is an essential determinant of health in children. Inadequate HL causes problems for individuals and society, such as more hospitalizations, medication errors, poor health, and higher mortality and health care costs. A valid and reliable scale is needed to measure this population's HL. This study evaluated the cross-cultural adaptation and validation of the Persian version of the HL for School-Aged Children (HLSAC) Scale.

Methods

In this methodological research, the HL scale of school-aged children was translated from English to Persian using the Backward-Forward translation protocol. The content validity, face validity, construct validity (Exploratory Factor Analysis [EFA] and Confirmatory factor analysis [CFA]), plus reliability, were evaluated by Internal consistency and stability methods. Two hundred forty samples from south of Tehran were selected by multi-stage sampling method to assess the construct validity. Data analysis was performed using SPSS v24 and Jamovi v2.2.

Results

A qualitative evaluation of face and content validity showed that experts and the target group approved all items on the scale. The results of EFA indicated the existence of one factor, explaining 47.17% of the total variance of the scale. The CFA results showed that the one-factor model of the Persian version of the HL scale for children is almost acceptable. (χ 2/df = 2.94, Root Mean Square Error of Approximation = 0.09, Normed-Fit Index = 0.89, Tucker-Lewis Index = 0.89, Comparative Fit Index = 0.92). Cronbach's alpha coefficient for the whole scale was 0.80, and the Intraclass Correlation Coefficient value for the whole scale was calculated as 0.78 using the single-rating, absolute-agreement, 2-way mixed-effects method.

Conclusion

The study validates the HLSAC Scale, affirming its suitability for assessing HL in Persian-speaking child populations.

Measuring adolescent health literacy in Taiwan: validation of the health literacy assessment scale for adolescents

BACKGROUND

This study aimed to validate the Chinese version of the Health Literacy Assessment Scale for Adolescents (HAS-A) and conduct a comparative analysis of adolescent health literacy between Taiwan and other countries.

METHODS

The Chinese version of the HAS-A was completed by 2,312 adolescents in the fifth and sixth grades of a primary school. Psychometric properties were examined using consistent internal reliability and confirmatory factor analysis. These assessments were compared with the results from different regions to explore health literacy inequality.

RESULTS

Construct validity was good, and internal consistency was acceptable. The scale, particularly regarding communication health literacy, was associated with parents' socioeconomic status, and family income had a more significant impact on children's health literacy than community income. Health literacy disparities appear in different countries, with Taiwan exhibiting the lowest level of communication health literacy.

CONCLUSION

The results indicate that the HAS-A is a valuable tool for assessing the health literacy of 10-11-year-old adolescents and can uncover health literacy inequality among different regions.

Developing the pediatric surgery patient satisfaction scale and assessment of its validity and reliability

Aim of this study was to develop a patient satisfaction scale for needs and expectations of pediatric surgery patients and to propose a new measurement tool in this field. Population of study consisted of all patients between May 2018 and February 2020 at a pediatric surgery service of a university hospital in Turkey. A pool of 70 items was prepared for scale. Two items were removed in line with expert opinions and suggestions. As a result of content validity and test application, 36 items were removed, and scale was revised. Data were transferred to SPSS Statistics 23 and AMOS 22 program. After evaluating scope validity of scale, Content Validity, Structural Validity, Exploratory Factor Analysis, and finally Reliability Analysis were examined. As a result of the analyses, 32 items with eight sub-dimensions were obtained from scale. Eight-factor scale explained 60.42% of total variance. Cronbach Alpha internal consistency of scale was found to be 0.88. Item factor loads of scale were created and the reliability of scale were obtained at desired level. The scale is suitable for patients aged 6 to 18 years old.

Understanding Critical Health Literacy Among Adolescents: Psychometric Properties of the CHLA Questionnaire in Lower Secondary Schools in Norway

BACKGROUND

Schools are important arenas for the promotion of critical health literacy (CHL) among adolescents. Key domains of CHL are information appraisal, understanding social determinants of health, and abilities to act on determinants of health. In this paper, we examine the psychometric properties of the Critical Health Literacy for Adolescents Questionnaire (CHLA-Q).

METHODS

A cross-sectional survey study was performed at 5 schools in Norway. Respondents included 522 pupils aged 13-15 years old. Confirmatory factor analysis (CFA) was conducted to examine the structural validity. Internal reliability was assessed using ordinal Cronbach's alpha.

RESULTS

The estimated model had acceptable closeness of fit. Five of 6 scales displayed adequate internal reliability.

CONCLUSION

The results indicate acceptable fit of the CHLA-Q framework and that 5 of the 6 scales are applicable to inform future research and interventions. More research is needed on measurement of the second domain of CHL.

Development of health literacy assessment tool for 9-10 Years old children in Thailand

Objectives

This study developed psychometric evaluation of an instrument for measuring health literacy among children in Thailand.

Study design

Development of Health Literacy Assessment Tool for 9-10 Years Old Children in Thailand involved item development. The first step was reviewing literature to pilot-test and generate an item pool. Nine expertise with different disciplines were approached to assess the initial questionnaire. For field-testing, 1650 students with same age group were randomly selected to complete the questionnaire. The psychometric properties of the developed instrument were assessed by an Exploratory Factor Analysis (EFA) and a Confirmatory Factor Analysis (CFA).

Results

A total of 50-items were included in exploratory factor analysis indicating 4-dimension solution that jointly explained 36.05% of the variance observed. Confirmatory factory analysis also indicated a good fit of the data for the four-latent structure: access to information (9-items), understanding the information (6-items), appraisal (8-items), and apply the information (9-items) (Chi-square: χ2 = 1530.76), (Goodness-of-Fit Index: GFI = 0.937), (Adjust GFI: AGFI = 0.927), (Standardized root mean-square residual: SRMR = 0.025); (Root mean-square error of Approximation: RMSEA = 0.040), (Comparative-fit-Index: CFI = 0.903) and (Normed-fit-index: NFI = 0.910). Additional analysis for internal consistency observed satisfactory results with overall Cronbach's alpha coefficient of 0.902. The Item-Total Correlation (ITC) was 0.300 (range:0.319 to 0.518) and high validation with value of CVI of 0.87.

Conclusions

Health Literacy Assessment Tool for 9-10 Years Old children (31-item) showed psychometric properties, high validityy and was reliable. Therefore, it is considered as an effective tool to measure the Health Literacy for 9-10 years old children in Thailand.

Are childhood factors predictive of adult health literacy? A longitudinal birth cohort analysis

Health literacy (HL), defined as the ability of an individual to understand and appraise health information to make informed decisions on their health, helps maintain and improve one's health and thus reduce the use of healthcare services. There is a recognised global effort to address insufficient HL in early life and understand how HL develops. This study examined the association of a range of factors including educational, speech and language ability, health and healthcare engagement, sleep problems, mental health, demographic, environmental, and maternal factors at different childhood stages (from 5 years to 11 years) with later adult HL at age 25. HL was measured using a HL ordinal score (insufficient, limited, or sufficient) derived from the European Literacy Survey Questionnaire-short version (HLS-EU-Q16) within a large UK based birth cohort (Avon Longitudinal Study of Parents and Children: ALSPAC study). Univariate proportional odds logistic regression models for the probability of having higher levels of HL were developed. Results of analysis of 4248 participants showed that poorer speech and language ability (aged 9 years, OR 0.18 95% CI 0.04 to 0.78), internalising in child (age 11 years, OR 0.62 95% CI 0.5 to 0.78), child depression (age 9 years, OR 0.67 95% CI 0.52 to 0.86), and the presence of maternal depression (child age 5, OR 0.80 95% CI 0.66 to 0.96), reduced the odds of sufficient HL when adult. Our results suggest some useful markers to identify children at potential risk of low HL that could be targeted for research into future interventions within school settings, for example, child's speech and language capability. In addition, this study identified child and maternal mental health as factors associated with later development of limited HL and future research should consider what potential mechanisms might explain this link.

Developing Healthy Lifestyle Behaviors in Early Age-An Intervention Study in Kindergartens

Childhood obesity prevention is a leading public health challenge requiring the adoption of healthy lifestyles at an early age. We examined how the kindergarten environment can promote eating sensibly, drinking water and becoming physically active. The effects of an intervention program among 42 Israeli kindergartens (1048 children, aged 4-6) whose teachers participated in a health education training program were compared to 32 kindergartens (842 children) whose teachers did not undergo this training program. An eight-month intervention program focused on knowledge/mathematical/logical/critical thinking, self-regulation/control acquisition, and sensible decision-making abilities. We hypothesized that nutrition and physical-exercise-oriented intervention programs, combining knowledge/mathematical logical thinking, would positively impact the quality of children's mid-morning snack and water consumption, their ability to express feelings following physical exercise, and the adoption of healthy lifestyles at home. The quality of mid-morning snacks and water consumption were observed in both groups pre- and post-intervention. Qualitative interviews documented children's subjective feelings following physical exercise. A significant improvement (p < 0.001) was observed in the mid-morning snacks composition and in water drinking habits in the intervention group; 80% of children offered a physiological explanation regarding energy expenditure processes following intense physical exercise. In conclusion, kindergarten interventions implemented by trained teachers can promote adoption of health behaviors necessary for obesity prevention.

The experiences of siblings of children with chronic illness of health-related communication directed at them: a systematic review protocol and thematic synthesis of qualitative studies

The psychological, social and financial impact that chronic illness can have on a family and in particular the siblings of children with chronic illness (SCWCI) is well documented. Siblings are at risk of a variety of psychosocial and physical problems such as suffering from anxiety, experiencing headaches, appetite loss. However, the experiences with health-related communication of SCWCI is not well known. This may leave them with suboptimal information. The aim of this systematic review described in this protocol is to understand SCWCI experience of targeted health-related communication; detailing the communication strategies utilised, how helpful the information was and what they wish would be different. The Preferred Reporting Items for Systematic reviews and Meta-analysis for Protocols (PRISMA-P) checklist will be used to frame this protocol. Registration: PROSPERO (393998, 03 February 2023).

Improving adolescent health literacy through school-based health literacy intervention: a mixed-method study protocol

BACKGROUND

Health-promoting actions might benefit from adolescent health literacy (AHL), however, there is scant research on it in Nepal. This study identifies adolescent students' health literacy (HL) needs and trials an intervention to improve their HL and intention to take health-promoting actions.

METHODS

This study employs a pre-and post-test mixed-method intervention involving three phases. First, we will conduct a formative and summative evaluation to identify participants' HL needs and design an intervention using quantitative and qualitative methods. Second, the intervention will be administered to the intervention group. Finally, formative and summative post-tests will be conducted to assess the effectiveness of the intervention. We will select four community schools from Birendranagar municipality based on random sampling. In quantitative research, data will be collected from adolescents selected through a census with standardized scales such as the HLS-Child-Q15, self-efficacy, social support, and health-promoting actions. A framework analysis was conducted to analyze qualitative data collected from focus group discussions with purposively chosen adolescents and key informant interviews with Health and Physical Education teachers and school nurses. The difference in difference approach will be used to analyze the intervention's outcome, i.e., the participants' improved HL, and health-promoting actions.

DISCUSSION

This is one of the first studies to explore HL in this group in Nepal. This study will provide the first insights into the overall level of AHL, potential AHL determinants, and the relationship between AHL and the intention to participate in health-promoting activities. The data can then be used to inform health promotion and health literacy initiatives.

Evaluating student's ability to assess treatment claims: validating a German version of the Claim Evaluation Tools

BACKGROUND

The Claim Evaluation Tools measure the ability to assess claims about treatment effects. The aim of this study was to adapt the German item sets to the target group of secondary school students (aged 11 to 16 years, grade 6 to 10) and to validate them accordingly. The scale's reliability and validity using Rasch's probabilistic test theory should be determined.

METHODS

We conducted a sequential mixed-method study comprising three stages: contextualisation and adaption of the items (stage 1), piloting of the item sets using qualitative interviews (stage 2) and a construct validation by testing the unidimensional Rasch scalability for each item set after data collection in one secondary school in Germany and two secondary schools in Austria. We explored summary and individual fit statistics and performed a distractor analysis (stage 3).

RESULTS

Secondary school students (n = 6) and their teachers (n = 5) participated in qualitative interviews in Germany. The qualitative interviews identified the need for minor modifications (e.g. reducing thematic repetitions, changing the order of the items). The data of 598 German and Austrian secondary school students were included to test for Rasch scalability. Rasch analyses showed acceptable overall model fit. Distractor analyses suggested that model fit could be improved by simplifying the text in the scenarios, removing and editing response options of some items.

CONCLUSION

After the revision of some items, the questionnaires are suitable to evaluate secondary school students' ability to assess health claims. A future goal is to increase the pool of items being translated and tested.

Validation of the brief instrument "Health Literacy for School-Aged Children" (HLSAC) among Norwegian adolescents

Health literacy (HL) has been identified as an important and modifiable determinant of health. To succeed in promoting HL, it is crucial to evaluate interventions addressing HL using validated instruments. However, HL measurement is an under-researched area among adolescents. The Health Literacy for School-Aged Children (HLSAC) scale is developed in Finland to measure the subjective HL levels of school-aged children. The HLSAC has been used and validated across Europe. No validated instrument for measuring HL among Norwegian adolescents has been identified. Therefore, the aim of this study was to assess the psychometric properties of the HLSAC among Norwegian adolescents in upper secondary schools. Cross-sectional data were collected in 2017 from 1 054 adolescents with a response rate of 93.5%. The participants were students aged 16-21 (mean = 17.3) years from four upper secondary schools in an urban area in Mid-Norway. Confirmatory factor analysis (CFA) was utilized to investigate the underlying dimensionality of the data together with composite reliability based on Raykov's reliability coefficient and certain aspects of construct validity. The original ten-item one-dimensional version of the HLSAC revealed a poor fit. A one-dimensional version including six of the original ten items presented the best fit to our data, demonstrating good reliability and construct validity. This validation study suggests a one-dimensional solution of the HLSAC scale including six of the original ten items, i.e., the HLSAC-6 as a statistical valid and reliable measure for HL among adolescents in upper secondary schools. However, the modifications of the instrument indicate the need for further investigation of the HLSAC in this age group, i.e. by conducting cognitive interviews and focus-group discussions on the concept of HL among adolescents. Testing the wording of the HLSAC prior to additional psychometric evaluations of both the original HLSAC and the suggested HLSAC-6 is recommended. Finally, developing more age-appropriate items for the measurement of HL in this age-group is suggested.

Developing the HLS19-YP12 for measuring health literacy in young people: a latent trait analysis using Rasch modelling and confirmatory factor analysis

BACKGROUND

Accurate and precise measures of health literacy (HL) is supportive for health policy making, tailoring health service design, and ensuring equitable access to health services. According to research, valid and reliable unidimensional HL measurement instruments explicitly targeted at young people (YP) are scarce. Thus, this study aims at assessing the psychometric properties of existing unidimensional instruments and developing an HL instrument suitable for YP aged 16-25 years.

METHODS

Applying the HLS₁₉-Q47 in computer-assisted telephone interviews, we collected data in a representative sample comprising 890 YP aged 16-25 years in Norway. Applying the partial credit parameterization of the unidimensional Rasch model for polytomous data (PCM) and confirmatory factor analysis (CFA) with categorical variables, we evaluated the psychometric properties of the short versions of the HLS₁₉-Q47; HLS₁₉-Q12, HLS₁₉-SF12, and HLS₁₉-Q12-NO. A new 12-item short version for measuring HL in YP, HLS₁₉-YP12, is suggested.

RESULTS

The HLS₁₉-Q12 did not display sufficient fit to the PCM, and the HLS₁₉-SF12 was not sufficiently unidimensional. Relative to the PCM, some items in the HLS₁₉-Q12, the HLS₁₉-SF12, and the HLS₁₉-Q12-NO discriminated poorly between participants at high and at low locations on the underlying latent trait. We observed disordered response categories for some items in the HLS₁₉-Q12 and the HLS₁₉-SF12. A few items in the HLS₁₉-Q12, the HLS₁₉-SF12, and the HLS₁₉-Q12-NO displayed either uniform or non-uniform differential item functioning. Applying one-factorial CFA, none of the aforementioned short versions achieved exact fit in terms of non-significant model chi-square statistic, or approximate fit in terms of SRMR ≤ .080 and all entries ≤ .10 that were observed in the respective residual matrix. The newly suggested parsimonious 12-item scale, HLS₁₉-YP12, displayed sufficiently fit to the PCM and achieved approximate fit using one-factorial CFA.

CONCLUSIONS

Compared to other parsimonious 12-item short versions of HLS₁₉-Q47, the HLS₁₉-YP12 has superior psychometric properties and unconditionally proved its unidimensionality. The HLS₁₉-YP12 offers an efficient and much-needed screening tool for use among YP, which is likely a useful application in processes towards the development and evaluation of health policy and public health work, as well as for use in clinical settings.

Promoting food literacy in primary school classrooms through the HealthLit4Kids Program in Australia

Food literacy (FL) refers to the knowledge, skills, and behaviours associated with healthy eating. Schools are recognised as an important setting for FL promotion during childhood. HealthLit4Kids is an Australian primary school intervention that engages students, families, and educators to promote health literacy. This study aimed to assess the promotion of FL, a subtype of health literacy, in primary school classrooms across five schools. Teachers planned and implemented classroom activities over a 12-month period. Researchers examined lesson plans created by teachers and ‘artefacts’ (e.g. drawings, models) created by students during activities. Most classroom activities considered the nutritional knowledge and interpersonal communication skills associated with healthy eating, whereas fewer activities addressed students’ ability to critically analyse and apply information relating to food. The FL themes considered most frequently in classroom activities were ‘food and health choices’, ‘knowledge’, and ‘skills and behaviour’. Whereas the FL themes considered less frequently were ‘food systems’, ‘emotion’, and ‘culture’. The delivery of classroom activities was supported by the integration of other curriculum areas (e.g. The Arts and English). Future studies are required to understand how school-based interventions can promote the areas of FL that were less frequently addressed in this intervention in the classroom and beyond.

Measuring Health Literacy in Basic Education in Finland: The Development of a Curriculum- and Performance-Based Measurement Instrument

This paper describes the development of an objective curriculum- and performance-based health literacy (HL) measurement instrument to assess Finnish 9th graders' learning outcomes in the school subject termed Health Education (HE). There were four phases: (i) construction of the theoretical framework for the measurement, (ii) item generation, (iii) the field test (n = 252), and (iv) item analysis and item selection for the main study, in which 3652 ninth grade pupils (aged 15-16) participated. Initially, 303 HL test items were formulated, of which 107 were tested in two different field test versions. Both versions exhibited high reliability as measured by Cronbach's alpha coefficient. The main study contained 55 items. Testing and item analysis enabled the development of a comprehensive competence- and curriculum-based HL measurement instrument for school-aged children. Measurement of HL in schools provides information for national policies, and for developing HE as a school subject.

Investigating knowledge structure and research trends in child and adolescent health literacy research through network text analysis

PURPOSE

This study aims to investigate the knowledge structure and research trends in child and adolescent health literacy research over the past 30 years by using network text analysis.

METHOD

The study was conducted in four steps: 1) collecting abstracts, 2) keyword extraction and preprocessing, 3) creation of co-occurrence matrix, and 4) text network analysis.

RESULTS

As a result of the centrality analysis, the upper-ranked core keywords were "health care," "health behavior," "prevention," "treatment," and "health promotion." In contrast to earlier times, "barrier," "caregiver," "school setting," and "QOL" have recently emerged as core keywords.

CONCLUSIONS

Over the past 30 years, child and adolescent health literacy has been importantly addressed in both clinical and public health approaches. The results of the current study provide references for future research in child and adolescent health literacy.

IMPLICATION FOR PRACTICE AND RESEARCH

This study suggests the need for additional research on school-based practices that can improve health literacy and for identifying validated and reliable multidimensional health literacy assessment instruments.

Development and validation of an instrument for the health literacy assessment of secondary school students (HeLiASeSS)

Purpose

The development of health literacy skills is of paramount importance especially for students, as it is associated with their wellbeing and academic success. Assessing students' health literacy is necessary for its advancement. This study comes to fill the need for a valid multidimensional health literacy assessment instrument for secondary school students.

Design/methodology/approach

Initially, the authors defined the conceptual framework within which the items of this instrument were generated. Its final form was obtained through three pilot studies. A test-retest followed and, finally, a nationwide survey was conducted on Greek seventh-, ninth- and tenth-grade students (N = 2,800).

Findings

A 37-item instrument, the Health Literacy Assessment for Secondary School Students (HeLiASeSS), was developed which includes the following nine dimensions/skills of health literacy: “access to”, “understand” and “evaluate” (health information), “functional communication”, “interactive communication” and “critical communication”, “relying on health information”, “self-efficacy regarding health matters” and “intention for active citizenship regarding health matters”. HeLiASeSS proved to have good stability (ICC = 0.943) and high internal consistency reliability (a = 0.903).

Originality/value

HeLiASeSS offers the possibility of a reliable and valid assessment of secondary school students' health literacy skills providing a multidimensional evaluation of this construct and is expected to be useful in interventions aiming at promoting this type of literacy.

Community health literacy outcome measurement practices: A scoping review of recent interventions

Introduction

Evidence suggests that, while a preference for functional Health Literacy (HL) outcome measurement exists, researchers are converging towards more all-encompassing instruments. While this claim is present in the HL field, minimal research has comprehensively explored the state of community HL measurement practices at the direct and proxy level. The almost exclusive focus on direct, as opposed to proxy, community HL measurement indicates a review of progress is needed.

Objective

To identify HL outcome measurement practices for community HL interventions at the direct and proxy level of measurement.

Search Strategy

Medline, PsycINFO, Web of Science, ERIC, Embase, Scopus, CINAHL, ProQuest Dissertations and Theses, Google Scholar and targeted websites were searched.

Inclusion Criteria

Studies were sampled from the general population, included HL as an outcome of interest, involved an intervention aiming to improve HL, were English-text publications and were published ≥2010.

Data Extraction and Synthesis

Study author(s) and publication years, sample characteristics, intervention profiles and direct and proxy instrument and outcome measurement information were extracted. Full-text review retrieved 25 eligible studies.

Main Results

In total, 21 unique direct and 38 unique proxy instruments were extracted. The majority of interventions assessed functional compared to communicative, critical, and other HL domains, with objective instruments more frequently used than subjective or combined objective-subjective types, though more unique subjective HL instruments were extracted overall. The Test of Functional HL in Adults was the most popular instrument, and perceived health, knowledge, behaviors and health intentions were the most frequent proxy outcome measures, with only the Healthy Lifestyle Behavior Scale-II and Patient Activation Measure used across multiple interventions.

Discussion and Conclusions

Direct HL outcome practices endured a unidimensional profile, despite previous suggestions of a convergence towards holistic instruments. This review provides the first overview of proxy HL measurement across community HL interventions, identifying substantial variation in proxy outcome practices.

Patient or Public Contribution

A University-based senior librarian contributed to the development of the search strategy, and reviewed iterations of the strategy until refinement was complete. No further public or patient contribution was made given the review-based nature of the research.

Comparison of Health Literacy Assessment Tools among Beijing School-Aged Children

Health literacy is a broad and multidimensional construct, making its measurement and conclusions inconsistent. This study aims to compare the patterning of health literacy using different assessment tools and examine their impact on children’s developmental outcomes. A cross-sectional study was conducted with 650 students in Years 7–9 from four secondary schools in Beijing. Health literacy was measured by the eight-item health literacy assessment tool (HLAT, score range 0–37), the six-item Newest Vital Sign (NVS, score range 0–6), and the 16-item Health Literacy Survey (HLS, score range 0–16). Based on Manganello’s health literacy framework, information on upstream factors (e.g., gender, ethnicity, socioeconomic status) and developmental outcomes (e.g., health-promoting behaviours, health service use, global health status) was collected. Overall, the average scores for health literacy were 26.34 ± 5.89, 3.64 ± 1.64, and 13.72 ± 2.94, respectively, for HLAT, NVS, and HLS. The distribution of health literacy varied by socio-demographics and individual characteristics except for gender, no matter which health literacy assessment tool was used. The magnitude of associations between health literacy, its upstream factors and developmental outcomes was greater when using three-domain instruments (HLAT and HLS) than using single-domain instruments (NVS). The approach to health literacy measurement will influence the conclusion. Using multidimensional assessment tools may better capture a child’s health literacy and contribute to the maximum efficiency and effectiveness of school-based health literacy interventions.

Measuring health literacy: A systematic review and bibliometric analysis of instruments from 1993 to 2021

BACKGROUND

It has been about 30 years since the first health literacy instrument was developed. This study aimed to review all existing instruments to summarize the current knowledge on the development of existing measurement instruments and their possible translation and validation in other languages different from the original languages.

METHODS

The review was conducted using PubMed, Web of Science, Scopus, and Google Scholar on all published papers on health literacy instrument development and psychometric properties in English biomedical journals from 1993 to the end of 2021.

RESULTS

The findings were summarized and synthesized on several headings, including general instruments, condition specific health literacy instruments (disease & content), population- specific instruments, and electronic health. Overall, 4848 citations were retrieved. After removing duplicates (n = 2336) and non-related papers (n = 2175), 361 studies (162 papers introducing an instrument and 199 papers reporting translation and psychometric properties of an original instrument) were selected for the final review. The original instruments included 39 general health literacy instruments, 90 condition specific (disease or content) health literacy instruments, 22 population- specific instruments, and 11 electronic health literacy instruments. Almost all papers reported reliability and validity, and the findings indicated that most existing health literacy instruments benefit from some relatively good psychometric properties.

CONCLUSION

This review highlighted that there were more than enough instruments for measuring health literacy. In addition, we found that a number of instruments did not report psychometric properties sufficiently. However, evidence suggest that well developed instruments and those reported adequate measures of validation could be helpful if appropriately selected based on objectives of a given study. Perhaps an authorized institution such as World Health Organization should take responsibility and provide a clear guideline for measuring health literacy as appropriate.

Children's Health Literacy in Relation to Their BMI z-Score, Food Intake, and Physical Activity: A Cross-Sectional Study among 8-11-Year-Old Children in The Netherlands

Overweight and obesity in children are an increasing public health problem. Health literacy (HL) is a determinant of obesity and body mass index (BMI) rates in adults, but few studies have addressed the impact of children’s own HL on their weight and lifestyle. In this study, we aim to assess the impact of Dutch children’s HL on (1) their BMI z-score, (2) dietary behaviour, and (3) the amount of physical activity (PA) they engage in. A sample of 139 children (age 8–11 years) filled out a digital questionnaire, including an HL measurement instrument and questions regarding their food intake and PA. Furthermore, the height and weight of the children were measured, and background information was collected using a parental questionnaire. Multiple regression revealed a significant positive relation between children’s HL and their PA. No significant association between children’s HL and their BMI z-score or dietary behaviour was found. HL of children in primary school thus has an impact on some aspects of children’s lifestyle, although more research in a larger, more diverse sample is needed to further investigate this.

Wissen schafft Gesundheit: Das Programm „Fit in Gesundheitsfragen“ zur Stärkung der Gesundheitskompetenz von Schülerinnen und Schülern

In Deutschland weist mehr als die Hälfte der Bevölkerung eine geringe Gesundheitskompetenz auf. Diese Menschen haben Schwierigkeiten, gesundheitsrelevante Informationen zu finden, einzuordnen und anzuwenden. Unter ihnen sind auch viele junge Menschen, was den Stellenwert früher Interventionen zur Förderung der Gesundheitskompetenz verdeutlicht.

Das Programm „Fit in Gesundheitsfragen“ der Gesundheitsinformationsdienste vom Forschungszentrum Helmholtz Munich und dem Deutschen Krebsforschungszentrum hat zum Ziel, einen Beitrag zur Förderung verschiedener Dimensionen von Gesundheitskompetenz bei Kindern und Jugendlichen zu leisten. Dazu werden innovative Fortbildungsformate für Lehrkräfte und Unterrichtsmaterialien für Lernende der Sekundarstufen I und II konzipiert und begleitend evaluiert. Am Modell der Volkskrankheiten Krebs und Diabetes mellitus wird Wissen zu deren Entstehung, Prävention, Behandlung und Erforschung vermittelt. Darüber hinaus werden Wissen über das Gesundheitssystem und Materialien zur Förderung der Gesundheitskompetenz bereitgestellt. Die Evaluation erhebt Indikatoren zu Reichweite und Akzeptanz der Maßnahmen.

Seit 2018 wurden 46 Unterrichtsmaterialien und 3 Informationsschriften mit Hintergrundwissen für Lehrende veröffentlicht. Ferner wurden 50 Lehrerfortbildungen durchgeführt, an denen bis Ende 2021 rund 1600 Lehrkräfte und Multiplikatoren in Präsenz oder online teilnahmen. Sie erteilten den jeweiligen Veranstaltungen zu über 90 % sehr gute und gute Noten. Rund 80 % der Teilnehmenden gaben an, die vermittelten Themen in ihrem Unterricht aufgreifen zu wollen. Ein weiterer Ausbau des Angebots ist vorgesehen. Die Testung ausgewählter Materialien im Hinblick auf die Förderung der Gesundheitskompetenz in einer Stichprobe von Lernenden ist in Planung.

Development of an Instrument to Measure Dietary Supplement Health Literacy

Background:

Health literacy is one of the important social determinants of health.

Objective:

The aim of this study was to develop an instrument to measure Dietary Supplement Health Literacy (DSHL) of Iranian women.

Methods:

In this psychometrics study, an initial nine-factor instrument was developed. Face validity and content validity of the instrument were evaluated. The factor structure of the instrument was explored by the Exploratory Factor Analysis (EFA) among 400 women taking Dietary supplement. Confirmatory Factor Analysis (CFA) was done to determine the underlying factor structure of the instrument in this population. The internal and external reliability of the instrument was evaluated.

Key Results:

According to expert panel opinions, 16 items were deleted. The results of the EFA showed that the Kaiser-Meyer-Olkin and Bartlett's test of sphericity were significant. EFA showed that 30 items could be grouped into nine factors that accounted for 60.84% of the variance. Since two items in the ability to actively engage with health care providers factor were loaded in factor 1, this factor was labeled Engaging in receiving informational supports from health care providers. In addition, one item of the dimension was loaded in factor 3. Given that the one item of factor 5 and 1 item of factor 6 were loaded in a new factor 9, this factor was labeled Applying information to decision-making. The CFA indicated that the nine-factor structure of the DSHL instrument had a poor fit. To modify indices, factor 9 with 2 items and 1 item of factor 6 were deleted. The Cronbach's alpha and intraclass correlation coefficient of the instrument were acceptable. Finally, a 27-item instrument with 8 dimensions was confirmed.

Conclusions:

The results of the study showed that the instrument developed was a valid tool for identifying the DSHL of Iranian women. [HLRP: Health Literacy Research and Practice. 2022;6(2):e159–e166.]

Plain Language Summary:

This study sought to develop and validate a multidimensional instrument to measure the health literacy of Iranian women about dietary supplements that was performed from July 2019 to May 2020 in Iran. Findings showed that the 30-item instrument developed in this study is a valid instrument to be used for identifying the health literacy of Iranian women about dietary supplements.

Developing Indicators to Measure Critical Health Literacy in the Context of Norwegian Lower Secondary Schools

A critical health literacy (CHL) approach is recommended for promoting health in the school context. This construct is complex and includes three interconnected domains: (A) appraisal of critical information, (B) awareness of the social determinants of health (SDH), and (C) collective action to promote health and well-being. In recent literature reviews, no measurement instrument that covers all three domains of CHL in the school-context was found. Our aim was to develop self-reported measurement scales for each domain of CHL. The development process reported in this study was conducted in two stages. In the first stage, an initial item pool was generated based on literature reviews and focus group interviews (N = 15) with adolescents (steps 1–2). In the next steps, items were adjusted and removed based on the feedback from an expert panel and from representatives from the target group (steps 3–5). In stage two, we aimed to reduce the number of items and develop scales for each domain. We then piloted the current draft, which consists of 28 items (N = 114). A sub-sample (N = 10) of the participants were interviewed after they completed the survey to examine the instrument’s face validity. Cronbach’s α was used to assess the internal reliability of the scales; the reliability was promising for scales A (α = 0.83) and C (α = 0.85) but was below the recommended value for scale B (α = 0.61). The model fit indices were promising (TLI_scaleA = 0.97, RSMEA_scaleA = 0.055, TLI_scaleB = 1.05, RMSEA_scaleB = 0.00, TLI_scaleC = 0.95, RMSEA_scaleC = 0.074). The piloted version of scales A and C were positively correlated with subjective health literacy, health-related quality of life, and subjective health; however, we found no such correlations for scale B. The post-survey group interviews led to some adjustments in scales A and B. The revised version of CHLA-Q must be tested using a larger sample; this will enable more robust statistical testing of the properties of the items and the scale.

Development and Validation of an Oral Health Literacy Measurement for Primary School Children in Thailand

Background

Oral health promotion programs have been implemented in primary schools for many years in Thailand. Oral health literacy has been introduced as a health promotion outcome; however, no assessment tool has been developed for this age group. The objective of this study was to develop and validate the Test of Functional Health Literacy in Dentistry for Primary School Children (P-TOFHLiD). Materials and Methods. The P-TOFHLiD was developed by modifying contents and outlines using a previously validated tool for older adults, then verified by two experts for face validity. A cross-sectional study was conducted with samples collected from 118 grade-six students from two government schools in Chiang Mai Province, Thailand. The P-TOFHLiD and a previously validated word recognition test were administered, followed by oral examination to assess reliability, concurrent validity, convergent validity, and predictive validity and establish the cut-off score of the tool. The statistical analysis was performed using SPSS version 25.

Results

The internal reliability of P-TOFHLiD was good (α = 0.808). The correlation coefficient between the P-TOFHLiD and grade point average was 0.478 (p value <0.001), which is the represented concurrent validity of the tool. Coefficients between P-TOFHLiD and a word recognition test was 0.422 (p-value <0.001) for convergent validity. P-TOFHLiD was significantly correlated with the number of missing teeth from tooth decay (p-value <0.05), but the correlation coefficient was poor (r = −0.100). The cut-off scores for adequate oral health literacy were set at ≥21 out of the total scores of 26.

Conclusion

P-TOFHLiD presented good validity and reliability and was ready to use for oral health promotion program evaluation. However, the predictive validity of the P-TOFHLiD in predicting oral health status was questionable only.

International Understandings of Health Literacy in Childhood and Adolescence—A Qualitative-Explorative Analysis of Global Expert Interviews

(1) Background: With regard to children and adolescents, health literacy should only not be understood as an individual ability, but rather as dependent based on its contextual determinants. The study examines how experts define health literacy in childhood and adolescence and discusses whether they include these factors. (2) Methods: In 48 interviews with experts from 32 countries, specific questions for defining health literacy in childhood and adolescence were analyzed. Data analysis was conducted according to the summary of the qualitative content analysis. Main categories and subcategories were developed exploratively and inductively. (3) Results: No expert had an official definition of health literacy in childhood or adolescence. There were more experts who located health literacy only at the individual level alone than those who located it at both the individual and contextual levels. On the individual level, there was a focus on information processing, knowledge, behavior, and skills. At the contextual level, system responsibility, the ability of others, and relationship between age and development were the main points. (4) Conclusions: To develop an adequate method of dealing with health literacy in the target group, there must be a target group-specific consideration of the dependencies, ages, and developmental stages of that group. While this is considered as consensus in scientific discourse, it has seemingly not yet been adopted in development-related policies internationally.

Translation and Validation of a Brief Health Literacy Instrument for School-Age Children in a Danish Context

Low health literacy (HL) is associated with adverse health behaviors and poor health, and brief, high-quality instruments for measuring HL in children are scarce. The Health Literacy for School-Aged Children (HLSAC) instrument is a 10-item theory-based and internationally validated tool for measuring HL. The purpose of this study was to translate and validate the HLSAC instrument among Danish school-aged children. The instrument was translated into Danish by a standardized forward-backward translation process, and then pre-tested for face validity with 61 pupils from four schools. Thereafter, the instrument was tested among 805 pupils in grades 6 to 7 (age 11–14 years) from 15 schools. When HL was modeled as one latent factor with all 10 items loading on this factor, the confirmative factor analysis showed standardized factor loadings from 0.52 to 0.75 (p < .001) and an excellent model fit. The association between HL and food intake as a health behavior example (p < .001, r² = .027) indicates the predictive validity of the instrument. The internal consistency was high (Cronbach's alpha = 0.86). Thus, a valid and reliable version of the HLSAC instrument is available in Danish for future surveys to monitor HL and guide health promotion targeting children and adolescents.

The Role of Health Literacy in Health Behavior, Health Service Use, Health Outcomes, and Empowerment in Pediatric Patients with Chronic Disease: A Systematic Review

About 8% of all children and adolescents worldwide are affected by chronic diseases. Managing chronic conditions requires pediatric patients to be health literate. The purpose of this review is to examine the existing evidence on the links between health literacy and its outcomes proposed by the model by Sørensen et al. in chronically ill pediatric patients. Four electronic databases (PubMed, Scopus, CINAHL, PsycINFO) were searched to identify pertinent articles published up to November 2021. The search was conducted independently by two researchers and restricted to observational studies. Of 11,137 initial results, 11 articles met eligibility criteria. Overall, 6 studies identified a significant association between health literacy and one of the considered outcomes. Regarding health behavior, none of the studies on adherence found significant associations with health literacy. The results in terms of health service use were inconclusive. Regarding health outcomes, health literacy did not affect most physiological parameters, but it significantly improved health-related quality of life. Overall, evidence remains inconclusive but suggests that health literacy is associated with self-efficacy, health-related quality of life, and health service use in pediatric patients. Further research should be undertaken to strengthen the evidence.

Socio-Economic Determinants of Health Literacy in High School Students: A Cross-Sectional Study

Today, a person’s health literacy (HL) is perceived as a critical determinant for their health. It is well known that limited health literacy is associated with harmful health behaviours, the lower use of preventive services, problems in making use of healthcare resources and poor skills for the self-management of chronic disorders. This study analysed the level and factors associated with HL in high school students in southern Poland. The study is based on the data from a paper-and-pencil survey of high schools students in the Malopolska Voivodshop. The students were selected using a two-stage cluster random sampling procedure. The level of HL was assessed with the European Health Literacy Survey Questionnaire, consisting of 47 items. Univariate logistic and linear regression models were applied to analyse the association between general HL score and the main domain-specific indices. The respondents whose parents had attended University and came from more affluent families were less likely to demonstrate limited HL. There was a significant positive relationship between the self-assessment of the economic situation, size of accommodation, the level of expenditure on a mobile phone and receiving external support, the size of the book collection at home, and domain-specific HL sub-indices. In conclusion, among socio-demographic factors, the parents’ education is the only consistent predictor of the level of HL in high school students. Furthermore, most variables reflecting the economic status of the respondent’s family are significantly associated with the general HL score and its sub-indices.

Developing performance-based measures of health literacy: A narrative case study and checklist of considerations

Research in health literacy is fundamentally impacted by our ability to adequately assess the construct. Although various measures of health literacy have been developed, there are few reflective discussions of the challenges and learnings from the instrument development process. This is somewhat surprising given that health literacy is a multi-dimensional and contested concept (with inherent measurement challenges), and that there are important practical considerations owing to the fact that people completing health literacy assessments may have lower general literacy (i.e. ability to read and write) and English-language skills. This paper discusses our learnings from developing a performance-based measure of parenting health literacy skills (the Parenting Plus Skills Index). The performance-based instrument is characterised by its grounding in health literacy as asset, with items spanning Nutbeam's functional, communicative and critical health literacy skills, and was designed chiefly to capture improvements resulting from health literacy skills training. This paper elucidates critical junctures in the development process, particularly regarding the conceptualisation and operationalisation of the construct. We also outline our approach to addressing practical measurement issues (e.g. administration time; item difficulty). In summarising these, we offer a 13-item checklist to inform the development of health literacy instruments for other health contexts or health conditions.

A Study on the Reliability and Validity of the Korean Health Literacy Instrument for Late School-Aged Children

This study aimed to develop and validate the Korean Health Literacy Instrument, which measures Korean late school-aged children's understanding capacity. The construct's concepts were drawn from the literature review and interviews with school nurses and teachers. A survey was then conducted in 552 fifth and sixth graders in nine elementary schools, from 1 to 9 May 2014. The KR-20 coefficient for reliability, difficulty index, discrimination index, item-total correlation, and known group technique for validity were performed. An exploratory factor analysis was performed to test the construct validity of the instrument and its unidimensionality. The results reveal that a two-factor structure was appropriate for the Korean school-age health literacy tool (root mean square error of approximation = 0.06, Comparative Fit Index = 0.96, and Tucker-Lewis Index = 0.95). From the remaining 16 items, the internal consistency reliability coefficient of this instrument was 0.85, and the criterion-related validity was 0.62 (p < 0.001). The Korean health literacy instrument for late school-aged children was suitable for screening individuals who have limited health literacy. Based on the findings of this study, future studies must continue to conduct empirical investigations on the Korean health literacy instrument for late school-aged children.

Health Literacy Levels among Italian Students: Monitoring and Promotion at School

Health literacy was identified as an important determinant of health, particularly for adolescents. However, more efforts are needed to monitor this construct and provide inputs for policy development. This study aims to: (a) Assess the validity and reliability of the Italian version of the Health Literacy for School-Aged Children (HLSAC-I); (b) Identify the health literacy levels among Italian students and compare them with other countries’ levels; and (c) Identify the associations between health literacy and multiple social determinants (social stratifiers, family, and school connectedness). Data came from the Health Behaviour School-Aged Children survey, carried out in the Lombardy region in northern Italy in 2018. A representative sample of 2,287 13- and 15-year-old Lombardian students was involved. The results support the validity and reliability of the HLSAC-I. A total of 18.7% of the sample reported low levels, and only 6.8% reported high levels. Italian students reported the lowest levels of health literacy compared with other countries. School connectedness and educational approach are the most relevant associated factors. This study confirms a school’s role in reducing inequalities and promoting health. It highlights the importance of monitoring health literacy and implementing health promotion policies at school through a whole-school approach.

Food Literacy Interventions in Elementary Schools: A Systematic Scoping Review

BACKGROUND

Childhood is a critical period for developing food-related skills and knowledge, known as food literacy (FL). Schools may be an important setting for interventions aiming to improve FL in children. This systematic scoping review aimed to characterize food literacy interventions in elementary schools.

METHODS

Databases (PubMed, Web of Science, and EBSCO) were searched for FL interventions in elementary schools (students aged 4-12 years). Studies were assessed according to design, duration, theoretical underpinning, and ascertainment of FL outcome(s). Interventions were assessed according to FL competencies (functional, interactive, and critical).

RESULTS

After exclusions, 116 studies were eligible for review, including 105 original interventions. Interventions ranged from 45 minutes to 4 years. Social cognitive theory was the most referenced theory and common interventions included; classroom lessons, games, school gardens, food preparation, and cooking classes. Most studies measured FL outcomes quantitatively (96%, N = 111). All studies addressed functional FL (N = 116), while 77% (N = 89) addressed interactive FL and 28% (N = 32) addressed critical FL.

CONCLUSIONS

This first international review of FL programs in elementary schools found great heterogeneity in school-based FL intervention design and measurement of FL. Few interventions addressed critical FL, which should be a focus for future interventions.

Adapting the European Health Literacy Survey Questionnaire for Fourth-Grade Students in Germany: Validation and Psychometric Analysis

BACKGROUND

Until now, children younger than age 13 years have received little attention in research on health literacy. Although some tools assess children's health literacy, no validated tool is available that assesses self-reported health literacy in a systematic and comparable way. The European Health Literacy Survey Questionnaire (HLS-EU-Q) is a valid and reliable measure of adults' self-reported health literacy. It has also been used among adolescents, but it has never been adapted for use with children. We believe it would be worth adapting for younger age groups so that self-reported health literacy could be assessed continuously.

OBJECTIVE

This study aimed to quantitatively test an adapted scale based on the HLS-EU-Q developed for German-speaking children age 9 and 10 years.

METHODS

An adapted 26-item HLS-EU-Q scale was given in a paper-and-pencil survey to 907 fourth-grade students in North Rhine-Westphalia, Germany. The psychometric properties of the scale were investigated with item analysis and factor analyses, and both convergent and discriminant validity were assessed.

KEY RESULTS

Of the 26 tested items, 9 were discarded due to poor performance in terms of missing values, item difficulty, and factor structure. This left a 15-item scale with a high internal consistency (α = .791) that takes only a short time to administer. The scale, called the HLS-Child-Q15, had a low correlation with functional health literacy (r = .107, p < .001), and a moderate correlation with indicators of self-efficacy (ρ = .280 to .306, p < .001). The latter indicates adequate discriminant validity, whereas the former points to a need to further investigate convergent validity.

CONCLUSIONS

This is the first study to apply an age-adapted version of the HLS-EU-Q to children. Statistical analyses indicated the successful development of a promising instrument, but further research is needed on its factor structure and validity. This study contributes significantly to the comparative assessment of health literacy across the life course by providing a measurement tool for children age 9 and 10 years. [HLRP: Health Literacy Research and Practice. 2020;4(3):e144-e159.] PLAIN LANGUAGE SUMMARY: The European Health Literacy Survey Questionnaire was adapted for German-speaking 9- and 10-year-old children, and 26 adapted items were tested in a written survey of 907 children. Item analysis resulted in a 15-item scale with satisfactory psychometric properties. This scale, the HLS-Child-Q15, shows high internal consistency and can be used to assess self-reported health literacy in German-speaking 9- and 10-year-old children. Nonetheless, further studies are needed to validate these results.

Addressing Health Literacy in Schools in Germany: Concept Analysis of the Mandatory Digital and Media Literacy School Curriculum

It is generally agreed upon that the development of health literacy should be addressed from an early age onwards in order to empower children to develop their full health potential. Schools can be seen as an ideal venue for strengthening health literacy because they reach almost all school-aged children throughout their school years. The development of health literacy at a young age is a catalyst for healthy development throughout across the life span. Evidence shows that health and education are intertwined with favorable effects for health (e.g., health behavior, knowledge) and education outcomes (e.g., academic achievement). However, health literacy is often not sufficiently integrated into the school curriculum despite its importance to health and education. Integrating health literacy into schools is challenging, as both schools and teachers already face numerous educational requirements that may prevent them from addressing health in the classroom because they perceive it as an additional task. This is why taking a sensitive approach is important, adapted to the needs of schools and highlighting the benefits of health literacy. Installing health literacy in schools succeeds more easily if it can be linked to existing curricular requirements. In this context, curriculum and instruction on media literacy, information literacy, and digital literacy are most promising subjects to include health literacy because these concepts share many commonalities with health literacy and often are already part of the school curriculum. The aim of this article is to (1) analyze a mandatory curriculum on media literacy in the state of North-Rhine-Westphalia in Germany, (2) highlight its intersections with health literacy, and (3) show how it can be used to address health literacy. The state media literacy framework is based on the federal standards for “digital education” developed by the German Conference on Education Ministries und Cultural Affairs (KMK). As education policy and practice is decentralized with sixteen federal states in Germany, each of them has got their own media literacy framework, or they are currently developing it. This curriculum analysis may serve as a methodological blueprint for educationalists, teachers, and policy-maker elsewhere in order to include health literacy into existing curricula both health and non-health. It may help to integrate health literacy into schools when combined with existing curricula.

Health literacy for children and families

The relationship between reading ability and health, known as health literacy, broadly reflects the skills and competencies required to operate within the healthcare environment. It is only recently that we have seen attempts to conceptualize health literacy in the context of medication use by using terms such as medication literacy. Health literacy changes over one's lifetime and is dependent on factors such as numeracy, education, income, gender and country. Low health literacy and low medication literacy have been identified as significant risk factors for poor health outcomes of adults and children. With an evaluation of common tools used to assess health literacy and medication literacy, the aim of this review is to describe the shared responsibility between patients and healthcare providers for the communication of health and medication information. Key strategies and interventions to improve two-way communication between patients and healthcare providers are highlighted, with a focus on how health literacy can impact child health outcomes.

Objective health literacy skills among ninth graders in Finland: outcomes from a national learning assessment

Background:

Health literacy (HL) is an important determinant for maintaining and improving health throughout the lifespan. This underlines the need to monitor HL, including among adolescents, and to understand the factors explaining HL, with a view to decreasing differences in HL. The aim of this study was to objectively measure HL, and the relationship between HL and socio-demographic factors (gender, language of instruction, pupils’ educational aspirations, parents’ educational background and pupils’ school achievement) among pupils (n = 3652) at the end of basic education in Finland.

Methods:

A nationally representative assessment, which included 55 items on HL, was conducted as a traditional paper-and-pencil test in schools. The data were analysed via descriptive statistics and a two-level hierarchical linear model to determine how the socio-demographic factors affected HL.

Results:

The pupils’ average score on the HL test items was 58.9%, indicating a satisfactory HL level. A two-level hierarchical linear model showed that the variables (gender, language of instruction, pupils’ educational aspirations, parents’ educational background and pupils’ school achievement) predicting the HL level had statistically significant effects.

Conclusions:

Among ninth graders (15–16 years old), almost one third of the boys and 8% of the girls exhibited an unsatisfactory HL level. The study also confirmed the importance of school-related factors in explaining HL differences. Since low HL has been linked to several unfavourable health indicators and has been viewed as an underestimated problem in times of pandemic and other health crises, the findings suggest that the HL level of Finnish ninth graders is a clear public-health issue.

Measuring and Exploring Children's Health Literacy in The Netherlands: Translation and Adaptation of the HLS-Child-Q15

As health literacy (HL) is hypothesized to develop throughout life, enhancement during childhood will improve HL and health during life. There are few valid, age-appropriate tools to assess children’s HL. The German-language European Health Literacy Survey Questionnaire Adapted for Children (HLS-Child-Q15-DE) is a self-report questionnaire adapted from the adult European Health Literacy Survey Questionnaire. This study aims to translate the HLS-Child-Q15 to Dutch and explore the sample’s HL distribution. The HLS-Child-Q15-DE was translated following WHO guidelines and administered digitally to 209 Dutch schoolchildren (eight-to-eleven-year-olds). Its psychometric properties were assessed and the sample’s HL distribution was explored by demographic characteristics. The HLS-Child-Q15-NL had high internal consistency (α = 0.860) and moderate to strong item-total correlations (mean = 0.499). For 6 of the 15 items, >10% of participants answered “do not know”, indicating comprehension problems. Higher HL scores were observed for ten-to-eleven-year-olds (compared with eight-to-nine-year-olds; p = 0.021) and fourth-grade students (compared with third-grade; p = 0.019). This supports the idea that HL evolves throughout life and the importance of schools in this process. With the HLS-Child-Q15-NL, a Dutch measurement instrument of children’s HL is available, although it needs further tailoring to the target group. More research is needed to decrease comprehension problems and to investigate retest reliability and construct validity.

Die Nutzung von Modellen und Theorien unterstützt die Evidenzbasierung. Über die Evidenzentwicklung hinaus legen alle Verbünde einen Schwerpunkt auf die zumindest exemplarische Implementierung des neuen Wissens.

Durch die Methodenvielfalt kann eine breit gefächerte Evidenzbasierung unter Berücksichtigung verbundspezifischer Aspekte realisiert werden. Grenzen für eine weitere systematische Stärkung der Evidenzbasierung liegen in strukturellen Rahmenbedingungen. Insbesondere die Einbindung von nichtakademischen, zivilgesellschaftlichen Akteur*innen und Nutzer*innen für die Arbeit mit schwer erreichbaren Zielgruppen kann oft nicht ausfinanziert bzw. zeitlich berücksichtigt werden. Die COVID-19-Pandemie verdeutlicht die Wichtigkeit eines flexiblen Methodenspektrums, in dem ein sinnvolles Zusammenspiel von digitalen und analogen Methoden anzustreben ist.

What Role Does Body Image in Relationship between Level of Health Literacy and Symptoms of Eating Disorders in Adolescents?

(1) Background: The aim of this study was to explore the associations between health literacy and symptoms for eating disorders among adolescents, taking into consideration age and gender and whether this association is mediated by body image. (2) Methods: We used data on 5054 adolescents (mean age = 13.9, 51.7% boys) from the Health Behaviour in School-Aged Children study conducted in 2018 in Slovakia. We used logistic regression models to examine associations between level of health literacy and symptoms for eating disorders mediated by body image. (3) Results: Adolescents with low and medium levels of health literacy had a higher occurrence of reporting two or more symptoms of eating disorders (odds ratio (OR)/95% CI: 2.25/1.78-2.84 and 1.37/1.15-1.65). Adjustment for body image reduced the significance of association between low level of health literacy and symptoms for eating disorders by 26.4%, and association between medium level of health literacy and symptoms for eating disorders by 29.7%. (4) Conclusions: Adolescents who have a low health literacy level were found to have a higher probability of having symptoms for eating disorders, especially when they perceive themselves as fat. The study refers to potential theoretical frameworks for health literacy intervention that may provide guidelines for the intervention design and materials.

Functional Health Literacy: Psychometric Properties of the Newest Vital Sign for Portuguese Adolescents (NVS-PTeen)

Self-management of health requires skills to obtain, process, understand, and use health-related information. Assessment of adolescents’ functional health literacy requires valid, reliable, and low-burden tools. The main objective of this study was to adapt and study the psychometric properties of the Newest Vital Sign for the Portuguese adolescents’ population (NVS-PTeen). Classic psychometric indicators of reliability and validity were combined with item response theory (IRT) analyses in a cross-sectional survey, complemented with a 3-month test-retest assessment. The NVS-PTeen was self-administered to students enrolled in grades 8 to 12 (12 to 17 years old) in a school setting. Overall, 386 students (191 girls) from 16 classes of the same school participated in the study (mean age = 14.5; SD = 1.5). Internal reliability of the NVS-PTeen was α = 0.60. The NVS-PTeen total score was positively and significantly correlated with Portuguese (r = 0.28) and mathematics scores (r = 0.31), school years (r = 0.31), and age (r = 0.19). Similar to the original scale (for the U.S.), the NVS-PTeen is composed of two dimensions, reading-related literacy and numeracy. Temporal reliability is adequate, though with a learning effect. IRT analyses revealed differences in difficulty and discriminative capacity among items, all with adequate outfit and infit values. Results showed that the NVS-PTeen is valid and reliable, sensible to inter-individual educational differences, and adequate for regular screening of functional health literacy in adolescents.

Health literacy of college freshmen in jiangsu, China: A 3-year longitudinal survey

ABSTRACT

Health literacy (HL) has become an important public health issue and received growing attention in recent years. However, knowledge about the HL of adolescents and young adults is limited.[1] This study aimed to investigate the awareness rate of HL and its related factors among college freshmen in Jiangsu, China. And the results were used to support the promotion intervention to improve the HL of at-risk groups among this population.A total of 25,272 freshmen were surveyed through multi-stage stratified random sampling from 20 colleges and universities in Jiangsu province between 2016 to 2018. Data were obtained using the "Chinese Citizen Health Literacy Questionnaire" (2013 edition). Multiple logistic regression analysis was conducted to determine the factors influencing HL levels.The awareness rate of HL of college freshmen in Jiangsu province was 26.6% among the 25,272 subjects. The awareness rate of HL tended to increase from 2016 to 2018, which was 17.9%, 21.5%, and 39.6%, respectively (P < 0.001). Specifically, except for chronic diseases, knowledge and attitudes, knowledge and attitudes toward health-related behavior and lifestyle, health-related skill and scientific views of health, infection diseases, safety and first aid, medical care, health information awareness rate all have improved to a certain degree (P < .001). The independent factors associated with HL awareness rate were sex (odds ratio [OR] = 1.099, (1.039 -1.164)), residence (urban: OR = 1.141, (1.056∼1.234)), educational system (OR = 2.133, (1.975-2.305)), only child or not (OR = 1.087, (1.018-1.161)), family structure (OR = 1.192, (1.078-1.319)) and maternal education level (high school: OR = 1.183 (1.067-1.313); university and more: OR = 1.481 (1.324-1.658)).Awareness rate of HL of college freshmen is associated with multi-complex factors, further works are recommended to improve the HL levels of college freshmen, especially for the aspect of chronic diseases.

Promotion of Elementary School Students' Health Literacy

Health literacy is an important outcome of the discussion of school-related health education and health promotion in the 21st century. Although the improvement of health literacy at an early age is increasingly recognized and few interventions show the development of children´s health literacy, still there is little research in this area. The purpose of the study was to examine the enhancement of health literacy among children in a physical activity-based program at elementary school. In total, 137 students aged 6–12 years participated in the program, which included health knowledge transfer in child-appropriate games and exercises. Participants´ health literacy was assessed using the HLS-Child-Q15-DE at the beginning and the end of the program. The instrument measures the access, understanding, appraisal and application of health-related information on a four-point Likert-type scale. As expected, the Wilcoxon signed-rank test revealed significant increases in self-reported health literacy over time. The results show that the degree of change in health literacy was not associated with gender or age. The results suggest that the physical activity-based program has the potential to improve elementary school children´s health literacy, even though in a single group pilot study.

Dimensionen der Gesundheitskompetenz von Viertklässler*innen

Hintergrund

Die Gesundheitskompetenz (GK) junger Menschen wird von Wissenschaft und Politik zunehmend als Ansatzpunkt für Gesundheitsförderung und Prävention anerkannt. Gerade die GK von Kindern wurde jedoch, insbesondere in Deutschland, bisher kaum erforscht. Diese Studie widmet sich dieser Forschungslücke, indem sie die GK von Viertklässler*innen in Nordrhein-Westfalen (NRW) untersucht.

Ziel der Arbeit (Fragestellung)

Die Fragestellung ist die explorative Beschreibung verschiedener Dimensionen der GK von Kindern unter Berücksichtigung sozioökonomischer Merkmale.

Material und Methoden

Es wurde eine schriftliche Klassenraumbefragung durchgeführt. Der Fragebogen, der speziell für 9‑ bis 10-Jährige entwickelt wurde, umfasst drei Dimensionen der GK: selbstberichtete allgemeine GK, funktionale GK (schriftsprachliche und numerische Fähigkeiten) und das Gesundheitswissen.

Ergebnisse

Es wurden 899 Schüler*innen an 32 Schulen befragt. Hierbei wurde eine hohe selbstberichtete GK ermittelt: die Befragten empfinden den Umgang mit Gesundheitsinformationen als einfach. Kinder mit niedrigem Wohlstand schneiden in allen Dimensionen der GK signifikant schlechter ab. Dies gilt mit Ausnahme der selbstberichteten GK auch für Kinder, die zuhause nicht nur Deutsch sprechen.

Schlussfolgerung

Diese Studie untersucht erstmals die GK von Viertklässler*innen in NRW. Wenngleich die selbstberichtete GK hoch ist, zeigt sich schon bei dieser jungen Altersgruppe ein sozialer Gradient hinsichtlich Wohlstand und Sprache. Die Forschungslage ist für das Kindesalter zwar noch lückenhaft und es besteht weiterhin Forschungsbedarf, die Ergebnisse deuten aber auf einen frühen Interventionsbedarf hin, um allen Kindern unabhängig von ihrer Herkunft zu ermöglichen, GK in dem Maß zu entwickeln, wie es der eigenen Gesundheit zuträglich ist.

Subjective Generic Health Literacy and Its Associated Factors among Adolescents: Results of a Population-Based Online Survey in Germany

Profound data on adolescent health literacy are needed as a requirement for the development of health literacy promoting interventions. This paper aims to study the level of generic health literacy among adolescents and to explore associations between health literacy and socio-demographic (age, sex, family affluence, migration background), social (social support by family and friends) and personal (self-efficacy) factors. We conducted a representative cross-sectional online survey. Four health literacy dimensions were captured among 14–17 years old adolescents living in Germany (n = 1235) with the “Measurement of Health Literacy Among Adolescents-Questionnaire” (MOHLAA-Q). Descriptive, bivariate and multiple logistic regression analyses were used to analyse the data (n = 1202). We found poor health literacy levels—to varying degrees—in all examined health literacy dimensions: dealing with health-related information (8.41% with many difficulties), health-related communication skills (28.13% with low skills), attitudes toward one’s own health and health information (8.81% with passive attitudes) and health-related knowledge (22.73% with low levels). We identified significant associations between poor health literacy levels and all factors studied except for age. Our results indicate a need for the implementation of evidence-based health literacy-related promoting interventions, preferentially in education and training institutions.
