Optimal health literacy measurement for the clinical setting: A systematic review

Serial mediation roles of empowerment and self-care activities connecting health literacy, quality of life, and glycemic control in people with type 2 diabetes

BACKGROUND

Health literacy, empowerment, and self-care activities are likely the crucial concepts affecting the quality of life and glycemic control in people with type 2 diabetes (T2D). However, evidence demonstrating the mechanisms underlying these concepts is scarce.

AIMS

The aim of this study was to test the serial mediation roles of empowerment and self-care activities on the relationships between health literacy and quality of life and between health literacy and hemoglobin A1c (HbA1c) in people with T2D.

METHODS

A cross-sectional study was conducted among 319 people with T2D in Guangzhou, China, from July 2019 to January 2020. Data were collected using the Health Literacy Scale, the Diabetes Empowerment Scale-Short Form, the Summary of Diabetes Self-Care Activities Measure, and the Adjusted Diabetes-Specific Quality of Life Scale. RStudio 4.2.1 was used for serial mediation analysis.

RESULTS

The dimension of communicative health literacy accounted for the most total variance (β = 0.810, p < .001) in the construct of health literacy. The serial multiple mediation of empowerment and self-care activities in the associations between health literacy and quality of life (β = -.046, p = .019) and between health literacy and HbA1c (β = -.045, p = .005) were statistically significant.

LINKING EVIDENCE TO ACTION

This study emphasized the vital role of communicative health literacy when improving health literacy in people with T2D. Diabetes care and education specialists could implement empowerment approaches and flexible self-care strategies to improve the quality of life and glycemic control in people with T2D. Enhancing health literacy was suggested as a favorable strategy for promoting empowerment and self-care activities in people with T2D.

Health literacy, numeracy, graph literacy, and digital literacy: an overview of definitions, evaluation methods, and best practices

Health literacy is an important skill for people receiving care. Those with limited literacy face disparities in their care and health outcomes when strategies for addressing literacy are not used when delivering health information. In this article, we introduce the importance of considering health literacy, defining it and related concepts including numeracy, graph literacy, and digital literacy, and discuss open questions about measuring health literacy in clinical care. Finally, we present best practices, including assuming 'universal precautions', carefully considering wording, leveraging visualizations, recognizing cultural differences in interpretation, providing guidance on pilot testing, and considering digital literacy when developing electronic materials.

Assessment Tools for Measuring Health Literacy and Digital Health Literacy in a Hospital Setting: A Scoping Review

Assessment of (digital) health literacy in the hospital can raise staff awareness and facilitate tailored communication, leading to improved health outcomes. Assessment tools should ideally address multiple domains of health literacy, fit to the complex hospital context and have a short administration time, to enable routine assessment. This review aims to create an overview of tools for measuring (digital) health literacy in hospitals. A search in Scopus, PubMed, WoS and CINAHL, following PRISMA guidelines, generated 7252 hits; 251 studies were included in which 44 assessment tools were used. Most tools (57%) were self-reported and 27% reported an administration time of <5 min. Almost all tools addressed the domain 'understanding' (98%), followed by 'access' (52%), 'apply' (50%), 'appraise' (32%), 'numeracy' (18%), and 'digital' (18%). Only four tools were frequently used: the Newest Vital Sign (NVS), the Short Test of Functional Health Literacy for Adults ((S)TOFHLA), the Brief Health Literacy Screener (BHLS), and the Health Literacy Questionnaire (HLQ). While the NVS and BHLS have a low administration time, they cover only two domains. HLQ covers the most domains: access, understanding, appraise, and apply. None of these four most frequently used tools measured digital skills. This review can guide health professionals in choosing an instrument that is feasible in their daily practice, and measures the required domains.

Exploring the health literacy status of people with hearing impairment: a systematic review

BACKGROUND

People with hearing impairment have many problems with healthcare use, which is associated with health literacy. Research on health literacy is less focused on people with hearing impairments. This research aimed to explore the levels of health literacy in people with hearing impairment, find the barriers to health literacy, and summarize methods for improving health literacy.

METHODS

A systematic review was conducted using three databases (PubMed, Cochrane, and Embase) to search the relevant articles and analyze them. The studies were selected using pre-defined inclusion/exclusion criteria in two steps: first, selection by examining the title and abstract; and second, after reading the study in full. The Risk of Bias Assessment Tool for Nonrandomized Studies (RoBANS) was used to assess the quality of the articles.

RESULTS

Twenty-nine studies were synthesized qualitatively. Individuals with hearing impairment were found to have lower health literacy, when compared to those without impairment, which can lead to a higher medical cost. Most of the people with hearing impairment faced barriers to obtaining health-related information and found it difficult to communicate with healthcare providers. To improve their health literacy, it is essential to explore new ways of accessing health information and improving the relationship between patients and healthcare providers.

CONCLUSIONS

Our findings show that people with hearing impairment have lower health literacy than those without. This suggests that developing new technology and policies for people with hearing impairment is necessary not to mention promoting provision of information via sign language.

Rational Drug and Antibiotic Use Status, E-Health Literacy in Syrian Immigrants and Related Factors: A Cross-Sectional Study

Rational drug use is a pivotal concept linked with morbidity and mortality. Immigration plays a significant role as a determinant affecting individuals' health-related attitudes, behaviors, and the pursuit of health services. Within this context, the study was initiated to assess the factors influencing health literacy and rational drug use among Syrian immigrants in Istanbul. A cross-sectional study was undertaken on 542 Syrian adults utilizing a three-part questionnaire encompassing sociodemographics, rational drug use, and the e-health literacy scale (eHEALS). With an average age of 39.19 ± 13.10 years, a majority of participants believed medications should solely be doctor-prescribed (97%) and opposed keeping antibiotics at home (93.7%). Yet, 62.5% thought excessive herbal medicine use was harmless. The mean eHEALS score stood at 20.57 ± 7.26, and factors like age, marital status, income, and duration of stay in Turkey influenced e-health literacy. Associations were seen between low e-health literacy and being female, being older, having a lower education level, and regular medication use. Syrian immigrants displayed proper knowledge concerning antibiotics yet exhibited gaps in their understanding of general drug usage, treatment adherence, and herbal medicines. Approximately 80.3% had limited health literacy, pointing to the need for targeted interventions for enhanced health and societal assimilation.

Measuring skill-based health literacy in chronic airway disease patients: the development and psychometric evaluation of the Vancouver airways health literacy tool (VAHLT)

PURPOSE

This article describes the development of the Vancouver airways health literacy tool (VAHLT), a novel measure of skill-based health literacy specific to chronic airway diseases (CADs). Across several phases, psychometric characteristics of the VAHLT were examined and used to guide its development.

METHODS

An initial pool of 46 items was developed using input from patients, clinicians, researchers, and policy-makers. An initial patient sample (N = 532) was evaluated and used to inform item revisions. A revised 44-item pool was then evaluated using a second sample, the results of which aided in the selection of a final set of 30 items. The finalized 30-item VAHLT was then psychometrically evaluated using the second sample (N = 318). An item response theory approach was utilized to evaluate the VAHLT by assessing model fit, item parameter estimates, test and item information curves, and item characteristic curves. Reliability was assessed using ordinal coefficient alpha. We additionally assessed differential item functioning between asthma and COPD diagnoses.

RESULTS

The VAHLT demonstrated a unidimensional structure and reasonably discriminated patients in the lower range of health literacy estimates. The tool demonstrated strong reliability (α = .920). Two of the 30 items were found to exhibit non-negligible differential item functioning.

CONCLUSIONS

This study presents compelling evidence of validity in several areas for the VAHLT, including content and structural validity. Further external validation studies are needed and forthcoming. Overall, this work represents a strong first step towards a novel, skill-based, and disease-specific measure of CAD-related health literacy.

Testing a single item screener to support family doctors in identifying patients with limited health literacy: convergent validity of the SILS and the HLS-EU-Q16

BACKGROUND

Low health literacy (HL) is associated with reduced disease self-management skills, worse health outcomes, an increased number of hospitalizations, more frequent use of the emergency room and less utilization of preventive services. To support patients with low HL it is crucial to identify affected patients. HL is a multidimensional construct, which covers different skills and abilities to make informed health decisions. Validated brief screening tools to assess health-literacy-related skills or abilities in primary care settings are currently not available in German. This study aimed to validate a single item screener developed in the US for the German primary care setting.

METHODS

Our study used cross-sectional data from a survey among mainly chronically ill patients (n = 346) conducted in family practices in the state of North Rhine-Westphalia. We explored the convergent validity between a single item literacy screener (SILS) and the HLS-EU-Q16. The SILS measures functional HL by asking patients about their need for help when reading information materials. The HLS-EU-Q16 is a multidimensional HL measure frequently used for research purposes in Germany. Associations between the two instruments were examined using Spearman's correlations and regression analyses. The diagnostic performance of the SILS relative to the HLS-EU-Q16 was assessed using receiver operator curves (ROC).

RESULTS

The SILS had a statistically significant correlation with the HLS-EU-Q16 (Spearman ρ: 0.35) and explained 26% of its total variance. Stratified analyses of the convergent validity between both instruments by age, sex, migration background, education level and chronic disease status showed moderate statistically significant correlations in all subgroups (range: 0.223 to 0.428). With an area under the curve of 0.66, the receiver operator curve indicated a satisfactory diagnostic performance of the SILS relative to the HLS-EU-Q16.

CONCLUSIONS

The SILS provided an acceptable initial assessment of HL limitations among a heterogeneous population of mainly chronically ill patients in a primary care setting. With only one item, the SILS can be a short and effective tool for routine use in primary care and specialized care settings. Future research should test the SILS in other populations and pilot applications of the SILS in routine care.

Using machine learning to design a short test from a full-length test of functional health literacy in adults-The development of a short form of the Danish TOFHLA

INTRODUCTION

Patients are compelled to become more involved in shared decision making with healthcare professionals in the self-management of chronic disease and general adherence to treatment. Therefore, it is valuable to be able to identify patients with low functional health literacy so they can be given special instructions about the management of chronic disease and medications. However, time spent by both patients and clinicians is a concern when introducing a screening instrument in the clinical setting, which raises the need for short instruments for assessing health literacy that can be used by patients without the involvement of healthcare personnel. This paper describes the development of a short version of the full-length Danish TOFHLA (DS-TOFHLA) that is easily applicable in the clinical context and where the use does not require a trained interviewer.

MATERIALS AND METHODS

Data were collected as a part of a large-scale telehomecare project (TeleCare North), which was a randomized controlled trial that included 1225 patients with chronic obstructive pulmonary disease. The DS-TOFHLA was developed solely using an algorithm-based selection of variables and multiple linear regression. A multiple linear regression model was developed using an exhaustive search strategy.

RESULTS

The exhaustive search showed that the number of items in the full-length TOFHLA could be reduced from 17 numeracy items and 50 reading comprehension items to 20 reading comprehension items while maintaining a correlation of r = 0.90 between the scores from full-length and short versions. A generic model-based approach was developed, which is suitable for development of short versions of the TOFHLA in other languages, including the original American version.

CONCLUSIONS

This study demonstrated how a generic model-based approach could be applied in the development of a short version of the TOFHLA, thereby reducing the 67 items to 20 items in the short version. Furthermore, this study showed that the inclusion of numeracy items was not necessary. The development of the DS-TOFHLA presents an opportunity to reliably identify patients with inadequate functional health literacy in approximately 5 minutes without involvement of healthcare personnel. The approach may be used in the development of short versions of any scaling questionnaire.

Tools to Measure Health Literacy among Adult Hispanic Populations with Type 2 Diabetes Mellitus: A Review of the Literature

Health literacy (HL) is associated with short- and long-term health outcomes, and this is particularly relevant in Hispanics, who are disproportionally affected by lower HL. Hispanics have become the largest minority population in the United States. Also, Hispanics experience higher burdens of chronic diseases such as type 2 diabetes mellitus (T2DM) than non-Hispanic whites. Thus, effectively choosing culturally appropriate validated instruments that measure a marker found in health assessments should be a serious consideration. Using a systemized approach, we identified and reviewed 33 publications and found eight different HL and numeracy (separate or combined) instruments. We assessed the study designs and instrument structures to determine how HL was measured across these studies. We categorized the results into direct and indirect measurements of HL. The Test of Functional Health Literacy in Adults (TOFHLA) family of HL instruments was favored for direct measures of HL, while the Brief Health Literacy Screen (BHLS) instrument was favored for indirect measures. Despite identified trends in instruments used, more comprehensive measurement tools have been developed but not validated in Hispanic populations. In conclusion, further validation of more comprehensive HL instruments in adult Hispanic populations with T2DM could better assess HL levels and improve health promotion efforts.

A Systematic Review of Health Literacy Measurement Instruments in Portugal

<b><i>Introduction:</i></b> Health literacy evaluation is considered a priority issue in the health literacy research field. The complexity of the multiple definitions of health literacy and the diversity of instruments to evaluate health literacy has become a challenge to the establishment of comparisons across different studies. This work aimed to provide a systematic literature review of the existing measurement instruments adapted or developed for different groups of the Portuguese population. <b><i>Methods:</i></b> A comprehensive search of digital databases was conducted to systematize and understand the available knowledge about health literacy measurement in Portugal and to identify assessment tools and studies developed. The selection process was based on PRISMA guidelines. <b><i>Results:</i></b> A total of 17 publications were analysed regarding different aspects, which resulted in the identification of 11 different instruments, that were adapted or developed to measure health literacy in different groups of the Portuguese population, mainly adults, adolescents, and young adults. Seven instruments focusing on general health literacy (including e-health), 2 on mental health literacy, and the other 2 on oral health literacy were identified. <b><i>Discussion/Conclusion:</i></b> This study presents the first general overview of health literacy measurement in Portugal and clearly shows that to deepen our knowledge of health literacy in the Portuguese population it is essential to broaden the scope and the target of health literacy assessment to have a comprehensive understanding that will allow transforming our reality regarding health and disease.

Cultural and linguistic adaption and testing of the Health Literacy Questionnaire (HLQ) among healthy people in Korea

Backgrounds

This study administered the Health Literacy Questionnaire (HLQ) among Korean adults to examine its factor structure, reliability, and validity.

Methods

The HLQ items were translated and culturally adapted to the Korean context. The convenience sampling method was used, and data were collected. The difficulty level, confirmatory factor analysis (CFA) using diagonal weighted least squares (DWLS) estimator in R, discriminant validity, and composite reliability were performed.

Results

The easiest scale to obtain a high score was “Scale 4. Social support for health” and the hardest was “Scale 7. Navigating the healthcare system.” Nine one-factor models fitted well. The nine-factor structural equation model fitted the data well. All HLQ scales were homogenous, with composite reliability.

Conclusions

The Korean version of the HLQ has a strong construct and high composite reliability when applied to Korean adults.

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.

The right pick: Does a self-assessment measurement tool correctly identify health care consumers with inadequate health literacy?

OBJECTIVES

The aim of this study was to investigate whether a self-report measurement instrument (the Brief Health Literacy Screen, BHLS) correctly identifies healthcare consumers with inadequate health literacy. The yardstick for assessing the tool was the Newest Vital Sign (NVS).

METHODS

The study used baseline data from the Västerbotten Intervention Programme - VIsualiZation of Asymptomatic Atherosclerotic disease for Optimum Cardiovascular Prevention (VIPVIZA), a randomized controlled trial that is nested within the Västerbotten Intervention Program (VIP) in Sweden. Our analyses were computed on a subsample of 460 persons who underwent the measure of both health literacy scales. ROC analysis was used for the crucial computations.

RESULTS

The potential of the BHLS to identify healthcare consumers with inadequate health literacy remained unsatisfying for the complete sample, but reached an acceptable level for women and persons with only basic education.

CONCLUSIONS

The relationship is somewhat weaker than in comparable research in various other European countries. The differences might partly have been caused by the use of self-perception questions. Self-delusions, invariably a part of self-perception, may have affected the respective measure.

PRACTICE IMPLICATIONS

Caution is advised when patients' health literacy is assessed by only a few questions for self-report.

Health Literacy in Patients’ Clinical Records of Hospital Settings: A Systematic Review

Introduction

Health literacy (HL) can be defined as the individual's ability to understand and process health information. A low level of HL can be viewed as a stronger predictor of a person's health status than age, education level, and race. Although HL is an important determinant of health, it is often underestimated. This systematic review investigates the evidence on HL assessment in hospital settings.

Methods

PubMed Medline, CINAHL, Scopus, Web of Science and Educational Resources Information Centre databases were searched, with the date last searched being 16 March 2020. The PRISMA guidelines were applied, and the protocol of the study was registered with PROSPERO (CRD42021236029). The quality of the included studies was appraised using the STrengthening the Reporting of OBservational Studies in Epidemiology (STROBE) guidelines for cross-sectional studies.

Results

Five studies reported HL assessments in hospital patients’ clinical records. Four main strategies were used to implement HL routine assessment in hospitals: multidisciplinary teams, stakeholders, training, and monitoring. Different performance measures were used to monitor the feasibility of incorporating HL assessment into electronic health records (EHRs).

Conclusion

This review examined how inpatients’ HL is recorded in hospital settings. HL is poorly measured in a hospital setting. These results guide hospital leadership in involving nurses in HL assessment implementation in hospitals and support nurses in creating a specific performance measure dashboard to monitor effective HL assessments in hospitals.

Health Literacy and Clinical Outcomes Following Hematopoietic Stem-Cell Transplantation

PURPOSE:

To test associations between health literacy and clinical outcomes in patients undergoing hematopoietic stem-cell transplantation (HSCT).

METHODS:

English- and Spanish-speaking patients age ≥ 18 years were recruited while admitted for first allogeneic HSCT. Associations between low health literacy (Newest Vital Sign ≤ 3 or Short Test of Functional Health Literacy in Adults ≤ 22) and HSCT outcomes were evaluated.

RESULTS:

Twenty-eight percent of 177 participants had low health literacy by Newest Vital Sign. None had low health literacy by Short Test of Functional Health Literacy in Adults. There was no statistically significant difference between patients with low and adequate health literacy in hospital readmissions (60% v 54%, P = .4), 2-year overall survival (58% v 66%, P = .19), 2-year cumulative incidence of nonrelapse death (16% v 10%, P = .35), and acute graft-versus-host disease (53% v 44%, P = .3). In multivariable analyses, there were no significant associations between health literacy and clinical outcomes.

CONCLUSION:

In this cohort of patients undergoing HSCT, we did not identify a relationship between health literacy and clinical outcomes. Although we did not find statistically significant associations between health literacy and HSCT outcomes, interventions to address health literacy should be considered, given complex outpatient care and evidence for adverse outcomes associated with health literacy in similar diseases.

Croatian Version of the Short Assessment of Health Literacy for Spanish Adults (SAHLSA-50): Cross-Cultural Adaptation and Psychometric Evaluation

(1) Background: Short Assessment of Health Literacy for Spanish Adults (SAHLSA-50) was originally designed for Spanish-speaking regions, and translations validated for several languages. The aim of the study was to adapt and verify the psychometric characteristics of SAHLSA-50 in the Croatian context; (2) Methods: The cross-sectional study included 590 respondents from the general population older than 18 years of age. Health literacy was measured by two scales: SAHLCA-50 and the Croatian version of the Newest Vital Sign screening test (NVS-HR), which was used as a measure of concurrent validity. Subjective Health Complaints (SHC) and Satisfaction with Life Scale (SWLS) questionnaires were also used to assess convergent validity; (3) Results: Internal consistency reliability of SAHLCA-50 was high and corresponds to the findings of the authors of the original research. The Cronbach alpha coefficient for SAHLCA-50 version was 0.91. The correlation of SAHLCA-50 with the NVS-HR test speaks in favor of concurrent validity. Correlation between health literacy and SHC speaks for convergent validity, just as was expected, while correlation with life satisfaction was not observed; (4) Conclusions: The SAHLCA-50 test can be a good and quick tool to assess health literacy of the adult population in the Croatian language. HL can affect the health and quality of life of the individual and the wider community.

Health literacy in asthma and chronic obstructive pulmonary disease (COPD) care: a narrative review and future directions

Respiratory self-care places considerable demands on patients with chronic airways disease (AD), as they must obtain, understand and apply information required to follow their complex treatment plans. If clinical and lifestyle information overwhelms patients' HL capacities, it reduces their ability to self-manage. This review outlines important societal, individual, and healthcare system factors that influence disease management and outcomes among patients with asthma and chronic obstructive pulmonary disease (COPD)-the two most common ADs. For this review, we undertook a comprehensive literature search, conducted reference list searches from prior HL-related publications, and added insights from international researchers and scientists with an interest in HL. We identified methodological limitations in currently available HL measurement tools in respiratory care. We also summarized the issues contributing to low HL and system-level cultural incompetency that continue to be under-recognized in AD management and contribute to suboptimal patient outcomes. Given that impaired HL is not commonly recognized as an important factor in AD care, we propose a three-level patient-centered model (strategies) designed to integrate HL considerations, with the goal of enabling health systems to enhance service delivery to meet the needs of all AD patients.

Application of the eHealth Literacy Model in Digital Health Interventions: Scoping Review

BACKGROUND

Digital health interventions (DHIs) are increasingly being adopted globally to address various public health issues. DHIs can be categorized according to four main types of technology: mobile based, web based, telehealth, and electronic health records. In 2006, Norman and Skinner introduced the eHealth literacy model, encompassing six domains of skills and abilities (basic, health, information, scientific, media, and computer) needed to effectively understand, process, and act on health-related information. Little is known about whether these domains are assessed or accounted for in DHIs.

OBJECTIVE

This study aims to explore how DHIs assess and evaluate the eHealth literacy model, describe which health conditions are addressed, and which technologies are used.

METHODS

We conducted a scoping review of the literature on DHIs, based on randomized controlled trial design and reporting the assessment of any domain of the eHealth literacy model. MEDLINE, CINAHL, Embase, and Cochrane Library were searched. A duplicate selection and data extraction process was performed; we charted the results according to the country of origin, health condition, technology used, and eHealth literacy domain.

RESULTS

We identified 131 unique DHIs conducted in 26 different countries between 2001 and 2020. Most DHIs were conducted in English-speaking countries (n=81, 61.8%), delivered via the web (n=68, 51.9%), and addressed issues related to noncommunicable diseases (n=57, 43.5%) or mental health (n=26, 19.8%). None of the interventions assessed all six domains of the eHealth literacy model. Most studies focused on the domain of health literacy (n=96, 73.2%), followed by digital (n=19, 14.5%), basic and media (n=4, 3%), and information and scientific literacy (n=1, 0.7%). Of the 131 studies, 7 (5.3%) studies covered both health and digital literacy.

CONCLUSIONS

Although many selected DHIs assessed health or digital literacy, no studies comprehensively evaluated all domains of the eHealth literacy model; this evidence might be overlooking important factors that can mediate or moderate the effects of these interventions. Future DHIs should comprehensively assess the eHealth literacy model while developing or evaluating interventions to understand how and why interventions can be effective.

Wellbeing Literacy: Conceptualization, Measurement, and Preliminary Empirical Findings from Students, Parents and School Staff

Aims: Wellbeing literacy is the intentional use of wellbeing relevant vocabulary, knowledge and language skills to maintain or improve the wellbeing of oneself, others and the world. In this study, we operationalize the human aspects of the concept of wellbeing literacy and empirically test its relationship with wellbeing and illbeing. We also assess its incremental variance in wellbeing and illbeing, after controlling for existing and well-established predictors of these constructs within education settings. Methods: We developed and empirically tested the Wellbeing literacy 6-item (Well-Lit 6) scale to assess the concept of wellbeing literacy in the education context. The scale was developed based on a working definition of wellbeing literacy, in combination with the Australian Curriculum, Assessment and Reporting Authority (ACARA)’s definition of literacy. The Well-Lit 6 was administered via a cross-sectional survey to three Australian samples that comprise different elements of Australian education systems: students (N = 1392), parents (N = 584) and school staff (N = 317). Results: Exploratory factor analysis (EFA) suggested the six items of the Well-Lit 6 form an independent construct, empirically distinguishable from other wellbeing-related constructs (e.g., general wellbeing, resilience, and emotion regulation). Convergent analyses showed wellbeing literacy was positively related to wellbeing and negatively related to illbeing. Incremental validity analyses showed wellbeing literacy predicted variance in wellbeing and illbeing after controlling for participant demographics, resilience, and emotion regulation, showing initial evidence of incremental validity. Conclusions: Our results provide preliminary evidence that wellbeing literacy is a distinct construct from wellbeing and illbeing, and it also demonstrates significant unique variance in these constructs over and above resilience and emotion regulation. The Well-Lit 6 is a useful provisional measure of wellbeing literacy, although we suggest a fruitful avenue for future research is to develop a more comprehensive scale of wellbeing literacy that denotes specific facets of communication, allowing a fuller exploration wellbeing literacy, its components, and their antecedents and consequences. We offer further recommendations for future research and discuss limitations with our approach.

Health Literacy for Cardiac Rehabilitation: An Examination of Associated Illness Perceptions, Self-Efficacy, Motivation and Physical Activity

Following a diagnosis of cardiovascular disease there is a need for patients to self-manage. Health literacy has been shown to be lower in patients with cardiovascular disease, yet research into health literacy in this population is limited. This study used the Health Literacy Questionnaire (HLQ) to examine the health literacy and associated health, health behaviours and psychological profiles of cardiac rehabilitation patients from a remote and rural regional programme in the Scottish Highlands. Consecutive patients referred to the service in a calendar year were sent a cross-sectional questionnaire by post. Hierarchical cluster analysis grouped respondents based on their health literacy profile, and nonparametric methods were used to analyse differences between clusters on the other measures. A total of 282 participants responded (45.7%). Respondents were older (median: 71 years) and more likely to be from more affluent areas. Five health literacy clusters emerged with different profiles of health, physical activity, self-efficacy, motivation and illness perceptions. There was no difference in relation to cardiac rehabilitation attendance by health literacy cluster, but those with lower health literacy were less likely to be aware of the referral. Patterns of health literacy are associated with health, health behaviours and some psychological constructs. Knowledge of distinct cluster characteristics may help services better target interventions.

Investigating Health Literacy in Systemic Lupus Erythematosus: a Descriptive Review

PURPOSE OF REVIEW

Inadequate health literacy is common among American adults, but little is known about the impact of health literacy in rheumatic diseases. The purpose of this article is to review studies investigating health literacy and its association with clinical outcomes in systemic lupus erythematosus (SLE).

RECENT FINDINGS

Several validated health literacy measures have been examined in SLE patients. Low health literacy is associated with worse patient-reported outcomes and lower numeracy with higher disease activity. Two studies found no association of low health literacy with medication adherence. One randomized controlled trial tested a medication decision aid among patients with low health literacy. We found a paucity of studies exploring health literacy in SLE. Low health literacy is associated with worse patient-reported outcomes and limited numeracy with higher disease activity in SLE. Further studies are needed exploring the impact of low health literacy on clinical outcomes and the effectiveness of literacy-sensitive interventions.

The psychometric testing of the functional, communicative, and critical health literacy tool

OBJECTIVE

The purpose of this study is to assess the validity and reliability of the English version of the FCCHL tool in urban and rural, socioeconomically vulnerable or unstable, chronic comorbid adults in the United States.

METHODS

A cross-sectional study measuring both validity and reliability.

RESULTS

A total of 276 participants were recruited. Internal consistency was measured using Cronbach's alpha of α = 0.87. External reliability was measured by test-retest methodology. Construct validity was measured using Confirmatory Factor Analysis that showed good fit. Criterion validity was measured by comparing the mean scores of the FCCHL tool sub-scales. Concurrent validity was measured by comparison of means of the FCCHL tool and education level compared to the NVS and s-TOFHLA.

CONCLUSION

The results demonstrated that the FCCHL tools is measuring three different concepts. Overall, the FCCHL tool was seen to have good validity and reliability in the identified population.

PRACTICE IMPLICATIONS

The FCCHL tool is a 14-item, self-report health literacy tool measuring more than functional health literacy. The tool can be used in practice to improve not only functional health literacy, but also communicative and critical which is highly applicable.

Special Considerations Related to Race, Sex, Gender, and Socioeconomic Status in the Preoperative Evaluation: Part 1: Race, History of Incarceration, and Health Literacy

Patients anticipating surgery and anesthesia often need preoperative care to reduce risk and facilitate services on the day of surgery. Preparing patients often requires extensive evaluation and coordination of care. Vulnerable, marginalized, and disenfranchised populations have special concerns, limitations, and needs. These patients may have unidentified or poorly managed comorbidities. Underrepresented minorities and transgender patients may avoid or have limited access to health care. Homelessness, limited health literacy, and incarceration hinder perioperative optimization initiatives. Identifying patients who will benefit from additional resource allocation and knowledge of their special challenges is vital to reducing disparities in health and health care.

Health Literacy: From a Property of Individuals to One of Communities

Health literacy (HL) is increasingly hailed as a strategy to improve the control individuals have over their health. A central critic of HL intervention is its overemphasis on individual level factors, something recognised in the 2008 report of the Commission of Social Determinants of Health (SDoH) that recommended expanding the scope of HL to cover the SDoH. The objective of our study was to assess the extent to which recent progress on HL captures the need for collective action on the SDoH. We conducted a scoping review on PubMed looking for review papers published between 2013–2018 in English and French. Definitions of HL were analysed against two main dimensions (i.e., locus of change of HL strategies and foreseen outcome of HL improvements). Despite a number of authors calling for more research on HL interventions at the community level and an expansion of the definition to cover the SDoH, we found that the recommendation of the Commission has yet to be implemented. Even when the definitions include the capacities of individuals on distal determinants, both the locus of change and outcomes of HL improvement do not go beyond intra individual factors (knowledge, skills, etc.). It is noteworthy that communities were either framed as a setting outside of health care services or as an aggregate of individuals. We found no instance of HL intervention regarding communities as complex systems of actors sharing a common space and dynamic. We conclude by suggesting a new definition of HL and by drawing attention to the research gap in addressing the upstream SDoH through HL actions.

Drivers of ‘clinically unnecessary’ use of emergency and urgent care: the DEUCE mixed-methods study

Background

There is widespread concern about the pressure on emergency and urgent services in the UK, particularly emergency ambulances, emergency departments and same-day general practitioner appointments. A mismatch between supply and demand has led to interest in what can be termed ‘clinically unnecessary’ use of services. This is defined by the research team in this study as ‘patients attending services with problems that are classified as suitable for treatment by a lower urgency service or self-care’. This is a challenging issue to consider because patients may face difficulties when deciding the best action to take, and different staff may make different judgements about what constitutes a legitimate reason for service use.

Objectives

To identify the drivers of ‘clinically unnecessary’ use of emergency ambulances, emergency departments and same-day general practitioner appointments from patient and population perspectives.

Design

This was a sequential mixed-methods study with three components: a realist review; qualitative interviews (n = 48) and focus groups (n = 3) with patients considered ‘clinically unnecessary’ users of these services, focusing on parents of young children, young adults and people in areas of social deprivation; and a population survey (n = 2906) to explore attitudes towards seeking care for unexpected, non-life-threatening health problems and to identify the characteristics of someone with a tendency for ‘clinically unnecessary’ help-seeking.

Results

From the results of the three study components, we found that multiple, interacting drivers influenced individuals’ decision-making. Drivers could be grouped into symptom related, patient related and health service related. Symptom-related drivers were anxiety or need for reassurance, which were caused by uncertainty about the meaning or seriousness of symptoms; concern about the impact of symptoms on daily activities/functioning; and a need for immediate relief of intolerable symptoms, particularly pain. Patient-related drivers were reduced coping capacity as a result of illness, stress or limited resources; fear of consequences when responsible for another person’s health, particularly a child; and the influence of social networks. Health service-related drivers were perceptions or previous experiences of services, particularly the attractions of emergency departments; a lack of timely access to an appropriate general practitioner appointment; and compliance with health service staff’s advice.

Limitations

Difficulty recruiting patients who had used the ambulance service to the interviews and focus groups meant that we were not able to add as much as we had anticipated to the limited evidence base regarding this service.

Conclusions

Patients use emergency ambulances, emergency departments and same-day general practitioner appointments when they may not need the level of clinical care provided by these services for a multitude of inter-related reasons that sometimes differ by population subgroup. Some of these reasons relate to health services, in terms of difficulty accessing general practice leading to use of emergency departments, and to population-learnt behaviour concerning the positive attributes of emergency departments, rather than to patient characteristics. Social circumstances, such as complex and stressful lives, influence help-seeking for all three services. Demand may be ‘clinically unnecessary’ but completely understandable when service accessibility and patients’ social circumstances are considered.

Future work

There is a need to evaluate interventions, including changing service configuration, strengthening general practice and addressing the stressors that have an impact on people’s coping capacity. Different subgroups may require different interventions.

Patient preferences for visualization of longitudinal patient-reported outcomes data

OBJECTIVE

The study sought to design symptom reports of longitudinal patient-reported outcomes data that are understandable and meaningful to end users.

MATERIALS AND METHODS

We completed a 2-phase iterative design and evaluation process. In phase I, we developed symptom reports and refined them according to expert input. End users then completed a survey containing demographics, a measure of health literacy, and items to assess visualization preferences and comprehension of reports. We then collected participants' perspectives on reports through semistructured interviews and modified them accordingly. In phase II, refined reports were evaluated in a survey that included demographics, validated measures of health and graph literacy, and items to assess preferences and comprehension of reports. Surveys were administered using a think-aloud protocol.

RESULTS

Fifty-five English- and Spanish-speaking end users, 89.1% of whom had limited health literacy, participated. In phase I, experts recommended improvements and 20 end users evaluated reports. From the feedback received, we added emojis, changed date and font formats, and simplified the y-axis scale of reports. In phase II, 35 end users evaluated refined designs, of whom 94.3% preferred reports with emojis, the favorite being a bar graph combined with emojis, which also promoted comprehension. In both phases, participants literally interpreted reports and provided suggestions for future visualizations.

CONCLUSIONS

A bar graph combined with emojis was participants' preferred format and the one that promoted comprehension. Target end users must be included in visualization design to identify literal interpretations of images and ensure final products are meaningful.

Re-thinking health literacy: using a capabilities approach perspective towards realising social justice goals

Health literacy has gained popularity as a useful concept to promote and protect health. Even though health literacy research has been prolific it has also been fragmented, facing challenges in achieving its empowerment and social justice-related aims. Crucial limitations make the application of its principles to the health of vulnerable and underrepresented groups problematic, even though these groups are disproportionately affected by ill health. Efforts to refine and make the concept more relevant have tended to expand health literacy models and situate health literacy 'in context' to reflect environmental and social factors shaping health literacy. Context-related factors however, have not been consistently embedded in operationalisation and measurement efforts.This paper argues for health literacy to be re-conceptualised through a capabilities approach lens. It proposes that the capabilities approach can uniquely address the conceptual and methodological criticisms applied to health literacy, whilst encompassing its critical conceptual understandings of health. The advantage of this approach over and above other developments in health literacy theory and practice is its focus on both people's opportunities or freedoms to achieve desired health-related aims, and their ability to do so. It enables shifting the focus away from health literacy as individual skills and competencies and towards the enabling or inhibiting factors shaping health literacy. A participatory approach is seen as essential for realising this conceptual shift.

Development and Psychometric Evaluation of the Cancer Health Literacy Scale in Newly Diagnosed Cancer Patients

BACKGROUND

Health literacy (HL) influences a patient's comprehension and judgment of health-related information. A rigorous assessment tool is needed to screen for low HL in order to improve it.

OBJECTIVE

The aim of this study was to develop and validate the Cancer Health Literacy Scale (C-HLS).

METHODS

The framework of the C-HLS is based on the Levels of Prevention model. The scale items were developed according to Nutbeam's 3 constructs of HL. We employed several procedures to develop the C-HLS, including focus group interviews, item generation, the expert Delphi process, and face validity. Various types of analysis, including reliability and split-half reliability testing, confirmatory factor analysis, and criterion-related validity testing, were performed; receiver operating characteristic curve analysis was also performed to confirm sensitivity and specificity.

RESULTS

There were 33 items included in the C-HLS for validation; 360 newly diagnosed cancer patients completed the survey. The administration time is only 10 to 15 minutes. Results showed that C-HLS had good reliability, split-half reliability, and validity. All confirmatory factor analysis model fit indices reached acceptable thresholds. The receiver operating characteristic curve analyses suggested that the C-HLS had an adequate combination of sensitivity and specificity to distinguish between high and low HL.

CONCLUSIONS

The C-HLS is a reliable, valid tool capable of discriminating levels of HL in the assessment of cancer patients and does not have an excessive administration time.

IMPLICATIONS FOR PRACTICE

This scale can aid our understanding of HL in newly diagnosed cancer patients and can serve as a basis for providing individual care interventions.

Associations of Acculturation with English- and Spanish-Language Health Literacy Among Bilingual Latino Adults

Background:

Low health literacy (HL) is associated with poor health status and outcomes. Racial/ethnic minorities in the United States disproportionately experience low HL and HL-related health disparities. Among Latinos, acculturation is associated with health outcomes, but little is known about the relationship between acculturation and HL.

Objective:

We examined associations of sociodemographic and acculturation variables with English- and Spanish-language HL among 142 bilingual Latino adults with adequate HL.

Methods:

HL was assessed in English using the Rapid Estimate of Adult Literacy in Medicine (REALM) and in Spanish with the Short Assessment of Health Literacy for Spanish-speaking Adults (SAHLSA). Acculturation was assessed using the four subscales of the Multidimensional Acculturation Scale-II. Associations of sociodemographic data and acculturation with HL were examined using linear regression.

Key Results:

Higher education, higher income, higher English proficiency, and lower Latino cultural identification predicted REALM scores (ps <.05) in univariate models. When these variables were entered into a single model, only education and Latino cultural identification were associated with REALM scores. In univariate analyses, the following characteristics were associated with SAHLSA scores: female gender, being partnered, higher education, higher income, being non-US born, lower English proficiency, and higher Spanish proficiency (ps < .05). Education, being non-US born, English proficiency, and Spanish proficiency were each significant in the multivariate model.

Conclusions:

Results revealed a significant association between acculturation and English- and Spanish-language HL among bilingual Latino adults with adequate HL, suggesting that HL should be assessed in the language in which individuals are most proficient. HL assessed in a nonprimary language may be confounded with language proficiency. [HLRP: Health Literacy Research and Practice. 2019;3(2):e81–e89.]

Plain Language Summary:

The results of this investigation revealed a significant association between acculturation and English- and Spanish-language health literacy among bilingual Latino adults. This suggests that health literacy should be assessed in the language in which individuals are most proficient. Health literacy assessed in a nonprimary language may be influenced by language proficiency.

QuikLitE, a Framework for Quick Literacy Evaluation in Medicine: Development and Validation

Background

A plethora of health literacy instruments was developed over the decades. They usually start with experts curating passages of text or word lists, followed by psychometric validation and revision based on test results obtained from a sample population. This process is costly and it is difficult to customize for new usage scenarios.

Objective

This study aimed to develop and evaluate a framework for dynamically creating test instruments that can provide a focused assessment of patients’ health literacy.

Methods

A health literacy framework and scoring method were extended from the vocabulary knowledge test to accommodate a wide range of item difficulties and various degrees of uncertainty in the participant’s answer. Web-based tests from Amazon Mechanical Turk users were used to assess reliability and validity.

Results

Parallel forms of our tests showed high reliability (correlation=.78; 95% CI 0.69-0.85). Validity measured as correlation with an electronic health record comprehension instrument was higher (.47-.61 among 3 groups) than 2 existing tools (Short Assessment of Health Literacy-English, .38-.43; Short Test of Functional Health Literacy in Adults, .34-.46). Our framework is able to distinguish higher literacy levels that are often not measured by other instruments. It is also flexible, allowing customizations to the test the designer’s focus on a particular interest in a subject matter or domain. The framework is among the fastest health literacy instrument to administer.

Conclusions

We proposed a valid and highly reliable framework to dynamically create health literacy instruments, alleviating the need to repeat a time-consuming process when a new use scenario arises. This framework can be customized to a specific need on demand and can measure skills beyond the basic level.

Defining loneliness in older adults: protocol for a systematic review

BACKGROUND

Socialization is an important part of the healthy aging process, but natural changes in the lifestyle and health of older people increased risk of loneliness. However, loneliness is not well defined and might differ in different cultures and settings. The main objective of this systematic review is to summarize literature on the topic and propose a definition that might help aging research and practice in the future.

METHODS

Eight databases including PubMed, Scopus, CINAHL, Web of Science, EMBASE, PsycINFO, Proquest, and Age Line bibliographic will be run individually to retrieve relevant literature on loneliness among elderly population using subject headings and appropriate MeSH terms. Inclusion and exclusion criteria will be developed and refined by the research team. Two reviewers will participate in each search stage including abstract/title and full text screening, data extraction, and appraisal. We will restrict our search to articles published in the English language biomedical journal between 2000 and 2017. The protocol adheres to the standards recommended by the PRISMA-P.

DISCUSSION

The results of this systematic review can present a more accurate definition of loneliness for researchers who aim at conducting new primary and secondary studies on this subject.

Measurement of health literacy in patients with cardiovascular diseases: A systematic review

BACKGROUND

While many instruments have been developed, validated, and used to assess health literacy skills, their use and appropriateness among patients with cardiovascular diseases (CVDs) are not widely studied.

OBJECTIVE

To identify, appraise, and synthesize available health literacy assessment instruments used in patients with CVDs.

METHODS

Electronic databases were searched for studies that used validated measures to assess health literacy in patients with CVDs. Included studies were assessed for risk of bias and the identified instruments were evaluated based on their psychometric properties. Data were synthesized using a narrative approach.

RESULTS

Forty-three studies were included in the review, of which 20 were cross-sectional studies and 12 were randomized controlled trials. Eleven health literacy assessment instruments were identified, of which only one was disease-specific. The Abbreviated version of the Test of Functional Health Literacy in Adults (S-TOFHLA) (n = 19) and the Rapid Estimate of Adult Literacy in Medicine (REALM) (n = 13) were found to be the most commonly used instruments to assess health literacy in CVDs.

CONCLUSIONS

The S-TOFHLA and the REALM are the most widely used instruments to evaluate health literacy in CVD population. More CVD-specific health literacy screening instruments are warranted. Assessment of health literacy should be a standard of care in patients with CVDs and effective interventions should be developed to improve the impact of limited health literacy on health outcomes in this population.

Resilience to climate-induced disasters and its overall impact on well-being in Southern Africa: a mixed-methods systematic review protocol

BACKGROUND

Southern Africa has long been vulnerable to climate-induced disasters, especially droughts and floods. The severity and frequency of disasters increased in the early 1980s, continuously eroding livelihoods, which in turn invoked humanitarian intervention. A systematic review of the relationship between resilience to drought and well-being will be undertaken.

METHODS

Studies will be included if they were conducted between January 1980 and December 2017; used quantitative and/or qualitative methods; were peer reviewed or comprise grey literature; covered Southern Africa; and measured resilience and its relationship to well-being. Data extraction will be informed by the Cochrane Public Health Group and the Joanna Briggs Institute manuals. The quality of evidence of the studies included will be assessed for risk bias, psychometric properties of tools used, and their suitability. The findings will be summarised into themes and narrated.

DISCUSSION

This protocol is guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines. The protocol gives insight of the scope and parameters for the systematic review to be carried out. The systematic review will establish how resilience to climate-induced disasters affects well-being. It will also provide recommendations to improve humanitarian coordination in Southern Africa.

SYSTEMATIC REVIEW REGISTRATION

The protocol was registered by the PROSPERO international prospective register of systematic reviews, reference CRD42017064396 .

Health Literacy Deficits Found Among Educated, Insured University Employees

Evidence has consistently shown that low/limited health literacy (HL) is associated with negative health consequences and higher costs for individuals and society. To generate internal data for employee training and health/wellness programming, an HL assessment of 120 university employees was conducted using the Newest Vital Sign (NVS), a valid and reliable clinical screening tool that asks individuals to interpret a nutrition label. Sociodemographic data were collected and time to administer the NVS tool was also measured. Even in this employed, well-educated sample (mean years of formal education was 16.6 years), 17% had scores indicating limited or possibly limited HL. Findings have implications for occupational training and health providers and programs. Even a well-educated workforce benefits from addressing HL challenges or situational issues with universal strategies. This project supports initiatives to assist employees better navigate, understand, and use health information and services to improve their health.

Limitations of the S-TOFHLA in measuring poor numeracy: a cross-sectional study

Background

Although the Short Test of Functional Health Literacy in Adults (S-TOFHLA) is widely used, misidentification of individuals with low health literacy (HL) in specific HL dimensions, like numeracy, is a concern. We examined the degree to which individuals scored as “adequate” HL on the S-TOFHLA would be considered as having low HL by two additional numerical measures.

Methods

English-speaking adults aged 45–75 years were recruited from a large, urban academic medical center and a community foodbank in the United States. Participants completed the S-TOFHLA, the Subjective Numeracy Scale (SNS), and the Graphical Literacy Measure (GL), an objective measure of a person’s ability to interpret numeric information presented graphically. Established cut-points or a median split classified participants and having high and low numeracy.

Results

Participants (n = 187), on average were: aged 58 years; 63% female; 70% Black/African American; and 45% had a high school degree or less. Of those who scored “adequate” on the S-TOFHLA, 50% scored low on the SNS and 40% scored low on GL. Correlation between the S-TOFHLA and the SNS Total was moderate (r = 0.22, n = 186, p = 0.01), while correlation between the S-TOFHLA and the GL Total was large (r = 0.53, n = 187, p ≤ 0.01).

Conclusions

Findings suggest that the S-TOFHLA may not capture an individuals’ HL in the dimension of numeracy. Efforts are needed to develop more encompassing and practical strategies for identifying those with low HL for use in research and clinical practice.

Short Assessment of Health Literacy (SAHL) in Portugal: development and validation of a self-administered tool

The goal of this study was to adapt, improve and validate a short, self-administered health literacy assessment tool for European Portuguese-speaking adults. Health literacy tools are of great importance to health authorities and professionals, as low or inadequate health literacy, that is, a limited capacity to handle health-related information, is associated with higher morbidity and mortality. The 18-item Short Assessment of Health Literacy for Brazilian Portuguese-speaking adults (SAHLPA-18) was adapted into European Portuguese. The European Portuguese tool (SAHLPA-23) includes five additional items. The SAHLPA-23 was tested in a convenience sample of 503 participants from two Portuguese regions. Socio-demographic data, literacy and cognitive indicators were collected. Participants also completed a questionnaire on comprehension of written health materials. Construct validity was assessed through correlations between SAHLPA-23 scores and education, literacy, and cognitive variables and score on the comprehension questionnaire. The psychometric properties of the new tool were compared with those of the SAHLPA-18. The mean SAHLPA-18 and SAHLPA-23 scores were 13.9 (77.2%; SD=2.9) and 18.3 (79.6%; SD=3.8), respectively. Both tools showed adequate reliability (Cronbach’s α>0.7). SAHLPA-23 was more highly correlated with all study variables than SAHLPA-18. Although both instruments displayed acceptable discriminative power, SAHLPA-23 had better accuracy than SAHLPA-18 (DeLong’s method: ΔAUC=0.09, Z=3.36; P<0.001). The SAHLPA-23 is an independent, feasible and innovative tool for estimation of health literacy in the Portuguese adult population.

Recognizing pharmaceutical illiteracy in community pharmacy: Agreement between a practice-based interview guide and questionnaire based assessment

BACKGROUND

Patients with limited pharmaceutical literacy are at increased risk of drug-related problems. Recognizing these patients in daily practice is difficult. The Recognition and Addressing of Limited Pharmaceutical Literacy (RALPH) interview guide was developed as practical set of questions to recognize patients with limited pharmaceutical literacy in daily pharmacy practice.

OBJECTIVE

To compare agreement between pharmaceutical literacy measured with the RALPH guide and a validated general health literacy questionnaire. In addition, we provide insight into patients' pharmaceutical literacy using the RALPH interview guide.

METHODS

Structured face-to-face interviews with patients who visited a community pharmacy to fill a prescription for themselves were conducted. The interview included the RALPH guide as well as the Functional Communicative Critical Health Literacy (FCCHL) questionnaire to measure general health literacy. Functional, communicative and critical skills were measured and agreement between two methods was calculated.

RESULTS

Data were collected from 508 patients. Patients with limited pharmaceutical literacy, indicated by the RALPH questions, also had a lower general health literacy level according to FCCHL scores. Agreement between the RALPH guide and FCCHL questionnaire was moderate (∼60%) for the three health literacy domains. Most patients (>90%) had correct understanding of frequency and timing of medication use, but 25% did not understand warnings or precautions correctly. Finding understandable information (39%), assessing information applicability (50%) and reliability (64%) were mentioned as difficult by patients.

CONCLUSION

Patients experienced difficulties with more complex skills, e.g. interpretation of warnings or precautions when using a medicine, finding and analyzing medication information. Whereas the FCCHL questionnaire is useful to assess general health literacy, the RALPH interview guide provides insight in the level of skills needed for good medication use and is more suitable for use in a medication specific context such as community pharmacy. Context specific assessment of skills is important to provide tailored pharmaceutical care.

O questionário apresenta boa sensibilidade, elevada fidelidade e boa validade interna e externa, podendo constituir-se como uma ferramenta de avaliação importante para a avaliação de necessidades de intervenção no domínio da literacia em saúde na população portuguesa.

A qualitative study of the experience of lower extremity wounds and amputations among people with diabetes in Philadelphia

The purpose of this study was to explore perceptions among people with type 2 diabetes about foot ulcers and lower extremity amputations. This was a qualitative observational study utilizing open-ended, semistructured interviews of 39 people with diabetes who were purposively selected because they had either a foot ulcer (n = 19) or a lower extremity amputation (n = 20). Interviews were audio-recorded, deidentified, and entered into NVivo 10.0 for coding and analysis. Our integrated analytic approach combined inductively and deductively derived codes that were applied to all transcripts. Coded data were summarized and examined for patterns. Participants' description of the relationship between diabetes and their foot ulcer or amputation revealed a limited understanding of the disease process. Disruption and loss of independence was expressed whether the person had a foot ulcer or an amputation. Treatment recommendations for foot ulcers were viewed by most as extremely difficult. Amputation was a feared outcome, but some learned to adapt and, at times felt that the amputation enhanced their quality of life. Clinicians have assumed that a focus on limb salvage is preferred over a major amputation. However, because of the complexity of care requiring frequent healthcare provider visits, the frequency of care failure, the frequency of recurrence, and mortality associated with having had a foot ulcer, it may be more appropriate for clinicians to prioritize quality-of-life salvage. Foot ulcer treatment failure may be due to a lack of providers' understanding of the impact of treatment on a patient's life.

Capturing health literacy assessment in the electronic health record through evidence-based concept creation: A review of the literature and recommendations for action

Health literacy is the capacity to understand and act upon health-related information and navigate the healthcare system. Published evidence demonstrates a relationship between health literacy and health status. Because of this, there are increasingly calls for a health literacy assessment to be collected and stored in the electronic health record for use by the healthcare team. This article describes the results of a literature review of health literacy assessment instruments with the goal of formulating semantically interoperable concepts that may be used to store the interpretation of the health literacy assessment in the electronic health record. The majority of health literacy instruments could be stored in the electronic health record using a three-concept solution of inadequate, marginal and adequate health literacy. This three-concept solution fully supports semantic interoperability needs across the patient care spectrum.

Does acculturation narrow the health literacy gap between immigrants and non-immigrants-An explorative study

OBJECTIVES

To compare functional health literacy (HL) levels in three immigrant groups to those of the German- and Italian-speaking non-immigrant population in Switzerland. Moreover, to investigate whether language-independent, respectively language-dependent, functional HL and variables of acculturation were associated with self-reported health status among immigrants.

METHODS

Language-independent HL was assessed with the Short Test of Functional Health Literacy (S-TOFHLA) in the respective native languages. Language-dependent HL was measured using Brief Health Literacy Screeners (BHLS) asking about participants' confidence in understanding medical information in the language of the host country. Measures of acculturation included length of stay and age when taking residency in Switzerland.

RESULTS

In particular Albanian- and Portuguese-speaking immigrants had lower levels of functional HL. In unadjusted analysis "age when taking residency in Switzerland" was associated with the BHLS. Adjusted analysis showed that the BHLS were significantly associated with self-reported health among all immigrant groups (p≤0.01).

CONCLUSIONS

Functional HL that is dependent on understanding of medical information in the language of the new host country is a better predictor for self-reported health status among immigrants than language-independent HL.

PRACTICE IMPLICATIONS

In the clinical setting limited functional HL might be a significant obstacle to successful disease treatment and prevention in immigrants.

What role does health literacy play in patients' involvement in medical decision-making?

Patients vary in their preferences towards involvement in medical decision-making. Previous research, however, gives no clear explanation for this observed variation in their involvement. One possible explanation might be health literacy. Health literacy refers to personal characteristics and social resources needed for people to access, understand and use information to make decisions about their health. This study aimed to examine the relationship between health literacy and self-reported patient involvement. With respect to health literacy, we focused on those competences relevant for medical decision-making. We hypothesized that people with higher health literacy report that they are more involved in medical decision-making. A structured questionnaire was sent to members of the Dutch Health Care Consumer Panel in May 2015 (response 46%, N = 974). Health literacy was measured using five scales of the Health Literacy Questionnaire. A regression model was used to estimate the relationship between health literacy and self-reported involvement. In general, our results did not show a relationship between health literacy and self-reported involvement. We did find a positive significant association between the health literacy scale appraisal of health information and self-reported involvement. Our hypothesis was partly confirmed. The results from this study suggest that higher order competences, that is to say critical health literacy, in particular, are important in reporting involvement in medical decision-making. Future research is recommended to unravel further the relationship between health literacy and patient involvement in order to gain insight into whether health literacy might be an asset to enhance patient participation in medical decision-making.

Measuring attributes of health literate health care organizations from the patients' perspective: Development and validation of a questionnaire to assess health literacy-sensitive communication (HL-COM)

BACKGROUND

Studies addressing the organizational contexts of care that may help increase the patients' ability to cope with a disease and to navigate through the health care system are still rare. Especially instruments allowing the assessment of such organizational efforts from the patients' perspective are missing. The aim of our study was to develop a survey instrument assessing organizational health literacy (HL) from the patients' perspective, i. e., health care organizations' responsiveness to patients' individual needs.

METHODS

A pool of 30 items was developed by a group of experts based on a literature review. The items were developed, tested and prioritized according to their importance in 11 semi-structured interviews and cognitive think-aloud interviews with cancer patients. The resulting 16 items were rated in a standardized postal survey involving a total of N=453 colon and breast cancer patients treated in cancer centers in Germany. An exploratory factor analysis, a confirmatory factor analysis and structural equation modelling were conducted. Item properties were analyzed.

RESULTS

83.2 % of the patients were diagnosed with breast cancer, 16.8 % had a diagnosis of colon cancer. The patients' mean age was 61 (26-88), 89.4 % were female. The most common comorbidities were hypertension (34.0 %) and cardiovascular disease (11.0 %). The final prediction model included nine items measuring the degree of health literacy-sensitivity of communication. The model showed an acceptable model fit. The nine items showed corrected item-total correlations between .622 and .762 and item difficulties between 0.77 and 0.87. Cronbach's α was .912.

DISCUSSION

In a comprehensive development process, the original item pool comprising several aspects of organizational HL was reduced to a one-dimensional scale. The instrument measures an important aspect of organizational HL; i.e., the degree of health literacy-sensitivity of communication (HL-COM). HL-COM was found to impact patient enablement, mediated through the support by physicians. Future research will have to test these associations in the context of other diseases or institutions.

The impact of health literacy and life style risk factors on health-related quality of life of Australian patients

BACKGROUND

Limited evidence exists regarding the relationship between health literacy and health-related quality of life (HRQoL) in Australian patients from primary care. The objective of this study was to investigate the impact of health literacy on HRQoL in a large sample of patients without known vascular disease or diabetes and to examine whether the difference in HRQoL between low and high health literacy groups was clinically significant.

METHODS

This was a cross-sectional study of baseline data from a cluster randomised trial. The study included 739 patients from 30 general practices across four Australian states conducted in 2012 and 2013 using the standard Short Form Health Survey (SF-12) version 2. SF-12 physical component score (PCS-12) and mental component score (MCS-12) are derived using the standard US algorithm. Health literacy was measured using the Health Literacy Management Scale (HeLMS). Multilevel regression analysis (patients at level 1 and general practices at level 2) was applied to relate PCS-12 and MCS-12 to patient reported life style risk behaviours including health literacy and demographic factors.

RESULTS

Low health literacy patients were more likely to be smokers (12 % vs 6 %, P = 0.005), do insufficient physical activity (63 % vs 47 %, P < 0.001), be overweight (68 % vs 52 %, P < 0.001), and have lower physical health and lower mental health with large clinically significant effect sizes of 0.56 (B (regression coefficient) = -5.4, P < 0.001) and 0.78(B = -6.4, P < 0.001) respectively after adjustment for confounding factors. Patients with insufficient physical activity were likely to have a lower physical health score (effect size = 0.42, B = -3.1, P < 0.001) and lower mental health (effect size = 0.37, B = -2.6, P < 0.001). Being overweight tended to be related to a lower PCS-12 (effect size = 0.41, B = -1.8, P < 0.05). Less well-educated, unemployed and smoking patients with low health literacy reported worse physical health. Health literacy accounted for 45 and 70 % of the total between patient variance explained in PCS-12 and MCS-12 respectively.

CONCLUSIONS

Addressing health literacy related barriers to preventive care may help reduce some of the disparities in HRQoL. Recognising and tailoring health related communication to those with low health literacy may improve health outcomes including HRQoL in general practice.
