The health literacy management scale (HeLMS): a measure of an individual's capacity to seek, understand and use health information within the healthcare setting

Status and influential factors of health literacy in patients with ischemic stroke: A cross-sectional study

AIM

The purpose of this study was to investigate the health literacy level and influencing factors of patients with ischemic stroke.

DESIGN

A cross-sectional study was conducted.

METHODS

We used convenient sampling to recruit potential participants. Patients with ischemic stroke who were hospitalized in the Department of Neurology, West China Hospital, Sichuan University in China from January 2022 to May 2023 were selected as subjects to complete the questionnaire survey. We used the National Institute of Health Stroke Scale to assess the neurological impairment of patients and the Health Literacy Scale for Chronic Patients to assess the health literacy level of patients.

RESULTS

The overall health literacy level of ischemic stroke patients was high (99.13 ± 10.15). Age, education level, per capita monthly family income, living situations and National Institutes of Health Stroke Scale score were independent risk factors affecting the health literacy level of patients with ischemic stroke. Patients with a higher education level (β = 0.151, P = 0.006) and higher per capita monthly family income (β = 0.179, P = 0.001) had higher levels of health literacy. Patients who lived with their spouses (β = -0.117, P = 0.012) had higher health literacy. Patients at an older age (β = -0.151, P = 0.001) and patients with higher NIHSS scores (β = -0.450, P = 0.001) had lower health literacy levels.

CONCLUSIONS

Age, education level, family per capita monthly income, living situations and National Institute of Health Stroke Scale score were related to the health literacy level of patients with ischemic stroke. According to these associated factors, targeted health education should be developed to improve the health literacy of patients and health outcomes.

Health literacy in cancer care: A systematic review

PURPOSE

Health literacy (HL) is a set of knowledge and skills that enables individuals to interpret and act upon health information, which is essential for health equity. There is a growing body of evidence in the field of HL in cancer care but there is, to our knowledge, no systematic review that explores the association between sociodemographic factors and HL among patients with cancer. The aim of this study was therefore to conduct a systematic review of the existing literature that assesses HL levels and the relationship between HL and sociodemographic factors in an adult cancer population.

METHODS

This is a systematic review and its protocol was registered in PROSPERO (ID: CRD42021164071). The study was conducted in accordance with the PRISMA statement. The literature search, from December 2009 to September 2023, was made in six databases, AMED, CINAHL, Embase, MEDLINE, PsycINFO, and Web of Science Core Collection.

RESULTS

Fifteen studies were included in the review. The included studies used nine different measurement tools for assessing HL. In the included studies between 11.9 % and 86 % had limited HL. We identified a relationship between limited HL and annual income, education level, ethnicity, living in rural areas and multiple comorbidities.

CONCLUSION

The results indicate that limited HL is prevalent in the cancer population and should be acknowledge in everyday practice to meet health equity. Our awareness about sociodemographic factors and its association with HL, may enhance adherence to cancer treatment and quality of life, and lower physical and emotional distress.

Health literacy and self-management among middle-aged and young hypertensive patients: a parallel mediation effect of illness perception and self-efficacy

Background

Hypertension is increasingly prevalent among young and middle-aged populations in rural China, accompanied by suboptimal self-management. Given that this population forms the backbone of the labor force, enhancing their self-management capabilities is crucial for improving overall population health. Studies indicate that individuals with good health literacy are more likely to effectively manage their health.

Methods

Grounded in the health literacy skills framework, a model was constructed in this study to examine the impact of health literacy on self-management among young and middle-aged hypertensive patients in rural China. Meanwhile, the mediating roles of illness perception and self-efficacy were also verified. Using a multi-stage stratified random sampling method, 338 patients were recruited to participate in the study. Structural equation modeling was utilized to establish the relationship model, and bootstrap tests were carried out to examine the mediating effects.

Results

The average self-management score was 70.45 ± 11.36. Health literacy exhibited a positive correlation with self-management (standardized β = 0.372, p < 0.001). The mediating effects through illness perception and self-efficacy were 0.040 and 0.236, constituting 6.68 and 39.31% of the total effect, respectively.

Conclusion

Illness perception and self-efficacy serve as parallel mediators amid the association between health literacy and self-management. Implementing psychological counseling and health education is imperative for augmenting self-management competence and cultivating an adaptive coping mentality.

Usability of an Automated System for Real-Time Monitoring of Shared Decision-Making for Surgery: Mixed Methods Evaluation

BACKGROUND

Improving shared decision-making (SDM) for patients has become a health policy priority in many countries. Achieving high-quality SDM is particularly important for approximately 313 million surgical treatment decisions patients make globally every year. Large-scale monitoring of surgical patients' experience of SDM in real time is needed to identify the failings of SDM before surgery is performed. We developed a novel approach to automating real-time data collection using an electronic measurement system to address this. Examining usability will facilitate its optimization and wider implementation to inform interventions aimed at improving SDM.

OBJECTIVE

This study examined the usability of an electronic real-time measurement system to monitor surgical patients' experience of SDM. We aimed to evaluate the metrics and indicators relevant to system effectiveness, system efficiency, and user satisfaction.

METHODS

We performed a mixed methods usability evaluation using multiple participant cohorts. The measurement system was implemented in a large UK hospital to measure patients' experience of SDM electronically before surgery using 2 validated measures (CollaboRATE and SDM-Q-9). Quantitative data (collected between April 1 and December 31, 2021) provided measurement system metrics to assess system effectiveness and efficiency. We included adult patients booked for urgent and elective surgery across 7 specialties and excluded patients without the capacity to consent for medical procedures, those without access to an internet-enabled device, and those undergoing emergency or endoscopic procedures. Additional groups of service users (group 1: public members who had not engaged with the system; group 2: a subset of patients who completed the measurement system) completed user-testing sessions and semistructured interviews to assess system effectiveness and user satisfaction. We conducted quantitative data analysis using descriptive statistics and calculated the task completion rate and survey response rate (system effectiveness) as well as the task completion time, task efficiency, and relative efficiency (system efficiency). Qualitative thematic analysis identified indicators of and barriers to good usability (user satisfaction).

RESULTS

A total of 2254 completed surveys were returned to the measurement system. A total of 25 service users (group 1: n=9; group 2: n=16) participated in user-testing sessions and interviews. The task completion rate was high (169/171, 98.8%) and the survey response rate was good (2254/5794, 38.9%). The median task completion time was 3 (IQR 2-13) minutes, suggesting good system efficiency and effectiveness. The qualitative findings emphasized good user satisfaction. The identified themes suggested that the measurement system is acceptable, easy to use, and easy to access. Service users identified potential barriers and solutions to acceptability and ease of access.

CONCLUSIONS

A mixed methods evaluation of an electronic measurement system for automated, real-time monitoring of patients' experience of SDM showed that usability among patients was high. Future pilot work will optimize the system for wider implementation to ultimately inform intervention development to improve SDM.

Study protocol: Exploring the use of Family Health Histories in the African American community to reduce health disparities in Flint, Michigan

Background Health disparities are costly and preventable differences in disease progression that disproportionately affect minority communities such as African Americans. Practices to reduce health disparities can be rooted in prevention, particularly through screening tools. Family Health History tools are preventative screening mechanisms meant to explore family history to better understand how an individual's health can potentially be predicted or impacted. These tools are underutilized in the African American community. Contributions to this underutilization include a lack of cultural tailoring in the tools, a lack of health literacy in community members, and a lack of effective health communication. The Family Health History Study will create a culturally appropriate Family Health History toolkit to increase family health history utilization and ultimately decrease health disparities. Methods The proposed sample will be composed of 195 African American adults ages 18 + who live in Genesee County, Michigan. The study consists of two phases: the development phase and the randomized pilot study phase. The goal of the development phase (n = 95) is to explore how Family Health History toolkits can be modified to better serve the African American community using a community based participatory research approach and to create a culturally tailored family health history toolkit. In the pilot study phase, 100 participants will be randomized to the culturally tailored toolkit or the current standard Family Health History toolkit. Outcomes will include feasibility and acceptability of the intervention. Discussion This study will result in a culturally appropriate Family Health History tool that is co-developed with community members that can be utilized by African American adults to better understand their family health histories. Trial Registration Clinicaltrials.gov: NCT05358964 Date: May 5, 2022.

The landscape of self-care in Australia: A pharmacy perspective

The evolving landscape of self-care in Australia underscores the imperative of recognizing and integrating the crucial role of pharmacists in promoting greater levels of self-care. Although the social and economic justifications for self-care are acknowledged internationally and in the literature, there is very little policy recognition in relation to self-care specifically in Australian health policy. Additionally, the distinct contributions of pharmacies to self-care, i.e., their experiences and accessibility in primary health care, are not consistently highlighted. Community pharmacies in Australia are currently navigating a transformative shift, expanding their scope of practice to deliver highly individualized care, with a special emphasis on the implementation of professional services crucial for the sector's enduring viability. Although pharmacists already play a substantial role in supporting self-care, there exists a compelling demand for a systematic and structured approach. Despite the limited availability of theoretical frameworks or models for pharmacists in self-care support within the existing literature, tangible practical evidence attests to the success of interventions. In an era where patients increasingly assume responsibility for self-managing conditions, the pharmacist's role in facilitating self-care and judicious self-medication is pivotal, promising not only tangible benefits for individuals but also contributing significantly to the long-term sustainability of the healthcare system in Australia. This necessitates a strategic and comprehensive framework that positions pharmacists as essential catalysts in the broader landscape of healthcare, ensuring their contributions are optimally leveraged to enhance patient outcomes and system efficiency.

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.

Frailty and medication adherence among older adult patients with hypertension: a moderated mediation model

Objective

Medication adherence has a critical impact on the well-being of older adult patients with hypertension. As such, the current study aimed to investigate the mediating role of health literacy between frailty and medication adherence and the moderating role of educational level.

Methods

This cross-sectional study included patients admitted to the geriatric unit of a hospital. Participants were interviewed using the four-item Morisky Medication Adherence Scale, the Frailty Phenotype Scale, and the Health Literacy Management Scale. Spearman's correlation coefficients were used to assess the association between variables. Mediation and moderated mediation analyses were performed using Process version 4.1 via Model 4 and 14, respectively.

Results

Data from 388 participants were analyzed. The median (IQR [P25-P75]) score for medication adherence was 4.00 (2.00-4.00). Results revealed that after controlling for age, sex, hypertension complication(s) and body mass index, frailty significantly contributed to medication adherence (βtotal -0.236 [95% confidence interval (CI) -0.333 to -0.140]). Medication adherence was influenced by frailty (βdirect -0.192 [95% CI -0.284 to -0.099]) both directly and indirectly through health literacy (βindirect -0.044 [95% CI -0.077 to -0.014]). Educational level moderated the pathway mediated by health literacy; more specifically, the conditional indirect effect between frailty and medication adherence was significant among older adult hypertensive patients with low, intermediate, and high educational levels (effect -0.052 [95% CI -0.092 to -0.106]; effect -0.041 [95% CI -0.071 to -0.012]; effect -0.026 [95% CI -0.051 to -0.006]). The relationship between frailty and medication adherence in older adult patients with hypertension was found to have mediating and moderating effects.

Conclusion

A moderated mediation model was proposed to investigate the effect of frailty on medication adherence. It was effective in strengthening medication adherence by improving health literacy and reducing frailty. More attention needs to be devoted to older adult patients with hypertension and low educational levels.

Empowerment and quality of life: the mediating role of self-efficacy and health literacy among spousal caregivers in China

The aim of this study was to explore the chain mediation model of self-efficacy and health literacy between empowerment and quality of life among spousal caregivers of disabled elderly based on 'Marriage Binding'. From December 2020 to June 2022, the cross-sectional study was conducted in hospitals and communities, in Guangdong, Fujian, Sichuan, Hunan, Jiangxi, Guangxi and Yunnan provinces, China. Descriptive statistics were used to describe the demographic data and four main variables, including empowerment, self-efficacy, health literacy and quality of life. Spearman correlation analysis was used to analyze the correlation between the four main research variables. Multiple Linear Regression and bootstrap analysis were used to analyze the direct and indirect effects among them. Any two variables of spousal caregivers were correlated among empowerment, self-efficacy, health literacy and quality of life. Self-efficacy and health literacy can separately and sequentially mediate the relationship between empowerment and quality of life. To improve the quality of life of spousal caregivers of disabled elderly, the mediating role of self-efficacy, the mediating role of health literacy and the chain mediating role of self-efficacy and health literacy should take effect. In the future, some intervention studies should be taken to enhance the effects of those variables that may be beneficial for improving quality of life of spousal caregivers of disabled elderly.

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

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

Self-efficacy and self-management mediate the association of health literacy and quality of life among patients with TB in Tibet, China: a cross-sectional study

BACKGROUND

This study aimed to analyze the relationship between health literacy and quality of life in patients with TB in Tibet and explore the mediating effects of self-efficacy and self-management in the relationship between health literacy and quality of life.

METHODS

We used a convenience sampling method to select 271 cases of patients with TB in Tibet to conduct a survey of their general information, health literacy, self-management, self-efficacy and quality of life, and to construct structural equation models.

RESULTS

The total health literacy score of patients with TB in Tibet was 84.28±18.57, while the lowest score was for information acquisition ability (55.99±25.66). Scores for quality of life were generally lower than the norm (patients with chronic diseases from other cities in China) (p<0.01). Moreover, self-efficacy and self-management mediated the relationship between health literacy and quality of life (p<0.05).

CONCLUSIONS

In Tibet, patients with TB have a low level of health literacy and an average level of quality of life. Emphasis should be placed on improving information access literacy, role-physicals and role-emotional to improve overall quality of life. The mediating roles of self-efficacy and self-management between health literacy and quality of life may provide a basis for further interventions.

A structural equation model linking health literacy, self-efficacy, and quality of life in patients with polycystic ovary syndrome

BACKGROUND

Health literacy is a crucial factor that affects health outcomes. Understanding the current status of health literacy among patients with polycystic ovary syndrome (PCOS) is the basis for helping patients better manage risk factors and improve their health outcomes. This study aimed to explore the status of and factors influencing health literacy in patients with PCOS, and to validate the pathway between health literacy, quality of life, and self-efficacy for these patients.

METHODS

A cross-sectional study was conducted using a convenience sample of 300 patients with PCOS in the gynecology outpatient clinic of a tertiary hospital in Zunyi from March to September 2022. Data on health literacy, demographic features, quality of life, and self-efficacy were collected. Multiple stepwise linear regression was conducted to assess the risk factors associated with health literacy for the study participants. A structural equation model was used to construct and validate the pathways.

RESULTS

Most participants exhibited low health literacy (3.61 ± 0.72), and only 25.70% had adequate health literacy. Multiple regression analysis revealed that the main factors associated with health literacy among participants included Body Mass Index (BMI) (B = -0.95, p < 0.01), education (B = 3.44, p < 0.01), duration of PCOS (B = 4.66, p < 0.01), quality of life (B = 0.25, p < 0.01), and self-efficacy (B = 0.76, p < 0.01). Multiple fit values indicated that the model fit the data effectively. The direct effect of health literacy on self-efficacy and quality of life was 0.06 and 0.32, respectively. The indirect effect of health literacy on quality of life was -0.053, and the total effect of health literacy on quality of life was 0.265.

CONCLUSIONS

Health literacy was low among patients with PCOS. Healthcare providers should pay more attention to health literacy and to developing the corresponding intervention strategies urgently needed to improve the quality of life and health behavior of patients with PCOS.

Development and validation of a comprehensive health literacy tool for adults in Hong Kong

Introduction

Health literacy (HL) refers to an individual's ability to process and use health information to make health-related decisions. However, previous HL scales did not fully cover all aspects of this concept. This study aimed to develop a comprehensive Hong Kong HL scale (HLS-HK) and evaluate its psychometric properties among Chinese adults.

Methods

A scale of 31-item covering Nutbeam's framework, namely functional and interactive HL (FHL and IHL), and critical HL (CHL) within three subdomains: critical appraisal of information, understanding of social determinants of health, and actions to address social determinants of health, was developed based on previous literature review and Delphi survey. Cognitive interviews were performed to examine all items' face validity in terms of three aspects: comprehensiveness, clarity, and acceptability. A cross-sectional survey was conducted to investigate the scale's psychometric properties, including its internal consistency reliability, factorial structure validity, convergent validity, and predictive validity.

Results

Nine interviewees participated in the cognitive interviews in October 2021. Based on the input from respondents, two items were deleted, two items were combined, and several items' wording was revised. The other items were clear and readable. Finally, 28 items remained. A total of 433 adults completed the questionnaire survey between December 2021 and February 2022. After excluding one item with low inter-item correlations, the scale's internal consistency reliability was acceptable, with a Cronbach's alpha of 0.89. Exploratory factor analysis produced a five-factor model, as shown in the original theoretical framework. These factors accounted for 53% of the total variance. Confirmatory factor analysis confirmed that the fit indices for this model were acceptable (comparative fit index = 0.91, root mean square error of approximation = 0.06, and root mean square residual = 0.06). The scale is also significantly correlated with theoretically selected variables, including education and self-rated health.

Conclusion

The HLS-HK is a valid and reliable tool for evaluating HL. Compared with existing tools, this scale extended the operationalization of FHL, IHL, and CHL and fully operationalized the CHL via three subdomains. It can be used to understand the difficulties and barriers that people may encounter when they use health-related information and services.

Exploring Health Literacy Categories in Patients With Heart Failure: A Latent Class Analysis

BACKGROUND

Although a growing number of studies have demonstrated that patients' health literacy is associated with health outcomes, the exact relationship between them is not clear.

AIMS AND OBJECTIVES

The aim of this study was to explore latent classes of health literacy in patients with heart failure and analyze the differences among different groups.

DESIGN AND METHODS

This is a cross-sectional survey. Patients diagnosed with heart failure were selected from 3 tertiary hospitals in Tianjin, China, from March 2019 to November 2019. We measured patients' health literacy using the Health Literacy Scale for Chronic Patients. Latent class analysis was carried out based on the patients' Health Literacy Scale for Chronic Patients scores. Multinomial logistic regression was used to identify the predictive indicators of the latent classes.

RESULTS

The health literacy of patients with heart failure was divided into 3 different latent classes, named "high health literacy group," "low literacy high dependence group," and "moderate literacy high willingness group." There were statistically significant differences in gender, age, smoking history, marital status, education level, household income level, and quality of life among different health literacy classes. Low education level and household income level predicted poor health literacy.

CONCLUSION

There were 3 latent classes for the health literacy of patients with heart failure. Different health literacy classes exhibited their own distinctive characteristics. Patients in the "moderate literacy high willingness group" had the worst quality of life. Understanding the specific types of health literacy in patients with heart failure facilitates targeted nursing interventions to improve their quality of life.

Health literacy and quality of life of patients with coronary heart disease in Tibet, China: The mediating role of self-efficacy and self-management

BACKGROUND

The disease burden of coronary heart disease patients in Tibet, China, ranks high in the country. Due to the local culture and environment, patients with coronary heart disease have increased risk factors for the disease, and their survival is worrisome.

OBJECTIVES

The purpose of this study was to determine the relationship between health literacy and quality of life for patients with coronary heart disease in Tibet, China, and to explore the mediating roles of self-efficacy and self-management.

METHODS

A cross-sectional study was conducted from August 2020 to July 2021 in Tibet. A total of 258 patients with coronary heart disease in Tibet participated. Self-reported questionnaires were used to assess health literacy, self-efficacy, self-management, and quality of life. Pearson correlation analysis and the SPSS PROCESS macro were used to analyze the data.

RESULTS

The mean total score for the health literacy of patients with coronary heart disease in Tibet was 3.59 ± 0.80 points, showing the existence of a limited level of literacy. The quality of life was of an average level, with scores of 57.20 ± 21.70 points and 63.63 ± 20.66 points for physical and mental status, respectively. Self-efficacy and self-management mediated the relationship between health literacy and quality of life.

CONCLUSIONS

Self-efficacy and self-management mediate the relationship between health literacy and quality of life. Targeted interventions for health literacy, self-efficacy, and self-management skills are important to improve the quality of life of Tibetan patients with coronary heart disease.

Consumer Access, Appraisal, and Application of Services and Information for Dementia (CAAASI-Dem): a validation study

Objectives: The Consumer Access, Appraisal, and Application of Services and Information for Dementia (CAAASI-Dem) was developed to examine individuals' self-assessed confidence in their ability to access, appraise and use dementia services and information. The CAAASI-Dem is the only tool to date to measure this crucial component of dementia literacy. This study was designed to validate its structural validity.Method: Data was collected from 3277 participants enrolled in an on-line dementia course. The five-factor structure of the CAAASI-Dem, which was derived from a previous exploratory factor analysis, was evaluated using confirmatory factor analysis. Internal reliability, convergent and divergent validity, and known-groups validity were assessed. Results: The five-factor model demonstrated good fit with the observed data with the removal of 2 items and movement of 1 item across the factors. The resultant 24-item five-factor CAAASI-Dem showed very good sub-scale internal reliability and satisfactory convergent and divergent validity. There was good discrimination between groups of participants with different levels of care experience.Conclusion: The results provided evidence for the 24-item CAAASI-Dem as a valid and reliable five-dimensional scale. Limitations of the study are discussed, and recommendations are made for future research and practice.

Developing a Health Literacy Scale for adults in Hong Kong: A modified e-Delphi study with healthcare consumers and providers

INTRODUCTION

Health literacy (HL) refers to individuals' abilities to process and use health information to promote health. This study aimed to develop the first HL measurement tool for the Chinese Hong Kong population.

METHODS

A two-phase methodology was adopted. In Phase I, evidence synthesis with a deductive method was conducted to formulate the item list from the literature. In Phase II, a modified e-Delphi survey was conducted among stakeholders (i.e., healthcare providers and healthcare consumers) to confirm the content validity of the item list. The stakeholders were invited to rate the relevance of each draft item on a 4-point scale and provide suggestions for revisions, removal or adding new items.

RESULTS

In Phase I, a total of 34 items covering functional, interactive and critical HL were generated. In Phase II, to obtain a balanced view from experts and laypeople, healthcare professionals (n = 12) and consumers (n = 12) were invited to participate in the Delphi panel. The response rates of the three rounds were 100%. After the third round, the consensus was reached for 31 items, and no further comments for adding or revising items were received. All items exhibited excellent content validity (item content validity index: 0.79-1.00; K*: 0.74-1.00).

CONCLUSIONS

A Health Literacy Scale for Hong Kong was developed. Compared with existing HL scales, the scale fully operationalized the skills involved in functional, interactive and critical HL. The Delphi study shows evidence supporting the high content validity of all items in the scale. In future studies, these items should undergo rigorous testing to examine their psychometric properties in our target population groups. By illuminating the details in the development process, this paper provides a deeper understanding of the scale's scope and limitations for others who are interested in using this tool.

PATIENT OR PUBLIC CONTRIBUTION

Public as healthcare consumers, in addition to healthcare providers, were involved in developing a new HL scale for this study. The input from the public contributed to examining the scale's content validity by judging whether all items reflected the skills that they need to find and use health-related information in their daily life.

Modelling variance in the multidimensional Health Literacy Questionnaire: Does a General Health Literacy factor account for observed interscale correlations?

Objectives

Self-report measures of health literacy frequently encompass a group of conceptually distinct but related domains scored as either a single scale or separately for each domain. Psychometric studies of the 44-item Health Literacy Questionnaire, scored as nine separate scales, typically report the results of correlated factors confirmatory factor analyses as validity evidence. However, some scales are quite strongly correlated, raising the question of whether there is sufficient discriminant validity to warrant separate scoring. This psychometric study aims to contrast the results of fitting higher-order and bifactor models as alternative options to illuminate the issue.

Methods

Correlated factors, higher-order and bifactor confirmatory factor analysis models were fitted to an Australian sample of responses to the Health Literacy Questionnaire (N = 813) using Bayesian confirmatory factor analysis methods.

Results

All models representing a nine-factor structure for the Health Literacy Questionnaire fitted well. The correlated factors model replicated previous findings, showing inter-factor correlations between 0.19 and 0.93. A higher-order model showed relatively high loadings of all nine first-order factors on the second-order factor with particularly high loadings (⩾0.97) for three. Two bifactor models showed that the majority of Health Literacy Questionnaire items were multifactorial, each containing systematic variance from both a General Health Literacy factor and a domain-specific factor. Seven items from four scales were identified as strongly associated with the General Health Literacy factor, with item content suggesting that this factor indexes a broad sense of agency and efficacy in interacting with health-related information and healthcare providers.

Conclusion

Contrasting correlated factors, higher-order and bifactor models fitted to the Health Literacy Questionnaire suggest that constituent items in self-report health literacy questionnaires might be anticipated to represent at least two sources of reliable and substantive common factor variance: variance associated with General Health Literacy and variance associated with a more specific domain, suggesting that items may be 'irreducibly' heterogeneous. Implications for test development and validation practice are discussed.

Post-treatment Outcomes and Changes in Health Literacy of People Discharged from Specialist Substance Use Disorder Treatment Services

Health literacy comprises an individual’s ability to adequately access, understand and utilise health information, enabling effective navigation of the healthcare system. Low health literacy is a problem for people living with substance use disorders (SUDs). This study aims to examine whether health literacy changes for people discharged from specialist SUD treatment services. Two hundred thirty-one people recruited from residential SUD treatment services across New South Wales, Australia, completed a questionnaire upon entry into the service and again at 6 months post-treatment. Treatment outcomes were also measured. Three health literacy profiles were identified: lowest (n = 52, 22.5%), moderate (n = 111, 48.1%) and highest health literacy (n = 68, 29.4%). Lowest and moderate profiles showed improved health literacy at 6 months. However, the lowest profile still had significantly lower health literacy, quality of life and higher levels of psychological distress compared with participants in the highest profile at 6 months. People within the lowest health literacy profile improved, although they continued to experience lower health literacy and some poorer treatment outcomes. Health literacy interventions tailored for people within lowest health literacy profiles should be implemented and assessed for effectiveness within specialist SUD treatment services.

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.

Senior High School Students' Knowledge and Attitudes Toward Information on Their Health in the Kumasi Metropolis

The study examines senior high school students' understanding and attitudes toward information on their health in the Kumasi Metropolis. Multiple sampling techniques (convenient and simple random sampling techniques) were used in the study. A questionnaire was used to collect data from 391 respondents for the study. Frequencies and percentages were used to analyze the sociodemographic data. Again, the study used Pearson's correlation coefficient to show the degree of relationship between the level of knowledge of health information and attitudes toward seeking and sharing health information. The study found students' knowledge of the causes and symptoms of malaria, cholera, and Sexually Transmitted Infections (STIs) to be appreciably high as a result of readings from textbooks and health professionals. Again, the study found that the students preferred sharing their health information with friends than their parents and schools' authorities. The study further found that the major sources of students' health information included health professionals and textbooks. Lastly, even though some of the students claimed internet sources to their health information, it was not a major source to the student body at large. The study recommends strong health systems on the campuses of senior high schools as they have become communities on their own as a result of the emergence of the free senior high school program. The monitored positive peer-counseling group should also be encouraged by the schools' management and by extension the counseling units for the students to share views on themselves, particularly on health issues where they deem fit.

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.

Definitions and measurement of health literacy in health and medicine research: a systematic review

OBJECTIVES

The way health literacy is understood (conceptualised) should be closely linked to how it is measured (operationalised). This study aimed to gain insights into how health literacy is defined and measured in current health literacy research and to examine the relationship between health literacy definitions and instruments.

DESIGN

Systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

DATA SOURCES

The MEDLINE, PsycINFO, ERIC and CINAHL databases were searched for articles published during two randomly selected months (March and October) in 2019.

ELIGIBILITY CRITERIA

We included articles with a quantitative design that measured health literacy, were peer-reviewed and original, were published in the English language and included a study population older than 16 years.

DATA EXTRACTION AND SYNTHESIS

Six researchers screened the articles for eligibility and extracted the data independently. All health literacy definitions and instruments were considered in relation to category 1 (describing basic reading and writing skills, disease-specific knowledge and practical skills) and category 2 (social health literacy competence and the ability to interpret and critically assess health information). The categories were inspired by Nutbeam's descriptions of the different health literacy levels.

RESULTS

120 articles were included in the review: 60 within public health and 60 within clinical health. The majority of the articles (n=77) used instruments from category 1. In total, 79 of the studies provided a health literacy definition; of these, 71 were in category 2 and 8 were in category 1. In almost half of the studies (n=38), health literacy was defined in a broad perspective (category 2) but measured with a more narrow focus (category 1).

CONCLUSION

Due to the high degree of inconsistency between health literacy definitions and instruments in current health literacy research, there is a risk of missing important information about health literacy considered be important to the initial understanding of the concept recognised in the studies.

Assessing healthcare expenditures of older United States adults with pain and poor versus good mental health status: a cross-sectional study

OBJECTIVES

This study aimed to determine if differences exist in healthcare expenditures of older United States (US) adults with pain based on self-reported mental health status, which is important to know given the prevalence of pain and poor mental health in the USA.

DESIGN

This was a cross-sectional study.

SETTING

US Medical Expenditure Panel Survey (MEPS) interviews.

PARTICIPANTS

US adults aged ≥50 years, with self-reported pain in the past 4 weeks and positive healthcare expenditure in the 2018 Medical Expenditure Panel Survey (MEPS). The independent variable was poor versus good mental health status.

PRIMARY AND SECONDARY OUTCOME MEASURES

Descriptive statistics compared demographic characteristics (using chi-square tests) and mean healthcare expenditures (using t-tests) between groups. Adjusted linear regression models with logarithmically-transformed expenditures compared differences in: total; inpatient; outpatient; emergency room; office-based; prescription medications and other expenditures. Analyses accounted for the complex MEPS design and were weighted to produce nationally-representative results. The a priori alpha level was 0.05.

RESULTS

The weighted population included 57 134 711 older US adults with self-reported pain (14.4% poor mental health, 85.6% good mental health). Compared with individuals with good mental health, individuals with poor mental health had higher unadjusted total expenditures (US$20 231 vs US$13 379, p<0.0001), higher prescription medication expenditures (US$5924 vs US$3610, p<0.0001) and higher other expenditures (US$4833 vs US$2285, p<0.0001). In adjusted multivariable linear regression models, there were no differences in expenditures between those with poor mental health and those with good mental health status.

CONCLUSIONS

There were no statistically significant differences in adjusted annual (2018) positive healthcare expenditures among older US adults with pain and poor versus good mental health status.

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.

Development and Validation of the Health Literacy Assessment Instrument for Patients with Chronic Pain

A suitable health literacy assessment instrument for patients with chronic pain (HLCP) in China with good instrument's psychometric properties is required. A theoretical framework for the HLCP was developed by adopting the hierarchical model of health literacy proposed by Nutbeam. The reliability and validity of the HLCP were tested in a cross-sectional survey of 237 chronic pain patients from three pain clinics and wards of Grade-3A hospitals in Zhejiang Province, China. The discriminant degree method, correlation analysis method, factor analysis method (exploratory factor analysis), half reliability, and other methods were utilized to screen items for inclusion in the final version of HLCP, and the fitness of the model was subsequently evaluated by confirmatory factor analysis. Cronbach's alpha value and test-retest with two-week intervals were used to test the internal consistency and retest reliability of the HLCP. In the exploratory factor analysis, three domains, functional health literacy (10 items), interactive health literacy (14 items), and critical health literacy (7 items), comprising 31 items in total, were finally loaded; the model was determined to explain 70.9% of the total variance. HLCP's effective assessment of the health literacy level of patients with chronic pain and its acceptable reliability and validity were revealed through the results.

Health literacy and health outcomes in patients with low back pain: a scoping review

BACKGROUND

Low back pain is a leading cause of disability worldwide. Health literacy has been associated with pain intensity and pain control. However, there is a paucity of evidence regarding this association. In the field of low back pain research, inconsistent reporting of outcomes has been highlighted. To address this issue a Core Outcome Set has been developed.

OBJECTIVES

The objectives of this scoping review were: (1) The health literacy measures currently employed for low back pain and the aspects of health literacy they include. (2) The low back pain health outcomes included in such work. (3) The extent to which these health outcomes reflect the Core Outcome Set for Clinical Trials in Non-Specific Low Back Pain.

METHODS

The search included thirteen bibliographic databases, using medical subject heading terms for low back pain and health literacy, and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. The eligibility criteria were defined by the Joanna Briggs Institute PCC mnemonic. A thematic framework approach was used for analysis.

RESULTS

The search yielded ten relevant studies for inclusion, amongst which a total of nine health literacy measures and 50 health outcome measures were used. Most health literacy measures focused on functional health literacy, with few assessing communicative and critical health literacy. The health outcomes assessed by the included studies could be broadly categorised into: Pain, Disability, Behaviour, Knowledge and Beliefs, and Resource Utilisation. Most of these outcome measures studied (36 out of 50) did not directly reflect the Core Outcome Set for Clinical Trials in Non-Specific Low Back Pain.

CONCLUSIONS

To allow for comparison across findings and the development of a rigorous evidence base, future work should include the Core Outcome Set for Clinical Trials in Non-Specific Low Back Pain. There is an urgent need to broaden the evidence-base to include regions where low back pain morbidity is high, but data is lacking. Such work demands the incorporation of comprehensive measures of health literacy that have both generic and culturally sensitive components.

[Impact of health literacy on patient experience of outpatients in China and its mechanism]

OBJECTIVE

To understand the relationship between health literacy and patient experience of outpatients in China, and to explore its mechanism.

METHODS

The conceptual framework was developed based on Andersen's behavioral model of health services use and health literacy skills framework. An online cross-sectional survey was conducted with snowball sampling method, while the health literacy was measured by self-designed patient health literacy scale, and the patient experience was measured by the Chinese patient experience questionnaire for ambulatory care developed by Peking Union Medical College. And a structural equation model was built to explore the relationship between them and test the mechanism of health literacy influencing patient experience.

RESULTS

A total of 2 773 subjects were investigated. The average score of health literacy was (90.72±12.90) points, accounting for 78.89% of the full score, and the dimension of seeking social support had the lowest score. The average score of overall rating of patient experience was (3.71±0.74) points, and the scores of each dimension of patient experience were between 3.56 and 3.80. The model fit indices of structural equation model for overall rating of patient experience among the outpatients were χ²/df=9.29 (χ²=4 107.27, df=442), root mean square error of approximation (RMSEA)=0.055 (< 0.06), comparative fit index (CFI)=0.926 (>0.90), Tucker-Lewis index (TLI)=0.918 (>0.90), standardized root mean square residual (SRMR)=0.061 (< 0.08), the model was acceptable. The variance in patient experience explained by the model was 0.108. The structural equation model analysis results showed that the overall rating of outpatient experience was directly affected by health literacy (β=0.263, P < 0.001), also indirectly affected by health literacy (β=0.012, P < 0.001). In other words, the overall rating increased by 0.275 units for each standard deviation increase of health literacy. Self-evaluated health status mediated the relationship between health literacy and the overall rating of outpatient experience. In terms of diffe-rent dimensions of patient experience, the standardized path coefficient of the total effect of health literacy on patient experience was as follows: Information guidance 0.337, humanistic care 0.319, communication with doctors 0.294, service efficiency 0.240, and hospital environment 0.173.

CONCLUSION

The patients with higher level of health literacy were more likely to have a better outpatient experience in China, and the information guidance experience and humanistic care experience were most affected by health literacy. And the communication and information utilization ability had the greatest influence on patient experience.

Gamifying health literacy: how can digital technology optimize patient outcomes in surgery?

The digital age is entrenched in our society, with constant innovation driving change in the way clinicians and patients manage their health concerns. Health literacy is emerging as an important modifiable factor that can affect clinical and patient outcomes, yet traditional forms of patient education have shown mixed results. Digital media and technologies, the concept of gamification as a means to improve patient health literacy, and its potential for misuse will be explored in this review, in the context of a digital, gamified tool that could support patients along their surgical journey.

Health literacy levels of British adults: a cross-sectional survey using two domains of the Health Literacy Questionnaire (HLQ)

Background

A person’s health literacy determines whether they are able to make appropriate health decisions and are able to follow treatment instructions. This is important because low health literacy is associated with mortality and extra costs to the healthcare system. Our aim was to describe the health literacy levels of British adults using a nationally representative population survey, and show how health literacy levels vary by population characteristics.

Methods

A population based cross-sectional survey including questions from two domains from the Health Literacy Questionnaire™: 1) Understanding health information well enough to know what to do, and 2) Ability to actively engage with health care providers. Both domains are made up of 5 Likert style questions with 5 levels ranging from ‘cannot do or always difficult’ (1) to ‘always easy’ (5). The survey was conducted by NatCen in Britain (2018) as part of the annual British Social Attitudes survey. We used weighted descriptive analyses and regression to explore the relationship between population characteristics and health literacy. Weighted analyses were used to ensure the sample was representative of the British population.

Results

A total of 2309 responded to the questionnaire. The mean score for ‘understanding information’ was 3.98 (95% CI: 3.94, 4.02) and for ‘ability to engage’ was 3.83 (95% CI: 3.80, 3.87), where 5 is the highest score. 19.4% had some level of difficulty reading and understanding written health information, and 23.2% discussing health concerns with health care providers. The adjusted logistic regression for ‘understanding information’ showed that those with lower health literacy were more likely to be in the most socially deprived quintile (OR 2.500 95% CI: 1.180, 5.296), have a limiting health condition or disability (OR 4.326 95% CI: 2.494, 7.704), and have no educational qualifications (OR 7.588 95% CI: 3.305, 17.422). This was similar for the ‘ability to engage’ domain.

Conclusions

This study described the distribution of health literacy levels for the British population in 2018. Interventions to improve health literacy will best be targeted at those with lower levels of education, those living in the most deprived areas, and those with a limiting health condition or disability.

Measuring consumer access, appraisal and application of services and information for dementia (CAAASI-Dem): a key component of dementia literacy

BACKGROUND

The ability to locate, navigate and use dementia services and information, either for oneself or in providing care for others, is an essential component of dementia literacy. Despite dementia literacy being understood to be inadequate in many settings, no validated instrument exists to measure these elements. Here we describe the development and preliminary validation of the Consumer Access, Appraisal and Application of Services and Information for Dementia (CAAASI-Dem) tool.

METHODS

Items were adapted from existing health literacy tools and guided by discussion posts in the Understanding Dementia Massive Open Online Course (UDMOOC). Following expert review and respondent debriefing, a modified CAAASI-Dem was administered to UDMOOC participants online. On the basis of descriptive statistics, inter-item and item total correlations and qualitative feedback, this was further refined and administered online to a second cohort of UDMOOC participants. Exploratory factor analysis identified underlying factor structure. Items were retained if they had significant factor loadings on one factor only. Each factor required at least three items with significant factor loadings. Internal consistency of factors in the final model was evaluated using Cronbach's alpha coefficients.

RESULTS

From a pool of 70 initial items with either a 5-point Likert scale (Not at all confident - Extremely confident; or Strongly agree - Strongly disagree) or a binary scale (Yes - No), 65 items were retained in CAAASI-Dem-V1. Statistical and qualitative analysis of 1412 responses led to a further 34 items being removed and 11 revised to improve clarity. The 31 item CAAASI-Dem-V2 tool was subsequently administered to 3146 participants, one item was removed due to redundancy and EFA resulted in the removal of an additional 4 items and determination of a five factor structure: Evaluation and engagement; Readiness; Social supports; Specific dementia services; and Practical aspects.

CONCLUSIONS

The five factors and 26 constituent items in CAAASI-Dem align with functional, critical, and communicative aspects of dementia health literacy from the perspective of the carer. As a screening tool for people living with dementia and their carers, CAAASI-Dem potentially provides a means to determine support needs and may be a key component of the dementia literacy assessment toolbox.

Measurement properties of self-report instruments to assess health literacy in older adults: a systematic review

BACKGROUND

High health literacy (HL) is important to optimise health outcomes, particularly for older people (who are substantial consumers of health services) and their adult caregivers. The aim of this systematic review was to evaluate measurement properties of HL instruments tested with these population groups.

MATERIALS AND METHODS

Six databases (MEDLINE (OVID); CINAHL; EMBASE (OVID); PsycInfo; Scopus; Cochrane Library) were searched for studies evaluating eight measurement properties of HL tools administered to older people or their caregivers. Only studies evaluating multi-domain self-report HL tools were included in analyses, using the COSMIN methodology.

RESULTS

From 4261 unique papers located, 11 met inclusion criteria; six reported measurement properties of three HL self-report tools administered to older people (HLQ, eHEALS, and HeLMS) so are reported in this review, none involved caregiver samples. The HLQ and HeLMS were rated "moderate," and eHEALS "low" for tool development. The HLQ, examined in four included studies, had the highest ratings and quality of evidence across the three measurement properties investigated in included papers.

CONCLUSION

The HLQ was the most highly rated self-report HL tool of just three tested with older people. Further studies evaluating measurement properties of self-report HL tools used with older people and/or their caregivers are needed.Implications for rehabilitationHealth literacy is important to optimise health outcomes of interventions for older people and their adult caregivers.Few studies have evaluated measurement properties of self-report / multi-domain health literacy tools for this population.The Health Literacy Questionnaire (HLQ) had the highest ratings and quality of evidence across the three measurement properties investigated in included studies, and is recommended for use in rehabilitation settings.

Health Literacy in Surgery

Background:

Low health literacy is associated with poor health outcomes in many chronic diseases and may have an important role in determining surgical outcomes. This study aims to comprehensively review the current state of science on adult health literacy in surgery and to identify knowledge gaps for future research.

Methods:

Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a systematic search was conducted to identify all studies from January 2002 through May 2018 that used validated instruments to assess health literacy among adult patients undergoing surgery. Studies were assessed for quality using the Newcastle-Ottawa scale and evaluated on findings by their focus on identifying health literacy levels, understanding associations with surgical outcomes, and/or developing interventions to address low health literacy.

Key Results:

There were 51 studies on health literacy with data from 22,139 patients included in this review. Low health literacy was present in more than one-third of surgical patients (34%, interquartile range 16%–50%). The most commonly used validated instrument for assessment of health literacy in the surgical population was the Newest Vital Sign. Most studies were focused on identifying the prevalence of low health literacy within a surgery population (84%, n = 43). Few studies focused on understanding the association of health literacy to surgical outcomes (12%, n = 6) and even fewer studies developed interventions to address health literacy (4%, n = 2).

Discussion:

Low health literacy is common among surgical patients. Important opportunities exist to better understand the role of health literacy in determining surgical outcomes and to develop more health literacy-sensitive models of surgical care. [HLRP: Health Literacy Research and Practice. 2020;4(1):e45–e65.]

Plain Language Summary:

Health literacy has not been well-studied in surgery but likely plays an important role. In this article, we reviewed all current research on health literacy in surgery to help us understand where we are at and where we need to go. We found that low health literacy is common and we need more ways to address it in surgery.

Generic Health Literacy Measurements for Adults: A Scoping Review

BACKGROUND

Generic health literacy measurement (GHLM) is an important tool to identify individuals with limited health literacy and can assist the design of tailored interventions for improving public health literacy. However, there is no consensus on measuring generic health literacy. The present study aims to review current GHLM used for adults in the literature.

METHODS

A scoping review was undertaken to map the available measurements designed to assess generic health literacy.

RESULTS

The review identified 19 GHLM for adults. Most of them applied a multidimensional definition of health literacy with a focus on individuals' abilities to access, appraise, understand, and apply health information and services. Nutbeam's conceptual model and Sørensen's integrated model were widely used among the identified measures as the theoretical foundation. While the social determinants of health (SDH) were acknowledged in the two models, it remains unmentioned in many of the identified measures based on the Nutbeam's model and needs further development in the measure based on the Sørensen's model. A total of 39 different domains were assessed in the 19 measurements: prose was identified in 8 measurements and was the most prominent domain; followed by numeracy (n = 7) and interactive (n = 7). SDH related domains such as social support (n = 3), social capital (n = 1) were seldom included in the identified measurements.

CONCLUSIONS

Although current GHLM adopted a multidimensional construct, they mainly focused on individuals' abilities and SDH has not been well-developed in the assessment. Further research is required to advance the measuring of the interaction between SDH and health literacy.

Questionnaire validation practice within a theoretical framework: a systematic descriptive literature review of health literacy assessments

OBJECTIVE

Validity refers to the extent to which evidence and theory support the adequacy and appropriateness of inferences based on score interpretations. The health sector is lacking a theoretically-driven framework for the development, testing and use of health assessments. This study used the Standards for Educational and Psychological Testing framework of five sources of validity evidence to assess the types of evidence reported for health literacy assessments, and to identify studies that referred to a theoretical validity testing framework.

METHODS

A systematic descriptive literature review investigated methods and results in health literacy assessment development, application and validity testing studies. Electronic searches were conducted in EBSCOhost, Embase, Open Access Theses and Dissertations and ProQuest Dissertations. Data were coded to the Standards' five sources of validity evidence, and for reference to a validity testing framework.

RESULTS

Coding on 46 studies resulted in 195 instances of validity evidence across the five sources. Only nine studies directly or indirectly referenced a validity testing framework. Evidence based on relations to other variables is most frequently reported.

CONCLUSIONS

The health and health equity of individuals and populations are increasingly dependent on decisions based on data collected through health assessments. An evidence-based theoretical framework provides structure and coherence to existing evidence and stipulates where further evidence is required to evaluate the extent to which data are valid for an intended purpose. This review demonstrates the use of the Standards' theoretical validity testing framework to evaluate sources of evidence reported for health literacy assessments. Findings indicate that theoretical validity testing frameworks are rarely used to collate and evaluate evidence in validation practice for health literacy assessments. Use of the Standards' theoretical validity testing framework would improve evaluation of the evidence for inferences derived from health assessment data on which public health and health equity decisions are based.

Adherence behavior assessment of oral antidiabetic medication use: a study of patient decisions in long-term disease management in primary health care centers in Surabaya

Background Adherence to medication has an important role in the long-term management of diabetes. The Indonesian Endocrinologist Association found that of the 50% of the entire population who have been diagnosed with diabetes, two-thirds are undergoing therapy and only one-third have been achieving the intended outcomes of the drug therapy. This study aimed to identify patients' adherence behavior and the root causes of non-adherence. Methods This study used a non-experimental mixed-methods approach. A total of 40 patients with type 2 diabetes mellitus (T2DM), who were part of the referral program of the National Health Care Security System (BPJS Kesehatan) were recruited by purposive sampling from 17 primary health care centers in Surabaya, Indonesia. Results The adherence behavior assessment revealed non-adherence among 80% of the patients. The highest instances of non-adherence based on the percentage scores involved the following: patients forgot to take the medications (38.23%), patients preferred not to take the medications (20.59%) and the drug products were not available for the patient (14.71%). The factors influencing non-adherence included the complex instructions for taking medication, the absence of a reminder, the unwanted side effects of the drug, the feeling of repetition, the feeling that drugs were ineffective and the concern for the drug's effects on the kidney. Conclusions The high rates of non-adherence identified in this study encourage pharmacists to implement better medication therapy management for chronic diseases. The patients' understanding of drug therapy indications and regimens is very important in increasing the expectations of achieving effective treatment, awareness and concern for medication safety and treatment compliance.

"Some say no, some say yes": Receiving inconsistent or insufficient information from healthcare professionals and consequences for diabetes self-management: A qualitative study in patients with Type 2 Diabetes

AIMS

To explore the information-seeking experiences of patients with Type 2 diabetes and how these influenced self-management behaviours.

METHODS

We interviewed 18 patients with Type 2 Diabetes attending outpatient diabetes centers in South Western Sydney. Data were analyzed thematically.

RESULTS

Patients described a number of challenges they faced when seeking information about diabetes self-management. One major challenge was receiving inconsistent and insufficient information from healthcare professionals, which consequently undermined patients' ability to self-manage diabetes. This became a disincentive in carrying out self-management tasks, and led to confusion and mistrust regarding the veracity of information received. Participants also described finding reliable information, and difficulty understanding and accessing relevant information as challenges. Medical jargon and lack of comprehensive explanations exacerbated knowledge deficits compounded by the complex maze of internet resources that some patients accessed. In response to what they perceived as confusing or inconsistent information, some patients followed "their own way" of managing their diabetes.

CONCLUSIONS

Inconsistent information not tailored to the needs of patients adversely affects self-management. Taking time to provide simple explanations and assisting patients in navigating reliable web resources is becoming a vital role of healthcare professionals to reduce knowledge gaps in patients with low health literacy.

Access to health information, health literacy and health-related quality of life among women living with breast cancer: Depression and anxiety as mediators

OBJECTIVE

This study examined the direct and indirect influences of health literacy and access to health information on the quality of life among 205 women living with breast cancer in Ghana.

METHODS

A cross-sectional survey design was employed. The interviewer-administered instrument included the health literacy scale, questions on access and satisfaction with healthcare information, depression and anxiety scale, and the Functional Assessment of Cancer Therapy-Breast Cancer.

RESULTS

Access to health information and health literacy had significant indirect effects on quality of life through depression and anxiety. Whereas health literacy had direct influence on quality of life after controlling for other factors, access to information had no direct influence on quality of life.

CONCLUSION

Health literacy and access to health information improve quality of life in women living with breast cancer by reducing the levels of depression and anxiety. Depression and anxiety serve as possible mechanisms for the positive impacts of access to health information and health literacy on improved quality of life among breast cancer patients.

PRACTICE IMPLICATIONS

Health care providers need to ensure that the information needs of patients are met in oncology practice to reduce their negative emotional states which would lead to improved health and wellbeing.

A Web-Based Gamification Program to Improve Nutrition Literacy in Families of 3- to 5-Year-Old Children: The Nutriscience Project

OBJECTIVE

Assess the impact of a web-based gamification program on nutrition literacy of families and explore differences in impact by socioeconomic status.

DESIGN

Quasi-experimental.

SETTING

Thirty-seven kindergartens from Portugal.

PARTICIPANTS

Eight hundred seventy-seven families.

INTERVENTION

Web-based social network of participants' interactions, educational materials, apps and nutritional challenges, focused on fruit, vegetables, sugar, and salt.

MAIN OUTCOME MEASURES

Parental nutrition literacy (self-reported survey - 4 dimensions: Nutrients, Food portions, Portuguese food wheel groups, Food labeling).

ANALYSIS

General linear model - Repeated measures was used to analyze the effect on the nutrition literacy score.

RESULTS

Families uploaded 1267 items (recipes, photographs of challenges) and educators uploaded 327 items (photographs, videos) onto the interactive platform. For the intervention group (n = 106), the final mean (SD) score of nutrition literacy was significantly higher than the baseline: 78.8% (15.6) vs 72.7% (16.2); P < .001, regardless of parental education and perceived income status. No significant differences in the scores of the control group (n = 83) were observed (final 67.8% [16.1] vs initial 66.4% [15.6]; P = .364).

CONCLUSIONS AND IMPLICATIONS

Gamified digital interactive platform seems to be a useful, easily adapted educational tool for the healthy eating learning process. Future implementations of the program will benefit from longer time intervention and assessment of the eating habits of families before and after intervention.

A concept analysis of health literacy

AIM

To propose a conceptual definition of health literacy incorporating system demands, burdens, and complexities that are a critical part of patients' level of health literacy.

BACKGROUND

Health literacy is used frequently in health care and often is confused with patients' reading and comprehension levels.

DESIGN

Walker and Avant's concept analysis method was used.

DATA SOURCE

Cochrane Library, Cumulative Index of Nursing and Health Literature, OVID, PubMed, EBSCO Host databases, and Google Scholar.

REVIEW METHOD

The primary Search terms and MeSH terms used were health literacy, patient education, patient engagement, patient activation, health communication, health promotion, and nursing. Empirical and nonempirical articles published in English were reviewed. Ten systematic literature reviews were included.

RESULTS

A new definition of health literacy is provided based on four components that include: system demands, burdens, and complexities; measurable components, processes and outcomes; the dynamic nature of health literacy; and demonstration of the direct relationship of informed decisions to informed actions. Defining attributes, antecedents, and consequences are identified. Implications for nursing practice, education, and research are given.

CONCLUSIONS

Because health literacy is a dynamic and quickly changing concept, further exploration and evolution of the concept is warranted as empirical research and theoretical literature emerge.

The Design and Testing of the Psychometric Properties of the Person Engagement Index Instrument to Measure a Person's Capacity to Engage in Health Care

BACKGROUND AND PURPOSE

Patient engagement has been considered a powerful tool to improve health outcomes. A composite instrument to measure the factors that impact a person's capacity to engage in his or her health care was an identified gap in the literature. This study developed and tested the psychometric properties of the Person Engagement Index (PEI) instrument.

METHODS

The instrument was tested among 338 medical-surgical inpatients at four health care systems (five facilities), with psychometric evaluation for validity, reliability, and exploratory factor analysis.

RESULTS

Exploratory factor analysis revealed a four-factor solution that accounted for 63.9% of the total variance. Internal consistency results were Cronbach's α = .896 for the overall scale and each subscale: Engagement in Health Care = .885, Technology Use in Health Care = .854, Proactive Approach to Health Care = .728, and Psychosocial Support = .880.

CONCLUSIONS

The results of the PEI study indicate that it is a valid and reliable instrument among the adult medical-surgical population. Further testing of the instrument is recommended among other populations and across the care continuum.

IUHPE Position Statement on Health Literacy: a practical vision for a health literate world

The International Union for Health Promotion and Education (IUHPE) Position Statement on Health Literacy provides an overview of existing evidence and continuing debate on health literacy. Developed by the IUHPE Global Working Group on Health Literacy, including experts from around the globe, the Statement provides a basis for discussion and advocacy, by and with IUHPE, both within the health promotion community, and among stakeholders and partners in health promotion. The Statement offers a detailed introduction to the concept of health literacy, calling for global action to improve health literacy in populations. It positions health literacy as an important and modifiable social determinant of health, that plays a significant role in broadly-based strategies for health promotion. The Statement emphasises the necessity of a systems approach to health literacy, underpinned by global, national, regional and local policies. It summarises key evidence to guide practice and policy development, recognising the importance of continued investment in intervention research, in professional and consumer capacity building, and in the transfer of research findings into frontline health promotion practice. In summary, health literacy is understood as an important cross-cutting issue in health promotion throughout the lifespan, which has practical application in guiding clinical practice, public health interventions and public policy for the advancement of global health.

Assessment Tools for Health Literacy among the General Population: A Systematic Review

Health literacy is an important determinant of health, and is one of the key indicators of a healthy city. Developing and improving methods to measure health literacy is prudent and necessary. This review summarizes the findings of published tools for assessing health literacy among the general population to provide a reference for establishing health literacy assessment tools in the future. In this systematic review, PubMed, Embase, and Web of Science were used to search articles regarding tools for assessing health literacy among the general population published up to 10 January 2018. Two researchers independently conducted literature screening, quality assessment of methodology, and data extraction according to preset inclusion and exclusion criteria. The quality assessment of the research was examined with the use of the specifications of the reporting guidelines for survey research (SURGE). Eleven articles met the inclusion criteria. All included instruments in monitoring the health literacy of the general population were presented through the form of questionnaires. The multistage process of making all the scales generally involved the following steps: item development, pre-testing, and evaluation of readability. However, the specific methods were different. Internal consistency for all the instruments was acceptable but with weak consistency among the subscales for some instruments. Most of the identified instruments derived from the definition of health literacy or were based on existing health literacy theory. Approximately 30% of the performed studies provided no description of the important features specified in the SURGE. This review indicates a trend in the increasing tools for assessing the health literacy of the general population by using multidimensional structures and comprehensive measurement approaches. However, no clear "consensus" was observed in the dimensions of health literacy tools.

Complementary medicine products used in pregnancy and lactation and an examination of the information sources accessed pertaining to maternal health literacy: a systematic review of qualitative studies

BACKGROUND

The prevalence of complementary medicine use in pregnancy and lactation has been increasingly noted internationally. This systematic review aimed to determine the complementary medicine products (CMPs) used in pregnancy and/or lactation for the benefit of the mother, the pregnancy, child and/or the breastfeeding process. Additionally, it aimed to explore the resources women used, and to examine the role of maternal health literacy in this process.

METHODS

Seven databases were comprehensively searched to identify studies published in peer-reviewed journals (1995-2017). Relevant data were extracted and thematic analysis undertaken to identify key themes related to the review objectives.

RESULTS

A total of 4574 articles were identified; 28 qualitative studies met the inclusion criteria. Quantitative studies were removed for a separate, concurrent review. Herbal medicines were the main CMPs identified (n = 21 papers) in the qualitative studies, with a smaller number examining vitamin and mineral supplements together with herbal medicines (n = 3), and micronutrient supplements (n = 3). Shared cultural knowledge and traditions, followed by women elders and health care professionals were the information sources most accessed by women when choosing to use CMPs. Women used CMPs for perceived physical, mental-emotional, spiritual and cultural benefits for their pregnancies, their own health, the health of their unborn or breastfeeding babies, and/or the breastfeeding process. Two over-arching motives were identified: 1) to protect themselves or their babies from adverse events; 2) to facilitate the normal physiological processes of pregnancy, birth and lactation. Decisions to use CMPs were made within the context of their own cultures, reflected in the locus of control regarding decision-making in pregnancy and lactation, and in the health literacy environment. Medical pluralism was very common and women navigated through and between different health care services and systems throughout their pregnancies and breastfeeding journeys.

CONCLUSIONS

Pregnant and breastfeeding women use herbal medicines and micronutrient supplements for a variety of perceived benefits to their babies' and their own holistic health. Women access a range of CMP-related information sources with shared cultural knowledge and women elders the most frequently accessed sources, followed by HCPs. Culture influences maternal health literacy and thus women's health care choices including CMP use.
