People who are deaf and hard-of-hearing (DHH) struggle with information marginalization and limited health literacy, challenging their ability to access information on preventing coronavirus disease 2019 (COVID-19). This study assessed the relationship between language preference, health literacy, and COVID-19 information barriers among parents who are DHH in the United States. Data were drawn from a larger study focused on individuals who are DHH who had given birth in the past 10 years. Respondents completed a web-based survey between March 2020 and July 2021. We segmented respondents by language preference [i.e., American Sign Language (ASL), English, or bilingual ASL/English] and used logistic regression models to test the hypothesis that language preference and health literacy were both associated with COVID-19 information marginalization. Of the total sample (N = 417), approximately 17% had limited health literacy, and 22% reported experiencing difficulty accessing information about COVID-19. In adjusted analyses, respondents with limited health literacy ([adjusted odds ratio] aOR = 2.245) and Hispanic ethnicity (aOR = 2.149) had higher risk of reporting information access barriers. There was no association between language preference and reporting COVID-19 information barriers. However, individuals who are DHH with limited health literacy were at higher risk of experiencing information marginalization during the ongoing COVID-19 pandemic, highlighting the need for tailored information based on access needs.

Background: Black women living with HIV (WLH) have the highest HIV infection rate, cervical cancer mortality, and the lowest cancer screening use compared to other groups. However, there is a gap in knowledge about cancer screening health literacy in the Black WLH population.

Objective: The purpose of this study was to assess the level of cancer screening health literacy, and to identify factors associated with health literacy among Black WLH.

Methods: This study used baseline data from a community-based randomized controlled trial for a health literacy intervention called CHECC-uP (community-based health literacy intervention for cancer control). We recruited a convenience sample of Black WLH (N = 123) who understand English and had no Pap testing in the prior 12 months. The outcome was cancer screening health literacy measured with a validated health literacy tool-Assessment of Health Literacy in Cancer Screening. Predictors included age, marital status, education, income, and insurance type. The association between cancer screening health literacy and predictors was assessed with multivariate logistic regression.

Key results: Almost one-half (49.6%) of study participants had a reading level at or below sixth grade. Older age (adjusted odds ratio [aOR] 1.05) and higher educational levels (aOR 5.13) were significantly associated with higher cancer screening health literacy among our sample of Black WLH in bivariate and multivariate analyses.

Conclusions: Educational materials and other approaches to empower patients should be tested with patients who have low health literacy to ensure efficacy. [HLRP: Health Literacy Research and Practice. 2022;6(3):e175-e181.] Plain Language Summary: Using a cancer screening health literacy tool, we found that about one-half of the Black WLH in the study had a reading level at or below sixth grade. Age and education level were related to their reading levels among the women. Researcher and clinicians need to test educational materials and other approaches with patients who have low health literacy to make sure they work.

Background: Heart failure is a costly condition with high morbidity and mortality rates in low- and middle-income countries. Nonadherence to prescribed therapies can lead to severe problems such as poorer health outcomes, higher health care expenditures, increased hospitalizations, and even higher mortality rates in patients with advanced heart disease.

Objective: The aim of the present study is to investigate medication adherence and the association between medication adherence and health literacy in Iranian patients with heart failure.

Methods: This study was conducted in the heart failure outpatient clinic of Shahid Rajaee Cardiovascular, Medical, and Research Center in Tehran, Iran. Medical records and validated questionnaires were used to collect the necessary information on the survey variables, including sociodemographic characteristics, medication adherence, and health literacy, for a total of 250 patients with heart failure. Stepwise logistic regression analysis was performed to identify the variables that independently and significantly predicted medication nonadherence.

Key results: The results showed that most patients with heart failure had low medication adherence. Some factors, including gender, health literacy, and duration of illness, were associated with adherence. The study results showed a positive association between higher health literacy and better medication adherence.

Conclusion: In view of the results, further studies on heart failure are needed to investigate other factors related to medication adherence and health literacy level to achieve better disease management and improve patients' treatment adherence. [HLRP: Health Literacy Research and Practice. 2022;6(3):e191-e199.] Plain Language Summary: This study investigated the relationship between medication adherence and health literacy in Iranian patients with heart failure. The results showed that most patients had inadequate health literacy. Moreover, it showed a significant and positive relationship between health literacy and medication adherence.

Background: Health literacy research and practice are constantly evolving. Recent inquiry has highlighted the burdensome literacy demands faced by people with serious mental illness (SMI). Systems, organizational operations, and structures can play a role in decreasing literacy demand, thereby reducing unnecessary challenges for people with SMI. Brief Description of Activity: An organizational health literacy assessment was conducted to explore literacy demands in one mental health shelter and revealed best practice action steps for improving the literacy environment.

Implementation: The assessment included an exploration of the shelter environment using The Health Literacy Environment Activity Packet, First Impressions & Walking Interview, and a commonly used shelter document using the Simple Measure of Gobbledygook (SMOG), Suitability Assessment of Materials (SAM), and Centers for Disease Control and Prevention (CDC) Index.

Results: The literacy demands of the shelter environment and a frequently used document exceeded the literacy skills of people with SMI. Environment assessment revealed environmental facilitators (e.g., welcoming atmosphere) and barriers (e.g., unclear signage). Document assessment also revealed facilitating factors and barriers. SMOG scores ranged from 11.25 to 11.80 (median: 11.38), meaning 11th to 12th grade-level reading skills are required to understand, use, and take action on the document's content. A SAM score of 50% (adequate) and a CDC Index score of 42.1 (revise and improve) reveal materials contain both facilitating factors (e.g., chunked sections) and barriers (e.g., jargon, mismatched graphics) to use.

Lessons learned: The mismatch between system demands and the literacy skills of people with SMI is more profound than that of the general United States population. Organizational health literacy assessments are achievable and useful for both immediate and long-term action aimed at understanding and improving the organizational health literacy of mental health spaces. Further work is needed to explore the role of behavioral health services in addressing the institutional and programmatic literacy demands that inhibit treatment and recovery. [HLRP: Health Literacy Research and Practice. 2022;6(3):e167-e174.] Plain Language Summary: An organizational health literacy assessment reveals how system demands can be changed to better serve intended users. Engaging in mental health, recovery, and treatment services requires complex literacy skills. Generally, the U.S. adult population does not have the skills to meet such demands, and this is especially true among public mental health service users.

Background: Online health education and other electronic health improvement strategies are developing rapidly, highlighting the growing need for valid scales to assess health literacy (HL). One comprehensive HL scale is the Health Literacy Questionnaire (HLQ), but little is known about its measurement properties in online health education cohorts.

Objective: The purpose of this study was to determine if the multidimensional HLQ is an appropriate tool to measure HL in a cohort of Understanding Multiple Sclerosis (MS) online course enrollees.

Methods: Participants who enrolled in the first two open enrollments of the Understanding MS online course completed the HLQ (N = 1,182) in an online survey prior to beginning course materials. We used Rasch analysis to assess the measurement properties of the HLQ.

Key results: The nine Domains of the HLQ each had ordered category function and a good fit with the Rasch model. Each domain was one-dimensional and exhibited good internal consistency and reliability. None of the 44 individual items of the HLQ demonstrated item bias or local dependency. However, while the overall fit was good, few measurement gaps were identified in this cohort for participants in each of the nine Domains, meaning that the HLQ may have low measurement precision in some participants.

Conclusion: Our analysis of the HLQ indicated acceptable measurement properties in a cohort of Understanding MS online course enrollees. Although reliable information on nine separate constructs of HL was obtainable in the current study indicating that the HLQ can be used in similar cohorts, its limitations must be also considered. [HLRP: Health Literacy Research and Practice. 2022;6(3):e200-e212.] Plain Language Summary: In this study, we have shown that the HLQ is suitable for measuring HL in an online public health educational platforms for chronic diseases including multiple sclerosis. This finding adds to the evidence that the HLQ can be widely used in measuring HL in different settings, populations, and health educational platforms.

Background: Recognizing that a deficit of reading and numeracy skills is associated with poorer oral health, contemporary researchers have identified additional components as important attributes of oral health literacy (OHL). So, the use of comprehensive functional OHL tools is crucial. The Oral Health Literacy-Adults Questionnaire (OHL-AQ) evaluates reading comprehension, numeracy, listening and decision-making skills.

Objective: Describe the validation process of the OHL-AQ Brazilian version (BOHL-AQ).

Methods: The cross-culturally adapted version, BOHL-AQ, was applied to 180 employees age 18 to 71 years (mean = 37.2; standard deviation [SD] = 11.7) from a private university located in the Southeast of Brazil. Psychometric properties were evaluated through the analysis of internal consistency (Cronbach's alpha), reproducibility (test-retest), convergent validity (BREALD-30; education level), discriminant validity (family income; dental services), predictive validity (self-perception; literacy questions) and construct validity (Exploratory Factor Analysis). Confirmatory Factor Analysis (CFA) evaluated the dimensionality of the BOHL-AQ, with Promax method for rotation. Data were analyzed using SPSS Statistics software and the Mplus program.

Key results: BOHL-AQ mean score = 11.84 (SD = 3.1); administration mean time = 8 minutes (SD = 1.6); good internal reliability (Cronbach's alpha = 0.73) and excellent reproducibility (kappa = 0.89; intraclass correlation coefficient = 0.97). Preliminary tests showed that data were suitable for PCA (Kayser-Meyer-Olkin measure = 0.75; Barlett's Test of Sphericity significant [p < .001]). CFA showed that the instrument had a four-factor solution with excellent model fit estimates (χ² = 636.587154.16, p value = .00117, Comparative Fit Index = 0.9787, Tucker Lewis index = 0.97, and Root Mean Square Error of the Approximation = 0.03). BOHL-AQ high scores significantly correlated to high education level, dental visit within the last year and for preventive reason, more independence and self-confidence on reading and filling out health forms, and better oral health self-perception (p < .05).

Conclusions: The BOHL-AQ showed to be a fast and reliable instrument to assess a comprehensive functional OHL at Brazilian community and clinical settings. [HLRP: Health Literacy Research and Practice. 2022;6(3):e224-e231.] Plain Language Summary: Recognizing the need of advancing knowledge related to OHL, this study aimed to describe the validation process of the BOHL-AQ. Cross-cultural adaptation and psychometric properties evaluation presented satisfactory results. The BOHL-AQ proved to be a fast and valid instrument to measure comprehensive functional OHL in the Brazilian context.

Background: How individuals perceive their health literacy may differ based on demographic and individual characteristics.

Objective: The purpose of this study was to understand the dispersion of health literacy across demographics in the state of Georgia in 2021 and to determine which factors influence health literacy.

Methods: Study participants were age 18 years and older and completed an on-line Health Literacy Questionnaire (N = 520). The participant pool was stratified to mirror state-wide demographics of geography and race. Results were further collapsed into composite scales reflecting basic, communicative, and critical health literacy. Descriptive statistics, bivariate Pearson's correlations, and multiple regression analyses were used. A two-step cluster analysis was performed with the nine health literacy scales.

Key results: Rural county and no health insurance were negatively related to all three composite scales (rs = .093-.254, ps < .05). Demographic predictors accounted for 6.7% of the variance in basic (F[6, 439] = 5.287, p < .001), 10% in communicative (F[6, 438] = 8.154, p < .001), and 6% for critical (F[6, 439] = 4.675, p < .0010. In all scales, health insurance status was the strongest primary unique predictor (βs = .236, .295, .181, ps <.05, respectively). In a two-step cluster analysis only health insurance status differentiated the health literacy level clusters (X²(3) = 9.43, 34.51, ps = 024, <.001 respectively).

Conclusion: Lacking health insurance is the most consistent and largest contributor to low health literacy across the state of Georgia; population demographics are not. Health literacy policies and practices should be developed for universal application and not focus on specific populations. [HLRP: Health Literacy Research and Practice. 2022;6(3):e182-e190.] Plain Language Summary: In this study, demographics that are usually associated with low health literacy like age, sex, race, educational attainment, and type of county (rural or urban) were not associated with; the only significant factor was lack of health insurance. This relationship strengthens the case for universal health literacy precautions that go beyond population demographics.

Health literacy is limited among most of the German population. Among vulnerable groups, including people with a migration history, it is necessary to provide support. Thus, the public health department of the city of Frankfurt am Main initiated a project called communal health guides intercultural [Kommunale Gesundheitslotsen interkulturell] where health guides are trained to strengthen the health literacy of people with a migration background as well as of people with poor socioeconomic living conditions. Health guides are trained on specific health topics to pass on their knowledge as multipliers in different target groups. We are introducing two new modules complementing the existing health guide project from conceptualization to evaluation. The first module aims to strengthen health literacy among parents of children younger than age 10 years and the second module addresses inhabitants of community accommodations and aims to improve health communication and information, currently focusing on coronavirus disease 2019 and vaccinations. Another aim of the two modules is to find out the specific information needs of the target populations. The newly added modules aim to reduce health inequities for all citizens of Frankfurt am Main. [HLRP: Health Literacy Research and Practice. 2022;6(3):e239-e246.] Plain Language Summary: Health literacy is often limited among the German population. Especially for socially disadvantaged groups, the public health department of the city of Frankfurt am Main would like to provide support. A project called Communal Health Guides Intercultural was initiated. Health leaders are trained to strengthen the health literacy of people who are socially disadvantaged. This project consists of two modules. One module is aimed at parents of children younger than age 10 years; the other module is aimed at residents in community accommodation. The project aims to reduce health inequities.

Background: Health services hold a critical role in mitigating the effect of health literacy challenges. Several tools and approaches have been developed to support health organizations in responding to their target population's health literacy needs. One of these is the OS! approach, which is an adapted and less rigorous version of the Australian Organizational health literacy responsiveness tool (Org-HLR). In this study, we aimed to report on our initial testing of the OS! approach in two Danish health care settings.

Brief description: The OS! aim to prompt and support the development of local organizational health literacy improvement ideas. The process consists of three consecutive workshops focusing on reflection, self-evaluation, and prioritization. For each workshop tools are provided to support implementation.

Implementation: The OS! approach was tested in two Danish municipal health centers (Tårnby Health Centre and Frederiksberg Health Centre), where both staff members and leaders took part in the processes (N = 62 and N = 84). In Tårnby, the process was closely facilitated by the research team, while local managers was in charge of the implementation in Frederiksberg.

Results: In both settings, the process succeeded in identifying a list of relevant prioritized action ideas aimed at improving local health literacy responsiveness. In both instances, leaders were able to integrate some of these ideas in action plans for the organizations nearby future.

Lessons learned: We found the OS! approach effective in its aim to identify health literacy responsiveness improvement ideas and based on our experience also less arduous to implement than the Org-HLR. We also learned that good implementation of the OS! approach depends strongly on careful facilitation including thorough introduction of the concepts of health literacy, openness, and creativity in relation to local adaptions within the overall framework of the approach, and the consolidation of consistent leader support throughout the organization. [HLRP: Health Literacy Research and Practice. 2022;6(3):e232-e238.] Plain Language Summary: This study describes the initial testing of the OS!

Approach: The OS! approach is based on the Australian methodology "Org-HLR" and use a participatory approach to prompt and support the identification of local health literacy responsiveness improvement ideas in health care organizations. The article provides valuable experiences regarding local development of organizational health literacy in practice.

Background: Health literacy has often been described as an important precondition for good health decisions, healthy behaviors, and health. However, reviews reveal low evidence for intervention effectiveness through health literacy. This result calls for more investigations to be done in the pathway from health literacy to health, considering intermediate outcomes of health literacy.

Objective: This study explores an important immediate objective of health literacy, namely the decision-making ability (DMA) regarding health issues. The study's hypothesis claims the DMA to be an important mediator between health literacy and health outcomes. Furthermore, the study assumes that the effect of the DMA on different health outcomes is not only contingent on health literacy but also on contextual factors. To test the above hypotheses, six different health literacy dimensions and four health outcomes have been analyzed.

Methods: Cross-sectional data from the Young Adult Survey Switzerland was used for mediation analyses (N = 4, 569, age, 18 to 25 years, all male). Multiple regression and KHB (Karlson, Holm, and Breen) decomposition analyses were applied to estimate mediation effects between health literacy and health outcomes.

Key results: Five of six health literacy dimensions explained the DMA in a linear regression model. The coefficients of the DMA explaining health outcomes were substantially reduced when health literacy items were included into the models (6.1%-20.3%). Furthermore, the associations between health literacy and the health outcomes were fully explained by contextual factors, except in the mental health model.

Conclusions: The results support the hypothesis that higher health literacy levels do not necessarily lead to better health directly. Rather, health literacy is just one of multiple factors contributing to a higher DMA and, further, to favorable health outcomes. The results of this study call for more investigations in the health decision-making process and the role of contextual factors. [HLRP: Health Literacy Research and Practice. 2022;6(3):e213-e223.] Plain Language Summary: The study investigated the ability to make good health decisions while considering health literacy. The results support the intermediate function of the decision-making ability on the path to favorable health outcomes. Furthermore, it is found that the DMA as well as health literacy are highly contingent on contextual factors. The results shed light into the complex decision-making process regarding health issues.
