Measuring health literacy among immigrants with a phonetic primary language: a case of Korean American women

Implications on self-care behaviors among older Korean immigrants diagnosed with diabetes residing in the United States: a path analytical approach

Background

Diabetes is a prevalent chronic disease. Although self-care is the crucial element in managing diabetes, older Korean immigrants with diabetes face challenges in performing effective self-care related to vulnerability as minority immigrants.

Purpose

This study measures sociodemographics, self-efficacy, social support, diabetes knowledge, and diabetes self-care activities among older Korean immigrants in the United States. This study also aims to demonstrate the direct and indirect effects of the related factors on diabetes self-care activities using a path analysis.

Methods

This study uses a cross-sectional design. Convenience sampling targeted Korean immigrants aged 55 or older using paper and online surveys. Four instruments were used to measure variables: self-efficacy was measured by the General Self-Efficacy scale, diabetes knowledge by the Simplified Diabetes Knowledge Test, social support by the Lubben Social Network Scale-6, and diabetes self-care by the Summary of Diabetes Self-Care Activities questionnaire. Using path analysis, the effects of related factors on self-care activities were analyzed.

Results

190 older Korean immigrants participated, 53.2% female, and 46.8% male. The mean age was 67.2 (SD = 9.9; range, 58-93). A path model shows that sociodemographics (sex, age, education, and years in the United States), diabetes knowledge, self-efficacy, and family support predict diabetes self-care.

Conclusions

The path model demonstrates the effects of sociodemographics, self-efficacy, diabetes knowledge, and social support on diabetes self-care among older Korean immigrants. The findings can help to understand diabetes self-care among the minority ethnic older group and can be used to develop culturally tailored education, counseling, and healthcare services.

Addressing COVID-19 Vaccine Hesitancy and Uptake Among African Immigrants: Lessons from a Community-Based Outreach Program

In 2021, the African Cultural Alliance of North America (ACANA) implemented a community-based vaccine education and outreach program to decrease hesitancy and increase COVID-19 vaccine uptake among African immigrants in Philadelphia. The program had three components: (1) tailored messaging on the benefits of vaccines by trusted community health navigators in familiar languages/dialects, (2) use of educational/tabling events, and (3) establishment of a vaccine clinic in community settings. Using secondary data analysis, in-depth interviews, focus group discussions and a self-administered survey, we explored (i) the impact and effectiveness of the outreach program and extent of vaccine uptake, (ii) African immigrants' beliefs about the COVID-19 pandemic and the vaccine, and (iii) barriers and facilitators of vaccine knowledge, uptake, and hesitancy. Our analysis showed that ACANA's outreach program was effective in addressing several cultural, logistic, and systematic barriers to vaccine uptake. The program distributed 2000 educational/informational flyers, reached 3000 community members via social media campaigns, and an additional 2320 through other person-to-person outreach events. The program was effective and resulted in the vaccination of 1265 community members over the course of the outreach. The impact of this outreach underscores the critical role of community-based organizations in addressing COVID-19 vaccine hesitancy and increasing vaccine uptake in underserved and minority communities. The paper concludes with suggestions and recommendations for using community-based outreach programs to increase COVID-19 vaccine uptake and decrease hesitancy.

Psychometric Properties of General Self-Efficacy (GSE) Scale Korean Version for Older Korean Immigrants with Diabetes: A Cross-Sectional Study in the United States

Patients with diabetes must have self-efficacy to perform necessary self-care tasks. Self-efficacy has been considered as one of the primary motivators on diabetes self-care; therefore, it is essential for health care professionals to assess the self-efficacy of patients with diabetes to provide optimal care. Despite older Korean immigrants having greater difficulty in diabetes management, research on self-efficacy for them is lacking. This study aims to examine the psychometric property of the General Self-Efficacy scale Korean version for older Korean immigrants with diabetes in the United States. In this cross-sectional, methodological study, data were collected using convenience sampling. Cronbach's alpha, exploratory factor analysis, and confirmatory factor analysis were employed to examine the psychometric properties. Cronbach's alpha for the entire GSE scale Korean version is 0.81. The initial Eigenvalues show two factors, coping and confidence; however, the confirmatory factor analysis showed reasonable goodness of fit to the data (χ²(35) = 86.24, p < 0.01), χ²/df ratio = 2.46, AGFI = 0.87, GFI = 0.91, IFI = 0.90, ECVI = 0.74, CFI = 0.89, and RMSEA = 0.093 in the one-factor model. The General Self-Efficacy scale Korean version demonstrated acceptable reliability and validity. It can be used to investigate self-efficacy and to devise culturally tailored diabetes interventions.

Validation of the Short-Test of Functional Health Literacy in Adults for the Samoan Population

BACKGROUND

Health literacy encompasses various levels of communication for an individual, provider, and an organization. Validated and reliable tools have been developed to assess health literacy; however, there is a paucity of tools available to assess health literacy in native languages for indigenous and racial/ethnic minority populations.

OBJECTIVE

This article shares the process taken to translate and evaluate validation and reliability of the Short Test of Functional Health Literacy in Adults for use with the Samoan population.

METHODS

Respondent-driven sampling was used to collect data from 1,543 adults age 45 years and older in American Samoa. A confirmatory factor analysis using a two-factor model for validation was conducted.

KEY RESULTS

The validation results indicated a "good fit" in multiple indices and Cronbach's alpha indicated high internal consistency in both the English and Samoan languages.

CONCLUSIONS

Developing culturally validated and reliable health literacy assessment tools is important to help health care professionals decrease health disparities and address inadequate health literacy in all cultures. [HLRP: Health Literacy Research and Practice. 2022;6(4):e247-e256.] Plain Language Summary: The INSPIRE project studied the Short Test of Functional Health Literacy in Adults (STOFHLA) tested on the American Samoan population age 50 years and older. The results would show if the STOFHLA is a valid tool to measure functional health literacy in American Samoa adults.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

A Descriptive Analysis of Cancer Screening Health Literacy Among Black Women Living with HIV in Baltimore, Maryland

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.

The Relationships Among Health Literacy, Illness Perception, and Diabetes Self-Care in Korean-Speaking Immigrants With Diabetes

Diabetes self-care is explained as an illness-related coping behavior. Health literacy is an important predictor in self-care behaviors. However, little is known about their association with illness perception in Korean immigrants with diabetes. This study aimed to examine the relationships among health literacy, illness perception, and diabetes self-care in Korean-speaking immigrants with diabetes. This cross-sectional study was conducted in 2020. A convenience sample of 52 Korean adults with diabetes in Dallas-Fort Worth areas completed a survey. Data were analyzed using SPSS (version 25) with statistical significance at α < .05. The mean of health literacy was high (11.1, SD = 1.1, ranges 0-12) although risk of type II error with the small sample size. There were no statistically significant associations between health literacy, illness perception, and diabetes self-care. Language barriers are considered a literacy issue, but health literacy and limited English proficiency must be approached differently by health care providers.

Sources of Health Information, Technology Access, and Use Among Non-English-Speaking Immigrant Women: Descriptive Correlational Study

BACKGROUND

As the world is becoming increasingly connected by the World Wide Web, the internet is becoming the main source of health information. With the novel COVID-19 pandemic, ubiquitous use of the internet has changed the daily lives of individuals, from working from home to seeking and meeting with health care providers through web-based sites. Such heavy reliance on internet-based technologies raises concerns regarding the accessibility of the internet for minority populations who are likely to already face barriers when seeking health information.

OBJECTIVE

This study aims to examine the level of technology access and common modes of technology used by Korean American women and to investigate how key psychosocial determinants of health such as age, education, English proficiency, and health literacy are correlated with sources of health information used by Korean American women and by their use of the internet.

METHODS

We used data from a subsample of Korean American women (N=157) who participated in a community-based randomized trial designed to test a health literacy-focused cancer screening intervention. In addition to descriptive statistics to summarize Korean American women's internet access and common modes of technology use, we conducted backward stepwise logistic regression analyses to substantiate the association between the psychosocial determinants of health and internet use.

RESULTS

Approximately two-thirds (103/157, 65.6%) of the sample had access to the internet, and nearly all had access to a mobile phone. The internet was the most commonly used channel to obtain health information 63% (99/157), and 70% (110/157) of the sample used text messaging. Nevertheless, only approximately 38.8% (40/103) of the sample were very confident in using the internet, and only 29.9% (47/157) were very confident in using text messaging. Multivariate analyses revealed that older age (>50 years) was associated with 79% lower odds of using the internet to seek health information (adjusted odds ratio [AOR] 0.21, 95% CI 0.10-0.46). The higher health literacy group (19+ on Rapid Estimate of Adult Literacy in Medicine) had 56% lower odds of using the internet to acquire health information (AOR 0.44, 95% CI 1.13-11.18). Higher education (college+) was associated with both internet use (AOR 4.42, 95% CI 1.88-9.21) and text messaging (AOR 3.42, 95% CI 1.55-7.54). Finally, English proficiency was associated with text messaging (AOR 4.20, 95% CI 1.44-12.24).

CONCLUSIONS

The differences in modes of technology access, use, and confidence by some of the key psychosocial determinants, as observed in our study sample, have important implications when health care teams develop dissemination plans.

Development of a Diabetes-Focused Print Health Literacy Scale Using the Rapid Estimate of Adult Literacy in Medicine Model

BACKGROUND

A diabetes mellitus (DM)-specific health literacy (HL) measure that focuses on both oral and print HL is needed in clinical and research settings.

OBJECTIVE

The present study developed a psychometrically sound DM-specific HL instrument that measures oral and print HL.

METHODS

We developed the measure in three steps. First, we reviewed clinical guidelines and conducted focus groups with experts to generate items. Next, we conducted a psychometric evaluation of the scale in three language versions (English, Spanish, and Korean). Lastly, we identified and removed items with potential cultural bias and duplicate functions to produce shorter versions of the scale, using item response theory (IRT).

KEY RESULTS

We initially developed an 82-item DM-specific oral HL scale using the Rapid Estimate of Adult Literacy in Medicine (DM-REALM) model. To improve the clinical utility of the DM-REALM, we created shorter forms, a 40-item and 20-item version, and evaluated them by using IRT. All DM-REALM versions had high Cronbach alphas (.985, .974, and .945, respectively) and yielded sufficient convergent validity by positive correlations with existing functional HL scale (r = .49, p < .001), education (r = .14, p = .14 to r = .54, p < .001), and DM knowledge (r = .04, p = .70 to r = .36, p < .001). DM-REALM also demonstrated adequate sensitivity as an intervention evaluation tool that captures the changes induced by an intervention.

CONCLUSIONS

All forms of the DM-REALM tool were reliable, valid, and clinically useful measures of HL in the context of DM care. Both researchers and clinicians can use this tool to assess DM-specific HL across multiple racial and ethnic populations. [HLRP: Health Literacy Research and Practice. 2020;4(4):e237-e249.] PLAIN LANGUAGE SUMMARY: This article reported the process and findings of a newly developed health literacy scale for people with diabetes mellitus using three different language versions. Both long and short versions of the scale demonstrated adequate validity and reliability.

Health Literacy, Depression Literacy, and Depression among Older Korean Americans

The purpose of this study was to explore depression and its relationship with background characteristics, health literacy, and depression literacy among Korean Americans (KAs). A cross-sectional survey was conducted among 178 older KAs (age 60≥) in the Washington D.C. metro area in 2016. Three open-ended questions were included to obtain narrative responses for thoughts about depression and its symptoms, and the living situation that might be related to depression. Depression was measured on the Patient Health Questionnaire-9 translated into Korean. The rate of depression was 22.5% among older KAs. No relationship between health literacy and depression was shown. In the regression analysis with covariates, limited English proficiency, less family support, shorter length of U.S. residency, male, and higher depression literacy were significantly associated with higher odds of depression. On narrative questions, only 35% among respondents believed that depression was a mental status. The others described it as environmental or attitude problems such as stress or goals being set too high. Education about depression engaging older KAs immigrants with limited English, and their families are the important health issue in the Korean community.

Familiarity, Navigation, and Comprehension: Key Dimensions of Health Literacy in Pap Test Use among Korean American Women

Health literacy consists of multiple dimensions such as print and oral literacy or numeracy. Different dimensions of health literacy may have more salient impact on certain health behaviors and outcomes. Yet, evidence is limited regarding which dimensions particularly affect cervical cancer screening. The objective of this study was to examine the role of different dimensions of health literacy in cervical cancer screening among Korean American women. We used baseline data obtained from 560 Korean American women in a community-based health literacy-focused intervention study. Backward stepwise logistic regression analysis revealed that familiarity (adjusted odds ratio [AOR] = 1.20, 95% confidence interval [CI] = 1.11-1.31) and navigational health literacy (AOR = 1.10, 95% CI = 1.04-1.16) were associated with lifetime Pap test use and comprehension (AOR = 1.08, 95% CI = 1.02-1.14) with triennial Pap test screening. Prior exposure to healthcare settings and knowing how to navigate the healthcare system were more important than other health literacy dimensions for lifetime Pap test use. Understanding cancer screening-related words was most relevant to triennial Pap test use. In addition to addressing system factors such as insurance and physicians' recommendations, interventions to increase Pap test screening targeted at Korean American women are needed to address certain dimensions of health literacy such as familiarity, navigation, and comprehension.

Validation of the health literacy scale for diabetes as a criterion-referenced test with standard setting procedures

OBJECTIVE

To develop and examine the psychometric properties of the Korean Health Literacy Scale for Diabetes Mellitus (KHLS-DM), and to establish reasonable cutoff scores.

METHODS

Initially, 299 items were generated to measure diabetes-related words, numeracy, and information utilization. Content validity assessment and preliminary tests were conducted. After exploratory factor analysis (EFA) and Rasch analysis, the remaining 65 items were administered to a quota sample of 500 diabetic patients aged 40-74 years. The items were narrowed down to 58 items based on an item fit index. To obtain cutoff scores, Jaeger's method and the Bookmark method were employed.

RESULTS

A confirmatory factor analysis (CFA) was performed, and a three-factor model was supported (χ²/df = 3.891, CFI = 0.92, TLI = 0.91, RMSEA = 0.04). The overall scores ranged from 0 to 58, and two cutoff points were established. The scale exhibited good internal consistency (Cronbach's α = 0.83).

CONCLUSIONS

The KHLS-DM is a reliable and valid measure with cutoff points to classify individuals into three groups (adequate, marginal, and inadequate).

PRACTICE IMPLICATIONS

The standard setting may be useful for researchers to validate health literacy measures in other countries and populations.

Simple screening tools to identify limited health literacy in a low-income patient population

Adults with limited health literacy have difficulty managing chronic conditions, higher hospitalization rates, and more healthcare expenditures. Simple screening tools have been developed, but limited work has evaluated instruments among low-income populations. This study assessed health literacy among primary care patients of a federally qualified health center, and compared a single screening question about perceived difficulty completing medical forms.A cross-sectional survey was administered to English-speaking patients ≥40 years. Both the Newest Vital Sign (NVS), a 6-item questionnaire, and a single-item screening question about perceived difficulty with completing medical forms, assessed health literacy. Logistic regression was used to identify predictors of inadequate health literacy and receiver operator curves compared the NVS and single-item question.Participants (n = 406) were, on average, aged 58.5 years (±11.3), 72.2% female, and identified as Hispanic/Latino (19.2%), non-Hispanic white (31.0%), non-Hispanic black (40.9%), or other (8.9%). Of the 406 participants, 335 (82.5%) completed the NVS. Patients who declined NVS were more likely to be older (P < .001) and male (P = .01). Only 13.7% had adequate health literacy. Older adults, Hispanic and non-Hispanic black patients, patients with missed office visits, and those reporting less confidence completing medical forms were significantly more likely to have inadequate health literacy. Perceived confidence completing medical forms demonstrated low sensitivity but high specificity at multiple thresholds.This is the first investigation to compare the NVS and confidence completing medical forms question. Many patients declined health literacy assessments, but health literacy screening may identify patients who need additional health education and resources.

Decisional balance and self-efficacy mediate the association among provider advice, health literacy and cervical cancer screening

PURPOSE

Health literacy has emerged as a potential determinant of cancer screening, yet limited literature has investigated the pathways which health literacy influences Pap tests among immigrant women who experience a higher incidence of cervical cancer. This study aimed to test a health literacy-focused sociocognitive model which proposes motivational (knowledge, decisional balance) and volitional (self-efficacy) factors mediating the association between health literacy and triennial Pap tests.

METHODS

Using structural equation modeling, we conducted a secondary analysis of baseline data obtained from a randomized controlled trial to promote breast and cervical cancer screenings among 560 Korean American women 21-65 years of age. They were interviewed on demographics such as education and English proficiency, provider advice, health literacy, knowledge of cervical cancer, decisional balance for Pap tests, self-efficacy, and Pap test use.

RESULTS

Higher health literacy predicted high level of knowledge and high decisional balance score, and greater self-efficacy and then only decisional balance and self-efficacy affected Pap tests. High level of knowledge predicted Pap tests through its impact on the decisional balance score. Receiving provider advice both directly and indirectly predicted Pap tests through high level of health literacy, high level of decisional balance and greater self-efficacy.

CONCLUSIONS

Findings from this study suggest possible pathways through which provider advice and health literacy affect Pap tests. Interventions targeting immigrant women with limited English proficiency should consider skill-based approaches such as health literacy training, promoting patient-provider communications and emphasizing decisional balance and self-efficacy as potentially sustainable ways of promoting Pap tests.

Smoking in pregnancy: a cross-sectional study in China

BACKGROUND

Findings on smoking among pregnant women were mostly from high income countries and were rarely from China. This study aimed to estimate the prevalence of smoking and its influencing factors among pregnant women living in China.

METHODS

A cross-sectional analysis was conducted in this study. Data from pregnant women were collected in this study from June to August 2015 from 5 provinces of mainland China. A total of 2345 pregnant women were included in this study, the mean age of the participants was 28.12 years (SD 4.13).

RESULTS

About 82.9% of smoking women quit smoking after they were pregnant. The prevalence of smoking among pregnant women was 3.8%. Among the participants, 40.0, 30.7, 1.8, 29.9, 0.8, 31.4, 31.2, and 26.7% had husbands, fathers-in-law, mothers-in-law, fathers, mothers, colleagues, friends, and relatives, respectively, who were smokers. Compared with pregnant women of basic education level (junior middle school or below), those of the higher education level (undergraduate or above) were at higher risk of smoking (OR, 5.17; 95% CI, 2.00-13.39). Compared with pregnant women from rural areas, urban pregnant women were less likely to be current smokers (OR, 0.55; 95% CI, 0.32-0.94). Compared with pregnant women whose mothers-in-law did not smoke, those whose mothers-in-law smoked were at higher risk of smoking (OR, 4.67; 95% CI, 1.87-11.70). However, compared with pregnant women whose husband did not smoke, those whose husband smoked were not significantly at higher risk of smoking (OR, 1.12; 95% CI, 0.73-1.73).

CONCLUSIONS

Most of smoking women quit smoking after they became pregnant. Tailored intervention programs to reduce smoking in pregnant women should focus on those with higher education level, from rural areas, and pregnant women whose mothers-in-law smoke.

Role of depression in diabetes management in an ethnic minority population: a case of Korean Americans with type 2 diabetes

BACKGROUND

Comorbid depression and diabetes mellitus (DM) compound challenges to disease management such as low health literacy, insufficient access to care, and social or linguistic isolation. Korean Americans (KAs), predominantly first-generation immigrants, suffer from a high prevalence of type 2 DM and depression. Limited research on KAs has prevented the development of effective interventions.

OBJECTIVES

To compare the prevalence of depression in KAs with DM and all Americans with/without DM, and to explore correlates of comorbid DM and depression and strategies to address KAs' DM and depression.

METHODS

KAs' data were from a clinical trial of a community-based self-help intervention to improve KAs' DM and mental health outcomes. National Health and Nutrition Examination Survey data sets enabled comparison. Clinical indicators included hemoglobin A1C, lipid panel, and body mass index. Psychobehavioral indicators included self-efficacy for DM management, quality of life, and depression (Patient Health Questionnaire-9 (PHQ-9)).

RESULTS

More KAs with DM had depression (44.2%) than did all Americans with DM (28.7%) or without DM (20.1%). Significantly more KAs with DM had mild (29.3%) or clinical (14.9%) depression than did Americans with DM (mild, 17.2%; clinical, 11.5%) or without (mild, 13.8%; clinical, 6.3%). One of six KAs with DM (16.9%) thought of suicide or self-harm (Americans with/without =5.0%, 2.8%). The self-help intervention reduced the mean PHQ-9 from 5.4 at baseline to 4.1 at 12 months.

LIMITATIONS

External validity might be limited; KAs' data were from one study site.

CONCLUSIONS

The prevalence of depression and DM among KAs warrants the development of efficacious interventions.

Economic evaluation of a community health worker-led health literacy intervention to promote cancer screening among Korean American women

OBJECTIVE

The study's objectives were to calculate the costs and evaluate the cost-effectiveness of implementing a health literacy-focused intervention to promote breast and cervical cancer screenings among Korean American women overdue for these tests.

METHODS

Researchers estimated the costs of a cluster-randomized controlled trial that evaluated this intervention. Effectiveness was measured as the number of breast or cervical cancer screenings received by women in either the intervention and control arms of the study. Cost-effectiveness was calculated as the incremental cost of each additional screening received by the intervention group.

RESULTS

Comparing the intervention and control group, the incremental cost-effectiveness ratio was estimated to be US$236 per screening, without program development costs.

CONCLUSION

These findings suggest this program, when compared with others, offered a more cost-effective approach for promoting cancer screening. Local health officials could use this information to guide decisions about reducing cancer disparities among recent immigrant women.

Development and psychometric testing of the Health Literacy Index for Female Marriage Immigrants (HLI-FMI) in Korea

This study aimed to develop and examine the psychometric properties of the Health Literacy Index for Female Marriage Immigrants (HLI-FMI). Study participants were 282 women who migrated to Korea from Asian countries to marry and had a mean age of 33.24 years and had immigrated a mean of 5.58 years ago. Data were collected between March 2013 and May 2013. An initial 31 preliminary items were developed based on literature reviews and focus group interviews, including three constructs of health literacy: skills (print, numeracy), tasks (access, understand, appraise, apply), and health contexts (health promotion and disease prevention, health care maintenance and treatment, health system navigation). Exploratory factor analyses of the HLI-FMI yielded 12 items in two factors: Access-Understand Health Literacy (seven items) and Appraise-Apply Health Literacy (five items; Cronbach's alpha = 0.74). Criterion validity was supported through a significant correlation with the Rapid Estimate of Adult Literacy in Medicine-Short Form. Guided by a classical test theory and item response theory, item difficulty and discrimination were within acceptable ranges. HLI-FMI scores were positively associated with participant education and Korean proficiency. The HLI-FMI appears to be the first valid and reliable comprehensive health literacy measure for evaluating health literacy in Korean female marriage immigrants.

A cross-sectional study of the effect of health literacy on diabetes prevention and control among elderly individuals with prediabetes in rural China

OBJECTIVES

This study was designed to examine the effect of health literacy on diabetes prevention and control and risk factors for low diabetes health literacy among elderly individuals with prediabetes in rural areas in China.

DESIGN SETTING AND PARTICIPATES

A cross-sectional survey was conducted among elderly individuals in rural communities in Yiyang City in China. Multi-staged cluster random sampling was used to select 42 areas and 434 individuals with prediabetes who were interviewed using a questionnaire on diabetes health literacy in China.

MAIN OUTCOME MEASURES

Participants were asked for general information (age, gender, marital status, history of hyperglycaemia, family history of diabetes mellitus, presence of other diseases and level of education). Binary logistic regression analysis was used to identify risk factors for poor health literacy concerning diabetes prevention and control among elderly subjects with prediabetes.

RESULTS

The median health literacy score for diabetes prevention and prediabetes control was 10.0 (IQR 7.0-13.0). The level of diabetes health literacy among men was lower than among women (OR 2.831, 95% CI 1.818 to 4.408), and lower among respondents with 1-6 years of education than among those with 6 years or more of education (OR 14.274, 95% CI 5.927 to 34.375). Those with less than 1 year of education had the lowest literacy (OR 31.148, 95% CI 11.661 to 83.204). The level of diabetes health literacy among elderly individuals with prediabetes but no history of hyperglycaemia was lower than among those with a history of hyperglycaemia (OR 2.676, 95% CI 1.101 to 6.504).

CONCLUSIONS

Health literacy concerning diabetes prevention and control among elderly individuals with prediabetes was very low in rural China. Appropriate health education for elderly individuals with low educational levels should be incorporated into diabetes prevention efforts.

Knowledge, perceptions, and decision making about human papillomavirus vaccination among Korean American women: a focus group study

OBJECTIVE

As one of the fastest growing ethnic minority groups in the United States, Korean American (KA) women experience a heightened cervical cancer burden. The advent of the human papillomavirus (HPV) vaccine offers an unprecedented opportunity to eliminate cervical cancer disparities in KA women. However, the uptake of HPV vaccine among KA adolescents remains suboptimal. Hence, we set out to explore knowledge, perceptions, and decision making about HPV vaccination among KA women.

METHODS

We conducted four focus groups of 26 KA women who participated in a community-based, randomized, controlled trial to promote breast and cervical cancer screening. Focus group data were analyzed using qualitative content analysis.

RESULTS

Four main themes emerged from the focus groups: 1) limited awareness and knowledge of HPV vaccine, 2) perceptions and beliefs about HPV vaccination (acceptance, negative perceptions, ambivalence), 3) patterns of decision making about HPV vaccination (hierarchical, peer influenced, autonomous, and collaborative), and 4) promoting HPV education and information sharing in the Korean community.

CONCLUSION

KA women are generally positive toward HPV vaccination, but lack awareness and knowledge about HPV. Culturally tailored HPV education programs based on KA women's decision-making patterns and effective information sharing by trustworthy sources in comfortable environments are suggested strategies to promote HPV vaccination in the KA community. The findings point to the need for a multilevel approach to addressing linguistic, cultural, and system barriers that the recent immigrant community faces in promoting HPV vaccinations. In the development of targeted interventions for KA women, educational strategies and patterns of decision making need to be considered.

The Effect of a Community-Based Self-Help Intervention: Korean Americans With Type 2 Diabetes

INTRODUCTION

Korean Americans are one of the most underserved ethnic/linguistic minority groups owing to cultural and institutional barriers; there is an urgent need for culturally competent diabetes management programs in the Korean American community for those with type 2 diabetes. The purpose of this study was to test the effectiveness of a community-based, culturally tailored, multimodal behavioral intervention program in an ethnic/linguistic minority group with type 2 diabetes.

DESIGN

An RCT with waitlist comparison based on the Predisposing, Reinforcing, and Enabling Constructs in Education/environmental Diagnosis and Evaluation (PRECEDE)-Policy, Regulatory, and Organizational Constructs in Educational and Environmental Development (PROCEED) and self-help models. Data were collected between September 2010 and June 2013 and were analyzed in August-December 2014. Statistical significance was set at p<0.05.

SETTING/PARTICIPANTS

In a naturally occurring community setting, a total of 250 Korean Americans with type 2 diabetes were randomized into an intervention group (n=120) or a control group (n=130).

INTERVENTION

The intervention consisted of key self-management skill-building activities through 12 hours of group education sessions, followed by integrated counseling and behavioral coaching by a team of RNs and community health workers.

MAIN OUTCOME MEASURES

Primary (clinical) outcomes were hemoglobin A1c, glucose, total cholesterol, and low-density lipoprotein at baseline and at 3, 6, 9, and 12 months. Secondary (psychosocial and behavioral) outcomes included diabetes-related quality of life, self-efficacy, adherence to diabetes management regimen, and health literacy.

RESULTS

During the 12-month project, the intervention group demonstrated 1.0%-1.3% (10.9-14.2 mmol/mol) reductions in hemoglobin A1c, whereas the control group achieved reductions of 0.5%-0.7% (5.5-7.7 mmol/mol). The differences between the two groups were statistically significant. The intervention group showed statistically significant improvement in diabetes-related self-efficacy and quality of life when compared with the control group.

CONCLUSIONS

RN/community health worker teams equipped with culturally tailored training can be effective in helping an ethnic/linguistic minority group manage diabetes in the community.

State of the science of health literacy measures: Validity implications for minority populations

OBJECTIVES

To review the evidence supporting the validity of health literacy (HL) measures for ethnic minority populations.

METHODS

PubMed, CINAHL, and PsycINFO databases were searched for HL measures between 1965 and 2013.

RESULTS

A total of 109HL measures were identified; 37 were non-English HL measures and 72 were English language measures. Of the 72 English language measures, 17 did not specify the racial/ethnic characteristic of their sample. Of the remaining 55 measures, 10 (18%) did not include blacks, 30 (55%) did not include Hispanics, and 35 (64%) did not include Asians in their validation sample. When Hispanic and Asian Americans were included, they accounted for small percentages in the overall sample. Between 2005-2013, a growing number of REALM and TOFHLA translations were identified, and new HL measures for specific cultural/linguistic groups within and outside the United States were developed.

CONCLUSIONS

While there are a growing number of new and translated HL measures for minority populations, many existing HL measures have not been properly validated for minority groups.

PRACTICE IMPLICATIONS

HL measures that have not been properly validated for a given population should be piloted before wider use. In addition, improving HL instrument development/validation methods are imperative to increase the validity of these measures for minority populations.

Cross-cultural adaptation and validation of the health literacy assessment tool METER in the Portuguese adult population

OBJECTIVE

We aimed to culturally adapt and validate METER in the Portuguese population, and to define cut-off values for adequate health literacy.

METHODS

We used the standard procedure for the adaptation of the words and surveyed health professionals to select the non-words. The instrument was administered to a total sample of 249 participants and retested in a sub-sample of 45 after three months. Cut-offs were defined using the modified Angoff procedure. Construct validity was assessed through association with educational attainment and health-related occupation.

RESULTS

Exploratory factor analysis revealed two dimensions of the instrument, one for words and another for non-words. METER showed a high degree of internal consistency, and acceptable test-retest reliability. Adequate health literacy was defined as scoring at least 35/40 in words and 18/30 in non-words. Physicians scored higher than any other group, followed by health researchers, researchers from other areas and by people with progressively lower levels of education (p<0.001).

CONCLUSION

We culturally adapted a brief and simple instrument for health literacy assessment, and showed it was valid and reliable.

PRACTICE IMPLICATIONS

The Portuguese version of METER can be used to assess health literacy in Portuguese adults and to explore associations with health outcomes.

Chinese female immigrants english-speaking ability and breast and cervical cancer early detection practices in the New York metropolitan area

BACKGROUND

Breast and cervical cancers are significant causes of mortality and morbidity for Asian women, and poor English-speaking ability is a barrier to cancer prevention practices.

MATERIALS AND METHODS

This project tested relationships among English-speaking ability and early detection practices regarding to breast and cervical cancer among female Chinese immigrants. A descriptive cross-sectional survey was used.

RESULTS

175 female Chinese immigrants completed the survey in the breast cancer prevention section, and 35 of them also completed the cervical cancer prevention section. Some 63% of them had heard about the clinical breast exam (CBE), but only 54% had had a CBE. While 46% of the participants were aware of their need for a Pap smear, only 31% had heard about it and had undergone a pelvic exam.

CONCLUSIONS

English-speaking ability was strongly associated with immigrant women's knowledge of female cancer early detection. Culturally and linguistic issues should be considered as the first step to access immigrant population in designing future education intervention.

Health literacy in Korean immigrants at risk for type 2 diabetes

Rising incidence of type 2 diabetes (DM) in Korean immigrants has highlighted the need for better prevention efforts. Health literacy is an important predictor in the utilization of preventative health measures, however little is known about health literacy in Korean immigrants. This study examined DM risk factors in a sample of 145 at-risk Korean immigrants, their level of health literacy, and associations between health literacy and DM risk factors. Findings indicated a high prevalence of DM risk factors and a low level of health literacy in the sample. Health literacy was correlated with English proficiency, acculturation, and lower waist to hip ratios among all participants, and with lower blood glucose levels among highly acculturated participants. Korean immigrants who are less acculturated may have lower health literacy than those who are more acculturated. Thus, linguistically and culturally sensitive health education should be incorporated into diabetes prevention efforts.

Development and evaluation of the Korean Health Literacy Instrument

The purpose of this study is to develop and validate the Korean Health Literacy Instrument, which measures the capacity to understand and use health-related information and make informed health decisions in Korean adults. In Phase 1, 33 initial items were generated to measure functional, interactive, and critical health literacy with prose, document, and numeracy tasks. These items included content from health promotion, disease management, and health navigation contexts. Content validity assessment was conducted by an expert panel, and 11 items were excluded. In Phase 2, the 22 remaining items were administered to a convenience sample of 292 adults from community and clinical settings. Exploratory factor and item difficulty and discrimination analyses were conducted and four items with low discrimination were deleted. In Phase 3, the remaining 18 items were administered to a convenience sample of 315 adults 40-64 years of age from community and clinical settings. A confirmatory factor analysis was performed to test the construct validity of the instrument. The Korean Health Literacy Instrument has a range of 0 to 18. The mean score in our validation study was 11.98. The instrument exhibited an internal consistency reliability coefficient of 0.82, and a test-retest reliability of 0.89. The instrument is suitable for screening individuals who have limited health literacy skills. Future studies are needed to further define the psychometric properties and predictive validity of the Korean Health Literacy Instrument.

Development and validation of the assessment of health literacy in breast and cervical cancer screening

For many people limited health literacy is a major barrier to effective preventive health behavior such as cancer screening, yet a comprehensive health literacy measure that is specific to breast and cervical cancer screening is not readily available. The purpose of this article is to describe the development and testing of a new instrument to measure health literacy in the context of breast and cervical cancer screening, the Assessment of Health Literacy in Cancer Screening (AHL-C). The AHL-C is based on Baker's conceptualization of health literacy and modeled from the two most popular health literacy tests, the Rapid Estimate of Adult Literacy in Medicine and the Test of Functional Health Literacy in Adults. The AHL-C consists of four subscales; print literacy, numeracy, comprehension, and familiarity. We used baseline data from 560 Korean American immigrant women who participated in a community-based randomized trial designed to test the effect of a health literacy-focused intervention to promote breast and cervical cancer screening. Rigorous psychometric testing supports that the AHL-C is reliable, valid, and significantly correlated with theoretically selected variables. Future research is needed to test the utility of the AHL-C in predicting cancer screening outcomes.

Development and validation of the high blood pressure-focused health literacy scale

OBJECTIVE

While the role of health literacy in chronic disease management is well documented, few intervention studies have been reported. A major barrier to designing and implementing such interventions is the lack of valid health literacy tools. This study developed and tested a novel health literacy scale for individuals with high blood pressure (HBP).

METHODS

A two-step design process was used: In the construction phase, focus group studies and a literature review were conducted to generate a pool of items. The testing phase involved a psychometric evaluation and pilot-testing of the scale on hypertensive Korean Americans (n=386). The end product was a HBP-health literacy scale (HBP-HLS) with two essential domains, print literacy and functional health literacy.

RESULTS

Psychometric testing indicated that the scale was reliable (Kuder-Richardson-20 coefficient=0.98), valid (content validity index ≥0.8), and significantly correlated with theoretically selected variables (education, r=0.67, p<0.01; HBP knowledge, r=0.33, p<0.01).

CONCLUSION

The HBP-HLS demonstrated its utility for evaluating HBP management interventions in the community setting.

PRACTICE IMPLICATIONS

Utilizing the HBP-HLS should be considered as a potential tool for improving health literacy and evaluating intervention studies in the context of HBP management.

Improved pregnancy outcome in refugees and migrants despite low literacy on the Thai-Burmese border: results of three cross-sectional surveys

BACKGROUND

Maternal and infant health has been associated with maternal education level, which is highly associated with literacy. We aimed at estimating literacy rates among reproductive age women attending antenatal clinics in camps for refugees and in migrant clinics in Tak province, north-western Thailand, to determine whether illiteracy had an impact on birth outcomes.

METHODS

Three reading assessments were conducted using an identical method each time, in 1995-97, 2003 and 2008. Midwives chose at random one of four pre-set sentences. Each woman was asked to read aloud and scoring was based on a "pass/fail" system. Pregnancy outcomes were compared with maternal literacy rate.

RESULTS

Overall, 47% (1149/2424) of women were able to read. A significant improvement was observed among migrant (34% in 2003 vs. 46% in 2008, p = 0.01), but not refugee (47% in 1995-97, 49% in 2003, and 51% in 2008) women. Literate women were significantly more likely to be of non-Karen ethnicity, primigravidae, non-smokers, to remain free from malaria during pregnancy and to deliver in a health clinic. Significant improvements in pregnancy outcome (reductions in premature births, low birth weight newborns and neonatal death) between 1995-97 and 2003 were unrelated to literacy.

CONCLUSIONS

Significant reductions in poor pregnancy outcome over time have not been driven by changes in literacy rates, which have remained low. Access to early diagnosis and treatment of malaria in this population, and delivery with skilled birth attendants, despite ongoing low literacy, appears to have played a significant role.
