Effects of health literacy skills,educational attainment,and level of melanoma risk on responses to personalized genomic testing

ObjectiveFew studies have examined how health literacy impacts responses to genetic information.MethodsWe examined this issue among 145 English or Spanish-speaking adult primary care patients enrolled in a trial that offered testing for MC1R gene variants that confer moderately increased melanoma risk. We investigated whether health literacy skills, educational attainment, or melanoma risk were related to short-term cognitive and affective responses to genetic test results.ResultsOn average, participants found the test results to be highly believable and clear, with low levels of negative emotional responses and moderate levels of positive responses. In adjusted models, health literacy skills were significantly inversely associated with confusion (OR = 0.75, 95 % CI = 0.58, 0.96); those with higher education thought significantly less about their test results (β = ?0.66), were less hopeful (β = ?0.89), and had lower distress (β = ?1.15). We also observed a significant interaction (p < .001) between health literacy and melanoma risk in affecting the frequency of thoughts about test results.ConclusionThe findings indicate that health literacy skills may affect to what extent individuals elaborate cognitively on genetic information.Practice implicationsPatients with lower health literacy skills or education may need support in understanding genetic test results.     

Health literacy as a predictor of emergency department visits and self-rated health among Chinese immigrants: findings from an Australian survey

ObjectivesOur objectives were to examine health literacy among first-generation Chinese immigrants living in Australia, identifying health literacy domains associated with emergency department (ED) visits and self-rated health (SRH).MethodsChinese immigrants (n = 362, mean age = 59) were recruited from communities across New South Wales and surveyed for health literacy, ED visits in the past 12 months, and SRH using the Health Literacy Questionnaire (simplified Chinese version).ResultsMore than 70% of participants experienced health literacy difficulties. Health literacy was significantly lower among the following participants: older, migration at older age, recent immigrants, and those without university level education or proficient English.ED visits were independently associated with the health literacy domains lacking ‘social support for health’ (OR: 1.80; p = .031) and ‘ability to appraise health information’ (OR: 2.22; p = .005). Poor SRH was associated with the health literacy domains ‘insufficient health information’ (OR: 1.81; p = .025), ‘inactively managing health’ (OR: 1.72; p = .048), and ‘lacking ability to appraise health information’ (OR: 1.70; p = .048).ConclusionsInadequate health literacy was identified in the majority of first-generation Chinese immigrants and it had significantly association with higher prevalence of ED use and poorer SRH.Practice implicationsEarly screening and support for health literacy is critical in Chinese immigrants.     

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

ObjectivesTo compare functional health literacy (HL) levels in three immigrant groups to those of the German- and Italian-speaking non-immigrant population in Switzerland. Moreover, to investigate whether language-independent, respectively language-dependent, functional HL and variables of acculturation were associated with self-reported health status among immigrants.MethodsLanguage-independent HL was assessed with the Short Test of Functional Health Literacy (S-TOFHLA) in the respective native languages. Language-dependent HL was measured using Brief Health Literacy Screeners (BHLS) asking about participants’ confidence in understanding medical information in the language of the host country. Measures of acculturation included length of stay and age when taking residency in Switzerland.ResultsIn particular Albanian- and Portuguese-speaking immigrants had lower levels of functional HL. In unadjusted analysis “age when taking residency in Switzerland” was associated with the BHLS. Adjusted analysis showed that the BHLS were significantly associated with self-reported health among all immigrant groups (p ≤ 0.01).ConclusionsFunctional HL that is dependent on understanding of medical information in the language of the new host country is a better predictor for self-reported health status among immigrants than language-independent HL.Practice implicationsIn the clinical setting limited functional HL might be a significant obstacle to successful disease treatment and prevention in immigrants.     

Assessment of skin cancer precision prevention materials among Hispanics in Florida and Puerto Rico

ObjectiveTo assess Hispanic participants’ ratings of intervention materials and examine differences by language preference.MethodsParticipants on a skin cancer prevention trial were randomized to receive generic (n = 457) or precision prevention materials conveying average (n = 195) or higher genetic risk (n = 268) based on MC1R genotype. Three months after receiving either English or Spanish language prevention materials, participants reported amount read, believability and clarity of materials, and intention to change preventive behavior.ResultsParticipants reported high levels on all four outcomes, but the precision prevention groups noted lower clarity than the generic group (p = 3.2 ×10^-6). Participants preferring Spanish provided consistently higher scores than those preferring English. Among English-preferring participants, those in the precision prevention groups scored lower on all measures than those in the generic group.ConclusionsSkin cancer prevention materials were well-received by Hispanic participants. Higher scores among participants preferring Spanish may indicate acquiescence bias, or that translated prevention materials met their linguistic needs. Participants in the precision prevention groups with English language preference may have challenges in the uptake of genetic risk results.Practice ImplicationsAvailability of Spanish materials may have facilitated higher scores. Additional strategies should be explored to optimize participants’ believability and clarity of precision prevention materials.     

eHealth Literacy and Web 2.0 Health Information Seeking Behaviors Among Baby Boomers and Older Adults

BackgroundBaby boomers and older adults, a subset of the population at high risk for chronic disease, social isolation, and poor health outcomes, are increasingly utilizing the Internet and social media (Web 2.0) to locate and evaluate health information. However, among these older populations, little is known about what factors influence their eHealth literacy and use of Web 2.0 for health information.ObjectiveThe intent of the study was to explore the extent to which sociodemographic, social determinants, and electronic device use influences eHealth literacy and use of Web 2.0 for health information among baby boomers and older adults.MethodsA random sample of baby boomers and older adults (n=283, mean 67.46 years, SD 9.98) participated in a cross-sectional, telephone survey that included the eHealth literacy scale (eHEALS) and items from the Health Information National Trends Survey (HINTS) assessing electronic device use and use of Web 2.0 for health information. An independent samples t test compared eHealth literacy among users and non-users of Web 2.0 for health information. Multiple linear and logistic regression analyses were conducted to determine associations between sociodemographic, social determinants, and electronic device use on self-reported eHealth literacy and use of Web 2.0 for seeking and sharing health information.ResultsAlmost 90% of older Web 2.0 users (90/101, 89.1%) reported using popular Web 2.0 websites, such as Facebook and Twitter, to find and share health information. Respondents reporting use of Web 2.0 reported greater eHealth literacy (mean 30.38, SD 5.45, n=101) than those who did not use Web 2.0 (mean 28.31, SD 5.79, n=182), t _217.60=−2.98, P=.003. Younger age (b=−0.10), more education (b=0.48), and use of more electronic devices (b=1.26) were significantly associated with greater eHealth literacy (R ² =.17, R ²adj =.14, F_9,229=5.277, P<.001). Women were nearly three times more likely than men to use Web 2.0 for health information (OR 2.63, Wald= 8.09, df=1, P=.004). Finally, more education predicted greater use of Web 2.0 for health information, with college graduates (OR 2.57, Wald= 3.86, df =1, P=.049) and post graduates (OR 7.105, Wald= 4.278, df=1, P=.04) nearly 2 to 7 times more likely than non-high school graduates to use Web 2.0 for health information.ConclusionsBeing younger and possessing more education was associated with greater eHealth literacy among baby boomers and older adults. Females and those highly educated, particularly at the post graduate level, reported greater use of Web 2.0 for health information. More in-depth surveys and interviews among more diverse groups of baby boomers and older adult populations will likely yield a better understanding regarding how current Web-based health information seeking and sharing behaviors influence health-related decision making.     

Health literacy in the eHealth era: A systematic review of the literature

ObjectivesThis study aimed to identify studies on online health service use by people with limited health literacy, as the findings could provide insights into how health literacy has been, and should be, addressed in the eHealth era.MethodsTo identify the relevant literature published since 2010, we performed four rounds of selection—database selection, keyword search, screening of the titles and abstracts, and screening of full texts. This process produced a final of 74 publications.ResultsThe themes addressed in the 74 publications fell into five categories: evaluation of health-related content, development and evaluation of eHealth services, development and evaluation of health literacy measurement tools, interventions to improve health literacy, and online health information seeking behavior.ConclusionBarriers to access to and use of online health information can result from the readability of content and poor usability of eHealth services. We need new health literacy screening tools to identify skills for adequate use of eHealth services. Mobile apps hold great potential for eHealth and mHealth services tailored to people with low health literacy.Practice implicationsEfforts should be made to make eHealth services easily accessible to low-literacy individuals and to enhance individual health literacy through educational programs.     

“It’s Got to Be on This Page”: Age and Cognitive Style in a Study of Online Health Information Seeking

BackgroundThe extensive availability of online health information offers the public opportunities to become independently informed about their care, but what affects the successful retrieval and understanding of accurate and detailed information? We have limited knowledge about the ways individuals use the Internet and the personal characteristics that affect online health literacy.ObjectiveThis study examined the extent to which age and cognitive style predicted success in searching for online health information, controlling for differences in education, daily Internet use, and general health literacy.MethodsThe Online Health Study (OHS) was conducted at Johns Hopkins School of Public Health and Stanford University School of Medicine from April 2009 to June 2010. The OHS was designed to explore the factors associated with success in obtaining health information across different age groups. A total of 346 men and women aged 35 years and older of diverse racial and ethnic backgrounds participated in the study. Participants were evaluated for success in searching online for answers to health-related tasks/questions on nutrition, cancer, alternative medicine, vaccinations, medical equipment, and genetic testing.ResultsCognitive style, in terms of context sensitivity, was associated with less success in obtaining online health information, with tasks involving visual judgment most affected. In addition, better health literacy was positively associated with overall success in online health seeking, specifically for tasks requiring prior health knowledge. The oldest searchers were disadvantaged even after controlling for education, Internet use, general health literacy, and cognitive style, especially when spatial tasks such as mapping were involved.ConclusionsThe increasing availability of online health information provides opportunities to improve patient education and knowledge, but effective use of these resources depends on online health literacy. Greater support for those who are in the oldest cohorts and for design of interfaces that support users with different cognitive styles may be required in an age of shared medical decision making.     

Performance of the English and Spanish S-TOFHLA among publicly insured Medicaid and Medicare patients

The objective of this study was to analyze the psychometric properties of the English and Spanish S-TOFHLA for three patient populations of interest. Despite being widely used, little is written about psychometric properties of the S-TOFHLA, particularly the Spanish version. Participants were Medicaid and Medicare patients: 936 non-Hispanic and 368 Hispanic patients completed the English S-TOFHLA; 1066 Hispanics completed the Spanish S-TOFHLA. Validity of both versions of the S-TOFHLA was supported by strong positive relationships with education and inverse relationships with age. Significant differences between scores for men and women remained after adjusting for level of education. Score differences occurred across numerous items. More research is needed on the S-TOFHLA and other health literacy instruments to determine why women score differently than men. Variability in literacy skills within subgroups of patients highlights the importance of healthcare providers being sensitive to patients' literacy levels in both spoken and written communications.     

Tools to Measure Health Literacy among US African Americans and Hispanics/Latinos with Type 2 Diabetes: A Scoping Review of the Literature

ObjectiveTo provide an overview of the health literacy tools that have been validated in samples of African Americans and Hispanics/Latinos with type 2 diabetes, growing segments of the US population.MethodsFollowing PRISMA guidelines, three electronic databases were searched. The following inclusion criteria were used: peer-reviewed research; examined validity of a health literacy tool; and included US African American and/or Hispanic/Latino adults with type 2 diabetes.ResultsSixteen studies were selected; none exclusively included African Americans while 3 exclusively included Hispanics/Latinos in the sample. Seventeen health literacy tools were identified. Among African Americans, 2 health literacy screeners, 2 diabetes knowledge, and 3 numeracy tools have been validated. Among Hispanics/Latinos, 1 health literacy screener, 1 diabetes knowledge, and 1 numeracy tool have been validated. However, cross-cultural adaptation principles were rarely considered in the development and validation of these tools.ConclusionIn those with type 2 diabetes, future studies should investigate the validity of health literacy screeners among English-speaking Hispanics/Latinos and general health literacy tools among African Americans and Hispanics/Latinos. Evidence on the validity of diabetes knowledge and numeracy tools was mixed across studies.Practice implicationsFindings can inform the selection of culturally-appropriate health literacy tools in clinical and research settings.     

Supporting health literacy using an interactive app for symptom management during radiotherapy for prostate cancer

ObjectivePatients’ ability to self-monitor symptoms and engage in self-care activities is dependent upon their level of health literacy. Health literacy and self-care ability was compared in men with prostate cancer undergoing radiotherapy that used an app for symptom management with a control group.MethodsIncluded were an intervention group (n = 66), who used an app for symptom reporting and support for self-care, and a control group (n = 64). Outcomes were Functional Health Literacy, Communicative and Critical Health Literacy and Appraisal of Self-Care Agency (ASA-A).ResultsThe intervention group had improved regarding “ability to select information needed from a variety of information sources” (p = .020), “ability to determine the information credible” (p = .041), and “being able to plan and decide what to do to improve health” (p = .004). No inter-group difference was found for ASA-A.ConclusionsWith the support of an app for reporting and managing symptoms, important advanced health literacy skills of selecting, determining, and judging information credible may improve.Practice implicationsPatients undergoing treatment for prostate cancer may benefit from an individualized approach, such as an app, for communication with health care providers and as a source of health information to make decisions about their own health.     

Entertainment or Health? Exploring the Internet Usage Patterns of the Urban Poor: A Secondary Analysis of a Randomized Controlled Trial

BackgroundImportant gaps remain in our knowledge of how individuals from low socioeconomic position (SEP) use the Internet for resources and in understanding the full range of activities they perform online. Although self-report data indicate that low SEP individuals use the Internet less than high SEP people for health information and for other beneficial capital-enhancing activities, these results may not provide an accurate overall view of online use.ObjectiveThe aim of this study was to determine the ways in which low SEP individuals use the Internet, including for entertainment, social networking, and capital-enhancing functions, and how they are associated with health information seeking.MethodsDetailed Web tracking data were collected from 118 low SEP individuals who participated in the intervention group of a randomized controlled trial that provided Internet access. Websites were grouped by topic, including categories of capital-enhancing websites that provided access to resources and information. Different types of online activities were summed into an Internet use index. Single and multiple negative binomial regression models were fitted with the Internet use index as the predictor and health information seeking as the outcome. Next, models were fitted with low, medium, and high Web usage in capital-enhancing, entertainment, and social network categories to determine their associations with health information seeking.ResultsParticipants used the Web for diverse purposes, with 63.6% (75/118) accessing the Internet for all defined types of Internet use. Each additional category of Internet use was associated with 2.12 times the rate of health information seeking (95% CI 1.84-2.44, P<.001). Higher use of each type of capital-enhancing information was associated with higher rates of health information seeking, with high uses of government (incident rate ratio [IRR] 8.90, 95% CI 4.82-16.42, P<.001) and news (IRR 11.36, 95% CI 6.21-20.79, P<.001) websites associated with the highest rates of health information seeking compared to their lowest use categories. High entertainment website use (IRR 3.91, 95% CI 2.07-7.37, P<.001) and high social network use (IRR 2.06, 95% CI 1.08-3.92, P=.03) were also associated with higher health information seeking.ConclusionsThese data clearly show that familiarity and skills in using the Internet enhance the capacity to use it for diverse purposes, including health and to increase capital, and that Internet usage for specific activities is not a zero sum game. Using it for one type of topic, such as entertainment, does not detract from using it for other purposes. Findings may inform ways to engage low SEP groups with Internet resources.     

Validation of the Spanish and English versions of the asthma portion of the Brief Pediatric Asthma Screen Plus among Hispanics.

BACKGROUND: The health and health care needs of non-English-speaking Hispanic families with children are poorly understood, in part because they are often excluded from research owing to language barriers. Instruments that are valid in English and Spanish are necessary to accurately evaluate the magnitude of asthma prevalence and morbidity among Hispanics. OBJECTIVE: To establish the sensitivity and specificity of the English and Spanish versions of the asthma portion of the Brief Pediatric Asthma Screen Plus (BPAS+) in a low-income Hispanic population. METHODS: The validation sample consisted of 145 children whose parents completed the BPAS+ in Spanish and 78 whose parents completed it in English. Bilingual clinicians conducted the examinations on which the clinical assessments were based. We compared the BPAS+ results with the clinical assessment findings to determine the sensitivity and specificity of the BPAS + among Hispanics in terms of identifying children who warrant further medical evaluation for asthma. RESULTS: The sensitivity and specificity of the asthma portion of the Spanish BPAS+ were 74% and 86%, respectively. The sensitivity and specificity of the asthma portion of the English BPAS+ were 61% and 83%, respectively. CONCLUSIONS: The asthma portion of the BPAS+, a valid screen for identifying children who are in need of further evaluation for potentially undiagnosed asthma, is valid for low-income Hispanics in Spanish and English. As the Hispanic population continues to grow, it is imperative that researchers have English and Spanish instruments that are valid for this population.     

Information seeking behavior and perceived health literacy of family caregivers of persons living with a chronic condition. The case of spinal cord injury in Switzerland

ObjectiveTo examine the information seeking behavior and health literacy of caregivers of individuals living with spinal cord injury in Switzerland and their impact on the caregiving experience.MethodsNationwide survey of family caregivers of people with spinal cord injury (N = 717). Caregivers aged 18+ who assisted with activities of daily living were included. Self-reported information seeking behavior, including topics, preferred sources, and health literacy were assessed and analyzed.ResultsHealth professionals were the most trusted source of information. Among information-seekers, higher health literacy levels were shown to be associated with lower subjective caregiver burden and, in turn, with higher caregivers’ satisfaction with own health.ConclusionCaregivers use information on different topics and coming from different sources. In order for information to improve the caregiving experience, however, caregivers need health literacy skills to make sense of it.Practice implicationsBuilding health literacy is a promising approach to support caregivers in their activities, reduce their subjective burden, and even to improve their health. Interventions should consider involving health professionals, as the most trusted source of information, and address both health-related and more practical issues.     

Validation of health literacy domains for informed decision making about colorectal cancer screening using classical test theory and item response theory

ObjectiveTo construct and validate a computer-based and performance-based instrument to assess health literacy skills for informed decision making in colorectal cancer screening among screening invitees.MethodsAn instrument was constructed based on a conceptual framework of health literacy skills in colorectal cancer screening and findings from an expert survey. The instrument was field-tested among individuals with low health literacy (n = 28). Its validity and reliability was assessed using classical test theory and item response theory approaches in an online panel of colorectal cancer screening invitees (n = 696).ResultsConfirmatory factor analysis confirmed four separate factors: Comprehension, Application, Numeracy and Communication. A fifth domain (Appraisal) demonstrated poor reliability and validity and was omitted in further analyses. Internal consistency (Cronbach’s alpha > 0.6 for the four scales) was acceptable and test-retest reliability was moderate. The four factors were measurement invariant for age, sex and educational level.ConclusionThe computer-based measures were acceptable for self-administration. The constructed multidimensional health literacy instrument showed acceptable measurement properties.Practice implicationsOur findings imply that the computer-based instrument can be used for the development of interventions to support informed decision making about colorectal cancer screening among individuals with varying health literacy levels. Further research is needed for optimizing performance-based measurement of the Appraisal and Communication domains.     

Impact of language preference and health literacy on health information-seeking experiences among a low-income,multilingual cohort

ObjectiveWe examined the impact of language preference and health literacy on health information-seeking experiences in a multilingual, low-income cohort.MethodsWe administered a modified Health Information National Trends Survey in English, Spanish, and Chinese to a sample of San Francisco city/county residents. Using multivariable logistic regression analyses, we assessed how language and health literacy impact health information-seeking experiences (confidence, effort, frustration, quality concerns, and difficulty understanding information), adjusting for age, gender, race/ethnicity, education, usual place of care, health status, information-seeking behaviors, and smartphone ownership.ResultsOf 1000 participants (487 English-speaking, 256 Spanish-speaking, 257 Chinese-speaking), 820 (82%) reported at least one negative health information-seeking experience. Chinese-language was associated with frustration (aOR = 2.56; 1.12–5.86). Difficulty understanding information was more likely in Spanish-language respondents (aOR = 3.58; 1.25–10.24). Participants with limited health literacy reported more effort (aOR = 1.97; 1.22–3.17), frustration (aOR = 2.09; 1.28–3.43), concern about quality (aOR = 2.72; 1.60–4.61), and difficulty understanding information (aOR = 2.53; 1.58–4.05). Language and literacy impacted confidence only in the interaction term between Chinese-speakers and health literacy.ConclusionWe found that negative health information-seeking experiences were common in non-English speaking populations those with limited health literacy.Practice implicationsHealth communication efforts should consider both language preference and health literacy to ensure accessibility for all patients.     

Trusting Social Media as a Source of Health Information: Online Surveys Comparing the United States,Korea, and Hong Kong

BackgroundThe Internet has increasingly become a popular source of health information by connecting individuals with health content, experts, and support. More and more, individuals turn to social media and Internet sites to share health information and experiences. Although online health information seeking occurs worldwide, limited empirical studies exist examining cross-cultural differences in perceptions about user-generated, experience-based information compared to expertise-based information sources.ObjectiveTo investigate if cultural variations exist in patterns of online health information seeking, specifically in perceptions of online health information sources. It was hypothesized that Koreans and Hongkongers, compared to Americans, would be more likely to trust and use experience-based knowledge shared in social Internet sites, such as social media and online support groups. Conversely, Americans, compared to Koreans and Hongkongers, would value expertise-based knowledge prepared and approved by doctors or professional health providers more.MethodsSurvey questionnaires were developed in English first and then translated into Korean and Chinese. The back-translation method ensured the standardization of questions. Surveys were administered using a standardized recruitment strategy and data collection methods.ResultsA total of 826 participants living in metropolitan areas from the United States (n=301), Korea (n=179), and Hong Kong (n=337) participated in the study. We found significant cultural differences in information processing preferences for online health information. A planned contrast test revealed that Koreans and Hongkongers showed more trust in experience-based health information sources (blogs: t _451.50=11.21, P<.001; online support group: t _455.71=9.30, P<.001; social networking sites [SNS]: t _466.75=11.36, P<.001) and also reported using blogs (t _515.31=6.67, P<.001) and SNS (t _529.22=4.51, P<.001) more frequently than Americans. Americans showed a stronger preference for using expertise-based information sources (eg, WebMD and CDC) compared to Koreans and Hongkongers (t _360.02=3.01, P=.003). Trust in expertise-based information sources was universal, demonstrating no cultural differences (Brown-Forsythe F _2,654=1.82, P=.16). Culture also contributed significantly to differences in searching information on behalf of family members (t _480.38=5.99, P<.001) as well as to the goals of information searching.ConclusionsThis research found significant cultural differences in information processing preferences for online health information. Further discussion is included regarding effective communication strategies in providing quality health information.     

The Effect of Individual Factors on Health Behaviors Among College Students: The Mediating Effects of eHealth Literacy

BackgroundCollege students’ health behavior is a topic that deserves attention. Individual factors and eHealth literacy may affect an individual’s health behaviors. The integrative model of eHealth use (IMeHU) provides a parsimonious account of the connections among the digital divide, health care disparities, and the unequal distribution and use of communication technologies. However, few studies have explored the associations among individual factors, eHealth literacy, and health behaviors, and IMeHU has not been empirically investigated.ObjectiveThis study examines the associations among individual factors, eHealth literacy, and health behaviors using IMeHU.MethodsThe Health Behavior Scale is a 12-item instrument developed to measure college students’ eating, exercise, and sleep behaviors. The eHealth Literacy Scale is a 12-item instrument designed to measure college students’ functional, interactive, and critical eHealth literacy. A nationally representative sample of 525 valid college students in Taiwan was surveyed. A questionnaire was administered to collect background information about participants’ health status, degree of health concern, major, and the frequency with which they engaged in health-related discussions. This study used Amos 6.0 to conduct a confirmatory factor analysis to identify the best measurement models for the eHealth Literacy Scale and the Health Behavior Scale. We then conducted a multiple regression analysis to examine the associations among individual factors, eHealth literacy, and health behaviors. Additionally, causal steps approach was used to explore indirect (mediating) effects and Sobel tests were used to test the significance of the mediating effects.ResultsThe study found that perceptions of better health status (t₅₂₀=2.14-6.12, P<.001-.03) and greater concern for health (t₅₂₀=2.58-6.95, P<.001-.003) influenced college students’ development of 3 dimensions of eHealth literacy and adoption of healthy eating, exercise, and sleep behaviors. Moreover, eHealth literacy played an intermediary role in the association between individual factors and health behaviors (Sobel test=2.09-2.72, P<.001-.03). Specifically, higher levels of critical eHealth literacy promoted students’ health status and their practice of multiple positive health behaviors, including eating, exercise, and sleep behaviors.ConclusionsBecause this study showed that eHealth literacy mediates the association between individual factors and health behaviors, schools should aim to enhance students’ eHealth literacy and promote their health behaviors to help them achieve high levels of critical eHealth literacy. Although some of the study’s hypotheses were not supported in this study, the factors that influence health behaviors are complex and interdependent. Therefore, a follow-up study should be conducted to further explore how these factors influence one another.     

General and health-related social media use among adults with children in the household: Findings from a national survey in the United States

ObjectiveExamine predictors of social media use among a nationally representative sample of adults with children in the household.MethodsData were collected from the Health Information National Trends (HINTS) Survey from 2017 to 2020 (N = 3559). Multivariate logistic regression models assessed the association between sociodemographic variables and social networking site (SNS) use, SNS use to share health information, participation in online forum or support groups for health issues and watching health-related videos on YouTube.ResultsOlder adults and men were significantly less likely to use social media (p<.05). Non-Hispanic African American (aOR: 1.83; 95%CI: 1.30–2.57), Hispanic (aOR: 2.16; 95%CI: 1.56–2.99), and Asian (aOR: 2.82; 95%CI: 1.67–4.75) adults were more likely to watch health-related videos on YouTube.ConclusionsRacial/ethnic minorities with children in the household were more likely to seek health information on YouTube, highlighting opportunities to disseminate culturally relevant, accurate messages on the platform. Effective health communication targeted to specific demographics can help counter misinformation and promote health behavior particularly during public health emergencies.Practice ImplicationsProviders need to foster trust so that patients are comfortable to ask questions in addition to seeking information online. Providers can direct patients to credible resources to counter misinformation exposure and promote healthy behavior.     

eHealth literacy in chronic disease patients: An item response theory analysis of the eHealth literacy scale (eHEALS)

BackgroundChronic disease patients are affected by low computer and health literacy, which negatively affects their ability to benefit from access to online health information.ObjectiveTo estimate reliability and confirm model specifications for eHealth Literacy Scale (eHEALS) scores among chronic disease patients using Classical Test (CTT) and Item Response Theory techniques.MethodsA stratified sample of Black/African American (N = 341) and Caucasian (N = 343) adults with chronic disease completed an online survey including the eHEALS. Item discrimination was explored using bi-variate correlations and Cronbach’s alpha for internal consistency. A categorical confirmatory factor analysis tested a one-factor structure of eHEALS scores. Item characteristic curves, in-fit/outfit statistics, omega coefficient, and item reliability and separation estimates were computed.ResultsA 1-factor structure of eHEALS was confirmed by statistically significant standardized item loadings, acceptable model fit indices (CFI/TLI > 0.90), and 70% variance explained by the model. Item response categories increased with higher theta levels, and there was evidence of acceptable reliability (ω = 0.94; item reliability = 89; item separation = 8.54).ConclusioneHEALS scores are a valid and reliable measure of self-reported eHealth literacy among Internet-using chronic disease patients.Practice implicationsProviders can use eHEALS to help identify patients’ eHealth literacy skills.
