Utilization of the Newest Vital Sign (NVS) in Practice in the United States

Adaptation of a health literacy screener for computerized, self-administered use by U.S. adults

Objective

Health literacy is a critical health determinant, for which few computerized, self-administered assessments exist. This study adapted and tested the reliability of the Newest Vital Sign© (NVS) as a computerized, self-administered health literacy screener.

Methods

Phase one involved 33 participants to create response options for a computerized, self-administered NVS (C-NVS). Phase two was a randomized crossover trial to test the consistency of C-NVS and original, interviewer-administered NVS (I-NVS) scores in 89 participants.

Results

Linear mixed-effects regression model results showed a significant carryover effect (p < .001). Crossover trial data from time 1 showed that participants who initially received the C-NVS had significantly higher average scores (M = 5.7, SD = 0.6) than participants who received the I-NVS (M = 4.5, SD = 1.5; t(87) = 5.25, p < .001). Exploratory analysis results showed that when the washout period was longer than 33 days (75th percentile) the carryover effect was not statistically significant (p = .077).

Conclusion and innovation

Findings suggest learning can occur when health literacy screeners are administered more than once in less than a month's time and computerized, self-administered health literacy screeners may produce ceiling effects. A universal precautions approach to health literacy therefore remains germane.

Health literacy in older adults: The newest vital sign and its relation to cognition and healthy lifestyle behaviors

Health literacy tends to decrease with age, and lower health literacy has been associated with lower levels of physical function, mental health, and medication adherence. The present study examined health literacy in relation to cognition in a sample of community-dwelling older adults. The study also examined the impact of health literacy on engagement in healthy aging lifestyle behaviors. Participants included 128 older adults (age: M = 72.07, SD = 6.71; education: M = 16.34, SD = 2.56; 74% female) who completed a health literacy measure (Newest Vital Sign; NVS), a lifestyle behavior questionnaire (Healthy Aging Activity Engagement scale; HAAE), and several neuropsychological tests. The cognitive domains assessed included memory, executive function, and attention/working memory. Two variables were computed from the NVS to represent the health literacy factors of document and numeracy literacy; these factors demonstrated a small correlation (r = .18). Results revealed that attention/working memory, executive function, and memory were all significantly related to numeracy literacy and overall health literacy. Only memory was significantly related to document literacy. After accounting for age, education, and cognition, a hierarchical regression revealed that health literacy significantly predicted engagement in healthy aging lifestyle behaviors. Multiple cognitive abilities are necessary for searching, finding, and processing information to make health-related decisions. Health literacy accounted for a significant amount of variance in older adults' engagement in everyday lifestyle behaviors. Health literacy skills may be an area of focus for intervention efforts to improve brain health in older adults.

The Impact of Parental Electronic Health Literacy on Disease Management and Outcomes in Pediatric Type 1 Diabetes Mellitus: Cross-Sectional Clinical Study

BACKGROUND

Despite the growing uptake of smart technologies in pediatric type 1 diabetes mellitus (T1DM) care, little is known about caregiving parents' skills to deal with electronic health information sources.

OBJECTIVE

We aimed to assess the electronic health literacy of parents caring for children with T1DM and investigate its associations with disease management and children's outcomes.

METHODS

A cross-sectional survey was performed involving 150 parent-child (8-14 years old with T1DM) dyads in a university pediatric diabetology center. Parents' electronic health literacy (eHealth Literacy Scale [eHEALS]), general health literacy (Chew questionnaire and Newest Vital Sign [NVS]), and attitudes toward T1DM care (Parental Self-Efficacy Scale for Diabetes Management [PSESDM] and Hypoglycemia Fear Survey [HFS]) were investigated. Children's treatment, HbA1c level, and quality of life (Pediatric Quality of Life Inventory Diabetes Module [PedsQL Diab] and EQ-5D-Y-3L) were assessed. Multiple linear regression analysis was performed to investigate the determining factors of 6-month average HbA1c.

RESULTS

Of the 150 children, 38 (25.3%) used a pen, 55 (36.7%) used a pen plus a sensor, 6 (4.0%) used an insulin pump, and 51 (34.0%) used an insulin pump plus a sensor. Parents' average eHEALS score (mean 31.2, SD 4.9) differed significantly by educational level (P=.04) and the children's treatment (P=.005), being the highest in the pump + sensor subgroup. The eHEALS score showed significant Pearson correlations with the Chew score (r=-0.45; P<.001), NVS score (r=0.25; P=.002), and PSESDM score (r=0.35; P<.001) but not with the children's HbA1c (r=-0.143; P=.08), PedsQL Diab (r=-0.0002; P>.99), and EQ-5D-Y-3L outcomes (r=-0.13; P=.12). Regression analysis revealed significant associations of the child's HbA1c level with sex (β=0.58; P=.008), treatment modality (pen + sensor: β=-0.66; P=.03; pump + sensor: β=-0.93; P=.007), and parents' self-efficacy (PSESDM; β=-0.08; P=.001).

CONCLUSIONS

Significantly higher parental electronic health literacy was found in T1DM children using a glucose sensor. The electronic health literacy level was associated with parents' diabetes management attitude but not with the child's glycemic control. Studies further investigating the role of parental electronic health literacy in T1DM children managed at different levels of care and the local context are encouraged.

Assessing the health literacy of caregivers in the pediatric intensive care unit: a mixed-methods study

Background

Limited health literacy is associated with increased hospitalizations, emergency visits, health care costs, and mortality. The health literacy levels of caregivers of critically ill children are unknown. This mixed-methods study aims to quantitatively assess the health literacy of caregivers of children admitted to the pediatric intensive care unit (PICU) and qualitatively describe facilitators and barriers to implementing health literacy screening from the provider perspective.

Methods

Caregivers of patients admitted to our large, academic PICU (between August 12, 2022 and March 31, 2023) were approached to complete a survey with the Newest Vital Sign (NVS), which is a validated health literacy screener offered in English and Spanish. We additionally conducted focus groups of interdisciplinary PICU providers to identify factors which may influence implementation of health literacy screening using the Consolidated Framework for Implementation Research (CFIR) framework.

Results

Among 48 surveyed caregivers, 79% demonstrated adequate health literacy using the Newest Vital Sign screener. The majority of caregivers spoke English (96%), were mothers (85%), and identified as White (75%). 83% of caregivers were able to attend rounds at least once and 98% believed attending rounds was helpful. Within the PICU provider focus groups, there were 11 participants (3 attendings, 3 fellows, 2 nurse practitioners, 1 hospitalist, 2 research assistants). Focus group participants described facilitators and barriers to implementation, which were mapped to CFIR domains. Timing of screening and person administering screening were identified as modifiable factors to improve future implementation.

Conclusion

We found the health literacy levels of PICU caregivers in our setting is similar to prior assessments of parental health literacy. Participation in morning rounds was helpful for developing understanding of their child's illness, regardless of health literacy status. Qualitative feedback from providers identified barriers across all CFIR domains, with timing of screening and person administering screening as modifiable factors to improve future implementation.

Social Determinants of Health and Informed Consent Comprehension for Pediatric Cancer Clinical Trials

Importance

Ensuring valid informed consent (IC) prior to enrollment in clinical trials is a fundamental ethical right.

Objective

To assess whether social determinants of health (SDOH) and related sociocontextual factors are associated with parental IC comprehension in therapeutic childhood cancer clinical trials.

Design, Setting, and Participants

This cross-sectional study prospectively enrolled 223 parents of children with newly diagnosed cancer at Rady Children's Hospital San Diego, a large quaternary academic center in California, from October 1, 2014, to March 31, 2021. Linear mixed effects models were used to assess whether IC comprehension overall and by domain (purpose, procedures, and randomization; risks and benefits; alternatives; and voluntariness) were associated with SDOH and sociocontextual factors. Data were analyzed from January 1, 2022, to July 31, 2023.

Exposures

Informed consent for a therapeutic childhood cancer clinical trial.

Main Outcomes and Measures

The primary outcome of interest was IC comprehension and its associations with SDOH (marital status, language, educational attainment, employment, insurance type, socioeconomic status, and health literacy) and sociocontextual factors (ethnicity, satisfaction with informed consent, and cancer type).

Results

Of 223 parents, 172 (77.1%) were aged 18 to 44 years, 111 (49.8%) were Hispanic, 152 (68.2%) were women, and 163 (73.1%) were married. In terms of race, 2 (0.9%) were American Indian or Alaska Native, 22 (9.9%) were Asian or Pacific Islander, 8 (3.6%) were Black, 149 (66.8%) were White, and 42 (18.8%) were more than 1 race. In multivariable linear mixed-effects analyses, limited vs adequate health literacy was associated with lower comprehension of informed consent overall (mean [SD], 68.28 [11.81] vs 79.24 [11.77]; β estimate, -9.02 [95% CI, -12.0 to -6.07]; P < .001) and with lower comprehension of the purpose, procedures, and randomization (mean [SD], 65.00 [12.64] vs 76.14 [11.53]; β estimate, -7.87 [95% CI, -10.9 to -4.85]; P < .001); risks and benefits (mean [SD], 62.84 [20.24] vs 73.14 [20.86]; β estimate, -10.1 [95% CI, -15.6 to -4.59]; P < .001); alternatives (mean [SD], 54.27 [43.18] vs 82.98 [34.24]; β estimate, -14.3 [95% CI, -26.1 to -2.62]; P  .02); and voluntariness (mean [SD], 76.52 [24.33] vs 95.39 [13.89]; β estimate, -9.14 [95% CI, -14.9 to -3.44]; P = .002) domains. Use of Spanish vs English language for medical communication was associated with lower comprehension overall (mean [SD], 66.45 [12.32] vs 77.25 [12.18]; β estimate, -5.30 [95% CI, -9.27 to -1.34]; P = .01) and with lower comprehension of the purpose, procedures, and randomization (mean [SD], 63.33 [11.98] vs 74.07 [12.52]; β estimate, -4.33 [95% CI, -8.43 to -0.23]; P = .04) and voluntariness (mean [SD], 70.83 [24.02] vs 92.54 [17.27]; β estimate, -9.69 [95% CI, -16.8 to -2.56]; P = .009) domains.

Conclusions and Relevance

In this cross-sectional study including parents of children with newly diagnosed cancer who provided IC for their child's participation in a therapeutic clinical trial, limited health literacy and use of Spanish language for medical communication were associated with lower comprehension of IC. These findings suggest that, in this setting, parents with limited health literacy or those who use Spanish language for medical communication may not fully comprehend IC and therefore may not make truly informed decisions. These findings support the investigation of interventions, across pediatric disciplines, tailored to the participant's language and health literacy level to improve IC comprehension, particularly in racial and ethnic minority populations.

Preference Elicitation and Treatment Decision-Making Among Men Diagnosed With Prostate Cancer: Randomized Controlled Trial Results of Healium

BACKGROUND

Elicitation of patients' preferences is an integral part of shared decision-making, the recommended approach for prostate cancer decision-making. Existing decision aids for this population often do not specifically focus on patients' preferences. Healium is a brief interactive web-based decision aid that aims to elicit patients' treatment preferences and is designed for a low health literate population.

OBJECTIVE

This study used a randomized controlled trial to evaluate whether Healium, designed to target preference elicitation, is as efficacious as Healing Choices, a comprehensive education and decision tool, in improving outcomes for decision-making and emotional quality of life.

METHODS

Patients diagnosed with localized prostate cancer who had not yet made a treatment decision were randomly assigned to the brief Healium intervention or Healing Choices, a decision aid previously developed by our group that serves as a virtual information center on prostate cancer diagnosis and treatment. Assessments were completed at baseline, 6 weeks, and 3 months post baseline, and included decisional outcomes (decisional conflict, satisfaction with decision, and preparation for decision-making), and emotional quality of life (anxiety/tension and depression), along with demographics, comorbidities, and health literacy.

RESULTS

A total of 327 individuals consented to participate in the study (171 were randomized to the Healium intervention arm and 156 were randomized to Healing Choices). The majority of the sample was non-Hispanic (272/282, 96%), White (239/314, 76%), married (251/320, 78.4%), and was on average 62.4 (SD 6.9) years old. Within both arms, there was a significant decrease in decisional conflict from baseline to 6 weeks postbaseline (Healium, P≤.001; Healing Choices, P≤.001), and a significant increase in satisfaction with one's decision from 6 weeks to 3 months (Healium, P=.04; Healing Choices, P=.01). Within both arms, anxiety/tension (Healium, P=.23; Healing Choices, P=.27) and depression (Healium, P=.001; Healing Choices, P≤.001) decreased from baseline to 6 weeks, but only in the case of depression was the decrease statistically significant.

CONCLUSIONS

Healium, our brief decision aid focusing on treatment preference elicitation, is as successful in reducing decisional conflict as our previously tested comprehensive decision aid, Healing Choices, and has the added benefit of brevity, making it the ideal tool for integration into the physician consultation and electronic medical record.

Health literacy in female patients affected by anorexia nervosa and bulimia nervosa: a cross-sectional study with pair-matched controls

PURPOSE

Health Literacy (HL) consists in all the skills and knowledges used by people to understand and seek health-related information. Inadequate levels of HL substantially affect many different aspects of health. The primary aim of the present study was to assess levels of HL in female patients with anorexia nervosa (AN) and bulimia nervosa (BN), compared with matched control subjects.

METHODS

A consecutive series of 64 female patients with AN and BN (mean age 23.1 ± 7.0) was enrolled, matched with 64 female control subjects (mean age 23.7 ± 7.1). Both groups completed the Health Literacy Survey Questionnaire (HLS-EU-Q16) and the Newest Vital Sign (NVS), which evaluate subjective and objective HL level respectively.

RESULTS

Patients with AN and BN showed lower levels of subjective HL (10.0 ± 3.5 vs. 11.3 ± 3.0) and higher levels of objective HL (5.0 ± 1.3 vs. 3.6 ± 1.6) when compared with controls. No difference between AN and BN was found. No correlation between HLS-EU-Q16 Total Score and duration of illness was found. A negative correlation was found between EDE-Q Eating Concerns and subjective HL levels. HLS-EU-Q16 Total Score was predicted by educational level in control subjects only, while NVS Total Score was not predicted by educational level in control subjects nor in patients.

CONCLUSION

Patients with AN and BN had lower levels of subjective HL. NVS scores could overestimate objective HL in female patients with AN and BN. The promotion of HL in areas differing from those that concern nutritional characteristics of food, could be a therapeutic target for these patients.

Access to Healthcare and Health Literacy in Croatia: Empirical Investigation

Health literacy is related to different health-related outcomes. However, the nature of the relationship between health literacy and health outcomes is not well understood. One pathway may lead from health literacy to health outcomes by means of access to healthcare. The goal of the current study is to explore the association between health literacy and the particular measure of access to healthcare-unmet medical need-for the first time in Croatia and, to the best of our knowledge, for the first time in the EU context. We use data obtained from face-to-face interviews in a large nationally representative sample of the Croatian population (n = 1000) to estimate the level of health literacy and self-reported access to care and investigate the association between health literacy and self-perceived barriers to access. Our study showed that limited and problematic health literacy is prevalent and associated with higher rates of unmet medical need. Unmet need is largely caused by long waiting lists. It is therefore essential to design health services fitting the needs of those who have limited and/or problematic health literacy as well as enhance health education with the potential of improving the access to care and health outcomes as well as design policies that reduce waiting times.

Development and assessment of a low literacy, pictographic asthma action plan with clinical automation to enhance guideline-concordant care for children with asthma

OBJECTIVE

Asthma is characterized by reversible pulmonary symptoms, frequent hospitalizations, poor quality of life, and varied treatment. Parents with low health literacy (HL) is linked to poor asthma outcomes in children. Recent practice updates recommended inhaled corticosteroids for the management of persistent asthma, but guideline-concordant care is suboptimal. Our aim was to develop and assess an Asthma Action Plan (AAP) that could serve as an individualized plan for low HL families and facilitate guideline-concordant care for clinicians.

METHODS

We followed the National Institute of Health 5-step "Clear & Simple" approach to develop the Uniformed Services AAP. Our AAP included symptom pictographs (dyspnea, cough, sleep, activity) and guideline-concordant clinical automation tools. Caregivers assessed the pictograms for validity (transparency of ≥ 85%; translucency score ≥ 5; and ≥ 85% recall). Readability was assessed using 7 formulas. (<6th Grade was acceptable). Comprehensibility, design quality, and usefulness was assessed by caregivers using the Consumer Information Rating Form (CIRF) (>80% was acceptable). Understandability and actionability was assessed by medical librarians using the Patient Education Materials Assessment Tool-Printable (>80% was acceptable). Suitability was assessed by clinicians using the modified Suitability Assessment of Materials (SAM) instrument (>70% was superior).

RESULTS

All 12 pictograms were validated (N = 118 respondents). Readability demonstrated a 4th grade level. Overall CIRF percentile score = 80.4%. Understandability and Actionability = 100%. Suitability score = 75%.

CONCLUSIONS

Our AAP was formally endorsed by the Allergy & Asthma Network. The Uniformed Services AAP is a novel tool with embedded clinical automation that can address low HL and enhance guideline-concordant care.

The Uniformed Services Constipation Action Plan: An Effective Tool for the Management of Children with Functional Constipation

OBJECTIVE

To implement and to evaluate the effectiveness of the Uniformed Services Constipation Action Plan (USCAP) in our gastroenterology clinic for children with functional constipation.

STUDY DESIGN

This implementation science study included toilet-trained subjects aged 4 years and older who met the Rome IV criteria for functional constipation. Children were block randomized to receive either the USCAP or control. All clinic functional constipation plans recommended subjects continue pharmacotherapy for 4 months. Endpoints measured were clinical outcomes (resolution of functional constipation and achievement of a Pediatric Bristol Stool Form Scale [PBSFS] score of 3 or 4), patient-related outcomes (health-related quality of life [HRQoL] total scale score), and health confidence outcomes (Health Confidence Score [HCS]).

RESULTS

Fifty-seven treatment group subjects (44%) received a USCAP (52% male; mean age, 10.9 [4.9] years) compared with 73 controls (56%; 48% male; mean age,10.9 [5.3] years). A PBSFS score of 3 or 4 was achieved by 77% of the treatment group compared with 59% of controls (P = .03). Subjects from the treatment group were more likely than the controls to endorse adherence to the 4-month course of pharmacotherapy (P < .001). Subjects who received a USCAP had greater improvements in HRQoL total scale score by the end of the project (P = .04).

CONCLUSIONS

The USCAP is a simple, inexpensive tool that has the potential to improve global outcomes for functional constipation in children and should be recommended as standard clinical practice.

Moderators and Mediators of the Relationship of Shared Decision-Making and Satisfaction

Background:Evidence suggests that health literacy, perceived availability of information and guidance to adapt to challenges (informational support), and symptoms of depression all have the potential to mediate or moderate the relationship between patient-rated involvement in decisions and satisfaction with care. If so these could be useful targets for improving patient experience. Methods: We prospectively enrolled 130 new adult patients visiting an orthopedic surgeon over a 4-month period. All patients were asked to complete measures of satisfaction with care (21-item Medical Interview Satisfaction Scale), perceived involvement in decisions (9-item Shared Decision-Making Questionnaire), symptoms of depression (the Patient-Reported Outcomes Measurement Information Scale [PROMIS] Depression Computerized Adaptive Test [CAT]), perceived availability of information and guidance to adapt to challenges (PROMIS Informational Support CAT), and the Newest Vital Sign test of health literacy. Results: The strong correlation between satisfaction with care (ρ = 0.60, P < .001) and perceived involvement in decisions was neither mediated nor moderated by health literacy, perceived availability of information and guidance, and symptoms of depression. Conclusions: The observation that patient-rated shared decision-making is strongly related to satisfaction with an office visit, independent of health literacy, perceived support, and symptoms of depression, is consistent with evidence that various measures of patient experience tend to correlate and emphasizes the importance of the patient-clinician relationship. Level of Evidence: Level II, prospective study.

Perceived Physician Empathy in Pediatric Orthopedics: A Cross-Sectional Study

Empathy is the cornerstone of the patient–physician relationship and is consistently ranked by patients as one of the most important factors in the quality of their care. In this paper we examine the degree to which perceived physician empathy is associated with the characteristics of the caregiver (parent or legal guardian) and physician in pediatric orthopedic surgery. This was a cross-sectional survey study of 200 English-speaking caregivers of pediatric patients at a large children's hospital. The Consultation and Relational Empathy (CARE) Measure was used to measure perceived physician empathy. Only if the caregiver felt carefully listened to by the physician (p-value < 0.001), and if the physician showed respect for what the caregiver had to say (p-value = 0.007) were statistically significant and positively associated with perceived physician empathy. The most significant determinant of perceived physician empathy is whether the caregiver felt listened to during the encounter. Other factors such as caregiver demographics, health literacy, self-rated mental health, wait time, and time spent with the physician do not significantly affect perceived physician empathy.

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

OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

PRACTICE IMPLICATIONS

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

Electronic health literacy and health-related outcomes among older adults: A systematic review

This review aims to identify, appraise, and synthesize research evidence of the association between electronic health (eHealth) literacy and health outcomes in older adults. English-written articles that presented the relationships between eHealth literacy and health-related outcomes in older adults were identified by searching five scientific databases (Web of Science, PubMed, Cochrane Library, APA PsycInfo, and EMBASE) hand-searching reference lists. Searches yielded 2993 studies after duplicates were removed, of which 24 publications were included in the final review. eHealth literacy was relatively low in older adults, and the eHealth Literacy Scale, developed by Norman and Skinner in 2006, was the most frequently used instrument in the included studies (21/24, 87.5%). The health-related outcomes associated with eHealth literacy were grouped into four categories: physical, behavioral, psychosocial, and cognitive. For behavioral (e.g., health-promoting behaviors, self-care, and medication adherence) and cognitive (e.g., health knowledge and health decision making) outcomes, the evidence was mostly consistent that eHealth literacy was positively associated with better outcomes. For physical (e.g., health-related quality of life) and psychosocial outcomes (e.g., anxiety and self-efficacy), the associations were less consistent, with some studies showing significant associations while others showed no associations. Most included studies were assessed as moderate quality. Overall, higher eHealth literacy is associated with more positive health behaviors and better health knowledge and attitude in older adults, however, the associations with some physical and psychosocial outcomes are less consistent. Clarifying the pathways of the relationships between eHealth literacy and some health-related outcomes is needed for further exploring their underlying mechanisms.

Pilot testing of nurse led multimodal intervention for falls prevention

Patient fall-risk awareness, self-efficacy, and engagement in fall-prevention activities are important aspects of fall-prevention. The current pilot study examined the effect of a nurse-led multimodal intervention on hospitalized adults' levels of fall risk awareness, self-efficacy, and engagement in fall prevention. Sixty hospitalized older adults in an acute care setting in Florida participated in the study. There were significant differences [pre-test (M = 19.02, SD=1.152) and post-test (M = 21.71, SD=0.527); t (17.355) = 58, p≤.001] on level of fall risk awareness in fall prevention. There were no significant findings for fall self-efficacy and engagement. Study findings suggested that the higher the fall self-efficacy, the higher the engagement. Future research is needed to examine self-efficacy and engagement for fall prevention in larger diverse cohorts of hospitalized older adults.

Health Literacy, Education, and Internal Consistency of Psychological Scales

Background:

Measurement error might lead to biased estimates, causing ineffective interventions and service delivery. Identifying measurement error of health-related instruments helps develop accurate assessment of health-related constructs.

Objective:

We compared the internal consistency of eight psychological scales used in health research in groups with adequate versus limited health literacy and in groups with higher versus lower education.

Methods:

Participants (N = 1,005) from a nationally representative internet panel completed eight self-report scales: (1) information avoidance, (2) cognitive causation, (3) unpredictability, (4) perceived severity, (5) time orientation, (6) internal health locus of control, (7) need for cognition, and (8) social desirability. The first four assess beliefs about diabetes and colon cancer. We used the Newest Vital Sign to categorize participants' health literacy (limited vs. adequate). We also categorized participants' education (high school or less vs. more than high school). We compared the Cronbach's alpha for each psychological scale between groups with different health literacy and education levels using the Feldt test.

Key Results:

Among all the 13 subscales, scale internal consistency was significantly lower among people with limited health literacy than those with adequate health literacy for five subscales: information avoidance for colon cancer (0.80 vs. 0.88), unpredictability of diabetes (0.84 vs. 0.88), perceived severity for diabetes (0.66 vs. 0.75), need for cognition (0.63 vs. 0.82), and social desirability (0.52 vs. 0.68). Internal consistency was significantly lower among people who had a high school education or less than among those with more than a high school education for four scales: perceived severity of diabetes (0.70 vs. 0.75), present orientation (0.60 vs. 0.66), need for cognition (0.73 vs. 0.80), and social desirability (0.61 vs. 0.70).

Conclusions:

Several psychological instruments demonstrated significantly lower internal consistency when used in a sample with limited health literacy or education. To advance health disparities research, we need to develop new scales with alternative conceptualizations of the constructs to produce a measure that is reliable among multiple populations. [HLRP: Health Literacy Research and Practice. 2021;5(3):e244–e255.]

Plain Language Summary:

We compared the internal consistency of several psychological scales in groups with adequate versus limited health literacy and higher versus lower education. For several scales, internal consistency was significantly lower among (1) people with limited health literacy compared those who have adequate health literacy and/or (2) people who had a high school education or less compared to those with more than a high school education.

What factors are associated with perceived disease onset in patients with hip and knee osteoarthritis?

Introduction

Newly symptomatic osteoarthritis (OA) is often misinterpreted as new pathology or injury, which is associated with pain intensity and incapability.

Methods

Adult patients with hip and knee OA completed measures of catastrophic thinking, depression, capability, symptom duration, and perceived injury.

Results

Symptom duration was associated with OA grade and symptoms of depression. Perceived injury was common (31%) and associated with men and knee arthritis. Capability was associated with misinterpretation of symptoms and the work status 'other,' but not radiographic severity.

Conclusions

Misinterpretation of OA symptoms is common and has a greater influence on capability than radiographic grade of pathophysiology.

Determinants of caregiver satisfaction in pediatric orthopedics

This study investigates determinants of pediatric orthopedic surgery patients' parent or guardian (caregiver) satisfaction with the physician in an outpatient office setting. This was a cross-sectional survey study of 200 English-speaking caregivers of pediatric patients that checked into the pediatric orthopedic clinic at the authors' institution from 1 March 2017 to 1 November 2018. Questionnaires given in clinic include the Newest Vital Sign and The Literacy in Musculoskeletal Problems survey to measure general and musculoskeletal health literacy, respectively, demographic information, expected/estimated wait time, Consultation and Relational Empathy Measure, and Consumer Assessment of Healthcare Providers and Systems Clinician and Group. After multivariate regression, only perceived physician empathy as measured by the Consultation and Relational Empathy Measure score was significantly correlated with caregiver satisfaction (P < 0.0001), accounting for 56% of the variability of caregiver satisfaction scores. The odds of a satisfaction score of at least 9 out of 10 were 21% higher for every unit increase of the Consultation and Relational Empathy Measure score [odds ratio = 1.21 (P < 0.0001)]. After logistic regression, the caregiver's gender was also correlated with patient satisfaction and the odds of a patient satisfaction score ≥9 for males was less than 1/4th that of females [odds ratio = 0.16 (P = 0.040)]. The most important determinant of caregiver satisfaction with the physician in an outpatient pediatric orthopedic setting is perceived physician empathy. This accounts for the majority of the caregiver's satisfaction. This is the first study to determine this relationship in pediatric orthopedic surgery.

Assessment of Factors Associated With Parental Perceptions of Voluntary Decisions About Child Participation in Leukemia Clinical Trials

IMPORTANCE

Obtaining voluntary informed consent prior to enrollment in clinical trials is a fundamental ethical requirement.

OBJECTIVE

To assess whether health literacy, contextual factors, or sociodemographic characteristics are associated with perception of voluntariness among parents who had consented for their child's participation in a leukemia therapeutic clinical trial.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study prospectively enrolled 97 parents of children diagnosed as having leukemia at Rady Children's Hospital San Diego, a large tertiary academic center in California, from 2014 to 2017. Health literacy, contextual factors (acculturation, decisional regret, and satisfaction with informed consent), sociodemographic characteristics, and perception of voluntariness after consenting for a therapeutic clinical trial were measured. Univariable and multivariable regression were used to determine significant associations. The analyses for the present study were conducted from May 2019 to May 2020.

EXPOSURES

Informed consent for a therapeutic leukemia clinical trial.

MAIN OUTCOMES AND MEASURES

The primary outcome of interest was perception of voluntariness and its associations with health literacy and other contextual factors (acculturation, decisional regret, and satisfaction with informed consent) and sociodemographic characteristics, including age, race/ethnicity, parental language, educational level, insurance type, marital status, and socioeconomic status.

RESULTS

Of 97 parents included, the majority were women (65 [67%]), married (71 [73%]), and of self-reported Hispanic ethnicity (50 [52%]). Lower perception of voluntariness was significantly associated with lower health literacy (r = 0.30; 95% CI, 0.11-0.47; P = .004), Spanish language (x̅ = -4.50, P = .05), lower acculturation if of Hispanic ethnicity (r = 0.30; 95% CI, 0.02-0.54; P = .05), greater decisional regret (r = -0.54; 95% CI, -0.67 to -0.38; P < .001), and lower satisfaction with informed consent (r = 0.39; 95% CI, 0.21-0.54; P < .001) in univariable analysis. Lower health literacy remained significantly associated with lower perception of voluntariness in multivariable analysis after adjustment for contextual factors and sociodemographic characteristics (β = 4.06; 95% CI, 1.60-6.53; P = .001). Lower health literacy was significantly associated with Hispanic ethnicity (mean, 4.16; 95% CI, 3.75-4.57; P < .001), Spanish language spoken at home (mean, 3.17; 95% CI, 1.94-4.40; P < .001), high school or less educational level (mean, 3.41; 95% CI, 2.83-3.99; P < .001), public insurance (mean, 4.00; 95% CI, 3.55-4.45; P < .001), and unmarried status (mean, 3.71; 95% CI, 2.91-4.51; P = .03).

CONCLUSIONS AND RELEVANCE

Among parents of children with newly diagnosed leukemia who had consented for their child's participation in a therapeutic clinical trial, lower perception of voluntariness was significantly associated with lower health literacy. These results suggest that parents with low health literacy may perceive external influences in their decision for their child's participation in clinical trials. This finding highlights the potential role of recruitment interventions tailored to the participant's health literacy level to improve voluntary informed consent in underserved populations.

Development and Assessment of a Pictographic Pediatric Constipation Action Plan

OBJECTIVE

To assess the Uniformed Services Constipation Action Plan (USCAP) as an evidence-based, personalized, clinical action tool with pictograms to aid clinicians and families in the management of functional constipation.

STUDY DESIGN

The USCAP facilitates the management functional constipation by using a health literacy-informed approach to provide instructions for pharmacotherapies and lifestyle modifications. This study included part 1 (pictogram validation) and part 2 (assessment). For part 1, pictogram transparency, translucency, and recall were assessed by parent survey (transparency ≥85%, mean translucency score ≥5, recall ≥85% required for validation). For part 2, the USCAP was assessed by parents, clinical librarians, and clinicians. Parental perceptions (n = 65) were assessed using the Consumer Information Rating Form (17 questions) to gauge comprehensibility, design quality and usefulness. Readability was assessed by 5 formulas and a Readability Composite Score was calculated. Clinical librarians (n = 3) used the Patient Education Materials Assessment Tool to measure understandability (19 questions) and actionability (7 questions) (>80% rating was acceptable). Suitability was assessed by clinicians (n = 34) using Doak's Suitability Assessment of Materials (superior ≥70% rating).

RESULTS

All 12 pictograms demonstrated appropriate transparency, translucency, and recall. Parental perceptions reflected appropriate comprehensibility, design quality, and usefulness. The Readability Composite Score was consistent with a fifth-grade level. Clinical librarians reported acceptable understandability and actionability. Clinicians reported superior suitability.

CONCLUSIONS

The USCAP met all criteria for clinical implementation and future study of USCAP implementation for treating children with chronic functional constipation.

Low Health Literacy Exists in the Inflammatory Bowel Disease (IBD) Population and Is Disproportionately Prevalent in Older African Americans

BACKGROUND

Low health literacy is common in general populations, but its prevalence in the inflammatory bowel disease (IBD) population is unclear. The objective of this study was to assess the prevalence of low health literacy in a diverse IBD population and to identify risk factors for low health literacy.

METHODS

Adult patients with IBD at a single institution from November 2017 to May 2018 were assessed for health literacy using the Newest Vital Sign (NVS). Demographic and socioeconomic data were also collected. Primary outcome was the prevalence of low health literacy. Secondary outcomes were length-of-stay (LOS) and 30-day readmissions after surgical encounters. Bivariate comparisons and multivariable regression were used for analyses.

RESULTS

Of 175 IBD patients, 59% were women, 23% were African Americans, 91% had Crohn disease, and mean age was 46 years (SD = 16.7). The overall prevalence of low health literacy was 24%. Compared to white IBD patients, African Americans had significantly higher prevalence of low health literacy (47.5% vs 17.0%, P < 0.05). On multivariable analysis, low health literacy was associated with older age and African American race (P < 0.05). Of 83 IBD patients undergoing abdominal surgery, mean postoperative LOS was 5.5 days and readmission rate was 28.9%. There was no significant difference between LOS and readmissions rates by health literacy levels.

CONCLUSIONS

Low health literacy is present in IBD populations and more common among older African Americans. Opportunities exist for providing more health literacy-sensitive care in IBD to address disparities and to benefit those with low health literacy.

Patient factors associated with diabetes medication adherence at different health literacy levels: a cross-sectional study at a family medicine clinic

BACKGROUND

Type 2 diabetes (T2D) incurs tremendous health costs associated with various complications due to poor diabetes control. Medication adherence, which is correlated with patients' health literacy, should be consistently practiced achieving optimal diabetes control. A deeper understanding of the specific communication and psychosocial factors related to medication-taking behaviors across different levels of health literacy among people with T2D will guide the development of effective interventions and strategies to enhance medication adherence.

OBJECTIVES

This cross-sectional study aimed to identify salient patient factors associated with diabetes medication adherence across different levels of health literacy.

METHODS

A questionnaire was administered via a face-to-face approach with 205 participants at a family medicine clinic. Study participants were all above 20 years of age with T2D, were prescribed at least one oral diabetes medication, and understood English. The questionnaire assessed participants' health literacy, self-efficacy for medication use, beliefs in medicines, patient-provider communication, perceived barriers to medication adherence, and self-reported medication adherence. Separate analysis of covariance was used to compare the mean scores of patient factors related to medication adherence across people with different health literacy levels.

RESULTS

The mean age of participants was 61 years old, and the majority of the participants were female (57%), White (75%), and college educated (62%). Thirty-three percent of the participants had adequate health literacy, but only 43% of them reported high adherence to their diabetes medications. Analysis of covariance showed that having stronger self-efficacy (P < 0.001), lower concern beliefs about medication (P = 0.047), and fewer perceived barriers to medication-taking (P < 0.001), are necessary for better medication adherence.

CONCLUSION

Findings suggest that practitioners should address concern beliefs among low-adherent patients with low health literacy, help improve self-efficacy, and address perceived barriers to medication adherence among all low-adherent patients to optimally support patients' diabetes care.

Cultural Worldviews and Perceived Risk of Colon Cancer and Diabetes

Individuals with different cultural worldviews conceptualize risks in distinct ways, yet this work has not extended to personal illness risk perception. The purpose of this study was to 1) examine the relationships between two types of cultural worldviews (Hierarchy-Egalitarian; Individualism-Communitarianism) and perceived risk (perceived severity and susceptibility) for diabetes and colon cancer, 2) test whether health literacy modifies the above relationships, and 3) investigate whether trust in government health information functions as a putative mediator of the relations between cultural worldviews and disease perceived risk. We recruited (N=600) participants from a nationally-representative Internet survey panel. Results were weighted so the findings are representative of the general United States population. People with a more hierarchical worldview expressed lower perceived susceptibility to developing both diabetes and colon cancer, and perceived these diseases to be less severe, relative to those with a less hierarchical (more egalitarian) worldview. There was no significant association between individualistic worldview and perceived risk. Health literacy modified the relationships between hierarchical worldview and perceived risk; the associations between hierarchical worldview and lower perceived severity were stronger for those with limited health literacy. We did not observe indirect effects of cultural worldviews on perceived risk through trust in health information from government sources. It may be useful to identify specifically tailored risk communication strategies for people with hierarchical and individualistic worldviews, especially those with limited health literacy, that emphasize their important cultural values. Further research examining cultural components of illness risk perceptions may enhance our understanding of risk-protective behaviors.

Health Literacy and Perceptions of Stigma

Calls for progress in health literacy argue that efforts across society are promising for increasing capacities at a broader level. However, it is unknown how the general public perceives people who struggle with health information. While it may be ideal to establish interventions beyond the individual, stigma held by others could limit this work. This study explores whether one's personal health literacy skills are associated with stigma enacted toward others who struggle with health literacy. Adults (N = 5,151) responded to a survey consisting of health literacy assessments and a vignette in which a patient made a health-related mistake. Differences were observed regarding the number of participants who self-reported (n = 251) versus objectively scored as having low health literacy (n = 794). Participants who self-reported (M_lowHL = 5.67, M_highHL = 5.99, p < .01) or had low objective health literacy (M_lowHL = 5.75, M_highHL = 6.01, p < .001) exhibited less pity for the person in the vignette than health literate participants. Participants were more demanding of a young person featured in the vignette (33-year old), indicating greater personal responsibility (M₇₂ = 5.12, M₃₃ = 5.67), anger (M₇₂ = 4.54, M₃₃ = 5.57), and less pity (M₇₂ = 6.18, M₃₃ = 5.75) compared to an older person (72-year old). Results from the present study suggest contradictory perceptions among patients who are likely to feel stigma themselves.

Health Literacy in Relation to Health Outcomes: A Concept Analysis

Health literacy is a concept discussed in the literature of many disciplines, but the definitions used are varied. Using the Walker and Avant method of concept analysis, the authors explore health literacy in relation to health outcomes-the defining attributes, antecedents, consequences, and empirical referents. In addition, cases are provided that illustrate health literacy in relation to health outcomes. This concept analysis allows for colleagues in nursing to have a better understanding of this concept and facilitates further development of tools to assess and improve health literacy and ultimately improve health outcomes overall.

The impact of caregiver health literacy on healthcare outcomes for low income minority children with asthma

Objectives: The aim of this exploratory study was to assess the impact of caregiver health literacy (HL) on health care outcomes for their child with asthma.Methods: Caregiver dyads across two different healthcare delivery systems completed a battery of validated asthma outcome instruments, including the Newest Vital Sign™ as a measure of HL for the caregivers of children ages 7-18 y. Utilization history was obtained through the electronic medical record. Descriptive analysis with bivariate associations was conducted.Results: There was no direct relationship between HL and asthma outcomes in the 34 Hispanic and African American caregiver-child dyads. However, caregiver health literacy was significantly related to language (p = 0.02). African American English-speaking caregivers, seen in an urban emergency department, demonstrated adequate health literacy. Hispanic Spanish-speaking caregivers, seeking care in a mobile asthma van, showed limited health literacy. There was no significant association between caregivers' HL and routine asthma care visits when language and child age were controlled.Conclusions: Assessing patient factors can identify persons at risk who need additional support to negotiate the healthcare system when providing care for a child with asthma.

Low Health Literacy and Health Information Avoidance but Not Satisficing Help Explain "Don't Know" Responses to Questions Assessing Perceived Risk

BACKGROUND

People who say they don't know (DK) their disease risk are less likely to engage in protective behavior.

PURPOSE

This study examined possible mechanisms underlying not knowing one's risk for common diseases.

METHODS

Participants were a nationally representative sample of 1005 members of a standing probability-based survey panel who answered questions about their comparative and absolute perceived risk for diabetes and colon cancer, health literacy, risk factor knowledge and health information avoidance, and beliefs about illness unpredictability. Survey satisficing was a composite assessment of not following survey instructions, nondifferentiation of responses, haphazard responding, and speeding. The primary outcomes were whether a person selected DK when asked absolute and comparative risk perception questions about diabetes or colon cancer. Base structural equation modeling path models with pathways from information avoidance and health literacy/knowledge to DK responding for each DK outcome were compared to models that also included pathways from satisficing or unpredictability beliefs.

RESULTS

Base models contained significant indirect effects of health literacy (odds ratios [ORs] = 0.94 to 0.97, all P < 0.02) and avoidance (ORs = 1.05 to 1.15, all P < 0.01) on DK responding through risk factor knowledge and a direct effect of avoidance (ORs = 1.21 to 1.28, all P < 0.02). Adding the direct effect for satisficing to models resulted in poor fit (for all outcomes, residual mean square error estimates >0.17, all weighted root mean square residuals >3.2, all Comparative Fit Index <0.47, all Tucker-Lewis Index <0.49), indicating that satisficing was not associated with DK responding. Unpredictability was associated with not knowing one's diabetes risk (OR = 1.01, P < 0.01).

LIMITATIONS

The data were cross-sectional; therefore, directionality of the pathways cannot be assumed.

CONCLUSIONS

DK responders may need more health information, but it needs to be delivered differently. Interventions might include targeting messages for lower health literacy audiences and disrupting defensive avoidance of threatening health information.

Poor Performance of Children Age 7 to 13 Years on the Newest Vital Sign

Valid and reliable instruments are needed to assess health literacy in children. Although the Newest Vital Sign (NVS) has been well established for use in adults, reports of its use in children have only recently received attention in the literature. Whereas some researchers have reported successful use of the NVS in children as young as age 7 years, others have suggested it is best used in children age 10 years and older. This analysis reports on the performance of the NVS in children age 7 to 13 years, adding to the growing evidence related to the use of the NVS in pediatric populations. Overall, children in this sample performed poorly on the NVS, which refutes previous reports. Differences in child samples and NVS administration procedures may provide some explanation for the lower-than-anticipated NVS performance in this sample. Interpreting the NVS based on educational standards and expectations may provide additional information to determine age-appropriate recommendations for NVS use in children.

Development and Validation of an Environmental Health Literacy Assessment Screening Tool for Domestic Well Owners: The Water Environmental Literacy Level Scale (WELLS)

In the U.S., privately owned wells are not subject to any regulatory testing requirements. Well owners must have sufficient environmental health literacy (EHL) to understand and interpret information that contain complex terms and labels to manage their water quality. The objective of this paper is to assess the performance and validity of a new EHL screening tool. The Water Environmental Literacy Level Scale (WELLS) is based on the Newest Vital Sign (NVS) and contains six questions on comprehension, calculations and application of information. Content validity was assessed from expert review. Criterion-related and construct validity were evaluated using an online, convenience sample of adults (n = 869). Percent of correct responses for items ranged from 53% to 96% for NVS and from 41% to 97% for WELLS. Completion time, mean scores, distributions, and internal consistency were equivalent between both scales. Higher scores suggest higher EHL. The scales were moderately correlated (ρ = 0.47, p < 0.001). Kappa agreement was 74%. Bland-Altman plots depicted little mean difference between the scales. Education and income level were positively associated with EHL. WELLS showed criterion-validity with NVS and construct validity with education and income. In practice or research, WELLS could quickly screen individuals for low EHL.

Education Milestones for Newly Diagnosed Pediatric, Adolescent, and Young Adult Cancer Patients: A Quality Improvement Initiative

The diagnosis of cancer in a child, adolescent, or young adult is an emotionally overwhelming time. To improve the quality of education and support provided to patients and caregivers with a new cancer diagnosis, we executed a quality improvement initiative to (a) define key education milestones for the delivery of essential education during the first 2 months following diagnosis and (b) to define role accountability within the multidisciplinary team for delivery of content and execution of tasks. To develop education milestones, we (a) identified educational content from review of the literature, (b) determined the sequence of content delivery through qualitative interviews with patients and caregivers, and (c) developed education milestones by evaluation of existing workflows. To develop task lists, we (a) determined which multidisciplinary team member was best suited to deliver specific content and (b) defined discrete tasks required to execute education milestones. Key content topics and preferred sequence are as follows: Emotional Adjustment to Diagnosis, When and How to Call the Doctor, Medication Management, Practical Needs, Line Care, and Access to Nontherapeutic Clinical Trials. Eight education milestones were defined across the initial 2 months following cancer diagnosis. The education milestones are paired with task lists. The education milestones and task lists guide the execution of complex education across a multidisciplinary service line in an emotionally challenging time. Early information focuses on essential content, role responsibility is clearly defined, and psychosocial support services are purposefully and iteratively integrated into care during the initial weeks following a cancer diagnosis.

Differences in Rural and Urban Health Information Access and Use

PURPOSE

Rural residents may have lower access to and use of certain health information sources relative to urban residents. We investigated differences in information source access and use between rural and urban US adults and whether having low health literacy might exacerbate rural disparities in access to and use of health information.

METHODS

Six hundred participants (50% rural) completed an online survey about access and use of 25 health information sources. We used logistic regression models to test associations between rurality and access to and use of health information sources and whether rurality interacted with health literacy to predict the access and use.

FINDINGS

Compared to urban residents, rural residents had lower access to health information from sources including primary care providers, specialist doctors, blogs, and magazines, and less use of search engines. After accounting for sociodemographics, rural residents only had lower access to specialist doctors than urban residents. Rural residents with limited health literacy had lower access to mass media and scientific literature but higher use of corporations/companies than rural residents with adequate health literacy and urban residents regardless of health literacy level.

CONCLUSIONS

Some differences in access to and use of health information sources may be accounted for by sociodemographic differences between rural and urban populations. There may be structural barriers such as shortage of specialist doctors and limited media exposure that make it harder for rural residents to access health information, especially those with limited health literacy.

A path model linking health literacy, medication self-efficacy, medication adherence, and glycemic control

OBJECTIVE

To investigate whether medication self-efficacy moderates or mediates the relationship between health literacy and medication adherence. To propose a path model that illustrates the interrelated relationship between health literacy, medication self-efficacy, medication adherence, and hemoglobin A1c (HbA1c).

METHODS

This cross-sectional study was performed via a face-to-face survey. Factors that may influence medication adherence and HbA1c were identified from the literature review. One hundred and seventy-four participants included were ≥20 years old with diagnosed type 2 diabetes, understood English, and were prescribed at least one oral diabetes medicine. During clinic visits, a questionnaire was administered to evaluate health literacy, medication self-efficacy, and medication adherence. HbA1c values were obtained from electronic medical records. Path analyses were conducted for data analysis.

RESULTS

Medication self-efficacy mediated but did not moderate the relationship between numeracy and diabetes medication adherence. Participants with higher numeracy skills may develop a greater level of medication self-efficacy, which in turn may result in a higher level of diabetes medication adherence and a lower level of HbA1c.

CONCLUSION

Enhancing patients' medication self-efficacy and numeracy skills may be imperative in intervention programs to improve diabetes medication adherence.

PRACTICE IMPLICATIONS

An improvement in numeracy skills and medication self-efficacy is recommended to enhance diabetes medication adherence.

Measuring Nutrition and Food Literacy in Adults: A Systematic Review and Appraisal of Existing Measurement Tools

Background:

Nutrition literacy (NL) and food literacy (FL) have emerged as key components in the promotion and maintenance of healthy dietary practices. However, a critical appraisal of existing tools is required to advance the operationalization and measurement of these constructs using instruments that demonstrate sound validity and reliability.

Methods:

Electronic databases were searched in January and July 2016, January 2017, and March 2018 for publications detailing the development and/or testing of NL or FL instruments. Instruments' psychometric properties were assessed using a structured methodological framework. We identified 2,563 new titles and abstracts, and short-listed 524 for full review. The extent to which key domains of NL were included in each measure was examined.

Key Results:

Thirteen instruments assessing NL underwent full evaluation; seven from the United States, and one each from Australia, Norway, Switzerland, Italy, Hong Kong, and Japan. Measures targeted general Spanish-, Italian-, or Cantonese-speaking adults; primary care patients, parent, and populations with breast cancer. Instruments ranged from 6 to 64 items, and they predominantly assessed functional NL rather than broader domains of NL. Substantial variation in methodological rigor was observed across measures.

Discussion:

Multidimensional and psychometrically sound measures that capture broader domains of NL and assess FL are needed.

Plain Language Summary:

This review systemically compiles, and critically appraises 13 existing measures that assess nutrition literacy and food literacy in an adult population. Substantial variation in methodological rigor was found across the measures, and most tools assessed nutrition literacy rather than food literacy. Findings from this current review may be useful to guide development of future measures that comprehensively capture nutrition literacy and food literacy. [HLRP: Health Literacy Research and Practice. 2018;2(3):e134–e160.]

A Preliminary Study of Health Literacy in an Ethnically Diverse University Sample

There is a considerable body of research on health literacy in adult healthcare settings, mostly among at-risk clinical populations. However, much less is known about health literacy among youth transitioning to adulthood, including college students. Despite the protective effects of higher levels of education, some college students might have other risk factors for low health literacy (i.e., minority status). Hence, the purpose of the present study was to explore health literacy in an ethnically diverse public urban university. Although a majority of the students performed within the adequate range, we observed a subset of Hispanic and foreign students with lower health literacy, particularly in the domain of numeracy. Our preliminary results suggest that, contrary to common belief, there exists a vulnerable subpopulation of college students that have difficulty understanding and using health-related information. Health professionals should be alert to possible low health literacy among college students that may interfere with communication of vital health-related information and decision-making.

Health Literacy, Glycemic Control, and Physician-Advised Glucose Self-Monitoring Use in Type 2 Diabetes

Objective

To measure the association between health literacy and both patient-reported and clinical outcomes in patients with non-insulin-treated type 2 diabetes.

Research Design and Methods

We surveyed patients with non-insulin-treated type 2 diabetes (n = 448) from 15 primary care practices. The association between health literacy and patient-reported and clinical outcomes, including numeracy of self-monitoring of blood glucose (SMBG) use, how often physicians advised patients to conduct SMBG testing, and glycemic control (as measured by A1C), was investigated.

Results

Study participants included 448 patients with non-insulin-treated type 2 diabetes located within central North Carolina. Participants with limited health literacy had poorer glycemic control (A1C 7.7 ± 1.1% vs. 7.5 ± 1.0%, P = 0.016) despite using SMBG testing more frequently (daily SMBG testing 49.3 vs. 30.7%, P = 0.001) compared to individuals with adequate health literacy. The difference in how often physicians advised patients to conduct SMBG testing between limited and adequate health literacy groups was not significant (P = 0.68).

Conclusion

Limited health literacy was associated with poorer glycemic control and an increased frequency of SMBG testing in patients with non-insulin-treated type 2 diabetes. There was no significant difference in how often physicians advised patients to conduct SMBG testing between patients with limited and adequate health literacy.

The position of a written document in preoperative information for pediatric surgery: A randomized controlled trial on parental anxiety, knowledge, and satisfaction

INTRODUCTION

Preoperative information is a legal and ethical obligation. Very little studies have evaluated the preoperative information method in pediatrics. Having a child operated on is stressful for the parents. Improving information is a way to lower their anxiety. Our study aims to measure the impact of a leaflet, which supports spoken information on parental anxiety, the comprehension-memorization of the information and their satisfaction.

MATERIALS & METHODS

Prospective study including 178 patients of outpatient surgery, randomized in two groups: spoken information versus spoken information supported by a leaflet, which is then handed out to the parents. The messages were identical: physiopathology, risks without treatment, surgical technique and its possible complications, description of the hospitalization day, and postoperative care. Parental evaluation was made with self-questionnaires after the preoperative consultation, then on the day of surgery. At each moment we evaluated the level of anxiety, satisfaction of information quality and the comprehension-memorization of the data.

RESULTS

Written information significantly improves the scores of comprehension-memorization, parental satisfaction and significantly decreases the level of anxiety.

CONCLUSION

Significant impact of the written document as communication support in pediatric surgery, validating the method and encouraging it to be generalized to other pediatric surgery acts.

LEVEL OF EVIDENCE

Validation of a newly adapted Chinese version of the Newest Vital Sign instrument

OBJECTIVE

To develop a Chinese version of the Newest Vital Sign (NVS-CHN) instrument and evaluate its psychometric properties.

METHODS

To deal with cross-cultural adaptation problems, after translation of the NVS into Chinese, the Delphi method was used for experts and cognitive testing was used for participants. A cross-sectional study including 351 participants was conducted to assess the validity of the NVS-CHN. Internal reliability, criterion validity, and known-groups validity were investigated. The NVS-CHN was further validated against a suitable standard, the Chinese Citizen Health Literacy Questionnaire (CCHLQ).

RESULTS

The validity of the NVS-CHN was established by conducting a Delphi survey (three rounds) and cognitive testing (three rounds). Cronbach's alpha was 0.71, indicating that internal consistency was acceptable. A Spearman's correlation coefficient of 0.68 between the NVS-CHN and CCHLQ revealed excellent criterion validity. Differences in NVS-CHN scores by education level confirmed known-groups validity. A receiver operating characteristics analysis showed that the area under the curve was 0.81, indicating that the NVS-CHN was an accurate health literacy assessment tool. A score ≥ 4 out of 6 best identified participants with adequate health literacy.

CONCLUSIONS

The NVS-CHN has excellent psychometrical reliability and validity, which make it a suitable tool to evaluate health literacy in China.

Association of health literacy and medication self-efficacy with medication adherence and diabetes control

INTRODUCTION

The exact pathway linking health literacy, self-efficacy, medication adherence, and glycemic control for type 2 diabetes remains unclear. Understanding the relationship between patient factors, medication adherence, and lower glycated hemoglobin (HbA1c) may help patients better manage their disease. This study examined the association of health literacy and medication self-efficacy with self-reported diabetes medication adherence, and the association of health literacy, medication self-efficacy, and self-reported diabetes medication adherence with HbA1c of patients with type 2 diabetes.

METHODS

This cross-sectional study utilized a face-to-face questionnaire at two family medicine clinics in a Midwestern state among 174 patients; subjects enrolled were at least 20 years old with diagnosed type 2 diabetes, prescribed at least one oral diabetes medicine, and understood English. Questionnaires were administered to assess the participants': health literacy, using the Newest Vital Sign six-item questionnaire (NVS); self-efficacy for medication use, using the 13-item Self-Efficacy for Appropriate Medication Use Scale; and self-report medication adherence, using the eight-item Morisky Medication Adherence Scale. HbA1c values were obtained from participants' electronic medical records. Multiple linear regressions were used to explore the association of health literacy and medication self-efficacy with both medication adherence and HbA1c level after controlling for all other covariates.

RESULTS

Self-reported health status (β = 0.17, p = 0.015) and medication self-efficacy (β = 0.53, p < 0.001) were positively associated with diabetes medication adherence. Health literacy was neither associated with diabetes medication adherence (β = -0.04, p = 0.586) nor HbA1c (β = -0.06, p = 0.542). Lower diabetes medication adherence (β = -0.26, p = 0.008) and higher number of prescribed medications (β = 0.28, p = 0.009) were correlated with higher HbA1c.

CONCLUSION

Health literacy, as measured by the NVS, does not correlate with medication adherence or glycemic control among patients with type 2 diabetes. Interventions to improve patients' self-efficacy of medication use may improve diabetes medication adherence.

Quick screen of patients' numeracy and document literacy skills: the factor structure of the Newest Vital Sign

INTRODUCTION

The Newest Vital Sign (NVS) is a survey designed to measure general health literacy whereby an interviewer asks six questions related to information printed on a nutritional label from an ice cream container. It enables researchers to evaluate several health literacy dimensions in a short period of time, including document literacy, comprehension, quantitative literacy (numeracy), application, and evaluation. No study has empirically examined which items belong to which latent dimensions of health literacy in the NVS using factor analysis. Identifying the factor structure of the NVS would enable health care providers to choose appropriate intervention strategies to address patients' health literacy as well as improve their health outcomes accordingly. This study aimed to explore the factor structure of the NVS that is used to assess multiple dimensions of health literacy.

METHODS

A cross-sectional study administering the NVS in a face-to-face manner was conducted at two family medicine clinics in the USA. One hundred and seventy four individuals who participated were at least 20 years old, diagnosed with type 2 diabetes, prescribed at least one oral diabetes medicine, and used English as their primary language. Exploratory factor analysis and confirmatory factor analysis were conducted to investigate the factor structure of the NVS.

RESULTS

Numeracy and document literacy are two dimensions of health literacy that were identified and accounted for 63.05% of the variance in the NVS. Internal consistency (Cronbach's alpha) of the NVS were 0.78 and 0.91 for numeracy and document literacy, respectively.

CONCLUSION

Numeracy and document literacy appropriately represent the factor structure of the NVS and may be used for assessing health literacy in greater detail for patients with type 2 diabetes.

Health Literacy and Use and Trust in Health Information

There is a need to investigate which health information sources are used and trusted by people with limited health literacy to help identify strategies for addressing knowledge gaps that can contribute to preventable illness. We examined whether health literacy was associated with people's use of and trust in a range of potential health information sources. Six hundred participants from a GfK Internet survey panel completed an online survey. We assessed health literacy using the Newest Vital Sign, the sources participants used to get health information, and the extent to which participants trusted health information from these sources. We performed multivariable regressions, controlling for demographic characteristics. Lower health literacy was associated with lower odds of using medical websites for health information and with higher odds of using television, social media, and blogs or celebrity webpages. People with lower health literacy were less likely to trust health information from specialist doctors and dentists, but more likely to trust television, social media, blogs/celebrity webpages, friends, and pharmaceutical companies. People with limited health literacy had higher rates of using and trusting sources such as social media and blogs, which might contain lower quality health information compared to information from healthcare professionals. Thus, it might be necessary to enhance the public's ability to evaluate the quality of health information sources. The results of this study could be used to improve the reach of high-quality health information among people with limited health literacy and thereby increase the effectiveness of health communication programs and campaigns.

Is the Newest Vital Sign a Useful Measure of Health Literacy in HIV Disease?

BACKGROUND

Limited health literacy is common among persons infected with HIV and has been linked to poor mental and physical health outcomes, but there are no well-validated screening measures of health literacy in this vulnerable clinical population. The present study evaluates the usefulness of the Newest Vital Sign (NVS) as a brief measure of health literacy in HIV disease.

METHODS

Seventy-eight HIV+ adults were administered the NVS, Rapid Estimate of Adult Literacy in Medicine (REALM), and Single Item Literacy Screener (SILS). Main criterion variables included plasma HIV viral load, medication management capacity, self-efficacy for medication management, and perceived relationships with healthcare providers.

RESULTS

The NVS showed good internal consistency and moderate correlations with the REALM and SILS. Rates of limited health literacy were highest on the NVS (30.3%) as compared to SILS (6.6%) and REALM (9.2%). A series of regressions controlling for education showed that the NVS was incrementally predictive of viral load, medication management capacity and self-efficacy, and relationships with healthcare providers, above and beyond the REALM and SILS.

CONCLUSION

The NVS shows evidence of reliability, convergent validity, and incremental criterion-related validity and thus may serve as useful screening tool for assessing health literacy in HIV disease.

Influence of health literacy and trust in online information on food allergy quality of life and self-efficacy

BACKGROUND

Health literacy among caregivers of food allergic individuals (FAIs) is poorly described, as are the information sources sought regarding food allergy.

OBJECTIVE

To assess the association among health literacy, trust in online sources of information, and food allergy quality of life (QoL) and self-efficacy.

METHODS

An online survey was administered to caregivers of FAIs assessing health literacy (Newest Vital Sign [NVS] and the eHeals Internet health literacy index), trust in online information (Hargittai Internet credibility index and Annenberg National Health Communication Survey [ANHCS]), QoL (Food Allergy Quality of Life Parental Burden), and self-efficacy (Food Allergy Self-Efficacy Questionnaire [FASEQ]).

RESULTS

Among 1562 respondents, 94.6% (NVS) and 61.1% (eHeals) had good health literacy, and 58% had high levels of trust in online information (both indexes). The NVS correlated poorly with the eHeals and Hargittai indexes. Hargittai and eHeals scores were moderately correlated (r = 0.37, P < .001). A high NVS score was significantly associated with reported anaphylaxis and high eHeals and Hargittai scores with advocacy group membership. In unadjusted analyses, FAQL-PB scores were worse with high Hargiatti scores (P = .05) and ANHCS scores (P < .001). The FASEQ scores were better with high ANHCS scores (P = .02) and eHeals scores (P < .001). In an adjusted regression, high trust in online information (both indexes), worsening FASEQ score, blog readership, advocacy group membership, caring for multiple FAIs, and having milk or egg allergy were associated with worse FAQL-PB scores.

CONCLUSION

In this sample, health literacy and trust in online information sources were high, with high trust in online information sources negatively associated with QoL. Advocacy group membership had an independent negative association with QoL.

Hemodialysis Access Choice: Impact of Health Literacy

BACKGROUND

Hemodialysis patients need to make decisions about vascular access and diet that they may not fully understand. In this study, we hypothesized that patients with low health literacy are likely to choose a central venous catheter (CVC) and have higher serum potassium (K), serum phosphate (P), and inter-dialysis weight gains (IDWG).

OBJECTIVE

Primarily, the study sought to describe the health literacy of patients treated with hemodialysis in a Canadian tertiary care center. The secondary objective was to describe the association between health literacy and permanent vascular access choice, hyperkalemia, hyperphosphatemia, and IDWG.

METHODS

Adult patients receiving hemodialysis for more than 6 months were included. Health literacy was assessed with the Newest Vital Sign (NVS) test. Vascular access type and reasons for CVC use were determined. Serum K, P, and IDWG were collected retrospectively for 6 months. Student's t test and logistic regression were used to determine the association between health literacy (NVS score < 4 versus ≥ 4) and CVC choice, hyperkalemia, hyperphosphatemia, and high IDWG.

KEY RESULTS

Fifty-six patients were involved. The average NVS score was 2.9. Overall, 66% of the patients had a CVC; one-third had chosen this access themselves. Poor control of K, P, and IDWG was experienced by 27%, 55%, and 36% of patients, respectively. The average NVS score was lower for patients choosing a CVC (p = .001), but not different for those with higher K, P, or IDWG. None of the patients who chose a CVC had adequate health literacy (NVS ≥ 4).

CONCLUSIONS

Patients with low health literacy, who are eligible for both surgically created vascular access (fistula or graft) and CVC, are more likely to refuse fistula/graft creation compared to patients with adequate health literacy. Different educational strategies for such patients may help in appropriate decision-making. [Health Literacy Research and Practice. 2017;1(3):e136-e144.].

PLAIN LANGUAGE SUMMARY

This study suggests that more than one-half of patients who receive hemodialysis may not understand all the information provided by their health care team. Despite a higher risk of complications with a central venous catheter, patients with lower health literacy prefer the catheter over fistula as their blood access for hemodialysis. We need to explore patient education to ensure that information is easy to understand.

The missing link to patient engagement in Italy

Purpose The purpose of this paper is to discuss the changing patterns of users' behavior in the health care service system. Although patient engagement and health services' co-production are understood as essential ingredients in the recipe for sustainable health systems, some determinants to patient involvement are still widely neglected by both policy makers and health care professionals. Among others, inadequate health literacy performs as a significant barrier to patient empowerment. Design/methodology/approach A survey aimed at objectively measuring health literacy-related skills was administered to a random sample of 600 Italian patients. The Italian version of the Newest Vital Sign (NVS) was used to assess the ability of the respondents to deal with written health information. Moreover, the respondents were asked to self-report their ability to navigate the health system. It was presumed that inadequate health literacy as measured by the NVS is related with impaired self-reported functional, interactive, and critical health-related competencies, paving the way for the inability and the unwillingness of patients to be involved in the health care provision. Findings About half of the sample showed inadequate health literacy. However, poor NVS scores were only slightly associated with limited self-reported functional, interactive, and critical health-related competencies. In general, patients with inadequate health-related skills were not likely to be engaged in the provision of health services. Elderly, people suffering from financial deprivation and less educated individuals were found to be at special risk of living with limited health literacy. Practical implications Limited health literacy is a common and relevant issue among people dealing with the health care service system. The impaired ability to collect, process, and use health information produces barriers to patient engagement and prevents the evolution of patients' behavior toward health care co-production. Originality/value Health literacy is a widely overlooked issue in the Italian national health system. This paper contributes in shedding light on the determinants and effects of health literacy of Italian hospital patients. Besides, some insights on the validity of the methodological tools typically used to assess health-related skills are provided.

Self-Administered Assessment of Health Literacy in Adolescents Using the Newest Vital Sign

The “Newest Vital Sign” (NVS) is a validated health literacy assessment tool typically administered by clinicians. The objective of this study was to assess if the NVS could be self-administered in adolescents to measure health literacy. Sixth graders in a Colorado middle school were provided a self-administered survey containing the NVS, a section for parent permission, and a section for the student’s age, gender, grade, and previous elementary school. In all, 167 sixth graders returned usable surveys (45% return rate), and the average health literacy score was 3.75 ± 1.70. Almost two thirds (62.9%) of the students scored in the adequate health literacy range, while only 12.6% scored in the limited health literacy range. Health literacy scores were similar when evaluated based on gender. However, when students were grouped based on prior elementary school attendance, students who matriculated from one elementary school had an average NVS score significantly lower than two other elementary schools (p < .001 and p < .05). Self-administration of the NVS was successful and showed similar health literacy scores compared to other studies in adolescents. Using the NVS as a self-administered tool could greatly increase its function as a quick health literacy assessment for adolescents, both in clinical practice and in school-based health education.
