HLS19-NAV-Validation of a New Instrument Measuring Navigational Health Literacy in Eight European Countries

Associations between digital health literacy and health system navigating abilities among Norwegian adolescents: validating the HLS19-DIGI scale using Rasch modeling

BACKGROUND

Despite increasing global attention to health literacy and adolescents' digital health information seeking, no unidimensional instruments measuring digital health literacy (DHL) in adolescents have reportedly been validated using Rasch modeling. Moreover, the evidence of adolescents' abilities to navigate the health system (NAV-HL) in light of their DHL proficiency is still scarce. Therefore, our study aims to evaluate the psychometric properties of a DHL instrument (HLS19-DIGI scale) in order to investigate DHL in adolescents and young adults aged 16-25 and associations with abilities to navigate the health system.

METHODS

A population-based cross-sectional survey among 890 Norwegian adolescents was conducted during April-October 2020 using computer-assisted telephone interviewing. Rasch modeling, independent samples t-test, chi-square test, and binary regression models were used to analyze the data.

RESULTS

The HLS19-DIGI scale was sufficiently unidimensional, whereas no differential item functioning or disordered response categories were observed. However, relatively poor targeting was revealed indicating too many easy items for the target population. Yet, a high proportion (54%) of low DHL proficiency in adolescents was observed, as well as DHL was positively associated with the abilities to navigate the health system.

CONCLUSIONS

The HLS19-DIGI scale is considered a sufficiently unidimensional and valid instrument for measuring DHL in adolescents, which may be a useful tool for health authorities, public health workers, and health service providers. While DHL affects adolescents' abilities to navigate the health system, future research should measure and examine their ability to utilize digital health services, separately.

General, Vaccination, Navigational and Digital Health Literacy of Students Enrolled in Different Medical and Health Educational Programs

Evaluating prospective graduates' health literacy profiles before they enter the job market is crucial. Our research aimed to explore the health literacy levels of medical and health students by assessing their ability to obtain health-related information, understand healthcare systems, use e-health, and be informed about vaccination as well as to explore the factors associated with health literacy. Short versions of the HLS19-Q12 were used for a cross-sectional survey that was carried out among 1042 students enrolled in various medical and health educational programs at three medical universities in Kazakhstan between September and November of 2023. Additionally, instruments such as Digital Health Literacy (HLS19-DIGI), Navigational Health Literacy (HLS19-NAV), and Vaccination Health Literacy (HLS19-VAC) were employed. The score of General Health Literacy was 88.26 ± 17.5. One in eight students encountered difficulties in Vaccination Health Literacy. Despite overall high health literacy, Navigational Health Literacy posed challenges for all students. The Public Health students exhibited the highest General Health Literacy (91.53 ± 13.22), followed by students in Nursing, General Medicine, other educational programs (Dentistry and Biomedicine) and Pharmacy. Financial constraints for medication and medical examinations significantly influenced health literacy across all types of individuals. Since comprehensive health literacy instruction or interventions are still uncommon in the curricula, it seems reasonable to develop and incorporate appropriate courses for medical and health educational programs.

Variations in the intended utilization of emergency care in case of gastrointestinal diseases

Frequent utilization of emergency care and overcrowded emergency departments (EDs) are highly relevant topics due to their harmful consequences for patients and staff. The present study examines variations of intended health care use in urgent and non-urgent cases among the general population. In a cross-sectional telephone survey, a sample of N = 1,204 adults residing in Hamburg, Germany, was randomly drawn. At the beginning of the survey, one of 24 different vignettes (case stories) describing symptoms of inflammatory gastrointestinal diseases were presented to the participants. The vignettes varied in sex (male/female), age (15, 49, 72 years), daytime (Tuesday morning, Tuesday evening), and urgency (low, high). Participants were asked in an open-ended question about their primal intended utilization if they or their children would be affected by such symptoms. Overall, about 14 % chose emergency facilities (ED, ambulance, emergency practice) despite presentation of non-urgent conditions (n = 602). Intended emergency care use varied considerably even if the degree of urgency was comparable. Adolescence, male sex, and symptoms occurring in the evening were associated with increased ED and ambulance use. Inappropriate utilization of ED and ambulance (analyses regarding utilization due to non-urgent problems) was more often observed among male respondents and those with a migration background (1st generation). Information campaigns focused on emergency care use and reorganisation of emergency care wards are possible interventions.

[Navigational health literacy of the population in Germany]

AIM

Many health care systems are characterized by their high complexity and intransparency. Finding one's way through the multitude of services and finding the right place requires high navigational health literacy (NHL). NHL is defined as the ability to manoeuvre through the health care system and deal with the information required to do so. However, so far, there has been a lack of data on the population's NHL. The objective of this article is to analyse empirically the NHL in Germany and its association with socio-demographic and economic factors.

METHOD

NHL was surveyed with an instrument (HLS19-NAV) newly developed by an international working group, measuring the self-assessed difficulties in relation to 12 navigation-related information tasks. The HLS19-NAV has already been used in 8 countries, including Germany. In Germany, data on NHL was collected from 2,151 adult residents in a representative cross-sectional study. The relationship between socio-demographic and economic factors, and NHL was examined by using methods of analysis of variance and multivariate linear regression analysis.

RESULTS

Approximately 80% of the respondents showed low NHL with a mean score of 41.5 out of a possible 100 points. Those with low socio-economic resources, people of advanced age, people who had migrated to Germany or who were limited by health issues had a particularly low NHL. However, even people with good resources had a relatively low NHL. In contrast, the mean score was significantly higher among health professionals.

CONCLUSIONS

In recent years, numerous efforts have been made to reduce navigational difficulties and to better guide patients through the German health care system. However, according to the results of the study, there is still need for further action. Above all, structural measures are required: this includes the creation of sufficient, reliable information on the health care system and its organizations as well as the implementation of navigation aids, health care pathways and the creation of a health-literate health care system including organizations and health professionals that contribute to strengthening NHL in general.

Health literacy and the role of social support in different age groups: results of a German cross-sectional survey

BACKGROUND

Scholars demand more focus on context-related factors of health literacy as the management of health information is seen as a social practice. One prominent factor is social support that is expected to be particularly relevant for persons vulnerable for low health literacy. It was shown that health literacy can differ across the life span and especially older people have been demonstrated to be vulnerable for low health literacy. Therefore, health literacy and the relation of social support on health literacy in different age groups should be investigated.

METHODS

In a German nationwide survey 2,151 adults were interviewed face-to-face. General comprehensive health literacy was measured with the HLS19-Q47 which differentiates single steps of health information management - access, understand, appraise, and apply. Social support was measured with the Oslo 3 Social Support Scale. Bivariate and multivariate analyses were performed for all respondents and for five age groups.

RESULTS

Health literacy is relatively low in all age groups but particularly low among old-old people (76 + years). Also, the youngest adults (18-29 years) have slightly lower health literacy than middle-aged adults. On average, health literacy is higher among people with higher social support but this association varies between age groups. It tends to be quite strong among younger adults (18-45 years) and young-old persons (65-75 years) but is weak among older middle-aged (46-64 years) and old-old persons. The association also differs between steps of information management. It is stronger for accessing and applying information but there are differences in age groups as well.

CONCLUSIONS

Social support is a relevant aspect to improve individuals' health literacy and therefore should be addressed in interventions. However, it is necessary to differentiate between age groups. While both young adults and particularly old-old persons are challenged by health information management, young adults can strongly profit from social support whereas it can barely compensate the low health literacy of old-old persons. In addition, different challenges in information management steps in different age groups need to be considered when designing health literacy interventions. Thus, target group specific services and programs are needed.
