BackgroundRecent advances in the measurement of health literacy allow description of a broad range of personal and social dimensions of the concept. Identifying differences in patterns of health literacy between population sub-groups will increase understanding of how health literacy contributes to health inequities and inform intervention development. The aim of this study was to use a multi-dimensional measurement tool to describe the health literacy of adults in urban and rural Victoria, Australia.MethodsData were collected from clients (n = 813) of 8 health and community care organisations, using the Health Literacy Questionnaire (HLQ). Demographic and health service data were also collected. Data were analysed using descriptive statistics. Effect sizes (ES) for standardised differences in means were used to describe the magnitude of difference between demographic sub-groups.ResultsMean age of respondents was 72.1 (range 19–99) years. Females comprised 63 % of the sample, 48 % had not completed secondary education, and 96 % reported at least one existing health condition. Small to large ES were seen for mean differences in HLQ scales between most demographic groups. Compared with participants who spoke English at home, those not speaking English at home had much lower scores for most HLQ scales including the scales ‘Understanding health information well enough to know what to do’ (ES −1.09 [95 % confidence interval (CI) -1.33 to −0.84]), ‘Ability to actively engage with healthcare providers’ (ES −1.00 [95 % CI −1.24, −0.75]), and ‘Navigating the healthcare system’ (ES −0.72 [95 % CI −0.97, −0.48]). Similar patterns and ES were seen for participants born overseas compared with those born in Australia. Smaller ES were seen for sex, age group, private health insurance status, number of chronic conditions, and living alone.ConclusionsThis study has revealed some large health literacy differences across nine domains of health literacy in adults using health services in Victoria. These findings provide insights into the relationship between health literacy and socioeconomic position in vulnerable groups and, given the focus of the HLQ, provide guidance for the development of equitable interventions.
BackgroundThe need for healthcare strengthening to enhance equity is critical, requiring systematic approaches that focus on those experiencing lesser access and outcomes. This project developed and tested the Ophelia (OPtimising HEalth LIteracy and Access) approach for co-design of interventions to improve health literacy and equity of access. Eight principles guided this development: Outcomes focused; Equity driven, Needs diagnosis, Co-design, Driven by local wisdom, Sustainable, Responsive and Systematically applied. We report the application of the Ophelia process where proof-of-concept was defined as successful application of the principles.MethodsNine sites were briefed on the aims of the project around health literacy, co-design and quality improvement. The sites were rural/metropolitan, small/large hospitals, community health centres or municipalities. Each site identified their own priorities for improvement; collected health literacy data using the Health Literacy Questionnaire (HLQ) within the identified priority groups; engaged staff in co-design workshops to generate ideas for improvement; developed program-logic models; and implemented their projects using Plan-Do-Study-Act (PDSA) cycles. Evaluation included assessment of impacts on organisations, practitioners and service users, and whether the principles were applied.ResultsSites undertook co-design workshops involving discussion of service user needs informed by HLQ (n = 813) and interview data. Sites generated between 21 and 78 intervention ideas and then planned their selected interventions through program-logic models. Sites successfully implemented interventions and refined them progressively with PDSA cycles. Interventions generally involved one of four pathways: development of clinician skills and resources for health literacy, engagement of community volunteers to disseminate health promotion messages, direct impact on consumers’ health literacy, and redesign of existing services. Evidence of application of the principles was found in all sites.ConclusionsThe Ophelia approach guided identification of health literacy issues at each participating site and the development and implementation of locally appropriate solutions. The eight principles provided a framework that allowed flexible application of the Ophelia approach and generation of a diverse set of interventions. Changes were observed at organisational, staff, and community member levels. The Ophelia approach can be used to generate health service improvements that enhance health outcomes and address inequity of access to healthcare.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-017-4147-5) contains supplementary material, which is available to authorized users.
The Health Literacy Questionnaire (HLQ), developed in Australia in 2012 using a ‘validity-driven’ approach, has been rapidly adopted and is being applied in many countries and languages. It is a multidimensional measure comprising nine distinct domains that may be used for surveys, needs assessment, evaluation and outcomes assessment as well as for informing service improvement and the development of interventions. The aim of this paper is to describe the German translation of the HLQ and to present the results of the validation of the culturally adapted version. The HLQ comprises 44 items, which were translated and culturally adapted to the German context. This study uses data collected from a sample of 1,058 persons with chronic conditions. Statistical analyses include descriptive and confirmatory factor analyses. In one-factor congeneric models, all scales demonstrated good fit after few model adjustments. In a single, highly restrictive nine-factor model (no cross-loadings, no correlated errors) replication of the original English-language version was achieved with fit indices and psychometric properties similar to the original HLQ. Reliability for all scales was excellent, with a Cronbach’s Alpha of at least 0.77. High to very high correlations between some HLQ factors were observed, suggesting that higher order factors may be present. Our rigorous development and validation protocol, as well as strict adaptation processes, have generated a remarkable reproduction of the HLQ in German. The results of this validation provide evidence that the HLQ is robust and can be recommended for use in German-speaking populations.Trial Registration: German Clinical Trial Registration (DRKS): DRKS00000584.

The nine HLQ scales are robust, providing a fine-grained assessment of health literacy. The revised response options improve psychometric properties and are recommended for future studies.
Objectives:Health literacy refers to the ability of individuals to gain access to, use, and understand health information and services in order to maintain a good health. The assessment of health literacy profiles in a population is potentially crucial to respond to health needs. The Health Literacy Questionnaire explores nine dimensions of health literacy and has been shown to display robust psychometric properties. The aim was to test the validity of the multidimensional Health Literacy Questionnaire and to describe the health literacy profiles in a French population at risk of cardiovascular disease.Methods:Data were collected using self-administered questionnaires from 175 participants attending health education and support programmes in local associations of patients in Paris. Analysis included scale reliability, confirmatory factor analysis, and health literacy profiles via descriptive statistics.Results:In confirmatory factor analysis, the nine-factor structure was close to the original Health Literacy Questionnaire. A nine-factor confirmatory factor analysis model was fitted to the 44 items with no cross-loadings or correlated residuals allowed. Given the restricted nature of the model, the fit was satisfactory: χ2WLSMV(866 df) = 1383.81, p = 0.0000, comparative fit index = 0.925, Tucker–Lewis index = 0.918, root mean square error of approximation = 0.058, weighted root mean square residual = 1.175. Composite reliability ranged from 0.77 to 0.91. Among the 9 scales of the Health Literacy Questionnaire, the highest scores were found for scale 1 ‘Feeling understood and supported by healthcare professionals’ and scale 9 ‘Understand health information enough to know what to do’ and the lowest for scale 2 ‘Having sufficient information to manage my health’ and scale 7 ‘Navigating the healthcare system’.Conclusion:The French version of the Health Literacy Questionnaire was shown to be psychometrically robust with good reliability. In the context of France, the 9 scales of Health Literacy Questionnaire allow a thorough assessment of health literacy strengths and weaknesses to respond to health literacy needs and improve the accessibility of health information and services.
