- Active and healthy aging after COVID-19 pandemic in Portugal and other European countries: time to rethink strategies and foster actionPublication . Costa, Andreia; Camara, Gisele; Arriaga, Miguel Telo de; Nogueira, Paulo; Miguel, José PereiraThe population aging in Europe imposes challenges to societies that require adaptations and responses at various levels to minimize impacts and figuring out opportunities. Portugal has been committed to the World Health Organization and European Union's values and policy frameworks concerning active and healthy aging. In 2017, an inter-ministerial working group developed the National Strategy for Active and Healthy Aging. In the face of the COVID-19 pandemic that exposed the vulnerabilities of older populations, the launch of the Decade of Healthy Aging 2021-2030 and its baseline report and the 2018 Active Aging Index Analytical Report may constitute an opportunity to strategically think about the aging of the population as a national purpose in Portugal and in the other European countries that face similar challenges.
- Crises social sensing: longitudinal monitoring of social perceptions of systemic risk during public health crisisPublication . Gaspar, Rui; Domingos, Samuel; Toscano, Hugo; Filipe, Jessica; Leiras, Gisela; Raposo, Beatriz; Pereira, Cícero; Godinho, Cristina; Francisco, Rita; Silva, Claudia; Arriaga, Miguel Telo deMonitoring how different people – as ‘social sensors’ – evaluate and respond to crisis such as pandemics, allows tailoring crisis communication to the social perceptions of the situation, at different moments. To gather such evidence, we proposed a index of social perceptions of systemic risk (SPSR), as an indicator of a situational threat compromising risks to physical health, psychological health, the economy, social relations, health system, and others. This indicator was the core of a social sensing approach applied to crisis situations, implemented during the COVID-19 pandemic through a content analysis of more than 130.000 public comments from Facebook™ users, in COVID-19 related publications. This content coding allowed creating a SPSR index monitored during a one-year descriptive longitudinal analysis. This index correlated with co-occurring events within the social system, namely epidemiological indicators across measurement cycles (e.g. new deaths; cumulative number of infection cases; Intensive Care Unit hospitalizations) and tended to reflect the epidemiological situation severity (e.g. with the highest level registered during the worst pandemic wave). However, discrepancies also occurred, with high SPSR registered in a low severity situation, i.e. low number of hospitalizations and deaths (e.g. school year beginning), or low SPSR in a high severity situation (e.g. 2nd pandemic wave during Christmas), showing other factors beyond the epidemiological situation contributing to the social perceptions. After each ‘crisis period’ with SPSR peaking, there was a ‘restoration period’, consistently decreasing towards average levels of the previous measurement cycle. This can either indicate social resilience (recovery and resources potentiation) or risk attenuation after a high-severity period. This study serves as preliminary proof of concept of a crises social sensing approach, enabling monitoring of social system dynamics for various crisis types, such as health crisis or the climate crisis.
- From health communication to health literacy: a comprehensive analysis of relevance and strategiesPublication . Caeiros, Patrícia; Ferreira, Patrícia Pita; Chen-Xu, Jose; Francisco, Rita; Arriaga, Miguel Telo deHealth literacy, the ability to obtain and comprehend health knowledge, is essential to promote health and reduce disparities. Health communication aims to improve health by ensuring an effective understanding and application of health information. Despite current challenges, there are many opportunities for improving communication in the health literacy practice. Promoting communication in health literacy is essential in empowering individuals, improving outcomes, and reducing healthcare disparities. Effective communication enables access, comprehension, and informed decision-making of individuals and communities regarding their health, strengthening their central role in promoting health literacy. This paper highlights the challenges and opportunities in today's world, especially in a post-pandemic era, dominated by infodemic and social media influencers, while providing solutions, encompassing professional training of health professionals on communication, digital skills, and an overarching strategy across health institutions. Translating knowledge into health-promoting behaviors and well-being can only be effective by accounting for communication in health literacy.
- HLS19-NAV - validation of a new instrument measuring navigational health literacy in eight European countriesPublication . on behalf of the HLS Consortium; Griese, Lennert; Finbråten, Hanne S.; Francisco, Rita; Gani, Saskia M. de; Griebler, Robert; Guttersrud, Øystein; Jaks, Rebecca; Le, Christopher; Link, Thomas; Costa, Andreia Silva da; Arriaga, Miguel Telo de; Touzani, Rajae; Vrdelja, Mitja; Pelikan, Jürgen M.; Schaeffer, DorisTo manoeuvre a complex and fragmented health care system, people need sufficient navigational health literacy (NAV-HL). The objective of this study was to validate the HLS19-NAV measurement scale applied in the European Health Literacy Population Survey 2019–2021 (HLS19). From December 2019 to January 2021, data on NAV-HL was collected in eight European countries. The HLS19-NAV was translated into seven languages and successfully applied in and validated for eight countries, where language and survey method differed. The psychometric properties of the scale were assessed using confirmatory factor analysis (CFA) and Rasch modelling. The tested CFA models sufficiently well described the observed correlation structures. In most countries, the NAV-HL data displayed acceptable fit to the unidimensional Rasch partial credit model (PCM). For some countries, some items showed poor data–model fit when tested against the PCM, and some items displayed differential item functioning for selected person factors. The HLS19-NAV demonstrated high internal consistency. To ensure content validity, the HLS19-NAV was developed based on a conceptual framework. As an estimate of discriminant validity, the Pearson correlations between the NAV-HL and general health literacy (GEN-HL) scales were computed. Concurrent predictive validity was estimated by testing whether the HLS19-NAV, like general HL measures, follows a social gradient and whether it forms a predictor of general health status as a health-related outcome of general HL. In some countries, adjustments at the item level may be beneficial.
