In the field of risks and crises, both the access to relevant information and its circulation are seen as crucial factors. Based on a new integrated theoretical model focusing on the stakeholder, the book proposes analysis of information reformulation and circulation in risk environments and crisis situations. Simply circulating the information does not mean that it will be picked up by those who could benefit from it. This has been amply demonstrated by the various crises and catastrophes that have shaken the planet in recent years. In order to be able to deal with risk situations and crises, it must be possible for information ? when it circulates ? to be understood and interpreted by a wide range of stakeholders, working in fields such as health and natural or environmental risks. By observing closely, in three very different situations, the way in which information is gathered, processed, distributed and used, this book examines the countless reformulations, redefinitions and even reorientations to which all information is subjected. This multiple reformatting, at least according to the hypothesis put forward in this book, is an important element in ensuring that the information produced circulates and reaches those for whom it is intended. The intention is then to analyze the way in which information circulates in situations of risk and crisis. In order to do it, the authors propose a new theoretical model based on different approaches. This model is anchored in the trend of research that has been oriented towards a wider understanding of risks and their territorial and social consequences. These ideas question the approach to risk which focuses primarily on technical aspects and probability. The model also draws from approaches to risk that focus on the stakeholders involved in the debates and the need for an integrated vision of risks. Risks are thus considered heterogeneous, plural and transcalar. The information flow about risks was studied first in the SHOC Room of the World Health Organization (WHO) in Geneva, a central place through which passes all information destined to managing world-wide epidemic risks. Then the research team monitored the constitution and the reception of a field library about risks management and reduction sent to Madagascar, an island systematically hit by cyclones. This following process has permitted the analysis of information dissemination during a crisis situation. The third field work was done in Cameroun to observe the use and transmission of information in two NGO specializing in sanitary risks prevention using traditional and biomedical conceptualization of health and illness. The book ends with a practical tool to assess and help the information circulation in risk and crisis situations.

Background People with dementia often require full-time caregivers especially in the later stages of their condition. People with dementia and caregivers’ access to reliable information on dementia is essential as it may have an important impact on patient care and quality of life. This study aims to provide an overview of the information needs and information seeking behaviour of people with dementia and their non-professional caregivers. Methods We conducted a scoping review of the literature and searched four electronic databases for eligible studies published up to August 2018. Two reviewers independently screened studies and extracted data. Information needs were classified according to emerging themes in the literature, and information seeking behaviour was categorized using Wilson’s model of information behaviour. Results Twenty studies with a total of 4140 participants, were included in this review. Reported information needs focused on: (i) disease; (ii) patient care provision; (iii) healthcare services; and (iv) caregiver self-care. The most commonly reported information need was on healthcare service-related information. Characteristics found to influence information needs were the severity of dementia as well as patient and caregiver status. People with dementia and non-professional caregivers mainly displayed active searching, information seeking behaviour and preferred using electronic sources to obtain health information. Conclusion Current dementia information sources available in English are extensive in the information they offer, but more emphasis needs to be placed on healthcare service-related information. All studies originated from high income countries and focused on information needs of non-professional caregivers only. The only variables found to be associated to information needs were severity of dementia condition as well as patient/caregiver status. The information needs identified in this review can be used to inform development and design of future dementia resources for people with dementia and their non-professional caregivers.

Online health information seeking is undergoing a major shift with the advent of artificial intelligence (AI)-powered technologies such as voice assistants and large language models (LLMs). While existing health information-seeking behavior models have long explained how people find and evaluate health information, less is known about how users engage with these newer tools, particularly tools that provide \"one\" answer rather than the resources to investigate a number of different sources. This study aimed to explore how people use and perceive AI- and voice-assisted technologies when searching for health information and to evaluate whether these tools are reshaping traditional patterns of health information seeking and credibility assessment. We conducted in-depth qualitative research with 27 participants (ages 19-80 years) using a think-aloud protocol. Participants searched for health information across 3 platforms-Google, ChatGPT, and Alexa-while verbalizing their thought processes. Prompts included both a standardized hypothetical scenario and a personally relevant health query. Sessions were transcribed and analyzed using reflexive thematic analysis to identify patterns in search behavior, perceptions of trust and utility, and differences across platforms and user demographics. Participants integrated AI tools into their broader search routines rather than using them in isolation. ChatGPT was valued for its clarity, speed, and ability to generate keywords or summarize complex topics, even by users skeptical of its accuracy. Trust and utility did not always align; participants often used ChatGPT despite concerns about sourcing and bias. Google's AI Overviews were met with caution-participants frequently skipped them to review traditional search results. Alexa was viewed as convenient but limited, particularly for in-depth health queries. Platform choice was influenced by the seriousness of the health issue, context of use, and prior experience. One-third of participants were multilingual, and they identified challenges with voice recognition, cultural relevance, and data provenance. Overall, users exhibited sophisticated \"mix-and-match\" behaviors, drawing on multiple tools depending on context, urgency, and familiarity. The findings suggest the need for additional research into the ways in which search behavior in the era of AI- and voice-assisted technologies is becoming more dynamic and context-driven. While the sample size is small, participants in this study selectively engaged with AI- and voice-assisted tools based on perceived usefulness, not just trustworthiness, challenging assumptions that credibility is the primary driver of technology adoption. Findings highlight the need for digital health literacy efforts that help users evaluate both the capabilities and limitations of emerging tools. Given the rapid evolution of search technologies, longitudinal studies and real-time observation methods are essential for understanding how AI continues to reshape health information seeking.

Background Health Information-Seeking Behaviour (HISB) is necessary for self-management and medical decision-making among patients with inflammatory bowel disease (IBD). With the advancement of information technology, health information needs and seeking are reshaped among patients with IBD. This scoping review aims to gain a comprehensive understanding of HISB of people with IBD in the digital age. Methods This scoping review adhered to Arksey and O'Malley's framework and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews frameworks (PRISMA-ScR). A comprehensive literature search was conducted in PubMed, Embase, Web of Science, PsycINFO, CINAHL, and three Chinese databases from January 1, 2010 to April 10, 2023. Employing both deductive and inductive content analysis, we scrutinized studies using Wilson's model. Results In total, 56 articles were selected. Within the information dimension of HISB among patients with IBD, treatment-related information, particularly medication-related information, was identified as the most critical information need. Other information requirements included basic IBD-related information, daily life and self-management, sexual and reproductive health, and other needs. In the sources dimension, of the eight common sources of information, the internet was the most frequently mentioned source of information, while face-to-face communication with healthcare professionals was the preferred source. Associated factors were categorized into six categories: demographic characteristics, psychological aspects, role-related or interpersonal traits, environmental aspects, source-related characteristics, and disease-related factors. Moreover, the results showed five types of HISB among people with IBD, including active searching, ongoing searching, passive attention, passive searching, and avoid seeking. Notably, active searching, especially social information seeking, appeared to be the predominant common type of HISB among people with IBD in the digital era. Conclusion Information needs and sources for patients with IBD exhibit variability, and their health information-seeking behaviour is influenced by a combination of diverse factors, including resource-related and individual factors. Future research should focus on the longitudinal changes in HISB among patients with IBD. Moreover, efforts should be made to develop information resources that are both convenient and provide credible information services, although the development of such resources requires further investigation and evaluation.

Curiosity—our desire to know—is a fundamental drive in human behaviour, but its mechanisms are poorly understood. A classical question concerns the curiosity motives. What drives individuals to become curious about some but not other sources of information? 1 Here we show that curiosity about probabilistic events depends on multiple aspects of the distribution of these events. Participants ( n  = 257) performed a task in which they could demand advance information about only one of two randomly selected monetary prizes that contributed to their income. Individuals differed markedly in the extent to which they requested information as a function of the ex ante uncertainty or ex ante value of an individual prize. This heterogeneity was not captured by theoretical models describing curiosity as a desire to learn about the total rewards of a situation 2 , 3 . Instead, it could be explained by an extended model that allowed for attribute-specific anticipatory utility—the savouring of individual components of the eventual reward—and postulates that this utility increased nonlinearly with the certainty of receiving the reward. Parameter values fitting individual choices were consistent for information about gains or losses, suggesting that attribute-specific anticipatory utility captures fundamental heterogeneity in the determinants of curiosity. Kobayashi et al. show that when options are defined by multiple attributes, people are curious about individual attributes regardless of the uncertainty of the total outcome, revealing a distinct type of anticipatory utility that shapes curiosity.

Background Health information seeking behavior (HISB) is a prevalent research topic. However, little is known about sociodemographic factors of HISB in China. This study aimed to examine the HISB of urban patients in China and identify predictors of source preference, online information seeking, and the timing of online seeking. Methods Based on the Health Information National Trends Survey (HINTS), this study conducted a cross-sectional survey of 1653 participants in different types of hospitals in 3 cities of different income levels within Zhejiang Province, China. Binary logistic regression analysis and multinomial logistic regression analysis were used to identify predictors of source preference, online medical information seeking, and the timing of online seeking for urban patients. Results The offline was the primary source of medical information for 58.61% of adult urban patients, while 78.19% had ever sought medical information online. 36.81% of online medical information seekers sought information before the medical visit, 8.65% sought information after the visit, and 54.54% sought information before and after the visit. China’s urban patients with higher education levels, higher income levels, young, active in internet use, and living in high-income cities were more likely to be active online medical information seekers (using the internet as the primary source) and online medical information seekers (having ever sought medical information online). Except for gender and age, most sociodemographic characteristics were not significantly associated with the timing of online medical information seeking. Conclusions Significant predictors of active online medical information seekers and online medical information seekers in China were almost the same. Regional economic development had a significant direct impact on medical information seekers. Most sociodemographic characteristics were not significantly associated with the timing of online medical information seeking. The findings of this study imply that China’s health information technology industry has Chinese characteristics.

In the absence of vaccines and specific drugs, prevention effort has been attributed as the primary control mechanism of COVID-19. Knowledge, attitude, and practice are used to determine the current situation and formulate appropriate control interventions as well as risk communication. This study, therefore, aims to assess knowledge, attitude, practice and information needs about COVID-19 in Indonesian society. A cross-sectional study was conducted through an online survey in the third week of August 2020. Purposive and random sampling was used to select the respondents. People with a minimum age of 18 years and residing in Indonesia were allowed to participate in this study. The survey was conducted with an online questionnaire that spread on several platforms such as WhatsApp, Instagram and Facebook by distributing the link and continuous chain messages on that platform. Data were analysed using descriptive, chi-square and logistic regression test. A total of 816 respondents were included in this study. In general, public knowledge about COVID-19 was sufficient, but some topic areas were still low. Most people had a positive attitude about the COVID-19, but they provided a negative response to government policies. Most of the community has taken preventive measures for COVID-19. However, some behaviours received a low percentage. Information about how to prevent COVID-19 was the most wanted information during this pandemic. Social media was a favourite source of information, with the most popular type of visualisation was a table containing numbers. Age and education were significantly associated with knowledge. Some attitudes were affected by age and occupation scope. Gender and health insurance ownership significantly associated with preventive measures. This research highlights the importance of providing valid, effective, efficient, and continuous information to the public through appropriate channels to increase understanding about COVID-19 precautions.

Background Although Internet has become the main way of access to health and medical information for most young people today, it might not be the case with older people. The elderly that have difficulty using the Internet rely largely on their family members to obtain and evaluate online health and medical information. Objective The purpose of this study is to investigate medical students’ proxy health information seeking behavior for their family members, and to look into how they search, evaluate, and even apply health information from the Internet. The paper is going to explore the influencing factors of health information seeking behavior of medical students as well as the concerns and difficulties they might encounter during the searching process. Methods Based on grounded theory, this study conducted semi-structured interviews with 30 medical students, from whom data were collected for analysis. Through the procedure of three-level coding, the theoretical framework of medical students’ proxy online health information seeking behavior was constructed. Results Findings of this study include the factors influencing medical student’ proxy online health information seeking, the emotional attitudes of the interviewees, and the results of proxy information seeking behavior. Students’ individual traits, information itself and the search platform all exercise influences on their seeking behavior. Interviewees mainly stay doubtful about the authenticity of health information and feel concerned over their parents’ physical conditions. Proxy seeking results are generally marked by positive feedback and negative feedback. Conclusions It satisfies the family members’ demand for health information that medical students seek online health information for them, and such behavior has a positive impact on the family members’ physical condition. Still, to evaluate the quality of health information from the Internet remains a major challenge that medical students face. Only through the joint efforts of both medical students and the related departments could high quality health information be obtained. Besides, for effective delivery of health information, medical students should also stay patient while communicating with their family members.

Background Exploration of health information-seeking behaviour among older adults with very low incomes is critical in shaping our understanding of how health information is sought in later life. Although studies have focused on health information-seeking behaviour among older people worldwide, subjective views of older adults, especially those with very low incomes in Ghana remain scant. Thus, this study aimed to fill this significant knowledge gap by exploring health information-seeking behaviour among older adults with very low incomes in Ghana. Methods In-depth interviews and focus group discussions were conducted with 30 older adults with very low incomes, 15 caregivers and 15 formal healthcare providers in the Atwima Nwabiagya District of Ghana. A thematic analytical framework was used to analyse the data. Results The study revealed multiple sources of health information to include healthcare providers, family members, media and friends. The kind of health information sought by older adults with very low incomes consisted of information on diets, causes of chronic non-communicable diseases and medication dosage. The study also identified inadequate knowledge about the benefits of seeking health information, perceived poor attitude of healthcare providers and communication problems as the factors that limit older adults with very low incomes from acquiring health information. Conclusion An adequate and reliable source of information is essential to promoting the health of older people. Their inability to secure the right health information could further worsen their health status . Thus, the study provides the need for appropriate health policy interventions on the sources and types of health information sought by older adults with very low incomes in Ghana. Healthcare providers are recommended to remain open, friendly and receptive to older people to allow them to seek and obtain health information as they [healthcare providers] constitute the most reliable health information source.
