Understanding the Relationship Between Direct Experience and Risk Perception of Natural Hazards

Dynamics of natural hazard risk awareness: Panel analysis insights from Switzerland

The analysis of risk awareness should be the initial stage in integrated natural hazard risk management to promote appropriate and effective measures for mitigating risks and strengthening social resilience inside the multi-risk framework. Nevertheless, earlier studies focused on cross-sectional data and overlooked the changes in risk awareness levels and associated independent variables with time. This study analyzes for the first time a balanced nationwide panel dataset of 1612 respondent-year observations from Switzerland (period 2015-2021, including the epidemic of COVID-19) to examine and compare the effects of potential independent variables on the four dimensions of natural hazard risk awareness (NHRA), ranging from the broadest dimension of Relevance to higher dimensions of Perceived Probability of an event, Perceived Threat to life and valuables, and Perceived Situational Threat. The analysis in this study incorporates multiple methods of Random-Effect Model (RE), Generalized Linear Model (GLM), and mediation analysis. Results show that NHRA increased in Switzerland to different extents (up to 23.24%) depending on the dimension. Event memory, perceived information impact and reported individual informed level appeared to be the most consistent independent variables positively influencing panel NHRA. Among these, perceived information impact as an important indicator of risk communication, was also found to serve as a mediator from risk preparedness to risk awareness. By encouraging residents to engage in "Begin Doing Before Thinking" (BDBT) programs to leverage subliminal effects and self-reflection, this study proposes that behavior-cognition feedback loops may facilitate a virtuous cycle. Our promising observations provide recommendations for an effective awareness-rising strategy design and suggest extensive insights from potential short-interval panel analysis in the future.

The influence of risk awareness and government trust on risk perception and preparedness for natural hazards

Risk perception is considered the primary motivator for taking preparedness actions. But people with prior experience and a high-risk perception are not necessarily more prepared. This relationship is even more complex when assessing preparedness levels for hazards with different characteristics. These inconsistent findings can be explained by how preparedness has been measured and the influence of other factors, such as trust and risk awareness. Thus, the main goal of this study was to analyze the role of risk awareness and trust in authorities on risk perception and intention to prepare for natural hazards in a coastal city in Chile. A representative sample of the city of Concepción, located in the center-south zone of Chile (n = 585), completed a survey. We measured risk awareness, risk perception, trust in authorities, and intention to prepare for two hazards: earthquakes/tsunamis and floods. Through structural equation models, we tested five hypotheses. We found that the perception of risk maintained a direct and positive influence on the intention to prepare for both hazards. The results showed that awareness and risk perception influence the intention to prepare and should be considered different concepts. Finally, trust did not significantly influence risk perception when faced with known hazards for the population. Implications for understanding the relationship between risk perception and direct experience are discussed.

How message appeals and prior product use influence information processing, risk perceptions, trust, attitudes, and genetic test purchase intentions

Within the direct-to-consumer (DTC) genetic test industry, attracting customers can be difficult especially due to the highly sensitive nature of these products. How these tests are communicated to consumers may be one avenue in which companies can impact customer purchase intentions. A 2 (message sidedness: one-way vs. two-way refutational) x 2 (hedging: present vs. absent) between-subjects experiment was conducted to understand how message features and prior product use influence information processing, risk and trust perceptions, and attitude toward the genetic test, which in turn, may influence direct-to-consumer (DTC) genetic test purchase intentions. Results demonstrated that having used a genetic test in the past predicted participants' trust in the company, information processing, and risk judgments; however, among those who used a genetic test, viewing a message that included hedging tended to increase their trust in the message. Trust in the message and company, information processing, and risk judgments significantly predicted participants' attitudes toward genetic testing, which in turn predicted their purchase intentions. The results suggest that in the context of DTC genetic test messaging, practitioners should strive to increase consumer trust in the message and the company and facilitate information processing, and they should work to diminish perceived risk. These results suggest opportunities for identifying other message features that may influence message and company trust, information processing, risk judgments, and attitudes related to DTC genetic testing.

Climate change and non-migration - exploring the role of place relations in rural and coastal Bangladesh

Of growing research and policy interest are the experiences of people living under conditions of climate change-induced environmental stress, which either are unable to migrate (sometimes described as a 'trapped population') or are seemingly unwilling to do so (sometimes described as the 'voluntarily immobile'). This paper problematises and expands upon these binary categories: examining the complex dimensionality of non-migration as a form of place relations, explored through qualitative study of rural and coastal Bangladeshi communities. Through 60 semi-structured interviews of individuals from four communities in the Kalapara region, the analysis proffers four qualitatively derived and inter-related dimensions of voluntary and involuntary non-migration framed as a form of place relations. These four dimensions concern the following: (1) livelihood opportunities, (2) place obduracy, (3) risk perceptions, and (4) social-structural constraints, with the interplay between these elements explaining diverse non-migratory experiences. In our analysis, 'place obduracy' is introduced as a concept to describe the differential speed of environmental change and socio-cultural adaptation responses to explain non-migratory experiences. Our discussion provides insight into how to best support non-migrant people's adaptive capacity in the face of growing climate emergency.

Public and Private Information Sharing under "New Normal" of COVID-19: Understanding the Roles of Habit and Outcome Expectation

Information sharing is critical in risk communication and management during the COVID-19 epidemic, and information sharing has been a part of individual prevention and particular lifestyles under the "New Normal" of COVID-19. Thus, the purpose of this study was to explore influencing factors and mechanisms in public and private information sharing intention among people under the regular risk situation. This study investigated an information sharing mechanism based on a cross-sectional design. We collected 780 valid responses through a sample database of an online questionnaire platform and utilized partial least squares structural equation modeling (PLS-SEM) to further analyze the data. To explore the difference caused by news frames, we divided respondents into two groups according to the news frame (action frame vs. reassurance frame) and proceeded with the multi-group analysis. The results showed that four types of outcome expectations (information seeking, emotion regulation, altruism and public engagement) and habit had impacts on public and private information sharing intention. Two paths influencing information sharing proposed in this study were supported. The results showed that outcome expectations were positively related to habit, which implies that the cognitive mechanism was positively relevant to the formation of habit. The results proved that habit played a mediating role between outcome expectations and information sharing. This research found that emotion regulation and public engagement outcome expectations only affected two types of information sharing intention mediated by habit. Regarding the role of the news frame, this study found no significant difference between the group exposed to action-framed news and the group exposed to reassurance-framed news. By exploring influencing factors and the mechanism of information sharing under the "New Normal", these findings contribute to understanding of information sharing and have implications on risk management. The proposed mechanism classifying public and private information sharing complements risk information flowing by considering online risk incubation.

Prioritization of Resilience Initiatives for Climate-Related Disasters in the Metropolitan City of Venice

Increases in the magnitude and frequency of climate and other disruptive factors are placing environmental, economic, and social stresses on coastal systems. This is further exacerbated by land use transformations, urbanization, over-tourism, sociopolitical tensions, technological innovations, among others. A scenario-informed multicriteria decision analysis (MCDA) was applied in the Metropolitan City of Venice integrating qualitative (i.e., local stakeholder preferences) and quantitative information (i.e., climate-change projections) with the aim of enhancing system resilience to multiple climate-related threats. As part of this analysis, different groups of local stakeholders (e.g., local authorities, civil protection agencies, SMEs, NGOs) were asked to identify critical functions that needs to be sustained. Various policy initiatives were considered to support these critical functions. The MCDA was used to rank the initiatives across several scenarios describing main climate threats (e.g., storm surges, floods, heatwaves, drought). We found that many climate change scenarios were considered to be disruptive to stakeholders and influence alternative ranking. The management alternatives acting on physical domain generally enhance resilience across just a few scenarios while cognitive and informative initiatives provided resilience enhancement across most scenarios considered. With uncertainty of multiple stressors along with projected climate variability, a portfolio of cognitive and physical initiatives is recommended to enhance resilience.

The Role of Personal Risk Experience-An Investigation of Health and Terrorism Risk Perception in Germany and Israel

The present study examined the relationship between risk experience and risk perceptions in relation to the target (risk to the self vs. others) and for two different types of risk: acute risks (i.e., terrorist attacks) and cumulative health risks (i.e., alcohol consumption, tobacco consumption, and unhealthy eating) in two countries (Israel and Germany). An online survey (N = 571) was conducted to assess participants' previous personal experience with acute and cumulative risks and their personal and general risk perceptions. The results showed that personal experience with terrorism was related to increased personal and general risk perceptions, while personal experience with cumulative health risks was related to increased personal but not general risk perceptions. It is argued that an increase in risk perception with more risk experience can be explained by the amount of available information about people's personal as well as other people's risk status. The findings emphasize that the experience-risk perception relationship depends on the target of the risk and the type of risk experience.

Heterogeneity of values for coastal flood risk management with nature-based solutions

The purpose of this study was to understand preferences for different coastal flood protection measures and the factors that influence such preferences, to inform management and policy. The Discrete Choice Experiment applied to Wales residents revealed that there is willingness-to-pay for coastal flood protection, especially through Nature-based Solutions (NbS) including expanding saltmarsh area and increasing saltmarsh with high vegetation. The preference for NbS provides evidence for including specific coastal area targets in financial schemes initially aimed at other benefits from natural habitats, such as habitat creation for biodiversity. This joint action will maximise the benefits from NbS and ensure integrated and concerted efforts across, often disjointed, sectors. There were also high levels of heterogeneity for preferences in different groups of people. For instance, results support that direct flood experience and damage severity can give rise to behavioural intentions that support mitigation and adaptation measures. Findings also highlight how crucial environmental education and direct contact with the object of study are for securing support and buy-in for flood protection measures. This work is original in that it considers the different types of management for a habitat as NbS and the heterogeneity of preferences within a population. Results are significant in providing a basis for future NbS developments and in supporting flood risk policy and management.

The Effect of Experience on Anxiety in Food Safety Incidents—An Empirical Study on Infant Formula Safety Incidents in China

Infant formula incidents have endangered the dietary safety and healthy growth of infants and young children and are triggers of the public’s negative emotions, attracting widespread public attention. The aim of this research was to explore how perceived knowledge gap, risk perception, past actual risk experience, and media risk experience affect anxiety. The research data obtained from 506 respondents were divided into groups with actual risk experience and without actual risk experience. Then, PLS-SEM was used to analyze the data. The results show that risk perception mediated the relationship between perceived knowledge gap and anxiety. Specifically, for the group with actual risk experience, perceived knowledge gap had a significant direct impact on anxiety; however, there was no moderation effect of media experience on the relationship between perceived knowledge gap and risk perception. For the group without actual risk experience, perceived knowledge gap had no direct effect on anxiety, and media experience had a significant moderating effect on the relationship between perceived knowledge gap and risk perception. The results suggest that in infant formula safety incidents, actual risk experience and media risk experience have different influence mechanisms on anxiety. Actual risk experience will directly and intuitively bridge the relationship between perceived knowledge gap and anxiety. Meanwhile, groups without actual risk experience tend to be influenced by rational risk judgment, and this process is moderated by media risk experience.

Gender Differences on Psychosocial Factors Affecting COVID-19 Preventive Behaviors

Previous studies have reported differences between men and women in the adoption of preventive behaviors against infectious diseases. This study aims to examine gender differences on a set of psychosocial factors shown to influence preventive behaviors against infectious diseases such as COVID-19. We conducted a web survey (N = 1.004) a few weeks after the end of the peak of the first wave of infections in Chile. The survey assessed participants’ perception of risk and worry about the COVID-19 pandemic, confidence in the government’s competence and integrity in dealing with the crisis, attribution of responsibility to various stakeholders, and adoption of preventive behaviors such as hygiene, distancing, and information-seeking. Our results confirm significant gender-based differences for both the psychosocial factors and the adoption of preventive behaviors. We conclude that women show a higher level of worry and fear of the pandemic and are keener to adopt preventive hygiene and social distancing behaviors. Similarly, participants report a low level of trust in government authorities, with women reporting the lowest trust level. The implications of these findings for the design of future risk communication strategies are discussed.
