A Cognitive-Affective Scale for Hurricane Risk Perception

Disposal practices, risk perceptions, and quantification of potential active pharmaceutical ingredients (APIs) from used human medicine in Upper Citarum River Basin

This paper highlights potential active pharmaceutical ingredients (APIs) generations from improper disposal of medicines and captures the perceptions of key stakeholders - households and pharmaceutical actors in Upper Citarum River Basin (UCRB). Most pharmaceutical waste is disposed of with household waste, suggesting landfills are the most significant APIs contamination sources. We highlight the complex relationship between knowledge, risk perception, and behavioural intentions, stressing the relevance of risk perception as a mediator when studying how knowledge affects behaviour. Age and income are suggested to moderate risk perception and behavioural intention. There is a heavy use of over-the-counter and prescription drugs in UCRB, especially Paracetamol (426.1 tons/year) and Amoxicillin (343.7 tons/year). Measured herbal APIs highlight the cultural significance and dependence on traditional medicine. We suggest examining the influence of affect on perception and behaviour in safe medicine disposal and the environmental and health risk impact of APIs in the water systems.

The influence of partisan news on climate mitigation support: An investigation into the mediating role of perceived risk and efficacy

Perceptions of efficacy play a central role in motivating people to engage in climate actions. However, there has been little investigation into how different climate efficacy beliefs are formed and how they may be associated with support for climate mitigation policies. This study, based on the motivated control framework, examines how risk perceptions may differentially be associated with four types of efficacy constructs (self-efficacy, personal outcome expectancy, collective efficacy, and collective outcome efficacy). It also places the motivated control framework in the context of the partisan information sphere and examines how exposure to partisan news may influence mitigation policy support through the mediators of risk perceptions and the efficacy constructs. Results suggest that liberal- and conservative-leaning news exposure, respectively, associate with higher and lower supports for policies. Overall, risk perception was a significant mediator, and the mediating function of efficacy varied depending on the specific construct being examined. For liberal news use, increased risk perceptions had a positive association with policy support through self-efficacy and collective outcome expectancy but also had an unexpected negative association with policy support through personal outcome expectancy and collective efficacy. For conservative news use, decreased risk perceptions resulted in further decreased beliefs of self-efficacy and collective outcome expectancy, resulting in lower levels of support for climate policies. We also find that political ideology is a significant moderator for the mediation model. Implications for climate change communication are discussed.

Post-earthquake dizziness and its psychiatric comorbidities among adolescents following the 2023 Kahramanmaraş earthquakes in Turkey

OBJECTIVE

Natural disasters, such as earthquakes, have detrimental effects on mental health. The occurrence of dizziness following earthquakes, termed post-earthquake dizziness syndrome (PEDS), has been noted in the epicenter and surrounding areas. The current study aimed to explore the prevalence of PEDS and its association with psychiatric disorders among adolescents.

METHODS

The sample consisted of 100 adolescents, aged 10-17 years, who had no history of vertigo or dizziness and were treated at a child and adolescent psychiatry outpatient clinic.

RESULTS

In the aftermath of the earthquake, 68.0% of the adolescents reported experiencing PEDS. A higher prevalence of PEDS was found among female adolescents compared to males. The most frequently reported symptom of PEDS was a sensation of ground shaking, typically experienced indoors within a week following the earthquake. Unpaired t-test analysis revealed that adolescents with PEDS had significantly higher scores on scales measuring panic disorder, generalized anxiety disorder, and post-traumatic stress disorder compared to those without PEDS.

CONCLUSIONS

In summary, the findings highlight the potential association between PEDS and psychiatric disorders in adolescents. However, the underlying mechanisms remain elusive, necessitating further research to elucidate the connections between PEDS and psychiatric conditions for more effective treatment strategies.

A longitudinal investigation of risk perceptions and adaptation behavior in the US Gulf Coast

Climate change is occurring more rapidly than expected, requiring that people quickly and continually adapt to reduce human suffering. The reality is that climate change-related threats are unpredictable; thus, adaptive behavior must be continually performed even when threat saliency decreases (e.g. time has passed since climate-hazard exposure). Climate change-related threats are also intensifying; thus, new or more adaptive behaviors must be performed over time. Given the need to sustain climate change-related adaptation even when threat saliency decreases, it becomes essential to better understand how the relationship between risk perceptions and adaptation co-evolve over time. In this study, we present results from a probability-based representative sample of 2,774 Texas and Florida residents prospectively surveyed 5 times (2017-2022) in the presence and absence of exposure to tropical cyclones, a climate change-related threat. Distinct trajectories of personal risk perceptions emerged, with higher and more variable risk perceptions among the less educated and those living in Florida. Importantly, as tropical cyclone adaptation behaviors increased, personal risk perceptions decreased over time, particularly in the absence of storms, while future tropical cyclone risk perceptions remained constant. In sum, adapting occurs in response to current risk but may inhibit future action despite increasing future tropical cyclone risks. Our results suggest that programs and policies encouraging proactive adaptation investment may be warranted.

The relationship between earthquake risk perceptions, religious orientation, spiritual well-being in individuals with and without earthquake experience: a cross-sectional study

The physical and psychological effects of earthquakes on individuals with their experience dimension are important. This study aimed to examine the relationship between earthquake risk perception, religious orientation, and spiritual well-being among individuals with and without earthquake experience. The data collection instruments included a socio-demographic information questionnaire, earthquake risk perception scale, religious orientation scale, and three-factor spiritual well-being scale. Statistical evaluations were performed using independent samples t test, one-way ANOVA test, Mann-Whitney U test, Kruskal-Wallis test (Levene), Pearson correlation, and multiple linear regression analyses. About 59.9% of the participants had experienced an earthquake. Individuals with earthquake experience scored 33.04 ± 7.80 on the earthquake risk perception scale, 100.65 ± 20.80 on the religious orientation scale, and 119.66 ± 18.87 on the three-factor spiritual well-being scale. Those without earthquake experience scored 31.57 ± 7.74, 96.70 ± 18.46, and 114.09 ± 18.04 on the respective scales. The average scores on the earthquake risk perception scale were found to be statistically significant with respect to gender, while the average scores on the religious orientation scale and the three-factor spiritual well-being scale were found to be statistically significant with respect to both gender and substance use. The regression analysis revealed that religious orientation and three-factor spiritual well-being significantly predicted 13.5% of the variance in earthquake risk perception. Studies to increase individuals' risk perception are important in minimizing the destructive effects of earthquakes in countries in the earthquake zone.

Evacuate or social distance? Modeling the influence of threat perceptions on hurricane evacuation in a dual-threat environment

This study investigates how different risk predictors influenced households' evacuation decisions during a dual-threat event (Hurricane Laura and COVID-19 pandemic). The Protective Action Decision Model (PADM) literature indicates that perceived threat variables are the most influential variables that drive evacuation decisions. This study applies the PADM to investigate a dual-threat disaster that has conflicting protective action recommendations. Given the novelty, scale, span, impact, and messaging around COVID-19, it is crucial to see how hurricanes along the Gulf Coast-a hazard addressed seasonally by residents with mostly consistent protective action messaging-produce different reactions in residents in this pandemic context. Household survey data were collected during early 2021 using a disproportionate stratified sampling procedure to include households located in mandatory and voluntary evacuation areas across the coastal counties in Texas and parishes in Louisiana that were affected by Hurricane Laura. Structural equation modeling was used to identify the relationships between perceived threats and evacuation decisions. The findings suggest affective risk perceptions strongly affected cognitive risk perceptions (CRPs). Notably, hurricane and COVID-19 CRPs are significant predictors of hurricane evacuation decisions in different ways. Hurricane CRPs encourage evacuation, but COVID-19 CRPs hinder evacuation decisions.

Influence of social and psychological factors on smartphone usage during the COVID-19 pandemic

Objective

This study investigates the influence of psychological factors-specifically affective and cognitive risk perceptions, social distancing attitudes, subjective norms, and cabin fever syndrome-on smartphone usage intensity during the COVID-19 pandemic, with a particular focus on university students.

Methods

Utilizing a cross-sectional survey design, data were collected from 314 university students from South Korea and Vietnam. Structural equation modeling was employed to analyze the relationships between the psychological constructs and their impact on smartphone usage.

Results

The analysis confirms that both affective and cognitive risk perceptions significantly influence attitudes towards social distancing. Furthermore, these social distancing attitudes are found to significantly affect cabin fever syndrome, suggesting that positive attitudes towards social distancing are closely associated with higher reports of cabin fever. Notably, cabin fever syndrome emerges as a significant predictor of increased smartphone usage, underscoring its role as a mediator between prolonged isolation and digital engagement. Additionally, subjective norms are also shown to significantly influence smartphone usage intensity, highlighting the impact of social expectations on digital behaviors during the pandemic.

Conclusion

The study highlights the complex interplay between psychological distress induced by social restrictions and increased reliance on digital technology for social connectivity. These insights suggest that mental health interventions and digital literacy programs tailored to university students' needs can be effective in managing the negative impacts of prolonged social isolation.

Official sources, news outlets, or search engines? Rumour validation on social media during Hurricanes Harvey and Irma

This study, based on data collected from a representative sample of adults in the United States, explores the social cognitive variables that motivated Americans to validate rumours on social media about Hurricanes Harvey and Irma, both of which struck in August/September 2017. The results indicate that risk perception and negative emotions are positively related to systematic processing of relevant risk information, and that systematic processing is significantly related to rumour validation through search engines such as Google. In contrast, trust in information about the hurricane is significantly related to validation through official sources, such as FEMA (Federal Emergency Management Agency), and major news outlets such as The New York Times. Trust in information is also significantly related to systematic processing of risk information. The findings of this study suggest that ordinary citizens may be motivated to validate rumours on social media, which is an increasingly important issue in contemporary societies.

Impacts of social isolation and risk perception on social networking intensity among university students during covid-19

This paper aims to examine the impacts of social isolation and risk perception on social networking intensity during COVID-19. Data was gathered from 345 university students. The present study empirically analyzed the data through a partial least squares methodology. The analysis showed that perceived behavioral control positively impacts social networking intensity. Affective risk perception positively affects subjective norms and perceived behavioral control. Cognitive risk perception has a significant association with both subjective norms and perceived behavioral control. Moreover, cabin fever syndrome serves as the key determinant of both sub-scales of risk perception. This study is novel in that it organically examines the effects of risk perception, social action, and closure on social networking. The current research and findings will offer useful implications for service providers in the social network industry.

Improper weapons are a neglected category of harmful objects

According to legislation, objects are typically classified as weapons if they are offensive per se (referred to here as proper) and if they are adapted for use as weapons or carried with the intent of causing injury (referred to here as improper), with specific regulations on their usage and possession in public spaces. However, little evidence exists on the validity of this distinction in psychology, despite a widespread recognition of the importance of psychological states and subjective perceptions in risk assessment. We conducted an online survey to evaluate hazard perceptions in relation to three dimensions (dangerousness, frequency of events, controllability) of three object categories: proper weapons, improper weapons, and everyday objects. The data from our 300 respondents reveal that the three categories of objects differ from one another on the three dimensions. Moreover, hazard perceptions differ between males and females for improper weapons but less so for proper weapons. These findings suggest that proper and improper weapons are two psychologically distinct categories, albeit with fuzzy boundaries. Investigations into their differential properties may thus help improve risk assessment in security contexts.

Effects of Psychological Discomfort on Social Networking Site (SNS) Usage Intensity During COVID-19

To cope with the COVID-19 pandemic, many countries are implementing social measures. Social distancing, working from home, and non-face-to-face lectures have led to major changes in people's activities. Since face-to-face classes are restricted, students in higher education become to feel psychological and cognitive discomforts such as isolation and risk perception. The purpose of this study is to explore the effects of psychological discomforts on the social network site (SNS) usage intensity of University students. Using structural equation modeling (SEM), this study applied SmartPLS 3.3.9 to analyze 271 valid samples. The results show that the affective risk perception significantly affects social distancing attitude. Cognitive risk perception is positively related to social distancing intention. In addition, cabin fever syndrome influences SNS usage intensity, affective risk perception, and cognitive risk perception. In conclusion, psychological discomfort partially affects the intensity of SNS use. Therefore, the government should set policies by reflecting citizens' mental difficulties and SNS activities together. Moreover, companies are needed to carefully consider the risk of the sense of isolation when marketing to SNS users.

Institutional trauma across the Americas: Covid-19 as slow crisis

Building on theories of cultural trauma, this research examines institutional trauma engendered by the pandemic in relation to journalism and public health in the US and Brazil. The trauma stemming from Covid-19 marks a transformational crisis not only in terms of global public health but also collective confidence in institutions writ large. To probe these issues, this article takes advantage of a vibrant digital discussion among Americans and Brazilians hosted by three flagship newspapers in the two countries: The New York Times, Folha de S. Paulo, and O Estado de S. Paulo. The analysis reveals that both groups experience Covid-accelerated trauma that undermines Brazilians’ and Americans’ faith in foundational institutions’ ability to adequately respond to the pandemic. Comparing these interpretations of the Covid-19 crisis in the US and Brazil allows us to see how the acute health crisis triggered by the virus morphs into a form of institutional trauma, with deep implications for collective confidence in public health, journalism, and democracy.

Rethinking Risk Perception and its Importance for Explaining Natural Hazard Preparedness Behavior

Psychological theory suggests there is a positive association between risk perception and protective behavior. Empirical research has, however, found mixed support for the positive link between risk perception and protective behavior. One explanation for the inconsistent link is the way in which risk perception has been conceptualized and/or operationalized in past research. Specifically, few studies acknowledge differences in hazard severity and how it might affect risk perception and protective behavior. Past research has also tended to overlook the importance of emotional appraisal in relation to perceived hazard consequences. To address these inconsistencies in past research, 337 people living in a cyclone-prone location were recruited to participate in an online study. In this study, respondents were randomly presented with one of five hypothetical cyclone scenarios, which differed in objective severity. Respondents were also presented with a survey, which assessed risk perception, protective action perceptions (or coping appraisal), and intentions to perform short-term protective behaviors. As hypothesized, risk perception significantly increased preparedness intentions when controlling for hazard severity, hazard probability, and protective action perceptions. Moreover, the degree to which respondents associated negative emotions with predicted damage was also a relatively strong predictor of preparedness intentions. Overall, the findings support the theoretical link between risk perception and protective behavior and provide a new method of assessing risk perception in cross-sectional research. On a practical level, the results suggest that increasing risk perception should promote protective behavior in response to natural hazards.

The closer I am, the safer I feel: The "distance proximity effect" of COVID-19 pandemic on individuals' risk assessment and irrational consumption

The unprecedented crisis of COVID-19 posed severe negative consequences for consumers, marketers, and society at large. By investigating the effect of individuals' distance from the COVID-19 epicenter (i.e., the geographical area in which COVID-19 pandemic is currently most severe) on consumers' risk perception and subsequent behaviors, this research provides novel empirical findings that can offer practical insights for marketers. While intuitively, people expect individuals closer to the COVID-19 epicenter to generate a greater risk perception of the pandemic, empirical evidence from four studies provides consistent results for the opposite effect. We find that a closer (vs. farther) distance to the epicenter associates with lower (vs. higher) perceived risk of the pandemic, leading to less (vs. more) irrational consumption behaviors. We refer to this phenomenon as the "distance proximity effect," which holds for both physical and psychological distances. We further demonstrated that this effect is mediated by consumers' perception of uncertainty and moderated by individuals' risk aversion tendency. The current research contributes to the literature of consumers' risk perception and irrational consumption by highlighting a novel factor of distance proximity. It also offers some timely insights into managing and intervening COVID-19 related issues inside and outside an epicenter.

The perceived risk of being infected at work: An application of the job demands-resources model to workplace safety during the COVID-19 outbreak

Safety at work, both physical and psychological, plays a central role for workers and organizations during the ongoing outbreak of COVID-19. Building on the job demands-resources (JD-R) model applied to safety at work, in this study we proposed that the perceived risk of being infected with COVID-19 at work can be conceptualized as a job demand (i.e., a risk factor for work-related stress), whereas those characteristics of the job (physical and psychosocial) that help workers to reduce or manage this risk can be conceived as job resources (i.e., protective factors). We hypothesized that the perceived risk of being infected at work is positively associated with emotional exhaustion. Furthermore, we hypothesized that job resources, in terms of safety systems, communication, decision-making, situational awareness, fatigue management, and participation in decision-making, are negatively associated with emotional exhaustion. We also hypothesized that job resources buffer the association between perceived risk and emotional exhaustion. Overall, 358 workers (meanage = 36.3±12.2 years) completed a self-report questionnaire, and the hypothesized relationships were tested using moderated multiple regression. Results largely supported our predictions. The perceived risk of being infected at work was positively associated with emotional exhaustion, whereas all the job resources were negatively associated with it. Furthermore, safety systems, communication, decision-making, and participation in decision-making buffered the relationship between the perceived risk of being infected at work and emotional exhaustion. In a perspective of prevention and health promotion, this study suggested that organizations should reduce the potential risk of being infected at work, whenever possible. At same time, those characteristics of the job that can help workers to reduce or manage the risk of infection should be strengthened.

The effects of natural disasters on international tourism: A global analysis

Tourism is shaped by a wide range of factors and forces, including exogenous ones that have no direct link with the tourism sector. Natural disasters and unexpected events are prime examples of such determining factors, as they have profound effects on individuals and society, and as a result have the potential to affect tourism flows considerably. Several theoretical arguments exist why natural disasters and unexpected events could influence tourist destination choices. However, empirical research to confirm the nature and extent of impacts of disasters on tourism is lacking. To address this gap, this paper incorporates a dataset on natural and man-made disaster events into a model of international tourism flows to evaluate the effect of different types of disasters on international arrivals at the national level. Findings provide evidence that the occurrence of different types of event change tourist flows to varying degrees. Although in some cases a positive effect is estimated, in general the impacts are negative, resulting in reduced tourist arrivals following an event. Understanding the relationship between disaster events and tourism is helpful for destination managers who make critical decisions in relation to recovery, reconstruction and marketing.

Communication and Hazard Perception Lessons from Category Five Hurricane Michael

Hurricane Michael made landfall on 10 October 2018 as only the third Saffir Simpson Hurricane Wind Scale (SSHWS) category 5 storm in the USA in the named era. The storm’s intensity, rapid intensification, October landfall, high inland winds, and uncommon landfall location all combined to complicate the communication and preparation efforts of emergency managers (EMs) and broadcast meteorologists (BMs), while clouding the comprehension of the public. Interviews were conducted with EMs, BMs, and a small public sample to hear their stories and identify and understand common themes and experiences. This information and previous research was used to inform the creation of questions for a large sample public survey. Results showed that 61% of our sample did not evacuate, and approximately 80% either underestimated the intensity, misinterpreted or did not believe the forecast, or realized the danger too late to evacuate. Hazard perception from a survey of the public revealed that wind followed by tornadoes, and falling trees were the major concerns across the region. According to their counties of residence, participants were divided into Coastal or Inland, and Heavily Impacted or Less Impacted categories. Inland participants expressed a significantly higher concern for wind, tornadoes, falling trees, and rainfall/inland flooding than Coastal participants. Participants from Heavily Impacted counties showed greater concern for storm surge, tornadoes, and falling trees than participants from Less Impacted counties. These results reinforce the continued need for all parties of the weather enterprise to strengthen communication capabilities with EMs and the public for extreme events.

Individual factors influencing risk perceptions of hazardous chemicals in China

In view of the public concern about the possible risks posed by hazardous chemicals in China, the study on risk perceptions offer an important opportunity to assess the public's awareness of the risks of hazardous chemicals as well as to predict the public behaviors. More specifically, this paper discusses the individual factors that affect risk perceptions and protective actions with 1700 questionnaires six cities of China. It was found upon statistical analysis that only gender has a significant impact on risk perceptions of all demographic indicators; what is more, men have a higher level of risk perceptions than women. Upon further analysis, four factors are identified and analyzed which are thought to affect risk perceptions and protective actions. Furthermore, the logical relationships among various elements were analyzed with SEM model. Results: first, one psychological factor (responsibility) and two ability factors (knowledge, skills) can make positive effects on risk perceptions; second, one psychological factor (trust) exerts a negative effect on risk perceptions; third, while psychological factors do make positive effects on protective actions, no significant correlation is found between the ability factors and protective actions. Then it can be deduced that it is beneficial to build a trusting relationship between the public and the government as well as to strengthen the public's sense of responsibility.

The Influence of Social Capital on Protective Action Perceptions Towards Hazardous Chemicals

The stigmatized character of hazardous chemicals has caused individuals in hazards to take excessive protective actions. Here, social capital is introduced to discuss its influence on the protective action decision model (PADM), considering this variable has a relatively high individual trust level in regards to information on hazardous chemicals. A model was constructed by taking protective action perceptions as the dependent variable, social capital as the independent variable, the pre-decision process as the mediating variable, and socioeconomic status as the moderating variables. Data were collected with a neighborhood sampling method, and a total of 457 questionnaires were obtained from neighboring residents near a large cold ammonia storage house in Haidian District, Beijing. Results: While the family and friendship networks produced a larger positive influence, the kinship network produced a smaller positive influence; furthermore, the influence of social capital must be brought through the pre-decision process; finally, socioeconomic status has a directional moderation on the friendship network, an enhancing moderation on the kinship network, and a weakening moderation on the family network.

Concerns and future preparedness plans of a vulnerable population in New Jersey following Hurricane Sandy

Knowing how people prepare for disasters is essential to developing resiliency strategies. This study examined recalled concerns, evacuation experiences, and the future preparedness plans of a vulnerable population in New Jersey, United States, following Hurricane Sandy in 2012. Understanding the responses of minority communities is key to protecting them during forthcoming disasters. Overall, 35 per cent of respondents were not going to prepare for an event. Intended future preparedness actions were unrelated to respondents' ratings of personal impact. More Blacks and Hispanics planned on preparing than Whites (68 versus 55 per cent), and more Hispanics planned on evacuating than did others who were interviewed. A higher percentage of respondents who had trouble getting to health centres were going to prepare than others. Respondents' concerns were connected to safety and survival, protecting family and friends, and having enough food and medicine, whereas future actions included evacuating earlier and buying sufficient supplies to shelter in place.

Developing a Broadly Applicable Measure of Risk Perception

Decades of research identify risk perception as a largely intuitive and affective construct, in contrast to the more deliberative assessments of probability and consequences that form the foundation of risk assessment. However, a review of the literature reveals that many of the risk perception measures employed in survey research with human subjects are either generic in nature, not capturing any particular affective, probabilistic, or consequential dimension of risk; or focused solely on judgments of probability. The goal of this research was to assess a multidimensional measure of risk perception across multiple hazards to identify a measure that will be broadly useful for assessing perceived risk moving forward. Our results support the idea of risk perception being multidimensional, but largely a function of individual affective reactions to the hazard. We also find that our measure of risk perception holds across multiple types of hazards, ranging from those that are behavioral in nature (e.g., health and safety behaviors), to those that are technological (e.g., pollution), or natural (e.g., extreme weather). We suggest that a general, unidimensional measure of risk may accurately capture one's perception of the severity of the consequences, and the discrete emotions that are felt in response to those potential consequences. However, such a measure is not likely to capture the perceived probability of experiencing the outcomes, nor will it be as useful at understanding one's motivation to take mitigation action.

Explicating Experience: Development of a Valid Scale of Past Hazard Experience for Tornadoes

People's past experiences with a hazard theoretically influence how they approach future risks. Yet, past hazard experience has been conceptualized and measured in wide-ranging, often simplistic, ways, resulting in mixed findings about its relationship with risk perception. This study develops a scale of past hazard experiences, in the context of tornadoes, that is content and construct valid. A conceptual definition was developed, a set of items were created to measure one's most memorable and multiple tornado experiences, and the measures were evaluated through two surveys of the public who reside in tornado-prone areas. Four dimensions emerged of people's most memorable experience, reflecting their awareness of the tornado risk that day, their personalization of the risk, the intrusive impacts on them personally, and impacts experienced vicariously through others. Two dimensions emerged of people's multiple experiences, reflecting common types of communication received and negative emotional responses. These six dimensions are novel in that they capture people's experience across the timeline of a hazard as well as intangible experiences that are both direct and indirect. The six tornado experience dimensions were correlated with tornado risk perceptions measured as cognitive-affective and as perceived probability of consequences. The varied experience-risk perception results suggest that it is important to understand the nuances of these concepts and their relationships. This study provides a foundation for future work to continue explicating past hazard experience, across different risk contexts, and for understanding its effect on risk assessment and responses.

Influence of Risk Perception on Attitudes and Norms Regarding Electronic Cigarettes

The use of electronic cigarettes has grown substantially over the last few years. Currently, about 4% of adults use electronic cigarettes, about 16% of high school students report use in the past 30 days, as do approximately 11-25% of college students. A hallmark of the reduction in tobacco use has been the shift in social norms concerning smoking in public. Such norms may also drive views on acceptability of public electronic cigarette use. While normative factors have been given attention, little substantive application of the literature on risk perception has been brought to bear. The overall aim of this study was to place a cognitive-affective measure of risk perception within a model that also includes social cues for e-cigarettes, addictiveness beliefs, and tobacco use to predict perceived social acceptability for public use of e-cigarettes. To do so, a cross-sectional study using an online survey was conducted among a sample of undergraduate students at a Western university (n = 395). A structural equation model showed that the acceptability of public e-cigarette use was influenced by social cues, beliefs about addiction, and cognitive risk perception, even after controlling for nicotine use. What is revealed is that cognitive assessment of e-cigarette risk and perception of addictiveness had a suppressing effect on perceived acceptability of public vaping, while greater exposure to social cues exerted a countervailing effect. This is evidence of the role that risk perception and social norms may play in the increases in electronic cigarette use that have been observed.

Sizing Up a Superstorm: Exploring the Role of Recalled Experience and Attribution of Responsibility in Judgments of Future Hurricane Risk

Research suggests that hurricane-related risk perception is a critical predictor of behavioral response, such as evacuation. Less is known, however, about the precursors of these subjective risk judgments, especially when time has elapsed from a focal event. Drawing broadly from the risk communication, social psychology, and natural hazards literature, and specifically from concepts adapted from the risk information seeking and processing model and the protective action decision model, we examine how individuals' distant recollections, including attribution of responsibility for the effects of a storm, attitude toward relevant information, and past hurricane experience, relate to risk judgment for a future, similar event. The present study reports on a survey involving U.S. residents in Connecticut, New Jersey, and New York (n = 619) impacted by Hurricane Sandy. While some results confirm past findings, such as that hurricane experience increases risk judgment, others suggest additional complexity, such as how various types of experience (e.g., having evacuated vs. having experienced losses) may heighten or attenuate individual-level judgments of responsibility. We suggest avenues for future research, as well as implications for federal agencies involved in severe weather/natural hazard forecasting and communication with public audiences.

RF EMF Risk Perception Revisited: Is the Focus on Concern Sufficient for Risk Perception Studies?

An implicit assumption of risk perception studies is that concerns expressed in questionnaires reflect concerns in everyday life. The aim of the present study is to check this assumption, i.e., the extrapolability of risk perceptions expressed in a survey, to risk perceptions in everyday life. To that end, risk perceptions were measured by a multidimensional approach. In addition to the traditional focus on measuring the magnitude of risk perceptions, the thematic relevance (how often people think about a risk issue) and the discursive relevance (how often people think about or discuss a risk issue) of risk perceptions were also collected. Taking into account this extended view of risk perception, an online survey was conducted in six European countries with 2454 respondents, referring to radio frequency electromagnetic field (RF EMF) risk potentials from base stations, and access points, such as WiFi routers and cell phones. The findings reveal that the present study’s multidimensional approach to measuring risk perception provides a more differentiated understanding of RF EMF risk perception. High levels of concerns expressed in questionnaires do not automatically imply that these concerns are thematically relevant in everyday life. We use thematic relevance to distinguish between enduringly concerned (high concern according to both questionnaire and thematic relevance) and not enduringly concerned participants (high concern according to questionnaire but no thematic relevance). Furthermore, we provide data for the empirical value of this distinction: Compared to other participants, enduringly concerned subjects consider radio frequency electromagnetic field exposure to a greater extent as a moral and affective issue. They also see themselves as highly exposed to radio frequency electromagnetic fields. However, despite these differences, subjects with high levels of thematic relevance are nevertheless sensitive to exposure reduction as a means for improving the acceptance of base stations in their neighborhood. This underlines the value of exposure reduction for the acceptance of radio frequency electromagnetic field communication technologies.
