Background: The coronavirus disease 2019 (COVID-19) pandemic continues to adversely impact the United States socially, culturally, and economically. The purpose of this study was to understand the relationship between COVID-19 county death rates, risk perception, and US adults' voluntary behaviors-particularly physical distancing., Methods: Data were collected from CloudResearch/Qualtrics, Johns Hopkins University, the American Community Survey, and SafeGraph., Results: Our results indicated that higher COVID-19 county death rates were associated with higher risk perceptions, leading to greater time spent at home., Conclusions: These findings will help public health officials identify strategies that best encourage voluntary health behaviors to help curb the spread of COVID-19., (© The Author(s) 2021.

We propose a Pandemic Risk Perception Scale. Our scale comprises two constructs, Dread Risk and Personal Exposure, divided into five dimensions: Infection Risk, Emotional Health Risk, Health System Risk,Financial Risk, and Alimentary Risk. Using multidimensional item response theory, confirmatory factor analysis, and structural equation modeling on two samples of respondents, our results show that Alimentary Risk, Health System Risk, and Emotional Health Risk are the main dimensions of risk perception for the COVID-19 pandemic. Furthermore, Infection Risk has a minor impact on the pandemic's risk perception, suggesting the presence of different dynamics between personal and general risk perceptions for the COVID-19 pandemic., (© 2021 Society for Risk Analysis.)

This article elicits information about risk perceptions and risk-risk tradeoffs for mass shootings and international terrorist attacks. These prominent public risks are similar in many respects in that both involve traumatic injuries. One might expect that the risk-risk tradeoff rate would be 1.0 unless other attributes of these risks are pertinent. Estimates based on an original survey structured to test rates of tradeoff between deaths from these risks indicate that respondents consistently place a premium on reducing mass shooting risks, as compared to risks of international terrorism. The average premium is relatively stable even after accounting for the effect of differences in personal risk beliefs on policy preferences. The estimated rates of risk-risk tradeoff reflect a greater weight on mass shooting risks even for those who believe that international terrorism risks pose a greater personal threat., (© 2021 Society for Risk Analysis.)

Use of nutrient management practices to reduce nutrient loss from agriculture and its associated water quality consequences, including hypoxia and eutrophication, is widely encouraged. However, little is known about which factors influence farmers' risk perceptions associated with nutrient loss, and thus possibly influence their decisions to adopt such practices. To determine which factors were associated with relative "accuracy" of nutrient loss-associated risk perceptions, specific farm field management information was used as inputs to a Soil and Water Assessment Tool model of the study watershed to produce water quality outputs for each modeled farm field. This information was paired with farmers' risk perceptions associated with nutrient loss on their farm to assess relative "accuracy" of each farmer's perceptions compared to the rest of the farmers in the study. We then investigated characteristics of the farm and farmer that are associated with comparative "overprediction" and "underprediction" of risk, and found that characteristics of the individual (conservation identity, prior conservation practice adoption, efficacy beliefs, and perceived seriousness of the consequences of nutrient loss) are more important in determining whether farmers are likely to "overpredict" or "underpredict" risk than is the objective (modeled) vulnerability of their land to nutrient loss., (© 2021.

Rationale: Many countries were and are still struggling with the COVID-19 emergency. Despite efforts to limit the viral transmission, the vaccine is the only solution to ending the pandemic. However, vaccine hesitancy could reduce coverage and hinder herd immunity., Objective: People's intention to get vaccinated can be shaped by several factors, including risk perception which, in turn, is influenced by affect. The present work aimed at investigating how risk perception and some factors associated with the decision to comply with vaccination modulated vaccine acceptance for COVID-19 as compared to seasonal influenza, and how these have varied during the lockdown phases., Method: The study followed the main phases of the emergency in Italy, investigating the intention to get vaccinated against flu and against SARS-CoV-2 (if a vaccine was available) before, during and after the first national lockdown, covering the period from the end of February to the end of June 2020. We investigated the effect of risk perception and other predictors on the decision of getting vaccinated., Results: Compared to the pre-lockdown phase, during the lockdown more people were willing to get vaccinated for COVID-19, regardless of their beliefs about vaccines, and as risk perception increased, so did the intention to accept the vaccine. The acceptance of the flu vaccine increased after the re-opening phase. In addition, the intention to get vaccinated against COVID-19 and against flu increased if there was previous flu vaccination behavior but decreased with increasing doubts about the vaccines in general., Conclusions: The observation of vaccination intentions across the three main phases of the emergency allows important considerations regarding psychological, affect, and demographic determinants useful to tailor public health communication to improve public response to future epidemics., (Copyright © 2021 Elsevier Ltd.

Preventive behavior developed by the population is essential in the face of the risk of coronavirus infection (COVID-19). However, preventive measures will depend on the risk perception acquired. In addition, lockdown can directly affect mental health, provoking distress. Distress could affect risk perception. This study's objective was to analyze whether experiencing distress had an influence on risk perception with respect to vulnerable groups. The sample consisted of 806 participants. The study was conducted during the first week of lockdown declared by the Spanish Government. The Brief Symptom Inventory BSI-18 and a risk perception questionnaire about vulnerable groups was administered. The study revealed the appearance of distress in 9.6% of the sample (85.7% women). Experiencing distress influenced risk perception. This study's main contribution is the link between experiencing distress and the risk perception with respect to vulnerable groups. Risk perception is relevant since it can influence how the population faces the pandemic. Transmission of accurate information could help to minimize the effect of certain cognitive biases that affect risk perception and foster preventive behavior.

On 11 March 2020 the SARS-CoV-2 virus was officially declared a pandemic and measures were set up in various countries to avoid its spread among the population. This paper aims to analyse the perception of risk of COVID-19 infection in the Spanish population. A cross-sectional, descriptive observational study was conducted with a total of 16,372 Spanish participants. An online survey was used to gather data for 5 consecutive days over the compulsory lockdown period which was established after the state of emergency was declared. There is an association between socio-demographic variables and risk perception, and a very strong relationship between this perception and contact and direct experience with the virus in a family, social or professional setting. We also found that compared to working from home, working outside the home increased the perception of risk of infection and the perception of worsening health. Understanding the public perception of the risk of COVID-19 infection is fundamental for establishing effective prevention measures.

Background: The coronavirus disease 2019 (COVID-19) is a worldwide pandemic that continues to spread and the situation continues to deteriorate globally. It is also a risk event for the public in affected areas. However, little is known about the relationship between "being involved/exposed in a risk event at the moment" and people's risk perception of that event., Methods: The mediation model and analysis of covariance method were performed on a Chinese sample (N = 351) during the outbreak of COVID-19 to test the underlying mechanism between risk event involvement and risk perception., Results: Risk event involvement was positively related not only to people's event-related risk perception but also their general risk perception (i.e. risk perception towards other events), and negative emotion mediated these relationships. In addition, the residents of Wuhan (vs. non-Wuhan) exhibited significantly higher event-related risk perception as well as general risk perception., Conclusions: The findings deepen our understanding of risk perception by suggesting that being involved in a risk event at the moment is also a nonnegligible variable positively related to risk perception through increased negative emotion. Finally, theoretical and managerial implications of the result are discussed., (© 2020 International Association of Applied Psychology.)

Background: The ongoing coronavirus disease 2019 (COVID-19) outbreak has elicited concerns about public fear and economic fallout. The current study takes a person-oriented approach to identify the unique response patterns that underlie three risk perception components (likelihood, severity, and protection efficacy) of COVID-19, with information sources as precursors and economic confidence as outcomes., Methods: A total of 1,074 Chinese citizens participated in a national online survey in early February 2020., Results: A latent profile analysis showed that participants exhibited one of three classes: Risk Neutrals (49.9%; moderate in all components), Risk Deniers (14.3%; low likelihood, low severity, and high protection efficacy), or Risk Exaggerators (35.8%; high likelihood, high severity, and low protection efficacy). Subsequent analyses showed that reliance on unofficial sources (gossip and news spread among friends; WeChat) positively correlated with membership in the Risk Exaggerators class. In turn, belonging in the Risk Exaggerators class correlated with the lowest short-term (but not long-term) economic confidence., Conclusions: This study suggests that exploring the heterogeneity of the public risk perception might help the government to design differentiated risk communication strategies during the COVID-19 outbreak., (© 2020 International Association of Applied Psychology.)

Background: Cognitive risk perception has been linked to health behavior needed to reduce the risk of developing type 2 diabetes. The concept of risk perception of developing diabetes needed review due to: (a) frequent lack of congruency between perceived and actual risk of developing diabetes, and (b) inconsistent measures for calculating perceived diabetes risk., Design: The concept analysis was conducted using the Walker and Avant approach., Data Sources: Dictionary definitions, thesaurus synonyms and antonyms, theoretical sources, and seminal works related generally to risk perception were reviewed. Database searches for studies conducted in the United States measuring perceived risk of developing diabetes, were conducted in PubMed, Embase, and CINAHL; resulting in the selection and review of 23 research articles., Results: The identified dimensions of perceived diabetes risk were: perceived likelihood, personal risk, general risk, cognitive, emotional, comparative risk, and unrealistic optimism. Some antecedents of perceived diabetes risk were motivational factor, individual difference, contextual factor, cognitive factor, and affective factor. A consequence of perceived diabetes risk was health-promoting behaviors., Conclusions: This concept analysis increases clarity of a multidimensional concept, providing a basis for validity for measurements. Consideration of antecedents for perceived diabetes risk will be important as related to diabetes prevention efforts., (© 2020 Wiley Periodicals LLC.)

Endocrine disrupting chemicals (EDCs) are exogenous chemicals found in food, consumer products, and the environment. EDCs are ubiquitous in modern life and exposure is associated with many negative health effects, such as reproductive disorders, metabolic disorders, and cancer. Scientists have deemed EDCs as a serious public health risk, yet the public's perceptions of these chemicals is poorly understood. This study aimed to qualitatively explore how aware the public is of EDCs and their attitudes, beliefs, and perceptions of EDC risk. Thirty-four participants (aged 19-65 years) took part in the six focus groups. Discussions were transcribed verbatim and Nvivo 11 was used for thematic analysis. Our results indicated that awareness of EDCs was low. Themes of EDC risk perception included perceived control, perceived severity, and similarity heuristics. Risk alleviation strategies were also discussed. Future research should use quantitative methodology and a larger sample size to validate the findings from this study. Findings from this study may aid the development of effective risk communication strategies and public health interventions.

Studying typhoon risk perception and its influencing factors help reveal potential risk factors from the perspective of the public and provide a basis for decision-making for reducing the risk of typhoon disasters. The purpose of this study is to assess the risk perception and related factors of Macao residents in China. Information was collected from 983 participants using a structured questionnaire with an effective utilization rate of 94.2%. Descriptive statistics, univariate analysis and correlation analysis were used to analyze the data. The results show that, on the one hand, there are significant differences in risk perception on the factors included: (1) age, education and other demographic characteristics; (2) health status, occupation, length of stay, residence area, residence floor, family organization structure and individuals monthly income and other personal or family conditions; (3) channels and quantity of typhoon information acquisition; (4) degree of mastery of relevant risk aversion knowledge. On the other hand, some factors still have a moderate or high level of correlation with risk perception: (1) The older the respondent, the lower the education level, the lower the income, the lower the risk perception of property damage, health impact and life threat. (2) The more children or elderly people in the family, the higher the risk perception of respondents. (3) The more risk knowledge, the lower the risk perception. (4) The more channels for obtaining information, the lower the fear level and the overall impact of risk perception. (5) The stronger the risk perception, the more positive disaster response behaviors would be taken by the public. In addition, the more information acquisition channels and the less risk knowledge respondents have, the greater the risk perception of the overall impact and the fear of the typhoon; the fewer information access channels and less risk knowledge respondents have, the greater the risk perceptions of property damage, health effects and life threats.

Flood is the most common natural hazard in Iran, which annually affects the environment and human lives. On March 25, 2019 in Shiraz-Iran, following a heavy rainfall, the occurrence of a flash flood caused an extensive number of deaths, injuries, and vehicle demolitions in a short time. Evidence suggests that man-made causes of the incident, including unsustainable urban development and lack of early warning services, have played a more influential role compared with its natural causes. This study has attempted to substantiate that understanding disaster risks, as the first priority of Sendai Framework for Disaster Risk Reduction (SFDRR) 2015-2030, directly impacts the decisions and actions of policymakers, local authorities, and the public. To provide more safety, mitigation, and disaster risk reduction, attention should primarily be paid on making a cultural paradigm shift through providing sufficient training in developing appropriate disaster risk perception in the community at large.

Background: An increasing number of international travellers are at risk for dengue infection. We analysed the characteristics of Finnish travellers with recently acquired dengue infections. Methods: Notified dengue infections from 2016 to 2019 were obtained from the Finnish National Infectious Disease Register. We developed a questionnaire and invited individuals diagnosed with dengue to provide information on countries and areas of infection, travel characteristics, risk perception and use of protective measures. Results: Almost all infections (94%, 127/135) were acquired in Asian countries, most in Thailand (78/135, 58%). The Maldives had the highest crude risk after adjusting for the number of travellers (55.6/100,000). Most trips were pre-booked holidays (93/111, 84%) and 62% (69/111) had a duration of 14-21 days with time spent mostly on the beach (78/111, 70%). The majority of travellers were not aware of the risk of dengue infection before travelling (67/111, 60%) and had not sought pre-travel advice (72/111, 65%). The majority applied some protective measures (71/111, 64%) but mainly after sunset (64/111, 58%). Conclusions: Most dengue infections in Finnish travellers were acquired at popular destinations in Southeast Asia, especially Thailand. Our study showed that there was low awareness regarding the risk of contracting the infection. In addition, many travellers reported inadequate use of protective measures. This calls for further public health actions, such as raising awareness of day-active mosquitoes, of risk at popular travelling destinations and the correct way of applying anti-vectorial measures.

There is wide use of antimicrobial products in rural poultry farms in most sub-Sahara African countries. However, little is known of the factors that motivate rural poultry farmers towards antimicrobial use (AMU) and their level of awareness about antimicrobial resistance (AMR). This cross sectional survey was conducted to investigate the knowledge, attitudes, practices, perception of poultry farmers in Cameroon about AMU and risk of AMR (KAPP) (n = 358). The data collection was conducted using questionnaires administered through face-to-face interview and the responses were recoded into binary scale. The sum of sufficient responses provided by each participant divided by the total number of items within the category gave a percentage of correct answers. One-way ANOVA was used to assess significant differences of mean KAPP scores across regions. Pearson correlations were used to calculate the association between KAPP scores across and within regions, while the linear regression was done to explore the relationship between demographics and farmer's dynamic characteristics. Overall, surveyed poultry farmers showed low mean score knowledge of AMU (0.30 ± 0.24) and AMR (0.26 ± 0.22), desirable attitude (0.29 ± 0.29), appropriate practice (0.58 ± 0.18) towards AMU and positive risk perception of AMR (0.37 ± 0.21). Digestive tract infections and chronic respiratory diseases were the most common reasons for antimicrobial use and for preventive purposes. Gender, experience in poultry farming and stocking density were negatively associated with practice of antimicrobial use. Inappropriate combination of antimicrobials with diuretics or tetracyclines and minerals for treatment purposes were frequently observed. The findings revealed strong positive association between educational level and KAPP score and between biosecurity measures and AMU and risk perception of AMR. Thus, continuous education of rural poultry farmers on husbandry norms, drug use and microbial resistance in animal farms will enhance their knowledge and risk perception on AMU as well as enable them adopt suitable attitude and practices to control animal and human health hazards due to AMR., (Copyright © 2020 Elsevier B.V.

On 19 March 2020, I last met with a group of women from a neighbourhood of Monterrey, Mexico where I have spent the past year conducting ethnographic research. They had scheduled a meeting to decide whether to continue our weekly talks on health-related topics. 'Is this coronavirus real?' was the question guiding the meeting. Women shared their thoughts on their feelings on the threat that predominates in biomedical discourse. An air of resignation pervaded their speech. Nearly all of them suffer from chronic diseases and they clearly perceive the risk of their own death. However, the material conditions of their lives limit the scope of their strategies to protect themselves. A dialogue emerged between the women's request for clarity regarding the pandemic and me, a researcher called on as a physician. This article seeks to reflect on the political and moral aspects of everyday life that configure risk perception in the context of the WHO-declared pandemic. I analyse the dialogue sustained in the meeting as part of an ethnographic research I am conducting in this neighbourhood. Most of its residents live under precarious circumstances, which is a fundamental element in understanding their responses to the current COVID-19 crisis.

Previous studies of risk behavior observed weak or inconsistent relationships between risk perception and risk-taking. One aspect that has often been neglected in such studies is the situational context in which risk behavior is embedded: Even though a person may perceive a behavior as risky, the social norms governing the situation may work as a counteracting force, overriding the influence of risk perception. Three food context studies are reported. In Study 1 (N = 200), we assess how norm strength varies across different social situations, relate the variation in norm strength to the social characteristics of the situation, and identify situations with consistently low and high levels of pressure to comply with the social norm. In Study 2 (N = 502), we investigate how willingness to accept 15 different foods that vary in terms of objective risk relates to perceived risk in situations with low and high pressure to comply with a social norm. In Study 3 (N = 1,200), we test how risk-taking is jointly influenced by the perceived risk associated with the products and the social norms governing the situations in which the products are served. The results indicate that the effects of risk perception and social norm are additive, influencing risk-taking simultaneously but as counteracting forces. Social norm had a slightly stronger absolute effect, leading to a net effect of increased risk-taking. The relationships were stable over different social situations and food safety risks and did not disappear when detailed risk information was presented., (© 2020 The Authors.

Introduction: The purpose of this systematic review was to explore perceived diabetes risk with foci on prediabetic persons and Asian Americans. Persons with prediabetes and of Asian descent are at higher risk for developing diabetes, but little is known about their perceived diabetes risk. Method: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guided this systematic review. Electronic searches were conducted in three databases. The authors conducted eligibility determination, data extraction, synthesis, and evaluation. Twelve articles were selected. Results: Key findings include (1) limited studies including Asian populations, (2) a low percentage of persons in the general population with moderate to high levels of perceived diabetes risk, (3) a lack of congruency between actual and perceived diabetes risk in the general population, and (4) no interventions effectively changing the level of perceived diabetes risk. Discussion: More studies regarding perceived diabetes risk are needed, especially with a focus on Asian Americans.

Background: A positive family history of type 2 diabetes (T2D) has been associated with risk awareness and risk-reducing behaviours among the unaffected relatives. Yet, little is known about how people with a positive family history for diabetes develop and manage their personal sense of risk., Objective: To characterize two key concepts, salience and vulnerability, within the familial risk perception (FRP) model among unaffected individuals, at increased familial risk for T2D., Design: We conducted a mixed method study. Descriptions of salience and vulnerability were collected through semi-structured interviews. Participant's perception of self-reported risk factors (family history, age, race/ethnicity, medical history, weight and exercise) was measured using the Perceived Risk Factors for T2D Tool and was compared to a clinical evaluation of the same risk factors., Results: We identified two components of salience: (a) concern for developing T2D and (b) risk awareness triggers, and two features of vulnerability: (a) statement of risk and (b) risk assessment devices. Although few participants (26%) were concordant between their perceived and clinical overall T2D risk, concordance for individual risk factors was higher, ranging from 42% (medical history) to 90% (family history)., Discussion and Conclusion: Both familial and non-familial events lead people to contemplate their T2D risk, even among people who have a positive family history. Participants often downplayed their overall risk and underestimated their overall risk compared to a clinical risk assessment of the same self-reported risk factors. Clinicians could leverage key components of the FRP process as way to engage patients in risk reduction strategies earlier., (© 2019 The Authors Health Expectations published by John Wiley & Sons Ltd.)

Based on survey data from 327 rural households in the areas affected by the Wenchuan Earthquake and Lushan Earthquake in Sichuan Province, this study systematically analyzed disaster risk perception, sense of place, evacuation willingness, and relocation willingness among residents in these earthquake-stricken areas. Further, this study constructed an ordinal logistic regression analysis to probe the correlations between residents' disaster risk perception or sense of place and evacuation willingness and relocation willingness, respectively. The results showed that (1) faced with the threat of earthquake disasters, residents have a strong willingness to evacuate and relocate. Specifically, 93% and 78% of the residents in the Wenchuan Earthquake and Lushan Earthquake areas were willing to evacuate and relocate, respectively, whereas 4% and 17% of the residents were unwilling to evacuate and relocate, respectively. (2) Place dependence and the severity of disaster occurrence were significantly positively correlated with residents' evacuation willingness, while the interaction term between place dependence and the severity of disaster occurrence was negatively related to residents' evacuation willingness. Specifically, when everything else remains constant, every one-unit increase in place dependence and severity corresponds to increases in the odds of willingness to evacuate by factors of 0.042 and 0.051, respectively; every one-unit increase in place dependence × severity corresponds to a decrease in the odds of willingness to evacuation by a factor of 0.004. (3) Place identity was significantly negatively correlated with residents' relocation willingness, while place dependence and severity of disaster occurrence were positively related to residents' relocation willingness. The interaction term between place dependence and the severity of disaster occurrence as well as the interaction term between place identity and severity of disaster occurrence were significantly negatively correlated with residents' relocation willingness. Specifically, every one-unit increase in place identity corresponds to a decrease in the odds of willingness to relocate by a factor of 0.034, while every one-unit increase in place dependence and severity corresponds to increases in the odds of willingness to relocate by factors of 0.041 and 0.028, respectively, and every one-unit increase in place dependence × severity and place identity × severity corresponds to decreases in the odds of willingness to relocate by factors of 0.003 and 0.003, respectively.

This mixed-methods study investigated consumers' knowledge of chemicals in terms of basic principles of toxicology and then related this knowledge, in addition to other factors, to their fear of chemical substances (i.e., chemophobia). Both qualitative interviews and a large-scale online survey were conducted in the German-speaking part of Switzerland. A Mokken scale was developed to measure laypeople's toxicological knowledge. The results indicate that most laypeople are unaware of the similarities between natural and synthetic chemicals in terms of certain toxicological principles. Furthermore, their associations with the term "chemical substances" and the self-reported affect prompted by these associations are mostly negative. The results also suggest that knowledge of basic principles of toxicology, self-reported affect evoked by the term "chemical substances," risk-benefit perceptions concerning synthetic chemicals, and trust in regulation processes are all negatively associated with chemophobia, while general health concerns are positively related to chemophobia. Thus, to enhance informed consumer decisionmaking, it might be necessary to tackle the stigmatization of the term "chemical substances" as well as address and clarify prevalent misconceptions., (© 2019 Society for Risk Analysis.)

Rural communities dependent on unregulated drinking water are potentially at increased health risk from exposure to contaminants. Perception of drinking water safety influences water consumption, exposure, and health risk. A community-based participatory approach and probabilistic Bayesian methods were applied to integrate risk perception in a holistic human health risk assessment. Tap water arsenic concentrations and risk perception data were collected from two Saskatchewan communities. Drinking water health standards were exceeded in 67% (51/76) of households in Rural Municipality #184 (RM184) and 56% (25/45) in Beardy's and Okemasis First Nation (BOFN). There was no association between the presence of a health exceedance and risk perception. Households in RM184 or with an annual income >$50,000 were most likely to have in-house water treatment. The probability of consuming tap water perceived as safe (92%) or not safe (0%) suggested that households in RM184 were unlikely to drink water perceived as not safe. The probability of drinking tap water perceived as safe (77%) or as not safe (11%) suggested households in BOFN contradicted their perception and consumed water perceived as unsafe. Integration of risk perception lowered the adult incremental lifetime cancer risk by 3% to 1.3 × 10 -5 (95% CI 8.4 × 10 -8 to 9.0 × 10 -5 ) for RM184 and by 8.9 × 10 -6 (95% CI 2.2 × 10 -7 to 5.9 × 10 -5 ) for BOFN. Probability of exposure to arsenic concentrations >1:100,000, negligible cancer risk, was 23% for RM184 and 22% for BOFN., (© 2019 Society for Risk Analysis.)

New food technologies have a high potential to transform the current resource-consuming food system to a more efficient and sustainable one, but public acceptance of new food technologies is rather low. Such an avoidance might be maintained by a deeply preserved risk avoidance system called disgust. In an online survey, participants (N = 313) received information about a variety of new food technology applications (i.e., genetically modified meat/fish, edible nanotechnology coating film, nanotechnology food box, artificial meat/milk, and a synthetic food additive). Every new food technology application was rated according to the respondent's willingness to eat (WTE) it (i.e., acceptance), risk, benefit, and disgust perceptions. Furthermore, food disgust sensitivity was measured using the Food Disgust Scale. Overall, the WTE both gene-technology applications and meat coated with an edible nanotechnology film were low and disgust responses toward all three applications were high. In full mediation models, food disgust sensitivity predicted the disgust response toward each new food technology application, which in turn influenced WTE them. Effects of disgust responses on the WTE a synthetic food additive were highest for and lowest for the edible nanotechnology coating film compared to the other technologies. Results indicate that direct disgust responses influence acceptance and risk and benefit perceptions of new food technologies. Beyond the discussion of this study, implications for future research and strategies to increase acceptance of new food technologies are discussed., (© 2019 The Authors Risk Analysis published by Wiley Periodicals, Inc. on behalf of Society for Risk Analysis.)

Rationale: Although greater attention has been recently given to the ecological determinants of health behaviours, we still do not know much about the behavioural changes induced by the spread of infectiousdiseases., Objective: In this study, we took advantage of a large epidemic of chikungunya, an emerging mosquito-borne disease, in French Guiana to examine the dynamic interaction between risk-related perceptions and behaviours that occurs in response to a disease outbreak. In particular, we tested empirically the assumption that both risk perceptions and health behaviours were elastic with respect to prevalence of chikungunya., Methods: A representative sample of French Guianan (N=434) was interviewed in January 2015 just after the peak of the epidemic, and again 2 months later. Participants were asked about their perceptions of the threat, as well as their engagement in a range of protective behaviours promoted by the regional health authorities to control the spread of the disease., Results: The surveys showed that (1) the frequency of some health behaviours - those related to visible control methods - significantly increased with the subjective and objective prevalence of the disease, (2) perceived risk of infection for oneself tended to decrease considerably over time, and (3) the risk reappraisal hypothesis failed to account for this paradoxical trend in the people's response to the risk of contracting the disease., Conclusion: These findings suggest that people may fail to adjust their risk perceptions, and to a lesser extent their health protective behaviours, to the course of an epidemic. Notably, the prevalence elasticity of preventive action found in previous studies of behavioural response to infectious diseases differed substantially according to the type of intervention (personal versus environmental methods). This paradoxical trend may be attributed to risk habituation effects, which seem to vary significantly according to the social visibility of thepreventive actions., (Copyright © 2019 Elsevier Ltd.

The present study investigated expatriate humanitarian aid workers' perceptions and responses to uncertain security while deployed in the Sudan. Interviews conducted in Khartoum (n = 7) and Darfur (n = 17) focused on risk perception, concern for personal security, and strategies used to function well in an insecure environment. Despite a high perceived general risk, as well as broad knowledge and experience with security incidents, participants often expressed low concern. General adjustment processes were drawn on to explain this finding, while different constellations of processes resulted in different patterns of adjustment. Functional adjustment, resulting in adequate risk perception, protective behavior, protection, and low concern, was characterized by a constellation of complementary activation of accommodation and assimilation processes., (© 2018 Society for Risk Analysis.)

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., (© 2018 Society for Risk Analysis.)

The main purpose of the article is to examine the association between risk perception and cyclists' decision as to whether to cycle during the different seasons of the year. The study on which the article is based included worry as a feeling that emerges as a result of an individual's cognitive assessment of risk, attitudes toward traffic rules, risk tolerance and safety priority. The study was based on a questionnaire survey carried out among cyclists from Trondheim Municipality in Norway (n = 291) during spring 2017. The results revealed seasonal differences in perceived risk and that risk perception was an important predictor of both the decision as to whether to cycle and the frequency of cycling during wintertime. The same results were not found for cycling during the other seasons of the year. Additionally, an association was found between risk perception and worry. The respondents were more worried when cycling in winter conditions compared with cycling in summer conditions, and worry was a strong predictor of travel mode behaviour. The authors found that when the respondents' perception of risk was very low, they were not worried and hence their behaviour was not affected. Perceived risk and worry were only associated with cycling behaviour during wintertime. These findings may be used as a guide in measures implemented to increase the number of cyclists during winter and in communications to the public about the risks linked to cycling., (Copyright © 2018 Elsevier Ltd.

Hydraulic fracturing has provided a persistent, polarizing, and highly politicized source of controversy internationally and in numerous national contexts for just under a decade. This research uses hydraulic fracturing (i.e., fracking) operations in New Zealand as a vignette through which to understand the underlying causes of controversy and the appropriateness of attempts to address them. A multi-method approach using interviews (n = 25), diagrammatic analysis, and newsprint media was applied to evidence two major findings. First, previous attempts to explain fracking controversy based on social constructivist theory lack a multi-scalar approach to the assessment of factors that influence risk perceptions. It is found that risk perception surrounding fracking in New Zealand reflects intra-scalar interactions between factors originating at the international, national, regional, and local scale. Second, there is a concerning absence of critique pertaining to the concept of "social license to operate" (SLO), which has been advocated both internationally and nationally as an appropriate form of stakeholder engagement. This article contributes to the SLO outcomes literature by establishing a need to consider multi-scalar influences on risk perception when explaining diverse SLO outcomes in communities where fracking operations are prospective or already taking place., (© 2018 The Authors Risk Analysis published by Wiley Periodicals, Inc. on behalf of Society for Risk Analysis.)

The increasing development of autonomous vehicles (AVs) influences the future of transportation. Beyond the potential benefits in terms of safety, efficiency, and comfort, also potential risks of novel driving technologies need to be addressed. In this article, we explore risk perceptions toward connected and autonomous driving in comparison to conventional driving. In order to gain a deeper understanding of individual risk perceptions, we adopted a two-step empirical procedure. First, focus groups ( N = 17 ) were carried out to identify relevant risk factors for autonomous and connected driving. Further, a questionnaire was developed, which was answered by 516 German participants. In the questionnaire, three driving technologies (connected, autonomous, conventional) were evaluated via semantic differential (rating scale to identify connotative meaning of technologies). Second, participants rated perceived risk levels (for data, traffic environment, vehicle, and passenger) and perceived benefits and barriers of connected/autonomous driving. Since previous experience with automated functions of driver assistance systems can have an impact on the evaluation, three experience groups have been formed. The effect of experience on benefits and barrier perceptions was also analyzed. Risk perceptions were significantly smaller for conventional driving compared to connected/autonomous driving. With increasing experience, risk perception decreases for novel driving technologies with one exception: the perceived risk in handling data is not influenced by experience. The findings contribute to an understanding of risk perception in autonomous driving, which helps to foster a successful implementation of AVs on the market and to develop public information strategies., (© 2018 Society for Risk Analysis.)

Stroke continues to be a public health problem, and risk perceptions are key to understanding people's thoughts about stroke risk and their preventive health behaviors. This review identifies how the perceived risk of stroke has been measured and outcomes in terms of levels, predictors, accuracy, and intervention results. Sixteen studies were included. The perceived risk of stroke has primarily been assessed with single-item measures; no multi-item surveys were found. In general, people tend to perceive a low-moderate risk of stroke; the most common predictors of higher stroke risk perceptions were having risk factors for stroke (hypertension, diabetes) and a higher number of risk factors. However, inaccuracies were common; at least half of respondents underestimated/overestimated their risk. Few studies have examined whether interventions can improve the perceived risk of stroke. Strategies to improve stroke risk perceptions should be explored to determine whether accuracy can promote healthy lifestyles to reduce stroke risk.

Effectively communicating the risks associated with emerging zoonotic diseases remains an important challenge. Drawing on research into the psychological effects of metaphoric framing, we explore the conditions under which exposure to the "nation as a body" metaphor influences perceived risk susceptibility, behavioral intentions, and policy support in the context of Zika virus. In a between-subjects experiment, 354 U.S. adults were randomly assigned to one of four experimental conditions as part of a 2 (severity message: high vs. low) × 2 (U.S. framing: metaphoric vs. literal) design. Results revealed an interaction effect such that metaphoric (vs. literal) framing increased perceived risk susceptibility in the high-severity condition only. Further analyses revealed that perceived risk susceptibility and negative affect mediated the path between the two-way interaction and policy support and behavioral intentions regarding Zika prevention. Overall, these findings complement prior work on the influence of metaphoric framing on risk perceptions, while offering practical insights for risk communicators seeking to communicate about Zika and other zoonotic diseases., (© 2018 Society for Risk Analysis.)

Subjective risk perception during urban cycling has been mostly investigated through questionnaire studies. However, newly available data sources promise extended possibilities for the investigation and understanding of the underlying factors. We validate the rationale for using both opportunistically available crowd-sourced data (i.e., volunteered geographic information or VGI) as well as more established but rarely investigated authoritative data as predictors of subjective cycling risk. We achieve this by correlating indicators of cycling risk extracted from both VGI and authoritative data for two different German cities with participants' risk estimates assessed in laboratory-based virtual reality experiments. In Case 1, 15 participants (mostly undergraduate students with a mean age of 22 years old; nine of them females) were tested as a sample representing frequent and experienced cyclists, but unfamiliar with the 19 tested locations and less likely to be affected by the virtual reality setup. In Case 2, 24 new participants (mostly undergraduate students; mean age 24 years; 13 of them females) were experienced cyclists and mostly familiar with the 40 test locations located in their city of residence. For both cases, our findings provide evidence that parameters extracted from VGI (e.g., the semantic severity of the contribution and the reception by other citizens) as well as from authoritative data sources (e.g., accident statistics or Space Syntax measures) represent valid indicators for the subjectively perceived risk of cycling at a specific location. On the basis of this validation, future research can use these data sources to investigate the sources of risk perception during urban cycling in greater detail., (Copyright © 2018 Elsevier Ltd.

News media plays a large role in the information the public receives during an infectious disease outbreak, and may influence public knowledge and perceptions of risk. This study analyzed and described the content of U.S. news media coverage of Zika virus and Zika response during 2016. A random selection of 800 Zika-related news stories from 25 print and television news sources was analyzed. The study examined 24 different messages that appeared in news media articles and characterized them using theories of risk perception as messages with characteristics that could increase perception of risk (risk-elevating messages; n = 14), messages that could decrease perception of risk (risk-minimizing messages; n = 8), or messages about travel or testing guidance (n = 2). Overall, 96% of news stories in the study sample contained at least one or more risk-elevating message(s) and 61% contained risk-minimizing message(s). The frequency of many messages changed after local transmission was confirmed in Florida, and differed between sources in locations with or without local transmission in 2016. Forty percent of news stories included messages about negative potential outcomes of Zika virus infection without mentioning ways to reduce risk. Findings from this study may help inform current federal, state, and local Zika responses by offering a detailed analysis of how news media are covering the outbreak and response activities as well as identifying specific messages appearing more or less frequently than intended. Findings identifying the types of messages that require greater emphasis may also assist public health communicators in responding more effectively to future outbreaks., (© 2017 Society for Risk Analysis.)

Background: Making tobacco products associated with lower risks available to smokers who would otherwise continue smoking is recognized as an important strategy towards addressing smoking-related harm. Predicting use behavior is an important major component of product risk assessment. In this context, risk perception is a possible factor driving tobacco product uptake and use. As prior to market launch real-world actual product use cannot be observed, assessing risk perception can provide predictive information. Considering the lack of suitable validated self-report instruments, the development of a new instrument was undertaken to quantify perceived risks of tobacco and nicotine-containing products by adult smokers, former smokers and never-smokers., Methods: Initial items were constructed based on a literature review, focus groups and expert opinion. Data for scale formation and assessment were obtained through two successive US-based web surveys (n = 2020 and 1640 completers, respectively). Psychometric evaluation was based on Rasch Measurement Theory and Classical Test Theory., Results: Psychometric evaluation supported the formation of an 18-item Perceived Health Risk scale and a 7-item Perceived Addiction Risk scale: item response option thresholds were ordered correctly for all items; item locations in each scale were spread out (coverage range 75-87%); scale reliability was supported by high person separation indices > 0.93, Cronbach's alpha > 0.98 and Corrected Item-Total Correlations > 0.88; and no differential item functioning was present. Construct validity evaluations met expectations through inter-scale correlations and findings from known-group comparisons., Conclusions: The Perceived Risk Instrument is a psychometrically robust instrument applicable for general and personal risk perception measurement, for use in different types of products (including cigarettes, nicotine replacement therapy, potential Modified Risk Tobacco Products), and for different smoking status groups (i.e., current smokers with and without intention to quit, former smokers, never smokers).

Background: Uruguay, a South American country of 3.4 million inhabitants that has already banned tobacco advertising, prohibited such terms as light, mild and low-tar and required graphic warnings covering 80% of cigarette packs, is considering the imposition of plain, standardised packaging., Methods: We conducted an experimental choice-based conjoint analysis of the impact of alternative cigarette package designs on the risk perceptions of 180 adult current Uruguayan smokers. We compared plain packaging, with a standardised brand description and the dark brown background colour required on Australian cigarette packages, to two controls: the current package design with distinctive brand elements and colours; and a modified package design, with distinctive brand elements and the dark brown background colour. Graphic warnings were also varied., Results: Plain packaging significantly reduced the probability of perceiving the stimulus cigarettes as less harmful in comparison to the current package design (OR 0.398, 95% CI 0.333 to 0.476, p<0.001) and the modified package design (OR 0.729, 95% CI 0.626 to 0.849, p<0.001)., Conclusions: Plain packaging enhanced the perceived risk of cigarette products even in a highly regulated setting such as Uruguay. Both the elimination of distinctive brand elements and the use of Australia's dark brown background colour contributed to the observed effect., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Introduction: A mosaic of evidence links risk perceptions with drug use in adolescence, including population summaries to guide public health campaigns, as well as subject-specific estimates on preventing an adolescent's drug use by manipulating that individual's prior risk perceptions. We re-visit these issues with a public health perspective, asking whether population-level cannabis risk perceptions of school-attending adolescents at one grade level might predict cannabis use prevalence two and four grade levels later., Methods: From 1991 to 2014, each year's United States "Monitoring the Future" (MTF) study population included 8th-, 10th-, & 12th-graders. Two and four years later, statistically independent school samples of the same cohorts were drawn and assessed (n ~ 16,000/year). Population-level modeling estimated cannabis use prevalence at time "t" (12th-grade) regressed on that same cohort's cannabis risk perceptions as had been measured at time "t-4" (8th-grade) and time "t-2" (10th-grade)., Results: Higher cannabis risk perception levels for 10th-graders predict lower cannabis use prevalence when 10th-graders have become 12th-graders (β̂=-0.12), and higher cannabis risk perception levels of 8th-graders predict lower cannabis prevalence when 8th-graders have become 10th-graders (β̂=-0.27); p-values < 0.05. Across four-year spans, the prediction is null (p-value = 0.619)., Conclusions: This within-cohort across-grade population-level prediction prompts questions for drug prevention specialists, including "Would a relatively small upward shift in a local area population's appraisal of risk perceptions be followed, two years later, by reduced population prevalence of cannabis use?" Future randomized trial designs, health education, or prevention efforts focused on altering early adolescent cannabis risk perceptions might provide the most convincing and definitive evidence., (Copyright © 2018 Elsevier Ltd.

Purpose: The current project sought to examine whether delivery of lung cancer risk projections (calculated using the Liverpool Lung Project [LLP] risk model) predicted follow-up smoking status., Design: Two single-blinded randomized controlled trials., Setting: Stop Smoking Services in Liverpool (United Kingdom)., Participants: Baseline current smokers (N = 297) and baseline recent former smokers (N = 216) were recruited., Intervention: Participants allocated to intervention groups were provided with personalized lung cancer risk projections, calculated using the LLP risk model., Measures: Baseline and follow-up questionnaires explored sociodemographics, smoking behavior, and lung cancer risk perceptions., Analysis: Bivariate analyses identified significant differences between randomization groups, and logistic regression models were developed to investigate the intervention effect on the outcome variables., Results: Lung cancer risk projections were not found to predict follow-up smoking status in the trial of baseline current smokers; however, they did predict follow-up smoking status in the trial of baseline recent former smokers (odds ratio: 1.91; 95% confidence interval: 1.03-3.55)., Conclusion: The current study suggests that lung cancer risk projections may help maintain abstinence among individuals who have quit smoking, but the results did not provide evidence to suggest that lung cancer risk projections motivate current smokers to quit.

This study aims to assess the relationship between risk perception, attitude, and avoidance among residents toward an urban incinerator in Taichung, Taiwan. A cross-sectional study was conducted and three schools were enrolled. The case group was composed of 514 residents who live near an incinerator. The control group was composed of 264 people nearly the same age and who have lived in that area basically the same period of time. All participants were interviewed using a structured questionnaire. Results of this study showed that there was no significant difference between the exposure group and the control group in risk perception and attitude regarding the incinerator. However, the exposure group showed a significantly higher desire to move within one year or move sometime in the future than the control group. Therefore, these people should encourage the Environmental Protection Administration (EPA) to do everything it can to make sure that the incinerator operates safely.

Objective: The current study investigated how adolescents perceive their own health risks and compare their own likelihood of health risks with that of others of the same age. Moreover, the study identified the differences in health risk perceptions between males and females., Methods: A total of 625 adolescents (314 males and 311 females) from the Nowon district, geographically located in northern Seoul, voluntarily participated. In order to measure health risk perceptions a Korean version of self-other risk judgments profile was used., Results: The findings indicated that study participants, regardless of gender and age, tend to underestimate their vulnerability to majority of health risk events. Furthermore, there were significant gender and age differences in health risk perception and perception bias in all health risk domains., Conclusion: The present study suggests that further research is needed to identify realistic and unrealistic perception mechanism for a large number of people from different demographic and socioeconomic backgrounds., (Copyright© by the National Institute of Public Health, Prague 2018.)

Helping breast cancer patients who desire a pregnancy after cancer treatment is a vital issue. Little is known about the complex context of the decision to become pregnant after breast cancer treatment. The purpose of this study was to understand the risk-benefit perception of choosing conception or contraception after treatment in Taiwan. We applied grounded theory to guide this exploratory qualitative study. Data were collected through in-depth interviews with 16 breast cancer patients. Pregnancy was addressed in the context of cancer as a potentially life-threatening diagnosis and its treatment. The verbatim transcriptions were analysed using constant comparative analysis and methods of open, axial and selective coding. The core theme that described the risk perception of pregnancy among patients with breast cancer after treatment focused on "reaching the balance of life." Seven dimensions of risk-benefit perception of pregnancy, including perceived health status, safety, expected gain, harm, loading, support and time were explored among women treated for breast cancer. We found that women treated for breast cancer applied risk-benefit perceptions to decide whether to become pregnant. Implementing contextual counselling could help to decrease perceived barriers to choose pregnancy and increase the quality of pregnancy care., (© 2017 John Wiley & Sons Ltd.)

In this study, we compared subjective fracture risks of Hungarian women with osteoporosis to FRAX®-based estimates. Patients with a previous fracture, parental hip fracture, low femoral T-score, higher age, and higher BMI were more likely to underestimate their risks. Patients also failed to associate risk factors with an increased risk of fractures., Purpose: The main objectives were to explore associations between self-perceived 10-year fracture risks of women with osteoporosis (OP) and their risks calculated by the FRAX® algorithm and to identify determinants of the underestimation of risk., Methods: We carried out a cross-sectional study in 11 OP centers in Hungary and collected data on the risk factors considered by the FRAX® calculator. Patients estimated their subjective 10-year probability of any major osteoporotic and hip fracture numerically, in percentages and also on a visual analog scale (VAS). We compared subjective and FRAX® estimates and applied logistic regression to analyze the determinants of the underestimation of risk. Associations between risk factors and subjective risk were explored using linear probability models., Results: Nine hundred seventy-two OP patients were included in the analysis. Major OP and hip fracture risk by FRAX® were on average 20.1 and 10.5%, while subjective estimates were significantly higher, 30.0 and 24.7%, respectively. Correlations between FRAX® and subjective measures were very weak (r = 0.12-0.16). Underestimation of major OP fracture risk was associated with having had a single previous fracture (OR = 2.0), parental hip fracture (OR = 3.4), femoral T-score ≤-2.5 (OR = 4.2), higher age, body mass index, and better general health state. We did not find significant associations between subjective risk estimates and most of the risk factors except for previous fractures., Conclusions: Hungarian OP patients fail to recognize most of the risk factors of fractures. Thus, education of patients about these risk factors would be beneficial especially for the elderly with a low femoral T-score and parental hip fracture history.

While risk perception is a key factor influencing safety behavior, the academia lacks specific attention to the ways that workers perceive risk, and thus little is known about the mechanisms through which different risk perceptions influence safety behavior. Most previous research in the workplace safety domain argues that people tend to perceive risk based on rational formulations of risk criticality. However, individuals' emotions can be also useful in understanding their perceptions. Therefore, this research employs an integrated analysis concerning the rational and emotional perspectives. Specifically, it was expected that the identified three rational ways of perceiving risk, i.e., perceived probability, severity, and negative utility, would influence the direct emotional risk perception. Furthermore, these four risk perceptions were all expected to positively but differently influence safety behavior. The hypotheses were tested using a sample of 120 construction workers. It was found that all the three rational risk perceptions significantly influenced workers' direct perception of risk that is mainly based on emotions. Furthermore, safety behavior among workers relied mainly on emotional perception but not rational calculations of risk. This research contributes to workplace safety research by highlighting the importance of integrating the emotional assessment of risk, especially when workers' risk perception and behavior are concerned. Suggested avenues for improving safety behavior through improvement in risk perception include being aware of the possibility of different ways of perceiving risk, promoting experience sharing and accident simulation, and uncovering risk information., (Copyright © 2017 Elsevier Ltd.

Background: Internet-based cancer risk assessment tools might serve as a strategy for translating epidemiological risk prediction research into public health practice. Understanding how such tools affect key social-cognitive precursors of behavior change is crucial for leveraging their potential into effective interventions., Purpose: To test the effects of a publicly available, Internet-based, breast cancer risk assessment tool on social-cognitive precursors of physical activity., Methods: Women (N = 132) aged 40-78 with no personal cancer history indicated their perceived risk of breast cancer and were randomly assigned to receive personalized ( www.yourdiseaserisk.wustl.edu ) or nonpersonalized breast cancer risk information. Immediately thereafter, breast cancer risk perceptions and physical activity-related behavioral intentions, self-efficacy, and response efficacy were assessed., Results: Personalized information elicited higher intentions, self-efficacy, and response efficacy than nonpersonalized information, P values < 0.05. Self-efficacy and response efficacy mediated the effect of personalizing information on intentions. Women who received personalized information corrected their inaccurate risk perceptions to some extent, P values < 0.05, but few fully accepted the information., Conclusion: Internet-based risk assessment tools can produce beneficial effects on important social-cognitive precursors of behavior change, but lingering skepticism, possibly due to defensive processing, needs to be addressed before the effects can be maximized.

This paper draws on interview data to examine how international health care workers navigated risk during the unprecedented Ebola outbreak in West Africa. It identifies the importance of place in risk perception, including how different spatial localities give rise to different feelings of threat or safety, some from the construction of physical boundaries, and others mediated through aspects of social relations, such as trust, communication and team dynamics. Referring to these spatial localities as 'riskscapes', the paper calls for greater recognition of the role of place in understanding risk perception, and how people navigate risk., (Copyright © 2017 Elsevier Ltd.

Recollection bias is the phenomenon whereby people who observe a highly unexpected event hold current risk beliefs about a similar event that are no higher than their recollection of their prior beliefs. This article replicates and extends the authors' previous study of recollection bias in relation to individuals' perceptions of the risks of terrorism attacks. Over 60% of respondents in a national U.S. sample of over 900 adults believe that the current risk of a future terrorist attack by either an airplane or in a public setting is no higher than they recall having believed, respectively, before the 9/11 attack and before the Boston Marathon bombing. By contrast, a rational Bayesian model would update to a higher currently assessed risk of these previously uncontemplated events. Recollection bias is a persistent trait: individuals who exhibited this bias for the 9/11 attack exhibited it for the Boston Marathon bombing. Only one-fifth of respondents are free of any type of recollection bias. Recollection bias is negatively correlated with absolute levels of risk belief. Recollection bias in relation to highly unexpected terrorist events-the belief that perceived risks did not increase after the surprise occurrence-dampens support for a variety of anti-terrorism measures, controlling for the level of risk beliefs and demographic factors. Persistent recollection bias for both 9/11 and the Boston Marathon bombing is especially influential in diminishing support for protective policy measures, such as surveillance cameras in public places. Given that public attitudes influence policy, educating the public about risk is critical., (© 2017 Society for Risk Analysis.)

This study investigated the food risk perceptions of people living in the Triveneto area (Northeast Italy), a territory characterized by a particular interest in the production of quality foodstuffs, to determine what aspects people associate with food risk and to understand what beliefs underlie these perceptions. Four focus groups were conducted in the major towns of the target area (N = 45). A semi-structured interview was used that focused on beliefs about food risks, the use of information and media sources in relation to food risk, and the behaviours adopted when eating outside the home. A homogeneous view of food risk emerged among the respondents, and a common definition of risky food was identified. The concept of risk was in opposition to the quality and controllability of food, which emerged as major strategies to cope with food risks. Quality was linked to freshness and local origin, whereas controllability reflected a direct (e.g., checking labels, having a relationship with the vendor, cultivating one's own vegetable garden) or indirect (e.g., control guarantees provided by suppliers and the government) means to check the safety and quality of food. Although people seemed quite informed about food risks, a common sense of impotence with regard to one's own protection prevailed, together with a fatalistic sense of incomplete control over risk. The results identified food concerns for consumers living in this specific territory and might represent a starting point for public health authorities to increase compliance with responsible behaviours for risk mitigation and to define successful food policies for this area., (Copyright © 2016 Elsevier Ltd.

Research into how people perceive risk has highlighted the interaction between the available information and personal variables and their impact on judgement. This study sought to identify demographic and health variables that influenced risk and the influence of individual risk assessment, dispositional optimism and negative affect on judgement. A total of 476 participants were asked to make risks judgements of 24 vignettes depicting hypothetical risk scenarios. The findings showed that while people are able to correctly recognise, in others, relevant risk factors for coronary heart disease, risk perception is likely to imply a personal consideration of the same risk factors in themselves.

The media play an important role in risk communication, providing information about accidents, both nearby and far away. Each media source has its own presentation style, which could influence how the audience perceives the presented risk. This study investigates the explanatory power of 12 information sources (traditional media, new media, social media, and interpersonal communication) for the perceived risk posed by radiation released from the damaged Fukushima nuclear power plant on respondents' own health and that of the population in general. The analysis controlled for attitude toward nuclear energy, gender, education, satisfaction with the media coverage, and duration of attention paid to the coverage. The study uses a large empirical data set from a public opinion survey, which is representative for the Belgian population with respect to six sociodemographic variables. Results show that three information sources are significant regressors of perceived health-related risk of the nuclear accident: television, interpersonal communication, and the category of miscellaneous online sources. More favorable attitudes toward nuclear power, longer attention to the coverage, and higher satisfaction with the provided information lead to lower risk perception. Taken together, the results suggest that the media can indeed have a modest influence on how the audience perceives a risk., (© 2016 Society for Risk Analysis.)

As the environmental remediation industry matures, remaining sites often have significant underlying technical challenges and financial constraints. More often than not, significant remediation efforts at these "complex" sites have not achieved stringent, promulgated cleanup goals. Decisions then have to be made about whether and how to commit additional resources towards achieving those goals, which are often not achievable nor required to protect receptors. Guidance on cleanup approaches focused on evaluating and managing site-specific conditions and risks, rather than uniformly meeting contaminant cleanup criteria in all media, is available to aid in this decision. Although these risk-based cleanup approaches, such as alternative endpoints and adaptive management strategies, have been developed, they are under-utilized due to environmental, socio-economic, and risk perception barriers. Also, these approaches are usually implemented late in the project life cycle after unsuccessful remedial attempts to achieve stringent cleanup criteria. In this article, we address these barriers by developing an early decision framework to identify if site characteristics support sustainable risk management, and develop performance metrics and tools to evaluate and implement successful risk-based cleanup approaches. In addition, we address uncertainty and risk perception challenges by aligning risk-based cleanup approaches with the concepts of risk management and sustainable remediation. This approach was developed in the context of lessons learned from implementing remediation at complex sites, but as a framework can, and should, be applied to all sites undergoing remediation., (Copyright © 2016 Elsevier Ltd.

Background: Personalised health-risk assessment is one of the most common components of health promotion programs. Previous research on responses to health risk feedback has commonly focused on the reception of bad news (high-risk feedback). The reception of low-risk feedback has been comparably neglected since it is assumed that good news is reassuring and readily received. However, field studies suggest mixed responses to low-risk health feedback. Accordingly, we examine whether pre-feedback risk expectancies can mitigate the reassuring effects of good news., Methods: In two studies (N = 187, N = 565), after assessing pre-feedback risk expectancies, participants received low-risk personalised feedback about their own risk of developing (the fictitious) Tucson Chronic Fatigue Syndrome (TCFS). Study 2 also included peer TCFS risk status feedback. Afterwards, self- and peer-related risk perception for TCFS was assessed., Results: In both studies, participants who expected to be at high risk but received good news (unexpected low-risk feedback) showed absolute lack of reassurance. Specifically, they felt at significantly greater TCFS risk than participants who received expected good news. Moreover, the unexpected low-risk group even believed that their risk was as high as (Study 1) or higher (Study 2) than that of their peers (comparative lack of reassurance)., Conclusion: Results support the notion that high pre-feedback risk expectancies can mitigate absolute and comparative reassuring effects of good news., (© 2016 The International Association of Applied Psychology.)
