Using Geovisualizations to Educate the Public About Environmental Health Hazards: What Works and Why

PURPOSE OF REVIEW

Informing the public about environmental risks to health is crucial for raising awareness around hazards, and promoting actions that minimize exposures. Geographic visualizations-geovisualizations-have become an increasingly common way to disseminate web-based information about environmental hazards, displaying spatial variations in exposures and health outcomes using a map. Unfortunately, ineffective geovisualizations can result in inaccurate inferences about a hazard, leading to misguided actions or policies. In this narrative review, we discuss key considerations for the use of geovisualizations to promote environmental health literacy.

RECENT FINDINGS

Many conventional geovisualizations used for hazard education and risk communication fail to consider how people process visual information. Design choices that prompt viewers to think and feel, leveraging processes such as individual attention, memory, and emotion, could promote improved comprehension and decision making around environmental health risks using geovisualizations. Based on the studies reviewed, we recommend six strategies for designing effective, evidence-based geovisualizations, synthesizing evidence from the cognitive sciences, cartography, and environmental health. These strategies include: Displaying only key data, tailoring and testing geovisualizations with the desired audience, using salient cues, leveraging emotion, aiding pattern recognition, and limiting visual distractions. Geovisualizations offer a promising avenue for advancing public awareness and fostering proactive measures in addressing complex environmental health challenges. This review highlights how incorporating evidence-based design principles into geovisualizations could promote environmental health literacy. More experimental research evaluating geovisualizations, using interdisciplinary approaches, is needed.

Fast & slow decisions under risk: Intuition rather than deliberation drives advantageous choices

Would you take a gamble with a 10% chance to gain $100 and a 90% chance to lose $10? Even though this gamble has a positive expected value, most people would avoid taking it given the high chance of losing money. Popular "fast-and-slow" dual process theories of risky decision making assume that to take expected value into account and avoid a loss aversion bias, people need to deliberate. In this paper we directly test whether reasoners can also consider expected value benefit intuitively, in the absence of deliberation. To do so, we presented participants with bets and lotteries in which they could choose between a risky expected-value-based choice and a safe loss averse option. We used a two-response paradigm where participants made two choices in every trial: an initial intuitive choice under time-pressure and cognitive load and a final choice without constraints where they could freely deliberate. Results showed that in most trials participants were loss averse, both in the intuitive and deliberate stages. However, when people opted for the expected-value-based choice after deliberating, they had predominantly already arrived at this choice intuitively. Additionally, loss averse participants often showed an intuitive sensitivity to expected value (as reflected in decreased confidence). Overall, these results suggest that deliberation is not the primary route for expected-value-based responding in risky decision making. Risky decisions may be better conceptualized as an interplay between different types of "fast" intuitions rather than between two different types of "fast" and "slow" thinking per se.

The causal relationship model of factors influencing COVID-19 preventive behaviors during the post-pandemic era and implications for health prevention strategies: a case of Bangkok City, Thailand

BACKGROUND

Though, many countries are currently in the COVID post-pandemic era, people's health protective behaviours are still essential to protect their health and well-being. This study aims to evaluate people's understanding and perceptions of COVID-19 risk characteristics (i.e. threat occurrence, threat severity, perceived susceptibility and exposure), the health risk perception towards COVID-19, and health protective behaviours. The study also aims to estimate the associations among these factors by the analysis of structural equation modelling (SEM).

METHODS

From 15 October to 9 November 2022, questionnaire surveys were administrated to 521 people living in Bangkok of Thailand by using the convenience sampling technique. The analyses were carried out in three phases including descriptive statistical analyses, a measurement model assessment using a confirmatory factor analysis (CFA), and structural equation modelling (SEM) analysis.

RESULTS

The results of descriptive analyses demonstrated that the majority of respondents, 39.9%, had the age between 20 and 30 years old, and 61.4% of them were female. Approximately 52.1% of them had a bachelor's degree. Upon analysing individuals' understanding and perceptions of all risk characteristics, individuals' understanding of COVID-19 severity did not statistically affect health risk perception towards COVID-19, whereas perceived exposure had the strongest effect and in turn influenced health protective behaviours. Perceived susceptibility and understanding of the threat occurrence also significantly affected health risk perception, and indirectly affected health protective behaviours.

CONCLUSIONS

This study implies that though the potential health impact of COVID-19 is perceived as less severe, people can still construct a perception of its risk particularly based on their perceived exposure and susceptibility. Thus, communicating people about exposure conditions and susceptibility can greatly contribute to people' construction of risk perception towards COVID-19 which subsequently leads to the decision to perform health protective behaviours.

The 8 billion milestone: Risk perceptions of global population growth among UK and US residents

In November 2022, the global human population reached 8 billion and is projected to reach 10 billion by 2060. Theories, models, and evidence indicate that global population growth (GPG) increases the likelihood of many adverse outcomes, such as biodiversity loss, climate change, mass migrations, wars, and resource shortages. A small body of research indicates that many individuals are concerned about the effects of GPG, and these concerns are strongly related to the willingness to engage in mitigative and preventative actions. However, scientific understanding of the factors that influence GPG risk perceptions remains limited. To help address this research gap, we conducted a study of the perceived risk of GPG among UK and US residents (N = 1029) shortly after the "8 billion milestone." Our results confirmed that GPG is perceived as a moderate-to-high risk and these perceptions have a strong positive relationship with the willingness to engage in and support risk management actions. Our participants believed that the worst effects of GPG were yet to come but would largely be geographically and socially remote. Despite their willingness to engage in risk management actions, our participants reported low self-efficacy and that governments (cf. individuals and communities) have the greatest capacity to influence GPG. Risk perceptions were strongly predicted by worldviews and were higher among our UK (cf. US) participants. We also found that the perceived benefits of GPG were low and found no evidence to suggest that risk perceptions were affected by exposure to media coverage of the 8 billion milestone.

The hallmarks of a tradeoff in transcriptomes that balances stress and growth functions

Fast growth phenotypes are achieved through optimal transcriptomic allocation, in which cells must balance tradeoffs in resource allocation between diverse functions. One such balance between stress readiness and unbridled growth in E. coli has been termed the fear versus greed (f/g) tradeoff. Two specific RNA polymerase (RNAP) mutations observed in adaptation to fast growth have been previously shown to affect the f/g tradeoff, suggesting that genetic adaptations may be primed to control f/g resource allocation. Here, we conduct a greatly expanded study of the genetic control of the f/g tradeoff across diverse conditions. We introduced 12 RNA polymerase (RNAP) mutations commonly acquired during adaptive laboratory evolution (ALE) and obtained expression profiles of each. We found that these single RNAP mutation strains resulted in large shifts in the f/g tradeoff primarily in the RpoS regulon and ribosomal genes, likely through modifying RNAP-DNA interactions. Two of these mutations additionally caused condition-specific transcriptional adaptations. While this tradeoff was previously characterized by the RpoS regulon and ribosomal expression, we find that the GAD regulon plays an important role in stress readiness and ppGpp in translation activity, expanding the scope of the tradeoff. A phylogenetic analysis found the greed-related genes of the tradeoff present in numerous bacterial species. The results suggest that the f/g tradeoff represents a general principle of transcriptome allocation in bacteria where small genetic changes can result in large phenotypic adaptations to growth conditions.IMPORTANCETo increase growth, E. coli must raise ribosomal content at the expense of non-growth functions. Previous studies have linked RNAP mutations to this transcriptional shift and increased growth but were focused on only two mutations found in the protein's central region. RNAP mutations, however, commonly occur over a large structural range. To explore RNAP mutations' impact, we have introduced 12 RNAP mutations found in laboratory evolution experiments and obtained expression profiles of each. The mutations nearly universally increased growth rates by adjusting said tradeoff away from non-growth functions. In addition to this shift, a few caused condition-specific adaptations. We explored the prevalence of this tradeoff across phylogeny and found it to be a widespread and conserved trend among bacteria.

Emotional and Cognitive "Route" in Decision-Making Process: The Relationship between Executive Functions, Psychophysiological Correlates, Decisional Styles, and Personality

Studies on decision-making have classically focused exclusively on its cognitive component. Recent research has shown that a further essential component of decisional processes is the emotional one. Indeed, the emotional route in decision-making plays a crucial role, especially in situations characterized by ambiguity, uncertainty, and risk. Despite that, individual differences concerning such components and their associations with individual traits, decisional styles, and psychophysiological profiles are still understudied. This pilot study aimed at investigating the relationship between individual propensity toward using an emotional or cognitive information-processing route in decision-making, EEG and autonomic correlates of the decisional performance as collected via wearable non-invasive devices, and individual personality and decisional traits. Participants completed a novel task based on realistic decisional scenarios while their physiological activity (EEG and autonomic indices) was monitored. Self-report questionnaires were used to collect data on personality traits, individual differences, and decisional styles. Data analyses highlighted two main findings. Firstly, different personality traits and decisional styles showed significant and specific correlations, with an individual propensity toward either emotional or cognitive information processing for decision-making. Secondly, task-related EEG and autonomic measures presented a specific and distinct correlation pattern with different decisional styles, maximization traits, and personality traits, suggesting different latent profiles.

Risk-Adapted Breast Screening for Women at Low Predicted Risk of Breast Cancer: An Online Discrete Choice Experiment

BACKGROUND

A risk-stratified breast screening program could offer low-risk women less screening than is currently offered by the National Health Service. The acceptability of this approach may be enhanced if it corresponds to UK women's screening preferences and values.

OBJECTIVES

To elicit and quantify preferences for low-risk screening options.

METHODS

Women aged 40 to 70 y with no history of breast cancer took part in an online discrete choice experiment. We generated 32 hypothetical low-risk screening programs defined by 5 attributes (start age, end age, screening interval, risk of dying from breast cancer, and risk of overdiagnosis), the levels of which were systematically varied between the programs. Respondents were presented with 8 choice sets and asked to choose between 2 screening alternatives or no screening. Preference data were analyzed using conditional logit regression models. The relative importance of attributes and the mean predicted probability of choosing each program were estimated.

RESULTS

Participants (N = 502) preferred all screening programs over no screening. An older starting age of screening, younger end age of screening, longer intervals between screening, and increased risk of dying had a negative impact on support for screening programs (P < 0.01). Although the risk of overdiagnosis was of low relative importance, a decreased risk of this harm had a small positive impact on screening choices. The mean predicted probabilities that risk-adapted screening programs would be supported relative to current guidelines were low (range, 0.18 to 0.52).

CONCLUSIONS

A deintensified screening pathway for women at low risk of breast cancer, especially one that recommends a later screening start age, would run counter to women's breast screening preferences. Further research is needed to enhance the acceptability of offering less screening to those at low risk of breast cancer.

HIGHLIGHTS

Risk-based breast screening may involve the deintensification of screening for women at low risk of breast cancer.Low-risk screening pathways run counter to women's screening preferences and values.Longer screening intervals may be preferable to a later start age.Work is needed to enhance the acceptability of a low-risk screening pathway.

Assessing the Pragmatic Effectiveness and Implementation of Click City: Tobacco: A School-Based Prevention Program Targeting Youth Cigarette and E-cigarette Use

INTRODUCTION

Given the rapid increase in the prevalence of e-cigarette use among youth, we updated Click City: Tobacco, an existing, efficacious, online tobacco prevention program for 5th graders with a 6th-grade booster, to also target e-cigarette use.

METHODS

To evaluate the effectiveness of the updated 5th-grade program within a "real world" setting, we conducted a pragmatic randomized trial with 5th-grade students in 43 schools across Arizona and Oregon, assessing change in intentions and willingness to use e-cigarettes/cigarettes, from baseline to one-week post-intervention. Students in intervention schools (n = 1327) received the updated version of Click City: Tobacco; students in control schools (n = 1346) received their usual tobacco prevention curriculum.

RESULTS

Students in intervention schools significantly decreased their intentions and willingness to use e-cigarettes and cigarettes, compared to students in control schools. The intervention also significantly changed all targeted etiological mechanisms predictive of intentions and willingness. The intervention was more effective for at-risk students, as defined by student's previous tobacco use, current family use of tobacco, and/or high in sensation-seeking. The effects of the intervention on all outcomes were similar as a function of state, gender, ethnicity, and historical timing (before COVID-19 pandemic school closures vs. after schools re-opened). Close to 90% of the students in the intervention condition completed the entire program, supporting fidelity of implementation, and teachers reported satisfaction with the program.

CONCLUSIONS

Findings suggest that Click City: Tobacco is effective for all 5th-grade students and can be delivered with fidelity across school settings.

IMPLICATIONS

The results of a randomized pragmatic effectiveness trial showed that the updated Click City: Tobacco program decreased intentions and willingness to both vape e-cigarettes and smoke cigarettes among 5th-grade students, particularly for those at high risk. Program effectiveness and lack of differences because of factors such as state, gender, ethnicity, and historical timing have universal implications, suggesting that all students can benefit from this program. Click City: Tobacco received high ratings of program satisfaction from teachers and was implemented with fidelity. Findings suggest that Click City: Tobacco is effective and can be easily implemented in schools.

Can major public health emergencies increase the participation of commercial insurance? Evidence from China

Background

Public health emergencies have a lasting impact on a country's economic and social development. However, commercial insurance can disperse these negative consequences and reduce risk losses.

Method

Based on the Chinese Household Tracking Survey and Peking University Digital Inclusive Finance Index, this study employed a difference-in-differences model to test the impact of the COVID-19 outbreak on commercial insurance participation and the impact mechanism.

Results

The analysis showed that the outbreak of COVID-19 improved residents' risk perception, risk preference and digital finance and promoted their participation in commercial insurance, commercial endowment insurance, and commercial medical insurance.

Conclusion

Major public health emergencies can increase commercial insurance participation, but the promotional effect of commercial insurance on rural and low-income individuals is relatively limited. To tap into potential customers, financial institutions should focus on vulnerable societal groups. This study supplements the relevant literature on the impact of major public health emergencies on commercial insurance participation.

Consumers' perception of novel foods and the impact of heuristics and biases: A systematic review

According to the definition adopted in the European Union, novel foods are foods that were not consumed to a significant degree within the Union before May 15, 1997. This includes cultivated meat and insects. Novel foods are meant to play a critical role in the transition towards sustainable food systems. However, their success depends on whether and to what extent they will be incorporated into the diets at the population level. This review investigates consumers' perception of novel food products by narratively synthesising results on the influence of heuristics and biases triggered by emotions, personality traits, and socio-cultural factors. Empirical studies conducted in Western countries and published in English after 1997 were eligible, which led to 182 studies being included. Notably, most included studies focused on insects and cultivated meat. Disgust and fear are shown to be the main emotions driving rejection of novel foods, together with food neophobia and specific cultural norms common across countries included in the scope of the review. Familiarity with novel foods and curiosity both led to higher acceptance. Despite being investigated directly in a minority of studies, heuristics and related biases mostly fell under the "affect," the "natural-is-better," and the "trust" heuristics. The review also discusses to what extent consumers' perception reflects in the regulatory framework applicable to novel foods in the European Union, how it influences the regulation of insects and cultivated meat and which lessons can be drawn for the future of the regulatory framework.

An assessment of nurses' perceived and actual household emergency preparedness

Nurses' household preparedness is critical if they are to avoid role conflict and report for duty during an emergency. To date, the alignment between nurses' perceived and actual household preparedness remains under examined. Investigating one of these variables in isolation fails to consider that perceived and actual household preparedness must be high and aligned. If misaligned, vulnerabilities could surface during emergencies, like concerns about family safety, potentially impacting a nurse's commitment to duty during a crisis, or nurses may lack the actual preparedness to continue working long hours during an emergency. An online questionnaire was distributed to registered nurses in Ireland. The questionnaire was informed by a review of the literature and captured nurses' perceived and actual household preparedness, attitudes towards and exposure to a range of emergencies, and pertinent demographic characteristics. The results showed a relationship between how nurses view their household preparedness and their actual preparedness. Regression analyses indicate that while there is an overlap, the factors associated with how prepared nurses think they are and how prepared they are can differ. This means that strategies to boost actual preparedness may differ from those needed to boost perceived preparedness. This finding underscores the importance of psychosocial preparedness. Feeling prepared is crucial as it can influence how one responds in an emergency. Considering both the perceived and actual aspects of household preparedness can lead to a more effective response during emergencies.

Impact of risk perception and disease cognition on the willingness to participate in screening for lung cancer in a high-risk population

OBJECTIVE

Risk perception and disease cognition may influence the efficiency of lung cancer screening by affecting the participation rate. There is still some uncertainty regarding the association between risk perception and disease cognition and how they affect participation in lung cancer screening. Therefore, we explored the influence of risk perception and disease cognition on the willingness to participate in screening among people at high risk of lung cancer.

METHODS

Subjects with high-risk factors for lung cancer were recruited in Lu'an City, Anhui Province, China. Questionnaires were used to determine their demographic characteristics, risk perception, disease cognition, and willingness to engage in screening.

RESULTS

Of the 1955 subjects with high risk factors for lung cancer, 1136 (58.12%) were willing to participate in lung cancer screening. Univariable and multivariable analyses showed that disease cognition ( adj OR = 2.012, 95% CI: 1.528-2.649, P  = 0.000), cognitive risk ( adj OR = 7.661, 95% CI: 6.049-9.704, P  = 0.000), and affective risk ( adj OR = 5.964, 95% CI: 4.552-7.815, P  = 0.000) were significant factors in promoting screening participation. For those with moderate risk perception, improving disease cognition was a key approach to increase screening participation.

CONCLUSION

This study elucidated the relationship between various factors and lung cancer screening participation and proposed a feasible route for the screening implementation, providing a theoretical basis to further improve the participation rate and efficiency of lung cancer screening.

Perceptions of COVID-19 Risk: How Did People Adapt to the Novel Risk?

BACKGROUND

There is limited understanding of how risk perceptions changed as the US population gained experience with COVID-19. The objectives were to examine risk perceptions and determine the factors associated with risk perceptions and how these changed over the first 18 mo of the pandemic.

METHODS

Seven cross-sectional online surveys were fielded between May 2020 and October 2021. The study included a population-weighted sample of 138,303 US adults drawn from a market research platform, with an average 68% cooperation rate. Respondents' risk perception of developing COVID in the next 30 days was assessed at each time point. We examined relationships between 30-day risk perceptions and various factors (including sociodemographic features, health, COVID-19 experience, political affiliation, and psychological variables).

RESULTS

COVID risk perceptions were stable across the 2020 surveys and showed a significant decrease in the 2021 surveys. Several factors, including older age, worse health, high COVID worry, in-person employment type, higher income, Democratic political party affiliation (the relatively more liberal party in the United States), low tolerance of uncertainty, and high anxiety were strongly associated with higher 30-d risk perceptions in 2020. One notable change occurred in 2021, in that younger adults (aged 18-29 y) had significantly higher 30-d risk perceptions than older adults did (aged 65 y and older) after vaccination. Initial differences in perception by political party attenuated over time. Higher 30-d risk perceptions were significantly associated with engaging in preventive behaviors.

LIMITATIONS

Cross-sectional samples, risk perception item focused on incidence not severity.

CONCLUSIONS

COVID risk perceptions decreased over time. Understanding the longitudinal pattern of risk perceptions and the factors associated with 30-d risk perceptions over time provides valuable insights to guide public health communication campaigns.

HIGHLIGHTS

The study assessed COVID-19 risk perceptions at 7 time points over 18 mo of the pandemic in large samples of US adults.Risk perceptions were fairly stable until the introduction of vaccines in early 2021, at which point they showed a marked reduction.Higher COVID-19 30-d risk perceptions were significantly associated with the preventive behaviors of masking, limiting social contact, avoiding restaurants, and not entertaining visitors at home.

Shifting Perceptions and Emotional Responses to Autonomous Vehicles Using Simulated Experiences

The societal integration of autonomous vehicles (AVs) relies on public acceptance, closely related to individual emotions and perceptions. This study explores the emotional factors affecting AV acceptance in Spain through lexical tasks, virtual AV simulations, and questionnaires, surpassing traditional attitude surveys by examining subtle emotional and lexical reactions to AVs. Acceptance was measured in terms of AV knowledge, perception of autonomous driving, and safety, with emphasis on lexical-emotional analysis after simulation. Findings indicate gender differences in AV acceptance, with women showing less knowledge and comfort with AV technology. Simulation improved understanding and generated more positive responses. This study shows how lexical tasks can reveal emotional influences on AV perception and suggests a wider approach to assess technology acceptance. These findings aid in creating campaigns and experiences to enhance public AV acceptance, mindful of demographic differences. Future studies should extend this framework to various populations to investigate the emotional lexicon's role in AV acceptance.

Associations between smokers' knowledge of causes of smoking harm and related beliefs and behaviors: Findings from the International Tobacco Control (ITC) Four Country Smoking and Vaping Survey

BACKGROUND

Most smokers know that smoking is harmful to health, but less is known about their understanding of what causes the harms. The primary aim was to examine smokers' perceptions of the relative contributions to smoking-related morbidity from combustion products, nicotine, other substances present in unburned tobacco, and additives. A secondary aim was to evaluate the association of these perceptions with nicotine vaping product use intentions, and quitting motivation/intentions.

METHODS

Participants were current smokers and recent ex-smokers from Australia, Canada, England and the United States (N = 12,904, including 8511 daily smokers), surveyed in the 2018 International Tobacco Control Four Country Smoking and Vaping Survey. Respondents reported on how much they thought combustion products, nicotine, chemicals in the tobacco and additives in cigarettes contribute to smoking-related morbidity (none/very little; some but less than half; around half; more than half; all or nearly all of it; don't know).

RESULTS

Overall, 4% of participants provided estimates for all four component causes that fell within the ranges classified correct, with younger respondents and those from England most likely to be correct. Respondents who rated combustion as clearly more important than nicotine in causing harm (25%) were the least likely to be smoking daily and more likely to have quit and/or to be vaping. Among daily smokers, all four cause estimates were independently related to overall health worry and extent of wanting to quit, but the relative rating of combustion compared to nicotine did not add to prediction. Those who answered 'don't know' to the sources of harm questions and those suggesting very little harm were consistently least interested in quitting.

CONCLUSIONS

Most smokers' knowledge of specific causes of harm is currently inadequate and could impact their informed decision-making ability.

Understanding the Process of Family Cancer History Collection and Health Information Seeking

PROBLEM ADDRESSED

To better understand the factors associated with family cancer history (FCH) information and cancer information seeking, we model the process an individual undergoes when assessing whether to gather FCH and seek cancer information and compare models by sociodemographics and family history of cancer. We used cross-sectional data from the Health Information National Trends Survey (HINTS 5, Cycle 2) and variables (e.g., emotion and self-efficacy) associated with the Theory of Motivated Information Management to assess the process of FCH gathering and information seeking. We completed path analysis to assess the process of FCH gathering and stratified path models.

RESULTS

Those who felt they could lower their chances of getting cancer (emotion) were more confident in their ability to complete FCH on a medical form (self-efficacy; B = 0.11, p < .0001) and more likely to have discussed FCH with family members (B = 0.07, p < .0001). Those who were more confident in their ability to complete a summary of their family history on a medical form were more likely to have discussed FCH with family members (B = 0.34, p < .0001) and seek other health information (B = 0.24, p < .0001). Stratified models showed differences in this process by age, race/ethnicity, and family history of cancer.

IMPLICATIONS FOR PUBLIC HEALTH RESEARCH AND PRACTICE

Tailoring outreach and education strategies to address differences in perceived ability to lower chances of getting cancer (emotion) and confidence in the ability to complete FCH (self-efficacy) could help encourage less engaged individuals to learn about their FCH and gather cancer information.

Evolutionary game analysis of indoor radon mitigation with local government involvement

Radon is the second leading risk factor for lung cancer after smoking. As a public policy, radon mitigation not only involves radon control technology or its cost-benefit analysis, but also includes the decision-making process of local governments. In this study, the evolutionary game theory was used to analyse the interaction between local governments and residents based on the subsidy of the central government. Considering the practical data in China, factors influencing the behaviour of local governments and residents were discussed using numerical simulations. The results indicated that radon mitigation is a fully government-promoted action; thus, its implementation largely depends on the subsidy of the central government and the share of radon control costs borne by the local government. The financial burden for both local governments and residents is a more important determinant than long-term health effects. The relatively poor local economic situation could limit the implementation of radon control. There would be a public policy paradox wherein cities or regions with higher radon risk would have lower willingness for radon control, mainly due to the significantly higher costs of radon control. This work provides reference data for decision-making to implement radon control and is expected to offer some suggestions for local governments.

Visualizing risky situations induces a stronger neural response in brain areas associated with mental imagery and emotions than visualizing non-risky situations

In an fMRI study, we tested the prediction that visualizing risky situations induces a stronger neural response in brain areas associated with mental imagery and emotions than visualizing non-risky and more positive situations. We assumed that processing mental images that allow for "trying-out" the future has greater adaptive importance for risky than non-risky situations, because the former can generate severe negative outcomes. We identified several brain regions that were activated when participants produced images of risky situations and these regions overlap with brain areas engaged in visual, speech, and movement imagery. We also found that producing images of risky situations, in contrast to non-risky situations, was associated with increased neural activation in the insular cortex and cerebellum-the regions involved, among other functions, in emotional processing. Finally, we observed an increased BOLD signal in the cingulate gyrus associated with reward-based decision making and monitoring of decision outcomes. In summary, risky situations increased neural activation in brain areas involved in mental imagery, emotional processing, and decision making. These findings imply that the evaluation of everyday risky situations may be driven by emotional responses that result from mental imagery.

Psychological distress in three Australian communities living with environmental per- and polyfluoroalkyl substances contamination

BACKGROUND

Environmental chemical contamination is a recognised risk factor for psychological distress, but has been seldom studied in the context of per- and polyfluoroalkyl substances (PFAS) contamination. We examined psychological distress in a cross-sectional study of three Australian communities exposed to PFAS from the historical use of aqueous film-forming foam in firefighting activities, and three comparison communities without environmental contamination.

METHODS

Participation was voluntary following recruitment from a PFAS blood-testing program (exposed) or random selection (comparison). Participants provided blood samples and completed a survey on their exposure history, sociodemographic characteristics, and four measures of psychological distress (Kessler-6, Distress Questionnaire-5, Patient Health Questionnaire-15, and Generalised Anxiety Disorder-7). We estimated prevalence ratios (PR) of clinically-significant psychological distress scores, and differences in mean scores: (1) between exposed and comparison communities; (2) per doubling in PFAS serum concentrations in exposed communities; (3) for factors that affect the perceived risk of living in a community exposed to PFAS; and (4) in relation to self-reported health concerns.

RESULTS

We recruited 881 adults in exposed communities and 801 in comparison communities. We observed higher levels of self-reported psychological distress in exposed communities than in comparison communities (e.g., Katherine compared to Alice Springs, Northern Territory: clinically-significant anxiety scores, adjusted PR = 2.82, 95 % CI 1.16-6.89). We found little evidence to suggest that psychological distress was associated with PFAS serum concentrations (e.g., Katherine, PFOS and anxiety, adjusted PR = 0.85, 95 % CI 0.65-1.10). Psychological distress was higher among exposed participants who were occupationally exposed to firefighting foam, used bore water on their properties, or were concerned about their health.

CONCLUSION

Psychological distress was substantially more prevalent in exposed communities than in comparison communities. Our findings suggest that the perception of risks to health, rather than PFAS exposure, contribute to psychological distress in communities with PFAS contamination.

The impact of influences in a medical screening programme invitation: a randomized controlled trial

BACKGROUND

Invitations to screening programmes may include influences that are intending to increase the participation rates. This study had two objectives: (i) to assess if different categories of influences had a significant effect on the intention to participate in a screening programme for a fictitious disease and (ii) whether participants were aware of the influences, and if the intention to participate was associated to this awareness.

METHODS

A seven-armed randomized controlled trial. Six hundred passers-by were randomly allocated to receive one of seven pamphlets inviting to a fictitious screening programme (neutral, relative risk reductions, misrepresentation of harms, pre-booked appointment, recommendation of participation, fear appeals, all combined). Participants were surveyed to assess (i) intention to participate (ITP) in the screening programme and (ii) awareness of an exerted influence. Chi-squared test was used to calculate the effect of the influences on ITP and the association of ITP with indicating awareness of an exerted influence and correctly locating an influence.

RESULTS

Five hundred and eighty-nine participants were included for analysis. ITP was significantly increased (P < 0.05) in three pamphlets (misrepresentation of harms, fear appeals, all combined) [adjusted odds ratio (OR) 4.84, 95% confidence interval (CI): 2.54-9.23; OR 2.45, 95% CI: 1.31-4.59; OR 9.02, 95% CI: 4.44-18.34]. A percentage of 60.0-78.3 participants did not indicate awareness. Awareness was associated with a decreased ITP for those who could locate the influence (OR 0.39, 95% CI: 0.21-0.72) and those who failed to locate the influence (OR 0.47, 95% CI: 0.30-0.74).

CONCLUSION

The application of influences should be carefully considered for interventions where an informed choice is desired.

Emotion, Aging, and Decision Making: A State of the Art Mini-Review

Over the past few decades, interest has begun to surge in understanding the role of emotion in decision making, and more recently in studies across the adult life span. Relevant to age-related changes in decision making, theoretical perspectives in judgment and decision making draw critical distinctions between deliberative versus intuitive/affective processes, as well as integral versus incidental affect. Empirical findings demonstrate the central role of affect in various decision-related domains such as framing and risk taking. To situate this review within an adult life-span context, we focus on theoretical perspectives in adult development regarding emotion and motivation. As a result of age differences in deliberative and emotional processes, taking a life-span perspective is critical to advance a comprehensive and grounded understanding of the role of affect in decision making. Age-related shifts in information processing from negative toward positive material also have consequential implications. By taking a life-span perspective, not only will decision theorists and researchers benefit, but so too will practitioners who encounter individuals of various ages as they make consequential decisions.

Effects of emotional congruency and task complexity on decision-making

The heuristic approach to decision-making holds that the selection process becomes more efficient when part of the information available is ignored. One element involved in selecting information is emotional valence. If emotional congruency is related to simplified decision-making strategies, then the interaction of this factor with task complexity should exist. The present study explored how factors of this nature influence decision-making efficiency. We hypothesized that emotional congruency would have a positive effect on task execution and that the magnitude of that effect would increase with greater task complexity because in that condition the amount of information to be processed is greater, meaning that a heuristic approach to the problem would be more efficient. We design a decision in browser decision-making task in which participants had to select emotional images to gain points. Depending on the correlation between emotional valence and in-task image value, we defined three emotional congruency conditions: direct, null, and inverse. Our results show that distinct types of emotional congruency have differential effects on behavior. While direct congruency-enhanced overall decision-making performance, inverse congruency interacted with task complexity to modify the pace at which task feedback affected behavior.

The effect of emotion regulation strategies on decision-making about the maternal pertussis vaccination among pregnant women in the Netherlands: an experimental study

OBJECTIVE

To assess whether cognitive reappraisal and acceptance are effective emotion regulation strategies to decrease the influence of negative affect on intention to accept maternal pertussis vaccination (MPV) among pregnant women in the Netherlands.

METHODS

An experimental study with baseline and two follow-up measurements was conducted. Participants selected after baseline (N = 382) were randomized into two experimental groups (cognitive reappraisal, acceptance) and a control group. The effect of the experimental manipulations on negative affect was examined with multilevel analyses. A moderation analysis was performed to examine whether the manipulations moderated the association between negative affect and intention.

RESULTS

All groups showed a decrease in negative affect (all p's < 0.001), with no differences between groups. A small decrease in the influence of negative affect on intention was found among those who used acceptance.

CONCLUSION

No additional value of the emotion regulation strategies was found compared to the control group. However, exploratory analyses showed that acceptance seemed a promising strategy to decrease the influence of negative affect on intention to accept MPV.

PRACTICE IMPLICATIONS

This study stressed the relevance for communication strategies to consider the emotions pregnant women experience during the decision-making process about the MPV.

Worldview Orientations and Personal and Social Risk Perceptions for COVID-19 in a U.S. Population-Based Sample

Adoption of COVID-19 preventive behaviors involves considering personal risk and the risk to others. Consequently, many COVID-19 prevention measures are intended to protect both the individual engaging in the behavior and others in the population. Yet, the preponderance of research is focused on perceptions of an individual's personal risk, making risk perception for others a critical area for investigation. Two worldview orientations describing values regarding how society should be organized, hierarchy-beliefs prioritizing social hierarchy, and individualism-beliefs prioritizing personal autonomy, have been linked to a range of risk perceptions. This study objective is to examine the association of worldview orientations with COVID-19 risk perceptions for oneself and others in a United States context. Using a national sample of 410 U.S. adults, we examined the associations between worldview orientations and six facets of risk (absolute risk, risk certainty, comparative risk, risk severity, fear, feelings of risk) using demographics-adjusted multivariable regression models. We conducted separate analyses for each of the following referents: (1) personal risk, (2) risk for the average person within the United States, and (3) risk to people within specific social groups (e.g., family, co-workers). Results indicate that stronger hierarchical and individualistic orientations were associated with lower COVID-19 risk perceptions for all three referents. The results were particularly consistent for fear and feelings of risk. Individualism was related to higher risk perception certainty for personal risk and the risk to people within specific social groups. Hierarchy was related to lower perceived severity for all referents. Findings suggest that U.S. public health messaging sensitive to worldview orientations may be needed to optimize acceptance of recommendations for protective behaviors, including vaccination. The relationship of worldview orientations to health risk perceptions may help guide messaging for future infectious outbreaks where risk perceptions are t drivers of protective behavior.

"We don't have the same bodies; we don't react the same way": mothers and adolescent girls' perceptions of the risks and benefits of HPV vaccination in France

Human Papillomavirus (HPV) vaccination is one of the most publicly mistrusted vaccines in Europe, with countries such as France struggling with low vaccine uptake due to parental questioning of vaccine risks and benefits. However, limited evidence exists on adolescent girls' perceptions of the risks and benefits of HPV vaccination. The aim of this qualitative study was to provide an in-depth exploration and comparison of French mothers (n = 21) and adolescent girls' (n = 36) perceptions of the risks and benefits of HPV vaccination. A thematic analysis showed that adolescent girls and mothers perceived the risks and benefits of HPV vaccination differently, with girls reporting positive and beneficial views and emotions toward vaccination and mothers expressing concerns about possible risks. Adolescent girls also reported that both perceptions and actual risks and benefits may vary from one individual to another. Vaccine safety was also understood differently, with mothers reporting a widespread view that vaccines are unsafe and focusing on controversial side effects and girls discussing short-term consequences of vaccination (e.g. pain, fever) and administration and storage issues. Strategies to improve uptake of HPV vaccination should consider and address both the mothers' and daughters' perceptions and understandings of HPV vaccination.

Modeling the occupational health risk of workers caused by environmental release during the production of PC components

Prefabricated construction is one of the solutions to the problem of balancing environmental improvements with the new buildings in the construction industry. Some work originally done on site is transferred to the front end, and the occupational health risks to industrial workers during the production of prefabricate concrete components are thus aggravated. This study aims to propose a framework to simulate the occupational health risks of workers in prefabricate concrete component plants from the perspective of risk identification, risk assessment, and risk control. Through the following 4 steps, including environmental release monitoring, diffusion and human inhalation mechanism analysis, occupational health risk evaluation, and full-path health risk simulation, this study maps physical entities to virtual reality. The proposed method tends to address the root causes behind occupational health risks, such as the lack of measurement, assessment and prevention criteria, and providing new ideas for theoretical research and innovative practice of HSE management and risk management in the construction industry.

Shared understandings of vaccine hesitancy: How perceived risk and trust in vaccination frame individuals' vaccine acceptance

Extensive research has framed vaccine hesitancy as a property of a heterogeneous group of individuals, ranging from total acceptance to complete refusal. Nevertheless, not much research has explored this heterogeneity, mainly focusing on central tendencies of single belief-related items. Using data from an original survey on a sample of Italian citizens, this paper examines this heterogeneity, exploiting individuals' cognitive variation to map clusters of individuals who share similar cognitive schemas on vaccine uptake. The results showed the existence three groups, characterized by a different articulation of predictors of vaccine hesitancy, revealing different understandings of vaccine uptake. We then analyzed within-cluster characteristics and showed that cognitive segmentation was connected to different levels of perceived risk, confidence, and support for vaccination. We further showed that cognitive clustering also entailed a mean of social stratification that was correlated with individuals' educational levels, and that the predictors of vaccine hesitancy were articulated differently in each group. This study, adopting a recent perspective in the analysis of systems of beliefs, moves one step further in disentangling the complexity of vaccine acceptance. Results suggested the usefulness of including individuals' cognitive characteristics in vaccine hesitancy research and in the development of interventions addressed at increasing vaccine acceptance.

Travel despite the COVID-19 pandemic: Implications for tourism recovery

The COVID-19 pandemic has devastated the global tourism industry. This study explores why some Chinese residents travel during the pandemic. A mixed-methods research design was adopted, guided by the health belief model and relevant literature. Through 21 interviews with Chinese tourists who took an overnight leisure trip in May 2020, and a national survey among Chinese residents, this study explored factors influencing Chinese residents' travel-related decisions and behaviors during the pandemic. Results outline the influences of health beliefs, government trust, past travel experience, and psychological capital on tourists' risk-reduction behaviors. Theoretical and practical implications are provided regarding tourism recovery during pandemics.

Parental Assessment of Benefits and of Dangers Determines Children's Permission to Play Outdoors

During the early years, children's outdoor play is dependent on parental supervision. Parents' perceptions are likely to influence what the child is permitted to do. To better understand the involved mechanisms in parents' decision making in such contexts, an online photo-based questionnaire was administered. The tool investigates, in different situations, parents and their children's experience, parents' perceptions, and permission to play. A total of 417 parents of children aged from 1.5 and 6.0 completed the questionnaire. Results showed that parents, overall, have a positive attitude towards outdoor play. Main concerns were about risk of injury but in most cases, perceived benefits outweigh perceived dangers. "Sawing wood" was the only situation with a negative benefits/dangers balance. A linear regression analysis revealed that permission to play outdoors is based on parental assessment of benefits and dangers. Perceived benefits appeared to have more influence on parental decision than perceived dangers, while perceived competence had only a small influence. The results also showed that parents' childhood experience of outdoor play was an important determinant for adults' perceptions, perhaps demonstrating intergenerational concerns, as outdoor play is in decline. To overcome a negative intergenerational effect on children's outdoor play, interventions and communication should focus on associated benefits.

Personality traits and behaviour biases: the moderating role of risk-tolerance

The current research tries to contribute to the prospect theory by examining how personality factors affect behaviour biases. Moreover, the study tries to inspect how risk-tolerance behaviour moderates the relationship between personality traits and behavior biases. The research considered a cross-sectional research design to collect responses from 847 individual investors through a questionnaire. The study considered a convenience sampling technique. Further to examine the hypotheses, the study used SEM and PROCESS macro v3.0 for SPSS. The findings of the study suggest that conscientiousness and extroversion traits significantly influence behaviour biases. The findings also explain that neuroticism was associated with herding, disposition, and anchoring bias. The findings confirmed the moderating effect of risk-tolerance on the association between personality traits and behaviour biases. The findings contribute to the existing literature of behaviour finance by focusing on the prospect theory as well as some practical implications for investors and financial advisors. The study suggests to the individual investors with different traits how they can overcome these biases while investing. The study suggests that financial advisors should educate their clients and also establish a lock-gain point and stop-loss point to reduce the effect of such biases. The study also suggests that investment advisors should provide information more efficiently so that investors' portfolios could be amassed into a well-diversified investment and tries to set up efficient approaches associated with investment quality and give swapping options as per their risk-tolerance behavior. The research contributes to behaviour finance literature by signifying the moderation effect of risk tolerance on the association amid personality factors and behavioural biases and how it reduces the influence of biases while taking investment decisions among Indian investors. To the best of our knowledge, this is the first comprehensive study that examines the moderation effect of risk-tolerance among the relationship between personality traits and behaviour biases. Furthermore, it demonstrates that an individual's risk-tolerance enhances their involvement in the decision-making process, allowing them to make the best financial option possible.

Common and Distinct Neural Correlates of Intertemporal and Risky Decision-Making: Meta-Analytical Evidence for the Dual-System Theory

The relationship between intertemporal and risky decision-making has received considerable attention in decision research. Single-process theories suggest that choices involving delay and risk are simply two manifestations of the same psychological mechanism, which implies similar patterns of neural activation. Conversely, the dual-system theory suggests that delayed and risky choices are two contrasting types of processes, which implies distinct brain networks. How these two types of choices relate to each other remains unclear. The current study addressed this issue by performing a meta-analysis of 28 intertemporal decision-making studies (862 subjects) and 51 risky decision-making studies (1539 subjects). We found no common area activated in the conjunction analysis of the delayed and risky rewards. Based on the contrast analysis, delayed rewards were associated with stronger activation in the left dorsal insula, while risky rewards were associated with activation in the bilateral ventral striatum and the right anterior insula. The results align with the dual-system theory with separate neural networks for delayed and risky rewards.

Risk perception, but also political orientation, modulate behavioral response to COVID-19: A randomized survey experiment

Prior work has shown that accurately perceiving the risk for COVID-19 is associated with higher adherence to protective health behaviors, like face mask use, and more acceptance of governmental restrictive measures such as partial or complete banning of indoor activities and social gatherings. In this study we explored these associations at the beginning of the second wave of COVID-19 in Argentina through a national representative probabilistic survey that evaluated personal and contextual risk perception, self-reported compliance with protective health behaviors, attitude to governmental restrictive measures, and political orientation and psychological distress as potential modulators. Also, going beyond measures of association, here we sought to test whether messages highlighting potential risks increased acceptance of restrictive measures. Three types of messages were randomized to the participants. Two messages conveyed risk-related content (either through emotional arousal or cognitive appraisal) and the third a prosocial, altruistic content. Between March 29th and 30th, 2021, 2,894 participants were recruited (57.57% female). 74.64% of those surveyed evaluated the current health situation as “quite serious” or “very serious” and 62.03% estimated that the situation will be “worse” or “much worse” in the following 3 months. The perception of personal risk and the level of adherence to protective behaviors gradually increased with age. Through a regression model, age, perceived personal risk, and contextual risk appraisal were the variables most significantly associated with protective behaviors. In the case of the acceptance of restrictive measures, political orientation was the most associated variable. We then found messages aimed at increasing risk perception (both emotionally or cognitively focused) had a significantly greater effect on increasing the acceptance of restrictive measures than the prosocial message, mainly for government supporters but also for non-supporters. However, the level of response was also modulated by the political orientation of the participants. We propose a mechanism of “ideological anchoring” to explain that participants were responsive to risk modulation, but within the limits established by their pre-existent political views. We conclude that messages highlighting risk can help reinforce the acceptance of restrictive measures even in the presence of polarized views, but must be calibrated by age and political orientation.

Volunteers' concerns about facial neuromuscular electrical stimulation

Facial neuromuscular electrical stimulation (NMES) is the application of an electrical current to the skin to induce muscle contractions and has enormous potential for basic research and clinical intervention in psychology and neuroscience. Because the technique remains largely unknown, and the prospect of receiving electricity to the face can be daunting, willingness to receive facial NMES is likely to be low and gender differences might exist in the amount of concern for the sensation of pain and skin burns. We investigated these questions in 182 healthy participants. The likelihood of taking part (LOTP) in a hypothetical facial NMES study was measured both before and after presenting a detailed vignette about facial NMES including its risks. Results showed that LOTP was generally high and that participants remained more likely to participate than not to, despite a decrease in LOTP after the detailed vignette. LOTP was significantly predicted by participants' previous knowledge about electrical stimulation and their tendency not to worry about the sensations of pain, and it was inversely related to concerns for burns and loss of muscle control. Fear of pain was also inversely related to LOTP, but its effect was mediated by the other concerns. We conclude that willingness to receive facial NMES is generally high across individuals in the studied age range (18-45) and that it is particularly important to reassure participants about facial NMES safety regarding burns and loss of muscle control. The findings are relevant for scholars considering using facial NMES in the laboratory.

What catalyzes the proactive recovery of peasants from the COVID-19 pandemic? A livelihood perspective in Ningqiang County, China

The livelihood recovery strategy is utilized for peasants during the COVID-19 pandemic. This strategy serves a salient role to help them recover from the relevant hazardous impacts. Disaster risk has been a major concern among hazards for the increasing likelihood of exposure and vulnerability, especially in the process of poverty alleviation in China. However, few studies have discussed the factors and mechanisms that influence peasants to adopt livelihood recovery strategies in the context of the COVID-19 pandemic in China. Based on a case study of Ningqiang County, China, this study explores the mechanisms that catalyze the proactive recovery of peasants from the COVID-19 pandemic from a livelihood perspective. Methodologically, the study proposes a framework that integrates the modified pressure-state-response (PSR) framework and the sustainable livelihoods approach (SLA), and it employs structure equation modeling (SEM) approach to examine how specific factors affect peasants to proactively adopt livelihood strategies to recover from the COVID-19 pandemic. The results indicate that the COVID-19 pressure significantly increases the risk perception of peasants and decreases their livelihood capital. Further, the decreased livelihood capital, the improvement of risk perception and supportive policy will promote peasants to adopt livelihood recovery strategies. Moreover, the results specify that risk perception and supportive policy mediate the relation between livelihood capital and recovery strategy. The findings will be beneficial for policymakers and researchers to understand the mechanisms that peasants adopt livelihood strategies to recover from disasters, and can serve as references for formulating disaster risk reduction and resilience policies.

Effect of Superstitious Beliefs and Risk Intuitions on Genetic Test Decisions

INTRODUCTION

Moving beyond numeric representations of risk perceptions, we examine cognitive causation, or superstitious thinking, and negative affect in risk as predictors of MC1R (i.e., moderate v. high risk) skin cancer genetic testing and responses to this testing.

METHODS

Participants (N = 496) completed baseline assessments using validated measures of cognitive causation (beliefs that thinking about cancer risk increases cancer likelihood) and negative affect in risk (negative feelings generated during risk perception) and subsequently received a test offer. Participants could access a website to learn about and request genetic testing. Those who tested (n = 167) completed assessments of cognitive and affective reactions 2 wk after testing, including the Impact of Events-Revised Intrusive thoughts subscale.

RESULTS

Those with higher negative affect in risk were less likely to return a saliva sample for testing (odds ratio = 0.98, 95% confidence interval = 0.96-0.99). Those with higher cognitive causation reported more fear (b = 0.28-0.31; P's < 0.05). Higher negative affect in risk was associated with more emotion-laden test responses, particularly in those receiving higher-risk as compared with average-risk results.

CONCLUSION

Negative affect in risk did not hamper test information seeking, although it did inhibit the uptake of genetic testing. Those with higher cognitive causation showed more fear regarding their test result, as indicated by higher distress in those who received average-risk results and lower believability in those who received higher-risk results.

Understanding how food safety risk perception influences dietary decision making among women in Phenom Phnom Penh, Cambodia: a qualitative study

OBJECTIVES

To determine women's perception of the risk of food safety and how it relates to diet, health and decision making as part of formative research for a market-based intervention that aims to improve the safety of animal-source foods sold in informal markets.

DESIGN

Qualitative study including in-depth personal interviews with 24 caregivers were conducted and complemented with a second follow-up PhotoVoice interview, which allowed the women to photograph their meals and perceptions of food safety and nutrition. Interview data were analysed using thematic analysis in MAXQDA. Participants were purposively sampled from a larger Safe Food, Fair Food for Cambodia study, conducted from May to August 2018.

SETTING

Urban and periurban neighborhoods of Phnom Penh, Cambodia.

PARTICIPANTS

24 female caregivers (mothers and grandmothers) of children under age 5, each interviewed twice.

FINDINGS

A primary food safety concern expressed was that chemicals (pesticides and other agricultural additives) in animal-source foods, fruits and vegetables may impact the health of their families by causing diarrhoea and problems during pregnancy. This fear created a lack of trust in markets, which influenced their food purchasing behaviours and strategies for making the food safer for their families. These mitigation strategies, including food selection and cleaning, vary among the women but are perceived as important to be able to provide their families with what they define as safe meals.

CONCLUSIONS

Interventions that wish to decrease rates of foodborne illness and increase animal source food consumption should also address the belief that the food system has been compromised by the addition of pesticides and agricultural additives.

Associations between COVID-19 risk perceptions, behavior intentions and worry

BACKGROUND

Risk perceptions are central to health behavior, but some types of risk perceptions may be more strongly connected to behavior than others. This research examined different risk perceptions of COVID-19 and their respective associations with behavior intentions and worry.

PARTICIPANTS AND PROCEDURE

U.S. college students (N = 248) and general adults (N = 300) reported their risk perceptions of COVID-19 - including absolute numerical, verbal, comparative, and feelings of risk - as well as their worry and intentions to do things such as get vaccinated.

RESULTS

Although most risk perceptions related to intentions and worry, feelings of risk were the most strongly and consistently related. The associations showed that the higher people's feelings of risk were, the greater were their intentions and worry.

CONCLUSIONS

Assessing feelings of risk of COVID-19 may provide the best insight into people's perceived threat of this virus.

Effects of mental simulation of future waterpipe tobacco smoking on attitudes, perceived harms and intended use among young adults

The desire to engage in waterpipe tobacco smoking (WTS) may occur when smokers and nonsmokers conjure positive mental simulations of WTS. However, effects of these simulations on desire to smoke waterpipe tobacco and potential mediators are unexplored. This research addressed these effects among young adult waterpipe tobacco smokers and nonsmokers. Two online studies were conducted with adults ages 18-30. In Study 1, 200 smokers, 190 susceptible nonsmokers, and 182 nonsusceptible nonsmokers were randomized to mentally simulate or not WTS in the future. In Study 2, 234 smokers and 241 susceptible nonsmokers were randomized to four arms: no simulation or simulations that varied valence of experience (positive, negative or no valence provided). Main outcomes were immediate desire to smoke waterpipe tobacco, cognitive and affective attitudes, and perceived harms. In Study 1, mental simulations increased the desire to smoke waterpipe tobacco among smokers. In Study 2, asking participants to simulate WTS positively or with no valence instruction increased desire to smoke relative to negative valence instruction or no simulation. Negative simulations reduced perceived probability of smoking within a month compared to positive simulations. Effects on desire to engage in WTS were mediated by cognitive and affective attitudes among susceptible nonsmokers and by cognitive attitudes among smokers. These findings suggest that exploring when and how often mental simulations about WTS are evoked and their potency for promoting prevention and cessation of WTS merit further attention.

Changing Behavior, Attitudes, and Beliefs About Food Safety: A Scoping Review of Interventions Across the World and Implications for Empowering Consumers

Foodborne illnesses are a global public health issue. Responsibility to prevent foodborne disease is shared by many actors along the food supply chain, including consumers. However, consumers often lack knowledge about food safety and behaviors that can reduce risk. Consumers are often targeted for interventions to address these gaps, but a current comprehensive analysis of such interventions globally by type, geography, and outcome is lacking in the literature. In addition, there is a need to understand how individual interventions could be broadened to include the relationships between consumers and other actors in the food system, and how targeted communication strategies can affect behavior. We conducted a rigorous scoping review to assess consumer-facing food safety interventions carried out globally over the past 20 years, and categorized and analyzed them by type of intervention, methods, and outcomes to understand which interventions might be effective in changing consumer behavior, knowledge, attitudes, beliefs, and perceptions on food safety. Ninety-two interventions were reviewed, the majority of which were published in the last 10 years in North America. Most target adults, and 25% are directed at women and mothers. Health or risk communication interventions are becoming increasingly common to move beyond skill-based education and address risk perceptions of food safety that might motivate consumers. Only two studies addressed risk perception in consumers to potentially change food handlers' behavior outside of the home. This review suggests that focusing on risk perception combined with strategies that leverage emotion and trusted sources, such as respected peers or family members, might be useful strategies for interventions.

Use of a language intervention to reduce vaccine hesitancy

Vaccine hesitancy is a major global challenge facing COVID-19 immunization programs. Its main source is low public trust in the safety and effectiveness of the vaccine. In a preregistered experimental study, we investigated how using a foreign language when communicating COVID-19 vaccine information influences vaccine acceptance. Hong Kong Chinese residents (N = 611) received COVID-19 vaccine information either in their native Chinese or in English. English increased trust in the safety and effectiveness of the vaccine and, as a result, reduced vaccine hesitancy. This indicates that language can impact vaccine attitudes and demonstrate the potential of language interventions for a low cost, actionable strategy to curtail vaccine hesitancy amongst bilingual populations. Language interventions could contribute towards achieving the United Nations Sustainable Development Goal of health and well-being.

Risk perception and behaviour during the COVID-19 pandemic: Predicting variables of compliance with lockdown measures

The COVID-19 pandemic and the measures to counteract it have highlighted the role of individual differences in evaluating and reacting to emergencies, and the challenges inherent in promoting precautionary behaviours. We aimed to explore the psychological and cognitive factors modulating behaviour and intentions during the national lockdown in Italy. We administered an online questionnaire (N = 244) that included tests for assessing personality traits (Temperament and Character Inventory; Locus of Control of Behaviour) and moral judgment (Moral Foundations Questionnaire), alongside behavioural economics tasks addressing different facets of risk attitude (loss aversion, risk aversion and delay discounting). We then assessed the extent to which individual variations in these dimensions modulated participants' compliance with the lockdown norms. When assessing their joint contribution via multiple regressions, lockdown adherence was mostly predicted by internal locus of control, psycho-economic dimensions suggestive of long-sighted and loss-averse attitudes, as well as personality traits related to cautionary behaviour, such as harm avoidance, and the authority moral concern. These findings show that a multi-domain assessment of the factors underlying personal intentions, and thus driving compliance with government measures, can help predict individuals' actions during health emergencies. This evidence points to factors that should be considered when developing interventions and communication strategies to promote precautionary behaviours.

Trust, affect, and choice in parents' vaccination decision-making and health-care provider selection in Switzerland

This article examines the relationships between biomedicine, complementary and alternative medicine (CAM) and parents' vaccination decision-making in Switzerland. Our empirical evidence sheds light on an understudied phenomenon-parents switching from one doctor to another provider (often one offering CAM services) around issues that arise during vaccination consultations. This is important to understand since CAM is used by 25%-50% of the Swiss population and is integrated into the Swiss health-care system when offered by biomedically trained medical doctors with additional CAM training. Qualitative data gathered from in-depth semi-structured interviews with parents (N = 30) and ethnographic observations of vaccination consultations (N = 16 biomedical consultations, N = 18 CAM consultations) demonstrate how there was not always a clear-cut, direct relationship between (non)vaccination and parents' use of CAM and/or biomedicine. Borrowing from Hirschman (Exit, voice, and loyalty: Responses to decline in firms, organizations, and states, Harvard Univ. Press, 1970), we frame our analysis by using the concepts of exit, voice and loyalty to describe parents' provider selection and vaccination decision-making process, although only four families in the sample described switching solely because of vaccination-related issues. Findings add to vaccine decision-making literature by describing and analysing the underdiscussed provider-switching phenomenon and by demonstrating the importance of parents' experiences of trust, affect and choice in vaccination consultations as they pursue the best health outcomes for their children.

Viruses, Vaccines, and COVID-19: Explaining and Improving Risky Decision-making

Risky decision-making lies at the center of the COVID-19 pandemic and will determine future viral outbreaks. Therefore, a critical evaluation of major explanations of such decision-making is of acute practical importance. We review the underlying mechanisms and predictions offered by expectancy-value and dual-process theories. We then highlight how fuzzy-trace theory builds on these approaches and provides further insight into how knowledge, emotions, values, and metacognitive inhibition influence risky decision-making through its unique mental representational architecture (i.e., parallel verbatim and gist representations of information). We discuss how social values relate to decision-making according to fuzzy-trace theory, including how categorical gist representations cue core values. Although gist often supports health-promoting behaviors such as vaccination, social distancing, and mask-wearing, why this is not always the case as with status-quo gist is explained, and suggestions are offered for how to overcome the "battle for the gist" as it plays out in social media.

Problemi della previsione in psichiatria

Sono esaminati vari problemi relativi alla previsione in psichiatria. I dati disponibili mostrano, in modo simile alle scienze sociali, ampi limiti nella capacità previsionale, specie per quanto riguarda il suicidio, la violenza e altri aspetti comportamentali. Vengono esaminate le difficoltà che nascono dal cercare di derivare il futuro della persona dal suo passato, la mancata coerenza fra aspetti di personalità e possibili comportamenti e il privilegio dato a strumenti psicopatologici incentrati sul singolo caso, rispetto a quelli attuariali con valutazioni testistiche e statistiche. Vengono anche evidenziati i numerosi bias cognitivi che distorcono le previsioni, in particolare l'errore fondamentale di attribuzione, che privilegia aspetti personologici rispetto a quelli situazionali. Ma altri bias hanno una importante azione distorsiva, da quelli della rappresentatività a quelli della disponibilità, da quelli statistici, al framing o al priming. Emerge una psichiatria molto legata nelle pratiche ancora al senso comune e alla folk psychology, con la ricchezza ma anche i molti errori che la caratterizzano. Di fatto esiste una modesta capacità previsionale riconosciuta alla psicologia popolare e alla psichiatria, ma è legata più a vincoli situazionali che a modelli personologici e psicopatologici e in ogni caso scarsamente affidabile per la previsione clinica in psichiatria.

Disgusting Face, Disease-Ridden Place?: Emoji Influence on the Interpretation of Restaurant Inspection Reports

Every year, millions of Americans get sick from foodborne illness and it is estimated half of all reported instances occur at restaurants. To protect the public, regulators are encouraged to conduct restaurant inspections and disclose reports to consumers. However, inspection reporting format is inconsistent and typically contains information unclear to most consumers who often misinterpret the inspection results. Additionally, consumers are increasingly searching for this information in a digital context. Limited research explores inspection reports as communication tools. Using affect-as-information and ELM as theoretical frameworks, this experiment investigated how discrete emotions (e.g., disgust) conveyed through pictorial cues (i.e., emojis) influenced consumers' processing of inspection reports. Participants, recruited from Amazon's MTurk, were randomly assigned to one of six experimental conditions in a 3 (emoji: smiling vs. disgusted vs. none) x 2 (violation level: low vs. high) between-subjects design. Then, participants completed a questionnaire regarding perceptions and cognitive processing of the message. Results revealed that, compared to text, disgusted face emoji increased risk perceptions and avoidance behavior. In terms of emotion, smiling face emoji motivated participants to feel more emotions related to sanitation. In turn, positive feelings decreased elaboration likelihood. As predicted by ELM, involvement also predicted elaboration, such that participants who were highly involved with inspection reports elaborated more than those less involved. Involvement also moderated the relationship between emoji presented and elaboration. Practical implications are also discussed.
