Patients’ perceptions matter: Risk communication and psychosocial factors in orthodontics

Effective risk communication is essential for achieving patient-centered oral health care, but the limited understanding of patients' subjective perceptions of orthodontic-related risks hinders this process. This study aimed to investigate adults' awareness, concerns, and risk-avoidance behaviors about long-term orthodontic risks, exploring their relationship with psychosocial factors. We included 498 adult patients (mean age, 27.3 ± 6.8 years; women, 75.5%) during their initial visits to the orthodontic department at a hospital in Chengdu, China. Participants' understanding of orthodontic risks was gauged before and after exposure to the Oral Health Education Comics (OHEC), a specifically designed digital tool. Concurrently, we used logistic regression models to investigate the associations between patients' depression, anxiety, self-esteem, perfectionism, and dentofacial esthetics with risk perceptions. Approximately 79.5% of participants initially reported low awareness of orthodontic risks, with most knowledge from online sources. Notably, the percentage of participants with high awareness increased to 64.8% after OHEC. The negative facial soft-tissue change was most concerning for participants: 53.4% showed high concerns, and 28.1% showed high avoidance. Furthermore, linear regression indicated positive associations between depression (β= 0.42 [95% confidence interval {CI}, 0.07-0.77]) and anxiety (β= 0.76 [95% CI, 0.35-1.18]) with orthodontic risk concerns, whereas risk avoidance was positively associated with depression (β= 0.62 [95% CI, 0.27-0.97]), anxiety (β= 1.09 [95% CI, 0.68-1.50]), and perfectionism (β= 0.24 [95% CI, 0.02-0.46]). Findings emphasize the imperative of streamlined risk communication in orthodontics. By incorporating comprehensible tools such as OHEC and integrating psychosocial evaluations, more refined patient-practitioner communication and psychosomatic-based dental care can be achieved.

Research progress in stroke risk perception assessment tool.

One of the main illnesses in the globe that causes impairment and death in people is stroke. In the globe today, it ranks as the second leading cause of death and the leading cause of death in China. This paper analyses into the critical role of risk perception in developing individual awareness of stroke risk and encouraging proactive preventive health behaviors, essential for effective primary stroke prevention strategies and reduced stroke incidence. It discusses the concept of risk perception, the content and dimensions of global stroke assessment tools, and their application status, aiming to provide insights for their development and intervention research. Risk perception encompasses subjective assessments of stroke likelihood and severity, influenced by personal experiences, knowledge of risk factors, beliefs about prevention effectiveness, and emotional responses. Global stroke assessment tools, like the Framingham Stroke Risk Score and CHA2DS2-VASc Score, evaluate stroke risk based on factors such as age, gender, blood pressure, and cholesterol levels. In order to improve risk perception and proactive health management and lower the burden of strokes, the paper assesses the advantages and disadvantages of these tools and makes recommendations for improving accessibility, customizing interventions, running educational campaigns, promoting multidisciplinary collaboration, and integrating technology. By combining the research tools of stroke risk perception, it is found that the evaluation tools are mostly single-dimensional evaluation tools centered on the two dimensions of onset possibility and susceptibility. Some scholars have developed multi-dimensional evaluation tools, but the evaluation population is relatively limited, and the evaluation system lacks comprehensiveness and systematization.

Compliance with social norms in the face of risks: Delineating the roles of uncertainty about risk perceptions versus risk perceptions.

Social norms are often considered as behavioral guidelines to mitigate health and environmental risks. However, our understanding of the magnitude of their impact on risk-mitigating behaviors and how perceptions of risks affect the magnitude remains limited. Given the increasing importance of understanding factors influencing behavioral responses to health and environmental risks, this research examines whether the relationship between social norms and behavioral intention to mitigate health and environmental risks is a function of (1) risk perceptions and (2) uncertainty about risk perceptions. A cross-sectional survey involving a national sample (N=803) across three health and environmental risks (i.e., infectious diseases, climate change, and water shortage) is conducted. The results reveal a three-way interaction between descriptive norms, uncertainty about susceptibility, and uncertainty about severity on behavioral intention to mitigate the risk. Individuals exhibit the strongest intention to engage in risk-mitigating behaviors when they perceive prevailing social norms and are uncertain about their susceptibility to the risk and the severity of the risk. Moreover, injunctive norms interact with uncertainty about susceptibility to influence behavioral intention, such that the more uncertain individuals feel about their vulnerability to a risk, the stronger the impact of injunctive norms is on behavioral intention. Neither descriptive nor injunctive norms interact with perceived risks to influence behavioral intention. This study contributes valuable insights into the interplay between social norms, uncertainty about perceived risk, and behavioral intention, and offers valuable theoretical and practical implications.

The effect of social media communication on intention to vaccinate against COVID-19: A relationship mediated by perceptions of vaccine efficacy and safety

ABSTRACT Although previous literature has found significant effects of social media communication (SMC) on intention to vaccinate, the effect of the sources of SMC has not been explored. To fill this gap, this study investigates a) the effects of official sources and user-generated SMC on intention to vaccinate against COVID-19, and b) the mediating effects of perceived vaccine efficacy, safety, and risk perception on the relationship between SMC and intention to vaccinate against COVID-19. Online survey data (n = 428) was analysed using structural equation modelling (SEM). Results revealed that official sources SMC is positively associated with vaccine intention while user-generated SMC had no significant association. Mediation analysis revealed a partial mediation effect of perceived vaccine efficacy and safety in the relationship between official source SMC and intention to vaccinate against COVID-19, while a full mediation effect of perceived vaccine efficacy and safety was found between user-generated SMC and intention to vaccinate against COVID-19. The mediating effect of perceived risk was not found.

Extending X-reality technologies to digital twin in cultural heritage risk management: a comparative evaluation from the perspective of situation awareness

DT systems, characterized by real-time capabilities, high precision, and high integration, have become essential in various domains. In the context of cultural heritage, a DT system encompasses comprehensive information about heritage sites, contextual data, and expert knowledge, forming a complex dynamic system. The substantial volume of information and diverse sources significantly increases the cognitive load for management personnel in understanding on-site situations. This study, from the perspective of situational awareness, introduces X-reality technologies (VR and AR) into DT systems for cultural heritage risk management. The aim is to evaluate the effectiveness of different X-reality technologies in cultural heritage risk perception and their impact mechanisms. A total of 184 participants were divided into two groups and experienced three different applications (2D desktop, VR, and AR). Using situational awareness rating techniques, participants' responses were measured across three dimensions: attention resource demand, attention resource supply, and understanding of the situation. SEM was employed to estimate the stability of the scale data. The results indicate that, compared to traditional 2D desktops, both VR and AR demonstrate advantages in enhancing heritage risk situational awareness. However, in AR mode, no significant advantages were found in the dimensions of attention resource demand and attention resource supply compared to traditional 2D desktop applications. Furthermore, a significant difference in immersion between VR and AR was found to affect the attention resource demand dimension. Although the results suggest differences in the interactivity of VR and AR in affecting the attention resource demand dimension, no significant differences were found. By comprehensively understanding the functional mechanisms of X-reality technologies in influencing cultural heritage risk situational awareness, this study provides design references for constructing DT systems for cultural heritage risk management. Additionally, it offers insights for heritage site managers, experts, and stakeholders to enhance risk perception efficiency, promoting more effective risk assessment, analysis, and strategic decision-making, thereby reducing damage to cultural heritage.

PEER TO PEER LENDING : GENERATION Z ATTRACTION FACTORS AND FUTURE IMPLICATIONS

This study is about the factors of behavioral intention to borrow from the perspective of Generation Z toward peer-to-peer lending. This study applied primary data by collecting surveys distributed to Gen Z on Java Island. The sample used was 44 male respondents and 110 female respondents. Factors that influence borrowing intention were tested with SEM PLS 4.0. The research shows that the variables of utilitarian value, risk perception, and financial literacy are significant to the behavioral intention of Peer To Peer Lending. In addition, the findings show that the variables of convenience and safety do not determine behavioral intention in Peer To Peer Lending. This research also explores how financial technology, such as peer-to-peer lending, can facilitate Generation Z's access to finance. The implications of this research highlight the importance of financial knowledge and planning for Gen Z for its future. These findings provide insights for fintech companies to design products and services that suit Generation Z's specific preferences and needs. The target market for peer-to-peer lending companies needs to be adjusted in their marketing strategies.

Proposal of a method to analyze children’s flood risk exposure and risk perception using GPS tracking data and questionnaire survey

BackgroundClimate change has made the relationship between disaster and sustainable development more critical. Especially in developing countries, disasters frequently devastate local communities and hinder progress. Children are at a higher risk during catastrophes; however, their knowledge of disaster risk is limited. Education for disaster risk reduction can bring the necessary changes for a safe society. School disaster prevention education can raise awareness through lectures and games, but interactive dialogues between students and teachers can be more effective. Also, GPS tracking can be a valuable tool for understanding people’s behavior during disasters.MethodologyThis study proposes a method to analyze the relationship between students’ daily behavior and their experiences of flood damage and preparedness for disaster risk. It is a simple method using questionnaires and GPS loggers and can be applied in mountainous areas in developing countries where equipment is inadequate. The proposed method will be used to understand the current state of disaster risk among children and identify disaster risk reduction issues. The study area lies in Paluntar Municipality, Gorkha district, Nepal. Forty-five students from two schools in the region participated in the study.ResultsThe results showed that students who commute to school in areas inundated by heavy rainfall in recent years were not adequately prepared for disasters, even though they had experienced flood damage in the past and were significantly more concerned about future harm. Our field observations and interviews of teacher-student relationships showed that students were very attentive to their teachers’ instruction. Teachers understand the dangers of heavy rainfall and how to prepare for it, but students need to learn how to deal with it. In other words, the school staff’s disaster education to the students effectively reduces disasters. Early warning is needed when severe floods are expected during the rainy season.

Active offer of Tdap vaccination in a cohort of healthcare workers of Maternal and Neonatal Department: Data from a large hospital in Southern Italy

Pertussis is a vaccine-preventable respiratory disease. Pertussis vaccination is currently mandatory for all children in Italy, and is administered in three doses at the beginning of the third, fifth, and twelfth month of life, respectively. Booster doses are also recommended at five-six years, at eleven-twelve years, and then once every ten years. Healthcare workers (HCWs) are a high-risk population for pertussis. Strategies to increase HCWs’ compliance to this vaccination have not been investigated in depth. Our study investigates the determinants of acceptance of a “soft nudge” vaccination campaign in a large hospital in Apulia (Southern Italy).HCWs from the Gynaecology and Neonatology Units of Bari’s Policlinico General Hospital were screened in June 2023 for pertussis vaccination. Non-vaccinated subjects were offered a vaccination appointment. Vaccination determinants were studied, and a logistic regression model was built to identify determinants that significantly influence vaccination acceptance.At the time of screening, only 31.34% of target HCWs (68/217) had already been vaccinated. After the active call intervention, vaccine coverage rose to 70.00% (152/217). Significantly higher coverage was found in the Neonatology Unit (30/43, 69.77%) than in the Gynaecology unit (54/106, 50.94%) (Chi2: 4.41; p-value: 0.036). A logistic regression model confirmed a higher compliance to vaccination in HCWs staffed in the Neonatology Unit (Chi2: 2.08; 95%CI: 1.04 – 4.73; p-value: 0.038).Our intervention increased vaccination coverage in a high-risk cohort. The solicitation was effective, as communication with a trained specialist might have improved the subjects’ perception of vaccination and individual risk of contagion and transmission to others. A synergistic approach, mixing active call with a vaccination mandate, might have greater effectiveness.

Are Thai mangrove managers aware of the potential threat posed by sea level rise?

Rapid sea level rise (SLR) represents a novel threat to mangroves, which could adapt through vertical accretion or landward expansion. Depending on tidal conditions and stressors, managers will likely have to intervene to enhance the adaptive capacity of mangroves. However, managers must be aware of, understand, and anticipate the risks of SLR-induced habitat degradation to plan adaptive measures, which must be supported by administrative resources, political will, and stakeholder engagement. Here, we studied how cognitive, experiential, and organizational factors influence risk awareness and adaptive management capacity of communal and state-based managers. In telephone-based interviews, the risk perception of 60 community-based and 23 governmental mangrove managers in Thailand was assessed to gain insights into their awareness and understanding of SLR risks, current management practices and adaptive measures, and the extent of their collaboration and stakeholder engagement. The findings show that most managers acknowledge the presence of SLR (72%) but perceived the adaptive capacity of mangroves as sufficiently high and the risk of SLR-induced degradation as minimal (63%), regardless of their affiliation. However, few respondents (18%) were aware that SLR would prolong hydroperiods and increase waterlogging stress of mangrove trees. The survey also revealed organization-specific biases. State officials cited a high level of uncertainty due to limited research and monitoring preventing them from planning adaptive measures. Community managers relied on their past experiences of mangrove recovery following disturbances, which might be unsuitable for informing management decisions in response to the novel threat of SLR. These findings indicate a lack of knowledge and guidelines for understanding and addressing SLR impacts. Additionally, there was an observed optimism bias among community managers, where past successful recoveries led to an overestimation of mangroves' adaptive capacity. Knowledge transfer and awareness-raising among mangrove resource stakeholders are critical for developing adaptation measures.

Associations between Kratom risk perceptions and intention to legalize in Malaysia

ABSTRACT Background or Objective This paper delves into the dichotomy of Kratom in Malaysia, designated as an illegal substance under the Poison Act 1952. Amidst heightened concerns regarding Kratom usage, debates revolve around balancing perceived benefits and potential adverse effects, particularly in pain management. Employing the perceived risk theory, the study aims to scrutinize the intention to legalize Kratom. Methods Data from 335 respondents form the basis of the study. The perceived risk theory serves as the framework for understanding the complexities of Kratom legalization to legalize in Malaysia. The study employs a structured questionnaire to assess social, financial, physical, psychological, and performance risks. Results The findings indicate significant impacts of social, financial, physical, and psychological risks on behavioral intentions toward Kratom legalization. However, performance risk does not exhibit a significant impact on the intention to legalize Kratom. Conclusions This study contributes crucial insights for policymakers, highlighting the intricate dynamics of Kratom legalization. Addressing various risk factors is deemed essential for the formulation of effective regulatory policies. The results emphasize the need for nuanced considerations in understanding and managing the legalization of Kratom in the Malaysian context.

Potential tourists’ response to nuclear and radiation crises from risk information to actions

ABSTRACT The release of treated wastewater from the Fukushima Daiichi Nuclear Power Plant in Japan has sparked concerns and controversy over the potential risks associated with nuclear-affected destinations. This study uses grounded theory to elucidate the broader definition of nuclear and radiation crises, while comprehensively analysing potential tourists’ decision-making processes in the face of such risks. Focus groups and interviews were conducted in Asia with participants from various countries, revealing how potential tourists receive, process, and perceive risk information cues, make decisions, and adopt behavioural responses. This research contributes to the existing literature in an interdisciplinary manner, providing insights and recommendations for stakeholders involved in tourism and risk management.

The Driving Factors of Food Waste in Chinese Urban Households: A Qualitative Study Based on Grounded Theory

Food waste has become an increasingly common and serious global problem, affecting the guarantee of food security in China and the sustainable development of the national agricultural and food system. Urban households are the main source of food waste on the consumer side. Given China’s unique culture, economy, and social environment, the drivers of food waste in urban households need to consider broader social, psychological, and situational factors in order to provide a basis for formulating and implementing targeted policy measures. This article conducts a grounded theoretical analysis of semi-structured interview data from 56 urban households in China and constructs a driving factor model for food waste in urban households in the Chinese context. Research has found that the influencing factor system of food waste in Chinese urban households includes seven interrelated main categories. Among them, risk perception has a direct effect on responsibility awareness and behavioral tendencies, responsibility awareness and environmental pressure have a direct effect on behavioral tendencies, behavioral tendencies have a direct effect on behavioral choices, perception barriers play a moderating role in the impact of risk perception on responsibility awareness and behavioral tendencies, and behavioral constraints play a moderating role in the impact of behavioral tendencies on behavioral choices. This study enriches the research on the mechanism of food waste behavior in Chinese households, providing scientific basis for the formulation of intervention strategies for food waste in Chinese households, and also providing reference for revealing the mechanism of food waste behavior in other countries with similar cultural backgrounds.

The socio-technical short-term implications of drinking water hoarding on supply reliability

ABSTRACT Panic buying during crises, like the initial hoarding of toilet paper amid COVID-19 restrictions, is mainly driven by social and emotional factors influenced by risk perception and social media content. Similarly, unreasonable drinking water hoarding, i.e., simultaneous withdrawal of water by a large number of customers, can influence the performance of water supply systems (WSS). Decreasing performance (e.g., more friction losses and therefore a smaller outflow rate at faucets) can cause a negative feedback loop that might trigger further water hoarding behaviours. This research explores the socio-technical implications of water hoarding in crisis situations within a WSS. An analysis of an Alpine WSS in Austria reveals that up to 40% of households, with a filling rate of 0.1 L/s (bathtub filling), can hoard without performance drop and negative feedback. Beyond this threshold, impacts become noticeable, leading to inadequate water supply for some households, causing disruptions and negative feedback loops. This emphasizes the need for information campaigns to counter false information, preventing emotional triggers. In conclusion, the research highlights the interplay between technical and social factors in crisis water demand management, stressing the importance of informed interventions to mitigate hoarding behaviour and maintain efficient WSS operation.

Interest in and Willingness to Use PrEP: A Cross-Sectional Study of Individuals with Problematic Substance Use Residing in a High HIV Prevalence Jurisdiction.

Although it is an effective HIV prevention method, pre-exposure prophylaxis (PrEP) is underutilized in the Southern US. Many people who use drugs (PWUD) have increased susceptibility to HIV which could be lessened by using PrEP. Potential barriers to PrEP use include lack of awareness of PrEP, low knowledge about HIV prevention, low self-efficacy for HIV prevention, inaccurate risk perceptions, and anticipated stigma. The current study examined predisposing, enabling, and reinforcing factors that may predict interest in PrEP. The purpose of the current study was to explore factors associated with interest in and willingness to use daily oral and long acting injectable PrEP among sexually active adult PWUD. The data were collected from adult participants (n = 270) residing in Harris County, TX, who self-reported problematic substance use and who reported oral, anal, or vaginal sex in the six months prior to completing the survey. The survey was distributed and completed online via Qualtrics Panels in March of 2022 and included measures of PrEP and HIV knowledge, PrEP stigma, sexual health self-efficacy, experiences of discrimination, health literacy, and medical mistrust. The majority of participants reported circumstances or behaviors that increased their susceptibility to HIV. Findings indicated that PrEP user stereotypes and PrEP anticipated disapproval by others were associated with interest in using daily oral PrEP and willingness to use long acting injectable PrEP. These results provide insight into reasons for low PrEP uptake among PWUD who live in a high HIV prevalence jurisdiction. Implications for HIV prevention intervention are discussed.

“I’m better than you”: assessing the presence of optimistic bias among Italian hunters

According to the latest scientific evidence, consumers appreciate hunted wild game meat (HWGM), but its consumption may expose them to some risks. Hunters produce HWGM, even if they may find it hard to identify themselves as food producers since in Western countries, hunting is practiced mostly as a leisure activity. Thus, hunters may underestimate the risk associated with HWGM handling, failing to preserve its safety during the production process. To test this hypothesis, our study aims to explore the presence of optimistic biases (OB) in a sample of Italian hunters. A sample of 408 hunters was asked to indicate their own risk and the perceived risk of their peers causing a foodborne disease to the final consumer, as well as the practices implemented during the phases of HWGM handling and preparation. Moreover, information about HWGM destinations, hunters' knowledge of basic principles of food safety, and risk perceptions of HWGM preparation were collected. Our results show that hunters generally tend to perceive themselves as "better than their peers" in performing actions to preserve HWGM safety, especially if the peers are unfamiliar to the respondent. Furthermore, OB correlates knowledge of basic principles of food safety with risk perceptions of HWGM preparation-related practices. Finally, hunters perceived themselves as "nature lovers" and "hunting enthusiasts" and did not recognize their role as food producers. Therefore, our findings emphasize the importance of improving hunters’ training to preserve public health, addressing the need for more targeted strategies able to enhance hunters’ awareness of their role as food producers.

Preexisting Mental Disorders and Mental Distress During the Pandemic : The Roles of Stress, Risk Perception, and Loneliness.

Purpose. The COVID-19 pandemic has imposed unprecedented stressors on individuals globally, leading to significant mental health challenges. This study examines the relationship between perceived adversities experienced during the pandemic-such as stress, risk perception, and loneliness-and the mental health outcomes of individuals with a specific focus on those already grappling with mental disorders. Methods. The study analyzed data from 8,259 adults who participated in surveys between waves 4 (April 2020) and 29 (June 2021) of the Understanding American Study. Participants self-reported their psychiatric diagnosis history and completed self-report measures of mental distress (PHQ-4), perceived stress, risk perception, and loneliness. Results . Those with preexisting comorbid mental disorders reported higher levels of mental distress, COVID-19 risk perception, perceived stress as well as more days experiencing loneliness during the pandemic. Perceived adversities-stress, risk perception, and loneliness-were all positively associated with increased mental distress, indicating the risk factors for mental distress during the pandemic. Among these factors, loneliness was identified as the primary contributor, accounting for 30%-40% of the mental health gap between individuals with and without preexisting mental diagnoses. Also, the detrimental impact of these adversities was more pronounced for those with preexisting mental disorders. Conclusion. The research highlights that those with preexisting mental disorders, particularly those with comorbidities, face an increased risk of experiencing mental distress during the COVID-19 pandemic. These findings underscore the critical importance of providing targeted support and interventions specifically designed for this vulnerable population, with a particular focus on addressing loneliness.

Do COVID-19 related primary emotions affect risk perceptions, efficacy beliefs, and information seeking and behavior? Examining emotions as audience segments

IntroductionPrimary emotions among the populace during global health crises, such as the COVID-19 pandemic, provide valuable insights. Guided by appraisal theories of emotions, this study explores emotional segmentation by mapping primary emotions related to COVID-19 and investigating their impact on cognitive and behavioral outcomes, including risk perceptions, efficacy beliefs, behavioral intentions, prevention behaviors, and information seeking/avoidance.MethodsStudy 1 surveyed young adults (N = 1,368) to investigate their emotions about COVID-19 and examine the effect of these emotions on risk perceptions, efficacy beliefs, and behavioral intentions regarding mask-wearing and physical distancing. Study 2 replicated Study 1 with a quota-based national sample of U.S. adults (N = 8,454) and further tested the effect of primary emotions on preventive behaviors and information seeking/avoidance.ResultsResults indicated that most people experienced negative emotions, such as sadness, anger, and anxiety. These emotions were associated with varying levels of risk perceptions, efficacy beliefs, behavioral intentions, actual behaviors, and information seeking/avoidance. Notably, across both studies, anxious individuals demonstrated more favorable health-related perceptions and behavioral outcomes compared to those experiencing anger.DiscussionThese findings offer insights into the emotional experiences of individuals during the COVID-19 pandemic and highlight the significant impact of these emotions on risk perceptions and health-related behaviors. Understanding these emotional responses can inform public health strategies and communication efforts during health crises.
