Socially Equitable Public Service Provision: Towards Inclusive Coproduction of Public Infrastructure

ABSTRACT The challenge of building and maintaining public infrastructure in the face of climate change and natural hazards necessitates greater citizen involvement in decision-making processes. Coproduction aims to ensure equitable service distribution by engaging a diverse range of citizens. However, the literature highlights disparities, with certain citizens having greater resources for participation. This study explores how individual socioeconomic factors and risk perceptions influence citizens’ willingness to engage in coproduction. Coproduction has been criticized for excluding marginalized populations, we analyze how multilevel factors shape willingness to participate in two modes of coproduction: co-planning and co-investing. The results indicate that risk perception is the most significant factor driving citizens’ willingness to coproduce. Furthermore, well-educated or wealthy citizens are more inclined to participate. This study proposes an inclusive approach to coproduction, aiming to ensure equitable public service delivery regardless of socioeconomic status.

Cardiovascular disease risk perception among community-dwelling adults in southwest Nigeria: A mixed-method study

Objective The rising prevalence of cardiovascular diseases (CVD) remains a global concern. In Nigeria, the current prevalence of CVD was 76.11% with its attendance burden. The CVD risk perception of individuals is a precursor to the desired lifestyle modification necessary for CVD prevention and management. This study assessed the CVD risk perception and sociodemographic determinants among rural and urban dwellers in southwest Nigeria. Methods The study employed a convergent parallel mixed-methods design involving concurrent data collection. The participants’ CVD risk perception was obtained using the Perception of Risk of Heart Disease Scale (quantitative data) and a validated focus group discussion (FGD) guide (qualitative data). Quantitative analysis was completed using descriptive statistics, Phi, Cramer’s V, and multivariate linear regression, while the FGD was thematically analysed. Results The quantitative study involved 1,493 participants (62.4% women) with a mean age of 46.90±15.65 years, while the FGD involved 53 participants (52.8% women) with a mean age of 50.10±13.5 years. Over a quarter (28%) of the participants had a poor CVD risk perception; the mean score was 44.40±8.07. Rural residents had a significantly poorer CVD risk perception than their urban counterparts (Mean difference = -3.16, p<0.001). Having tertiary education (β = 0.100, p < 0.001), living in urban areas (β = 0.174, p<0.001), and living in Lagos (β = 0.074, p = 0.013) and in Oyo, other than Ogun state (β = -0.156, p<0.001) significantly predicted having a good perception of CVD risk. FGD produced three themes: knowledge about CVD, CVD risk factors, and CVD prevention. Conclusion Participants had a fair understanding of the causes and prevention of CVD. Yet, a substantial portion underestimated their own risk of developing CVD, particularly rural dwellers and people with lower education. More public health education is required to improve the CVD risk perception in southwestern Nigeria.

Outdoor worker knowledge of ticks and Lyme disease in Québec.

Lyme disease is a well-known occupational risk across North America caused by exposure to Borrelia burgdorferi via blacklegged ticks (Ixodes scapularis). As the geographic range of B. burgdorferi advances with the increasing distribution of blacklegged ticks, more outdoor workers are at risk of contracting Lyme disease. In this study, we examined the demography and personal perceptions of outdoor workers within one framework to better determine the overall risk for those working outdoors. We analysed outdoor worker knowledge of ticks and of behaviours that can prevent tick bites and Lyme disease. We then compared these risk perceptions of individuals across age, sex, education, and industry, as well as time spent outdoors. We tested the hypothesis that the risk perception of an individual and their knowledge of Lyme disease transmission was dependent on their demographics, experience in their job, and the region in which they spend time outdoors. We estimated a knowledge-based risk score based on individuals' answers to a questionnaire on risk perception given to voluntary participants who work outdoors. Those who had higher risk scores were more at risk. We found that knowledge-based risk scores were correlated with geographic risk levels and with the number of hours per day spent outdoors. Those who work longer hours and who work in areas with mid-level risk had higher risk scores. Those who spend more time outdoors recreationally had lower risk scores. Further examination and acknowledgment of the reasoning behind why these factors are affecting workers' risks must be considered to recognize that it is not necessarily demographics or geographically high-risk areas that affect an individual's risk. Workers' knowledge of these risks is affected by several variables that should be taken into consideration when implementing safety measures and awareness programs.

Willingness of Women at Increased Risk of Breast Cancer to Participate in Prevention Trials.

The factors affecting women's willingness to participate (WTP) in breast cancer (BC) prevention trials are poorly understood. This study aimed to identify the characteristics of interventions associated with a higher WTP among high BC risk women. Women who self-identified as being at an increased risk of BC were recruited to a cross-sectional study of WTP in BC prevention trials. Responses were dichotomized into more willing (a lot and moderately) and less willing (some, a little, and not at all), and responses were compared by patient characteristics and intervention type. Of 143 participants, 81.2% (116) completed ≥30% of a Likert-type scale questionnaire on WTP in various intervention types for BC prevention. Overall, WTP in BC prevention studies was high, with 82.7% more willing, including 69.0% and 70.7%, respectively, for unspecified physical activity and dietary interventions. WTP differed significantly by the duration of diet-based and physical activity behavior change interventions: decreasing with 12- versus 3-month diet-based interventions (P < .0001) and decreasing for 1 hour versus 30 minutes of low-intensity exercise/day (P < .0001). For interventions involving medication, only 18.1% expressed being more willing to participate, and WTP decreased significantly when side effects were presented. WTP was influenced by BC risk gene mutation status, with WTP among gene carriers higher compared with nongene carriers (52.6% v 30.2%, P = .018). WTP in BC prevention trials was the highest for women with known genetic risk and for interventions involving a behavior change. Medications with side effects had the lowest WTP. For behavior change, WTP was negatively influenced by intervention duration beyond a few months, indicating that individual perception of BC risk and inconvenience strongly influence WTP.

Gap between estimated cardiovascular risk and individual risk perception: a survey from a cardiovascular prevention center.

Abstract Background Cardiovascular risk scores represent a great achievement of preventive cardiology, since they allow to stratify individual risk. The recently updated European Society of Cardiology Scores offer an accurate cardiovascular risk estimation. However, a gap between perceived and calculated risk may strongly interfere in healthy lifestyle changes as well as in cardioprotective drugs adherence. Purpose: The aim of the present study was to evaluate and quantify the above-mentioned gap. Methods A cohort of subjects referred to our Cardiovascular Prevention Center were included in the present study. Cardiologists assessed each tradional and emerging risk factor in terms of presence or absence, severity, distance from target, and the cardiovascular risk was calculated using appropriate ESC scores. Each subject filled out a questionnaire in which they were asked to declare their perceived cardiovascular risk and to report, among all the traditional and emerging cardiovascular risk factors, which ones they believed to have greater impact on their individual risk. Results 366 consecutive subject were included, 70% in primary prevention and 30% with atherosclerotic cardiovascular disease, mean age was 65 years, male gender was prevalent (57%), arterial hypertension (AHT) was found in 78,7% (43,4% uncontrolled), dyslipidaemia in 91,5% (87,5% not at target), diabetes in 18,6%, smokers were 12,9% and 24,4% had obesity. Among emerging risk factors, sedentary lifestyle was found in 63%, while 18% reported regular aerobic physical activity, mediterranean diet adherence was found in 26% and moderate-to-severe perceived anxiety in 23%, depression in 17% and stress in 66%. 6,6% had low risk cardiovascular risk, 16,1% intermediate, 38,0% high and 39,3% very high. A concordance between estimated and perceived risk was found in 18,9% while a discordance in 81,1%; 93,3% underestimate their risk, while 6,7% only overestimate it (figure 1A). A significant higher rate of discordance was found with the progressive increase of the risk (p&amp;lt;0.0001). Different perceived cardiovascular risk among each estimated classes of risk was shown in figure 1B and figure 2; of note only 11% of high risk and 8% of very high risk were concordant in their risk perception. In particular, elderly (p&amp;lt;0.001), male (p&amp;lt;0.001), subjects with AHT (p=0.001) and dyslipidaemia (p=0.02) showed higher rate of underestimation while younger (p&amp;lt;0.001), female (p&amp;lt;0.001) as well as anxiety (p=0.047) and depressed (p=0.010) had higher rate of overestimation. Conclusions A high rate of subject underestimate its cardiovascular risk; the higher the risk, the higher the gap between perceived and estimated risk. This risk gap represents a "risk within the risk". for these reasons it is necessary to increase all efforts towards a more effective health education in the field of cardiovascular prevention in order to reinforce patients awareness and physician-patient alliance.Figure 1Figure 2

The Social Contagion of Risk Perceptions of Emerging Technologies through Evolutionary Game in Networks

Emerging technologies are leading the fourth industrial revolution, bringing profound changes to modern life. However, the contagion of public risk perceptions pertaining to these technologies may result in new social stability risks according to the social amplification of risk framework (SARF). As such, understanding the formation and contagion mechanisms behind public risk perceptions of emerging technologies is critical to promoting their increased receptivity. Based on an evolutionary game theoretical approach to complex networks, this paper constructs a social contagion model of the risk perception of emerging technologies and uses simulations to analyze the influence of factors such as individual cognition and social environment. Results indicate the following: (1) the rate of risk perception contagion gradually increases with the level of individual risk perception and trust in communicators; (2) the risk perception contagion rate gradually decreases as the level of risk governance participation increases; and (3) comparing different social networks, kinship networks have a greater effect than social media networks on risk perception contagion.

The impact of perception bias for cardiovascular disease risk on physical activity and dietary habits

ObjectiveCardiovascular disease (CVD) remains a significant public health challenge in China. Accurate perception of individual CVD risk is crucial for timely intervention and preventive strategies. This study aims to determine the alignment between CVD risk perception levels and objectively calculated CVD risk levels, then investigate the disparity in physical activity and healthy diet habits among distinct CVD risk perception categories. MethodsFrom March to August 2022, a cross-sectional survey was conducted in Zhejiang Province using convenience sampling. Participants aged between 20 and 80 years, without prior diagnosis of CVD were included. CVD risk perception was evaluated with the Chinese version of the Attitude and Beliefs about Cardiovascular Disease Risk Questionnaire (ABCD-C), while objective CVD risk was assessed through the Prediction for Atherosclerotic Cardiovascular Disease Risk (China-PAR) model. Participants’ demographic information, self-reported physical activity, and healthy diet score were also collected. ResultsA total of 739 participants were included in the final analysis. Less than a third of participants (29.3%) accurately perceived their CVD risk, while 64.5% over-perceived it and 6.2% under-perceived it. Notably, half of the individuals (50.0%) with high CVD risk under-perceived their actual risk. Compared to the accurate perception group, individuals aged 60-80 years old (OR = 6.569), currently drinking (OR = 3.059), and with hypertension (OR = 2.352) were more likely to under-perceive their CVD risk. Meanwhile, participants aged 40-<60 years old (OR = 2.462) and employed (OR = 2.352) were more likely to over-perceive their risk. The proportion of individuals engaging in physical activity was lowest in the under-perception group, although the difference among the three groups was not statistically significant (χ2=2.556, P=0.278). In addition, the proportion of individuals practicing healthy diet habits was also lowest in the under-perception group, and a significant statistical difference was observed among the three groups (χ2=10.310, P=0.006). ConclusionOnly a small proportion of participants accurately perceived their CVD risk, especially among those with high actual CVD risk. Individuals in the under-perceived CVD risk group exhibited the lowest rates of physical activity engagement and healthy diet adherence. Healthcare professionals should prioritize implementing personalized CVD risk communication strategies tailored to specific subgroups to enhance the accuracy of risk perception.

Beyond perceived risk: COVID-19 vaccination more strongly linked to individual risk perception in wheat areas than rice areas

Vaccines save lives, but vaccine hesitancy remains a global health challenge. That makes it critical to explore the factors that influence whether people get vaccinated. Perceived risk is a pivotal factor in traditional theories of health behavior, such as the Risk Perception Attitude framework and the Health Belief Model. However, studies have found that these models are less predictive of COVID-19 vaccination in some cultures. Studies that test culture by comparing nations are useful, but nations have different healthcare systems and policies that are hard to equate and control for. We addressed this question by testing regional cultural differences in China. Drawing on the rice theory, we compared residents in China's historical rice-farming areas (which are more interdependent) with those in wheat-farming areas (which are more independent). Our survey data from 1872 participants in 29 provinces found that models of perceived risk explained COVID-19 vaccination mainly in historically wheat-farming areas. Conversely, in historically rice-farming areas, perceived risk did not explain vaccination behavior. These findings suggest that cultural factors that are rooted in historical farming practices influence vaccination behaviors. By comparing regions within the same country, we can rule out confounds of national policy and healthcare systems. These insights could help policymakers understand how to tailor vaccination campaigns to people from different cultures.

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.

Correlates of oral pre-exposure prophylaxis cessation among men who have sex with men in China: implications from a nationally quantitative and qualitative study

BackgroundSeveral studies have demonstrated the population-level effectiveness of oral PrEP in reducing the risk of HIV infection. However, oral PrEP utilization among MSM in China remains below 1%. While existing literature has primarily focused on oral PrEP preference and willingness, there is limited exploration of the underlying factors contributing to oral PrEP cessation in China. This study aims to fill this gap by investigating the factors associated with oral PrEP cessation among MSM in China.MethodsAssisted by MSM community organizations, we collected 6,535 electronic questionnaires from 31 regions across China, excluding Taiwan, Hong Kong, and Macau. The questionnaire focused on investigating MSM's awareness, willingness, usage, and cessation of oral PrEP. Additionally, 40 participants were randomly chosen for key informant interviews. These qualitative interviews aimed to explore the reasons influencing MSM discontinuing oral PrEP.ResultsWe eventually enrolled 6535 participants. Among the 685 participants who had used oral PrEP, 19.70% (135/685) ceased oral PrEP. The results indicated that individuals spending > ¥1000 on a bottle of PrEP (aOR = 2.999, 95% CI: 1.886–4.771) were more likely to cease oral PrEP compared to those spending ≤ ¥1000. Conversely, individuals opting for on-demand PrEP (aOR = 0.307, 95% CI: 0.194–0.485) and those using both daily and on-demand PrEP (aOR = 0.114, 95% CI: 0.058–0.226) were less likely to cease PrEP compared to those using daily PrEP. The qualitative analysis uncovered eight themes influencing oral PrEP cessation: (i) High cost and low adherence; (ii) Sexual inactivity; (iii) Lack of knowledge about PrEP; (iv) Trust in current prevention strategies; (v) Poor quality of medical service and counseling; (vi) PrEP stigma; (vii) Partner and relationship factors; (viii) Access challenges.ConclusionsThe cessation of oral PrEP among MSM in China is associated with various factors, including the cost of oral PrEP medication, regimens, individual perception of HIV risk, stigma, and the quality of medical services. It is recommended to provide appropriate regimens for eligible MSM and develop tailored combinations of strategies to enhance PrEP awareness and acceptance among individuals, medical staff, and the MSM community. The findings from this study can support the refinement of HIV interventions among MSM in China, contributing to efforts to reduce the burden of HIV in this population.

Risk perceptions and experience in child protection decision-making: A comparative study of student social workers in Wales and Aotearoa New Zealand

Decision making in child protection is the product of interacting factors between workers, organizations, families, and macro social structures. Individual perceptions of risk, safety, and harm, as one piece of this complex puzzle, are important to understand. This article reports on a comparative study of social work students in two countries: Wales and Aotearoa New Zealand. Using a mixed methods survey and a staged vignette (in which the situation becomes progressively more serious), we found there were similarities between respondents from the two countries in their perceptions of risk, safety and harm, and their reasoning processes. Beneath this broad consensus, respondents from Wales rated the level of harm to the children lower at earlier stages but were more likely to say the case should meet the threshold for statutory intervention. Risk-averse respondents were more likely to conclude the children experienced serious harm and also that the case should meet the threshold for statutory intervention. These differences largely disappeared by the concluding stage. Qualitative analysis shows that the reasoning processes used to explain risk, safety, and plan goals were similar between the two countries. Some nuanced differences emerged in relation to a risk-averse group fromAotearoa New Zealandemphasizing the importance of continuing engagement with professional services as a sign of change. Implications are discussed, particularly for workforce development and the needs of newly qualified social workers.

The Risk Perception of the Chinese Diaspora during the COVID-19 Pandemic: Targeting Cognitive Dissonance through Storytelling.

The global COVID-19 pandemic in 2020 required risk communications to mitigate the virus' spread. However, social media not only conveyed health information to minimize the contagion, but also distracted from the threat by linking it to an externalized 'other'-primarily those appearing to be of Chinese descent. This disinformation caused the attribution of blame to Chinese people worldwide. In Canada's Greater Toronto Area, Chinese individuals reported widespread public stigma that compounded their risk of contagion; to the degree that it was driven by cognitive dissonance, it generated experiences of social and cultural vulnerability. In this paper, we draw on the aforementioned study's findings to explain how the risk perception and threat appraisal of Chinese diaspora individuals were impacted by different cognitive dissonance pathways. These findings explore how storytelling is a viable intervention with which to target and mitigate cognitive dissonance. Indeed, the mechanisms of cognitive dissonance can modify risk perception and mitigate social and cultural vulnerability, thereby averting potential long-term negative consequences for one's mental health and well-being. We hope our guidance, training educators to target pathways of cognitive dissonance by drawing on storytelling (with humour), can assist them to better convey information in ways that are more inclusive during public health emergencies.

The Risk Perception as a Mediator Between Herding and Overconfidence on Investment Decision by Gen Z in Indonesia

Behavioral finance theory highlights how psychological factors can lead to poor investment decisions, which may threaten investors' trust in the stock market, discourage investments, and hinder economic growth. This study aims to examine how behavioral finance factors, particularly herding bias and overconfidence bias, influence investment decision on the Indonesia Stock Exchange through risk perception. The research was conducted using an online questionnaire distributed to 120 Gen Z stock investors and analyzed using PLS-SEM. The results show that herding and overconfidence biases have a significant positive influence on risk perception. Both herding and overconfidence biases have indirect positive influences on investment decision through risk perception. Although overconfidence bias and risk perception can directly affect investment decision, herding bias fails to do so. These findings highlight the importance of considering an individual's behavioral biases and risk perception, while policymakers should devise strategies to mitigate their impacts; so that investors can benefit from investing, which may eventually lead to the growth of the national economy

Mass evacuation planning for disasters management: A household evacuation route choice behavior analysis

This paper presents a multi-methodological approach to analyzing household evacuation route choice behaviors and the related decision-making for mass evacuation planning in disaster management. Specifically, the proposed multi-methodological approach integrates a syncretic risk perception conceptual model with a household-based group utility evolution model. The dynamics of household evacuation route choice are explored in two stages, namely the individual utility initiation and accommodation. The unique feature of the proposed approach is that it links individual risk perception, survival psychology, and group behavioral dynamics together to characterize household decision-making about choosing the evacuation routes. An empirical study coupled with experiments is conducted to help validate the proposed household evacuation route choice behavior model. Through various designed disaster scenarios, the applicability and strengths of the proposed model for mass evacuation planning and management are demonstrated. Particularly, the mean relative prediction errors of the proposed model with respect to household-based evacuation route switching probability and path flow splits are 3.79% and 6.88%, respectively, all within an acceptable range of ±10 %. This demonstrates that the proposed model and analytical results align closely with household choice behavior.

Multi-information and epidemic coupling propagation considering indirect contact on two-layer networks

This research provides an in-depth examination of the interplay between diverse information propagation and epidemic spread within a two-layer network, placing particular emphasis on the implications of both direct and indirect modes of disease transmission. Individuals are categorized based on their susceptibility to and their capacity for disease propagation, while the influence of varying infection rates on epidemic expansion is investigated. Information is bifurcated into constructive narratives with beneficial outcomes, and detrimental narratives originating from rumors. The method of information dispersion incorporates considerations such as herd behavior, preventative costs, and individual risk perception. Utilizing the Microscopic Markov Chain Approach (MMCA), a dynamic equation is formulated to delineate epidemic propagation and the epidemic threshold for the proposed model is calculated. Results demonstrate that promoting swift dissemination of positive information, concurrently with curbing the spread of negative narratives, can appreciably mitigate epidemic proliferation. The findings also imply that facilitating access to beneficial information, minimizing the consequences of harmful narratives, decreasing prevention-related expenses, and enhancing personal risk perception can significantly reduce the ultimate magnitude of the epidemic. Notably, the study reveals that indirect contact can considerably augment epidemic spread. As the infection rate via indirect contact escalities, the extent of epidemic transmission broadens and the threshold for epidemic transmission diminishes.

How health risk of COVID-19 resurgence may trigger individual tendencies regarding COVID-19-related cyberchondria: Investigating the I-PACE model

Cyberchondria during the COVID-19 pandemic has posed significant challenges to public well-being. Previous lstudies have implicated perceived health risk in COVID-19-related cyberchondria. However, the effect of perceived COVID-19 health risk on cyberchondria and potential underlying mechanisms remains unclear. In this study, we developed a model based on the general addictive behavior framework of the I-PACE (Interaction-Person-Affect-Cognition-Execution) model to describe how induction of health risk of COVID-19 resurgence may influence individual tendencies regarding COVID-19-related cyberchondria. Through a scenario-based experiment, we tested this model with a balanced sample of 984 participants from China. The results revealed that the effect of induction of health risk of COVID-19 resurgence on tendencies regarding COVID-19-related cyberchondria was fully mediated by individual's risk perception and health information craving. Additionally, moderation analysis showed that an individual's general inhibitory control did not moderate the development of cyberchondria. Theoretical and practical implications are provided.

Driving after substance use in Rhode Island adolescents: A cross-sectional analysis of surveillance data

Objective Existing literature on driving under the influence during adolescence is sparse, especially for driving after the use of non-medical prescription drugs (DAP). This study examines the prevalence of driving after use of alcohol (DAA), cannabis (DAC), and DAP, and examines the role of several potential risk and protective factors. Methods This was a secondary analysis of the 2022 Rhode Island Study Survey, a cross-sectional survey of middle and high school students. Separate multivariable regressions were conducted for each outcome among lifetime users for each substance, controlling for current substance use, individual-, perceived parental-, and perceived friend-substance use risk perception, age, sexual/gender minority (SGM) status, race, ethnicity, school level, and town poverty level. Results Among lifetime users of alcohol (n = 3849), cannabis (n = 2289), and non-medical prescription drugs (n = 611), the prevalence of DAA, DAC, and DAP was 4.9, 14.3, and 16.9%, respectively. Current substance use, high individual risk perception, being nonwhite, and being Hispanic were risk factors for DAA while perceiving parent’s risk perception as negative and being heterosexual cisgender-female were protective. Current substance use, negative individual risk perception, and being nonwhite were risk factors for DAC while perceiving parent’s risk perception as negative and being in high school were protective. Current substance use and older age were risk factors for DAP while perceiving parent’s risk perception as negative and perceiving friend’s risk perception as negative were protective. Conclusions Driving under the influence is a concern among adolescent substance users. Current substance use and perceived parental risk perception as negative are common risks and protective factors, respectively. Findings suggest substance-specific, heterogeneous interventions are needed. For example, interventions focusing on peer perceptions are most relevant for DAP, while shifting personal perceptions of harm are most relevant for DAC.

Effects of the Omaha System- and HeartScore®-Based Impaired-Risk Perception Reduction Program on the Risk Perception of Individuals Aged 50-65 Years: A One-Group Pre-Test-Post-Test Study.

This study evaluates the impact of interventions in the Omaha System and HeartScore®-based program to reduce impaired-risk perception. and setting: This study utilized a one-group pre-test-post-test design. The program was conducted among participants aged over 50 years from different social settings. The program had three parts: a briefing on HeartScore® recommendations, Omaha System interventions, and referral to a doctor. HeartScore® determined cardiovascular disease (CVD) risk, body mass index (BMI) was calculated from height and weight, and the International PA Questionnaire evaluated physical activity (PA) levels. Self-assessment was used to perceived CVD risk, BMI, and PA. We used the Wilcoxon signed-rank test to compare the pre-test and post-test scores of the Omaha System, the problem rating scale (PRS) subscales and McNemar test to measure changes in CVD risk perception, BMI, and PA level. 310 high-risk individuals out of 522 had impaired perception of their CVD risk. Only 201 responded to follow-up phone calls. Interventions based on HeartScore® and Omaha System improved CVD risk and PA perceptions (P < .001) but not BMI. The program significantly increased knowledge, status, and behavior scores (P < .001). After participating, 39% saw a cardiologist, and 57.2% saw a family physician within six months to reduce impaired risk perception. CVD risk perception increased to the actual level after the intervention, mostly in the group with low education level. The program using the Omaha System and HeartScore® can help middle-aged individuals better understand their risk of cardiovascular disease.

Exploring the exponential sensitivity of risk perception in the COVID-19 pandemic.

Individual's risk perception regarding specific hazards is a dynamic process that evolves over time. This study analyzed the relationship between the number of COVID-19 cases and the South Korean public's risk perceptions from the outset of the pandemic to the recent past. More than 70 repeated cross-sectional surveys were conducted biweekly to measure individuals' risk perception. An autoregressive integrated moving average with explanatory variable time series analysis was used to characterize the relationship between the number of COVID-19 cases and level of risk perceptions. It revealed that individuals' risk perception and the number of COVID-19 cases were not linearly related but were logarithmically correlated. This finding can be understood as a psychic numbing effect, suggesting that people's perception of risk is not linear but rather exponentially sensitive to changes. The findings also revealed a significant influence of individuals' trust in local governments on their risk perceptions, highlighting the substantial role played by local governments in direct risk management during the COVID-19 pandemic.
