Previous research suggested that illness perceptions provide the basis for illness risk perceptions through an inductive reasoning process. This study aimed to assess the direction of relationships between illness and recurrence risk perceptions over time, among cardiac patients. A longitudinal study was conducted among 138 patients undergoing coronary angioplasty. Self-report questionnaires measured perceived recurrence risk and illness perceptions one day and one month after catheterisation. Cross-lagged Panel Model Analyses revealed that higher perceptions of timeline, consequences and emotional representations of illness at hospitalisation were associated with higher recurrence risk perceptions one month later. Perceived personal control was the only illness perception with bi-directional associations: higher perceived personal control at hospitalisation was associated with higher recurrence risk perceptions one month later; and higher recurrence risk perceptions at hospitalisation was associated with lower personal control one month later. The findings suggest that the associations between recurrence risk and illness perceptions can only partly be explained by inductive reasoning. Halo effects and defensive processes are suggested as complementary explanations for the observed associations between risk and illness perceptions.

Objective This study assesses perceptions of overall harm, short-term health and social risks, long-term health risks, and benefits associated with various tobacco products including conventional cigarettes, e-cigarettes, cigars, chew, and hookah. This study also assesses whether and how perceptions differ by age, gender, race/ethnicity, and previous experience with tobacco. Methods A total of 722 high school students completed an online survey, answering questions about their use and perceptions of a variety of tobacco products. Differences in perceptions across products were assessed using a generalized estimation equation with an exchangeable correlation structure. Results Adolescents rated the various tobacco products as conferring significantly different levels of risks and benefits. Generally, adolescents rated cigarettes as most risky, followed by cigars and chew, with hookah and e-cigarettes rated as least risky. Adolescents rated hookah followed by cigarettes and e-cigarettes as most likely to make them look cool or fit in and cigars and chew as least likely to confer these benefits. There were interaction effects by age and use, with older adolescents and those with tobacco experience holding lower perceptions of risk. There were no significant interaction effects by race/ethnicity or gender. Conclusion Given the significant differences in adolescents’ perceptions of risks and benefits of using different tobacco products and research showing the predictive relationship between perceptions and behavior, there is a need for comprehensive messaging that discusses risks of all tobacco products, particularly hookah and e-cigarettes. There is also a need to address perceived benefits of tobacco products, especially hookah and e-cigarettes. PMID:27107909

Rural Nevada and climate change: vulnerability, beliefs, and risk perception.

In this article, we present the results of a study investigating the influence of vulnerability to climate change as a function of physical vulnerability, sensitivity, and adaptive capacity on climate change risk perception. In 2008/2009, we surveyed Nevada ranchers and farmers to assess their climate change-related beliefs, and risk perceptions, political orientations, and socioeconomic characteristics. Ranchers' and farmers' sensitivity to climate change was measured through estimating the proportion of their household income originating from highly scarce water-dependent agriculture to the total income. Adaptive capacity was measured as a combination of the Social Status Index and the Poverty Index. Utilizing water availability and use, and population distribution GIS databases; we assessed water resource vulnerability in Nevada by zip code as an indicator of physical vulnerability to climate change. We performed correlation tests and multiple regression analyses to examine the impact of vulnerability and its three distinct components on risk perception. We find that vulnerability is not a significant determinant of risk perception. Physical vulnerability alone also does not impact risk perception. Both sensitivity and adaptive capacity increase risk perception. While age is not a significant determinant of it, gender plays an important role in shaping risk perception. Yet, general beliefs such as political orientations and climate change-specific beliefs such as believing in the anthropogenic causes of climate change and connecting the locally observed impacts (in this case drought) to climate change are the most prominent determinants of risk perception. © 2012 Society for Risk Analysis.

Risk calculators are popular websites that provide individualized disease risk assessments to the public. Little is known about their effect on risk perceptions and health behavior. This study sought to test whether risk calculator features-namely, personalized estimates of one's disease risk and feedback about the effects of risk-mitigating behaviors-improve risk perceptions and motivate healthy behavior. A web-based experimental study using simple randomization was conducted to compare the effects of 3 prediabetes risk communication websites. Setting The study was conducted in the context of ongoing health promotion activities sponsored by a university's human resources office. Patients Participants were adult university employees. Intervention The control website presented nonindividualized risk information. The personalized noninteractive website presented individualized risk calculations. The personalized interactive website presented individualized risk calculations and feedback about the effects of hypothetical risk-mitigating behaviors. Measurements Pre- and postintervention risk perceptions were measured in absolute and relative terms. Health behavior was measured by assessing participant interest in follow-up preventive health services. On average, risk perceptions decreased by 2%. There was no general effect of personalization or interactivity in aligning subjective risk perceptions with objective risk calculations or in increasing healthy behaviors. However, participants who previously overestimated their risk reduced their perceptions by 16%. This was a significantly larger change than the 2% increase by participants who underestimated their risk. Limitations Results may not generalize to different populations, different diseases, or longer-term outcomes. Compared to nonpersonalized information, individualized risk calculators had little positive effect on prediabetes risk perception accuracy or health behavior. Risk perception accuracy was improved in people who receive relatively "good news" about risk rather than "bad news."

Medical decisions made on behalf of another person-particularly those made by adult caregivers for their minor children-are often informed by the decision maker's beliefs about the treatment's risks and benefits. However, we know little about the cognitive and affective mechanisms influencing such "proxy" risk perceptions and about how proxy risk perceptions are related to prominent judgment phenomena. Adult caregivers of minor children with asthma ( N = 132) completed an online, cross-sectional survey assessing 1) cognitions and affects that form the basis of the availability, representativeness, and affect heuristics; 2) endorsement of the absent-exempt and the better-than-average effect; and 3) proxy perceived risk and unrealistic comparative optimism of an asthma exacerbation. We used the Pediatric Asthma Control and Communication Instrument (PACCI) to assess asthma severity. Respondents with higher scores on availability, representativeness, and negative affect indicated higher proxy risk perceptions and (for representativeness only) lower unrealistic optimism, irrespective of asthma severity. Conversely, respondents who showed a stronger display of the better-than-average effect indicated lower proxy risk perceptions but did not differ in unrealistic optimism. The absent-exempt effect was unrelated to proxy risk perceptions and unrealistic optimism. Heuristic judgment processes appear to contribute to caregivers' proxy risk perceptions of their child's asthma exacerbation risk. Moreover, the display of other, possibly erroneous, judgment phenomena is associated with lower caregiver risk perceptions. Designing interventions that target these mechanisms may help caregivers work with their children to reduce exacerbation risk.

Although risk perception is a key predictor in health behavior theories, current conceptions of risk comprise only one (deliberative) or two (deliberative vs. affective/experiential) dimensions. This research tested a tripartite model that distinguishes among deliberative, affective, and experiential components of risk perception. In two studies, and in relation to three common diseases (cancer, heart disease, diabetes), we used confirmatory factor analyses to examine the factor structure of the tripartite risk perception (TRIRISK) model and compared the fit of the TRIRISK model to dual-factor and single-factor models. In a third study, we assessed concurrent validity by examining the impact of cancer diagnosis on (a) levels of deliberative, affective, and experiential risk perception, and (b) the strength of relations among risk components, and tested predictive validity by assessing relations with behavioral intentions to prevent cancer. The tripartite factor structure was supported, producing better model fit across diseases (studies 1 and 2). Inter-correlations among the components were significantly smaller among participants who had been diagnosed with cancer, suggesting that affected populations make finer-grained distinctions among risk perceptions (study 3). Moreover, all three risk perception components predicted unique variance in intentions to engage in preventive behavior (study 3). The TRIRISK model offers both a novel conceptualization of health-related risk perceptions, and new measures that enhance predictive validity beyond that engendered by unidimensional and bidimensional models. The present findings have implications for the ways in which risk perceptions are targeted in health behavior change interventions, health communications, and decision aids.

The relation between risk perceptions and physical activity among older adults: a prospective study.

Past studies have found that risk perceptions of suffering from diseases play an important role in the development of intentions to perform physical activity (PA). According to the behaviour motivation hypothesis, perceived risk could be positively and directly related to PA, but this possibility has been ignored and/or underestimated. Accounting for recent methodological developments on the importance of study design and risk perception assessment, the purpose of the present study was to examine the risk-perceptions-PA relationship among older adults. Participants (N=143) aged from 61 to 70 years initially underwent measurement of risk perceptions, baseline PA, socio-demographic and health factors. Six months later, they were asked about their PA participation. Multiple regression analyses revealed that perceived risk of suffering from diseases and conditions without regular PA participation was an independent positive predictor of later PA, over and beyond baseline behaviour, socio-demographic and health variables. This study fills a gap in the existing literature on the PAs of older adults and reveals that risk perceptions are directly linked to their participation. In addition, it extends existing knowledge in health psychology on the behaviour motivation hypothesis, and emphasises the necessity of methodological adjustments when assessing the risk-perception-behaviour relationship. © 2011 Taylor & Francis

Service users' self-perception of risk has rarely been emphasized in violence risk assessments. A recent review pointed to the importance of a multidisciplinary approach, because different perspectives may provide a deeper and improved understanding of risk assessment. The aim of this study was to investigate service users' perceptions of their own risk of committing violence, using a self-report risk scale, to determine the feasibility and efficacy of this potential violence risk marker during acute mental health hospitalization. All service users admitted to a psychiatric emergency hospital in Norway during one calendar year were included (N = 512). Nearly 80% self-reported no risk or low risk; only seven (1.4%) reported moderate risk or high risk. Service users who reported moderate risk, high risk, don't know, or won't answer were more likely to be violent (OR = 4.65, 95% CI = 2.79-7.74) compared with those who reported no risk or low risk. There was a significant gender interaction with higher OR for women on both univariate and multivariate analyses. Although the OR was higher for women, women's violence rate (11.0%) was almost half that of men (21.8%). For women, sensitivity and specificity were 0.55 and 0.88, respectively; corresponding values for men were 0.40 and 0.80. Inclusion of self-perception of violence risk is the first step towards service users' collaborative involvement in violence prediction; these results indicate that self-perception can contribute to violence risk assessments in acute mental health settings. Findings also indicate that there are gender differences in these assessments. © 2017 Australian College of Mental Health Nurses Inc.

Integrating public risk perception into formal natural hazard risk assessment

Plattner, Th.; Plapp, T.; Hebel, B.

2006-06-01

An urgent need to take perception into account for risk assessment has been pointed out by relevant literature, its impact in terms of risk-related behaviour by individuals is obvious. This study represents an effort to overcome the broadly discussed question of whether risk perception is quantifiable or not by proposing a still simple but applicable methodology. A novel approach is elaborated to obtain a more accurate and comprehensive quantification of risk in comparison to present formal risk evaluation practice. A consideration of relevant factors enables a explicit quantification of individual risk perception and evaluation. The model approach integrates the effective individual risk reff and a weighted mean of relevant perception affecting factors PAF. The relevant PAF cover voluntariness of risk-taking, individual reducibility of risk, knowledge and experience, endangerment, subjective damage rating and subjective recurrence frequency perception. The approach assigns an individual weight to each PAF to represent its impact magnitude. The quantification of these weights is target-group-dependent (e.g. experts, laypersons) and may be effected by psychometric methods. The novel approach is subject to a plausibility check using data from an expert-workshop. A first model application is conducted by means of data of an empirical risk perception study in Western Germany to deduce PAF and weight quantification as well as to confirm and evaluate model applicbility and flexibility. Main fields of application will be a quantification of risk perception by individual persons in a formal and technical way e.g. for the purpose of risk communication issues in illustrating differing perspectives of experts and non-experts. For decision making processes this model will have to be applied with caution, since it is by definition not designed to quantify risk acceptance or risk evaluation. The approach may well explain how risk perception differs, but not why it differs. The formal model generates only "snap shots" and considers neither the socio-cultural nor the historical context of risk perception, since it is a highly individualistic and non-contextual approach.

The aim of this study was to compare the different approaches used for chemical risk assessment, in relation to the perception of riskfor operators, in some research laboratories of a hospital in Rome. All information regarding the chemicals used for the application of three algorithmic models for chemical risk assessment ("Movarisch", "Inforisk", "Archimede") were collected. An environmental and biological monitoring and a study on the combined exposure to multiple chemicals using the World Health Organization proposed steps were carried out. A questionnaire was prepared for the identification of risk perception. An estimation of chemical risk with algorithms was compared with data from monitoring: findings showed that estimated risk was higher than those identified with airborne or urine concentrations, always under their limit values. The study of multiple exposure showed a possible cumulative risk, in some cases, but the conditions of use (volume and time) often bring to a reduced one. The perception of risk attributed to the monitored hazardous substances showed a correct perception in all laboratories and for all workers, with regard to the substances manipulated.

Thinking through cancer risk: characterizing smokers' process of risk determination.

Hay, Jennifer; Shuk, Elyse; Cruz, Gustavo; Ostroff, Jamie

The perception of cancer risk motivates cancer risk reduction behaviors. However, common measurement strategies for cancer risk perceptions, which involve numerical likelihood estimates, do not adequately capture individuals' thoughts and feelings about cancer risk. To guide the development of novel measurement strategies, the authors used semistructured interviews to examine the thought processes used by smokers (N = 15) as they considered their cancer risk. They used grounded theory to guide systematic data coding and develop a heuristic model describing smokers' risk perception process that includes a cognitive, primarily rational process whereby salient personal risk factors for cancer are considered and combined, and an affective/attitudinal process, which shifts risk perceptions either up or down. The model provides a tentative explanation concerning how people hold cancer risk perceptions that diverge from rational assessment of their risks and will be useful in guiding the development of non-numerical measurements strategies for cancer risk perceptions.

Risk perception is a subjective assessment of the actual or potential threat to one's life or, more broadly, to one's psychological well-being. Given the various risks associated with later life, a valid and reliable integrative screening tool for assessing risk perception among the elderly is warranted. The study examined the psychometric properties and factor structure of a new integrative risk perception instrument, the Perceived Risk Scale. This eight-item measure refers to various risks simultaneously, including terror, health issues, traffic accidents, violence, and financial loss, and was developed specifically for older adults. An online survey was conducted with 306 participants aged 50 years and older. The scale was examined using exploratory factor analysis and concurrent validity testing. Factor analysis revealed a two-factor structure: later-life risks and terror risks A high percentage of explained variance, as well as internal consistency, was found for the entire scale and for both factors. Concurrent validity was supported by significant positive associations with participants' depression and negative correlations with their life satisfaction. These findings suggest that the Perceived Risk Scale is internally reliable, valid, and appropriate for evaluating risk perception in later life. The scale's potential applications are discussed. © The Author(s) 2016.

"OBJECTIVES: to identify groups of people in relation to the perception of environmental risk and to assess the main characteristics using data collected in the environmental module of the surveillance network Italian Behavioral Risk Factor Surveillance System (PASSI). perceptive profiles were identified using a latent class analysis; later they were included as outcome in multinomial logistic regression models to assess the association between environmental risk perception and demographic, health, socio-economic and behavioural variables. the latent class analysis allowed to split the sample in "worried", "indifferent", and "positive" people. The multinomial logistic regression model showed that the "worried" profile typically includes people of Italian nationality, living in highly urbanized areas, with a high level of education, and with economic difficulties; they pay special attention to their own health and fitness, but they have a negative perception of their own psychophysical state. the application of advanced statistical analysis enable to appraise PASSI data in order to characterize the perception of environmental risk, making the planning of interventions related to risk communication possible.

Clinical decision support provided by drug information centers is an intervention that can ensure rational drug therapy for pregnant women. We have examined whether physicians' teratogenic risk perceptions and confidence in prescribing drugs to pregnant women is altered after advice from the Norwegian drug information centers, Regional Medicines and Pharmacovigilance Centres i Norway (RELIS). Physicians who consulted RELIS for advice on patient-specific drug use in pregnancy from November 2013 to April 2014 completed questionnaires before and after receiving the advice. A scale from 1 to 7 was used to rate confidence in prescribing and perception of teratogenic risk. The lower part of the scale represented a low perception of teratogenic risk and a high confidence in prescribing a drug in pregnancy. The data were analyzed using a mixed linear model. A total of 45 physicians participated in the study and they assessed 64 drugs or categories of drugs. Advice from RELIS increased confidence in prescribing, with a statistically significant mean change on the scale from 4.1 to 2.9. The assessment of teratogenic risk was reduced after advice from RELIS, with a mean change from 3.2 to 2.5, though this was not significant. A subgroup of 26 physicians completed questionnaires both before and after advice from RELIS and assessed a total of 32 drugs or categories of drugs. In 94% of these assessments, advice from RELIS altered the physician's confidence in prescribing. Perception of teratogenic risk was altered in 78% of the assessments. Our results show that physicians' perception of teratogenic risk and confidence in prescribing drugs to pregnant women is influenced by advice from Norwegian drug information centers.

Worldwide, more than 50 million cases of dengue fever are reported every year in at least 124 countries, and it is estimated that approximately 2.5 billion people are at risk for dengue infection. In Bangladesh, the recurrence of dengue has become a growing public health threat. Notably, knowledge and perceptions of dengue disease risk, particularly among the public, are not well understood. Recognizing the importance of assessing risk perception, we adopted a comparative approach to examine a generic methodology to assess diverse sets of beliefs related to dengue disease risk. Our study mapped existing knowledge structures regarding the risk associated with dengue virus, its vector (Aedes mosquitoes), water container use, and human activities in the city of Dhaka, Bangladesh. "Public mental models" were developed from interviews and focus group discussions with diverse community groups; "expert mental models" were formulated based on open-ended discussions with experts in the pertinent fields. A comparative assessment of the public's and experts' knowledge and perception of dengue disease risk has revealed significant gaps in the perception of: (a) disease risk indicators and measurements; (b) disease severity; (c) control of disease spread; and (d) the institutions responsible for intervention. This assessment further identifies misconceptions in public perception regarding: (a) causes of dengue disease; (b) dengue disease symptoms; (c) dengue disease severity; (d) dengue vector ecology; and (e) dengue disease transmission. Based on these results, recommendations are put forward for improving communication of dengue risk and practicing local community engagement and knowledge enhancement in Bangladesh. © 2015 Society for Risk Analysis.

Clinical risk stratification models, such as the CHA2DS2-VASc, are used to assess stroke risk in atrial fibrillation (AF) patients. No study has yet investigated whether and to which extent these patients have a realistic perception of their personal stroke risk. The purpose of this study was to investigate and describe the association between AF patients' stroke risk perception and clinical stroke risk. In an observational cross-sectional study design, we surveyed 178 AF patients with a mean age of 70.6 years (SD 8.3) in stable anticoagulant treatment (65% treatment duration >12 months). Clinical stroke risk was scored through the CHA2DS2-VASc, and patients rated their perceived personal stroke risk on a 7-point Likert scale. There was no significant association between clinical stroke risk assessment and patients' stroke risk perception (rho = .025; P = .741). Approximately 60% of the high-risk patients had an unrealistic perception of their own stroke risk, and there was no significant increase in risk perception from those with a lower compared with a higher risk factor load (χ(2) = .010; P = .522). Considering possible negative implications in terms of lack of motivation for lifestyle behavior change and adequate adherence to the treatment and monitoring of vitamin K antagonist, the apparent underestimation of risk by large subgroups warrants attention and needs further investigation with regard to possible behavioral consequences.

Background: The increase in breast cancer incidence has enhanced attention towards breast cancer risk. The aim of this study was to determine the risk of breast cancer and risk perception of women, factors that affect risk perception, and to determine differences between absolute risk and the perception of risk. Methods: This cross-sectional study was carried out among 346 women whose score in the Gail Risk Model (GRM) was ≥ 1.67% and/or had a 1st degree relative with breast cancer in Bahçeşehir town in Istanbul, Turkey between Jul 2012 and Dec 2012. Data were collected through face-to-face interviews. The level of risk for breast cancer has been calculated using GRM and the Breast Cancer Risk Assessment Form (BCRAF). Breast cancer risk perception (BCRP), has been evaluated by visual analogue 100-cm-long scale. Results: Even though 39.6% of the women considered themselves as high-risk carriers, according to the GRM and the BCRAF, only 11.6% and 9.8% of women were in the “high risk” category, respectively. There was a positive significant correlation between the GRM and the BCRAF scores (P<0.001), and the BCRAF and BCRP scores (P<0.001). Factors related to high-risk perception were age (40–59 yr), post-menopausal phase, high-very high economic income level, existence of breast cancer in the family, having regular breast self-examination and clinical breast examination (P<0.05). Conclusion: In women with high risk of breast, cancer there is a significant difference between the women’s risk perception and their absolute risk level. PMID:28435816

Background There is a high incidence of adverse effects from non-steroidal antiinflammatory drugs (NSAIDs) in Thailand, but patients' perceptions and knowledge of NSAID risks is unknown. Objective This study aims to assess patients' perceptions and knowledge of NSAID risks and factors affecting them. Setting University hospital in North-East of Thailand. Method A Cross-sectional study conducted over 4 months, using a self-administered questionnaire. Patients prescribed NSAIDs for at least one month duration from orthopaedic clinic were recruited using systematic random sampling. Main outcome measure Patients' perceptions on NSAID risks, knowledge on risk factors, and their associated factors. Results A total of 474 questionnaires were assessed. Overall perceptions of risks was low (scoring below five on a 0-10 visual analogue scale), with risks associated with the renal system scoring highest. Perceived risk of gastrointestinal problems differed between patients using non-selective and selective NSAIDs (3.47 ± 2.75 vs 2.06 ± 2.98; P < 0.001). Receiving side effect information from a health professional was associated with higher risk perception. Most patients (80 %) identified high doses, renal disease and gastrointestinal ulcer increased risks of NSAIDs, but fewer than half recognized that use in the elderly, multiple NSAID use, drinking, hypertension and cardiovascular disease also increased risk of adverse events. Having underlying diseases and receiving side effect information were associated with 1.6-2.0 fold increased knowledge of NSAID risks. Conclusion Perceptions and knowledge concerning NSAID risks was generally low in Thai patients, but higher in those who had received side effect information. Risk-related information should be widely provided, especially in high-risk patients.

The essential characteristics of the issue of radioactive waste management can be conceptualized as complex, with a variety of facets and uncertainty. These characteristics tend to cause people to perceive the issue of radioactive waste management as a 'risk'. This study was initiated in response to a desire to understand the perceptions of risk that the Korean public holds towards radioactive waste and the relevant policies and policy-making processes. The study further attempts to identify the factors influencing risk perceptions and the relationships between risk perception and social acceptance.

Stakeholder Perceptions of Risk in Construction.

2016-02-01

Safety management in construction is an integral effort and its success requires inputs from all stakeholders across design and construction phases. Effective risk mitigation relies on the concordance of all stakeholders' risk perceptions. Many researchers have noticed the discordance of risk perceptions among critical stakeholders in safe construction work, however few have provided quantifiable evidence describing them. In an effort to fill this perception gap, this research performs an experiment that investigates stakeholder perceptions of risk in construction. Data analysis confirms the existence of such discordance, and indicates a trend in risk likelihood estimation. With risk perceptions from low to high, the stakeholders are architects, contractors/safety professionals, and engineers. Including prior studies, results also suggest that designers have improved their knowledge in building construction safety, but compared to builders they present more difficultly in reaching a consensus of perception. Findings of this research are intended to be used by risk management and decision makers to reassess stakeholders' varying judgments when considering injury prevention and hazard assessment.

Safety management in construction is an integral effort and its success requires inputs from all stakeholders across design and construction phases. Effective risk mitigation relies on the concordance of all stakeholders’ risk perceptions. Many researchers have noticed the discordance of risk perceptions among critical stakeholders in safe construction work, however few have provided quantifiable evidence describing them. In an effort to fill this perception gap, this research performs an experiment that investigates stakeholder perceptions of risk in construction. Data analysis confirms the existence of such discordance, and indicates a trend in risk likelihood estimation. With risk perceptions from low to high, the stakeholders are architects, contractors/safety professionals, and engineers. Including prior studies, results also suggest that designers have improved their knowledge in building construction safety, but compared to builders they present more difficultly in reaching a consensus of perception. Findings of this research are intended to be used by risk management and decision makers to reassess stakeholders’ varying judgments when considering injury prevention and hazard assessment.

Background It has been found that health-seeking behavior has a certain impact on influenza infection. However, behaviors with/without risk perception on the control of influenza transmission among age groups have not been well quantified. Objectives The purpose of this study was to assess to what extent, under scenarios of with/without control and preventive/protective behaviors, the age-specific network-driven risk perception influences influenza infection. Materials and methods A behavior-influenza model was used to estimate the spread rate of age-specific risk perception in response to an influenza outbreak. A network-based information model was used to assess the effect of network-driven risk perception information transmission on influenza infection. A probabilistic risk model was used to assess the infection risk effect of risk perception with a health behavior change. Results The age-specific overlapping percentage was estimated to be 40%–43%, 55%–60%, and 19%–35% for child, teenage and adult, and elderly age groups, respectively. Individuals perceive the preventive behavior to improve risk perception information transmission among teenage and adult and elderly age groups, but not in the child age group. The population with perceived health behaviors could not effectively decrease the percentage of infection risk in the child age group, whereas for the elderly age group, the percentage of decrease in infection risk was more significant, with a 97.5th percentile estimate of 97%. Conclusion The present integrated behavior-infection model can help health authorities in communicating health messages for an intertwined belief network in which health-seeking behavior plays a key role in controlling influenza infection.

Cancer risk elicitation and communication: lessons from the psychology of risk perception.

PubMed

Klein, William M P; Stefanek, Michael E

2007-01-01

Cancer risk perceptions are a key predictor of risk-reduction practices, health behaviors, and processing of cancer information. Nevertheless, patients and the general public (as well as health care providers) exhibit a number of errors and biases in the way they think about risk, such that their risk perceptions and decisions deviate greatly from those prescribed by normative decision models and by experts in risk assessment. For example, people are more likely to engage in screening behaviors such as mammography when faced with loss-based messages than gain-framed messages, and they often ignore the base rate of a given disease when assessing their own risk of obtaining this disease. In this article, we review many of the psychological processes that underlie risk perception and discuss how these processes lead to such deviations. Among these processes are difficulties with use of numerical information (innumeracy), cognitive processes (eg, use of time-saving heuristics), motivational factors (eg, loss and regret aversion), and emotion. We conclude with suggestions for future research in the area, as well as implications for improving the elicitation and communication of personal cancer risk.

To assess perceptions of personnel working at a veterinary teaching hospital regarding risks of occupational hazards and compare those perceptions with assessments made by occupational safety experts. Cross-sectional study. A representative sample of personnel (n = 90) working at the veterinary teaching hospital at Colorado State University and a panel of 3 occupational safety experts. Hospital personnel ranked perceptions of 14 physical, chemical, and biological workplace hazards and listed the injuries, illnesses, and near misses they had experienced. The expert panel provided consensus rankings of the same 14 hazards for 9 sections of the facility. Risk perceptions provided by the 2 sources were compared. Risk perceptions did not differ significantly between hospital personnel and the expert panel for most of the site-specific comparisons (94/126 [75%]). Personnel perceived greater risks for some physical hazards (loud noises, sharps injuries, and ionizing radiation) and some chemical or materials exposures (insecticides or pesticides and tissue digester emissions). In contrast, the expert panel perceived greater risks for physical hazards (bite or crush and restraining and moving animals), chemical exposures (anesthetic waste gas), and biological exposures (Toxoplasma gondii, antimicrobial-resistant bacteria, and allergens). Participants and safety experts had similar perceptions about occupational risks, but there were important differences where hospital personnel apparently overestimated or underappreciated the risks for workplace hazards. This type of study may be useful in guiding development of optimal workplace safety programs for veterinary hospitals.

Objectives Adapt an established instrument for measuring adolescents’ cigarette-related perceptions for new application with electronic cigarettes (e-cigarettes). Methods In this exploratory study, 104 male high school students (40% tobacco ever-users) estimated the probability of potential e-cigarette risks (eg, lung cancer) or benefits (eg, look cool). We calculated associations between risk/benefit composite scores, ever-use, and use intention for e-cigarettes and analogously for combustible cigarettes. Results E-cigarette ever-use was associated with lower perceived risks, with adjusted differences versus never-users greater for e-cigarettes than cigarettes. Risk composite score was inversely associated, and benefit score positively associated, with e-cigarette ever-use and use intention. Conclusion Conditional risk assessment characterized adolescents’ perceived e-cigarette risk/benefit profile, with potential utility for risk-perception measurement in larger future studies.

Effect of sexual motivation on men's risk perception for sexually transmitted disease: there must be 50 ways to justify a lover.

Blanton, H; Gerrard, M

1997-07-01

Recent research has incorporated situational factors into assessment of risk. Working from a rational appraisal framework, however, these studies have not emphasized contextual features that might introduce motivated risk assessment. In the current study, participants (N = 40 male undergraduates) lowered their risk perceptions for STDs following the induction of a sexual motivation. In an initial baseline condition, participants estimated the risk of contracting STDs from partners with relatively high- or low-risk sexual histories. In a subsequent trial, participants repeated the imagery task while viewing photographs that were high or low in sex appeal. As predicted, participants reduced their risk perceptions when they viewed photographs high in sex appeal. The only necessary precondition was the presence of nondiagnostic information from which they could construct biased risk estimates.

Do we see how they perceive risk? An integrated analysis of risk perception and its effect on workplace safety behavior.

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

This report describes the results of a set of five surveys designed to assess the perceived risks of nuclear waste management policy in Colorado and New Mexico. Within these states, mail surveys of randomly selected samples were taken of members of the American Association for the Advancement of Science, members of the Sierra Club, members of business associations, and state legislators. In addition, a telephone sample of randomly selected households was conducted in Colorado and New Mexico. Using these data, the perceptions of the risk of nuclear waste management -- from production of nuclear energy through permanent storage of nuclearmore » wastes -- are compared for each of the five samples. The degree of trust in, and the perceived political influence of, the more prominent policy actors are assessed. Certain cognitive attributes, including degree of subjective certainty regarding beliefs about risks of nuclear wastes, and likelihood of altering perceived risks when confronted with new information, are compared across samples. In addition, the sample scores from rudimentary knowledge tests about the characteristics of radiation are compared. The relationships among the knowledge scores, cognitive attributes and risk perceptions are evaluated. Perceptions of the balance of media coverage are measured, as are the possible direct and indirect roles of media exposure in risk perception. Aggregate models, testing an array of hypotheses about the bases of nuclear waste risk perceptions, are conducted. These tests indicate that risk perceptions are related to a complex set of factors, and that these factors may differ significantly across the different sub-populations. Finally, the relationships between risk perception and political participation -- including registering to vote, political party affiliation, and level of political activism -- are analyzed. 5 figs., 33 tabs.« less

2007-01-01

Background Subjective risk factor perception is an important component of the motivation to change unhealthy life styles. While prior studies assessed cardiovascular risk factor knowledge, little is known about determinants of the individual perception of stroke risk. Methods Survey by mailed questionnaire among 1483 participants of a prior public stroke campaign in Germany. Participants had been informed about their individual stroke risk based on the Framingham stroke risk score. Stroke risk factor knowledge, perception of lifetime stroke risk and risk factor status were included in the questionnaire, and the determinants of good risk factor knowledge and high stroke risk perception were identified using logistic regression models. Results Overall stroke risk factor knowledge was good with 67–96% of the participants recognizing established risk factors. The two exceptions were diabetes (recognized by 49%) and myocardial infarction (57%). Knowledge of a specific factor was superior among those affected by it. 13% of all participants considered themselves of having a high stroke risk, 55% indicated a moderate risk. All major risk factors contributed significantly to the perception of being at high stroke risk, but the effects of age, sex and education were non-significant. Poor self-rated health was additionally associated with high individual stroke risk perception. Conclusion Stroke risk factor knowledge was high in this study. The self perception of an increased stroke risk was associated with established risk factors as well as low perception of general health. PMID:17371603

2016-12-01

The agricultural and forestry sectors in the state of Indiana are highly dependent on climate and, subsequently, highly vulnerable to the impacts of climate change. Higher temperatures, shifts in precipitation patterns, more widespread prevalence of pests and pathogens, and increased frequency and severity of extreme weather events could all have negative effects on these two sectors in the future. Agricultural and forest producers are already modifying their management strategies in response to perceptions of changes in climate risk, but such responses have been primarily reactive in nature and, in many cases, demonstrate a disconnect between scientific findings and stakeholder perceptions of the greatest climate risks. This research has been conducted to help improve understanding of climate change risks to agriculture and forestry in Indiana; stakeholder perceptions of climate risks and their current management strategies; and the effectiveness of these management strategies for dealing with current and future climate risk. Sector-specific focus groups, expert panel assessments and surveys have all been utilized in this work, which will also contribute to the new Indiana Climate Change Impacts Assessment report.

Effect of Gun Carrying on Perceptions of Risk Among Adolescent Offenders.

2016-02-01

We observed how perceptions of risks, costs, crime rewards, and violence exposure change as individual gun-carrying behavior changes among high-risk adolescents. We analyzed a longitudinal study (2000-2010) of serious juvenile offenders in Maricopa County, Arizona, or Philadelphia County, Pennsylvania, assessing within-person changes in risk and reward perceptions, and violence exposure as individuals initiated or ceased gun carrying. Despite being associated with heightened exposure to violence, gun carrying was linked to lower perceptions of risks and costs and higher perceived rewards of offending. Gun carrying was not time-stable, as certain individuals both started and stopped carrying during the study. Within-person changes in carrying guns were associated with shifting perceptions of risks, costs, and rewards of crime, and changes in exposure to violence in expected directions. Gun carrying reduces perceptions of risks associated with offending while increasing actual risk of violence exposure. This suggests that there is an important disconnect between perceptions and objective levels of safety among high-risk youths. Gun-carrying decisions may not only be influenced by factors of protection and self-defense, but also by perceptions of risks and reward associated with engaging in crime more generally.

Adolescent girls and young women (AGYW) in sub-Saharan Africa have high HIV prevalence and incidence. We sought to understand which HIV risk factors individually and in combination contribute to risk, and whether these factors are associated with HIV worry and risk perception. This study is ongoing at 4 public health centers in Lilongwe, Malawi (2016-2017). AGYW of 15-24 years old were recruited to participate in a study assessing 4 models of service delivery. At each health center, participants completed a baseline survey assessing socioeconomic, behavioral, biomedical, and partnership characteristics; self-reported HIV status; and, if HIV-uninfected, HIV risk perception (high versus low or none) and HIV worry (any versus none). We analyzed associations between baseline characteristics and HIV prevalence, risk perception, and worry. Among 1000 AGYW, median age was 19 years (IQR: 17-21). Thirty-three participants reported being HIV-infected. Fifteen characteristics were associated with HIV infection. Having more risk factors was associated with higher HIV prevalence (≤4 factors, 0.5%; 5-8 factors, 6%; >8 factors, 21%). Having more risk factors was also associated with higher risk perception (P < 0.001) and higher worry (P < 0.001). However, among those with ≥8 risk factors, 52% did not consider themselves to be at high risk and 21% did not report any HIV worry. Most AGYW perceive little risk of HIV acquisition, even those at highest risk. As a critical gap in the HIV prevention cascade, accurate risk perception is needed to tailor effective and sustained combination prevention strategies for this vulnerable population.

The Moderating Effect of Mental Toughness: Perception of Risk and Belief in the Paranormal.

Drinkwater, Kenneth; Dagnall, Neil; Denovan, Andrew; Parker, Andrew

2018-01-01

This research demonstrates that higher levels of mental toughness provide cognitive-perceptual processing advantages when evaluating risk. No previous research, however, has examined mental toughness in relation to perception of risk and paranormal belief (a variable associated with distorted perception of causality and elevated levels of perceived risk). Accordingly, the present paper investigated relationships between these factors. A sample of 174 participants completed self-report measures assessing mental toughness, general perception of risk, and paranormal belief. Responses were analyzed via correlations and moderation analyses. Results revealed that mental toughness correlated negatively with perception of risk and paranormal belief, whereas paranormal belief correlated positively with perception of risk. For the moderation effects, simple slopes analyses indicated that high levels of MT and subfactors of commitment and confidence reduced the strength of association between paranormal belief and perceived risk. Therefore, MT potentially acts as a protective factor among individuals who believe in the paranormal, reducing the tendency to perceive elevated levels of risk.

Mapping spatial patterns of people's risk perception of landslides

The resilience of communities against natural hazards is largely influenced by how the individuals perceive risk. A good understanding of people's risk perception, awareness and hazard knowledge is crucial for developing and improving risk management and communication strategies between authorities and the affected population. A lot of research has been done in investigating the social aspects of risks to natural hazards by means of interviews or questionnaires. However, there is still a lack of research in the investigation of the influence of the spatial distance to a hazard event on peoples risk perception. While the spatial dimension of a natural hazard event is always assessed in works with a natural science approach, it is often neglected in works on social aspects of natural hazards. In the present study, we aimed to overcome these gaps by combining methods from different disciplines and assessing and mapping the spatial pattern of risk perception through multivariate statistical approaches based on empirical data from questionnaires. We will present results from a case study carried out in Badia, located in the Province of South Tyrol- Italy, where in December 2012 a landslide destroyed four residential buildings and led to the evacuation of 36 people. By means of questionnaires distributed to all adults living in the case study area we assessed people's risk perception and asked respondents to allocate their place of residence on a map of the case study area subdivided in 7 zones. Based on the data of the questionnaire results we developed a risk perception factor in order to express various assessed aspects linked to risk perception with one metric. We analyzed and mapped this factor according to the different zones reflecting the spatial distance to the event. Furthermore, a cluster analysis identified various risk behavior profiles within the population. We also investigated the spatial patterns of these risk profiles. We revealed that the residential zone in the immediate proximity to the landslide event showed significantly different results than all other zones. Though we have been able to observe spatial patterns of our developed metrics that changed significantly with geographic distance, our results led to the assumption that risk perception cannot be expressed in units of length. The appropriate spatial unit rather seems to be "immediate proximity" to the event. The results of our study can support response forces and authorities in planning and adopting different communication and management strategies tailored to different groups of affected persons.

The function of credibility in information processing for risk perception.

PubMed

Trumbo, Craig W; McComas, Katherine A

2003-04-01

This study examines how credibility affects the way people process information and how they subsequently perceive risk. Three conceptual areas are brought together in this analysis: the psychometric model of risk perception, Eagly and Chaiken's heuristic-systematic information processing model, and Meyer's credibility index. Data come from a study of risk communication in the circumstance of state health department investigations of suspected cancer clusters (five cases, N = 696). Credibility is assessed for three information sources: state health departments, citizen groups, and industries involved in each case. Higher credibility for industry and the state directly predicts lower risk perception, whereas high credibility for citizen groups predicts greater risk perception. A path model shows that perceiving high credibility for industry and state-and perceiving low credibility for citizen groups-promotes heuristic processing, which in turn is a strong predictor of lower risk perception. Alternately, perceiving industry and the state to have low credibility also promotes greater systematic processing, which consistently leads to perception of greater risk. Between a one-fifth and one-third of the effect of credibility on risk perception is shown to be indirectly transmitted through information processing.

Background Studies of posttraumatic stress disorder (PTSD) are mainly focused on victims of trauma. Very few studies explored the links between PTSD symptoms and re-offending risk in perpetrators of violence. Objective The aim of the study was to assess the effect of PTSD symptoms on re-offending risk in prisoner populations with a focus on indirect effects of worry and a negative perception of other people’s support on the relationship between PTSD and re-offending risk. Methods 75 prisoners (25 females, mean age: 44.36 years; 50 males, mean age: 34.7 years) were assessed for exposure to child abuse and neglect, PTSD symptoms, worry, a negative perception of other people’s support and re-offending risk. Mediation analyses tested the indirect effects of worry and a negative perception of other people’s support on the relationship between PTSD and re-offending risk. Results 72% participants presented PTSD symptoms and 30.7% were at risk of re-offending. Mediation analyses supported the hypothesis of a mediation pathway from PTSD to worry and a negative perception of other people’s support to an increased risk of re-offending. Conclusions The results indicate that prisoners report high rates of PTSD symptoms; furthermore, they highlight an important relationship between PTSD and re-offending risk. Findings suggest that future research should test further the indirect effects of negative cognitive and emotional states on the relationship of PTSD and re-offending risk and explore more in depth the role of PTSD to assess and treat prisoners.

To explore the mediating role of measures of persuasion in the relationship between risk perceptions and intentions. The first study included 413 obese subjects (mean age = 45.3 years); the second study, 781 overweight subjects (mean age = 46.6 years). All measures were assessed by self-report. Feelings and intervention judgments were mediators in the relationship between risk perceptions and intention to eat healthier, do more physical activity (study 1) and intention to reduce saturated fat (study 2). Feelings was the only mediator in the relationship between risk perceptions and intention to stop smoking (study 1). Future interventions targeting risk perceptions to increase intentions are likely to be more effective if subjects find the information emotionally impactful, credible, and engaging.

Cognitive mapping tools: review and risk management needs.

Risk managers are increasingly interested in incorporating stakeholder beliefs and other human factors into the planning process. Effective risk assessment and management requires understanding perceptions and beliefs of involved stakeholders, and how these beliefs give rise to actions that influence risk management decisions. Formal analyses of risk manager and stakeholder cognitions represent an important first step. Techniques for diagramming stakeholder mental models provide one tool for risk managers to better understand stakeholder beliefs and perceptions concerning risk, and to leverage this new understanding in developing risk management strategies. This article reviews three methodologies for assessing and diagramming stakeholder mental models--decision-analysis-based mental modeling, concept mapping, and semantic web analysis--and assesses them with regard to their ability to address risk manager needs. © 2012 Society for Risk Analysis.

Relationship between reported prior condom use and current self-perceived risk of acquiring HIV among mobile female sex workers in southern India

PubMed Central

2011-01-01

Background With the evolution of Health Belief Model, risk perception has been identified as one of several core components of public health interventions. While female sex workers (FSWs) in India continue to be at most risk of acquiring and transmitting HIV, little is known about their perception towards risk of acquiring HIV and how this perception depends upon their history of consistent condom use behavior with different type of partners. The objective of this study is to fill this gap in the literature by examining this relationship among mobile FSWs in southern India. Methods We analyzed data for 5,413 mobile FSWs from a cross-sectional behavioral survey conducted in 22 districts from four states in southern India. This survey assessed participants’ demographics, condom use in sex with different types of partners, continuation of sex while experiencing STI symptoms, alcohol use before having sex, and self-perceived risk of acquiring HIV. Descriptive analyses and multilevel logistic regression models were used to examine the associations between risky sexual behaviors and self-perceived risk of acquiring HIV; and to understand the geographical differences in HIV risk perception. Results Of the total mobile FSWs, only two-fifths (40%) perceived themselves to be at high risk of acquiring HIV; more so in the state of Andhra Pradesh (56%) and less in Maharashtra (17%). FSWs seem to assess their current risk of acquiring HIV primarily on the basis of their past condom use behavior with occasional clients and less on the basis of their past condom use behaviors with regular clients and non-paying partners. Prior inconsistent condom use with occasional clients was independently associated with current perception of high HIV risk (adjusted odds ratio [aOR)] = 2.1, 95% confidence interval [CI]: 1.7-2.6). In contrast, prior inconsistent condom use with non-paying partners was associated with current perception of low HIV risk (aOR= 0.7, 95% CI: 0.5-0.9). The congruence between HIV risk perception and condom use with occasional clients was high: only 12% of FSWs reported inconsistent condom use with occasional clients but perceived themselves to be at low risk of acquiring HIV. Conclusion The association between high risk perception of acquiring HIV and inconsistent condom use, especially with regular clients and non-paying partners, has not been completely internalized by this high risk group of mobile FSWs in India. Motivational efforts to prevent HIV should emphasize the importance of accurately assessing an individual’s risk of acquiring HIV based on condom use behavior with all types of partners: occasional and regular clients as well as non-paying partners; and encourage behavior change based on an accurate self-assessment of HIV risk.

The purpose of this study was to assess comparative risk perceptions related to diabetes complications and their associations with patient characteristics in an urban minority sample. The authors developed the Risk Perception Survey-Diabetes Mellitus (RPS-DM) and administered the survey using a Solomon Four group design with a random half of a sample of 599 adults with diabetes. This was the baseline survey to measure comparative risk perceptions in a multiethnic sample prior to implementation of randomly assigned behavioral interventions to improve diabetic retinopathy screening rates. The RPS-DM survey was completed by 250 participants (an 85% completion rate). Participants did not differ significantly by demographics from all other subjects. The sample included 62% women, mean age of 56.5 years, 42.4% Hispanic ethnicity, and 44% black race. The survey showed acceptable psychometric properties in English or Spanish and was feasible to complete by telephone in 12 to 15 minutes. Significant differences by subject characteristics were seen in several survey subscales, including Risk Knowledge by age (P < or = .01) and annual income (P < or = .05), Personal Control by educational level (P < or = .05), and Optimistic Bias by birthplace (P < or = .05) and educational level (P < or = .01). An analysis of variance produced demographic models statistically significant (P < .05) for Risk Knowledge, Personal Control, Environmental Risk, and Optimistic Bias. From 13% to 16% of the variance in the subscale scores was explained by these demographic models. The RPS-DM is the first instrument to measure comparative risk perceptions, including knowledge related to diabetes complications. These data are important for educators and researchers who wish to assess risk perceptions and tailor health/risk communications for their diabetes populations.

2015-01-01

Purpose While rates of adolescent cigarette use have remained constant, rates of marijuana and e-cigarette use are rising. Knowledge and perceptions of risks and benefits of tobacco products impacts adolescents’ decisions to use these products. However, little is known regarding adolescents’ knowledge and perceptions of risks of e-cigarettes and marijuana nor how these perceptions are formed. This study uses qualitative techniques to assess and compare adolescents’ perceptions of the risks and benefits of cigarettes, e-cigarettes, and marijuana. Methods 24 adolescents (9 females and 15 males) from Northern California participated in 6 small-groups discussions. Adolescents were asked what good or bad things might happen from using these products. To assess how perceptions and knowledge of risks and benefits were formed, participants were asked where and from whom they had learned about these products. Results Adolescents described negative consequences of cigarette use, but were much less sure regarding risks of marijuana and e-cigarette use. Conversely, they described few benefits of cigarettes but described a number of benefits of e-cigarette and marijuana use. Adolescents described learning about these products from the media, from family and friends, and from the school environment. Conclusion Adolescents have learned from multiple sources about risks of using cigarettes, but they receive much less and often incorrect information regarding marijuana and e-cigarettes, likely resulting in their positive and often ambivalent perceptions of marijuana and e-cigarettes.

The objective of this study is to evaluate a woman's risk perception for future cardiovascular disease (CVD) after being diagnosed with a hypertensive disorder of pregnancy. A prospective cohort of women diagnosed with a hypertensive disorder of pregnancy (HDP) was studied. Each woman completed two surveys, one prior to hospital discharge and one 2 weeks later, designed to assess knowledge of and risk perception for future CVD based on their recent diagnosis of a HDP. Rates of postpartum depression were also assessed. Of the 146 subjects included, 28% were diagnosed with preeclampsia with severe features, 52.1% with preeclampsia with mild features, and 19.9% had chronic hypertension. Women with severe features and those delivering preterm were more likely to report a perception of increased risk of both recurrent HDP in a future pregnancy (p = 0.004 and 0.005, respectively) and hypertension later in life (p = 0.01 and 0.03, respectively). Women delivering preterm were more likely to report an accurate perception of increased risk of myocardial infarction and stroke compared to those delivering at term (p = 0.006 and 0.002, respectively). Disease severity and preterm delivery were associated with a higher likelihood of the perception of an increased risk for both recurrent HDP and hypertension in the future. Only preterm delivery was associated with a higher risk perception for stroke and myocardial infarction. Interventions targeted at improved health awareness in women diagnosed with HDP are warranted.

Risk perception is an important issue for an efficient management and mitigation measures of natural hazards and theirs negative consequences on social and economic activity. At administrative unit scale (LAU2), local stakeholders play an effective role in case of an emergency situation, regarding the warning and alerting the population, collaboration with specialized institution and managing material assistance during and after the crisis. In addition they are among the best connoisseurs of local community and places, and consequently they could substantial help the national level forces during emergency situations. These issues argues the high degree of responsibilities assigned to Romanian mayors, and is reflected in the legislation in terms of evaluation of damages produced and the management of natural hazards, like landslide and floods. Also their degree of awareness can assess more accurately the collective perception against the individual one. In this work we have assessed the local stakeholders' perception for natural risks in general, and particularly for landslides and floods. We have tested the discrepancies of the specific risks perception and an assessment of correspondence between scientific outputs versus the subjective judgement the administrative decision makers. This approach was based on a questionnaire which was applied in the summer of 2014, to all 98 mayors from Iasi County, north-east Romania. It contained 12 questions structured in a specific mode, from general to particular. The assessment of the answers provided from the commune halls, was realized with integration in a GIS environment of codes assigned to each question, and the overlay with the scientific outputs regarding landslide occurrence and susceptibility and floods risk maps. The differences between the outputs of the questionnaires and the scientific outputs of landslide and flood risk was further analyzed and interpreted. There were registered large variations of answers and important discrepancies between scientific results and the stakeholders' estimations, both for landslides and flood components. Farther multicriterial analysis (clustering method) was applied for highlighting a correspondance between the distance to certain risk areas and stakeholders perception. As a main conclusion we can state that the decision makers perception is strongly influenced by their personal and recent experiences but also by the distance to the source of risk.

This study assessed the effects of multiplex genetic testing on disease risk perceptions among 216 healthy adults. Participants, aged 25-40, were recruited through the Multiplex Initiative, which offered a genetic susceptibility test for eight common diseases. Participants completed baseline telephone and web-based surveys prior to making the testing decision. Three months after the receipt of mailed test results, participants completed a follow-up telephone survey. Risk perceptions for the eight diseases were measured at baseline and follow-up, along with beliefs about genetic causation of those diseases. The main results were: (i) mean risk perceptions were considerably stable from baseline to follow-up; (ii) the best predictors of follow-up risk perceptions were the corresponding baseline perceptions and family history; and (iii) within-individuals, most participants increased or decreased their risk perceptions for specific diseases in concordance with the number of risk markers they carry, their family history and their beliefs about genetic causality of diseases. In conclusion, participants presented a vigilant approach to the interpretation of genetic test results, which provides reassurance with regard to a potential inflation of risk perceptions in the population because of multiplex genetic testing. © 2014 John Wiley & Sons A/S.

The role of conviction in personal disease risk perceptions: What can we learn from research on attitude strength?

PubMed Central

Taber, Jennifer M.; Klein, William M.P.

2016-01-01

Perceived risk for disease is included as a predictor of intentions and behavior in many health behavior theories. However, perceived risk is not always a strong predictor of intentions and behaviors. One reason may be suboptimal conceptualization and measurement of risk perceptions; in particular, research may not capture the conviction and certainty with which a risk perception is held. The rich and independent literature on attitudes might be leveraged to explore whether conviction is an important moderator of the effects of risk perceptions on intentions and behavior. Attitudes are more predictive of intentions when they are high in multiple aspects of attitude strength, including attitude certainty and being more accessible and stable over time. Working from the assumption that risk perceptions have a similar structure and function to attitudes, we consider whether factors known to strengthen the attitude-behavior correspondence might also strengthen the risk perception-behavior correspondence. Although by strict definition risk perceptions are not evaluations (a critical component of attitudes), the predictive validity of risk perceptions may be increased by attention to one’s “conviction” or certainty of perceived risk. We also review recent strategies designed to improve risk perception measurement, including affective and experiential assessments of perceived risk and the importance of allowing people to indicate that they “don’t know” their disease risk. The aim of this paper is to connect two disparate literatures—attitudes and persuasion in social psychology with risk perceptions in health psychology and decision science—in an attempt to stimulate more work on characteristics and proper measurement of risk perceptions.

Risk perception is important for motivating health behavior (e.g., Janz & Becker, 1984), but different measures of the construct may change how important that relationship appears. In two studies, we examined associations between four measures of risk perception, health behavior intentions and possible behavioral determinants. Participants in these studies, who were due for colorectal cancer screening, read an online message about the importance of screening to reduce the chance of cancer. We examined bivariate and multivariate associations between risk perception measures, including absolute, comparative, and feelings-of-risk, and behavioral intentions to screen, general worry, and knowledge and attitudes related to screening. Results across the two studies were consistent, with all risk perception measures being correlated with intentions and attitudes. Multivariate analyses revealed that feelings-of-risk was most predictive of all variables, with the exception of general worry, for which comparative measures were the most predictive. Researchers interested in risk perception should assess feelings-of-risk along with more traditional measures. Those interested in influencing health behavior specifically should attempt to increase feelings of vulnerability rather than numerical risk.

Experts recommend that adults have their global cardiovascular risk assessed. We investigated whether icon arrays increase understanding, recall, perception of CVR, and behavioral intent as compared with numerical information. Male outpatient veterans, at an intermediate to high cardiovascular risk participated in a randomized controlled trial of a computer tutorial presenting individualized risk. Message format was presented in 3 formats: percentages, frequencies, and frequencies with icon arrays. We assessed understanding immediately (T1) and recall at 20 min (T2) and 2 weeks (T3) after the intervention. We assessed perceptions of importance/seriousness, intent to adhere, and self-efficacy at T1. Self-reported adherence was assessed at T3. One-hundred and twenty male veterans participated. Age, education, race, health literacy and numeracy were comparable at baseline. There were no differences in understanding at T1 [p = .31] and recall at T3 [p = .10]. Accuracy was inferior with frequencies with icon arrays than percentages or frequencies at T2 [p ≤ .001]. There were no differences in perception of seriousness and importance for heart disease, behavioral intent, self-efficacy, actual adherence and satisfaction. Icon arrays may impair short-term recall of CVR. Icon arrays will not necessarily result in better understanding and recall of medical risk in all patients. Published by Elsevier Ireland Ltd.

The impact of stigma, experience, and group referent on HIV risk assessments and HIV testing intentions in Namibia.

People often perceive risks for others and themselves differently. This study examines whether personal beliefs about HIV and experience with those living with HIV influence personal risk assessments of contracting HIV in an interview sample of northern Namibians (N=400), but not others' assessments as explained by singular-distribution theory [Klar, Medding, & Sarel (1996). Nonunique invulnerability: Singular versus distributional probabilities and unrealistic optimism in comparative risk judgments. Organizational Behavior and Human Decision Processes, 67, 229-245]. Findings indicate that personal risk perceptions decrease with more HIV stigmatizing beliefs and increase with greater experience, but that those characteristics had no impact on assessments for others' risk. The study also examines whether the size and characteristics of the referent group, peers and the general Namibian population, influence others' risk assessments. Optimistic biases for personal risk versus others' risk appear with the highest discrepancy emerging between personal and general population risk assessments. Further, we found that personal risk perceptions did not mediate the relationship between personal characteristics, beliefs and experiences, and intentions to seek HIV testing.

Flooding risks: a comparison of lay people's perceptions and expert's assessments in Switzerland.

Experts on the risk of flooding have developed very detailed maps for different parts of Switzerland that indicate the types of damage possible and the probabilities of adverse events. Four categories of risk severity are defined on the maps, ranging from high risk to no risk. Based on these existing maps, we selected respondents for a mail survey, some from areas high in risk and others from low-risk regions. Respondents answered several questions related to flood risk perception and preparedness. Survey results showed that respondents' risk perceptions were correlated with the experts' risk assessments. Respondents who lived in areas designated "no risk" by the experts had lower perceptions of risk than respondents who lived in areas with higher levels of designated risk. With regard to concrete prevention behavior, no differences between people living in different risk areas were observed. Survey results further suggest that many inhabitants do not know that flooding maps exist for their region. Results suggest that in some regions people overestimate the risks associated with flooding. Consequently, some people are more afraid of flooding than is justified by the facts. Some people show prevention behavior that most likely is superfluous. However, in other regions people underestimate the risks associated with flooding. These people do not show prevention behavior, and they are not well prepared for an adverse event. Furthermore, results suggest that respondents' experiences with flooding are positively related to their perceptions of flood risk. Findings of the present study are in line with the availability heuristic.

The association between the perception of threat in a dating situation and sexual victimization.

1999-01-01

The purpose of the present investigation was to assess the relation between threat perception in a dating situation and sexual victimization. During an initial session, participants in the experimental condition (n = 116) viewed a video that depicts a heterosexual couple interacting on a date and reflects risk factors for sexual assault. Participants in the control condition (n = 108) viewed a video that does not contain such risk factors. Participants in each condition also responded to survey instruments assessing demographic variables, history of child sexual abuse, history of adolescent sexual assault, and perception of threat cues in the stimulus videos. A subset of participants (n = 66) returned for a 5-month follow-up session and was assessed for experience of sexual assault during the follow-up period. Results fail to support an association between threat perception and sexual victimization history or an association between threat perception and sexual victimization during the follow-up period.

Objective To examine the perception of risk among a group of women with high risk pregnancies who were either planning to give birth in hospital, or at home despite medical advice to the contrary. The intention was to consider differences and similarities between the groups to examine how perception of risk relates to choice of place of birth. Design Qualitative study using semi-structured interviews. Setting Maternity department in a hospital in South East England. Participants Twenty-six women with high risk pregnancies, at least 32 weeks pregnant. Half were planning hospital births and half homebirths. Measurements and findings Semi-structured interviews to investigate women's understanding and assessment of risk. Results were analysed using thematic analysis. Five themes emerged: understanding of situation; judgement of risk; reassuring factors; impact of risk; and coping with risk. Women from both groups had some understanding of the implications of their medical/obstetric conditions. They displayed concerns about their babies' wellbeing. Women planning homebirths assessed their risks as lower and expressed less concerns than women planning hospital births. Women planning hospital births more frequently described following professional advice. Key conclusions Risk perception is individual and subjective. Women with high risk pregnancies who plan to give birth at home perceive risk differently to women who plan hospital births. Implications for practice Healthcare professionals working with women with high risk pregnancies should be aware of the potential for differences in definitions and perceptions of risk within this group.

Transgender women experience a variety of factors that may contribute to HIV risk. The purpose of this study was to explore links among HIV risk perception, knowledge, and sexual risk behaviors of transgender women. A descriptive, correlational study design was used. Fifty transgender women from the South Florida area were enrolled in the study. Transgender women completed a demographic questionnaire and standardized instruments measuring HIV risk perception, knowledge, and sexual risk behaviors. Transgender women reported low levels of HIV risk perception, and had knowledge deficits regarding HIV risk/transmission. Some participants engaged in high-risk sexual behaviors. Predictors of sexual risk behaviors among transgender women were identified. More research is needed with a larger sample size to continue studying factors that contribute to sexual risk behaviors in the understudied population of transgender women. Evidence-based guidelines are available to assist public health nurses in providing care for transgender women. Nurses must assess HIV perception risk and HIV knowledge and provide relevant education to transgender women on ways to minimize sexual risk. © 2016 Wiley Periodicals, Inc.

Data on German farmers risk preference, perception and management strategies.

PubMed

Meraner, Manuela; Finger, Robert

2017-12-01

The extent to which people are willing to take on risk, i.e. their risk preferences as well as subjective risk perception plays a major role in explaining their behavior. This is of particular relevance in agricultural production, which is inherently risky. The data presented here was collected amongst a total of 64 German farmers in 2015. It includes results of three different risk preference elicitation methods (multiple price list, business statements in four relevant domains and general self-assessment) as well as risk perception. Additionally, farm business characteristics (e.g. size, farm-level workforce, succession) and personal farmer characteristics (e.g. age, gender, risk literacy) are included.

Communicating Conservation Status: How Different Statistical Assessment Criteria Affect Perceptions of Extinction Risk.

PubMed

Song, Hwanseok; Schuldt, Jonathon P

2017-09-01

Although alternative forms of statistical and verbal information are routinely used to convey species' extinction risk to policymakers and the public, little is known about their effects on audience information processing and risk perceptions. To address this gap in literature, we report on an experiment that was designed to explore how perceptions of extinction risk differ as a function of five different assessment benchmarks (Criteria A-E) used by scientists to classify species within IUCN Red List risk levels (e.g., Critically Endangered, Vulnerable), as well as the role of key individual differences in these effects (e.g., rational and experiential thinking styles, environmental concern). Despite their normative equivalence within the IUCN classification system, results revealed divergent effects of specific assessment criteria: on average, describing extinction risk in terms of proportional population decline over time (Criterion A) and number of remaining individuals (Criterion D) evoked the highest level of perceived risk, whereas the single-event probability of a species becoming extinct (Criterion E) engendered the least perceived risk. Furthermore, participants scoring high in rationality (analytic thinking) were less prone to exhibit these biases compared to those low in rationality. Our findings suggest that despite their equivalence in the eyes of scientific experts, IUCN criteria are indeed capable of engendering different levels of risk perception among lay audiences, effects that carry direct and important implications for those tasked with communicating about conservation status to diverse publics. © 2016 Society for Risk Analysis.

Conflict or Caveats? Effects of Media Portrayals of Scientific Uncertainty on Audience Perceptions of New Technologies.

PubMed

Binder, Andrew R; Hillback, Elliott D; Brossard, Dominique

2016-04-01

Research indicates that uncertainty in science news stories affects public assessment of risk and uncertainty. However, the form in which uncertainty is presented may also affect people's risk and uncertainty assessments. For example, a news story that features an expert discussing both what is known and what is unknown about a topic may convey a different form of scientific uncertainty than a story that features two experts who hold conflicting opinions about the status of scientific knowledge of the topic, even when both stories contain the same information about knowledge and its boundaries. This study focuses on audience uncertainty and risk perceptions regarding the emerging science of nanotechnology by manipulating whether uncertainty in a news story about potential risks is attributed to expert sources in the form of caveats (individual uncertainty) or conflicting viewpoints (collective uncertainty). Results suggest that the type of uncertainty portrayed does not impact audience feelings of uncertainty or risk perceptions directly. Rather, the presentation of the story influences risk perceptions only among those who are highly deferent to scientific authority. Implications for risk communication theory and practice are discussed. © 2015 Society for Risk Analysis.

Risk perception, risk communication, and stakeholder involvement for biosolids management and research.

PubMed

Beecher, Ned; Harrison, Ellen; Goldstein, Nora; McDaniel, Mary; Field, Patrick; Susskind, Lawrence

2005-01-01

An individual's perception of risk develops from his or her values, beliefs, and experiences. Social scientists have identified factors that affect perceptions of risk, such as whether the risk is knowable (uncertainty), voluntary (can the individual control exposure?), and equitable (how fairly is the risk distributed?). There are measurable differences in how technical experts and citizen stakeholders define and assess risk. Citizen knowledge and technical expertise are both relevant to assessing risk; thus, the 2002 National Research Council panel on biosolids recommended stakeholder involvement in biosolids risk assessments. A survey in 2002 identified some of the factors that influence an individual's perception of the risks involved in a neighbor's use of biosolids. Risk communication was developed to address the gap between experts and the public in knowledge of technical topics. Biosolids management and research may benefit from applications of current risk communication theory that emphasizes (i) two-way communications (dialogue); (ii) that the public has useful knowledge and concerns that need to be acknowledged; and (iii) that what may matter most is the credibility of the purveyor of information and the levels of trustworthiness, fairness, and respect that he or she (or the organization) demonstrates, which can require cultural change. Initial experiences in applying the dialogue and cultural change stages of risk communication theory--as well as consensus-building and joint fact-finding--to biosolids research suggest that future research outcomes can be made more useful to decision-makers and more credible to the broader public. Sharing control of the research process with diverse stakeholders can make research more focused, relevant, and widely understood.

Adolescents' Perceptions of Risks and Benefits of Conventional Cigarettes, E-cigarettes, and Marijuana: A Qualitative Analysis.

Although rates of adolescent cigarette use have remained constant or decreased, rates of marijuana and e-cigarette use are rising. Knowledge and perceptions of risks and benefits of tobacco products impact adolescents' decisions to use these products. However, little is known regarding adolescents' knowledge and perceptions of risks of e-cigarettes and marijuana nor how these perceptions are formed. This study uses qualitative techniques to assess and compare adolescents' perceptions of the risks and benefits of cigarettes, e-cigarettes, and marijuana. Twenty-four adolescents (nine females and 15 males) from Northern California participated in six small-group discussions. Adolescents were asked what good or bad things might happen from using these products. To assess how perceptions and knowledge of risks and benefits were formed, participants were asked where and from whom they had learned about these products. Adolescents described negative consequences of cigarette use but were much less sure regarding risks of marijuana and e-cigarette use. Conversely, they described few benefits of cigarettes but described a number of benefits of e-cigarette and marijuana use. Adolescents described learning about these products from the media, from family and friends, and from the school environment. Adolescents have learned from multiple sources about risks of using cigarettes, but they receive much less and often incorrect information regarding marijuana and e-cigarettes, likely resulting in their positive and often ambivalent perceptions of marijuana and e-cigarettes.

Oncological Genetic Counselling (CGO) allows the identification of a genetic component that increases the risk of developing a cancer. Individuals' psychological reactions are influenced by both the content of the received information and the subjective perception of their own risk of becoming ill or being a carrier of a genetic mutation. This study included 120 participants who underwent genetic counselling for breast and/or ovarian cancer. The aim of the study was to examine the relation between their cancer risk perception and the genetic risk during CGO before receiving genetic test results, considering the influence of some psychological variables, in particular distress, anxiety and depression. Participants completed the following tools during a psychological interview: a socio-demographic form, Cancer Risk Perception (CRP) and Genetic Risk Perception (GRP), Hospital Anxiety and Depression Scale (HADS) and Distress Thermometer (DT). The data seem to confirm our hypothesis. Positive and significant correlations were found between the observed variables. Moreover, genetic risk perception determined an increase in depressive symptomatology and cancer risk perception led to an increase in anxious symptomatology, specifically in participants during cancer treatment. The present results suggest the importance of assessing genetic and cancer risk perception in individuals who undergo CGO, to identify those who are at risk of a decrease in psychological well-being and of developing greater psychological distress.

Precision of information, sensational information, and self-efficacy information as message-level variables affecting risk perceptions.

PubMed

Dahlstrom, Michael F; Dudo, Anthony; Brossard, Dominique

2012-01-01

Studies that investigate how the mass media cover risk issues often assume that certain characteristics of content are related to specific risk perceptions and behavioral intentions. However, these relationships have seldom been empirically assessed. This study tests the influence of three message-level media variables--risk precision information, sensational information, and self-efficacy information--on perceptions of risk, individual worry, and behavioral intentions toward a pervasive health risk. Results suggest that more precise risk information leads to increased risk perceptions and that the effect of sensational information is moderated by risk precision information. Greater self-efficacy information is associated with greater intention to change behavior, but none of the variables influence individual worry. The results provide a quantitative understanding of how specific characteristics of informational media content can influence individuals' responses to health threats of a global and uncertain nature. © 2011 Society for Risk Analysis.

To assess non-medical university students' knowledge and perceived risk of developing oral cavity and oropharyngeal cancer. A cross-sectional survey was conducted among non-medical students of a private Midwestern university in the United States in May 2012. Questionnaire assessed demographic information and contained 21 previously validated questions regarding knowledge and perceived risk of developing oral cavity and oropharyngeal cancer. Knowledge scale was categorized into low and high. Risk level was estimated based on smoking, drinking, and sexual habits. Bivariate associations between continuous and categorical variables were assessed using Pearson correlation and Chi-square tests, respectively. The response rate was 87% (100 out of 115 students approached). Eighty-one percent (81%) had low oral cavity and oropharyngeal cancer knowledge; and only 2% perceived that their oral cavity and oropharyngeal cancer risk was high. Risk perception was negatively correlated with age at sexual debut, r (64) = -0.26, p = 0.037; one-way ANOVA showed a marginally significant association between risk perception and number of sexual partners, F(4, 60) = 2.48, p = 0.05. There was no significant association between knowledge and perception of risk; however, oral cavity and oropharyngeal cancer knowledge was significantly associated with frequency of prevention of STDs (p < 0.05). Although 86% had heard about oral cavity and oropharyngeal cancer, only 18% had heard of oral mouth examination, and 7% of these reported ever having an oral cavity and oropharyngeal cancer exam. Oral cavity and oropharyngeal cancer knowledge and risk perception is low among this student population. Since oral cavity and oropharyngeal cancer incidence is increasingly shifting towards younger adults, interventions must be tailored to this group in order to improve prevention and control.

Assessing the Effects of Information About Global Population Growth on Risk Perceptions and Support for Mitigation and Prevention Strategies.

PubMed

Dawson, Ian G J

2018-05-16

The human population is forecast to increase by 3-4 billion people during this century and many scientists have expressed concerns that this could increase the likelihood of certain adverse events (e.g., climate change and resource shortages). Recent research shows that these concerns are mirrored in public risk perceptions and that these perceptions correlate with a willingness to adopt mitigation behaviors (e.g., reduce resource consumption) and preventative actions (e.g., support actions to limit growth). However, little research has assessed the factors that influence risk perceptions of global population growth (GPG). To contribute to this important goal, this article presents three studies that examined how risk perceptions of GPG might be influenced by textual-visual representations (like those in media and Internet articles) of the potential effects of GPG. Study 1 found that a textual narrative that highlighted the potential negative (cf. positive) consequences of GPG led to higher perceived risk and greater willingness to adopt mitigation behaviors, but not to support preventative actions. Notably, the influence of the narratives on perceived risk was largely moderated by the participant's prior knowledge and perceptions of GPG. Contrary to expectations, studies 2 and 3 revealed, respectively, that photographs depicting GPG-related imagery and graphs depicting GPG rates had no significant effect on the perceived risk of GPG or the willingness to embrace mitigation or preventative actions. However, study 3 found that individuals with higher "graph literacy" perceived GPG as a higher risk and were more willing to adopt mitigation behaviors and support preventative actions. © 2018 Society for Risk Analysis.

Background Opioid-related mortality continues to increase in the United States. The current study assesses demographic and behavioral predictors of perceived overdose risk among individuals who use opioids illicitly. By examining these correlates in the context of established overdose risk factors, we aim to assess whether characteristics and behaviors that have been associated with actual overdose risk translate to higher perception of risk. Methods We conducted a cross-sectional survey of 172 adult illicit opioid users in San Francisco, CA and used multivariable logistic regression to identify predictors of perception of high risk for opioid overdose. Results Age (aOR=0.96, 95%CI=0.93-1.00) and number of injection days per month (0.91, 0.86-0.97) were associated with a lower odds of perceived high overdose risk. There was no independent association between use of opioid analgesics, concurrent use of opioids and benzodiazepines or cocaine, or HIV status and overdose risk perception. Conclusions Opioid users who injected more frequently and those who were older were less likely to perceive themselves as being at risk of overdose, notwithstanding that those who inject more are at higher risk of overdose and those who are older are at higher risk overdose mortality. In addition, despite being established overdose risk factors, there was no relationship between use of opioid analgesics, concurrent use of opioids and cocaine or benzodiazepines, or self-reported HIV status and overdose risk perception. These findings highlight key populations of opioid users and established risk factors that may merit focused attention as part of education-based overdose prevention and opioid management strategies.

Abstract Background: Improving employees’ perception of organizational climate, and coaching them to remain steadfast when managing occupational risks associated with their job, might have an important effect on their psychosocial wellbeing and occupational health. This study examined the effects of a rational emotive occupational health therapy intervention program on the perceptions of organizational climate and occupational risk management practices. Methods: The participants were 77 electronics technology employees in the south-east of Nigeria. The study used a pretest–posttest control group design. Results: The rational emotive occupational health therapy intervention program significantly improved perceptions of the organizational climate for the people in the treatment group compared to those in the waitlist control group at post-intervention and follow-up assessments. Occupational risk management practices of the employees in the treatment group were also significantly better than those in the waitlist control group at the same 2 assessments. Conclusions: Corporate application of a rational emotive behavior therapy as an occupational health therapy intervention program is essential for improving the perceptions of organizational climate and promoting the adoption of feasible occupational risk management strategies in the workplace.

Previous studies were conflicting regarding the associations between HPV vaccination, cervical cancer risk perceptions, high-risk sexual behaviors and STIs. This study compared the HPV-vaccinated and non-vaccinated young women in Uganda regarding cervical cancer risk perceptions, high-risk sexual behaviors, syphilis and HIV infections 5 years after vaccine implementation. This was a population-based comparative cross-sectional survey conducted in Uganda. The 438 participants were sexually active young women aged 15-24 years and mean age was 18.6 (SD 1.4). The majority (53.0%) were HPV-vaccinated in 2008 without assessment of sexual activity prior to HPV vaccination. Upon verbal assessment of sexual activity at the time of follow-up, data were collected using a questionnaire and laboratory testing of blood samples for syphilis and HIV infections. There were no significant differences between the HPV-vaccinated and non-vaccinated groups regarding the prevalence of high-risk sexual behaviors, syphilis and HIV infections. Cervical cancer risk perceptions and age at sexual debut were nonetheless significantly lower among the vaccinated group compared to their non-vaccinated counterparts. However, HPV vaccination was not significantly associated to cervical cancer risk perceptions and early age at sexual debut in multivariate logistic regression analysis. We found no associations between HPV vaccination, cervical cancer risk perceptions, high-risk sexual behaviors, syphilis and HIV infections among young women in Uganda 5 years after vaccine implementation. Young girls in the study population were found to be sexually active at a young age, affirming the importance of targeting girls of younger age for HPV vaccination.

Fuel poverty increases risk of mould contamination, regardless of adult risk perception & ventilation in social housing properties.

Fuel poverty affects 2.4 million UK homes leading to poor hygrothermal conditions and risk of mould and house dust mite contaminations, which in turn increases risk of asthma exacerbation. For the first time we assess how fuel poverty, occupants' risk perception and use of mechanical ventilation mediate the risk of mould contamination in social housing. Postal questionnaires were sent to 3867 social housing properties to collect adult risk perception, and demographic and environmental information on occupants. Participant details were linked to data pertaining to the individual properties. Multiple logistic regression was used to calculate odds ratios and confidence intervals while allowing for clustering of individuals coming from the same housing estate. We used Structured Equation Modelling and Goodness of Fit analysis in mediation analyses to examine the role of fuel poverty, risk perception, use of ventilation and energy efficiency. Eighteen percent of our target social housing populations (671 households) were included into our study. High risk perception (score of 8-10) was associated with reduced risk of mould contamination in the bedrooms of children (OR 0.5 95% CI; 0.3-0.9) and adults (OR 0.4 95% CI; 0.3-0.7). High risk perception of living with inadequate heating and ventilation reduced the risk of mould contamination (OR 0.5 95% CI; 0.3-0.8 and OR 0.5 95% CI; 0.3-0.7, respectively). Participants living with inadequate heating and not heating due to the cost of fuel had an increased risk of mould contamination (OR 3.4 95% CI; 2.0-5.8 and OR 2.2 95% CI; 1.5-3.2, respectively). Increased risk perception and use of extractor fans did not mediate the association between fuel poverty behaviours and increased risk of mould contamination. Fuel poverty behaviours increased the risk of mould contamination, which corresponds with existing literature. For the first time we used mediation analysis to assess how this association maybe modified by occupant behaviours. Increased risk perception and use of extractor fans did not modify the association between fuel poverty and mould contamination. This suggests that fuel poor populations may not benefit from energy efficiency interventions due to ineffective heating and ventilation practices of those occupants residing participating households. Our findings may be modified by a complex interaction between occupant behaviours and the built environment. We found that participant age, occupancy, SES, pets, drying washing indoors, geographic location, architectural design/age of the property, levels of insulation and type of heating regulated risk of mould contamination. Fuel poverty behaviours affected around a third of participating households and represent a risk factor for increased exposures to damp and mouldy conditions, regardless of adult risk perception, heating and ventilation practices. This requires multidisciplinary approach to assess the complex interaction between occupant behaviours, risk perception, the built environment and the effective use of heating and ventilation practices. Our findings have implications for housing policies and future housing interventions. Effective communication strategies focusing on awareness and perception of risk may help address indoor air quality issues. This must be supported by improved household energy efficiency with the provision of more effective heating and ventilation strategies, specifically to help alleviate those suffering from fuel poverty.

This study focuses on levels of concern for hurricanes among individuals living along the Gulf Coast during the quiescent two-year period following the exceptionally destructive 2005 hurricane season. A small study of risk perception and optimistic bias was conducted immediately following Hurricanes Katrina and Rita. Two years later, a follow-up was done in which respondents were recontacted. This provided an opportunity to examine changes, and potential causal ordering, in risk perception and optimistic bias. The analysis uses 201 panel respondents who were matched across the two mail surveys. Measures included hurricane risk perception, optimistic bias for hurricane evacuation, past hurricane experience, and a small set of demographic variables (age, sex, income, and education). Paired t-tests were used to compare scores across time. Hurricane risk perception declined and optimistic bias increased. Cross-lagged correlations were used to test the potential causal ordering between risk perception and optimistic bias, with a weak effect suggesting the former affects the latter. Additional cross-lagged analysis using structural equation modeling was used to look more closely at the components of optimistic bias (risk to self vs. risk to others). A significant and stronger potentially causal effect from risk perception to optimistic bias was found. Analysis of the experience and demographic variables' effects on risk perception and optimistic bias, and their change, provided mixed results. The lessening of risk perception and increase in optimistic bias over the period of quiescence suggest that risk communicators and emergency managers should direct attention toward reversing these trends to increase disaster preparedness. © 2013 Society for Risk Analysis.

Comparison of Different Risk Perception Measures in Predicting Seasonal Influenza Vaccination among Healthy Chinese Adults in Hong Kong: A Prospective Longitudinal Study

2013-01-01

Background Risk perception is a reported predictor of vaccination uptake, but which measures of risk perception best predict influenza vaccination uptake remain unclear. Methodology During the main influenza seasons (between January and March) of 2009 (Wave 1) and 2010 (Wave 2),505 Chinese students and employees from a Hong Kong university completed an online survey. Multivariate logistic regression models were conducted to assess how well different risk perceptions measures in Wave 1 predicted vaccination uptake against seasonal influenza in Wave 2. Principal Findings The results of the multivariate logistic regression models showed that feeling at risk (β = 0.25, p = 0.021) was the better predictor compared with probability judgment while probability judgment (β = 0.25, p = 0.029 ) was better than beliefs about risk in predicting subsequent influenza vaccination uptake. Beliefs about risk and feeling at risk seemed to predict the same aspect of subsequent vaccination uptake because their associations with vaccination uptake became insignificant when paired into the logistic regression model. Similarly, to compare the four scales for assessing probability judgment in predicting vaccination uptake, the 7-point verbal scale remained a significant and stronger predictor for vaccination uptake when paired with other three scales; the 6-point verbal scale was a significant and stronger predictor when paired with the percentage scale or the 2-point verbal scale; and the percentage scale was a significant and stronger predictor only when paired with the 2-point verbal scale. Conclusions/Significance Beliefs about risk and feeling at risk are not well differentiated by Hong Kong Chinese people. Feeling at risk, an affective-cognitive dimension of risk perception predicts subsequent vaccination uptake better than do probability judgments. Among the four scales for assessing risk probability judgment, the 7-point verbal scale offered the best predictive power for subsequent vaccination uptake. PMID:23894292

Current HIV-risk perception refers to the extent to which individuals think they might be HIV-positive. This belief, distinct from the perceived risk about being infected with HIV in the future, is likely to have a range of important consequences. These consequences may include both psychological effects (e.g., impacts on well-being) and behavioural effects (e.g., HIV testing uptake). Given these possible outcomes, and the suggested importance of risk perception in health behaviour models, understanding the behavioural and psychological antecedents of current HIV-risk perception is crucial. This systematic review investigates the relationship between behavioural and psychological factors and current HIV-risk perception (in individuals who are unaware of their actual HIV status). Eight studies were eligible for inclusion in the review (five quantitative and three qualitative studies). Drug risk behaviour and sexual risk behaviour (both self and partner) were often associated with current HIV-risk perception, although other studies failed to show a relationship between one's own sexual risk behaviour and risk perception. Psychological factors were only rarely assessed in relation to current HIV-risk perception. Where these variables were included, there was evidence that experiencing symptoms perceived to be consistent with HIV and prompts to test were associated with increased current HIV-risk perception. These findings are consistent with the Common-Sense Model (CSM) of illness representation and self-regulation. Methodological quality criteria were rarely met for the included studies. In addition, it was often difficult to ascertain whether potentially includable studies were eligible due to imprecise definitions of HIV-risk perception. Research and practice implications are discussed, with particular emphasis on the role of risk appraisals as a potential mediator of the relationship between HIV-risk behaviour, symptoms and current HIV-risk perception.

To assess how nurses' perception of their safety and risk of violence was affected by their work environment and whether this perception correlated with their actual risk. The work environment has an impact on nurses' perception of their risk of violence and this perception affects worker productivity, quality, employee retention, worker satisfaction and their actual safety. A cross-sectional survey was conducted in person of 314 emergency department nurses and 143 psychiatric nurses, and assault data was collected from injury logs. This study found that nurses in the emergency and psychiatric units differed in their perception of violence and safety. The workplace elements that led to a perception of lower risk of violence were not correlated with a lower rate of injury from violent acts. The nurses' beliefs about the adequacy of security equipment, security guards and the frequency of verbal abuse were strongly correlated with perceived safety. Several factors that influence nurses' perception of their risk of violence are not well correlated with their actual risk. Managers must address workplace elements that affect nurse perceptions because this has an impact on quality and employee retention. They must also address factors that have an impact on the actual risk of violence because this study showed, for the first time, that these may differ from perceptions. © 2012 Blackwell Publishing Ltd.

This study evaluates the Alzheimer disease risk perceptions of individuals who accurately recall their genetics-based Alzheimer disease risk assessment. Two hundred forty-six unaffected first-degree relatives of patients with Alzheimer disease were enrolled in a multisite randomized controlled trial examining the effects of communicating APOE genotype and lifetime Alzheimer disease risk information. Among the 158 participants who accurately recalled their Alzheimer disease risk assessment 6 weeks after risk disclosure, 75 (47.5%) believed their Alzheimer disease risk was more than 5% points different from the Alzheimer disease risk estimate they were given. Within this subgroup, 69.3% believed that their Alzheimer disease risk was higher than what they were told (discordant high), whereas 30.7% believed that their Alzheimer disease risk was lower (discordant low). Participants with a higher baseline risk perception were more likely to have a discordant-high risk perception (P < 0.05). Participants in the discordant-low group were more likely to be APOE epsilon4 positive (P < 0.05) and to score higher on an Alzheimer disease controllability scale (P < 0.05). Our results indicate that even among individuals who accurately recall their Alzheimer disease risk assessment, many people do not take communicated risk estimates at face value. Further exploration of this clinically relevant response to risk information is warranted.

Uncertainty is inherent to flood risk assessments because of the complexity of the human-water system, which is characterised by nonlinearities and interdependencies, because of limited knowledge about system properties and because of cognitive biases in human perception and decision-making. On top of the uncertainty associated with the assessment of the existing risk to extreme events, additional uncertainty arises because of temporal changes in the system due to climate change, modifications of the environment, population growth and the associated increase in assets. Novel risk assessment concepts are needed that take into account all these sources of uncertainty. They should be based on the understanding of how flood extremes are generated and how they change over time. They should also account for the dynamics of risk perception of decision makers and population in the floodplains. In this talk we discuss these novel risk assessment concepts through examples from Flood Frequency Hydrology, Socio-Hydrology and Predictions Under Change. We believe that uncertainty quantification in flood risk assessment should lead to a robust approach of integrated flood risk management aiming at enhancing resilience rather than searching for optimal defense strategies.

Low perception of HIV risk despite behaviors associated with increased risk is thought to be a contributing factor for a higher prevalence of HIV in blacks than other groups in the United States. We sought to determine HIV risk perception and its impact on safer sex practices and interest in preexposure prophylaxis (PrEP). From August 1 to October 31, 2010, an anonymous survey was conducted at a sexually transmitted infection clinic asking questions about demographics, risk behaviors, and PrEP interest. Participants were categorized into high-risk, moderate-risk, and low-risk groups according to predefined HIV risk characteristics. Only heterosexual high-risk participants were further assessed for their risk perception, condom use and PrEP interest. There were 494 participants; 63% male, 70% blacks, 88% heterosexual; 83% were categorized into the high-risk group. Of the 359 heterosexual high-risk participants, 301 (84%) perceived themselves at no or low-risk. Rates of consistent condom use with vaginal, oral, and anal sex were low (<20%) in this group despite high levels of knowledge about HIV transmission risks. Rates of condom use were not affected by risk perception. No interest in PrEP was associated with low education level (adjusted odds ratio 4.97; p=0.02) and low risk perception. These findings suggest that despite having knowledge about HIV transmission risks, the majority of high-risk participants did not recognize their risks and used condoms with low frequency. Low risk perception and low education level may impact PrEP interest. Enhanced interventions are needed to improve HIV risk perception, safer sex practices, and knowledge about PrEP.

Dispositional optimism and risk perceptions are each associated with health-related behaviors and decisions and other outcomes, but little research has examined how these constructs interact, particularly in consequential health contexts. The predictive validity of risk perceptions for health-related information seeking and intentions may be improved by examining dispositional optimism as a moderator, and by testing alternate types of risk perceptions, such as comparative and experiential risk. Participants (n = 496) had their genomes sequenced as part of a National Institutes of Health pilot cohort study (ClinSeq®). Participants completed a cross-sectional baseline survey of various types of risk perceptions and intentions to learn genome sequencing results for differing disease risks (e.g., medically actionable, nonmedically actionable, carrier status) and to use this information to change their lifestyle/health behaviors. Risk perceptions (absolute, comparative, and experiential) were largely unassociated with intentions to learn sequencing results. Dispositional optimism and comparative risk perceptions interacted, however, such that individuals higher in optimism reported greater intentions to learn all 3 types of sequencing results when comparative risk was perceived to be higher than when it was perceived to be lower. This interaction was inconsistent for experiential risk and absent for absolute risk. Independent of perceived risk, participants high in dispositional optimism reported greater interest in learning risks for nonmedically actionable disease and carrier status, and greater intentions to use genome information to change their lifestyle/health behaviors. The relationship between risk perceptions and intentions may depend on how risk perceptions are assessed and on degree of optimism. (c) 2015 APA, all rights reserved.

"The Dose Makes the Poison": Informing Consumers About the Scientific Risk Assessment of Food Additives.

2016-01-01

Intensive risk assessment is required before the approval of food additives. During this process, based on the toxicological principle of "the dose makes the poison,ˮ maximum usage doses are assessed. However, most consumers are not aware of these efforts to ensure the safety of food additives and are therefore sceptical, even though food additives bring certain benefits to consumers. This study investigated the effect of a short video, which explains the scientific risk assessment and regulation of food additives, on consumers' perceptions and acceptance of food additives. The primary goal of this study was to inform consumers and enable them to construct their own risk-benefit assessment and make informed decisions about food additives. The secondary goal was to investigate whether people have different perceptions of food additives of artificial (i.e., aspartame) or natural origin (i.e., steviolglycoside). To attain these research goals, an online experiment was conducted on 185 Swiss consumers. Participants were randomly assigned to either the experimental group, which was shown a video about the scientific risk assessment of food additives, or the control group, which was shown a video about a topic irrelevant to the study. After watching the video, the respondents knew significantly more, expressed more positive thoughts and feelings, had less risk perception, and more acceptance than prior to watching the video. Thus, it appears that informing consumers about complex food safety topics, such as the scientific risk assessment of food additives, is possible, and using a carefully developed information video is a successful strategy for informing consumers. © 2015 Society for Risk Analysis.

Design of risk communication strategies based on risk perception among farmers exposed to pesticides in Rio de Janeiro State, Brazil.

This study aims to assess pesticide exposure risk perception among farmers from three rural areas of Nova Friburgo, Rio de Janeiro State, Brazil. Data were collected through semi-structured interviews with 66 adults and participatory workshops with 27 teenagers and analyzed through content analysis techniques. Systematized results were discussed at local meetings, and two risk communication initiatives were devised. Study results demonstrated the use of defensive strategies by men and a diminished risk perception among women. Teenagers relied on parents to develop their own work practices. These findings supported the importance of cultural and social determinants of farmers' understandings of risk and of the relevance of different pesticide exposure pathways. Risk perceptions and work practices are strongly influenced by local cultural patterns and, therefore, must be taken into account when developing effective intervention strategies, including risk communication initiatives.

During global health crises, such as the recent H1N1 pandemic, the mass media provide the public with timely information regarding risk. To obtain new insights into how these messages are received, we measured neural data while participants, who differed in their preexisting H1N1 risk perceptions, viewed a TV report about H1N1. Intersubject correlation (ISC) of neural time courses was used to assess how similarly the brains of viewers responded to the TV report. We found enhanced intersubject correlations among viewers with high-risk perception in the anterior cingulate, a region which classical fMRI studies associated with the appraisal of threatening information. By contrast, neural coupling in sensory-perceptual regions was similar for the high and low H1N1-risk perception groups. These results demonstrate a novel methodology for understanding how real-life health messages are processed in the human brain, with particular emphasis on the role of emotion and differences in risk perceptions.

Are College Students' Assessments of Threat Shaped by the Dangers of Their Childhood Environment?

Humans internalize environmental cues of mortality risk at an early age, which influences subsequent risk perceptions and behavior. In this respect, an individual's current risk assessment may be viewed as an adaptive response to the dangers present within his or her early local environment. Here we examine the relationship between several variables indicating threat within an individual's early environment (e.g., prevalence of violent and property crimes, registered sex offenders) and their perception of crime risk within both the childhood and current adult environments. We recruited a group of 657 students who hail from diverse geographic backgrounds to provide the zip code location of their childhood residence along with subjective ratings of danger of that and their current location, which enabled us to compare their ratings of risk/danger with the federally reported crime statistics of each setting. Our results indicate that the early prevalence of registered sex offenders indeed influences an individual's risk perception in adulthood, and that these factors have a differential effect on males and females. Our findings provide support for the theory that early environmental factors signaling danger affect how individuals assess risk within their adult environment. © The Author(s) 2015.

Environmental insecurity is a source and outcome of biodiversity declines and social conflict. One challenge to scaling insecurity reduction policies is that empirical evidence about local attitudes is overwhelmingly missing. We set three objectives: determine how local people rank risk associated with different sources of environmental insecurity; assess perceptions of environmental insecurity, biodiversity exploitation, myths of nature and risk management preferences; and explore relationships between perceptions and biodiversity exploitation. We conducted interviews (N = 88) with residents of Madagascar’s Torotorofotsy Protected Area, 2014. Risk perceptions had a moderate effect on perceptions of environmental insecurity. We found no effects of environmental insecurity on biodiversity exploitation. Results offer one if not the first exploration of local perceptions of illegal biodiversity exploitation and environmental security. Local people’s perception of risk seriousness associated with illegal biodiversity exploitation such as lemur hunting (low overall) may not reflect perceptions of policy-makers (considered to be high). Discord is a key entry point for attention. PMID:27082106

Towards a better reliability of risk assessment: development of a qualitative & quantitative risk evaluation model (Q2REM) for different trades of construction works in Hong Kong.

Fung, Ivan W H; Lo, Tommy Y; Tung, Karen C F

2012-09-01

Since the safety professionals are the key decision makers dealing with project safety and risk assessment in the construction industry, their perceptions of safety risk would directly affect the reliability of risk assessment. The safety professionals generally tend to heavily rely on their own past experiences to make subjective decisions on risk assessment without systematic decision making. Indeed, understanding of the underlying principles of risk assessment is significant. In this study, the qualitative analysis on the safety professionals' beliefs of risk assessment and their perceptions towards risk assessment, including their recognitions of possible accident causes, the degree of differentiations on their perceptions of risk levels of different trades of works, recognitions of the occurrence of different types of accidents, and their inter-relationships with safety performance in terms of accident rates will be explored in the Stage 1. At the second stage, the deficiencies of the current general practice for risk assessment can be sorted out firstly. Based on the findings from Stage 1 and the historical accident data from 15 large-scaled construction projects in 3-year average, a risk evaluation model prioritizing the risk levels of different trades of works and which cause different types of site accident due to various accident causes will be developed quantitatively. With the suggested systematic accident recording techniques, this model can be implemented in the construction industry at both project level and organizational level. The model (Q(2)REM) not only act as a useful supplementary guideline of risk assessment for the construction safety professionals, but also assists them to pinpoint the potential risks on site for the construction workers under respective trades of works through safety trainings and education. It, in turn, arouses their awareness on safety risk. As the Q(2)REM can clearly show the potential accident causes leading to different types of accident by trade of works, it helps the concerned safety professionals and parties to plan effective accident prevention measures with reference to the priority of the risk levels.

Wind speed perception and risk.

PubMed

Agdas, Duzgun; Webster, Gregory D; Masters, Forrest J

2012-01-01

How accurately do people perceive extreme wind speeds and how does that perception affect the perceived risk? Prior research on human-wind interaction has focused on comfort levels in urban settings or knock-down thresholds. No systematic experimental research has attempted to assess people's ability to estimate extreme wind speeds and perceptions of their associated risks. We exposed 76 people to 10, 20, 30, 40, 50, and 60 mph (4.5, 8.9, 13.4, 17.9, 22.3, and 26.8 m/s) winds in randomized orders and asked them to estimate wind speed and the corresponding risk they felt. Multilevel modeling showed that people were accurate at lower wind speeds but overestimated wind speeds at higher levels. Wind speed perceptions mediated the direct relationship between actual wind speeds and perceptions of risk (i.e., the greater the perceived wind speed, the greater the perceived risk). The number of tropical cyclones people had experienced moderated the strength of the actual-perceived wind speed relationship; consequently, mediation was stronger for people who had experienced fewer storms. These findings provide a clearer understanding of wind and risk perception, which can aid development of public policy solutions toward communicating the severity and risks associated with natural disasters.

The communication of natural hazards and their consequences is one of the more relevant ethical issues faced by scientists. In the last years, social studies have provided evidence that risk communication is strongly influenced by the risk perception of people. In order to develop effective information and risk communication strategies, the perception of risks and the influencing factors should be known. A theory that offers an integrative approach to understanding and explaining risk perception is still missing. To explain risk perception, it is necessary to consider several perspectives: social, psychological and cultural perspectives and their interactions. This paper presents the results of the CATI survey on seismic risk perception in Italy, conducted by INGV researchers on funding by the DPC. We built a questionnaire to assess seismic risk perception, with a particular attention to compare hazard, vulnerability and exposure perception with the real data of the same factors. The Seismic Risk Perception Questionnaire (SRP-Q) is designed by semantic differential method, using opposite terms on a Likert scale to seven points. The questionnaire allows to obtain the scores of five risk indicators: Hazard, Exposure, Vulnerability, People and Community, Earthquake Phenomenon. The questionnaire was administered by telephone interview (C.A.T.I.) on a statistical sample at national level of over 4,000 people, in the period January -February 2015. Results show that risk perception seems be underestimated for all indicators considered. In particular scores of seismic Vulnerability factor are extremely low compared with house information data of the respondents. Other data collected by the questionnaire regard Earthquake information level, Sources of information, Earthquake occurrence with respect to other natural hazards, participation at risk reduction activities and level of involvement. Research on risk perception aims to aid risk analysis and policy-making by providing a basis for understanding and anticipating public responses to hazards and improving the communication of risk information among people, technical experts, and decision-makers. Those dealing with seismic risk need to understand what people think about and how they respond to this risk. Without such understanding, well-intended policies may be ineffective. (Slovic, 1987). For these reasons we believe that comparing the perception factors with the "real factors" of seismic risk, is a crucial point to understand the relationship between scientific knowledge and public understanding. Without a comparison with reality, research on risk perception is just an intellectual exercise.

Most Americans recognize that smoking causes serious diseases, yet many Americans continue to smoke. One possible explanation for this paradox is that perhaps Americans do not accurately perceive the extent to which smoking increases the probability of adverse health outcomes. This paper examines the accuracy of Americans’ perceptions of the absolute risk, attributable risk, and relative risk of lung cancer, and assesses which of these beliefs drive Americans’ smoking behavior. Using data from three national surveys, statistical analyses were performed by comparing means, medians, and distributions, and by employing Generalized Additive Models. Perceptions of relative risk were associated as expected with smoking onset and smoking cessation, whereas perceptions of absolute risk and attributable risk were not. Additionally, the relation of relative risk with smoking status was stronger among people who held their risk perceptions with more certainty. Most current smokers, former smokers, and never-smokers considerably underestimated the relative risk of smoking. If, as this paper suggests, people naturally think about the health consequences of smoking in terms of relative risk, smoking rates might be reduced if public understanding of the relative risks of smoking were more accurate and people held those beliefs with more confidence.

Risk perception and motivation to quit smoking: a partial test of the Health Action Process Approach.

PubMed

Williams, Rebecca J; Herzog, Thaddeus A; Simmons, Vani N

The Health Action Process Approach (HAPA) posits a distinction between pre-intentional motivation processes and a post-intentional volition process that leads to the actual behavior change. For smoking cessation, the HAPA predicts that increased risk perceptions would foster a decision to quit smoking. From a cross-sectional perspective, the HAPA predicts that those who do not intend to quit (non-intenders) should have lower risk perceptions than those who do intend to quit (intenders). Adult smokers participated in a cross-sectional survey. Multiple measures of motivation to quit smoking and risk perceptions for smoking were assessed. ANOVA and contrast analysis were employed for data analysis. The results were generally supportive of the HAPA. Non-intenders had systematically lower risk perceptions compared to intenders. Most of these findings were statistically significant. The results demonstrated that risk perceptions distinguish non-intenders from intenders. These results suggest that smokers low in motivation to quit could benefit from information and reminders about the serious health problems caused by smoking. Copyright © 2011 Elsevier Ltd.

While male circumcision reduces the risk of female-to-male HIV transmission and certain sexually transmitted infections (STIs), there is little evidence that circumcision provides women with direct protection against HIV. This study used qualitative methods to assess women’s perceptions of male circumcision in Iringa, Tanzania. Women in this study had strong preferences for circumcised men because of the low risk perception of HIV with circumcised men, social norms favoring circumcised men, and perceived increased sexual desirability of circumcised men. The health benefits of male circumcision were generally overstated; many respondents falsely believed that women are also directly protected against HIV and that the risk of all STIs is greatly reduced or eliminated in circumcised men. Efforts to engage women about the risks and limitations of male circumcision, in addition to the benefits, should be expanded so that women can accurately assess their risk of HIV or STIs during sexual intercourse with circumcised men.

To test the hypothesis that responses to coronary heart disease (CHD) risk estimates are heightened by use of ratio formats, peer group risk information, and long time frames. Cross-sectional, experimental, between-factors design. Three regions in England. A total of 740 men and women ages 30 to 70 years. Risk perception, "emotional" response, intention to change lifestyle. Logistic regression was used to investigate the impact of numerical format (ratio vs. percentage), peer group risk (personal vs. peer group), and time frame (10-year vs. 30-year) on risk perception. Analysis of variance was used to investigate the impact of these factors on emotional response and intention to change lifestyle questions. Higher perceived risk was observed when risk was presented as a ratio (p < .001) and when it was supplemented with peer group risk estimates (p = .006). Emotional responses to risk information were heightened when risk was presented as a ratio (p = .0004) and supplemented with peer group risk estimates (p = .002). Presentation with ratios also increased intention to make lifestyle changes (p = .047). Perception of CHD risk information is affected by the presentation format. Where absolute risks may appear low, use of ratios and supplementation of personal risk estimates with peer group risk may increase risk perception.

Exploring beliefs about personal risk for human immunodeficiency virus (HIV) infection is essential to understanding what motivates people to engage in behaviors that reduce or increase their risk of HIV infection. Therefore, the current study's objective was to examine the effects of a Rational-Emotive Health Education Program (REHEP) on HIV risk perceptions among in-school adolescents in Anambra State, Nigeria.Forty-four participants were identified as having high-risk perceptions about HIV infection through a self-report questionnaire and met the inclusion criteria. The treatment process was guided by a REHEP manual and consisted of 8 weeks of full intervention and 2 weeks of follow-up meetings that marked the end of intervention. The study used repeated measures analysis of variance to assess improvements in individual participants and across control and treatment group risk perceptions after the intervention.HIV risk perceptions of in-school adolescents did not differ across the treatment and control groups at baseline. Through REHEP, HIV risk perceptions significantly reduced in the treatment group compared to those in the control group. REHEP had significant effect on HIV risk perceptions of in-school adolescents exposed to treatment group, despite their sex. Religious background did not determine the significant effect of REHEP on HIV risk perceptions of in-school adolescents in the treatment group.Follow-up studies that would use a REHEP to assist client population from other parts of the country to promote HIV risk reduction, especially among those with high-risk behavior, are needed in Nigeria.

The association between HIV/AIDS-related knowledge and perception of risk for infection: a systematic review.

This systematic review tries to elucidate the association between what people know about HIV/AIDS and how they perceive their risk of infection. The initial search for articles yielded 1,595 abstracts, 16 of which met the inclusion criteria. Five studies found a positive correlation, four reported a negative correlation and seven found no association between knowledge and risk perception. It was found that the existing psychometrically sound measure of HIV/AIDS risk perception had not been used in any of the studies. The context in which the risk is assessed is pivotal to whether an association between knowledge and the perceived risk is found. Biases in judgement such as optimistic bias, psychological distancing, anchoring bias and overconfidence also explain how knowledge may fail to predict risk perception. It was concluded that the association between HIV/AIDS knowledge and risk perception might follow a continuum from positive to no association and finally to negative. The hypothesis, however, still needs to be studied further. © Royal Society for Public Health 2015.

Affect-laden imagery and risk taking: the mediating role of stress and risk perception.

PubMed

Traczyk, Jakub; Sobkow, Agata; Zaleskiewicz, Tomasz

2015-01-01

This paper investigates how affect-laden imagery that evokes emotional stress influences risk perception and risk taking in real-life scenarios. In a series of three studies, we instructed participants to imagine the consequences of risky scenarios and then rate the intensity of the experienced stress, perceived risk and their willingness to engage in risky behavior. Study 1 showed that people spontaneously imagine negative rather than positive risk consequences, which are directly related to their lower willingness to take risk. Moreover, this relationship was mediated by feelings of stress and risk perception. Study 2 replicated and extended these findings by showing that imagining negative risk consequences evokes psychophysiological stress responses observed in elevated blood pressure. Finally, in Study 3, we once again demonstrated that a higher intensity of mental images of negative risk consequences, as measured by enhanced brain activity in the parieto-occipital lobes, leads to a lower propensity to take risk. Furthermore, individual differences in creating vivid and intense negative images of risk consequences moderated the strength of the relationship between risk perception and risk taking. Participants who created more vivid and intense images of negative risk consequences paid less attention to the assessments of riskiness in rating their likelihood to take risk. To summarize, we showed that feelings of emotional stress and perceived riskiness mediate the relationship between mental imagery and risk taking, whereas individual differences in abilities to create vivid mental images may influence the degree to which more cognitive risk assessments are used in the risk-taking process.

Understanding emerging trends in public perceptions of nanomaterials is critically important for those who regulate risks. A number of surveys have explored public perceptions of their risks and benefits. In this paper we meta-analyse these surveys to assess the extent to which the following four hypotheses derived from previous studies of new technologies might be said to be valid for nanotechnologies: risk aversion will prevail over benefit appreciation; an increase in knowledge will not result in reduced aversion to risks; judgements will be malleable and subject to persuasion given risk-centric information; and contextual, psychometric and attitudinal predictors of perceived risk from prior studies can help anticipate future perceptions of nanotechnologies. We find that half the public has at least some familiarity with nanotechnology, and those who perceive greater benefits outnumber those who perceive greater risks by 3 to 1. However, a large minority of those surveyed (44%) is unsure, suggesting that risk judgements are highly malleable. Nanotechnology risk perceptions also appear to contradict some long-standing findings. In particular, unfamiliarity with nanotechnology is, contrary to expectations, not strongly associated with risk aversion and reduced `knowledge deficits' are correlated with positive perceptions in this early and controversy-free period. Psychometric variables, trust and affect continue to drive risk perceptions in this new context, although the influence of both trust and affect is mediated, even reversed, by demographic and cultural variables. Given the potential malleability of perceptions, novel methods for understanding future public responses to nanotechnologies will need to be developed.

Risk perception, risk management and safety assessment: what can governments do to increase public confidence in their vaccine system?

MacDonald, Noni E; Smith, Jennifer; Appleton, Mary

2012-09-01

For decades vaccine program managers and governments have devoted many resources to addressing public vaccine concerns, vaccine risk perception, risk management and safety assessment. Despite ever growing evidence that vaccines are safe and effective, public concerns continue. Education and evidence based scientific messages have not ended concerns. How can governments and programs more effectively address the public's vaccine concerns and increase confidence in the vaccine safety system? Vaccination hesitation has been attributed to concerns about vaccine safety, perceptions of high vaccine risks and low disease risk and consequences. Even when the public believes vaccines are important for protection many still have concerns about vaccine safety. This overview explores how heuristics affect public perception of vaccines and vaccine safety, how the public finds and uses vaccine information, and then proposes strategies for changes in the approach to vaccine safety communications. Facts and evidence confirming the safety of vaccines are not enough. Vaccine beliefs and behaviours must be shaped. This will require a shift in the what, when, how and why of vaccine risk and benefit communication content and practice. A change to a behavioural change strategy such as the WHO COMBI program that has been applied to disease eradication efforts is suggested. Copyright © 2011. Published by Elsevier Ltd..

We assessed the influence of the Fukushima nuclear accident (FNA) on the Chinese public’s attitude and acceptance of nuclear power plants in China. Two surveys (before and after the FNA) were administered to separate subsamples of residents near the Tianwan nuclear power plant in Lianyungang, China. A structural equation model was constructed to describe the public acceptance of nuclear power and four risk perception factors: knowledge, perceived risk, benefit, and trust. Regression analysis was conducted to estimate the relationship between acceptance of nuclear power and the risk perception factors while controlling for demographic variables. Meanwhile, we assessed the median public acceptable frequencies for three levels of nuclear events. The FNA had a significant impact on risk perception of the Chinese public, especially on the factor of perceived risk, which increased from limited risk to great risk. Public acceptance of nuclear power decreased significantly after the FNA. The most sensitive groups include females, those not in public service, those with lower income, and those living close to the Tianwan nuclear power plant. Fifty percent of the survey respondents considered it acceptable to have a nuclear anomaly no more than once in 50 y. For nuclear incidents and serious incidents, the frequencies are once in 100 y and 150 y, respectively. The change in risk perception and acceptance may be attributed to the FNA. Decreased acceptance of nuclear power after the FNA among the Chinese public creates additional obstacles to further development of nuclear power in China and require effective communication strategies.

To assess the differences in risk perceptions of overweight/obese and normal-weight adolescents about obesity and associated risk factors. Qualitative study using focus group discussions (FGDs). Five randomly selected schools from the South Indian city of Hyderabad. Seventy-nine adolescents (ages 11-14 years) participated in 10 FGDs (5 each with overweight/obese and normal-weight groups). Whether obesity-related risk perceptions differ with actual weight status or not. FGDs were recorded, transcribed, and manually coded for thematic analysis. Results were presented according to 6 themes. At each stage of coding and analysis, reports were read independently by 2-3 researchers and the inter-coder reliability was high (ratio of number of agreements against the sum of agreements plus disagreements was over 90%). Adolescents across the groups had limited understanding of nutrition during adolescence as well as causes and consequences of obesity. The optimistic bias that they were less vulnerable compared to others to the risks of obesity was evident from perceptions of overweight groups. While overweight adolescents argued that obesity was hereditary, the normal-weight participants perceived "faulty food habits" and laziness as the reasons. Adolescents across the groups considered fruits and vegetables as healthy foods. There were clear differences in perceptions of adolescents of different weight status. Employing the risk perception analysis framework, this study identified the following adolescent traits: responsive, avoidance, and indifference, which may be useful for developing nutrition communication programs.

The authors evaluated the feasibility of a 1-hour session to ensure competency in gait and falls risk assessment for medical students at their institution. The session included a history and exam with faculty and staff as standardized patients, gait recognition videos, and case evaluation for falls risk assessment and prevention. Student perceptions were evaluated using a retrospective pre-post survey, scored on a 5-point Likert-type scale. Wilcoxon signed-rank tests were used to assess change and Kruskal-Wallis tests were used to analyze differences by residency choice. A range of five to 11 faculty and staff certified 238 medical students during eight 1-hour sessions. Overall self-perception of competence in falls risk assessment and prevention improved (p ≤ .001), and did not differ by residency choice, both before and after the training program (p = .73 and p = .25). Feedback was positive. This session is a feasible way to teach and assess the competency for falls risk assessment with modest time commitment.

Environmental destruction is one of the most important problems in this century. The aim of the study was to determine the environmental attitudes and perceived risks associated with environmental factors of the students. This cross-sectional study was conducted in 7 faculties of Mersin University. The research data were collected using a questionnaire. The questionnaire included sociodemographic characteristics, the "Environmental Attitudes Scale," and the "Environmental Risk Perception Scale." 774 students who filled out questionnaires were evaluated. The sample included 55.8% females. Environmental Attitudes Scale mean scores of students were identified as 81.1 ± 11.3. The highest perceived risk was release of radioactive materials associated with nuclear power generation. The environmental attitudes and risk perception scores were higher in Health Sciences than in the other faculties. Females were more positive towards the environment and had higher risk perceptions than the men. There is a negative correlation between age and resource depletion risk and global environmental risk score. Students had a positive attitude to the environment and had moderate-level risk perception about the environment. Environmental awareness of students, especially those studying in the Social Sciences, should be increased. The environmental education curriculum should be revised throughout all the courses.

Oral anticoagulation (OAC) is state-of-the-art therapy for atrial fibrillation (AF), the most common arrhythmia worldwide. However, little is known about the perception of patients with AF and how it correlates with risk scores used by their physicians. Therefore, we correlated patients' estimates of their own stroke and bleeding risk with the objectively predicted individual risk using CHA 2 DS 2 -VASc and HAS-BLED scores. Cross-sectional prevalence study using convenience sampling and telephone follow-up. Eight hospital departments and one general practitioner in Austria. Patients' perception of stroke and bleeding risk was opposed to commonly used risk scoring. Patients with newly diagnosed AF and indication for anticoagulation. Comparison of subjective risk perception with CHA 2 DS 2 -VASc and HAS-BLED scores showing possible discrepancies between subjective and objective risk estimation. Patients' judgement of their own knowledge on AF and education were also correlated with accuracy of subjective risk appraisal. Ninety-one patients (age 73±11 years, 45% female) were included in this study. Subjective stroke and bleeding risk estimation did not correlate with risk scores (ρ=0.08 and ρ=0.17). The majority of patients (57%) underestimated the individual stroke risk. Patients feared stroke more than bleeding (67% vs 10%). There was no relationship between accurate perception of stroke and bleeding risks and education level. However, we found a correlation between the patients' judgement of their own knowledge of AF and correct assessment of individual stroke risk (ρ=0.24, p=0.02). During follow-up, patients experienced the following events: death (n=5), stroke (n=2), bleeding (n=1). OAC discontinuation rate despite indication was 3%. In this cross-sectional analysis of OAC-naive patients with AF, we found major differences between patients' perceptions and physicians' assessments of risks and benefits of OAC. To ensure shared decision-making and informed consent, more attention should be given to evidence-based and useful communication strategies.

Objective. To assess the effect of communication style, and frequency and severity of medication side-effects, on pharmacy students' perception of risk of experiencing side effects. Methods. One hundred responses from pharmacy students were obtained using an online survey. Participants were presented with a drug information box containing drug name, drug usage, and one side-effect associated with the drug. Information on side-effect for each drug was presented in one of eight experimental conditions, in a 2 (side-effect frequency: low, high), X2 (side-effect severity: mild, severe) X2 (communication style: verbal, verbal + natural frequency) factorial design. Risk perception of experiencing side effects was measured. Results. Communication style was found to have a significant impact on risk perception depending on the context of frequency and severity associated with the side effect. Conclusion. Communication style plays a significant role in formulating risk perceptions of medication side effects. Training in pharmaceutical counseling should include special emphasis on effective language use.

To determine the specific components of family history and personal characteristics related to disease perceptions about breast, colon, and ovarian cancers. Baseline, cross-sectional data on 2,505 healthy women aged 35-65 years enrolled from 41 primary care practices in the cluster-randomized Family Healthware™ Impact Trial, assessed for detailed family history and perceived risk, perceived severity, worry, and perceived control over getting six common diseases including breast, colon, and ovarian cancers. Participants provided family history information on 41,841 total relatives. We found evidence of underreporting of paternal family history and lower perceived breast cancer risk with cancer in the paternal versus maternal lineage. We observed cancer-specific perceived risks and worry for individual family history elements and also found novel "spillover" effects where a family history of one cancer was associated with altered disease perceptions of another. Having a mother with early-onset breast or ovarian cancer was strongly associated with perceived risk of breast cancer. Age, parenthood, and affected lineage were associated with disease perceptions and ran counter to empiric risks. Understanding patients' formulation of risk for multiple diseases is important for public health initiatives that seek to inform risk appraisal, influence disease perceptions, or match preventive interventions to existing risk perceptions.

Wind Speed Perception and Risk

Agdas, Duzgun; Webster, Gregory D.; Masters, Forrest J.

2012-01-01

Background How accurately do people perceive extreme wind speeds and how does that perception affect the perceived risk? Prior research on human–wind interaction has focused on comfort levels in urban settings or knock-down thresholds. No systematic experimental research has attempted to assess people's ability to estimate extreme wind speeds and perceptions of their associated risks. Method We exposed 76 people to 10, 20, 30, 40, 50, and 60 mph (4.5, 8.9, 13.4, 17.9, 22.3, and 26.8 m/s) winds in randomized orders and asked them to estimate wind speed and the corresponding risk they felt. Results Multilevel modeling showed that people were accurate at lower wind speeds but overestimated wind speeds at higher levels. Wind speed perceptions mediated the direct relationship between actual wind speeds and perceptions of risk (i.e., the greater the perceived wind speed, the greater the perceived risk). The number of tropical cyclones people had experienced moderated the strength of the actual–perceived wind speed relationship; consequently, mediation was stronger for people who had experienced fewer storms. Conclusion These findings provide a clearer understanding of wind and risk perception, which can aid development of public policy solutions toward communicating the severity and risks associated with natural disasters.

Predictive factors including risk perception for mid-term mental health after a nuclear disaster remain unknown. The purpose of this study was to examine the association between perceived radiation risk and other factors at baseline and mid-term mental health after the Fukushima Daiichi nuclear disaster of 2011 in Japan. A mail-based questionnaire survey was conducted in January 2012 and January 2013. Mental health status was assessed using the K6 scale. Psychological distress over the 2-year period was categorized into the following four groups: chronic, recovered, resistant, or worsened. Most participants (80.3%) were resistant to the disaster. A positive association was found between the radiation risk perception regarding immediate effects and the worsened group in women. Baseline post-traumatic stress disorder (PTSD) or a history of psychiatric disease predicted being in the chronic or worsened group in mid-term course. These results suggest that evacuees who believed that their health was substantially affected by the nuclear disaster were at an increased risk of having poor mid-term mental health in women. Careful assessment of risk perception after a nuclear disaster, including the presence of PTSD or a history of psychiatric disease, is needed for appropriate interventions. PMID:28914809

The goal of this study was to assess which parenting behaviors, perceptions, and risk factors were associated with optimal versus delayed development. A total of 382 families from the national Brigance Infant and Toddler Screens standardization and validation study participated. Data sources included parent questionnaires, child testing, and examiner observations of parent-child interactions. Parenting styles research was operationalized with the Brigance Parent-Child Interactions Scale, a brief measure of parenting behaviors and perceptions. Six positive parenting behaviors and perceptions predicted average to above-average development on the Brigance screens. Conversely, <2 positive parenting behaviors and negative perceptions of children indicated child performance nearly 2 SDs below the mean on Brigance screens. Psychosocial risk factors associated with fewer positive parenting behaviors and with negative perceptions included >3 children in the home, multiple moves, limited English, and parental depression. A dearth of positive parenting behaviors plus negative perceptions of children, with or without psychosocial risk factors, negatively affect child development, which is apparent as early as 6 months of age. The older the child is, the greater the performance gaps are. Language development is particularly at risk when parenting is problematic. Findings underscore the importance of early development promotion with parents, focusing on their talking, playing, and reading with children, and the need for interventions regarding psychosocial risk factors.

Risk Communication Emergency Response Preparedness: Contextual Assessment of the Protective Action Decision Model.

Studies are continuously performed to improve risk communication campaign designs to better prepare residents to act in the safest manner during an emergency. To that end, this article investigates the predictive ability of the protective action decision model (PADM), which links environmental and social cues, predecision processes (attention, exposure, and comprehension), and risk decision perceptions (threat, alternative protective actions, and stakeholder norms) with protective action decision making. This current quasi-longitudinal study of residents (N = 400 for each year) in a high-risk (chemical release) petrochemical manufacturing community investigated whether PADM core risk perceptions predict protective action decision making. Telephone survey data collected at four intervals (1995, 1998, 2002, 2012) reveal that perceptions of protective actions and stakeholder norms, but not of threat, currently predict protective action decision making (intention to shelter in place). Of significance, rather than threat perceptions, perception of Wally Wise Guy (a spokes-character who advocates shelter in place) correlates with perceptions of protective action, stakeholder norms, and protective action decision making. Wally's response-efficacy advice predicts residents' behavioral intentions to shelter in place, thereby offering contextually sensitive support and refinement for PADM. © 2017 Society for Risk Analysis.

This is a descriptive study examining nursing students' perceptions of the environmental risks and their environmental attitudes. The study population comprised 2364 nursing students studying at universities in Istanbul in the fall semester of the 2012-2013 academic year. The sampling group was formed by 778 students which were selected by a stratified random sampling procedure. The data were collected using "The Student Personal Information Form", "The Environmental Risk Perception Scale" and "The Environmental Attitudes Scale". The students' mean score on perceptions of environmental risk was 6.04 ± 0.81(min 2.56; max 7.00) and the mean score of their environmental attitudes was 4.02 ± 0.47(min 2.28; max 5.00). It was determined that factors such as gender, interest in environmental issues, endorsement of the college course on environment as necessary, and participation in an environmental activity and awareness of non-government environmental organizations affected the environmental risk perception and environmental attitudes. A moderate positive relationship (r = 0.366, p < .001) was found between the students' environmental risk perceptions and their environmental attitudes. Effective environmental education should be planned at all stages of the nursing education.

Objectives Falls are a leading cause of injury at work, and slipping is the predominant cause of falling. Prior research has suggested a modest correlation between objective measures (such as coefficient of friction, COF) and subjective measures of slipperiness (such as worker perceptions) in the workplace. However, the degree of association between subjective measures and the actual risk of slipping at the workplace is unknown. This study examined the association between perception of slipperiness and the risk of slipping. Methods 475 workers from 36 limited-service restaurants participated in a 12-week prospective cohort study. At baseline, demographic information was collected, participants rated floor slipperiness in eight areas of the restaurant, and work environment factors, such as COF, were measured. Restaurant-level and area-level mean perceptions of slipperiness were calculated. Participants then reported their slip experience at work on a weekly basis for the next 12 weeks. The associations between perception of slipperiness and the rate of slipping were assessed. Results Adjusting for age, gender, body mass index, education, primary language, mean COF, use of slip-resistant shoes, and restaurant chain, each 1-point increase in mean restaurant-level perception of slipperiness (4-point scale) was associated with a 2.71 times increase in the rate of slipping (95% CI 1.25 to 5.87). Results were similar for area-level perception within the restaurant (rate ratios (RR) 2.92, 95% CI 2.41 to 3.54). Conclusions Perceptions of slipperiness and the subsequent rate of slipping were strongly associated. These findings suggest that safety professionals, risk managers and employers could use aggregated worker perceptions of slipperiness to identify slipping hazards and, potentially, to assess intervention effectiveness.

The objective of this study is to examine risk taking and risk perception associations with perceived exertion, pacing, and performance in athletes. Two experiments were conducted in which risk perception was assessed using the domain-specific risk taking (DOSPERT) scale in 20 novice cyclists (experiment 1) and 32 experienced ultramarathon runners (experiment 2). In experiment 1, participants predicted their pace and then performed a 5-km maximum effort cycling time trial on a calibrated Kingcycle mounted bicycle. Split times and perceived exertion were recorded every kilometer. In experiment 2, each participant predicted their split times before running a 100-km ultramarathon. Split times and perceived exertion were recorded at seven checkpoints. In both experiments, higher and lower risk perception groups were created using median split of DOSPERT scores. In experiment 1, pace during the first kilometer was faster among lower risk perceivers compared with higher risk perceivers (t(18) = 2.0, P = 0.03) and faster among higher risk takers compared with lower risk takers (t(18) = 2.2, P = 0.02). Actual pace was slower than predicted pace during the first kilometer in both the higher risk perceivers (t(9) = -4.2, P = 0.001) and lower risk perceivers (t(9) = -1.8, P = 0.049). In experiment 2, pace during the first 36 km was faster among lower risk perceivers compared with higher risk perceivers (t(16) = 2.0, P = 0.03). Irrespective of risk perception group, actual pace was slower than predicted pace during the first 18 km (t(16) = 8.9, P < 0.001) and from 18 to 36 km (t(16) = 4.0, P < 0.001). In both experiments, there was no difference in performance between higher and lower risk perception groups. Initial pace is associated with an individual's perception of risk, with low perceptions of risk being associated with a faster starting pace. Large differences between predicted and actual pace suggest that the performance template lacks accuracy, perhaps indicating greater reliance on momentary pacing decisions rather than preplanned strategy.

One factor women consider when deciding whether to pursue amniocentesis is the risk of miscarriage. People use mechanisms like anchoring, or the prior belief regarding the magnitude of risk, as a frame of reference for new information. This study aimed to determine a woman's perception of miscarriage risk associated with amniocentesis before and after genetic counseling and to determine what factors anchor a woman's perception of miscarriage risk. One hundred thirteen women being seen for prenatal genetic counseling and possible amniocentesis at six Houston clinics participated in the two-part anonymous survey. While most women (56.7 %) perceived the risk as low or average pre-counseling and indicated the numeric risk of amniocentesis as <1 %, significantly more patients (73 %) correctly identified the numeric risk as <1 % post-counseling (p < 0.0001). However, the majority of patients' qualitative risk perception did not change after the genetic counseling session (60 %). Those who changed their feeling about the risk after counseling showed a decreased perception of the risk (p < 0.0001). Participants who elected amniocentesis had a significantly lower perception of the risk (p = 0.017) whereas those who declined amniocentesis were more likely to view the risk as high (p = 0.004). The only two anchoring factors that had an effect were having a friend or relative with a personal or family history of a genetic disorder (p = 0.001) and having a child already (p = 0.038); both were associated with a lower risk perception. The lack of significant factors may reflect the uniqueness of each patient's risk assessment framework and reinforces the importance of genetic counseling to elucidate individual concerns, particularly as non-invasive prenatal testing becomes more widely available and further complicates the prenatal testing landscape.

This study used a new Crime Prevention Through Environmental Design (CPTED) assessment tool to test the associations between physical attributes of schools and violence-related behaviors and perceptions of students. Data were collected from 4717 students from 50 middle schools. Student perceptions of risk and safety, and violence were assessed. Evaluators used the CPTED School Assessment (CSA) to quantify how well the physical elements of each school correspond to ideal CPTED principles. Generalized linear mixed models were used to adjust for school- and student-level characteristics. Higher CSA scores were generally associated with higher perceptions of safety and lower levels of violence perpetration and perceived risk in unadjusted models. Higher CSA scores were also associated with lower odds of missing school because of safety concerns in most adjusted models, with significant adjusted odds ratios (AORs) ranging from 0.32 to 0.63. CSA scores for parking and bus loading areas also remained associated with higher perceived safety (AORs = 1.28 and 1.32, respectively) and lower perceived risk (AORs = 0.73 and 0.66, respectively) in adjusted models. The CSA is useful for assessing school environments that are associated with violence-related behaviors and perceptions. The CSA might help guide school environmental modifications to reduce violence. © 2018, American School Health Association.

The present study assessed the degree to which probabilistic reasoning performance and thinking style influenced perception of risk and self-reported levels of terrorism-related behavior change. A sample of 263 respondents, recruited via convenience sampling, completed a series of measures comprising probabilistic reasoning tasks (perception of randomness, base rate, probability, and conjunction fallacy), the Reality Testing subscale of the Inventory of Personality Organization (IPO-RT), the Domain-Specific Risk-Taking Scale, and a terrorism-related behavior change scale. Structural equation modeling examined three progressive models. Firstly, the Independence Model assumed that probabilistic reasoning, perception of risk and reality testing independently predicted terrorism-related behavior change. Secondly, the Mediation Model supposed that probabilistic reasoning and reality testing correlated, and indirectly predicted terrorism-related behavior change through perception of risk. Lastly, the Dual-Influence Model proposed that probabilistic reasoning indirectly predicted terrorism-related behavior change via perception of risk, independent of reality testing. Results indicated that performance on probabilistic reasoning tasks most strongly predicted perception of risk, and preference for an intuitive thinking style (measured by the IPO-RT) best explained terrorism-related behavior change. The combination of perception of risk with probabilistic reasoning ability in the Dual-Influence Model enhanced the predictive power of the analytical-rational route, with conjunction fallacy having a significant indirect effect on terrorism-related behavior change via perception of risk. The Dual-Influence Model possessed superior fit and reported similar predictive relations between intuitive-experiential and analytical-rational routes and terrorism-related behavior change. The discussion critically examines these findings in relation to dual-processing frameworks. This includes considering the limitations of current operationalisations and recommendations for future research that align outcomes and subsequent work more closely to specific dual-process models.

Communication of lung cancer risk information between providers and African-American patients occurs in a context marked by race-based health disparities. A controlled experiment assessed whether perceived physician race influenced African-American patients' (n = 127) risk perception accuracy following the provision of objective lung cancer risk information. Participants interacted with a virtual reality-based, simulated physician who provided personalized cancer risk information. Participants who interacted with a racially discordant virtual doctor were less accurate in their risk perceptions at post-test than those who interacted with a concordant virtual doctor, F(1,94) = 4.02, p = .048. This effect was amplified among current smokers. Effects were not mediated by trust in the provider, engagement with the health care system, or attention during the encounter. The current study demonstrates that African-American patients' perceptions of a doctor's race are sufficient to independently impact their processing of lung cancer risk information.

This study assessed the perception of risk of cervical cancer and existence of risk factors for cervical cancer based on five known risk factors among women attending the Tamale Teaching Hospital in Tamale, Ghana. A consecutive sample of 300 women was interviewed using a semi-structured questionnaire to inquire about risk factors and perception of risk of cervical cancer. Specific risk factors that were explored included early coitarche, multiple sexual partners, polygamous relationships, history of smoking, and having a current partner who had multiple sexual partners. Sixty-one per cent of women reported that they had no personal risk for cervical cancer. 27% of respondents were in polygamous relationships, and of those, more than half didn't think they were at an increased risk of cervical cancer. 2 women had a total of ≥ 5 sexual partners in their lifetime and neither believed they were at any risk for cervical cancer. 23% said their current partner had had at least 2 sexual partners in his lifetime, and of those, (61%) thought they were at no risk for cervical cancer. 46% of respondents reported not having any of the risk factors listed in the study. 23% of respondents reported having one risk factor while 21% had two risk factors and 11% had three or more risk factors. Women's perception of personal risk for cervical cancer is lower than their actual risk based on the five behavioural risk factors assessed and a lack of knowledge of the personal factors for the disease. This project was supported by NIH Research Training Grant #R25 TW009345 funded by the Fogarty International Centre, in partnership with several NIH Institutes (NIMH, NIGMS, NHLBI, OAR and OWH).

Skewed risk perceptions in pregnant women: the case of influenza vaccination.

Pregnant women and their newborns have an increased risk of developing severe influenza and influenza-related complications. In Germany, seasonal influenza vaccination is recommended for pregnant women since 2010. However, little is known about pregnant women's vaccination-related knowledge and attitudes, as well as their risk perceptions. This study therefore assessed pregnant women's vaccination-related knowledge, risk perceptions related to influenza disease and influenza vaccination during pregnancy, and aimed to identify determinants of influenza vaccination uptake during pregnancy in Germany. Between 2012 and 2014, a nationwide web-based prospective cohort study with follow-up interviews was conducted in initially pregnant women who gave birth over the study period. Control groups were set up in a cross-sectional fashion during the follow-up interviews. Women who participated in both, the baseline interview before giving birth and in the 1st interview after giving birth were included in the analysis. Univariate and multiple logistic regression were used to identify associations between influenza vaccination uptake and sociodemographic characteristics as well as items assessing attitude and knowledge. In total, 838 women were included in the analyses. Pregnant women had a positive attitude towards vaccination in general, but only modest vaccination knowledge. Overall, 10.9 % of women were vaccinated against seasonal influenza during pregnancy. While pregnant women perceived classical childhood diseases to be more risky than the respective vaccinations, this relation reversed for influenza: The risk of vaccination was perceived higher than the risk of the disease. These two types of risk perceptions independently determined influenza vaccination uptake-higher perception of disease risk and lower perceptions of vaccination-related risks increased uptake. Additionally, knowledge about the vaccination recommendation for pregnant women and a positive gynaecologist's attitude towards vaccination during pregnancy influenced the uptake significantly. Influenza vaccination uptake in pregnant women is low in Germany. Tailored communication strategies for pregnant women should focus especially on changing the perceptions of personal risks regarding influenza and influenza vaccination during pregnancy. Gynaecologists should be made aware about their crucial role in supporting vaccination decision-making of pregnant women and the need to provide relevant information to counteract misconceptions.

Hepatitis B virus (HBV) Infection is endemic in Nigeria. Healthcare students are more vulnerable because of direct contact with patients' body fluids and blood. Risk perception of HBV and HB vaccine uptake are also poor. The aim of this study was to assess the level of risk perception of hepatitis B infection, and uptake of the HBV vaccine, between medical and other students of the University of Jos. A comparative cross sectional study was conducted among 1,200 students of the departments of Medicine, Nursing sciences and Public Administration, University of Jos (400 from each arm) using a pretested self-administered questionnaire. A five point Likert scoring system was used to assess risk perception. Data was analyzed using SPSS version 20. A P -value of <0.05 was considered significant. Awareness on HB vaccine prevention was high (88.4%) among University of Jos students. Awareness was similar among medical and nursing students (36.2% and 36.0% respectively) but lower among public administration student (27.8%), P< 0.001. The overall risk perception was 76.8%. This was also similar for medical and nursing students (40.7% and 40.1% respectively), but lower for public administration students (9.1%), P< 0.001. Risk perception is 5x higher among medical students compared to public administration students (OR = 5.22, 95% CI = 2.19 - 12.93; P < 0.001). The uptake of full dose HB vaccine was 60.2%, 20.6% and 15.1% for medical, nursing and public administration students respectively. Medical students are 4x more likely to go for HB vaccination compared with public administration students (OR=3.62; 95% CI=2.39 - 5.48; P< 0.001). Awareness and risk perception on HBV infection are high among University of Jos students, but uptake of HB vaccine is low. Findings are worst for non-health students.

In the wake of the 2011 Fukushima Daiichi Nuclear Power Station accident, to facilitate evidence-based risk communication we need to understand radiation risk perception and the effectiveness of risk-comparison information. We measured and characterized perceptions of dread risks and unknown risks regarding dietary radionuclides in residents of Fukushima, Tokyo, and Osaka to identify the primary factors among location, evacuation experience, gender, age, employment status, absence/presence of spouse, children and grandchildren, educational background, humanities/science courses, smoking habits, and various types of trustworthy information sources. We then evaluated the effects of these factors and risk-comparison information on multiple outcomes, including subjective and objective understanding, perceived magnitude of risk, perceived accuracy of information, backlash against information, and risk acceptance. We also assessed how risk-comparison information affected these multiple outcomes for people with high risk perception. Online questionnaires were completed by people (n = 9249) aged from 20 to 69 years in the three prefectures approximately 5 years after the accident. We gave each participant one of 15 combinations of numerical risk data and risk-comparison information, including information on standards, smoking-associated risk, and cancer risk, in accordance with Covello's guidelines. Dread-risk perception among Fukushima residents with no experience of evacuation was much lower than that in Osaka residents, whereas evacuees had strikingly higher dread-risk perception, irrespective of whether their evacuation had been compulsory or voluntary. We identified location (distance from the nuclear power station), evacuation experience, and trust of central government as primary factors. Location (including evacuation experience) and trust of central government were significantly associated with the multiple outcomes above. Only information on "cancer risk from radiation and smoking risk" enhanced both subjective and objective understanding without diminishing trust in all participants and in the high dread-risk perception group; use of other risk-comparison information could lead the public to overestimate risk.

Public traffic safety campaigns in Germany have focussed on the changing risk perception of young drivers. While there is some consensus that perceptions of risk affect driving, less is understood about the relationship and interaction of alcohol consumption and risk perception on the decision to drive. We examined the influence of light alcohol consumption on risk perception and decision to drive, and the interaction of alcohol consumption and cognitive feedback on the handicapping effect of alcohol on risk perception and decision to drive. In a double-blind block-randomized experimental study of 104 young drivers between 19 and 24 years of age, with two experimentally manipulated independent factors of alcohol consumption (three levels: 0% BAC, 0.015% BAC, 0.03% BAC) and feedback (positive or negative), we assessed three dependent variables: perception of traffic accident risk, subjective judgement about driving-relevant cognitive performance, decision to drive a car. Analyses of variance and covariance were used to analyze differences between levels of experimental factors. We found that persons with 0.015 BAC performed better than persons in both other alcohol conditions on the standardized risk perception task. Perceived handicap of driving was significantly more pronounced for negative feedback compared to positive feedback with no influence of the level of alcohol consumption. No significant influence on decision to drive was found of either level of alcohol consumption, feedback or sex. Decision to drive in young drivers could not be influenced by feedback or light consumption. Public health approaches have to find better determining factors.

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

In the wake of the 2011 Fukushima Daiichi Nuclear Power Station accident, to facilitate evidence-based risk communication we need to understand radiation risk perception and the effectiveness of risk-comparison information. We measured and characterized perceptions of dread risks and unknown risks regarding dietary radionuclides in residents of Fukushima, Tokyo, and Osaka to identify the primary factors among location, evacuation experience, gender, age, employment status, absence/presence of spouse, children and grandchildren, educational background, humanities/science courses, smoking habits, and various types of trustworthy information sources. We then evaluated the effects of these factors and risk-comparison information on multiple outcomes, including subjective and objective understanding, perceived magnitude of risk, perceived accuracy of information, backlash against information, and risk acceptance. We also assessed how risk-comparison information affected these multiple outcomes for people with high risk perception. Online questionnaires were completed by people (n = 9249) aged from 20 to 69 years in the three prefectures approximately 5 years after the accident. We gave each participant one of 15 combinations of numerical risk data and risk-comparison information, including information on standards, smoking-associated risk, and cancer risk, in accordance with Covello’s guidelines. Dread-risk perception among Fukushima residents with no experience of evacuation was much lower than that in Osaka residents, whereas evacuees had strikingly higher dread-risk perception, irrespective of whether their evacuation had been compulsory or voluntary. We identified location (distance from the nuclear power station), evacuation experience, and trust of central government as primary factors. Location (including evacuation experience) and trust of central government were significantly associated with the multiple outcomes above. Only information on “cancer risk from radiation and smoking risk” enhanced both subjective and objective understanding without diminishing trust in all participants and in the high dread-risk perception group; use of other risk-comparison information could lead the public to overestimate risk.

Genetics and mental health professionals increasingly provide education and counseling related to risk for psychiatric illness, but there is insufficient evidence about patient perceptions and needs to guide such interventions. Affected individuals and relatives may perceive increased family risk and have interest in genetic education and counseling. Our objectives were to explore perceptions of family vulnerability, perceived control, and coping strategies related to familial risk and needs from genetic counseling. Our methods included conducting semi-structured interviews (n = 48) with individuals with bipolar disorder (BPD) and unaffected siblings. Content analysis generated descriptive data that provide guidance for clinical interventions and themes to evaluate in future studies. The results showed that participants perceived increased personal and family risk, attributing BPD to genes and family environment. Causal attributions were often uncertain and at times inconsistent. Participants wished to modify psychiatric risk to relatives, but were uncertain how to do so; despite the uncertainty, most parents reported risk-modification efforts. Efforts to cope with family vulnerability included monitoring and cognitive distancing. Participants endorsed the usefulness of education and psychological support, but described more ambivalence about receiving risk assessment. Educational and supportive interventions around family risk for BPD should focus on perceptions of cause and vulnerability, reproductive decision-making, and early intervention and risk modification in young relatives. Psychological support is an important component. Providers should evaluate patient coping strategies, which could facilitate or hinder genetic counseling interventions, and should not assume interest in quantitative risk assessment. 2009 Wiley-Liss, Inc.

This study examines the influence of mass media, interpersonal communication, and elaborative processing on public perception of benefits and risks of nanotechnology, based on a large-scale nationally representative telephone survey of U.S. adult citizens. Results indicate that cognitive processes in the form of news elaboration had a significant positive main effect on benefits outweigh risks perception. The influences of attention to science in newspapers, attention to science news on television, and interpersonal communication about science on public perception of benefits outweigh risks were moderated by elaborative processing, after controlling for socio-demographic variables, religious beliefs, trust in scientists, and scientific knowledge. The findings highlight the importance of elaborative processing when it comes to understanding how the mass media differentially influence public benefits outweigh risks perception of emerging technologies. Specifically, high elaborative processing emphasizes higher levels of perceived benefits outweigh risks than low elaborative processing. This study explores explanations for this phenomenon and offers implications for future research and policy.

The aims of this study were to adapt the Job Factors Questionnaire to the field of dentistry, evaluate its psychometric properties, evaluate dental students' perceptions of work/study risk factors for musculoskeletal disorders, and determine the influence of gender and academic level on those perceptions. All 580 students enrolled in two Brazilian dental schools in 2015 were invited to participate in the study. A three-factor structure (Repetitiveness, Work Posture, and External Factors) was tested through confirmatory factor analysis. Convergent validity was estimated using the average variance extracted (AVE), discriminant validity was based on the correlational analysis of the factors, and reliability was assessed. A causal model was created using structural equation modeling to evaluate the influence of gender and academic level on students' perceptions. A total of 480 students completed the questionnaire for an 83% response rate. The responding students' average age was 21.6 years (SD=2.98), and 74.8% were women. Higher scores were observed on the Work Posture factor items. The refined model presented proper fit to the studied sample. Convergent validity was compromised only for External Factors (AVE=0.47), and discriminant validity was compromised for Work Posture and External Factors (r 2 =0.69). Reliability was adequate. Academic level did not have a significant impact on the factors, but the women students exhibited greater perception. Overall, the adaptation resulted in a useful instrument for assessing perceptions of risk factors for musculoskeletal disorders. Gender was found to significantly influence all three factors, with women showing greater perception of the risk factors.

Background Environmental destruction is one of the most important problems in this century. Objective The aim of the study was to determine the environmental attitudes and perceived risks associated with environmental factors of the students. Methods This cross-sectional study was conducted in 7 faculties of Mersin University. The research data were collected using a questionnaire. The questionnaire included sociodemographic characteristics, the “Environmental Attitudes Scale,” and the “Environmental Risk Perception Scale.” 774 students who filled out questionnaires were evaluated. Results The sample included 55.8% females. Environmental Attitudes Scale mean scores of students were identified as 81.1 ± 11.3. The highest perceived risk was release of radioactive materials associated with nuclear power generation. The environmental attitudes and risk perception scores were higher in Health Sciences than in the other faculties. Females were more positive towards the environment and had higher risk perceptions than the men. There is a negative correlation between age and resource depletion risk and global environmental risk score. Conclusion Students had a positive attitude to the environment and had moderate-level risk perception about the environment. Environmental awareness of students, especially those studying in the Social Sciences, should be increased. The environmental education curriculum should be revised throughout all the courses.

Purpose To determine the specific components of family history and personal characteristics related to disease perceptions about breast, colon, and ovarian cancers. Methods Baseline, cross-sectional data on 2,505 healthy women aged 35–65 years enrolled from 41 primary care practices in the cluster-randomized Family Healthware™ Impact Trial, assessed for detailed family history and perceived risk, perceived severity, worry, and perceived control over getting six common diseases including breast, colon, and ovarian cancers. Results Participants provided family history information on 41,841 total relatives. We found evidence of underreporting of paternal family history and lower perceived breast cancer risk with cancer in the paternal versus maternal lineage. We observed cancer-specific perceived risks and worry for individual family history elements and also found novel “spillover” effects where a family history of one cancer was associated with altered disease perceptions of another. Having a mother with early-onset breast or ovarian cancer was strongly associated with perceived risk of breast cancer. Age, parenthood, and affected lineage were associated with disease perceptions and ran counter to empiric risks. Conclusions Understanding patients' formulation of risk for multiple diseases is important for public health initiatives that seek to inform risk appraisal, influence disease perceptions, or match preventive interventions to existing risk perceptions.

A descriptive-correlational study of biosolids recycling was conducted in the south-eastern United States to assess current knowledge, attitudes and risk perceptions of participants in two communities that land apply biosolids as part of their waste management programs. One community, Amelia County VA, has been outspoken against biosolids recycling in the past, whereas the second community, Knoxville, TN region, has voiced few concerns about biosolids recycling. Additionally, gender differences within the entire study population were assessed. A 45-question telephone survey, utilizing a 4-point Likert scale, was developed and administered to 311 randomly selected adults in the two regions. Commonalities identified during the study revealed key risk perceptions by the public regarding biosolids regulations, treatment, and application. Given current perceptions and knowledge, respondents felt that the benefits derived from biosolids recycling do not offset the perceived health and safety risks. However, as distance between application and personal property increased, a decrease in opposition of biosolids reuse became evident for all respondents. Survey participants were dissatisfied with the level of stakeholder involvement in research and decision-making processes concerning biosolids. The outspoken Amelia County residents perceived greater health risks due to inadequate treatment of biosolids and odorous emissions during the application process than the less engaged Knox Metro respondents. Significant gender differences were observed with sampled females perceiving greater risks to health and safety from biosolids recycling than males. There was also indication that decisions and risks were not sufficiently communicated to the public, leading to respondents being inadequately informed about biosolids land application in both communities. Community-specific outreach programs must address these public risk perceptions and the differences in perception caused by gender and issue awareness to assist solid waste managers in developing and implementing successful biosolids land application systems that are acceptable to the public.

Applying the health action process approach (HAPA) to vaccination behaviour as a single-event health behaviour to study vaccination adherence and its predictors in a worksite flu vaccination programme. A total of N = 823 employees participated in a longitudinal survey. Predictors (risk perception, self-efficacy, positive and negative outcome expectancies, intention and planning) were assessed at Time 1, and behaviour was assessed five months later at Time 2. Intention and planning were specified as mediators in a path analytical logistic regression model. Risk perception, self-efficacy and positive as well as negative outcome expectancies predicted intention (R² = .76). Intention and planning predicted subsequent behaviour, and planning mediated the relation between intention and vaccination behaviour (R² = .67). In addition, results suggested the adjustment of the theoretical model: risk perception and negative outcome expectancies showed direct effects on behaviour resulting in a significantly better model fit. Findings support the general applicability of the HAPA to vaccination behaviour and the importance of planning for translating intentions into behaviour. However, the adjusted model was superior and underlined the particular role of risk perception and negative outcome expectancies for vaccination behaviour to explain underlying mechanisms in vaccination behaviour.

The aim of this study is to analyze the subjective perception of risks for rural workers in Abruzzo, an area of central Italy. A group of 273 workers were asked to fill in a questionnaire which included, apart from general information, questions relative to six different types of risks normally found in the field of agriculture. The types of risks considered were: falling from a height, manually moving loads, overturning/accident whilst driving an agricultural tractor, noise and vibration, use of pesticides, the risk of being cut/injured. The workers were requested to assess, on a scale of 1 to 3, both the probability of an accident taking place and the consequent damage which could result from each of the risks considered. The assessment of the risks provided by the workers was related to the objective assessment of the risks carried out by the study group, also on the basis of objective data provided by INAIL (Italian insurance company) indexes, to highlight the eventual under/over estimations of risk. Furthermore, the possible correlation was evaluated between having received specific training regarding work safety and the workers perception of the risk. The results showed that approximately 11 percent of the workers do not consider their job as being dangerous; the risk perceived by the workers is higher for accidents that cause an immediate injury compared to those which cause professional illnesses, except the risk deriving from noise/vibrations. A direct correlation was found between the job as being dangerous and having attended courses on accident prevention.

False consensus and adolescent peer contagion: examining discrepancies between perceptions and actual reported levels of friends' deviant and health risk behaviors.

Adolescents' perceptions of their friends' behavior strongly predict adolescents' own behavior, however, these perceptions often are erroneous. This study examined correlates of discrepancies between adolescents' perceptions and friends' reports of behavior. A total of 120 11th-grade adolescents provided data regarding their engagement in deviant and health risk behaviors, as well as their perceptions of the behavior of their best friend, as identified through sociometric assessment. Data from friends' own report were used to calculate discrepancy measures of adolescents' overestimations and estimation errors (absolute value of discrepancies) of friends' behavior. Adolescents also completed a measure of friendship quality, and a sociometric assessment yielding measures of peer acceptance/rejection and aggression. Findings revealed that adolescents' peer rejection and aggression were associated with greater overestimations of friends' behavior. This effect was partially mediated by adolescents' own behavior, consistent with a false consensus effect. Low levels of positive friendship quality were significantly associated with estimation errors, but not overestimations specifically.

To assess the impact of plain packaging with larger graphic health warnings on perceptions of risk and prestige related to different cigarette brands among Aboriginal and Torres Strait Islander people in the Australian Capital Territory. We hypothesised that the changes would decrease perceptions that 'some cigarette brands are more harmful than others', and that 'some brands are more prestigious than others', and this would be stronger among participants aged ≤35 years, and among smokers compared with non-smokers. Participants completed the survey prior to packaging changes, and were followed up 12 months later (n=98). Repeated measures ANCOVAs assessed perception changes. Following plain packaging implementation, there was a significant reduction in perceptions that 'some cigarette brands are more harmful than others'. There was no overall change in perceptions of prestige. However, there was a significant interaction for age. Analyses indicated a reduction in perceptions that 'some cigarette brands are more prestigious than others' among younger participants (p=0.05), but no change among older participants (p>0.20). There was no interaction for smoking status for perceptions of prestige, indicating smokers' and non-smokers' perceptions did not differ on this measure. These findings provide support for the packaging changes. © 2015 Public Health Association of Australia.

'Map your Hazards' is an educational module developed within the NSF Interdisciplinary Teaching about Earth for a Sustainable Future program (InTeGrate). The module engages students in place-based explorations of natural hazards, social vulnerability, and the perception of natural hazards and risk. Students integrate geoscience and social science methodologies to (1) identify and assess hazards, vulnerability and risk within their communities; (2) distribute, collect and evaluate survey data (designed by authors) on the knowledge, risk perception and preparedness within their social networks; and (3) deliver a PPT presentation to local stakeholders detailing their findings and recommendations for development of a prepared, resilient community. 'Map your Hazards' underwent four rigorous assessments by a team of geoscience educators and external review before being piloted in our classrooms. The module was piloted in a 300-level 'Volcanoes and Society' course at Boise State University, a 300-level 'Environmental Sociology' course at Central Washington University, and a 100-level 'Natural Disasters and Environmental Geology' course at the College of Western Idaho. In all courses students reported a fascination with learning about the hazards around them and identifying the high risk areas in their communities. They were also surprised at the low level of knowledge, inaccurate risk perception and lack of preparedness of their social networks. This successful approach to engaging students in an interdisciplinary, place-based learning environment also has the broad implications of raising awareness of natural hazards (survey participants are provided links to local hazard and preparedness information). The data and preparedness suggestions can be shared with local emergency managers, who are encouraged to attend the student's final presentations. All module materials are published at serc.carleton.edu/integrate/ and are appropriate to a wide range of classrooms.

The sanitary waste represents a potential hazard for health workers. Given the high risk of infection in labor accidents, the correct management of sanitary waste minimizes this risk and improves labor and environment conditions. To identify risk perception with health professionals in relation to the advanced sorting and management of healthcare waste (HW). The current study is a descriptive, cross-sectional. The sample size was 177 health workers (nurse assistants, nurses, physicians, lab technicians) from three hospitals in Barcelona (Catalonia). Homemade questionnaire and questions with a free and spontaneous association and incomplete sentences were used to analyze labor variables, perception of risk and personal security through a Likert scale. Using a score from 1 (the lowest perception of risk) to 5 (the high perception of risk) to assess the risk perception, the average value for nurse assistants, nurses, physicians, and lab technicians was 3.71, 3.75, 3.83 and 4.03, respectively. Referring to items with free and spontaneous response association, 44.8% of workers consider HW as a biohazard, 29.6% consider it as waste material, 22.1% state that it must be managed properly and 3.5% described it as unknown residues. The results suggest that all health professionals generally have a perception of high risk. The lab technicians have a higher perception of the real risk of inadequate management of HW A 63.2% report that everyone has to make a proper management to preserve their occupational health; the 59% consider that the HW are a biological risk to the general population and only the 47.8% that are harmful to public health. Although it should be noted that only 44.8% think that HW are toxic and dangerous.

HIV risk perceptions are a key determinant of HIV testing. The success of efforts to achieve an AIDS-free generation - including reaching the UNAIDS 90-90-90 target - thus depends critically on the content of these perceptions. We examined the accuracy of HIV-risk perceptions and their correlates among young black women in South Africa, a group with one of the highest HIV incidence rates worldwide. We used individual-level longitudinal data from the Cape Area Panel Study (CAPS) from 2005 to 2009 on black African women (20-30 years old in 2009) to assess the association between perceived HIV-risk in 2005 and the probability of testing HIV-positive four years later. We then estimated multivariable logistic regressions using cross-sectional data from the 2009 CAPS wave to assess the relationship between risk perceptions and a wide range of demographic, sexual behaviour and psychosocial covariates of perceived HIV-risk. We found that the proportion testing HIV-positive in 2009 was almost identical across perceived risk categories in 2005 (no, small, moderate, great) (χ 2  = 1.43, p = 0.85). Consistent with epidemiologic risk factors, the likelihood of reporting moderate or great HIV-risk perceptions was associated with condom-use (aOR: 0.57; 95% CI: 0.36, 0.89; p < 0.01); having ≥3 lifetime partners (aOR: 2.38, 95% CI: 1.53, 3.73; p < 0.01); knowledge of one's partner's HIV status (aOR: 0.67; 95% CI: 0.43, 1.07; p = 0.09); and being in an age-disparate partnerships (aOR: 1.73; 95% CI: 1.09, 2.76; p = 0.02). However, the likelihood of reporting moderate or great self-perceived risk did not vary with sexually transmitted disease history and respondent age, both strong predictors of HIV risk in the study setting. Risk perceptions were associated with stigmatising attitudes (aOR: 0.53; 95% CI: 0.26, 1.09; p = 0.09); prior HIV testing (aOR: 0.21; 95% CI: 0.13, 0.35; p < 0.01); and having heard that male circumcision is protective (aOR: 0.38; 95% CI: 0.22, 0.64; p < 0.01). Results indicate that HIV-risk perceptions are inaccurate. Our findings suggest that this inaccuracy stems from HIV-risk perceptions being driven by an incomplete understanding of epidemiological risk and being influenced by a range of psycho-social factors not directly related to sexual behaviour. Consequently, new interventions are needed to align perceived and actual HIV risk.

Skin cancer risk perceptions: a comparison across ethnicity, age, education, gender, and income.

Studies of noncutaneous and cutaneous malignancies support the hypothesis that poor risk-perception status contributes to health disparity. We evaluated skin cancer (SC) risk perceptions across race and other demographic markers using the Health Information National Trends Survey (HINTS) and compared them to discover differences in perception that may contribute to the disparities in SC diagnosis and treatment. Respondents with no history of SC were randomly selected to answer questions assessing perceived risk and knowledge of preventive strategies of SC. Logistic regression was performed to identify associations between perceptions of SC and demographic variables including self-described race, age, sex, education, income, and health insurance status. Blacks, the elderly, and people with less education perceived themselves as at lower risk of developing SC. They, along with Hispanics, were also more likely to believe that one cannot lower their SC risk and that there are so many different recommendations on how to prevent SC that it makes it difficult to know which ones to follow. Lower education also correlated with greater reluctance to have a skin examination. HINTS is a cross-sectional instrument, thus it only provides a snapshot of SC perceptions. Uncertainty and altered perceptions are more common in the SC risk perceptions of ethnic minorities, the elderly, and those with less education. These are the same groups that are subject to disparities in SC outcomes. Educational programs directed at these demographic groups may help to reduce the SC-related health disparities.

The present prospective study explored whether a specific class of client subjective assessments predicts later recovery. Measures of client perceptions of self-change in substance abusers were obtained a year after release from a prison-based therapeutic community. Analyses assessed the contribution of these perceptions-along with motivation, age, and risk index of social deviancy-in predicting reincarceration at 3-year follow-up. Results showed that two factors (Individual Growth and Socialization) significantly differentiated reincarceration and nonreincarceration at 1-year postrelease and significantly predicted reincarceration at 3-year follow-up. Findings underscore the relevance of perceptions of self-change early in recovery to later recovery behaviors. Research on recovery factors needs a uniform assessment protocol, which organizes client perceptions, beliefs, and attributions in accordance with a recovery stage framework.

Although perceived risk is central to most theories of health behavior, there is little consensus on its measurement with regard to item wording, response set, or the number of items to include. In a methodological assessment of perceived risk, we assessed the impact of changing the order of three commonly used perceived risk items: quantitative personal risk, quantitative population risk, and comparative risk. Participants were 432 men and women enrolled in an ancillary study of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. Three groups of consecutively enrolled participants responded to the three items in one of three question orders. Results indicated that item order was related to the perceived risk ratings of both ovarian (P < 0.05) and colorectal (P < 0.05) cancers. Perceptions of risk were significantly lower when the comparative rating was made first. The findings suggest that compelling participants to consider their own risk relative to the risk of others results in lower ratings of perceived risk. Although the use of multiple items may provide more information than when only a single method is used, different conclusions may be reached depending on the context in which an item is assessed.

To determine how surgeons' perceptions of treatment risks and benefits influence their decisions to operate. Little is known about what makes one surgeon choose to operate on a patient and another chooses not to operate. Using an online study, we presented a national sample of surgeons (N = 767) with four detailed clinical vignettes (mesenteric ischemia, gastrointestinal bleed, bowel obstruction, appendicitis) where the best treatment option was uncertain and asked them to: (1) judge the risks (probability of serious complications) and benefits (probability of recovery) for operative and nonoperative management and (2) decide whether or not they would recommend an operation. Across all clinical vignettes, surgeons varied markedly in both their assessments of the risks and benefits of operative and nonoperative management (narrowest range 4%-100% for all four predictions across vignettes) and in their decisions to operate (49%-85%). Surgeons were less likely to operate as their perceptions of operative risk increased [absolute difference (AD) = -29.6% from 1.0 standard deviation below to 1.0 standard deviation above mean (95% confidence interval, CI: -31.6, -23.8)] and their perceptions of nonoperative benefit increased [AD = -32.6% (95% CI: -32.8,--28.9)]. Surgeons were more likely to operate as their perceptions of operative benefit increased [AD = 18.7% (95% CI: 12.6, 21.5)] and their perceptions of nonoperative risk increased [AD = 32.7% (95% CI: 28.7, 34.0)]. Differences in risk/benefit perceptions explained 39% of the observed variation in decisions to operate across the four vignettes. Given the same clinical scenarios, surgeons' perceptions of treatment risks and benefits vary and are highly predictive of their decisions to operate.

After the Fukushima nuclear power plant accident, numerous evacuees reported poor mental health status and high-risk perceptions of the health effects of radiation. However, the temporal associations between these variables have not yet been examined. Using data from the Fukushima Health Survey, we examined changes in risk perception of the health effects of radiation over time and assessed the effects of mental health on such changes using logistic regression analysis. Risk perception for delayed effect pertains a brief on health effect in later life (delayed effect), whereas that of genetic effect pertains a brief on health effect of future children and grandchildren (genetic effect). We found that many participants showed consistently high or low-risk perceptions over all three study years (2011⁻2013) (for delayed effect: 59% and 41% of participants were in the low and high-risk perception groups, respectively; for genetic effect: 47% and 53%, respectively). Stronger traumatic reactions (≥50 on the PTSD Checklist⁻Specific) significantly affected the odds of being in the high-risk perception group for the delayed and genetic effects, with the associations being strongest soon after the disaster: The adjusted ORs (95%CIs) were 2.05 (1.82⁻2.31), 1.86 (1.61⁻2.15), and 1.88 (1.62⁻2.17) for the delayed effect in 2011, 2012, and 2013, respectively, and 2.18 (1.92⁻2.48), 2.05 (1.75⁻2.40), and 1.82 (1.55⁻2.15) for the genetic effect. As initial mental health status had the strongest impact on later risk perceptions of radiation, it should be considered in early response and communication efforts.

Stakeholder engagement is a vital sustainable remediation practice for obtaining useful feedback and identifying societal needs. Evaluating and integrating risk perception of stakeholders into remediation and outreach efforts allows for greater insight, increases the likelihood of success and ultimately, benefits the community by protecting its members from environmental hazards. In this study, we identified risk perception factors that influenced residents' level of concern for mitigating their exposure to elevated concentrations of lead in household paint and historic fill material. Risk perception factors were assessed by an in-person survey conducted in public green spaces. The analysis of survey participants' responses indicated that their perception of risk to exposed lead was mostly influenced by the presence of hazardous materials in close proximity to their residence, the ability to address pollution, and awareness, interest, and individual accountability in mitigating environmental risks. Responses also revealed that residents considered risk of lead and soil pollution as less menacing than the presence of more immediate and perceptible risks posed by factors such as air and water pollution. In addition, the community seemed to exhibit "optimism bias" and did not identify itself at high risk to susceptible and immediate hazards, including lead exposure. This lack of concern over lead exposure created a significant obstacle to community participation in state-led education and outreach programs. By integrating risk perception analysis and increasing stakeholder engagement, we can bring more attention to this issue, educate the public about the threat of lead pollution, and efficiently use financial resources to implement a more sustainable solution.

Risks of visiting snow destinations: an analysis of skiers' views.

PubMed

Carús, Luis

2010-03-01

Very little research exists regarding the risks of visiting snow destinations. This study attempts to bridge this gap through insights into skiers' perceptions of risk, of great relevance to snow industry stakeholders, by identifying factors that influence skiers. The research was conducted in the Spanish Pyrenees, using information gathered from adult members of two ski clubs that regularly visit this snow destination. Skiing risks, accommodation risks and public safety risks were found to have the most important bearing on visitors' risk perceptions. However, actual figures demonstrate that respondents had some difficulties in assessing the typicality of the risk items and tended to misjudge the true level of the risks.

Studies indicate that women fear breast cancer more than any other disease and that women's levels of breast cancer-specific intrusions are related to their perceived risk of breast cancer. Here, we explore possible biological consequences of higher breast cancer risk perceptions and intrusions in healthy women without personal or family histories of the disease. We hypothesized that women with higher perceived risk would have more intrusions about breast cancer, which would constitute a background stressor sufficient to increase hypothalamus-pituitary-adrenal axis (HPA) responsivity to daily stress. HPA responses to an ordinary life stressor (work) were assessed in 141 employed women (age = 37.2+/-9.2) without personal or family histories of breast cancer. Urinary cortisol excretion rates were assessed with timed sample collections at work, home, and during sleep. Repeated measures ANOVA revealed a significant Group by Time interaction with higher work cortisol levels in women with breast cancer-specific intrusions compared to women without intrusions (p < 0.02). Regression analyses revealed a significant association between risk perceptions and intrusions (p < 0.001). Regression analysis with intrusions and risk perceptions predicting work cortisol indicated a significant contribution of intrusions (p < 0.04), but not risk perceptions (p = 0.53). Overestimation of breast cancer risk is associated with higher levels of breast cancer-specific intrusions that can result in increased cortisol responsivity to daily stressors. This heightened responsivity could have long-term negative health implications.

Background Previous studies from western countries demonstrated the effectiveness of Teratology Information Service (TIS) counselling in reducing the teratogenic risk perception of pregnant women. Objective To assess whether TIS counselling would be effective in reducing the teratogenic risk perception of the Turkish pregnant women. Setting A TIS (Terafar) operating in a university hospital in Turkey. Methods A cross-sectional survey study. Pregnant women with non-teratogenic medication exposures were asked to assign scores on visual analogue scales (VAS) in response to the questions aiming to measure their teratogenic risk perception. The mean score before and after counselling were compared and the associations with maternal socio-demographic characteristics were analysed using SPSS (Version 20.0). Main outcome measures The differences in the mean scores of the perception regarding the baseline risk of pregnancy, own teratogenic risk and the likelihood of termination of pregnancy before and after counselling and their possible associations with maternal socio-demographic characteristics. Results 102 pregnant women participated in the study. The counselling significantly reduced the mean own teratogenic risk perception score and the mean score for the likelihood of termination of pregnancy whereas the mean baseline risk perception score was not significantly changed. Pregnancy week <8 and the exposed number of active ingredients <3 were significantly associated with the difference in the mean score for the likelihood of termination of pregnancy. Conclusions TIS counselling lowers the teratogenic risk perception of Turkish pregnant women and increases their likelihood to continue the pregnancy as it does in the western countries.

Inundations and landslides are widespread phenomena in Italy, where they cause severe damage and pose a threat to the population. Little is known on the perception of the population of landslides and floods. This is surprising, as an accurate perception is important for the successful implementation of many risk reduction or adaptation strategies. In an attempt to fill this gap, we have conducted two national surveys to measure the perception of landslide and flood risk of the population of Italy. The surveys were executed in 2012 and 2013, performing for each survey approximately 3100 computer assisted telephone interviews. The samples of the interviewees were statistically representative for a national scale quantitative assessment. The interviewees were asked questions designed to obtain information on their: (i) perception of natural, environmental, and technological risks, (ii) direct experience or general knowledge on the occurrence of landslides and floods in their municipality, (iii) perception of the possible threat posed by landslides and floods to their safety, (iv) general knowledge on the number of victims caused by landslides or floods, and on (v) the factors that they considered important to control landslide and flood risks in Italy. The surveys revealed that the population of Italy fears technological risks more than natural risks. Of the natural risks, earthquakes were considered more dangerous than floods, landslides, and volcanic eruptions. Examination of the temporal and geographical distribution of the responses revealed that the occurrence of recent damaging events influenced risk perception locally, and that the perception persisted longer for earthquakes and decreased more rapidly for landslides and floods. We justify the differentiation with the diverse consequences of the risks. The interviewees considered inappropriate land management the main cause of landslide and flood risk, followed by illegal construction, abandonment of the territory, and climate change. Comparison of the risk perception with actual measures of landslide and flood risk, including the number of fatal events, the number of fatalities, and the mortality rates, revealed that in most of the Italian regions the perception of the threat did not match the long-term risk posed by landslides and floods to the population. This outcome points to the need to fostering the understanding of the population of landslide and flood hazards and risks in Italy.

Using mental mapping to unpack perceived cycling risk.

Cycling is the most energy-efficient mode of transport and can bring extensive environmental, social and economic benefits. Research has highlighted negative perceptions of safety as a major barrier to the growth of cycling. Understanding these perceptions through the application of novel place-sensitive methodological tools such as mental mapping could inform measures to increase cyclist numbers and consequently improve cyclist safety. Key steps to achieving this include: (a) the design of infrastructure to reduce actual risks and (b) targeted work on improving safety perceptions among current and future cyclists. This study combines mental mapping, a stated-preference survey and a transport infrastructure inventory to unpack perceptions of cycling risk and to reveal both overlaps and discrepancies between perceived and actual characteristics of the physical environment. Participants translate mentally mapped cycle routes onto hard-copy base-maps, colour-coding road sections according to risk, while a transport infrastructure inventory captures the objective cycling environment. These qualitative and quantitative data are matched using Geographic Information Systems and exported to statistical analysis software to model the individual and (infra)structural determinants of perceived cycling risk. This method was applied to cycling conditions in Galway City (Ireland). Participants' (n=104) mental maps delivered data-rich perceived safety observations (n=484) and initial comparison with locations of cycling collisions suggests some alignment between perception and reality, particularly relating to danger at roundabouts. Attributing individual and (infra)structural characteristics to each observation, a Generalised Linear Mixed Model statistical analysis identified segregated infrastructure, road width, the number of vehicles as well as gender and cycling experience as significant, and interactions were found between individual and infrastructural variables. The paper concludes that mental mapping is a highly useful tool for assessing perceptions of cycling risk with a strong visual aspect and significant potential for public participation. This distinguishes it from more traditional cycling safety assessment tools that focus solely on the technical assessment of cycling infrastructure. Further development of online mapping tools is recommended as part of bicycle suitability measures to engage cyclists and the general public and to inform 'soft' and 'hard' cycling policy responses.

Background Breast cancer risk assessment including genetic testing can be used to classify people into different risk groups with screening and preventive interventions tailored to the needs of each group, yet the implementation of risk-stratified breast cancer prevention in primary care settings is complex. Objective To address barriers to breast cancer risk assessment, risk communication, and prevention strategies in primary care settings, we developed a Web-based decision aid, RealRisks, that aims to improve preference-based decision-making for breast cancer prevention, particularly in low-numerate women. Methods RealRisks incorporates experience-based dynamic interfaces to communicate risk aimed at reducing inaccurate risk perceptions, with modules on breast cancer risk, genetic testing, and chemoprevention that are tailored. To begin, participants learn about risk by interacting with two games of experience-based risk interfaces, demonstrating average 5-year and lifetime breast cancer risk. We conducted four focus groups in English-speaking women (age ≥18 years), a questionnaire completed before and after interacting with the decision aid, and a semistructured group discussion. We employed a mixed-methods approach to assess accuracy of perceived breast cancer risk and acceptability of RealRisks. The qualitative analysis of the semistructured discussions assessed understanding of risk, risk models, and risk appropriate prevention strategies. Results Among 34 participants, mean age was 53.4 years, 62% (21/34) were Hispanic, and 41% (14/34) demonstrated low numeracy. According to the Gail breast cancer risk assessment tool (BCRAT), the mean 5-year and lifetime breast cancer risk were 1.11% (SD 0.77) and 7.46% (SD 2.87), respectively. After interacting with RealRisks, the difference in perceived and estimated breast cancer risk according to BCRAT improved for 5-year risk (P=.008). In the qualitative analysis, we identified potential barriers to adopting risk-appropriate breast cancer prevention strategies, including uncertainty about breast cancer risk and risk models, distrust toward the health care system, and perception that risk assessment to pre-screen women for eligibility for genetic testing may be viewed as rationing access to care. Conclusions In a multi-ethnic population, we demonstrated a significant improvement in accuracy of perceived breast cancer risk after exposure to RealRisks. However, we identified potential barriers that suggest that accurate risk perceptions will not suffice as the sole basis to support informed decision making and the acceptance of risk-appropriate prevention strategies. Findings will inform the iterative design of the RealRisks decision aid. PMID:26175193

Acceptability of Health Care-Related Risks: A Literature Review.

Risk management aims at reducing risks associated with hospital care to an acceptable level, both in their frequency and their impact on health. The social acceptability of risk on the part of the general population and of the health-care professionals, faced with regular information about adverse events, is undoubtedly evolving rapidly.In contrast to risk acceptability, the concept of risk perception is of limited interest to risk managers because it does not inform on the behaviors and actions resulting from these perceptions. The aim of this work was to define the concept of social acceptability of risk through an in-depth examination of a wide-ranging and multidisciplinary literature. A 1990-2010 English and French literature review was carried out in medical, epidemiological, and human and social sciences online databases, gray literature, and books. Of the 5931 references retrieved, 203 met the inclusion criteria. We identified contributions from 5 major research fields: economic, sociocognitive, psychometric, sociological/anthropological, and interactionist. When assessing risks, individuals use a variety of psychological and social processes that include their perception not only of a given risk but also of their own personal and social resources. This global perception has a direct impact on the responses and actual behavior of individuals and groups, enabling them to cope with the risk and/or manage it. Social acceptability includes perceptions related to risks and the stated intentions of individual behavior. This concept may therefore be relevant for defining local and national patient safety priorities.

A Qualitative Comparison of Susceptibility and Behavior in Recreational and Occupational Risk Environments: Implications for Promoting Health and Safety.

Although internal factors that influence risk are frequently studied to understand human behavior, external factors, including social, cultural, and institutional factors, should be better utilized to inform ways to efficiently target, tailor, and promote safety messaging to at-risk populations. Semi-structured interviews obtained data from 37 motorcyclists and 18 mineworkers about their risk perceptions and behaviors within their respective dynamic environments. A comparative thematic analysis revealed information about external factors that influence risk perceptions and behaviors. Results support the importance of qualitative approaches for assessing and targeting individuals' risk perceptions and behaviors. In addition, segmenting at-risk subgroups within target populations and tailoring messages for these at-risk groups is critical for safety behavior modification. Practitioners should utilize strategic, culture-centric risk communication that takes into account external factors when determining when, who, and what to communicate via health promotion activities to more accurately disseminate valid, empathetic, and engaging communication with a higher level of fidelity.

Adolescence is an important time for the detection of health risk behaviors and factors with subsequent counseling and intervention. Limited research has examined adolescent perceptions of comprehensive health risk assessments (HRAs) and counseling with an assessment of gender differences. Participants were identified using Florida's Medicaid and State Children's Health Insurance Program databases. A total of 35 low-income, racially/ethnically diverse adolescents (ages 14-18 years) participated in eight focus groups stratified by gender. Adolescents completed an internet-based, tablet-administered, comprehensive HRA and then participated in a semi-structured interview. Discussions were recorded, transcribed, and analyzed using a multi-step, team-based approach applying grounded theory to determine major themes. Male adolescents desired less parental involvement, had less understanding of the protections of clinical confidentiality and the need for comprehensive HRA, and placed greater emphasis on the importance of professional appearance. In contrast, more females valued face-to-face interactions and stressed the importance of concern from the health risk assessor. Overall, adolescents placed importance on their relationship with the health risk assessor, and on valuing trust, confidentiality, and nonjudgmental care. Adolescents preferred to complete HRAs in clinical, private, and professional settings, and reported that tablet technology supported their confidentially in completing the HRA. Furthermore, they stressed the importance of autonomy and learning about the health risk outcomes for risk reduction. Gender differences exist in adolescent perceptions of comprehensive HRAs. Adolescent perceptions of HRAs support their use in confidential primary care settings using modalities that emphasize nonjudgmental, private care, and the use of communication techniques that respect adolescents' autonomy to change health risks.

Create a Spanish-language version of the Risk Perception Survey for Developing Diabetes (RPS-DD) and assess psychometric properties. The Spanish-language version was created through translation, harmonization, and presentation to the tool's original author. It was field tested in a foreignborn Latino sample and properties evaluated in principal components analysis. Personal Control, Optimistic Bias, and Worry multi-item Likert subscale responses did not cluster together. A clean solution was obtained after removing two Personal Control subscale items. Neither the Personal Disease Risk scale nor the Environmental Health Risk scale responses loaded onto single factors. Reliabilities ranged from .54 to .88. Test of knowledge performance varied by item. This study contributes to evidence of validation of a Spanish-language RPS-DD in foreign-born Latinos.

Family health history (FHH) in the context of risk assessment has been shown to positively impact risk perception and behavior change. The added value of genetic risk testing is less certain. The aim of this study was to determine the impact of Type 2 Diabetes (T2D) FHH and genetic risk counseling on behavior and its cognitive precursors. Subjects were non-diabetic patients randomized to counseling that included FHH +/- T2D genetic testing. Measurements included weight, BMI, fasting glucose at baseline and 12 months and behavioral and cognitive precursor (T2D risk perception and control over disease development) surveys at baseline, 3, and 12 months. 391 subjects enrolled of which 312 completed the study. Behavioral and clinical outcomes did not differ across FHH or genetic risk but cognitive precursors did. Higher FHH risk was associated with a stronger perceived T2D risk (p Kendall  < 0.001) and with a perception of "serious" risk (p Kendall  < 0.001). Genetic risk did not influence risk perception, but was correlated with an increase in perception of "serious" risk for moderate (p Kendall  = 0.04) and average FHH risk subjects (p Kendall  = 0.01), though not for the high FHH risk group. Perceived control over T2D risk was high and not affected by FHH or genetic risk. FHH appears to have a strong impact on cognitive precursors of behavior change, suggesting it could be leveraged to enhance risk counseling, particularly when lifestyle change is desirable. Genetic risk was able to alter perceptions about the seriousness of T2D risk in those with moderate and average FHH risk, suggesting that FHH could be used to selectively identify individuals who may benefit from genetic risk testing.

Mining-contaminated sites and the affected communities at risk are important issues on the agenda of both researchers and policy makers, particularly in the former communist block countries in Eastern Europe. Integrated analyses and expert based assessments concerning mining affected areas are important in providing solid policy guidelines for environmental and social risk management and mitigation. Based on a survey for 103 households conducted in a former mining site in the Certej Catchment of the Apuseni Mountains, western Romania, this study assesses local communities’ perceptions on the quality of water in their living area. Logistic regression was used to examine peoples’ perception on the quality of the main river water and of the drinking water based on several predictors relating to social and economic conditions. The results from the perception analysis were then compared with the measurements of heavy metal contamination of the main river and drinking water undertaken in the same study area. The findings indicate that perception and measurement results for the water quality in the Certej Catchment are convergent, suggesting an obvious risk that mining activities pose on the surface water. However, the perception on drinking water quality was little predicted by the regression model and does not seem to be so much related to mining as to other explanatory factors, such as special mineralogy of rock and soils or improper water treatment infrastructure, facts suggested by the measurements of the contaminants. Discussion about the implications of these joint findings for risk mitigation policies completes this article.

Objective To describe parent perceptions of their child's hospital discharge and assess the relationship between these perceptions and hospital readmission. Design A prospective study of parents surveyed with questions adapted from the care transitions measure, an adult survey that assesses components of discharge care. Participant answers, scored on a 5-point Likert scale, were compared between children who did and did not experience a readmission using a Fisher's exact test and logistic regression that accounted for patient characteristics associated with increased readmission risk, including complex chronic condition and assistance with medical technology. Setting A tertiary-care children's hospital. Participants: A total of 348 parents surveyed following their child's hospital discharge between March and October 2010. Intervention None. Main Outcome Measure Unplanned readmission within 30 days of discharge. Results There were 28 children (8.1%) who experienced a readmission. Children had a lower readmission rate (4.4 vs. 11.3%, P = 0.004) and lower adjusted readmission likelihood [odds ratio 0.2 (95% confidence interval 0.1, 0.6)] when their parents strongly agreed (n = 206) with the statement, ‘I felt that my child was healthy enough to leave the hospital’ from the index admission. Parent perceptions relating to care management responsibilities, medications, written discharge plan, warning signs and symptoms to watch for and primary care follow-up were not associated with readmission risk in multivariate analysis. Conclusions Parent perception of their child's health at discharge was associated with the risk of a subsequent, unplanned readmission. Addressing concerns with this perception prior to hospital discharge may help mitigate readmission risk in children. PMID:23962990

The Human Immunodeficiency Virus (HIV) pandemic is on the increase with the highest burden in sub-Saharan Africa. This descriptive cross-sectional study was carried out in 2008 to assess the knowledge, self-perception of risk of contracting HIV infection and risky sexual practices among patients attending some out-patient clinics at the University Teaching Hospital, Ado-Ekiti, Ekiti State, Nigeria. The knowledge on the modes of transmission and methods of prevention of HIV was high. Although, 53.0% of the study participants perceived themselves not to be at risk of contracting HIV infection, 80.6% were engaged in risky sexual practices within a year preceding the study. Significantly more participants with multiple sexual partners, past and present history of Sexually Transmitted Infections (STI) perceived themselves not to be at risk (P= 0.001, 0.008 and 0.001 respectively). Effective strategies must therefore be developed, to enhance risk-perception since poor risk-perception is known to mitigate behavioral change.

Engineered nanoscale materials (ENMs) present a difficult challenge for risk assessors and regulators. Continuing uncertainty about the potential risks of ENMs means that expert opinion will play an important role in the design of policies to minimize harmful implications while supporting innovation. This research aims to shed light on the views of ‘nano experts’ to understand which nanomaterials or applications are regarded as more risky than others, to characterize the differences in risk perceptions between expert groups, and to evaluate the factors that drive these perceptions. Our analysis draws from a web-survey (N = 404) of three groups of US and Canadian experts: nano-scientists and engineers, nano-environmental health and safety scientists, and regulatory scientists and decision-makers. Significant differences in risk perceptions were found across expert groups; differences found to be driven by underlying attitudes and perceptions characteristic of each group. Nano-scientists and engineers at the upstream end of the nanomaterial life cycle perceived the lowest levels of risk, while those who are responsible for assessing and regulating risks at the downstream end perceived the greatest risk. Perceived novelty of nanomaterial risks, differing preferences for regulation (i.e. the use of precaution versus voluntary or market-based approaches), and perceptions of the risk of technologies in general predicted variation in experts' judgments of nanotechnology risks. Our findings underscore the importance of involving a diverse selection of experts, particularly those with expertise at different stages along the nanomaterial lifecycle, during policy development.

Exploring the interactions between forecast accuracy, risk perception and perceived forecast reliability in reservoir operator's decision to use forecast

Advances in streamflow forecasts at different time scales offer a promise for proactive flood management and improved risk management. Despite the huge potential, previous studies have found that water resources managers are often not willing to incorporate streamflow forecasts information in decisions making, particularly in risky situations. While low accuracy of forecasts information is often cited as the main reason, some studies have found that implementation of streamflow forecasts sometimes is impeded by institutional obstacles and behavioral factors (e.g., risk perception). In fact, a seminal study by O'Connor et al. (2005) found that risk perception is the strongest determinant of forecast use while managers' perception about forecast reliability is not significant. In this study, we aim to address this issue again. However, instead of using survey data and regression analysis, we develop a theoretical framework to assess the user-perceived value of streamflow forecasts. The framework includes a novel behavioral component which incorporates both risk perception and perceived forecast reliability. The framework is then used in a hypothetical problem where reservoir operator should react to probabilistic flood forecasts with different reliabilities. The framework will allow us to explore the interactions among risk perception and perceived forecast reliability, and among the behavioral components and information accuracy. The findings will provide insights to improve the usability of flood forecasts information through better communication and education.

Purpose Perceptions about the pros and cons of genetic susceptibility testing are among the best predictors of test utilization. How actual testing changes such perceptions has yet to be examined. Methods In a clinical trial, first-degree relatives of patients with Alzheimer disease received genetic risk assessments for Alzheimer disease including APOE disclosure. Participants rated 11 possible benefits associated with genetic testing (pros) and 10 risks or limitations (cons) before genetic risk disclosure and again 12 months afterward. Results Pros were rated higher than cons at baseline (3.53 vs. 1.83, P < 0.001) and at 12 months after risk disclosure (3.33 vs. 1.88, P < 0.001). Ratings of pros decreased during the 12-month period (3.33 vs. 3.53, P < 0.001). Ratings of cons did not change (1.88 vs. 1.83, P = 0.199) except for a three-item discrimination subscale which increased (2.07 vs. 1.92, P = 0.012). Among specific pros and cons, three items related to prevention and treatment changed the most. Conclusion The process of APOE genetic risk assessment for Alzheimer disease sensitizes some to its limitations and the risks of discrimination; however, 1-year after disclosure, test recipients still consider the pros to strongly outweigh the cons.

Current National Health Service cervical screening information does not explain that the cause of cervical cancer is a sexually transmitted infection (human papillomavirus (HPV)). This study aimed to consider the impact that providing this information, in addition to risk factor information, might have on women's perceived risk of cervical cancer. Female students aged 18-24 years (n=606) completed a web-based survey and were randomised to receive (1) control information about cervical cancer; (2) details of the link between HPV and cervical cancer; (3) risk factor information or (4) details about the link with HPV + risk factor information. Risk perceptions for cervical cancer were assessed before and after reading the information. There was a significant difference in perceived risk of cervical cancer between the four groups following information exposure (p=0.002). Compared with the control group, risk perceptions were significantly lower among women given risk factor information but not among those informed about HPV. There were significant group by risk factor interactions for smoking status (p<0.001), age of first sex (p=0.018) and number of sexual partners (p<0.001). Risk perceptions were lower among women considered at low risk and given risk factor information, but there was no association between information group and perceived risk for high-risk women. Providing risk factor information appears to reduce cervical cancer risk perceptions, but learning about the aetiological role of HPV appears to have no impact on risk perceptions. Incorporating brief information about HPV as the cause of cervical cancer should be in addition to, rather than in place of, risk factor information.

Familiarity with a given population's perception of natural hazards and the threats they present is vital for the development of effective education prior to and emergency management response after a natural event. While much work has been done in other active tectonic regions, perception of natural hazards and risk among Pacific Northwest (PNW) residents is poorly constrained. The objective of this work is to assess the current perception of earthquake and volcanic hazards and risk in the PNW, and to better understand the factors which drive the public's behavior concerning preparedness and response. We developed a survey to assess the knowledge of natural hazards common to the region, their perception of risk concerning these hazards, and their level of preparedness should a natural hazard occur. The survey was distributed to University of Washington students and employees via an internet link as part of a class project in 'Living with Volcanoes' (ESS 106) in March of 2012, which returned more than 900 responses. The UW student population was chosen as our first "population" to assess because of their uniqueness as a large, semi-transient population (typical residence of less than 5 years). Only 50% of participants correctly reported their proximity to an active volcano, indicating either lack of knowledge of active volcanoes in the region or poor spatial awareness. When asked which area were most at risk to lahars, respondents indicated that all areas close to the hazard source, including topographically elevated regions, were at a higher risk than more distal and low-lying localities that are also at high risk, indicating a lack of knowledge concerning the topographic dependency of this hazard. Participants perceived themselves to be able to cope better with an earthquake than a volcanic event. This perception may be due to lack of knowledge of volcanic hazards and their extent or due to a false sense of security concerning earthquakes fostered by regular earthquake drills and long periods of quiescence between large earthquake events. 60% of respondents had participated in earthquake drills; however, less than 45% provided the correct response when asked what they would do if an earthquake were to occur. In summary, knowledge of natural hazards and proximity to hazard sources was found to be low or inaccurate, which corresponds to a low perception of risk. Awareness of evacuation routes, emergency response or coping protocol for natural hazards was also found to be low, suggesting this large, semi-transient population lacks the understanding of proper preparation and response to a natural hazard. These results indicate the need for better education concerning the risks of natural hazards in this region and the steps for better preparedness.

Policy makers and regulators are constantly required to make decisions despite the existence of substantial uncertainty regarding the outcomes of their proposed decisions. Understanding stakeholder views is an essential part of addressing this uncertainty, which provides insight into the possible social reactions and tolerance of unpredictable risks. In the field of nanotechnology, large uncertainties exist regarding the real and perceived risks this technology may have on society. Better evidence is needed to confront this issue. We undertook a computer assisted telephone interviewing (CATI) survey of the Australian public and a parallel survey of those involved in nanotechnology from the academic, business and government sectors. Analysis included comparisons of proportions and logistic regression techniques. We explored perceptions of nanotechnology risks both to health and in a range of products. We examined views on four trust actors. The general public's perception of risk was significantly higher than that expressed by other stakeholders. The public bestows less trust in certain trust actors than do academics or government officers, giving its greatest trust to scientists. Higher levels of public trust were generally associated with lower perceptions of risk. Nanotechnology in food and cosmetics/sunscreens were considered riskier applications irrespective of stakeholder, while familiarity with nanotechnology was associated with a reduced risk perception. Policy makers should consider the disparities in risk and trust perceptions between the public and influential stakeholders, placing greater emphasis on risk communication and the uncertainties of risk assessment in these areas of higher concern. Scientists being the highest trusted group are well placed to communicate the risks of nanotechnologies to the public.

Youths, aged 15-24 years, comprise a large fragment of the total population in Thailand, and unsafe sexual behaviours are increasing, nowadays, among young people. The study was conducted to explore the characteristics of youths and other conducive, facilitating and reinforcing factors associated with risk perception of sexually transmitted infections (STIs) among the study population. Data employed in this study were derived from the site of the Kanchanaburi Demographic Surveillance System of Thailand 2004 using a stratified systemic design. The study population was mainly young current condom-users aged 15-24 years, and cross-sectional analysis was done on this populace. The findings revealed that youths who fell into the single (unmarried) category having temporary partners were more likely to perceive the risks associated with STIs in relation to using condom. A greater proportion of unmarried youths was engaged in sexual activity before the age of 20 years and that condom-use was also inconsistent. Youths having temporary partners were more likely to perceive risk and reason for using a condom than when with their regular partner. Education played a significant role in risk perception of STIs. Risk perception was increasing with the increasing level of education. Other conducive and facilitating factors, such as household wealth, living in urban or semi-urban areas, and access to mass media such as television, also had a positive influence on risk perception. The odds ratio showed that condom-users who had indulgence in liquor were less likely to perceive the risk of STIs. Overall, socioeconomic status had a great influence on risk perception of STIs. Finally, youths exhibiting high-risk sexual behaviour need realistic risk assessments and positive ways of incorporating condom into their sexual lives.

Asbestos is known to be an independent risk factor for lung and pleural cancers. However, to date, little attention has been paid to the psychological effects of asbestos exposure among exposed subjects. The objectives of this study were to estimate the prevalence of anxious and depressive symptoms among >2000 French participants of the Asbestos-Related Diseases Cohort (ARDCO), 6 years after their inclusion, to identify the risk factors associated with those anxious and depressive symptoms and to evaluate the impact of the asbestos-risk perception. The ARDCO was constituted in four regions of France between October 2003 and December 2005, by including former asbestos workers. Between 2011 and 2012, participants of the ARDCO program were invited to undergo another chest CT scan 6 years after the previous scan. Participants were asked to complete questionnaires including asbestos exposure assessment, Hospital Anxiety and Depression Scale (HADS), asbestos-risk perception and self-perception of asbestos-related diseases. Among the 2225 participants, 2210 fully completed questionnaires were collected and analyzed. The prevalence of symptoms of probable anxiety and probable depression was 19.7% and 9.9%, respectively. The risk of anxious and depressive symptoms was independently associated with self-perception of the intensity of asbestos exposure, asbestos-risk perception and self-perception of asbestos-related diseases. The results obtained in this large study confirm that previously asbestos-exposed subjects are likely to develop anxious and depressive symptoms. Finally, implications related to the prevention of anxiety and depression among asbestos-exposed workers is discussed. © The Author 2016.

Heat waves are considered a health risk and they are likely to increase in frequency, intensity and duration as a consequence of climate change. The effects of heat waves on human health could be reduced if individuals recognise the risks and adopt healthy behaviours during a heat wave. The purpose of this study was to determine the predictors of risk perception using a heat wave scenario and identify the constructs of the health belief model that could predict adaptive behaviours during a heat wave. A cross-sectional study was conducted during the summer of 2012 among a sample of persons aged between 30 to 69 years in Adelaide. Participants’ perceptions were assessed using the health belief model as a conceptual frame. Their knowledge about heat waves and adaptive behaviours during heat waves was also assessed. Logistic regression analyses were performed to determine the predictors of risk perception to a heat wave scenario and adaptive behaviours during a heat wave. Of the 267 participants, about half (50.9%) had a high risk perception to heat waves while 82.8% had good adaptive behaviours during a heat wave. Multivariate models found that age was a significant predictor of risk perception. In addition, participants who were married (OR = 0.21; 95% CI, 0.07–0.62), who earned a gross annual household income of ≥$60,000 (OR = 0.41; 95% CI, 0.17–0.94) and without a fan (OR = 0.29; 95% CI, 0.11–0.79) were less likely to have a high risk perception to heat waves. Those who were living with others (OR = 2.87; 95% CI, 1.19–6.90) were more likely to have a high risk perception to heat waves. On the other hand, participants with a high perceived benefit (OR = 2.14; 95% CI, 1.00–4.58), a high “cues to action” (OR = 3.71; 95% CI, 1.63–8.43), who had additional training or education after high school (OR = 2.65; 95% CI, 1.25–5.58) and who earned a gross annual household income of ≥$60,000 (OR = 2.66; 95% CI, 1.07–6.56) were more likely to have good adaptive behaviours during a heat wave. The health belief model could be useful to guide the design and implementation of interventions to promote adaptive behaviours during heat waves. PMID:23759952

Although food allergy is known to be associated with increased disease burden, factors that shape parents' perception of their child's risk of future severe or fatal anaphylaxis are poorly understood. This study aimed to evaluate factors associated with parents' perceived risk of food-induced anaphylaxis. A questionnaire-based survey of 202 parents was conducted in a single specialist center outpatient clinic that treats children with food allergies. Parents' perceived risk of their child experiencing further food-induced anaphylaxis was assessed by using a validated food allergy independent measure. Demographic data as well as parents' anxiety and depression scores were assessed by using the Hospital Anxiety and Depression score. Nineteen percent of parents believed that their child had a moderate-to-high chance of dying from food-induced anaphylaxis. A lack of a university education, higher anxiety score, and, particularly, possession of an epinephrine autoinjector (relative risk 9.9 [95% confidence interval, 3.3-30]) were key factors associated with heightened risk perception. Caring for a child with multiple food allergies was the main factor associated with parents feeling less able to manage future reactions (relative risk 9.5 [95% confidence interval, 1.7-53]). Parents' risk perception of fatal anaphylaxis correlated with anxiety and mood scores. Parents' education, affect, and possession of an epinephrine autoinjector were associated with a heightened perceived risk of future anaphylaxis. Clinicians should consider not only the child's needs but should also provide counseling for parents, particularly those who possess autoinjectors. Parents of children with multiple food allergies may need additional education and training to help them cope with future reactions.

Agents of opportunity (AO) are potentially harmful biological, chemical, radiological, and pharmaceutical substances commonly used for health care delivery and research. AOs are present in all academic medical centers (AMC), creating vulnerability in the health care sector; AO attributes and dissemination methods likely predict risk; and AMCs are inadequately secured against a purposeful AO dissemination, with limited budgets and competing priorities. We explored health care workers' perceptions of AMC security and the impact of those perceptions on AO risk. Qualitative methods (survey, interviews, and workshops) were used to collect opinions from staff working in a medical school and 4 AMC-affiliated hospitals concerning AOs and the risk to hospital infrastructure associated with their uncontrolled presence. Secondary to this goal, staff perception concerning security, or opinions about security behaviors of others, were extracted, analyzed, and grouped into themes. We provide a framework for depicting the interaction of staff behavior and access control engineering, including the tendency of staff to "defeat" inconvenient access controls. In addition, 8 security themes emerged: staff security behavior is a significant source of AO risk; the wide range of opinions about "open" front-door policies among AMC staff illustrates a disparity of perceptions about the need for security; interviewees expressed profound skepticism concerning the effectiveness of front-door access controls; an AO risk assessment requires reconsideration of the security levels historically assigned to areas such as the loading dock and central distribution sites, where many AOs are delivered and may remain unattended for substantial periods of time; researchers' view of AMC security is influenced by the ongoing debate within the scientific community about the wisdom of engaging in bioterrorism research; there was no agreement about which areas of the AMC should be subject to stronger access controls; security personnel play dual roles of security and customer service, creating the negative perception that neither role is done well; and budget was described as an important factor in explaining the state of security controls. We determined that AMCs seeking to reduce AO risk should assess their institutionally unique AO risks, understand staff security perceptions, and install access controls that are responsive to the staff's tendency to defeat them. The development of AO attribute fact sheets is desirable for AO risk assessment; new funding and administrative or legislative tools to improve AMC security are required; and security practices and methods that are convenient and effective should be engineered.

Phthalates have been detected in various types of retail foods. Consumers' exposure to phthalates is common. Consumers are concerned about chemicals in food. Our aim was to investigate the relationships between consumers' exposure to phthalates through food, consumers' interest in a natural and healthy diet, risk perception of food chemicals, and consumers' diet patterns. We collected data through a mail survey in the adult Swiss-German population (N = 1,200). We modeled exposure to di(2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), benzyl butyl phthalate (BBP), and diethyl phthalate (DEP) based on a food frequency questionnaire and phthalate concentrations reported from food surveys. Using rating scales, we assessed risk perceptions of chemicals in food and interest in a natural and healthy diet. Higher risk perceptions and higher natural and healthy diet interest were associated with higher daily doses of DEHP, BBP, and DEP. No health risk from phthalates in food was identified for the vast majority of the population. Four consumers' diet clusters were discerned, with differences in phthalate exposure, risk perceptions, and interest in a natural and healthy diet. This study shows that even those consumers who express strong interest in natural food and low acceptance of food chemicals, and who try to make respective food choices, are exposed to contaminants such as phthalates.

Risk perceptions of STIs/HIV and sexual risk behaviours among sexually experienced adolescents in the Northern part of Lao PDR

PubMed Central

2013-01-01

Background Young people in Laos are more vulnerable to STIs/HIV due to their sexual risk behaviours, low perceptions of risk and their socio-cultural environments. Perceived risk of contracting STIs/HIV is crucial for the assessment of their risk regarding their actual sexual risk behaviors. Thus, the objective of this paper is to explore perceptions of risk related to STIs/HIV and identify factors associated with this perceived risk among adolescents. Methods This was a cross sectional study of sexually experienced adolescents aged 14 to 19 years old in the Luangnamtha province. The multistage sampling techniques were used for selecting 1008 adolescents aged 14-19 years old. Of these, 483 respondents reported having had sexual experience was selected for analysis. Univariate and Logistic regression were performed. Result Six per cent of respondents reported ever having had anal sex. Slightly less than two thirds initiated their first sexual intercourse before age 15. Two thirds of the sexually experienced males reported two or more sexual partners during their lifetime with the mean 3.1 + 3.65 while only twelve per cent of girls reported this cumulative number of partners. Slightly more than half (57.6%) regarded themselves to have no risk at all with 17.2 per cent considered themselves to have low risk. Respondents had poor knowledge on STIs/HIV. Factors associated with risk perception of getting STIs were: being male, high level of knowledge about STIs and having had symptoms of STIs in last six months. Perceived risk of getting HIV was significantly associated with being male, having more knowledge about STIs and HIV. Conclusion Adolescents in this study engaged in sexual risk behaviours, but they have low perception of risk getting STI/HIV. Socio-demographic factors, knowledge of STIs/HIV, and the level of exposure to STIs were the main determinants of the risk perception of STIs/HIV. Our finding supports the need to target adolescents in Luangnamtha province for HIV prevention intervention by addressing inaccurate perception of risk and increasing their knowledge on STIs/HIV.

Bariatric surgery (BSx) produces clinically relevant weight loss that translates into improved quality of life, decreased mortality, and reduction in medical comorbidities, including cardiovascular (CV) risk. Little is known about patients' decision-making process to undergo BSx, but risk perception is known to influence medical decision-making. This study examined CV and BSx risk perception in obese subjects undergoing BSx (n = 268) versus those managed medically (MM) (n = 273). This retrospective population-based survey of subjects evaluated for BSx had 148 (55%) and 88 (32%) responders in the BSx and MM groups, respectively. Survey questions assessed risk perceptions and habits prior to weight loss intervention. CV risk was calculated using the Framingham Risk Score (FRS). At baseline, BSx subjects had a greater body mass index and greater prevalence of diabetes and depression. Follow-up mean weight loss was greater in the BSx group. BSx subjects perceived obesity as a greater risk to their overall health than the surgical risk. FRS declined in the BSx group (10 to 5%; p < 0.001) while there was no change in the MM group (8 to 8%; p = 0.54). Those without a measurable decrease in CV risk had a greater tendency to perceive the risk of BSx as greater than that of obesity. Obese subjects undergoing BSx are more likely than MM subjects to perceive obesity as a greater risk to their health than BSx. MM subjects generally underestimate their CV risk and overestimate the risk of BSx. Active discussion of CV risk using the FRS and the perception of risk associated with bariatric surgery can enhance patients' ability to make an informed decision regarding their management. © The European Society of Cardiology 2012 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Concussion is increasingly recognized as a risk of participation in contact and collision sports. There have been few examinations of athletes' perceptions of their susceptibility to concussion or concussion-related health consequences. We examine college football players' perceptions of their risk of sustaining a concussion and concussion-related health consequences in their future, whether these perceptions change over time, and how concussion history is related to perceived future risk of concussion and concussion-related health consequences. A survey was administered to National Collegiate Athletic Association Division I Football Championship Series athletes on 10 teams in 2013 and to nine of those teams in 2014. Athletes answered questions assessing their perceptions of concussion and potential concussion-related health consequences. Approximately 40% of athletes believed there was a strong possibility that they would sustain a concussion in the future, while approximately one-in-four thought a concussion would make them miss a few games. About one-in-10 athletes predicted dementia, Alzheimer's disease, or chronic traumatic encephalopathy would develop from concussions. These beliefs were stronger among athletes who had sustained previous concussions. Across the two years studied, athletes' perceptions of the risk of concussion and missing a few games because of concussion decreased significantly. Overall, a substantial proportion of college football players believe they will have long-term health consequences as a result of sustaining sport-related concussions. The true incidence and prevalence of many of these outcomes are unknown. Further research is needed to determine whether athletes have an accurate perception of the risks of these outcomes developing.

Prediction and perception of hazards in professional drivers: Does hazard perception skill differ between safe and less-safe fire-appliance drivers?

PubMed

Crundall, David; Kroll, Victoria

2018-05-18

Can hazard perception testing be useful for the emergency services? Previous research has found emergency response drivers' (ERDs) to perform better than controls, however these studies used clips of normal driving. In contrast, the current study filmed footage from a fire-appliance on blue-light training runs through Nottinghamshire, and endeavoured to discriminate between different groups of EDRs based on experience and collision risk. Thirty clips were selected to create two variants of the hazard perception test: a traditional push-button test requiring speeded-responses to hazards, and a prediction test that occludes at hazard onset and provides four possible outcomes for participants to choose between. Three groups of fire-appliance drivers (novices, low-risk experienced and high-risk experienced), and age-matched controls undertook both tests. The hazard perception test only discriminated between controls and all FA drivers, whereas the hazard prediction test was more sensitive, discriminating between high and low-risk experienced fire appliance drivers. Eye movement analyses suggest that the low-risk drivers were better at prioritising the hazardous precursors, leading to better predictive accuracy. These results pave the way for future assessment and training tools to supplement emergency response driver training, while supporting the growing literature that identifies hazard prediction as a more robust measure of driver safety than traditional hazard perception tests.

Many studies have explored the risk perception of frequent business travelers (FBT) toward malaria. However, less is known about their knowledge of other infectious diseases. This study aimed to identify knowledge gaps by determining the risk perception of FBT toward 11 infectious diseases. Our retrospective web-based survey assessed the accuracy of risk perception among a defined cohort of FBT for 11 infectious diseases. We used logistic regression and the chi-square test to determine the association of risk perception with source of travel advice, demographic variables, and features of trip preparation. Surveys were returned by 63% of the 608 self-registered FBT in Rijswijk, and only the 328 completed questionnaires that adhered to our inclusion criteria were used for analysis. The majority (71%) sought pre-travel health advice and used a company health source (83%). Participants seeking company travel health advice instead of external had significantly more accurate risk knowledge (p = 0.03), but more frequently overestimated typhoid risk (odds ratio = 2.03; 95% confidence interval = 1.23-3.34). While underestimation of disease risk was on average 23% more common than overestimation, HIV risk was overestimated by 75% of FBT. More accurate knowledge among FBT seeking company health advice demonstrates that access to in-company travel clinics can improve risk perception. However, there is an obvious need for risk knowledge improvement, given the overall underestimation of risk. The substantial overestimation of HIV risk is probably due to both public and in-company awareness efforts. Conversely, typhoid risk overestimation was statistically associated with seeking company health advice, and therefore specifically reflects the high focus on typhoid fever within Shell's travel clinic. This study serves as a reminder that a knowledge gap toward infectious diseases besides malaria still exists. Our article will explore the future requirements for more targeted education and research among FBT in companies worldwide. © 2012 International Society of Travel Medicine.

Aging in place is a preferred and cost-effective living option for older adults. Research indicates that technology can assist with this goal. Information on consumer preferences will help in technology development to assist older adults to age in place. The study aim was to explore the perceptions and preferences of older adults and their family members about a fall risk assessment system. Using a qualitative approach, this study examined the perceptions, attitudes, and preferences of 13 older adults and five family members about their experience living with the fall risk assessment system during five points in time. Themes emerged in relation to preferences and expectations about the technology and how it fits into daily routines. We were able to capture changes that occurred over time for older adult participants. Results indicated that there was acceptance of the technology as participants adapted to it. Two themes were present across the five points in time-safety and usefulness. Five stages of acceptance emerged from the data from preinstallation to 2 years postinstallation. Identified themes, stages of acceptance, and design and development considerations are discussed.

In a multi-site study of vaginal microbicide acceptability conducted with sexually active young women, quantitative assessments revealed significant differences in acceptability by site. Participants in Puerto Rico rated the gel more favourably than mainland US participants in terms of liking the gel and likelihood of future use. To explain these differences, we examined responses to qualitative behavioural assessments. Young women in the mainland USA associated gel leakage with uncomfortable sensations experienced during menstruation, while young women in Puerto Rico had positive associations of gel use with douching. These negative or positive associations affected assessments of the gel’s physical qualities. In addition, young women’s perceptions of primary partners’ support for microbicide use influenced sexual satisfaction with the gel and, ultimately, product acceptability. Finally, geographic HIV risk context contributed to heightened HIV risk perception, which influenced likelihood of future microbicide use, even for women in stated monogamous relationships. Future microbicide acceptability studies should take into account potential differences in acceptability by site such as HIV risk perception based on local HIV prevalence, popularity of vaginal hygiene products in a specific area, and male attitudes in different cultures concerning women’s use of HIV protection strategies.

Background Findings from inflammatory bowel disease (IBD) genome-wide association studies are being translated clinically into prognostic and diagnostic indicators of disease. Yet, patient perception and understanding of these tests and their applicability to providing risk information is unclear. The goal of this study was to determine, using hypothetical scenarios, whether patients with IBD perceive genetic testing to be useful for risk assessment, whether genetic test results impact perceived control, and whether low genetic literacy may be a barrier to patient understanding of these tests. Methods Two hundred fifty seven patients with IBD from the Johns Hopkins gastroenterology clinics were randomized to receive a vignette depicting either a genetic testing scenario or a standard blood testing scenario. Participants were asked questions about the vignette and responses were compared between groups. Results Perceptions of test utility for risk assessment were higher among participants responding to the genetic vignette (P < 0.001). There were no significant differences in perceptions of control over IBD after hypothetical testing between vignettes (P = 0.24). Participant responses were modified by genetic literacy, measured using a scale developed for this study. Participants randomized to the genetic vignette who scored higher on the genetic literacy scale perceived greater utility of testing for risk assessment (P = 0.008) and more control after testing (P = 0.02). Conclusions Patients with IBD perceive utility in genetic testing for providing information relevant to family members, and this appreciation is promoted by genetic literacy. Low genetic literacy among patients poses a potential threat to effective translation of genetic and genomic tests. PMID:24691112

Little is known regarding the risk perceptions and attitudes of laboratory animal care workers toward biologic safety. The purpose of this descriptive study was to assess the attitudes and perceptions of laboratory animal workers toward occupational and injury risk. Subscribers to the CompMed and TechLink listservs (n = 4808) were surveyed electronically, and 5.3% responded; data from 215 respondents were included in the final analysis. Primary variables of interest included AALAS certifications status, level of education, and responses to Likert-scale questions related to attitudes and perceptions of occupational risk and injury. Nonparametric (χ(2)) testing and measures of central tendency and dispersion were used to analyze and describe the data. According to 88.6% of respondents, biologic safety training is provided with information about zoonotic diseases of laboratory animals. Level of education was significantly related to perception of importance regarding wearing personal protective equipment. Participants indicated that appropriate support from coworkers and management staff is received, especially when performance and perception are hindered due to stress and fatigue. Laboratory animal staff are susceptible to injury and exposure to dangerous organisms and toxic substances. For this reason, to maximize safety, yearly biologic safety training should be provided, the importance of protective equipment adherence strengthened, and the culture of safety made a priority within the institution.

In recent years, the interest in health and safety in the workplace has increased. Agriculture is one of the human work activities with the highest risk indexes. Studies on risk perception of agricultural workers are often referred to as specific risk factors (especially pesticides), but the risk perception plays an important role in preventing every kind of accident and occupational disease. The aim of this research is to test a new method for understanding the relation between risk perception among farmers and the main risk factors to which they are exposed. A secondary aim is to investigate the influence of training in risk perception in agriculture. The data collection was realized using a questionnaire designed to investigate the risk perception; the questionnaire was given to a sample of 119 agricultural workers in central Italy. Through the use of the "principal components analysis" it was possible to highlight and verify the latent dimensions underlying the collected data in comparison with scales of attitudes. Results show that the highest percentage of strong negative attitude is among the people who have worked for more years, while farmers who have worked for fewer years have a marked positive attitude. The analysis of the questionnaires through the synthetic index method (Rizzi index) showed that agricultural workers involved, in particular the elderly workers, have a negative attitude towards safety; workers are hostile to safety measures if they have not attended special training courses.

The relationship between risk perception and risk avoidance is typically analyzed using self-reported measures. However, in domains such as driving or food handling, the validity of responses about usual behavior is threatened because people think about the situations in which they are self-aware, such as when they encounter a hazard. Indeed, researchers have often noted a divergence between what people say about their behavior and how they actually behave. Thus, in order to draw conclusions about risk perceptions and risk avoidance from survey data, it is important to identify particular cognitive elements, such as those measured by questions about risk and safety knowledge, risk perceptions, or information search behavior, which may be effective antecedents of self-reported safety behavior. It is also important to identify and correct for potential sources of bias that may exist in the data. The authors analyze the Food and Drug Administration's 1998 Food Safety Survey to determine whether there are consistent cognitive antecedents for three types of safe food practices: preparation, eating, and cooling of foods. An assessment of measurement biases shows that endogeneity of food choices affects reports of food preparation. In addition, response bias affects reports of cooling practices as evidenced by its relation to knowledge and information search, a pattern of cognitive effects unique to cooling practices. After correcting for these biases, results show that practice-specific risk perceptions are the primary cognitive antecedents of safe food behavior, which has implications for the design of effective education messages about food safety.

Adolescents’ risk perceptions on mobile phones and their base stations, their trust to authorities and incivility in using mobile phones: a cross-sectional survey on 2240 high school students in Izmir, Turkey

Background Use of mobile phones has rapidly risen among adolescents despite a lack of scientific certainty on their health risks. Risk perception is an important determinant of behavior, and studies on adolescents’ risk perceptions of mobile phones or base stations are very scarce. This study aims to evaluate high school students’ risk perceptions on mobile phones and base stations, their trust to authorities, their opinions regarding incivility while using mobile phones and to assess associated factors. Methods For this cross-sectional study, 2530 students were chosen with stratified cluster sampling among 20,493 high school students studying in Bornova district of Izmir, Turkey, among whom 2240 (88.5%) participated. Risk perceptions and opinions were questioned with a 5-point Likert scale for 24 statements grouped under four dimensions. The mean responses to the four dimensions were categorized as <3.5 (low) and ≥3.5 (high) and the determinants were analyzed with logistic regression. Results Mean risk perception scores for the mobile phone, base station, trust to authority and incivility dimensions were 3.69 ± 0.89, 4.34 ± 0.78, 3.77 ± 0.93, 3.16 ± 0.93 and the prevalence of high risk perception was 65.1%, 86.7%, 66.2%, 39.7%, respectively. In the mobile phone dimension; students attending industrial technical high school had lower risk perceptions while female students, lower mothers’ education groups and students not using mobile phones (OR = 2.82, 95% CI = 1.80-4.40) had higher risk perceptions. In the base station dimension girls had higher risk perceptions (OR = 1.68, 95% CI = 1.20-2.37). Girls and students attending industrial technical high school had significantly lower risk perception however 11-12th grade group perceived the risk higher (OR = 1.45 95% CI = 1.15-1.84) in the trust to authority dimension. For the incivility dimension, female students (OR = 1.44, 95% CI = 1.14-1.82), illiterate/only literate mothers (OR = 1.79, 95% CI = 1.04-2.75) and students not using mobile phones (OR = 2.50, 95% CI = 1.62-3.87) perceived higher risk. Conclusions Understanding the effects of these determinants might aid in developing more effective educational interventions to specific subgroups on this topic. As debates on the health consequences of electromagnetic fields continue, it would be cautious to approach this issue with a preventive perspective. Efforts should be made to equalize the varying level of knowledge and to ensure that students are informed accurately. PMID:23351724

Impact of smokeless tobacco packaging on perceptions and beliefs among youth, young adults, and adults in the U.S: findings from an internet-based cross-sectional survey

PubMed Central

2014-01-01

Background Research demonstrates that tobacco packaging elements (including health warning labels, descriptive characteristics, and corporate branding) are associated with knowledge of health risks and product appeal with cigarettes. Yet, little research has assessed this with smokeless tobacco (SLT) packaging. This study evaluates the association between three SLT packaging elements with knowledge of health risks and perceptions of novelty and appeal. Additionally, we assess how effects of these messages may differ across age groups, including youth (14-17 years), young adults (18-25 years), and older adults (26-65 years). Methods 1000 participants were administered a web-based survey in 2010 and shown three sets of SLT packs in random order, varied by descriptor (flavor descriptor vs. none), warning label format (graphic vs. text), and corporate branding (branded vs. plain packaging). Participants rated the packs compared with “no difference” on appeal, novelty, and risk perceptions associated with product use. Chi-square tests were used to test for significant differences in pack selections. Multinomial regression was employed to evaluate the association between effects of packaging elements and participant age. Results More respondents selected the pack with the graphic warning label as the pack to make them consider the health risks associated with SLT use, attract their attention, and be least attractive to a smoker. The product with the text warning label was the product someone their age would want to be seen using and would appeal to peers. The SLT pack with the flavor descriptor was not associated with health risks associated with product use. The pack with corporate branding was selected as more appealing, to attract attention, and one they would want to be seen using; the plain pack was less attractive to smokers. Youth and young adults were more likely to indicate that pack elements affected their perceptions of appeal and risk associated with SLT products. Conclusion These results suggest that SLT pack characteristics have a measurable effect on perceptions of health risk and product appeal. Future research should assess these findings in the context of harm reduction. Specifically, research is needed to determine whether pack elements on SLT products can effectively convey risk and harm. PMID:24433301

Researchers have previously reported that hazard proximity can influence risk perception among individuals exposed to potential hazards. Understanding this relationship among coastline communities at risk of flood events caused by storms and/or tsunamis, is important because hazard proximity, should be recognized when planning and implementing preparation and mitigation actions against these events. Yet, we are not aware of studies that have examined this relationship among coastline inhabitants facing the risk of a tsunami. Consequently, the aim of this study was to examine the relationship between hazard proximity and perceived risk from tsunamis among coastline inhabitants. Participants were 487 residents of the coastal city of Iquique, Chile. They completed a survey during the spring of 2013 that assessed their perceived risk from several natural and non-natural hazards. We found that hazard proximity maintains a negative relationship with the perception of tsunami risk among coastline inhabitants. While this result confirms the general trend obtained in previous studies, this one is conclusive and significant. In contradiction with previous findings, we found that participants from the highest socioeconomic status reported the highest levels of risk perception. This finding can be explained by the fact that most participants from the highest socioeconomic status live closer to the coastline areas, so their risk perception reflects the place where they live, that is in a tsunami inundation zone. Once again, hazard proximity proved to be a determinant factor of risk perception. Our findings have important implications for the development of plans and programs for tsunami preparedness and mitigation. These indicate that individuals do use environmental cues to evaluate their own risk and can potentially make correct choices when having or not to evacuate. Also suggest that preparedness should incorporate how hazard proximity is recognized by individuals and communities at risk.

Risk communication, especially to the general public and end users of plant protection products, is an important challenge. Currently, much of the risk communication the general public receives is via the popular press, and risk managers face the challenge of presenting their decisions and their scientific basis to the general public in an understandable way. Therefore, we decided to explore the obstacles in risk communication, as done by expert risk assessors and managers. Using the discourse analysis framework and readability tests, we studied perspectives of 3 stakeholder groups-regulators, industry representatives, and academics across Europe. We conducted 30 confidential interviews (10 participants in each group), with part of the interview guide focused on communication of pesticide risk to the general public and the ideas experts in the field of risk assessment and management hold of the public perception of pesticides. We used the key informant approach in recruiting our participants. They were first identified as key stakeholders in ecological risk assessment of pesticides and then sampled by means of a snowball sampling technique. In the analysis, first we identified main motifs (themes) in each group, and then we moved to studying length of the sentences and grammar and to uncovering discourses present in the text data. We also used the Flesch Reading Ease test to determine the comprehension difficulty of transcribed interviews. The test is commonly used as a standard for estimating the readability of technical documents. Our results highlight 3 main obstacles standing in the way of effective communication with wider audiences. First of all, ecological risk assessment as a highly technical procedure uses the specific language of ecological risk assessment, which is also highly specialized and might be difficult to comprehend by nonexperts. Second, the idea of existing "expert-lay discrepancy," a phenomenon described in risk perception studies is visibly present in the experts' opinions. Finally, the communication flow among stakeholders was perceived as flawed, e.g., our participants did not consider themselves fully included in the communication process, despite taking part in many networks. Interestingly, both studies on the role of trust in risk perception, and research on links between daily choices and perceived risk, show that the public is more likely to rely on experts they can trust, than the experts in our study were inclined to think. © 2013 SETAC.

Abstract Background: Prior research suggests that women do not accurately estimate their risk for breast cancer. Estimating and informing women of their risk is essential for tailoring appropriate screening and risk reduction strategies. Methods: Data were collected for BreastCARE, a randomized controlled trial designed to evaluate a PC-tablet based intervention providing multiethnic women and their primary care physicians with tailored information about breast cancer risk. We included women ages 40–74 visiting general internal medicine primary care clinics at one academic practice and one safety net practice who spoke English, Spanish, or Cantonese, and had no personal history of breast cancer. We collected baseline information regarding risk perception and concern. Women were categorized as high risk (vs. average risk) if their family history met criteria for referral to genetic counseling or if they were in the top 5% of risk for their age based on the Gail or Breast Cancer Surveillance Consortium Model (BCSC) breast cancer risk model. Results: Of 1,261 participants, 25% (N=314) were classified as high risk. More average risk than high risk women had correct risk perception (72% vs. 18%); 25% of both average and high risk women reported being very concerned about breast cancer. Average risk women with correct risk perception were less likely to be concerned about breast cancer (odds ratio [OR]=0.3; 95% confidence interval [CI]=0.2–0.4) while high risk women with correct risk perception were more likely to be concerned about breast cancer (OR=5.1; 95%CI=2.7–9.6). Conclusions: Many women did not accurately perceive their risk for breast cancer. Women with accurate risk perception had an appropriate level of concern about breast cancer. Improved methods of assessing and informing women of their breast cancer risk could motivate high risk women to apply appropriate prevention strategies and allay unnecessary concern among average risk women.

To assess the impact of direct-to-consumer (DTC) predictive genomic risk information on perceived risk and worry in the context of routine clinical care. Patients attending a preventive medicine clinic between June 1 and December 18, 2009, were randomly assigned to receive either genomic risk information from a DTC product plus usual care (n=74) or usual care alone (n=76). At intervals of 1 week and 1 year after their clinic visit, participants completed surveys containing validated measures of risk perception and levels of worry associated with the 12 conditions assessed by the DTC product. Of 345 patients approached, 150 (43%) agreed to participate, 64 (19%) refused, and 131 (38%) did not respond. Compared with those receiving usual care, participants who received genomic risk information initially rated their risk as higher for 4 conditions (abdominal aneurysm [P=.001], Graves disease [P=.04], obesity [P=.01], and osteoarthritis [P=.04]) and lower for one (prostate cancer [P=.02]). Although differences were not significant, they also reported higher levels of worry for 7 conditions and lower levels for 5 others. At 1 year, there were no significant differences between groups. Predictive genomic risk information modestly influences risk perception and worry. The extent and direction of this influence may depend on the condition being tested and its baseline prominence in preventive health care and may attenuate with time.

Gender differences in oxytocin-associated disruption of decision bias during emotion perception

Oxytocin is associated with differences in the perception of and response to socially mediated information, such as facial expressions. Across studies, however, oxytocin’s effect on emotion perception has been inconsistent. Outside the laboratory, emotion perception involves interpretation of perceptual uncertainty and assessment of behavioral risk. An account of these factors is largely missing from studies of oxytocin’s effect on emotion perception and might explain inconsistent results across studies. Of relevance, studies of oxytocin’s effect on learning and decision-making indicate that oxytocin attenuates risk aversion. We used the probability of encountering angry faces and the cost of misidentifying them as not angry to create a risky environment wherein bias to categorize faces as angry would maximize point earnings. Consistent with an underestimation of the factors creating risk (i.e., encounter rate and cost), men given oxytocin exhibited a worse (i.e., less liberal) response bias than men given placebo. Oxytocin did not influence women’s performance. These results suggest that oxytocin may impair men’s ability to adapt to changes in risk and uncertainty when introduced to novel or changing social environments. Because oxytocin also influences behavior in non-social realms, oxytocin pharmacotherapy could have unintended consequences (i.e., risk-prone decision-making) while nonetheless normalizing pathological social interaction.

Identification of risk factors for decline in health status by profiling illness perceptions before and one year after heart valve replacement surgery. Prospective data from N=225 consecutively admitted first time valve replacement patients was assessed before and one year after surgery. Patients were asked about their illness perceptions (Illness Perception Questionnaire-Revised) and mood state (Hospital Anxiety and Depression Scale). Health status was defined by quality of life (Short-Form 36) and New York Heart Association (NYHA) class. Cluster analyses were conducted to identify illness perception profiles over time. Predictors of health status after surgery were analyzed with multivariate methods. Patients were grouped according to the stability and nature (positive, negative) of their illness perception profile over one year. One year after surgery patients holding a negative illness perception profile showed a lower physical quality of life and were diagnosed in a higher New York Heart Association class than patients changing to positive and patients with stable positive illness perceptions (P<.001). Over and above biological determinants, post-surgery physical quality of life and NYHA class were both predicted by pre-surgery illness perception profiles (P<.05). Patients going for heart valve replacement surgery can be easily categorized into illness perception profiles that predict health status one year after surgery. These patients could benefit from early screening as negative illness perceptions are modifiable risk factors. Copyright © 2012 Elsevier Inc. All rights reserved.

Purpose To estimate the effects of a tablet-based, breast cancer risk education intervention for use in primary care settings (BreastCARE) on patients' breast cancer knowledge, risk perception and concern. Methods From June 2011–August 2012, we enrolled women from two clinics, aged 40–74 years with no personal breast cancer history, and randomized them to the BreastCARE intervention group or to the control group. All patients completed a baseline telephone survey and risk assessment (via telephone for controls, via tablet computer in clinic waiting room prior to visit for intervention). All women were categorized as high or average risk based on the Referral Screening Tool, the Gail model or the Breast Cancer Surveillance Consortium model. Intervention patients and their physicians received an individualized risk report to discuss during the visit. All women completed a follow-up telephone survey 1–2 weeks after risk assessment. Post-test comparisons estimated differences at follow-up in breast cancer knowledge, risk perception and concern. Results 580 intervention and 655 control women completed follow-up interviews. Mean age was 56 years (SD = 9). At follow-up, 73% of controls and 71% of intervention women correctly perceived their breast cancer risk and 22% of controls and 24% of intervention women were very concerned about breast cancer. Intervention patients had greater knowledge (≥75% correct answers) of breast cancer risk factors at follow-up (24% vs. 16%; p = 0.002). In multivariable analysis, there were no differences in correct risk perception or concern, but intervention patients had greater knowledge ([OR] = 1.62; 95% [CI] = 1.19–2.23). Conclusions A simple, practical intervention involving physicians at the point of care can improve knowledge of breast cancer without increasing concern.

At follow-up, 73% of controls and 71% of intervention women correctly perceived their breast cancer risk and 22% of controls and 24% of intervention women were very concerned about breast cancer. Intervention patients had greater knowledge (≥75% correct answers) of breast cancer risk factors at follow-up (24% vs. 16%; p = 0.002). In multivariable analysis, there were no differences in correct risk perception or concern, but intervention patients had greater knowledge ([OR] = 1.62; 95% [CI] = 1.19-2.23). A simple, practical intervention involving physicians at the point of care can improve knowledge of breast cancer without increasing concern. ClinicalTrials.gov identifier NCT01830933.

A holistic risk assessment of surface water (SW) contamination due to lead-210 (Pb-210) in oil produced water (PW) from the Bakken Shale in North Dakota (ND) was conducted. Pb-210 is a relatively long-lived radionuclide and very mobile in water. Because of limited data on Pb-210, a simulation model was developed to determine its concentration based on its parent radium-226 and historical total dissolved solids levels in PW. Scenarios where PW spills could reach SW were analyzed by applying the four steps of the risk assessment process. These scenarios are: (1) storage tank overflow, (2) leakage in equipment, and (3) spills related to trucks used to transport PW. Furthermore, a survey was conducted in ND to quantify the risk perception of PW from different stakeholders. Findings from the study include a low probability of a PW spill reaching SW and simulated concentration of Pb-210 in drinking water higher than the recommended value established by the World Health Organization. Also, after including the results from the risk perception survey, the assessment indicates that the risk of contamination of the three scenarios evaluated is between medium-high to high.

Objective To carry out a diagnosis of children's environmental health and an analysis of risk perception in indigenous communities of the Huasteca Sur region of San Luis Potosí, Mexico, in order to design an intervention strategy in line with their needs. Methods The study used mixed methods research, carried out in two phases. It was conducted in three indigenous communities of Tancanhuitz municipality from January 2005 to June 2006. In the adult population, risk perception was analyzed through focus groups, in-depth interviews, and questionnaires. In the child population, analysis of children's drawings was used to study perception. An assessment of health risks was carried out through biological monitoring and environmental monitoring of water and soil. Results The three communities face critical problems that reveal their vulnerability. When the results were triangulated and integrated, it was found that the principal problems relate to exposure to pathogenic microorganisms in water and soil, exposure to indoor wood smoke, exposure to smoke from the burning of refuse, use of insecticides, exposure to lead from the use of glazed ceramics, and alcoholism. Conclusions To ensure that the intervention strategy is adapted to the target population, it is essential to incorporate risk perception analysis and to promote the participation of community members. The proposed intervention strategy to address the detected problems is based on the principles of risk communication, community participation, and interinstitutional linkage.

Midwives' and obstetricians' perceptions of risk and its impact on clinical practice and decision-making in labour: An integrative review.

Risk and risk assessment are increasingly affecting how maternity services are governed with rates of intervention continuing to rise in obstetric-led services for low-risk women. This review synthesises original research that examines how perceptions of risk impact on midwives' and obstetricians' facilitation of care for low-risk women in labour. A five stage process for conducting integrative reviews was employed. A robust search strategy incorporated electronic searches in The Cochrane Database of Systematic Reviews, EBSCO, EMBASE and Scopus from 2009 to 2014. The initial search resulted in the retrieval of 2429 articles which were reduced to 14 through a systematic process. The results of this review revealed an over-arching theme of an assumption of abnormality in the birthing process leading to unnecessary intervention and surveillance. Three sub-themes are presented under this central theme - (1) external influences on risk perception that include practice guidelines and professional responsibility; (2) influence of personal fears and values on risk perception focusing on differing attitudes to physiological birth; (3) impact of professionals' perceptions of risk on women's decision-making in labour. Practice is influenced by an assumption of birth as abnormal and is compounded by issues such as institutional risk management, lack of midwifery responsibility, fear of involvement in adverse outcomes and personal values regarding physiological birth. These findings suggest that a shift in focus away from risk and towards health and wellbeing in the planning of maternity care may go some way towards providing a solution to the increasing intervention rates for low-risk women.

Balancing treatment benefits and risks is part of a shared decision-making process before initiating any treatment in multiple sclerosis (MS). Patients understand, appreciate and profit from evidence-based patient information (EBPI). While these processes are well known, long-term risk awareness and risk processing of patients has not been studied. Mitoxantrone treatment in MS is associated with long-term major potential harms - leukaemia (LK) and cardiotoxicity (CT). The risk knowledge and perception among patients currently or previously treated with mitoxantrone is unknown. The objective of this article is to conduct a retrospective cohort study in greater Hamburg, Germany, to estimate risk awareness and perception in MS patients treated with mitoxantrone. MS patients with at least one dose of mitoxantrone between 1991 and 2010 from six major MS centres in greater Hamburg received a questionnaire assessing risk awareness and perception as well as a written EBPI about mitoxantrone-associated LK and CT. Fifty-one per cent in the cohort of n = 575 patients returned the questionnaire. Forty per cent correctly estimated the risk of LK (CT 16%); 56% underestimated the risk (CT 82%). Reading the information increased the accuracy of LK risk estimation, and patients did not report an increase of worries. The EBPI was appreciated and recommended by 85%. Risk awareness of mitoxantrone-treated patients is insufficient, but can be increased by EBPI without increasing worries. Continued patient information during and after treatment should be implemented in management algorithms.

Perceptions of environmental health risks among residents in the "Toxic Doughnut": opportunities for risk screening and community mobilization.

Surrounded by landfills, and toxic and hazardous facilities, Altgeld Gardens is located in a "toxic doughnut". With high rates of environmentally-related conditions, residents have called for a community-based environmental health assessment to improve overall health in their community. The purpose of this study was to investigate the attitudes and beliefs of environmental health risks of Altgeld's residents which would assist community organizing efforts and provide the groundwork for a community-based environmental health assessment. A questionnaire was designed and administered to 42 Altgeld residents who also participated in focus groups to assess their perceptions of environmental health risks. All participants were Altgeld residents for at least two years and were fairly representative of the broader community. Physical and social hazards were primarily identified as posing risks to participants' family and the broader community. Physical hazards included the dumping of hazardous waste and landfills; social hazards were crime and drugs. These findings have been useful in community organizing efforts and in program planning for local community-based organizations and public health agencies. The results have also been used to prioritize health and environmental risk issues impacting the community.

Little is known about different ways of assessing risk of distant recurrence following cancer treatment (e.g., numeric or descriptive). We sought to evaluate the association between overestimation of risk of distant recurrence of breast cancer and key patient-reported outcomes, including quality of life and worry. We surveyed a weighted random sample of newly diagnosed patients with early-stage breast cancer identified through SEER registries of Los Angeles County & Georgia (2013-14) ~2 months after surgery (N = 2578, RR = 71%). Actual 10-year risk of distant recurrence after treatment was based on clinical factors for women with DCIS & low-risk invasive cancer (Stg 1A, ER+, HER2-, Gr 1-2). Women reported perceptions of their risk numerically (0-100%), with values ≥10% for DCIS & ≥20% for invasive considered overestimates. Perceptions of "moderate, high or very high" risk were considered descriptive overestimates. In our analytic sample (N = 927), we assessed factors correlated with both types of overestimation and report multivariable associations between overestimation and QoL (PROMIS physical & mental health) and frequent worry. 30.4% of women substantially overestimated their risk of distant recurrence numerically and 14.7% descriptively. Few factors other than family history were significantly associated with either type of overestimation. Both types of overestimation were significantly associated with frequent worry, and lower QoL. Ensuring understanding of systemic recurrence risk, particularly among patients with favorable prognosis, is important. Better risk communication by clinicians may translate to better risk comprehension among patients and to improvements in QoL.

Air pollution is among the leading global risks for mortality and responsible for increasing risk for chronic diseases. Community perceptions on exposure are critical in determining people’s response and acceptance of related policies. Therefore, understanding people’ perception is critical in informing the design of appropriate intervention measures. The aim of this paper was to establish levels and associations between perceived pollution and health risk perception among slum residents. A cross-sectional study of 5,317 individuals aged 35+ years was conducted in two slums of Nairobi. Association of perceived score and individual characteristics was assessed using linear regression. Spatial variation in the perceived levels was determined through hot spot analysis using ArcGIS. The average perceived air pollution level was higher among residents in Viwandani compared to those in Korogocho. Perceived air pollution level was positively associated with perceived health risks. The majority of respondents were exposed to air pollution in their place of work with 66% exposed to at least two sources of air pollution. Less than 20% of the respondents in both areas mentioned sources related to indoor pollution. The perceived air pollution level and related health risks in the study community were lowamong the residents indicating the need for promoting awareness on air pollution sources and related health risks.

There is increasing interest in combining postmenopausal hormone therapy (HT) and SERMs in midlife women. We previously showed that refusal to participate in a prevention trial of low dose tamoxifen in HT users was associated with higher worry about breast cancer. Given this counterintuitive finding, we studied which factors influenced worry and risk perception of breast cancer. We assessed the relationships of breast cancer worry and risk perception with age, age at menopause, Gail risk, education, adherence to mammographic screening, BMI, smoking, physical activity, alcohol use, anxiety and depression in 457 midlife HT users who were eligible to participate in the trial. Women with menopause <48 years were more worried about breast cancer than women with menopause >52 years (OR = 5.0, 95% CI, 1.2-21.1). Worry was also associated with high absolute risk perception and former smoking. Factors associated with higher risk perception were age>60 years, at-risk life style, worry about breast cancer and depression. The inverse association between early menopause and worry about breast cancer is in contrast with the known protective effect of early menopause on breast cancer risk and seems to reflect a feeling of aging and disease vulnerability. Our findings indicate that worry about cancer has an affective construct which is independent of breast cancer biology but is engaged in health decision making. Increasing breast cancer risk awareness in subjects high in worry without a plan of emotional coping may therefore be counterproductive because of avoidant attitudes. Copyright © 2017.

To assess the effects of an interprofessional student-led comprehensive sexual education curriculum in improving the reproductive health literacy among at-risk youths in detention. We performed a prospective cohort study involving 134 incarcerated youth and an interprofessional team of 23 medical, nursing, and social work students, who participated in a comprehensive reproductive health curriculum over the course of 3 days. Basic reproductive health knowledge, confidence in condom use with a new partner, and self-efficacy with regard to contraception use and sexual autonomy were assessed before and after completion of the curriculum. We also assessed the student teachers' level of comfort with teaching reproductive health to adolescents and their perception of interprofessionalism. Incarcerated youth showed a statistically significant increase in knowledge regarding sexually transmitted infections as well as self-reported confidence in condom use (P = .002). Self-efficacy in contraception use and sexual autonomy did not show significant improvement. Qualitative analysis of student teachers' surveys revealed theme categories regarding perception of youth, perception of self in teaching youth, perception of interacting with youth, and perception of working in interprofessional teams. Our program might represent a mutually beneficial community relationship to improve reproductive health literacy in this high-risk youth population.

Infectious respiratory disease outbreaks and pregnancy: occupational health and safety concerns of Canadian nurses.

2011-04-01

This paper is a report of a qualitative study of emergency and critical care nurses' perceptions of occupational response and preparedness during infectious respiratory disease outbreaks including severe acute respiratory syndrome (SARS) and influenza. Healthcare workers, predominantly female, face occupational and personal challenges in their roles as first responders/first receivers. Exposure to SARS or other respiratory pathogens during pregnancy represents additional occupational risk for healthcare workers. Perceptions of occupational reproductive risk during response to infectious respiratory disease outbreaks were assessed qualitatively by five focus groups comprised of 100 Canadian nurses conducted between 2005 and 2006. Occupational health and safety issues anticipated by Canadian nurses for future infectious respiratory disease outbreaks were grouped into four major themes: (1) apprehension about occupational risks to pregnant nurses; (2) unknown pregnancy risks of anti-infective therapy/prophylaxis; (3) occupational risk communication for pregnant nurses; and (4) human resource strategies required for pregnant nurses during outbreaks. The reproductive risk perceptions voiced by Canadian nurses generally were consistent with reported case reports of pregnant women infected with SARS or emerging influenza strains. Nurses' fears of fertility risks posed by exposure to infectious agents or anti-infective therapy and prophylaxis are not well supported by the literature, with the former not biologically plausible and the latter lacking sufficient data. Reproductive risk assessments should be performed for each infectious respiratory disease outbreak to provide female healthcare workers and in particular pregnant women with guidelines regarding infection control and use of anti-infective therapy and prophylaxis.

Global motion perception is often used as an index of dorsal visual stream function in neurodevelopmental studies. However, the relationship between global motion perception and visuomotor control, a primary function of the dorsal stream, is unclear. We measured global motion perception (motion coherence threshold; MCT) and performance on standardized measures of motor function in 606 4.5-year-old children born at risk of abnormal neurodevelopment. Visual acuity, stereoacuity and verbal IQ were also assessed. After adjustment for verbal IQ or both visual acuity and stereoacuity, MCT was modestly, but significantly, associated with all components of motor function with the exception of gross motor scores. In a separate analysis, stereoacuity, but not visual acuity, was significantly associated with both gross and fine motor scores. These results indicate that the development of motion perception and stereoacuity are associated with motor function in pre-school children. PMID:28435122

Many women overestimate their percentage risk of breast cancer, even after they have received careful estimates from health professionals. In 2 experiments with 134 young adult women, 6 variables were explored that might influence such risk perception persistence. In Study 1, each of the following explanations was unrelated to persistence: public commitment, self-consistency, and unique causal risk models. In Study 2, two individual difference measures, pessimism and differences in understanding percentages, were unrelated to risk perception persistence. However, providing a "risk anchor" based on downward social comparison processes resulted in better risk acceptance at posttest that persisted at a 2-week follow-up assessment. This article discusses why comparison anchors might be important in risk feedback situations and concludes with recommendations for professionals who wish to provide accurate risk information and have patients adopt that information.

Land degradation due to erosion in public perception. Case study: Secaşul Mare river basin settlements (Transylvanian Depression, Romania).

According to the International Decade for Natural Disaster Reduction (IDNDR 1990-1999), the risk indicates potential losses due to particular natural phenomenon, and these could be reduced by improving of prevention and education. People perceive these losses differently depending on phenomenon occurrence, severity, and impact in time. Starting from this idea, this research presents public perception on land degradation through erosion in a small area from the central part of Romania (south-west of Transylvanian Depression). The research was based on a questionnaire consisting of 16 questions. The items were structured by issues: awareness assessment regarding hazard and risk phenomena, assessment of type of property and land use, assessment of knowledge and information on the possible production of negative effects by natural phenomena, and evaluation of land owners' attitudes towards the occurrence of erosion on their land. Results reveal that the public perception on erosion is weak. This process is perceived as insignificant due to lack of phenomenon knowledge and especially because of scarcity preoccupation in land's quality monitoring. Even though the owned lands are affected by erosion forms, the owners are not aware of the phenomenon that generates them. Material damages caused by erosion, loss of soil quality, and land fertility decrease are less perceived because the economic losses fill only at long term. This perception leads to underestimating erosion risk compared to other natural phenomena and to a passive attitude towards this particular phenomenon.

Nanomaterials in agriculture and food are key issues of public and regulatory interest. Over the past ten years, patents for nanotechnological applications in the field of food and agriculture have become abundant. Uncertainty prevails however regarding their current development status and presence in the consumer market. Thus, the discussion on nanotechnologies in the food sector with its specific public perception of benefits and risks and the patterns of communication are becoming similar to the debate on genetically modified organisms. The food industry's silence in communication increased mistrust of consumer organisations and policy makers. The article discusses the background of the current regulatory debates, starting with the EU recommendation for defining nanomaterials, provides an overview of possible fields of application in agriculture and food industries and discusses risk assessment and the public debate on benefits and risks. Communicative recommendations are directed at researchers, the food industry and regulators in order to increase trust both in stakeholders, risk management and regulatory processes.

To assess factors associated with a low risk perception of zoonoses and to identify the gaps in knowledge about transmission and prevention of zoonoses in immigrant and Italian workers. A cross-sectional study with 175 workers in the agro-livestock and agro-food industry in Piemonte, Italy, was carried out. Data were collected with a semi-structured questionnaire based on knowledge, attitudes and practices (KAP) survey. We calculated proportions and used chi-square tests and odds ratios to assess associations. Eight individual interviews with key informants on immigration and public health in Piemonte were carried out. Participants were 82 (47%) Italians and 93 (53%) immigrants. Immigrants were from Romania, Morocco, Albania, India, China, Argentina, Peru, Macedonia, Ivory Coast, Ukraine and Colombia. The study revealed significant differences in risk perception at work (p = 0.001). We found associations between "not having correct knowledge about zoonoses" and the following variables: i. "being immigrant" OR = 4.1 (95%CI 1.7;9.8 p ≤ 0.01); ii. "working in the livestock industry" OR = 2.9 (95%CI 1.2;15.4 p = 0.01); and iii. "being an unqualified worker" OR = 4.4 (95%CI 2.9;15.4 p ≤ 0.01). Another strong association was found between being immigrant and having a low job qualification OR = 6.7 (IC95% 2.9 - 15.4 p ≤ 0.01). Asian immigrants were the group with the highest frequency of risky behaviours and the lowest level of knowledge about zoonoses. Our results indicate that there were differences in risk perception of zoonoses between the groups participating in our study. These results suggest that immigrant status can be considered a risk factor for having lower risk perception and lower level of knowledge of zoonoses at work. There is a relationship between this specific knowledge of zoonoses and lack of training and instruction among migrant populations. Our results stress the need for developing education programs on zoonoses prevention among the immigrant population in Piemonte, Italy.

What works best: objective statistics or a personal testimonial? An assessment of the persuasive effects of different types of message evidence on risk perception.

In an experimental online study we compared the effects of different types of persuasive evidence in promoting the acceptance of a personal health risk. 118 men who have sex with men (MSM) at-risk for infection with the hepatitis B virus (HBV) were recruited via a range of websites and randomly assigned to one of 4 conditions (2 experimental and 2 control): narrative evidence (i.e., a personal account), statistical evidence (i.e., abstract prevalence data), mere assertion of increased risk, and no risk information. Narrative evidence was expected to be more effective than statistical evidence in increasing MSM's perceived risk of infection with HBV and intention to obtain vaccination. As predicted, perceptions of personal risk and intention to obtain vaccination against HBV were highest after presentation of narrative evidence, and risk perception mediated the effect of type of message evidence on intention. We propose that narrative evidence effectively promotes a sense of personal risk because it is less affected by defensive message processing resulting from the threat to important self-beliefs that seems inherent in health risk communication.

This study assessed the computer/mobile device screen time and eye care behavior of children and examined the roles of risk perception and parental practices. Data were obtained from a sample of 2,454 child-parent dyads recruited from 30 primary schools in Taipei city and New Taipei city, Taiwan, in 2016. Self-administered questionnaires were collected from students and parents. Fifth-grade students spend more time on new media (computer/smartphone/tablet: 16 hours a week) than on traditional media (television: 10 hours a week). The average daily screen time (3.5 hours) for these children exceeded the American Academy of Pediatrics recommendations (≤2 hours). Multivariate analysis results showed that after controlling for demographic factors, the parents with higher levels of risk perception and parental efficacy were more likely to mediate their child's eye care behavior. Children who reported lower academic performance, who were from non-intact families, reported lower levels of risk perception of mobile device use, had parents who spent more time using computers and mobile devices, and had lower levels of parental mediation were more likely to spend more time using computers and mobile devices; whereas children who reported higher academic performance, higher levels of risk perception, and higher levels of parental mediation were more likely to engage in higher levels of eye care behavior. Risk perception by children and parental practices are associated with the amount of screen time that children regularly engage in and their level of eye care behavior.

Risk perceptions are legitimate targets for behavioral interventions because they can motivate medical decisions and health behaviors. However, some survey respondents may not know (or may not indicate) their risk perceptions. The scope of "don't know" (DK) responding is unknown. Examine the prevalence and correlates of responding DK to items assessing perceived risk of colorectal cancer. Two nationally representative, population-based, cross-sectional surveys (2005 National Health Interview Survey [NHIS]; 2005 Health Information National Trends Survey [HINTS]), and one primary care clinic-based survey comprised of individuals from low-income communities. Analyses included 31,202 (NHIS), 1,937 (HINTS), and 769 (clinic) individuals. Five items assessed perceived risk of colorectal cancer. Four of the items differed in format and/or response scale: comparative risk (NHIS, HINTS); absolute risk (HINTS, clinic), and "likelihood" and "chance" response scales (clinic). Only the clinic-based survey included an explicit DK response option. "Don't know" responding was 6.9% (NHIS), 7.5% (HINTS-comparative), and 8.7% (HINTS-absolute). "Don't know" responding was 49.1% and 69.3% for the "chance" and "likely" response options (clinic). Correlates of DK responding were characteristics generally associated with disparities (e.g., low education), but the pattern of results varied among samples, question formats, and response scales. The surveys were developed independently and employed different methodologies and items. Consequently, the results were not directly comparable. There may be multiple explanations for differences in the magnitude and characteristics of DK responding. "Don't know" responding is more prevalent in populations affected by health disparities. Either not assessing or not analyzing DK responses could further disenfranchise these populations and negatively affect the validity of research and the efficacy of interventions seeking to eliminate health disparities.

There is a need to involve sexual partners when addressing sexual behavior of high-risk adolescent women. This study explored men's perceptions of their role in sexual relationships with adolescent women with a history of sexually transmitted infection (STI) and abuse. The AIDS risk reduction model was used to assess sexual risk behaviors of these men for development of cognitive behavioral risk reduction interventions for themselves and partner. Qualitative interviews were conducted with African and Mexican American men (n = 14; ages 18 to 21 years), recruited via adolescent women enrolled in a control-randomized trial of behavioral interventions for reduction of unintended pregnancy, abuse, substance use, and STI. Participants varied in their perceptions of personal susceptibility to STI or HIV, access to informational resources regarding sexual behavior, and level of adult support for safer sexual behavior. These men shared perceptions of inadequate sexual health preparation, including education concerning risk, ultimately contributing to adverse outcomes of sexual behavior.

Objectives Studies in the U.S. have found that white men are less concerned about pollution than are women or people of other ethnicity. These studies have not assessed respondents’ proximity to localized sources of pollution. Our objective was to assess lay perceptions of risk from air pollution in an ethnically diverse sample in which proximity to a major perceptible source of pollution is known. Methods Cross sectional interview study of combined area probability and convenience sample of individuals 40 and older in the Boston area, selected according to proximity to high traffic controlled access highways. Results Of 697 respondents 46% were white, 37% Asian (mostly Chinese), 6.3% African-American, 6.3% Latino, and 7.6% other ethnicity. While white respondents, and particularly white men, were less concerned about air pollution than others, this effect disappeared when controlling for distance from the highway. White men were slightly less supportive than others of government policy to control pollution Conclusions The “white male” effect may in part be accounted for by the greater likelihood of minority respondents to live near perceptible localized sources of pollution.

Background Comparative risk perceptions may rival other types of information in terms of effects on health behavior decisions. Purpose We examined associations between comparative risk perceptions, affect, and behavior while controlling for absolute risk perceptions and actual risk. Methods Women at an increased risk of breast cancer participated in a program to learn about tamoxifen which can reduce the risk of breast cancer. Women reported comparative risk perceptions of breast cancer and completed measures of anxiety, knowledge, and tamoxifen-related behavior intentions. Three months later, women reported their behavior. Results Comparative risk perceptions were positively correlated with anxiety, knowledge, intentions, and behavior three months later. After controlling for participants’ actual risk of breast cancer and absolute risk perceptions, comparative risk perceptions predicted anxiety and knowledge, but not intentions or behavior. Conclusions Comparative risk perceptions can affect patient outcomes like anxiety and knowledge independently of absolute risk perceptions and actual risk information. PMID:21698518

Risk assessment with victims of intimate partner violence: investigating the gap between research and practice.

Cattaneo, Lauren Bennett; Chapman, Aliya R

2011-10-01

In intimate partner violence (IPV) risk assessment, there is consensus that a large gap exists between research and practice. This exploratory study interviewed 13 practitioners working with IPV victims to generate ideas about the nature of this gap, and found that only two conducted standardized risk assessment. Others felt imposing structure might detract from the quality of their work. Results support the need for different techniques in different contexts; some adjust only speed of services according to their risk perception, whereas others use in-depth information to customize services. Perspectives appear particularly disparate regarding victim minimization of risk. Implications for future work are discussed.

The management of healthcare wastes is receiving greater attention because of the risks to both human health and the environment caused by inadequate waste management practices. In that context, the objective of this study was to analyse the healthcare waste management practices in hospitals of the Algarve region, Portugal, and in particular to assess the risk perceptions of, and actual risk to, healthcare staff. The study included three of the six hospitals in the region, covering 41% of the bed capacity. Data were collected via surveys, interviews, and on-site observations. The results indicate that waste separation is the main deficiency in healthcare waste practice, with correct separation being positively related to the degree of daily contact with the waste. Risk perceptions of healthcare staff show the highest levels for the environment (4.24) and waste workers (4.08), and the lowest for patients (3.29) and visitors (2.80), again being positively associated with the degree of daily contact. Risk perceptions of healthcare staff are related to the difficulties of the correct separation of wastes and the lack of knowledge concerning the importance of that separation. The risk of infection with needlesticks/sharps is higher during patient care than during waste handling, and the frequency of these injuries is related to the daily tasks of each healthcare group (doctors, nurses, and housekeepers). Furthermore, legislative definitions and classifications of healthcare wastes appear to have conditioned the management practices associated with, and the perceptions of risk concerning, healthcare wastes.

As a tropical archipelagic nation, the Philippines is particularly susceptible to coastal hazards, which are likely to be exacerbated by climate change. To improve coastal hazard management and adaptation planning, it is imperative that climate information be provided at relevant scales and that decision-makers understand the causes and nature of risk in their constituencies. Focusing on a municipality in the Central Philippines, this study examines local meteorological information and explores household perceptions of climate change and coastal hazard risk. First, meteorological data and local perceptions of changing climate conditions are assessed. Perceived changes in climate include an increase in rainfall and rainfall variability, an increase in intensity and frequency of storm events and sea level rise. Second, factors affecting climate change perceptions and perceived risk from coastal hazards are determined through statistical analysis. Factors tested include social status, economic standing, resource dependency and spatial location. Results indicate that perceived risk to coastal hazards is most affected by households' spatial location and resource dependency, rather than socio-economic conditions. However, important differences exist based on the type of hazard and nature of risk being measured. Resource dependency variables are more significant in determining perceived risk from coastal erosion and sea level rise than flood events. Spatial location is most significant in determining households' perceived risk to their household assets, but not perceived risk to their livelihood. Copyright © 2012 Elsevier Ltd.

This study's purpose was to examine the predictive validity and clinical utility of a brief measure assessing youths' own expectations of their future risk of suicidal behavior, administered in a psychiatric emergency (PE) department; and determine if youths' ratings improve upon a clinician-administered assessment of suicidal ideation severity. The outcome was suicide attempts up to 18 months later. In this medical record review study, 340 consecutively presenting youths (ages 13-24) seeking PE services over a 7-month period were included. Subsequent PE visits and suicide attempts were retrospectively tracked for up to 18 months. The 3-item scale assessing patients' perception of their own suicidal behavior risk and the clinician-administered ideation severity scale were used routinely at the study site. Cox regression results showed that youths' expectations of suicidal behavior were independently associated with increased risk of suicide attempts, even after adjusting for key covariates. Results were not moderated by sex, suicide attempt history, or age. Receiver-operating characteristic (ROC) analyses indicated that self-assessed expectations of risk improved the predictive accuracy of the clinician-administered suicidal ideation measure. Youths' ratings indicative of lower confidence in maintaining safety uniquely predicted follow-up attempts and provided incremental validity over and above the clinician-administered assessment and improved its accuracy, suggesting their potential for augmenting suicide risk formulation. Assessing youths' own perceptions of suicide risk appears to be clinically useful, feasible to implement in PE settings, and, if replicated, promising for improving identification of youth at risk for suicidal behavior. © 2016 Wiley Periodicals, Inc.

Attentional deficits with and without hyperactivity: teacher and peer perceptions.

King, C; Young, R D

1982-12-01

The present study assessed teacher and peer perceptions of boys classified according to DSM-III criteria for Attention Deficit with Hyperactivity (ADH) and Attention Deficit without Hyperactivity (AD). Teachers completed SNAP checklists (Pelham, Note 1) on all boys in their classrooms (219 boys). Twelve percent fit ADH criteria; less than 5% fit AD criteria. Teacher perceptions were assessed with the Conners Teacher Rating Scale. ADH and AD groups did not differ on the Inattention factor, although the AD group was rated significantly lower than the ADH group on Conduct Problems and Hyperactivity. These profiles were expected on the basis of DSM-III descriptions of ADH and AD; the ADH group seemed to resemble previous research samples of hyperactive children. Classroom peer perceptions, assessed with like-dislike nominations, did not discriminate between diagnostic groups. Both groups were perceived more negatively than the Comparison group, suggesting that both groups are "at risk."

The relationship of tobacco and alcohol use with ageing self-perceptions in older people in Ireland.

Health behaviour patterns in older groups, including tobacco and alcohol use, are key factors in chronic disease prevention. We explore ageing self-perceptions as motivating factors behind smoking and drinking alcohol in older adults, and the complex reasons why individuals engage harmfully in these behaviours. Cigarette and alcohol use was assessed in a large cross-sectional national sample aged 50 years and above from the Irish Longitudinal Study on Ageing (TILDA) (n = 6,576). The Brief Ageing Perceptions Questionnaire (BAPQ) assessed individual's views of their own ageing across five domains. Study hypothesis that stronger beliefs on each of the BAPQ domains would be related to drinking and smoking was examined using multinomial logit models (MNLM). Regression parameter estimates for all variables were estimated relative risk ratios (RRR). More women were non-drinkers (30 % vs. 20 %) and men displayed significantly higher alcohol use patterns. One in five older Irish adults was a current smoker (16.8 % of women, 17 % of men), and smoking and harmful drinking were strongly associated (P < .001). Some domains of ageing perceptions were significantly associated with harmful drinking and smoking. While the risk of being be harmful drinker decreased with stronger beliefs about the positive consequences of ageing (RRR 0.89), it increased with higher scores on both emotional representation and control positive domains. Greater awareness of ageing and stronger emotional reaction to ageing increased likelihood of smoking. A greater sense of control over the outcomes of ageing was associated with increased risk of both harmful drinking (RRR control positive 1.16) and smoking (RRR control and consequences negative 1.25). This suggests optimistic bias in relation to perceived health risk from smoking and harmful drinking as a potential adverse effect of perceptions of control. Risks of concurrent smoking and harmful drinking increased with chronic awareness of ageing (RRR 1.24), and negative emotional responses to it (RRR 1.21), and decreased with stronger perceptions of the positive consequences of ageing (RRR 0.85). The relationship between ageing perceptions, smoking and drinking is complex. Altering perceptions of ageing may be a useful intervention target aimed at facilitating engagement in preventative health behaviours in older people.

The impact of genetic counseling on knowledge and emotional responses in Spanish population with family history of breast cancer.

To assess a genetic counseling intervention measuring the distress, cancer risk perception, anxiety, worry and level of knowledge in people with familial history of breast cancer. One group pre- and post-test design. A total of 212 individuals completed a baseline questionnaire, 88.6% completed a second questionnaire one month later and 75.4% six months later. Counseling intervention significantly increased the knowledge level of the individuals who received genetic education and significantly decreased the cancer worry levels. Persons with low perception of their cancer risk also had low worry levels. There were no significant changes over time in cancer risk perception or in quality of life. Counseling in a high risk population seems to decrease cancer worry and to increase cancer knowledge thus enabling a counselee to take well-informed decisions. Furthermore, according to our results, such interventions do not increase anxiety and do not modify the quality of life, but do not adjust their cancer risk perception. Providing individuals at increased risk of breast cancer genetic services seem to enhance their understanding of breast cancer without causing adverse psychological effects or changes in their quality of life, and it could improve their preventive behaviours.

Game meat from animals killed by lead ammunition may expose consumers to lead. We assessed the risk related to lead intake from meat consumption of white-tailed deer and moose killed by lead ammunition and documented the perception of hunters and butchers regarding this potential contamination. Information on cervid meat consumption and risk perception were collected using a mailed self-administrated questionnaire which was addressed to a random sample of Quebec hunters. In parallel, 72 samples of white-tailed deer (n = 35) and moose (n = 37) meats were collected from voluntary hunters and analysed for lead content using inductively coupled plasma-mass spectrometry. A risk assessment for people consuming lead shot game meat was performed using Monte Carlo simulations. Mean lead levels in white-tailed deer and moose killed by lead ammunition were 0.28 and 0.17 mg kg(-1) respectively. Risk assessment based on declared cervid meat consumption revealed that 1.7% of the surveyed hunters would exceed the dose associated with a 1 mmHg increase in systolic blood pressure (SBP). For consumers of moose meat once, twice or three times a week, simulations predicted that 0.5%, 0.9% and 1.5% of adults would be exposed to a dose associated with a 1 mmHg increase in SBP, whereas 0.9%, 1.9% and 3.3% of children would be exposed to a dose associated with 1 point intelligence quotient (IQ) decrease, respectively. For consumers of deer meat once, twice or three times a week, the proportions were 1.6%, 2.9% and 4% for adults and 2.9%, 5.8% and 7.7% for children, respectively. The consumption of meat from cervids killed with lead ammunition may increase lead exposure and its associated health risks. It would be important to inform the population, particularly hunters, about this potential risk and promote the use of lead-free ammunition.

The influence of graphic format on breast cancer risk communication.

Graphic displays can enhance quantitative risk communication. However, empiric data regarding the effect of graphic format on risk perception is lacking. We evaluate the effect of graphic format elements on perceptions of risk magnitude and perceived truth of data. Preferences for format also were assessed. Participants (254 female primary care patients) viewed a series of hypothetical risk communications regarding the lifetime risk of breast cancer. Identical numeric risk information was presented using different graphic formats. Risk was perceived to be of lower magnitude when communicated with a bar graph as compared with a pictorial display (p < 0.0001), or with consecutively versus randomly highlighted symbols in a pictorial display (p = 0.0001). Data were perceived to be more true when presented with random versus consecutive highlights in a pictorial display (p < 0.01). A pictorial display was preferred to a bar graph format for the presentation of breast cancer risk estimates alone (p = 0.001). When considering breast cancer risk in comparison to heart disease, stroke, and osteoporosis, however, bar graphs were preferred pictorial displays (p < 0.001). In conclusion, elements of graphic format used to convey quantitative risk information effects key domains of risk perception. One must be cognizant of these effects when designing risk communication strategies.

OBJECTIVE: To assess the impact of direct-to-consumer (DTC) predictive genomic risk information on perceived risk and worry in the context of routine clinical care. PATIENTS AND METHODS: Patients attending a preventive medicine clinic between June 1 and December 18, 2009, were randomly assigned to receive either genomic risk information from a DTC product plus usual care (n=74) or usual care alone (n=76). At intervals of 1 week and 1 year after their clinic visit, participants completed surveys containing validated measures of risk perception and levels of worry associated with the 12 conditions assessed by the DTC product. RESULTS: Of 345 patients approached, 150 (43%) agreed to participate, 64 (19%) refused, and 131 (38%) did not respond. Compared with those receiving usual care, participants who received genomic risk information initially rated their risk as higher for 4 conditions (abdominal aneurysm [P=.001], Graves disease [P=.04], obesity [P=.01], and osteoarthritis [P=.04]) and lower for one (prostate cancer [P=.02]). Although differences were not significant, they also reported higher levels of worry for 7 conditions and lower levels for 5 others. At 1 year, there were no significant differences between groups. CONCLUSION: Predictive genomic risk information modestly influences risk perception and worry. The extent and direction of this influence may depend on the condition being tested and its baseline prominence in preventive health care and may attenuate with time.

Gender differences in oxytocin-associated disruption of decision bias during emotion perception.

Lynn, Spencer K; Hoge, Elizabeth A; Fischer, Laura E; Barrett, Lisa Feldman; Simon, Naomi M

2014-09-30

Oxytocin is associated with differences in the perception of and response to socially mediated information, such as facial expressions. Across studies, however, oxytocin׳s effect on emotion perception has been inconsistent. Outside the laboratory, emotion perception involves interpretation of perceptual uncertainty and assessment of behavioral risk. An account of these factors is largely missing from studies of oxytocin׳s effect on emotion perception and might explain inconsistent results across studies. Of relevance, studies of oxytocin׳s effect on learning and decision-making indicate that oxytocin attenuates risk aversion. We used the probability of encountering angry faces and the cost of misidentifying them as not angry to create a risky environment wherein bias to categorize faces as angry would maximize point earnings. Consistent with an underestimation of the factors creating risk (i.e., encounter rate and cost), men given oxytocin exhibited a worse (i.e., less liberal) response bias than men given placebo. Oxytocin did not influence women׳s performance. These results suggest that oxytocin may impair men׳s ability to adapt to changes in risk and uncertainty when introduced to novel or changing social environments. Because oxytocin also influences behavior in non-social realms, oxytocin pharmacotherapy could have unintended consequences (i.e., risk-prone decision-making) while nonetheless normalizing pathological social interaction.

Psychosocial factors that may affect electronic cigarette (e-cigarette) initiation or maintenance among racial/ethnic minorities are not well-understood. This study examined racial/ethnic differences in e-cigarette knowledge, risk perceptions, and social norms among current and former smokers. Individuals with a tobacco smoking history and an awareness of e-cigarettes (N=285) were recruited from the community from June to August 2014. Telephone-administered surveys assessed demographics, smoking status, and e-cigarette knowledge, risk perceptions, and normative beliefs. Analyses of covariance and multinomial logistic regression tested associations by race/ethnicity. Controlling for sociodemographics and smoking status, White participants scored significantly higher on e-cigarette knowledge, compared to both Hispanics and African Americans/Blacks. Knowledge was lower among African Americans/Blacks compared to Hispanics. Compared to both Whites and Hispanics, African American/Black participants held lower perceptions regarding e-cigarette health risks and were less likely to view e-cigarettes as addictive. Normative beliefs did not differ by race/ethnicity. In conclusion, e-cigarette knowledge, health risk perceptions, and perceived addictiveness differed by race/ethnicity. The variation in e-cigarette knowledge and beliefs among smokers and former smokers has implications for use, and potentially, dual use. Understanding these relationships in unrepresented populations can inform future research and practice. Copyright © 2017 Elsevier Ltd. All rights reserved.

Lay perceptions of predictive testing for diabetes based on DNA test results versus family history assessment: a focus group study.

This study assessed lay perceptions of issues related to predictive genetic testing for multifactorial diseases. These perceived issues may differ from the "classic" issues, e.g. autonomy, discrimination, and psychological harm that are considered important in predictive testing for monogenic disorders. In this study, type 2 diabetes was used as an example, and perceptions with regard to predictive testing based on DNA test results and family history assessment were compared. Eight focus group interviews were held with 45 individuals aged 35-70 years with (n = 3) and without (n = 1) a family history of diabetes, mixed groups of these two (n = 2), and diabetes patients (n = 2). All interviews were transcribed and analysed using Atlas-ti. Most participants believed in the ability of a predictive test to identify people at risk for diabetes and to motivate preventive behaviour. Different reasons underlying motivation were considered when comparing DNA test results and a family history risk assessment. A perceived drawback of DNA testing was that diabetes was considered not severe enough for this type of risk assessment. In addition, diabetes family history assessment was not considered useful by some participants, since there are also other risk factors involved, not everyone has a diabetes family history or knows their family history, and it might have a negative influence on family relations. Respect for autonomy of individuals was emphasized more with regard to DNA testing than family history assessment. Other issues such as psychological harm, discrimination, and privacy were only briefly mentioned for both tests. The results suggest that most participants believe a predictive genetic test could be used in the prevention of multifactorial disorders, such as diabetes, but indicate points to consider before both these tests are applied. These considerations differ with regard to the method of assessment (DNA test or obtaining family history) and also differ from monogenic disorders.

Risk perception and its role in attitudes toward blood transfusion: a qualitative systematic review.

Despite improvements in blood safety making transfusion a much safer clinical procedure, the general public still perceives it as risky. We systematically reviewed available literature to examine evidence regarding the reasons and causes behind this perception. Electronic databases including PubMed, Cochrane Library, and EMBASE for literature dating back to the 1980s were searched. Eligible studies collected information on blood recipients' demographics, measures of risk domains (sets of values that risks encompass), and general knowledge of blood transfusion in terms of risks and benefits. Each study was assessed for quality of data, research method, and relevant findings. A scoring system was used to subjectively rate the overall quality of each study. Each study was reviewed for its method of data collection and information abstracted on hazards and conceptual dimensions used to measure risk. Risk perception between blood transfusion and other hazards including alternatives to transfusion were compared. Fifteen studies met the inclusion criteria, all of which were conducted outside the United States, with most of the studies published more than 10 years ago and conducted by only 3 research groups. Five studies were rated as being very good, four good, five fair, and one of poor quality. The finding of the studies consistently show that objective or raw knowledge is not correlated with risk perception, but subjective or calibrated knowledge is. Thus, it is what people think they know rather than what they actually do know that influences risk perception of transfusion. Of the 3 common conceptual domains-dread, unknown risk, and benefits-blood transfusion was found to be of intermediate dread, intermediate unknown risk, and most beneficial compared with other hazards. Donated blood was found to have lower perceived risk than all other alternatives to transfusion, except for use of autologous blood. There is a lack of recent studies on allogeneic transfusion. However, the more recent studies show that perceived high risk is still prevalent in the general public. The available risk perception studies suggest that although blood transfusion is safe, elevated risk perception of infections persists. Studies of the US population are needed to better understand the influence of both psychological and scientific factors. Copyright © 2013 Elsevier Inc. All rights reserved.

Patients with Type 2 diabetes may play a role as intermediary between medical professionals and at-risk relatives to promote diabetes prevention in their family. This study aimed to further our understanding of factors that influence the decisional process of familial risk disclosure in patients with diabetes. In a cross-sectional study, patients with Type 2 diabetes (n = 546) filled in a questionnaire assessing family risk perception, worry, personal beliefs regarding diabetes prevention, diabetes-related family communication, intention and perceived ability to inform relatives about familial risk of diabetes. Data were analysed using hierarchical logistic regression and multiple mediation analyses. Sixty per cent of the patients were willing to inform their relatives about familial diabetes risk; 61% reported high family risk perception and 41% had positive control beliefs with regard to preventive options in relatives. A majority (69%) did not express serious concern about relatives developing diabetes. Worry about relatives, knowing what to tell, whom to notify, and communication about diabetes in general appeared to facilitate family risk disclosure. Unexpectedly, high family risk perception in itself did not significantly increase patients' intentions to inform relatives; rather, risk perception appeared to exert an indirect effect through worry and beliefs about diabetes prevention. Worry in patients with diabetes appears to be a key factor in the process of family risk disclosure. When professionals guide their patients in this process, they should not only provide risk information, but also address worries and emphasize opportunities for diabetes prevention. © 2012 The Authors.

Dickmann, Petra; Apfel, Franklin; Biedenkopf, Nadine; Eickmann, Markus; Becker, Stephan

2015-01-01

Current risk assessment and risk communication of biosafety and biosecurity concerns lack a convenient metric and conceptual framework. The absence of such a systematic tool makes communication more difficult and can lead to ambiguous public perception of and response to laboratory biosafety incidents and biosecurity threats. A new 7-category scoring scale is proposed for incidents and situations in laboratories related to the handling of human and animal pathogens. The scale aims to help clarify risk categories, facilitate coordination and communication, and improve public understanding of risk related to biosafety and biosecurity.

Family Presence During Resuscitation: Physicians' Perceptions of Risk, Benefit, and Self-Confidence.

PubMed

Twibell, Renee Samples; Siela, Debra; Neal, Alexis; Riwitis, Cheryl; Beane, Heather

Families often desire proximity to loved ones during life-threatening resuscitations and perceive clear benefits to being present. However, critical care nurses and physicians perceive risks and benefits. Whereas research is accumulating on nurses' perceptions of family presence, physicians' perspectives have not been clearly explicated. Psychometrically sound measures of physicians' perceptions are needed to create new knowledge and enhance collaboration among critical care nurses and physicians during resuscitation events. This study tests 2 new instruments that measure physicians' perceived risks, benefits, and self-confidence related to family presence during resuscitation. By a correlational design, a convenience sample of physicians (N = 195) from diverse clinical specialties in 1 hospital in the United States completed the Physicians' Family Presence Risk-Benefit Scale and Physicians' Family Presence Self-confidence Scale. Findings supported the internal consistency reliability and construct validity of both new scales. Mean scale scores indicated that physicians perceived more risk than benefit and were confident in managing resuscitations with families present, although more than two-thirds reported feeling anxious. Higher self-confidence was significantly related to more perceived benefit and less perceived risk (P = .001). Younger physicians, family practice physicians, and physicians who previously had invited family presence expressed more positive perceptions (P = .05-.001). These 2 new scales offer a means to assess key perceptions of physicians related to family presence. Further testing in diverse physician populations may further validate the scales and yield knowledge that can strengthen collaboration among critical care nurses and physicians and improve patient and family outcomes.

"Missing pieces": exploring cardiac risk perceptions in older women.

Approximately 95% of older women have factors that put them at risk for developing cardiovascular disease, but research indicates many do not perceive themselves to be at risk. We examined older women's perceived risk for coronary heart disease (CHD) and the factors influencing their perceptions. We conducted a descriptive, qualitative study using in-depth, individual interviews and quantitative measures to assess perceived risk and risk factors. Twenty-four older African American and Caucasian women had a mean 4.46 cardiac risk factors but perceived their own CHD risk as unrealistically low at 1.95 cm (SD = 1.57, on 0-to-8 cm visual analogue scale). Narrative data clustered in themes that represented a lack of fact-based information and multiple misconceptions about CHD and prevention. Major improvements in CHD health are only achievable if risk factors are prevented. This research suggests older women have substantial needs for consistent CHD information and prevention guidance.

2000-01-01

Understanding the high-risk adolescent's perception of risk taking is essential for health professionals to determine appropriate interventions. The purpose of this study was to examine the psychometric properties of the revised Adolescent Risk-Taking Instrument (ARTI) designed to measure the high-risk adolescent's perception of risk taking. This study also examined the variables that are most predictive of social adaptation and risk taking. An ex post facto design was used to standardize data collection and to assess the psychometric properties of the revised ARTI. The nonprobability sample consisted of 167 adolescents attending school in an urban, health-underserved area. Exploratory factor analysis supported construct validity, and Chronbach's Coefficient Alpha supported internal consistency reliability. The reliability coefficient for the risk taking and social adaptation constructs were .80 and .77, respectively. Current perspectives on adolescent risk taking and implications for the use of the ARTI in clinical practice are addressed.

Objective Emotion plays a strong role in the perception of risk information but is frequently underemphasized in the decision-making and communication literature. We sought to discuss and put into context several lines of research that have explored the links between emotion and risk perceptions, Methods In this article, we provide a focused, “state of the science” review of research revealing the ways that emotion, or affect, influences people’s cancer-related decisions. We identify illustrative experimental research studies that demonstrate the role of affect in people’s estimates of cancer risk, their decisions between different cancer treatments, their perceptions of the chance of cancer recurrence, and their reactions to different methods of presenting risk information. Results These studies show that people have strong affective reactions to cancer risk information and that the way risk information is presented often determines the emotional gist people take away from such communications. Conclusion Cancer researchers, educators and oncologists need to be aware that emotions are often more influential in decision making about cancer treatments and prevention behaviors than factual knowledge is.

GM foods and the misperception of risk perception.

2004-02-01

Public opposition to genetically modified (GM) food and crops is widely interpreted as the result of the public's misperception of the risks. With scientific assessment pointing to no unique risks from GM crops and foods, a strategy of accurate risk communication from trusted sources has been advocated. This is based on the assumption that the benefits of GM crops and foods are self-evident. Informed by the interpretation of some qualitative interviews with lay people, we use data from the Eurobarometer survey on biotechnology to explore the hypothesis that it is not so much the perception of risks as the absence of benefits that is the basis of the widespread rejection of GM foods and crops by the European public. Some respondents perceive both risks and benefits, and may be trading off these attributes along the lines of a rational choice model. However, for others, one attribute-benefit-appears to dominate their judgments: the lexicographic heuristic. For these respondents, their perception of risk is of limited importance in the formation of attitudes toward GM food and crops. The implication is that the absence of perceived benefits from GM foods and crops calls into question the relevance of risk communication strategies for bringing about change in public opinion.

Expert risk perceptions and the social amplification of risk: A case study in invasive tree pests and diseases.

2017-11-01

The Social Amplification of Risk Framework (SARF) is often used as a conceptual tool for studying diverse risk perceptions associated with environmental hazards. While widely applied, it has been criticised for implying that it is possible to define a benchmark 'real' risk that is determined by experts and around which public risk perceptions can subsequently become amplified. It has been argued that this objectification of risk is particularly problematic when there are high levels of scientific uncertainty and a lack of expert consensus about the nature of a risk and its impacts. In order to explore this further, this paper examines how 'experts' - defined in this case as scientists, policy makers, outbreak managers and key stakeholders - construct and assemble their understanding of the risks associated with two invasive tree pest and disease outbreaks in the UK, ash dieback and oak processionary moth. Through semi-structured interviews with experts in each of the case study outbreaks, the paper aims to better understand the nature of information sources drawn on to construct perceptions of tree health risks, especially when uncertainty is prevalent. A key conclusion is that risk assessment is a socially-mediated, relational and incremental process with experts drawing on a range of official, anecdotal and experiential sources of information, as well as reference to past events in order to assemble the risk case. Aligned with this, experts make attributions about public concern, especially when the evidence base is incomplete and there is a need to justify policy and management actions and safeguard reputation.

Perceptions of risk, risk aversion, and barriers to adoption of decision support systems and integrated pest management: an introduction.

Rational management of plant diseases, both economically and environmentally, involves assessing risks and the costs associated with both correct and incorrect tactical management decisions to determine when control measures are warranted. Decision support systems can help to inform users of plant disease risk and thus assist in accurately targeting events critical for management. However, in many instances adoption of these systems for use in routine disease management has been perceived as slow. The under-utilization of some decision support systems is likely due to both technical and perception constraints that have not been addressed adequately during development and implementation phases. Growers' perceptions of risk and their aversion to these perceived risks can be reasons for the "slow" uptake of decision support systems and, more broadly, integrated pest management (IPM). Decision theory provides some tools that may assist in quantifying and incorporating subjective and/or measured probabilities of disease occurrence or crop loss into decision support systems. Incorporation of subjective probabilities into IPM recommendations may be one means to reduce grower uncertainty and improve trust of these systems because management recommendations could be explicitly informed by growers' perceptions of risk and economic utility. Ultimately though, we suggest that an appropriate measure of the value and impact of decision support systems is grower education that enables more skillful and informed management decisions independent of consultation of the support tool outputs.

Studies that integrate human dimensions and the biophysical characteristics of watersheds are necessary to meet the challenge of sustainable water resources development. In this project, we integrated perspectives from sociology, hydrology, and environmental engineering to examine and suggest solutions for managing waterborne disease risks associated with wastewater contamination in the Sonora River basin (SRB), a semiarid rural basin in northwest Mexico. This research consisted of four sub-projects. First, we assessed the perceptions of risks associated with wastewater contamination of water resources in rural communities in the SRB through a series of semi-structured interviews Results from this study indicate that there are major differences in risk perceptions among health professionals, government officials, and lay citizens. Government officials and lay citizens tend to underestimate the severity of the problems related to water related risks. Second, a fully distributed hydrologic model was used to make streamflow predictions in the un-gauged SRB. Synthetic flows generated from the hydrologic model were used to evaluate pollutant transport processes associated with wastewater loadings to the Sonora River. The hydrologic model revealed that the high degree of spatio-temporal variability of runoff in the SRB is associated with links between runoff generation mechanisms and land-atmosphere interactions. Third, a surface water quality model was used to assess the impact of wastewater discharges and develop pathogen contamination indicators in two sites along the Sonora River. To parameterize the water quality model, pathogenic indicator loadings and removal rates were estimated, along with their uncertainty. Results from the water quality modeling show regions in the watershed that may be exceeding pathogenic standards, but also that uncertainty in model parameters requires a probabilistic approach for estimating risks. Finally, a workshop was conducted to explore the use of participatory modeling frameworks in less developed regions. Results indicate that respondents agreed strongly with the hydrologic and water quality modeling methodologies presented and considered the modeling results useful. Our results also show that participatory modeling approaches can have short term impacts as seen in the changes in water-related risk perceptions. In total, these projects revealed that water resources management solutions need to take into account variations across the human landscape (i.e. risk perceptions) and variations in the biophysical response of watersheds to natural phenomena (i.e. streamflow generation) and to anthropogenic activities (i.e. contaminant fate and transport). In addition, this work underscores the notion that sustainable water resources solutions need to contend with uncertainty in our understanding and predictions of human perceptions and biophysical systems.

Despite the high efficacy of tuberculosis (TB) drug regiments, one of the barriers in the TB control program is the non-compliance to treatment. Morbidity, mortality, and risk to become resistant to drugs are emerging among defaulters. Thus, the aim of this study is to identify the factors, especially knowledge and perceptions of TB and association with treatment default among patients treated in primary care settings, East Nusa Tenggara. This study was part of a bigger cohort community-based controlled trial study. The subjects were newly diagnosed pulmonary TB patients from four districts in East Nusa Tenggara. Knowledge, perception of TB, and other related factors were assessed prior to the treatment. Patients who interrupted the treatment in two consecutive months were classified as defaulters, as World Health Organization stated. Odds ratio (OR) looking for factors associated with becoming defaulter was analyzed. A total of 300 patients were recruited for this study. At the end of the treatment, 255 patients (85%) completed the treatment without interruption from regular visit. In univariate analysis, none of the socio-demographic factors attributed to treatment default yet lack of knowledge and incorrect perception of TB prior therapy (OR 2.49 1.30-4.79 95% CI, p = 0.006; OR 5.40 2.64-11.04 95% CI, p < 0.001, respectively). In multivariate analysis, only incorrect perception of TB showed significant association with treatment default (OR 4.75 2.30-9.86 95% CI). Assessing the knowledge and perception of TB prior to the treatment in newly pulmonary TB patients is important as both of them were known as risk factor for treatment default. Education and counseling may be required to improve patients' compliance to treatment.

[Evidence of work-related musculo-skeletal disorders of the upper extremities and current methods of risk assessment: can Charlie Chaplin give us any suggestions in "modern times"].

in some sequences of the film "Modern Times" Chaplin is clearly involved in activities at high risk for work-related musculo-skeletal disorders of the upper extremities (UEWMSDs), but evidence and perception of any complaint are not evident. To evaluate the extent of the biomechanical risk using current risk assessment methods and discuss the possible reasons for lack of complaints. we made an analysis using six of the current methods for ergonomic risk assessment (State of Washington, check list OCRA, HAL by ACGIH, RULA Strain Index, OREGE). All the methods applied demonstrated high-to-very high levels of biomechanical risk for the upper extremities, with evident psychic effects but without apparent musculo-skeletal disorders. The discrepancy between evident psychological disorders ad apparent absence of UEWMSDs are discussed as being due to either: an artistic choice by Charlie Chaplin who focused on the aspects thought to be more immediately and easily comic; the short duration of the physical load exertion; or because of a different perception of muscular work and fatigue that was also typical until the 1970's and 1980's, which also confirmed the principles and practices of our preventive and medical disciplines at that time.

MacGregor, D.G.; Slovic, P.; Morgan, M.G.

Potential health risks from exposure to power-frequency electromagnetic fields (EMF) have become an issue of significant public concern. This study evaluates a brochure designed to communicate EMF health risks from a scientific perspective. The study utilized a pretest-posttest design in which respondents judged various sources of EMF (and other) health and safety risks, both before reaching the brochure and after. Respondents assessed risks on dimensions similar to those utilized in previous studies of risk perception. In addition, detailed ratings were made that probed respondents' beliefs about the possible causal effects of EMF exposure. The findings suggest that naive beliefs aboutmore » the potential of EMF exposure to cause harm were highly influenced by specific content elements of the brochure. The implications for using risk-communication approaches based on communicating scientific uncertainty are discussed. 19 refs., 1 fig., 11 tabs.« less

Framing risk in pandemic influenza policy and control.

PubMed

Seetoh, Theresa; Liverani, Marco; Coker, Richard

2012-01-01

This article explores differing understandings of 'risk' in relation to pandemic influenza policy and control. After a preliminary overview of methodological and practical problems in risk analysis, ways in which risk was framed and managed in three historical cases were examined. The interdependence between scientific empiricism and political decision-making led to the mismanagement of the 1976 swine influenza scare in the USA. The 2004 H5N1 avian influenza outbreak in Thailand, on the other hand, was undermined by questions of national economic interest and concerns over global health security. Finally, the recent global emergency of pandemic influenza H1N1 in 2009 demonstrated the difficulties of risk management under a context of pre-established perceptions about the characteristics and inevitability of a pandemic. Following the analysis of these cases, a conceptual framework is presented to illustrate ways in which changing relationships between risk assessment, risk perception and risk management can result in differing policy strategies.

Many models exist to estimate a woman's risk of development of breast cancer. At screening mammography, many imaging centers collect data required for these models to identify women who may benefit from supplemental screening and referral for cancer risk assessment. The purpose of this study was to discern perceptions and preferences of screening mammography patients regarding communication of estimated breast cancer risk. An anonymous survey was distributed to screening and surveillance mammography patients between April and June 2015. Survey questions were designed to assess patient preferences regarding the receipt and complexity of risk estimate communication, including hypothetical scenarios with and without > 20% estimated risk of breast cancer. The McNemar test and the Wilcoxon signed rank test were used with p ≤ 0.05 considered statistically significant. The survey was distributed to 1061 screening and surveillance mammography patients, and 503 patients responded (response rate, 47%). Although 86% (431/503) of patients expressed interest in learning their estimated risk, only 8% (38/503) had undergone formal risk assessment. The preferred method (241 respondents [26%]) of communication of risk < 20% was a mailed letter accompanying annual mammogram results. For risk > 20%, patients preferred oral communication and were 10-fold as likely to choose only oral communication (p < 0.000001). For risk < 20% and > 20%, patients preferred to learn their estimated risk in great detail (69% and 85%), although women were significantly more likely to choose greater detail for risk > 20% (p < 0.00001). Screening mammography patients expressed interest in learning their estimated risk of breast cancer regardless of their level of hypothetical risk.

Risk attitudes and personality traits predict perceptions of benefits and risks for medicinal products: a field study of European medical assessors.

PubMed

Beyer, Andrea R; Fasolo, Barbara; de Graeff, P A; Hillege, H L

2015-01-01

Risk attitudes and personality traits are known predictors of decision making among laypersons, but very little is known of their influence among experts participating in organizational decision making. Seventy-five European medical assessors were assessed in a field study using the Domain Specific Risk Taking scale and the Big Five Inventory scale. Assessors rated the risks and benefits for a mock "clinical dossier" specific to their area of expertise, and ordinal regression models were used to assess the odds of risk attitude or personality traits in predicting either the benefit or the risk ratings. An increase in the "conscientiousness" score predicted an increase in the perception of the drug's benefit, and male assessors gave higher scores for the drug's benefit ratings than did female assessors. Extraverted assessors saw fewer risks, and assessors with a perceived neutral-averse or averse risk profile saw greater risks. Medical assessors perceive the benefits and risks of medicines via a complex interplay of the medical situation, their personality traits and even their gender. Further research in this area is needed to determine how these potential biases are managed within the regulatory setting.

The precautionary principle and/or risk assessment in World Trade Organization decisions: a possible role for risk perception.

PubMed

Goldstein, Bernard; Carruth, Russellyn S

2004-04-01

Risk analysis has been recognized and validated in World Trade Organization (WTO) decision processes. In recent years the precautionary principle has been proposed as an additional or alternative approach to standard risk assessment. The precautionary principle has also been advocated by some who see it as part of postmodern democracy in which more power is given to the public on health and safety matters relative to the judgments of technocrats. A more cynical view is that the precautionary principle is particularly championed by the European Community as a means to erect trade barriers. The WTO ruling against the European Community's trade barrier against beef from hormone-treated cattle seemed to support the use of risk assessment and appeared to reject the argument that the precautionary principle was a legitimate basis for trade barriers. However, a more recent WTO decision on asbestos contains language suggesting that the precautionary principle, in the form of taking into account public perception, may be acceptable as a basis for a trade barrier. This decision, if followed in future WTO trade disputes, such as for genetically modified foods, raises many issues central to the field of risk analysis. It is too early to tell whether the precautionary principle will become accepted in WTO decisions, either as a supplement or a substitute for standard risk assessment. But it would undermine the value of the precautionary principle if this principle were misused to justify unwarranted trade barriers.

Heuristics structure and pervade formal risk assessment.

PubMed

MacGillivray, Brian H

2014-04-01

Lay perceptions of risk appear rooted more in heuristics than in reason. A major concern of the risk regulation literature is that such "error-strewn" perceptions may be replicated in policy, as governments respond to the (mis)fears of the citizenry. This has led many to advocate a relatively technocratic approach to regulating risk, characterized by high reliance on formal risk and cost-benefit analysis. However, through two studies of chemicals regulation, we show that the formal assessment of risk is pervaded by its own set of heuristics. These include rules to categorize potential threats, define what constitutes valid data, guide causal inference, and to select and apply formal models. Some of these heuristics lay claim to theoretical or empirical justifications, others are more back-of-the-envelope calculations, while still more purport not to reflect some truth but simply to constrain discretion or perform a desk-clearing function. These heuristics can be understood as a way of authenticating or formalizing risk assessment as a scientific practice, representing a series of rules for bounding problems, collecting data, and interpreting evidence (a methodology). Heuristics are indispensable elements of induction. And so they are not problematic per se, but they can become so when treated as laws rather than as contingent and provisional rules. Pitfalls include the potential for systematic error, masking uncertainties, strategic manipulation, and entrenchment. Our central claim is that by studying the rules of risk assessment qua rules, we develop a novel representation of the methods, conventions, and biases of the prior art. © 2013 Society for Risk Analysis.

Radiation effects and risks: overview and a new risk perception index.

PubMed

Rehani, M M

2015-07-01

Uncertainty provides opportunities for differences in perception, and radiation risks at low level of exposures involved in few computed tomography scans fall in this category. While there is good agreement among national and international organisations on risk probability of cancer, risk perception has barely been dealt with by these organisations. Risk perception is commonly defined as the subjective judgment that people make about the characteristics and severity of a risk. Severity and latency are important factors in perception. There is a need to connect all these. Leaving risk perception purely as a subjective judgement provides opportunities for people to amplifying risk. The author postulates a risk perception index as severity divided by latency that becomes determining factor for risk perception. It is hoped that this index will bring rationality in risk perception. © The Author 2015. Published by Oxford University Press. All rights reserved.

Mothers of children with food allergy have increased anxiety, which may be influenced by healthcare professionals' communication of risk. To evaluate a brief psychological intervention for reducing anxiety in mothers of children with food allergy. Two hundred mothers of children with food allergy were recruited from allergy clinics. A computer-generated randomization list was used to allocate participants to a single-session cognitive behavioural therapy intervention including a risk communication module, or standard care. Anxiety and risk perception were assessed at 6 weeks and 1 year. Primary outcome was state anxiety at 6 weeks. Secondary outcomes included state anxiety at 1 year, risk perception at 6 weeks and 1 year, and salivary cortisol response to a simulated anaphylaxis scenario at 1 year. We found no significant difference in the primary outcome state anxiety at 6 weeks, with mean 31.9 (SD 10.2) intervention, 34.0 (10.2) control; mean difference 2.1 (95% CI -0.9, 5.0; P=.17). There was significantly reduced state anxiety at 6 weeks in the intervention group, in the subgroup of participants with moderate/high anxiety at enrolment (103/200, 52%), with mean 33.0 (SD 9.3) intervention, 37.8 (SD 10.0) control; mean difference 4.8 (95% CI 0.9, 8.7; P=.016; Cohen's d effect size 0.50). The psychological intervention also reduced risk perception and salivary cortisol response (P=.032; effect size 0.36). We found evidence that a brief psychological intervention which incorporates accurate risk information may impact on anxiety, risk perception and physiological stress response in mothers of children with food allergy. © 2017 John Wiley & Sons Ltd.

Healthcare professionals' (HCPs') perception of risk associated with drug use in pregnancy may have an impact on the pharmacological treatment of some women. The aim of this study was to examine this risk perception in a sample of Swiss HCPs with a special focus on their knowledge and use of available specialised information sources. An online, French and German, questionnaire was e-mailed to 7,136 members of four Swiss professional societies (gynaecologists, paediatricians, midwives and pharmacists). The questionnaire was designed (a) to collect demographic characteristics, (b) to evaluate the frequency of use of several specialised sources of information on drugs in pregnancy in their daily practice, and (c) to examine the perception of risk associated with drug use during pregnancy. A total of 1,310 questionnaires were collected (response rate of 18.4%). More than 80% of the respondent HCPs use the Swiss Drug Reference Book (Compendium) to assess the risk associated with drugs during pregnancy and are not aware of available specialised information sources (books, websites or information centres). Despite some disparities between HPCs, the risk related to drug intake was overall highly misperceived. Blinded reading of three product monographs in the Compendium was associated with an overestimated perception of risk (e.g., after reading the "paracetamol" monograph, 38% of the participants stated they would probably not advise the use of this drug to a pregnant patient). Overall, an overestimation of the risk associated with drug use during pregnancy has been observed in our sample of HCPs, which might be related to the underuse of specialised information source among other factors. These findings evidenced the need for increased training for HCPs in order to optimise medication use during pregnancy. Further studies are needed to confirm these results and identify causes.

The present study analyzed people's risk perception regarding driving a car with studded or non-studded winter tires. Subjects were 252 residents of Sapporo, where a recent municipal ordinance prohibited studded tires, allowing only non-studded ones. Questionnaire data were examined concerning (1) the relationship between risk perception and its acceptance, (2) the effect of an inserted message, which was either positive or negative about the use of non-studded tires, and (3) the role of personal involvement, assessed with Personal Involvement Inventory (Zaichkowsky, 1985), regarding winter driving. Results were as follows: (1) The use of non-studded tires was favorably judged because of social benefit, but subjects hesitated to choose them because of a higher perceived possibility of an accident. (2) The inserted message had significant effects on benefit evaluation and perceived accident possibility. The effects were weaker for drivers who had experienced driving a car with studded tires. And (3) personal involvement had a weak correlation with risk judgements of the present study.

In the recent past, the mining industry has witnessed a substantial increase in the numbers of fatalities occurring at metal and nonmetal mine sites, but it is unclear why this is occurring. One possible explanation is that workers struggle with identifying worksite hazards and accurately assessing the associated risk. The purpose of this research was to explore this possibility within the mining industry and to more fully understand stone, sand and gravel (SSG) mine workers' thoughts, understandings and perceptions of worksite hazards and risks. Eight mine workers were interviewed and asked to identify common hazards they come across when doing their jobs and to then discuss their perceptions of the risks associated with those identified hazards. The results of this exploratory study indicate the importance of workers' job-related experience as it applies to hazard identification and risk perception, particularly their knowledge of or familiarity with a task, whether or not they had personal control over that task, and the frequency with which they perform that task.

Objective To determine whether providing corrective health information can reduce the tendency of consumers to believe that the implied marketing message that two “potentially reduced exposure products” (PREPs) are safer than regular cigarettes. Design Face‐to‐face interviews with smokers assigned to one of four conditions, which varied in terms of the presence or absence of health information that qualified claims made in advertising for two PREPs. Subjects A convenience sample of 177 smokers in Boston area. Interventions Health information detailed the extent to which exposure to toxins and health risks of the brands were unknown. Main outcome measures Respondents' assessments of the health risks and toxicity of the two combustible PREPs, Advance and Eclipse. Results The health information had a modest but significant effect on ratings of health risk, and reduced perceptions that switching to the new brands would lower a smoker's risk of cancer (OR 0.75; p<0.05). The health information had no effect on perceptions of toxicity. Conclusions A small dose of corrective information was effective in tempering smokers' perceptions. A higher dose of public health campaigns would be needed to affect misperceptions likely to follow a full‐scale tobacco marketing effort. PMID:17897988

The exposure of pregnant women to environmental contaminants is a subject of international concern. However, the risk perception of these contaminants by health professionals (HP) has not been extensively investigated. The main objective of the PERI-HELPE study (Perception of Risk-HEaLth Professionals & Environment Study) was to assess the risk perception of environmental exposure of pregnant women by perinatal HPs. The secondary objectives were to describe the preventive attitudes of perinatal HPs concerning chemicals exposure of pregnant women and to identify the barriers to preventive attitude. A cross-sectional study was performed in 2015 in France. One hundred eighty-nine HPs (obstetricians, midwives, and general practitioners) replied to an online self-administered questionnaire (participation rate: 11%). Carbon monoxide, pesticides and lead were the contaminants most frequently perceived as a high risk for pregnant women. A minority of HPs asked women about their chemical exposure and advised them to reduce exposure. The lack of information, training and scientific evidence in environmental health were the main difficulties declared by the HPs to advise pregnant women. Despite the low response rate, our findings provide important information to encourage French health authorities to take into account the difficulties encountered by HPs and set up appropriate training programs in Environmental health.

Millions of low-income people of diverse ethnicities inhabit stressful old urban industrial neighborhoods. Yet we know little about the health impacts of built-environment stressors and risk perceptions in such settings; we lack even basic health profiles. Difficult access is one reason (it took us 30 months to survey 80 households); the lack of multifaceted survey tools is another. We designed and implemented a pilot vulnerability assessment tool in Worcester, Massachusetts. We answer: (1) How can we assess vulnerability to multiple stressors? (2) What is the nature of complex vulnerability-including risk perceptions and health profiles? (3) How can findings be used by our wider community, and what lessons did we learn? (4) What implications arise for science and policy? We sought a holistic picture of neighborhood life. A reasonably representative sample of 80 respondents captured data for 254 people about: demographics, community concerns and resources, time-activity patterns, health information, risk/stress perceptions, and resources/capacities for coping. Our key findings derive partly from the survey data and partly from our experience in obtaining those data. Data strongly suggest complex vulnerability dominated by psychosocial stress. Unexpected significant gender and ethnic disease disparities emerged: notably, females have twice the disease burden of males, and white females twice the burden of females of color (p < 0.01). Self-reported depression differentiated by gender and age is illustrative. Community based participatory research (CBPR) approaches require active engagement with marginalized populations, including representatives as funded partners. Complex vulnerability necessitates holistic, participatory approaches to improve scientific understanding and societal responses. © 2010 Society for Risk Analysis.

Global motion perception is often used as an index of dorsal visual stream function in neurodevelopmental studies. However, the relationship between global motion perception and visuomotor control, a primary function of the dorsal stream, is unclear. We measured global motion perception (motion coherence threshold; MCT) and performance on standardized measures of motor function in 606 4.5-year-old children born at risk of abnormal neurodevelopment. Visual acuity, stereoacuity and verbal IQ were also assessed. After adjustment for verbal IQ or both visual acuity and stereoacuity, MCT was modestly, but significantly, associated with all components of motor function with the exception of fine motor scores. In a separate analysis, stereoacuity, but not visual acuity, was significantly associated with both gross and fine motor scores. These results indicate that the development of motion perception and stereoacuity are associated with motor function in pre-school children. Copyright © 2017 Elsevier Ltd. All rights reserved.

Development of a survey to assess adolescent perceptions of teen parenting.

Herrman, Judith W; Nandakumar, Ratna

2012-01-01

Initiatives designed to prevent teen pregnancy are often based on adult perceptions of the negative aspects of a teen birth. Qualitative research has revealed that teens may perceive positive rewards associated with teen parenting. These perceptions have not yet been examined through survey research. The theory of reasoned action proposes that individuals assess the costs and rewards prior to engaging in a behavior and provides a framework for the development of a survey instrument designed to measure adolescent thoughts about the costs and rewards of the teen parenting experience. This manuscript describes the development and testing of a quantitative survey instrument designed to measure adolescents' perceptions. Pretesting, piloting, exploratory factor analysis, and a variety of reliability and validity measures were used to determine the value of the measure. The thoughts on teen parenting survey (TTPS) demonstrates an alpha level of .90. The TTPS yields a cumulative score of teen perceptions about the impact of a teen birth during the adolescent years that may be used to assess youth beliefs, correlated with demographic data, used to identify teens at risk for pregnancy/parenting, or provide a pretest/posttest to assess the effectiveness of interventions designed to foster realistic attitudes toward teen parenting.

When the facts are just not enough: credibly communicating about risk is riskier when emotions run high and time is short.

When discussing risk with people, commonly subject matter experts believe that conveying the facts will be enough to allow people to assess a risk and respond rationally to that risk. Because of this expectation, experts often become exasperated by the seemingly illogical way people assess personal risk and choose to manage that risk. In crisis situations when the risk information is less defined and choices must be made within impossible time constraints, the thought processes may be even more susceptible to faulty heuristics. Understanding the perception of risk is essential to understanding why the public becomes more or less upset by events. This article explores the psychological underpinnings of risk assessment within emotionally laden events and the risk communication practices that may facilitate subject matter experts to provide the facts in a manner so they can be more certain those facts are being heard. Source credibility is foundational to risk communication practices. The public meeting is one example in which these best practices can be exercised. Risks are risky because risk perceptions differ and the psychosocial environment in which risk is discussed complicates making risk decisions. Experts who want to influence the actions of the public related to a threat or risk should understand that decisions often involve emotional as well as logical components. The media and other social entities will also influence the risk context. The Center for Disease Control and Prevention's crisis and emergency-risk communication (CERC) principles are intended to increase credibility and recognize emotional components of an event. During a risk event, CERC works to calm emotions and increase trust which can help people apply the expertise being offered by response officials. Copyright © 2011. Published by Elsevier Inc.

2012-12-01

The Food and Drug Administration (FDA) issued new organ-specific warning label requirements for over-the-counter (OTC) analgesic products in order to make consumers aware of the risk of liver damage when using acetaminophen. However, awareness of a health risk alone cannot ensure consumers' engagement in safe and preventive behaviour. In this study, we attempted to: (i) measure consumer risk perception of liver damage due to the OTC acetaminophen products and (ii) analyse the effectiveness of the new organ-specific warning label in improving consumer risk perception of liver damage and intention to perform protective behaviours while using OTC acetaminophen products. This within-subject experimental study used a convenience sample of English-speaking adults visiting OTC segments of selected pharmacy stores in Houston. Participants were randomly exposed to the old and new warning labels and their respective risk perception (measured on a visual analogue scale, 0%, no risk, to 100%, extreme risk) and behavioural intention (measured on a 7-point Likert scale) were recorded using a validated, self-administered questionnaire. Descriptive statistics and non-parametric Wilcoxon signed-rank tests were performed using sas statistical software (v 9.2) at a priori significance level of 0.05. Majority of participants (74.4%) were not aware of the new warnings; however, majority (67.8%) had prior knowledge of the risk. The mean risk perception score for the new warning label was found to be significantly higher (72.2% vs. 65.9%, P < 0.0001) than the old warning label. Similarly, the average intention score for the new warning label was significantly higher (5.06 vs. 4.86, P < 0.0001) than the old warning label. The new warning label mandated by FDA is effective in improving consumer risk perception of potential liver damage and may encourage protective behaviour. However, future studies are essential to assess the impact of the new label on actual changes in consumer behaviour and subsequent reduction in acetaminophen-related morbidity and mortality. © 2012 Blackwell Publishing Ltd.

herpes simplex virus type 2 (HSV-2) and human papillomavirus (HPV) are the most frequent sexually transmitted infections (STI) among college students 18-24 years old. Educational interventions for STI prevention can help to decrease viral STI prevalence among students. to know the change in knowledge, perception of risk and sexual behavior among 182 students of the Autonomous University of the State of Morelos. a community intervention trial (before-after) was carried out, using brochures for prevention of HSV-2 and HPV, including information about these STI, with emphasis on the risk factors identified in students of the same university. we found a change in the perception of STI risk during the intervention (56.5 before vs. 67.7% after intervention), possibly the brochures assisted students to learn more about their own risk behaviors. Likewise, there was an increase in knowledge in both HPV and HSV-2. it is necessary to increase the sample size in future interventions to assess further the change in knowledge, sexual behaviors and the prevalence of infections.

This study aimed to better understand the current situation of risk assessment and identify the factors associated with competence of emergency responders in public health risk assessment. The participants were selected by a multi-stage, stratified cluster sampling method in Heilongjiang Centers for Disease Control and Prevention (CDC). The questionnaires that measured their perceptions on risk assessment competences were administered through the face-to-face survey. A final sample of 1889 staff was obtained. Of this sample, 78.6% of respondents rated their own risk assessment competences as "relatively low", contrasting with 21.4% rated as "relatively high". Most of the respondents (62.7%) did not participate in any risk assessment work. Only 13.7% and 42.7% of respondents reported participating in risk assessment training and were familiar with risk assessment tools. There existed statistical significance between risk assessment-related characteristics of respondents and their self-rated competences scores. Financial support from the government and administrative attention were regarded as the important factors contributing to risk assessment competences of CDC responders. Higher attention should be given to risk assessment training and enhancing the availability of surveillance data. Continuous efforts should be made to remove the financial and technical obstacles to improve the competences of risk assessment for public health emergency responders.

Predation Risk Perception, Food Density and Conspecific Cues Shape Foraging Decisions in a Tropical Lizard

PubMed Central

Kolbe, Jason J.

2015-01-01

When foraging, animals can maximize their fitness if they are able to tailor their foraging decisions to current environmental conditions. When making foraging decisions, individuals need to assess the benefits of foraging while accounting for the potential risks of being captured by a predator. However, whether and how different factors interact to shape these decisions is not yet well understood, especially in individual foragers. Here we present a standardized set of manipulative field experiments in the form of foraging assays in the tropical lizard Anolis cristatellus in Puerto Rico. We presented male lizards with foraging opportunities to test how the presence of conspecifics, predation-risk perception, the abundance of food, and interactions among these factors determines the outcome of foraging decisions. In Experiment 1, anoles foraged faster when food was scarce and other conspecifics were present near the feeding tray, while they took longer to feed when food was abundant and when no conspecifics were present. These results suggest that foraging decisions in anoles are the result of a complex process in which individuals assess predation risk by using information from conspecific individuals while taking into account food abundance. In Experiment 2, a simulated increase in predation risk (i.e., distance to the feeding tray) confirmed the relevance of risk perception by showing that the use of available perches is strongly correlated with the latency to feed. We found Puerto Rican crested anoles integrate instantaneous ecological information about food abundance, conspecific activity and predation risk, and adjust their foraging behavior accordingly.

2015-01-01

With over half of individuals incarcerated having serious mental health concerns, correctional settings offer excellent opportunities for epidemiological, prevention, and intervention research. However, due to unique ethical and structural challenges, these settings create risks and vulnerabilities for participants not typically encountered in research populations. We surveyed 1,224 researchers, IRB members, and IRB prisoner representatives to assess their perceptions of risks associated with mental health research conducted in correctional settings. Highest-ranked risks were related to privacy, stigma, and confidentiality; lowest-ranked risks were related to prisoners’ loss of privileges or becoming targets of violence due to having participated in research. Cognitive impairment, mental illness, lack of autonomy, and limited access to services emerged as the greatest sources of vulnerability; being male, being female, being over age of 60, being a minority, and being pregnant were the lowest-ranked sources of vulnerability. Researchers with corrections experience perceived lower risks and vulnerabilities than all other groups, raising the question whether these researchers accurately appraise risk and vulnerability based on experience, or if their lower risk and vulnerability perceptions reflect potential bias due to their vested interests. By identifying areas of particular risk and vulnerability, this study provides important information for researchers and research reviewers alike. PMID:27092025

How Fear-Arousing News Messages Affect Risk Perceptions and Intention to Talk About Risk.

Paek, Hye-Jin; Oh, Sang-Hwa; Hove, Thomas

2016-09-01

Building on the theoretical arguments of the impersonal-impact and differential-impact hypotheses, this study has a twofold purpose: first, to demonstrate how fear-arousing media messages about risk are associated with personal-level risk perception, as well as, and perhaps more so than, societal-level risk perception; and second, to examine how the resulting risk perceptions can mediate intention to talk about the risk with family and friends. A news message evaluation study was conducted among the general public in South Korea concerning two major risks, carcinogens and bovine spongiform encephalopathy (BSE). Two sets of structural equation models reveal three main findings: (a) Fear-arousing news messages are positively related to personal-level risk perception, as well as to societal-level risk perception; (b) fear-arousing news messages result in intention to talk about the risk directly and indirectly through risk perception; and (c) personal-level risk perception appears more strongly related to intention to talk than does societal-level risk perception, although such relationships may vary across risk topics.

Industrial air pollution in rural Kenya: community awareness, risk perception and associations between risk variables

PubMed Central

2014-01-01

Background Developing countries have limited air quality management systems due to inadequate legislation and lack of political will, among other challenges. Maintaining a balance between economic development and sustainable environment is a challenge, hence investments in pollution prevention technologies get sidelined in favor of short-term benefits from increased production and job creation. This lack of air quality management capability translates into lack of air pollution data, hence the false belief that there is no problem. The objectives of the study were to: assess the population’s environmental awareness, explore their perception of pollution threat to their health; examine the association between specific health hazards. Methods A cross-sectional study was implemented by gathering quantitative information on demographic, health status, environmental perception and environmental knowledge of residents to understand their view of pollution in their neighborhood. Focus group discussions (FGDs) allowed for corroboration of the quantitative data. Results Over 80% of respondents perceived industrial pollution as posing a considerable risk to them despite the fact that the economy of the area largely depended on the factory. Respondents also argued that they had not been actively involved in identifying solutions to the environmental challenges. The study revealed a significant association between industrial pollution as a risk and, perception of risk from other familiar health hazards. The most important factors influencing the respondents’ pollution risk perception were environmental awareness and family health status. Conclusion This study avails information to policy makers and researchers concerning public awareness and attitudes towards environmental pollution pertinent to development and implementation of environmental policies for public health.

Perceptions of risks associated with mobile phones, base stations, and other sources of electromagnetic fields (EMF) were examined. Data from a telephone survey conducted in the German- and French-speaking parts of Switzerland are presented (N = 1,015). Participants assessed both risks and benefits associated with nine different sources of EMF. Trust in the authorities regulating these hazards was assessed as well. In addition, participants answered a set of questions related to attitudes toward EMF and toward mobile phone base stations. According to respondents' assessments, high-voltage transmission lines are the most risky source of EMF. Mobile phones and mobile phone base stations received lower risk ratings. Results showed that trust in authorities was positively associated with perceived benefits and negatively associated with perceived risks. People who use their mobile phones frequently perceived lower risks and higher benefits than people who use their mobile phones infrequently. People who believed they lived close to a base station did not significantly differ in their level of risks associated with mobile phone base stations from people who did not believe they lived close to a base station. Regarding risk regulation, a majority of participants were in favor of fixing limiting values based on the worst-case scenario. Correlations suggest that belief in paranormal phenomena is related to level of perceived risks associated with EMF. Furthermore, people who believed that most chemical substances cause cancer also worried more about EMF than people who did not believe that chemical substances are that harmful. Practical implications of the results are discussed.

A growing body of empirical literature has systematically documented the reactions to research participation among participants in traumafocused research. To date, the available data has generally presented an optimistic picture regarding participants' ability to tolerate and even find benefit from their participation. However, this literature has been largely limited to cross-sectional designs. No extant literature has yet examined the perceptions of participants with psychiatric illness who are participating in randomized clinical trials (RCTs) designed to evaluate the efficacy or effectiveness of novel trauma treatments. The authors posit that negative experiences of, or poor reactions to, the research experience in the context of a trauma-focused RCT may elevate the risk of participation. Indeed, negative reactions may threaten to undermine the potential therapeutic gains of participants and promoting early drop out from the trial. Empirically assessing reactions to research participation at the pilot-study phase of a clinical trial can both provide investigators and IRB members alike with empirical evidence of some likely risks of participation. In turn, this information can be used to help shape the design and recruitment methodology of the full-scale trial. Using data from the pilot study of the Women's Self-Defense Project as a case illustration, we provide readers with concrete suggestions for empirically assessing participants' perceptions of risk involved in their participation in behaviorally oriented clinical trials.

To study job stress and upper limb biomechanical overload due to repetitive and forceful manual activities in a factory producing high fashion clothing. A total of 518 workers (433 women and 85 men) were investigated to determine anxiety, occupational stress (using the Italian version of the Karasek Job Content Questionnaire) and perception of symptoms (using the Italian version of the Somatization scale of Symptom Checklist SCL-90). Biomechanical overload was analyzed using the OCRA Check list. Biomechanical assessment did not reveal high-risk jobs, except for cutting. Although the perception of anxiety and job insecurity was within the normal range, all the workers showed a high level of job strain (correlated with the perception of symptoms) due to very low decision latitude. Occupational stress resulted partially in line with biomechanical risk factors; however, the perception of low decision latitude seems to play a major role in determining job strain. Interactions between physical and psychological factors cannot be demonstrated. Anyway, simultaneous long-term monitoring of occupational stress features and biomechanical overload could guide workplace interventions aimed at reducing the risk of adverse health effects.

Blood Pressure, Emotional Dampening, and Risk Behavior: Implications for Hypertension Development.

Elevated resting blood pressure (BP) is associated with risk for hypertension and emotional dampening, including reduced responses to emotionally meaningful stimuli. Perception of threat is a critical motivator in avoidance of risky health-damaging behavior. We hypothesize that BP-associated dampening of threat appraisal may increase risk-taking behavior. We measured resting BP, perception of affect, and risk behavior in 92 healthy, women (n=49) and men (n=43) recruited from university students and staff, and members of the surrounding community. Mean age +/- standard deviation for the sample was 21.5 +/- 4.3 year. Blood pressure was measured using an automated blood pressure monitor, and risk behavior was assessed with a modified National College Health Risk Behavior Survey. We also measured recognition of affect using the Perception of Affect Task (PAT). Risk-taking behavior was positively correlated with both systolic (SBP; r(89)=.278, p=.008) and diastolic blood pressure (DBP; r(89)=.309, p<.003). Regression analysis indicated that the association between risk-taking behavior and blood pressure was not mediated by PAT scores. Results show that persons with higher resting BP levels report increased risk-taking behavior. PAT scores, while correlated with SBP, did not mediate the relationship between BP and risk. The relationship between BP and risk behavior reflects the potential involvement of CNS regulation of both BP and emotional responsivity, and its relationship to health damaging behavior and risk for hypertension.

To identify barriers to mask wearing and to examine the factors associated with the willingness to wear masks among households. We used data sources from a study assessing the impact of 3 nonpharmaceutical interventions on the rates of influenza: exit interviews; home visits with a subset of the mask group; and a focus group. Risk perception score, univariate analysis, and logistic regression were conducted to identify the characteristics and predictors of mask use. Thematic barriers to mask wearing were identified from qualitative data obtained at home visits and focus group. Respondents from the mask group, when compared with the nonmask group, demonstrated higher risk perception scores concerning influenza (maximum score: 60, means: 37.6 and 30.2, p<.001) and increased perception of effectiveness of mask wearing (maximum score: 10, means: 7.8 and 7.3, p=.043). There was no significant association between demographic, attitudinal, or knowledge variables and adherence to wearing masks. Thematic barriers were identified such as social acceptability of mask use, comfort and fit, and perception of the risk/need for masks. Face masks may not be an effective intervention for seasonal or pandemic influenza unless the risk perception of influenza is high. Dissemination of culturally appropriate mask use information by health authorities and providers must be emphasized when educating the public. © 2010 Wiley Periodicals, Inc.

Risk perception and knowledge about osteoporosis: well informed but not aware? A cross-sectional study.

Identify the level of knowledge and risk perception of developing osteoporosis (OP) and its association with socio-demographic variables and risk factors. Individuals older than 18 years living in Mexico City were surveyed. The sample, which was designed to be representative of this population, was randomly selected and stratified by socioeconomic level, age, and sex. The Multiple Osteoporosis Prevention Survey, designed to assess OP-related knowledge, risk perception, was used. Four hundred and fifty-five individuals, homogeneously distributed according to defined strata, were surveyed. Almost 29 % (28.9 %) of subjects consumed tobacco, and 13.4 % had a family history of OP. Most subjects reported a lower-than-recommended calcium daily intake. Fifty-three and a half percent identified most risk factors adequately, and almost all (97.9 %) had received some sort of information about OP. Sixty-six and a half percent of subjects perceived OP as a serious disease; 51.5 % considered themselves to be personally responsible for acquiring it; 50.2 % were concerned about suffering from it; and 47.1 % considered it likely they would develop it. The most important variables associated with the perception of risk were age (<45 years), gender (female), and family history of OP. Subjects considered it more likely, more serious, and felt more worried and personally responsible about developing a heart condition or cancer than OP; they felt less concerned, less personally responsible, and less likely to contract AIDS or develop Alzheimer's. Individuals know a lot about OP, but they engage in risky behaviors and lack perception of their risk in developing it. Interventions should aim at raising awareness about personal responsibility and about the likelihood of developing this condition.

How are lung cancer risk perceptions and cigarette smoking related?-testing an accuracy hypothesis.

Subjective risk perception is an important theoretical construct in the field of cancer prevention and control. Although the relationship between subjective risk perception and health behaviors has been widely studied in many health contexts, the causalities and associations between the risk perception of developing lung cancer and cigarette smoking have been inconsistently reported among studies. Such inconsistency may be from discrepancies between study designs (cross-sectional versus longitudinal designs) and the three hypotheses (i.e., the behavior motivation hypothesis, the risk reappraisals hypothesis, and the accuracy hypothesis) testing different underlying associations between risk perception and cigarette-smoking behaviors. To clarify this issue, as an initial step, we examined the association between absolute and relative risk perceptions of developing lung cancer and cigarette-smoking behaviors among a large, national representative sample of 1,680 U.S. adults by testing an accuracy hypothesis (i.e., people who smoke accurately perceived a higher risk of developing lung cancer). Data from the U.S. Health Information National Trends Survey (HINTS) were analyzed using logistic regression and multivariate linear regression to examine the associations between risk perception and cigarette-smoking behaviors among 1,680 U.S. adults. Findings from this cross-sectional survey suggest that absolute and relative risk perceptions were positively and significantly correlated with having smoked >100 cigarettes during lifetime and the frequency of cigarette smoking. Only absolute risk perception was significantly associated with the number of cigarettes smoked per day among current smokers. Because both absolute and relative risk perceptions are positively related to most cigarette-smoking behaviors, this study supports the accuracy hypothesis. Moreover, absolute risk perception might be a more sensitive measurement than relative risk perception for perceived lung cancer risk. Longitudinal research is needed in the future to investigate other types of risk perception-risk behavior hypotheses-the behavior motivation and the risk reappraisals hypotheses-among nationally representative samples to further examine the causations between risk perception of obtaining lung cancer and smoking behaviors.

HIV Risk and Perceptions of Masculinity among Young Black MSM

Purpose Young Black men who have sex with men (MSM) have among the highest rates of HIV infection in the US. Although reported rates of unprotected anal intercourse are similar to MSM of other racial/ethnic backgrounds, young Black MSM (YBMSM) aged 15–22 are 5 times more likely than comparably aged white MSM to be HIV-infected. We explored contextual social-environmental factors that may influence how YBMSM assess risk, choose partners, and make decisions about condom use. Methods We analyzed semi-structured interviews with 35 YBMSM (18–24) in New York City, upstate NY, and Atlanta. We used structured analytic coding based on a theoretical scheme that emerged from the data. Results Perception of masculinity was the primary contextual factor influencing partner selection, risk assessment, and condom decision-making. Four primary themes emerged: 1) greater preference for partners perceived as masculine; 2) discomfort with allowing men perceived as feminine to be the insertive partner in anal intercourse; 3) a power dynamic such that partners perceived as more masculine made condom-use decisions within the dyad; and 4) use of potential partners’ perceived masculinity to assess HIV risk. Conclusions Perceived masculinity may play a significant role in HIV risk for YBMSM and may be an important concept to consider in prevention strategies directed towards this population.

Predicting future risk for oral diseases, treatment need and prognosis are tasks performed daily in clinical practice. A large variety of methods have been reported, ranging from clinical judgement or "gut feeling" or even patient interviewing, to complex assessments of combinations of known risk factors. In clinical practice, there is an ongoing continuous search for less complicated and more valid tools for risk assessment. There is also a lack of knowledge how different common methods relates to one another. The aim of this study was to investigate if caries risk assessment (CRA) based on clinical judgement and the Cariogram model give similar results. In addition, to assess which factors from clinical status and history agree best with the CRA based on clinical judgement and how the patient's own perception of future oral treatment need correspond with the sum of examiners risk score. Clinical examinations were performed on randomly selected individuals 20-89 years old living in Skåne, Sweden. In total, 451 individuals were examined, 51 % women. The clinical examination included caries detection, saliva samples and radiographic examination together with history and a questionnaire. The examiners made a risk classification and the authors made a second risk calculation according to the Cariogram. For those assessed as low risk using the Cariogram 69 % also were assessed as low risk based on clinical judgement. For the other risk groups the agreement was lower. Clinical variables that significantly related to CRA based on clinical judgement were DS (decayed surfaces) and combining DS and incipient lesions, DMFT (decayed, missed, filled teeth), plaque amount, history and soft drink intake. Patients' perception of future oral treatment need correlated to some extent with the sum of examiners risk score. The main finding was that CRA based on clinical judgement and the Cariogram model gave similar results for the groups that were predicted at low level of future disease, but not so well for the other groups. CRA based on clinical judgement agreed best with the number of DS plus incipient lesions.

In the present study, we investigated gender-related effects on road safety attitudes in 2681 young drivers (1458 males, 54.4%; aged 18–22) who filled out several scales assessing attitudes toward road safety issues, driving behavior in specific hypothetical situations, accident risk perception, and concerns about such a risk. We focused only on young drivers to better understand the role of gender in road safety attitudes in a period of life in which risky behaviors are widespread for males and females. Indeed, there is still no agreement as to the nature of these gender differences. According to some authors, the effects of gender on being involved in a crash due to driving skills are either non-existent or largely explained by differences in alcohol consumption. In our study, we found gender differences in road safety attitudes (i.e., “negative attitude toward traffic rules and risky driving”; “negative attitude toward drugs and alcohol” and “tolerance toward speeding”) and in driver behavior (i.e., “errors in inattentive driving” and “driving violations”). This result is consistent in all drivers coming from nine different European countries. Our analyses yielded an important finding concerning risk perception. The results indicate that the level of risk perception during driving is the same for males and females. However, these two groups differ in the level of concern about this risk, with males being less concerned about the risk of a road accident. This suggests that the main difference between these two groups is not strictly related to judgment of the perceived risk probability but rather to the level of concern experienced about the consequences of the risk. This difference between risk perception and worry could explain differences in the frequency of car accidents in the two groups. The present findings may provide new insights for the development of gender-based prevention programs. PMID:27729877

Expanding the Political Philosophy Dimension of the RISP Model: Examining the Conditional Indirect Effects of Cultural Cognition.

Hmielowski, Jay D; Wang, Meredith Y; Donaway, Rebecca R

2018-04-25

This article attempts to connect literatures from the Risk Information Seeking and Processing (RISP) model and cultural cognition theory. We do this by assessing the relationship between the two prominent cultural cognition variables (i.e., group and grid) and risk perceptions. We then examine whether these risk perceptions are associated with three outcomes important to the RISP model: information seeking, systematic processing, and heuristic processing, through a serial mediation model. We used 2015 data collected from 10 communities across the United States to test our hypotheses. Our results show that people high on group and low on grid (egalitarian communitarians) show greater risk perceptions regarding water quality issues. Moreover, these higher levels of perceived risk translate into increased information seeking, systematic processing of information, and lower heuristic processing through intervening variables from the RISP model (e.g., negative emotions and information insufficiency). These results extend the extant literature by expanding on the treatment of political ideology within the RISP model literature and taking a more nuanced approach to political beliefs in accordance with the cultural cognitions literature. Our article also expands on the RISP literature by looking at information-processing variables. © 2018 Society for Risk Analysis.

Learning that circumcision is protective against HIV: risk compensation among men and women in Cape Town, South Africa.

We examined whether knowledge of the HIV-protective benefits of male circumcision (MC) led to risk compensating behavior in a traditionally circumcising population in South Africa. We extend the current literature by examining risk compensation among women, which has hitherto been unexplored. We used data on Xhosa men and women from the 2009 Cape Area Panel Study. Respondents were asked if they had heard that MC reduces a man's risk of contracting HIV, about their perceived risk of contracting HIV, and condom use. For each gender group we assessed whether risk perception and condom use differed by knowledge of the protective benefits of MC using bivariate and then multivariate models controlling for demographic characteristics, HIV knowledge/beliefs, and previous sexual behaviors. In a further check for confounding, we used data from the 2005 wave to assess whether individuals who would eventually become informed about the protective benefits of circumcision were already different in terms of HIV risk perception and condom use. 34% of men (n=453) and 27% of women (n=690) had heard that circumcision reduces a man's risk of HIV infection. Informed men perceived slightly higher risk of contracting HIV and were more likely to use condoms at last sex (p<0.10). Informed women perceived lower HIV risk (p<0.05), were less likely to use condoms both at last sex (p<0.10) and more generally (p<0.01), and more likely to forego condoms with partners of positive or unknown serostatus (p<0.01). The results were robust to covariate adjustment, excluding people living with HIV, and accounting for risk perceptions and condom use in 2005. We find evidence consistent with risk compensation among women but not men. Further attention should be paid to the role of new information regarding MC, and drivers of HIV risk more broadly, in modulating sexual behavior among women.

Sanders, Judith Brown; Loftin, Adam; Seda, Julia S; Ehlenbeck, Chris

2014-12-01

Psychological distress in patients with a diagnosis of ductal carcinoma in situ (DCIS) or early invasive breast cancer (EIBC) can emanate from perceived risk of recurrence and is accompanied by perceived risk of death from the diseases. These factors can impart a lower quality of life that can result in poorer health outcomes. In addition, inaccurate risk perceptions can have an effect on decision making, psychosocial outcomes, and subsequent health behaviors. The purpose of this study is to assess patients with DCIS and EIBC and their perceived risk of recurrence and perceived risk of dying, and evaluate their outlook for the future, the degree of social support from spouses and significant others of patients who have been diagnosed with DCIS and EIBC, and the relationship to the patient's perceived risk perception of recurrence and dying from the diseases.

Vulnerability and social justice as factors in emergent U.S. nanotechnology risk perceptions.

PubMed

Conti, Joseph; Satterfield, Terre; Harthorn, Barbara Herr

2011-11-01

As an emerging domain of risk research, nanotechnologies engender novel research questions, including how new technologies are encountered given different framing and contextual detail. Using data from a recent U.S. national survey of perceived risks (N= 1,100), risk versus benefit framings and the specific social positions from which people encounter or perceive new technologies are explored. Results indicate that vulnerability and attitudes toward environmental justice significantly influenced risk perceptions of nanotechnology as a broad class, while controlling for demographic and affective factors. Comparative analyses of different examples of nanotechnology applications demonstrated heightened ambivalence across acceptability when risk versus benefit information was provided with application descriptions (described in short vignettes as compared to the general category "nanotechnology," absent of risk or benefit information). The acceptability of these nano-specific vignettes varied significantly in only some cases given indexes of vulnerability and attitudes toward environmental justice. However, experimental narrative analyses, using longer, more comprehensive descriptive passages, show how assessments of risks and benefits are tied to the systematically manipulated psychometric qualities of the application (its invasiveness and controllability), risk messaging from scientists, and the social implications of the technology with regard to justice. The article concludes with discussion of these findings for risk perception research and public policy related to nanotechnology and possibly other emerging technologies. © 2011 Society for Risk Analysis.

Illness perception, risk perception and health promotion self-care behaviors among Chinese patient with type 2 diabetes: A cross-sectional survey.

2018-02-01

To explore illness perception and perceived risk of developing diabetes complications in relation to health-promoting self-care behaviors among Chinese patients with type 2 diabetes. Illness and risk perceptions are important determinants of various health behaviors. However, few studies have simultaneously examined the impacts of these two constructs on self-care among diabetic patients. Data were collected on participants' characteristics, illness perception, risk perception, and health-promoting self-care behaviors over 6months among 304 subjects from three general hospitals. Significant associations between illness perception and risk perception were observed. Illness perception and/or risk perception explained an independent, small but significant proportion of the variance in each health-promoting self-care behavior. One's perceptions of illness and future risk might be influential in understanding health-promoting self-care among diabetic patients. It may be useful to improve self-management by tailoring intervention content to individuals' illness-related perceptions. Copyright © 2017 Elsevier Inc. All rights reserved.

Empirical analysis of farmers' drought risk perception: objective factors, personal circumstances, and social influence.

Drought-induced water shortage and salinization are a global threat to agricultural production. With climate change, drought risk is expected to increase as drought events are assumed to occur more frequently and to become more severe. The agricultural sector's adaptive capacity largely depends on farmers' drought risk perceptions. Understanding the formation of farmers' drought risk perceptions is a prerequisite to designing effective and efficient public drought risk management strategies. Various strands of literature point at different factors shaping individual risk perceptions. Economic theory points at objective risk variables, whereas psychology and sociology identify subjective risk variables. This study investigates and compares the contribution of objective and subjective factors in explaining farmers' drought risk perception by means of survey data analysis. Data on risk perceptions, farm characteristics, and various other personality traits were collected from farmers located in the southwest Netherlands. From comparing the explanatory power of objective and subjective risk factors in separate models and a full model of risk perception, it can be concluded that farmers' risk perceptions are shaped by both rational and emotional factors. In a full risk perception model, being located in an area with external water supply, owning fields with salinization issues, cultivating drought-/salt-sensitive crops, farm revenue, drought risk experience, and perceived control are significant explanatory variables of farmers' drought risk perceptions. © 2014 Society for Risk Analysis.

Insight and illness perception in Mexican patients with psychosis.

Insight and illness perception are two concepts of interest in the study of factors related to clinical outcome in patients with psychosis. Insight implies a risk of emotional distress for the patient. Illness perceptions, regardless of their accuracy, might be favorable or not to illness. Literature provides evidence of significant correlates of these factors with clinical outcome, but they are rarely included in a single study. 1) assessing insight and illness perception in a sample of Mexican patients who have experienced psychosis and, 2) analyzing how insight and illness perception relate to each other and how they relate to clinical status (i.e., positive, negative, and general psychopathology, depression, and anxiety). Sixty-one participants (55.7% females) were recruited from a public psychiatric hospital; insight and illness perceptions were assessed with the SUMD and the Brief-IPQ, respectively. Clinical status was assessed with the PANSS, CDS and BAI scales. Participants showed good insight, favorable illness perceptions for the cognitive and comprehension dimensions, but unfavorable for the emotional dimension. Clinical status of sample was characterized by mild symptoms. Poor insight related to positive symptoms and general psychopathology. Cognitive and emotional perceptions of illness were significantly associated to most clinical status parameters, whereas comprehension showed no significant results. The study not only replicates the significant association on insight and illness perception with clinical outcome, but shows how their patterns of interactions are different, reinforcing the idea that they are two distinct factors worthy of being habitually acknowledged in research and clinical practice.

2018-02-15

The aim of this study was to provide a systematic review of the aspects of verbal communication contributing to listener perceptions of speaker gender with a view to providing clinicians with guidance for the selection of the training goals when working with transsexual individuals. Preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) guidelines were adopted in this systematic review. Studies evaluating the contribution of aspects of verbal communication to listener perceptions of speaker gender were rated against a new risk of bias assessment tool. Relevant data were extracted, and narrative synthesis was then conducted. Meta-analyses were conducted when appropriate data were available. Thirty-eight articles met the eligibility criteria. Meta-analysis showed speaking fundamental frequency contributing to 41.6% of the variance in gender perception. Auditory-perceptual and acoustic measures of pitch, resonance, loudness, articulation, and intonation were found to be associated with listeners' perceptions of speaker gender. Tempo and stress were not significantly associated. Mixed findings were found as to the contribution of a breathy voice quality to gender perception. Nonetheless, there exists significant risk of bias in this body of research. Speech and language clinicians working with transsexual individuals may use the results of this review for goal setting. Further research is required to redress the significant risk of bias.

Public understanding of science and the perception of nanotechnology: the roles of interest in science, methodological knowledge, epistemological beliefs, and beliefs about science

2011-12-01

In this article, we report data from an online questionnaire study with 587 respondents, representative for the adult U.S. population in terms of age, gender, and level of education. The aim of this study was to assess how interest in science and knowledge as well as beliefs about science are associated with risk and benefit perceptions of nanotechnology. The findings suggest that the U.S. public is still rather unfamiliar with nanotechnology. Those who have some knowledge mainly have gotten it from TV and the Internet. The content of current media reports is perceived as fairly positive. Knowledge of scientific methods is unrelated to benefit and risk perceptions, at least when other predictors are controlled. In contrast, positive beliefs about science (e.g., its impact on economy or health) and more sophisticated epistemological beliefs about the nature of scientific knowledge are moderately linked to more positive perceptions of nanotechnology. The only exception is the perception of scientific uncertainty: This is associated with less positive evaluations. Finally, higher engagement with science is associated with higher risk perceptions. These findings show that laypersons who are engaged with science and who are aware of the inherent uncertainty of scientific evidence might perceive nanotechnology in a somewhat more differentiated way, contrary to how it is portrayed in the media today.

Lay and Expert Perceptions of Planetary Protection

NASA Technical Reports Server (NTRS)

Race, Margaret S.; MacGregor, Donald G.; Slovic, Paul

2000-01-01

As space scientists and engineers plan new missions to Mars and other planets in our solar system, they will face critical questions about the potential for biological contamination of planetary surfaces. In a society that places ever-increasing importance on the role of public involvement in science and technology policy, questions about risks of biological contamination will be examined and debated in the media, and will lead to the formation of public perceptions of planetary-contamination risks. These perceptions will, over time, form an important input to the development of space policy. Previous research in public and expert perceptions of technological risks and hazards has shown that many of the problems faced by risk-management organizations are the result of differing perceptions of risk (and risk management) between the general public and scientific and technical experts. These differences manifest themselves both as disagreements about the definition (and level) of risk associated with a scientific, technological or industrial enterprise, and as distrust about the ability of risk-management organizations (both public and private) to adequately protect people's health and safety. This report presents the results of a set of survey studies designed to reveal perceptions of planetary exploration and protection from a wide range of respondents, including both members of the general public and experts in the life sciences. The potential value of this research lies in what it reveals about perceptions of risk and benefit that could improve risk-management policies and practices. For example, efforts to communicate with the public about Mars sample return missions could benefit from an understanding of the specific concerns that nonscientists have about such a mission by suggesting areas of potential improvement in public education and information. Assessment of both public and expert perceptions of risk can also be used to provide an advanced signal of aspects of planetary exploration and protection that may be particularly sensitive or controversial and that could prove problematic from a risk-management standpoint, perhaps warranting a more stringent risk-management approach than would otherwise be the case based on technical considerations alone. The design of the study compares perceptions and attitudes about space exploration relevant to a Mars sample return mission between three respondent groups: (1) members of The Planetary Society, a group representing individuals with a strong interest in space-related issues, (2) a group of university-aged students, representing a population relatively sensitive to environmental hazards, and (3) a group of life scientists outside of the space research community. Members of The Planetary Society received the survey as part of a special issue of The Planetary Report on planetary protection, which contained a number of background articles on planetary protection and related topics. A synopsis of the issue was prepared as an introduction to the survey for the other two groups.

Illness perception ratings of high-risk newborns by mothers and clinicians: relationship to illness severity and maternal stress.

Patients' views of illness are often thought to differ from those of medical staff, although this is rarely assessed. This study examined the correspondence between mothers' and clinicians' perceptions of the same high-risk newborns, as well as with an objective measure of illness severity. We also investigated how mothers' perceptions were related to reported stress. Mothers of 99 high-risk infants admitted to either a neonatal intensive care or neonatal high dependency unit, which offers specialized but not intensive care, completed illness perception ratings of their baby's condition as well as perceived stress 3 to 5 days following admission. At the same time, a standardized measure of neonatal illness severity was calculated and the baby's primary neonatologist completed illness perceptions ratings. Unlike clinician ratings, mothers' illness perceptions were not significantly correlated with illness severity. Mothers generally rated babies in both units as sicker and having a more serious illness than did neonatologists. Whereas clinicians, compared with mothers, rated babies in intensive care as having an illness that would affect their life more and last for a longer time. Mothers rated medical treatment to be significantly more helpful than did clinicians, particularly for babies admitted to the high dependency unit. Mothers' stress was significantly associated with illness perceptions but unrelated to illness severity. Significant differences exist in the perceptions of illness severity, helpfulness of treatment, and the long-term effects of the baby's illness between parents and clinicians and this may lead to misunderstandings and misinterpretations in communication.

To assess vaccination status, potential influences upon vaccination status, and attitudes and beliefs about vaccination among hospital inpatients. This prospective, cross-sectional audit assessed vaccination status for important communicable diseases, patient perceptions about the influenza vaccination, and possible influences on vaccination status. Information was collected during face-to-face interviews using a structured questionnaire. This study was undertaken in a general teaching hospital in suburban Adelaide, South Australia. The study participants comprised a convenience sample of 50 inpatients at the hospital from April 25, 2011, to May 18, 2011. Interview and structured questionnaire at bedside. Vaccination status for seasonal influenza, pneumococcal vaccine, diphtheriatetanus-pertussis/diphtheria-tetanus vaccination, herpes zoster virus, and hepatitis B were assessed for inpatients. Qualitative information regarding patient perceptions about the influenza vaccination was also surveyed. Possible influences on vaccination status including comorbidities or high-risk conditions, area of residence, age, and gender were also assessed. The self-reported vaccination rates were: seasonal influenza vaccine 2010 (64%), seasonal influenza vaccine 2011 (52%), pneumococcal vaccine (46%), diphtheria-tetanuspertussis/ diphtheria-tetanus vaccination (70%), herpes zoster vaccination (34%), and hepatitis B vaccination (40%). Vaccination was significantly more common among those older than 64 years of age (P = 0.01), with 46% of patients older than 64 years vaccinated against influenza. There was no significant association between vaccination status and other characteristics such as gender, number of risk factors, recent hospital admission, and living in a residential facility. Regarding perceptions toward the influenza vaccine, the only factor associated with significantly increased likelihood of vaccination was self-reported risk perception (P = 0.03). The majority of patients described positive views about influenza vaccine efficacy and expressed willingness to receive the vaccine if recommended by their doctor. In this audit, vaccination status appeared to be age-dependent, with higher vaccination coverage among older patients. Those who perceived that the influenza vaccine is associated with many side effects were less likely to be vaccinated. Pharmacists may have a role in encouraging older adults to be vaccinated.

To effectively manage environmental health risks, stakeholders often need to act collectively. Stakeholders vary in their desire to act due to many factors, such as knowledge, risk perception, interests, and worldviews. Understanding their perceptions of the issues at stake is crucial to support the risk governance process. Even though concern assessment is a pivotal element of risk governance, few tools for rapid assessment are reported in the literature. We tested a rapid and relatively cheap approach, taking the Dutch debate on Intensive Animal Production Systems (IAPS) and health as an example. Dutch policy-oriented publications on IAPS and health and ten semi-structured in-depth interviews with a variety of stakeholders were analyzed to identify stakeholders and concerns involved in the Dutch debate about IAPS and health. Concerns were mapped and a stakeholder network was derived. Three classes of concerns were recognized in the discussions about IAPS and health: concerns related to health risks, concerns regarding the activity causing the risks (IAPS), and concerns about the process to control the risks. The notions of ‘trust’ and ‘scientific uncertainty’ appeared as important themes in the discussions. Argumentation based on concerns directly related to health risks, the activity causing the risk (IAPS), and its risk management can easily become muddled up in a societal debate, limiting the development of effective action perspectives. Acknowledging these multiple stakeholder concerns can clarify the positions taken by stakeholders and allow for more and other action perspectives to develop. PMID:29232902

Development of risk perception and substance use of tobacco, alcohol and cannabis among adolescents and emerging adults: evidence of directional influences.

2015-02-01

While several studies have investigated the relationship between risk perception and substance use, surprisingly little is known about mutual influences between both variables over time. The present study aimed to explore two different hypotheses separately for tobacco, alcohol and cannabis: influences from risk perception on behavior (motivational hypothesis) and influences from behavior on risk perception (risk reappraisal hypothesis). A prospective and longitudinal cross-lagged panel design was used with substance use and risk perception measured five times over the course of 10 years. Participants were 318 German youths aged 14-15 at the beginning of the study. Risk perception and substance use frequency were measured using self-reports. Structural equation modeling indicated significant influences of risk perception on substance use behavior for all substances, which supports the motivational hypothesis. Changes in risk perception predict changes in future substance use of tobacco, alcohol and cannabis. Specifically for cannabis, influences of substance use on risk perception can also be shown, thus, supporting the risk reappraisal hypothesis. While there is support for the rationale behind adequate risk perception as a goal of preventive interventions, the possibility of risk reappraisal should not be neglected, especially regarding illicit substances.

Background There has been an increase in non-daily smoking, alternative tobacco product and marijuana use among young adults in recent years. Objectives This study examined perceptions of health risks, addictiveness, and social acceptability of cigarettes, cigar products, smokeless tobacco, hookah, electronic cigarettes, and marijuana among young adults and correlates of such perceptions. Methods In Spring 2013, 10,000 students at two universities in the Southeastern United States were recruited to complete an online survey (2,002 respondents), assessing personal, parental, and peer use of each product; and perceptions of health risks, addictiveness, and social acceptability of each of these products. Results Marijuana was the most commonly used product in the past month (19.2%), with hookah being the second most commonly used (16.4%). The least commonly used were smokeless tobacco products (2.6%) and electronic cigarettes (4.5%). There were high rates of concurrent product use, particularly among electronic cigarette users. The most positively perceived was marijuana, with hookah and electronic cigarettes being second. While tobacco use and related social factors, related positively, influenced perceptions of marijuana, marijuana use and related social factors were not associated with perceptions of any tobacco product. Conclusions/Importance Marketing efforts to promote electronic cigarettes and hookah to be safe and socially acceptable seem to be effective, while policy changes seem to be altering perceptions of marijuana and related social norms. Research is needed to document the health risks and addictive nature of emerging tobacco products and marijuana and evaluate efforts to communicate such risks to youth. PMID:25268294

The Food and Drug Administration’s (FDA) The Real Cost campaign advertisements (ads) have targeted U.S. youth with messages designed to prevent and reduce tobacco use. This study examined exposure to The Real Cost campaign, including ad and slogan recall, and associations with attitudes and risk perceptions among U.S. adolescents. We analyzed data from a nationally representative sample of adolescents aged 13 to 17 years (n = 1125) surveyed by phone from October 2014 to June 2015. We assessed aided recall of and attitudes toward four campaign ads and the one slogan. Logistic regression models assessed whether aided recall of The Real Cost ads or slogan was associated with perceived likelihood of serious health consequences of cigarette smoking. Most (88%) adolescents reported seeing or hearing at least one of four ads for The Real Cost, and 54% recalled The Real Cost slogan. The majority of adolescents reported more negative attitudes toward tobacco products after seeing or hearing the ads. Recall of any The Real Cost ad was significantly associated with greater perceptions of serious health consequences of cigarette smoking (Adjusted Odd Ratios (AOR) = 5.58, 95% Confidence Interval (CI) = 1.20–25.90). The FDA’s The Real Cost campaign has achieved very high reach and is associated with more negative attitudes toward tobacco products and greater risk perceptions of cigarette smoking among U.S. adolescents.

Hines, Allyn R; Paulson, Sharon E

2006-01-01

The purpose of this study was to determine if parents and teachers differed in their views of adolescent storm and stress, and to examine the relations of these reported perceptions with parenting and teaching behaviors. Subjects were parents and teachers of middle and high school students in three school districts in the Midwest. Storm and stress beliefs were identified as parents' and teachers' perceptions of conflict, moodiness, and risk-taking behavior. Scales assessing classic/conforming and positive adolescent behaviors also were included. Self-report assessments of parenting and teaching were administered as well. Results indicated that whereas both parents and teachers held storm and stress beliefs, teachers maintained stronger perceptions than parents. Teachers also endorsed higher classic/conforming and lower positive behaviors than did parents. The results further indicated that parents' perceptions of storm and stress were related to their degree of parental responsiveness; but teachers' perceptions were not related to their teaching style. These results suggest that stereotypic beliefs of the adolescent period continue to be maintained, and that these may influence how adults interact with adolescents.

Our perception of risk contains three main aspects: (1) probability of the risk occurring; (2) the extent of possible damage; (3) the degree of voluntary or involuntary exposure to risk. History of risk assessment has been traced in several areas, such as transportation, and has largely focused on insurance. Construction projects constitute one of the oldest areas of technology where accidents continue to occur, while health has always been a fragile commodity. Urbanization has multiplied the risks of illness and death, while natural catastrophes, though still frightening, have ceded their central place to technology-based disasters in the Western perceptions of risk. The human has become the main source of danger to the very survival of the planet. The Enlightenment utopia of scientific progress resulting in social and moral progress of humanity has collided with the awareness of new technology induced risks. Life on Earth began without humans, and it may end without them. Our civilization is the first that faces an end to be brought about by our own technological ingenuity.

This study aimed to determine the effect that level of concern for osteoporosis, as well as self-perceived risk of osteoporosis and fracture, has on supplementation use, seeking medical advice, bone mineral density (BMD) testing, and antiosteoporosis medication (AOM) use. Study subjects were 1,095 female Australian participants of the Global Longitudinal study of Osteoporosis in Women (GLOW) untreated for osteoporosis at baseline. Study outcomes from self-administered questionnaires included calcium and vitamin D supplementation, self-reported seeking of medical advice regarding osteoporosis, BMD testing, and AOM use in the last 12 months at the late assessment. Logistic regression was used in the analysis. Concern significantly increased the likelihood of seeking medical advice and, however, had no significant impact on screening or treatment. Heightened self-perceived risks of osteoporosis and fracture both significantly increased the likelihood of seeking medical advice and BMD testing while elevated self-perceived risk of fracture increased AOM use. Supplementation use was not significantly associated with concern levels and risk perception. Concern and risk perceptions to osteoporosis and fracture were significantly associated with certain bone-protective behaviours. However, the disconnect between perceived osteoporosis risk and AOM use illustrates the need to emphasize the connection between osteoporosis and fracture in future education programs. PMID:25276471

Underdiagnosis of osteoporosis is common. This study investigated Swedish district nurses' perceptions of osteoporosis management. They perceived the condition as having low priority, and the consequences of this perception were insufficient awareness of the condition and perceptions of bone-specific medication as unsafe. They perceived, though, competency when working with fall prevention. Undertreatment of patients with osteoporosis is common. Sweden's medical care strategy dictates prioritisation of various conditions; while guidelines exist, osteoporosis is not prioritised. The aim of this study was to investigate district nurses' perceptions of osteoporosis management within Sweden's primary health care system. Four semi-structured focus group interviews were conducted with 13 female district nurses. The interviews were analysed using thematic analysis. The overall theme was perceiving osteoporosis management as ambiguous. The themes were perceiving barriers and perceiving opportunities. These subthemes were linked to perceiving barriers: (i) insufficient procedures, lack of time and not aware of the condition; (ii) insufficient knowledge about diagnosis and about fracture risk assessment tools; (iii) low priority condition and unclear responsibility for osteoporosis management; and (iv) bone-specific medication was sometimes perceived to be unsafe. These subthemes were linked to perceiving opportunities: (i) professional competency when discussing fall prevention in home visit programs, (ii) willingness to learn more about osteoporosis management, (iii) collaboration with other professionals and (iv) willingness to identify individuals at high risk of fracture. Osteoporosis was reported, by the district nurses, to be a low-priority condition with consequences being unawareness of the condition, insufficient knowledge about bone-specific medications, fracture risk assessment tools and procedures. These may be some of the explanations for the undertreatment of osteoporosis. At the same time, the district nurses described competency performing the home visits, which emerged as an optimal opportunity to discuss fall prevention and to introduce FRAX with the aim to identify individuals at high risk of fracture.

The exposure of pregnant women to environmental contaminants is a subject of international concern. However, the risk perception of these contaminants by health professionals (HP) has not been extensively investigated. The main objective of the PERI–HELPE study (Perception of Risk–HEaLth Professionals & Environment Study) was to assess the risk perception of environmental exposure of pregnant women by perinatal HPs. The secondary objectives were to describe the preventive attitudes of perinatal HPs concerning chemicals exposure of pregnant women and to identify the barriers to preventive attitude. A cross-sectional study was performed in 2015 in France. One hundred eighty-nine HPs (obstetricians, midwives, and general practitioners) replied to an online self-administered questionnaire (participation rate: 11%). Carbon monoxide, pesticides and lead were the contaminants most frequently perceived as a high risk for pregnant women. A minority of HPs asked women about their chemical exposure and advised them to reduce exposure. The lack of information, training and scientific evidence in environmental health were the main difficulties declared by the HPs to advise pregnant women. Despite the low response rate, our findings provide important information to encourage French health authorities to take into account the difficulties encountered by HPs and set up appropriate training programs in Environmental health.

To determine the impact of human papilloma virus (HPV) vaccination on knowledge, perception of sexual risk and need for continued safe sexual behavior among Indonesian girls. A comparative cross-sectional study was carried on in Denpasar, the capital city of Bali, Indonesia, during September 2015-February 2016. A total of 828 adolescent girls (12-16 years) were recruited to assess their knowledge on HPV/HPV vaccine, perception of sexual risks and need for continued safe sexual behavior. A total of 419 girls (50.7%) had received HPV vaccination prior to the study, 76.4% of whom (320/419) had sufficient knowledge about HPV. HPV vaccination was a strong and independent predictor of higher HPV/HPV vaccine knowledge (adjusted OR [AOR], 9.358; 95%CI: 6.816-12.849, P < 0.001). HPV vaccination (AOR, 0.107; 95%CI: 0.074-0.155, P < 0.001) and higher knowledge level (AOR, 0.667; 95%CI: 0.464-0.958, P = 0.028) were associated with lower perceived HPV risk. Despite the low risk perception, most of the vaccinated girls (408/419, 97.4%) continued to perceive higher need for safe sexual behaviors. On multivariate analysis, higher knowledge was the independent predictor for higher perceived need for safe sexual behaviors (AOR, 4.260; 95%CI: 2.016-9.001, P < 0.001). The HPV vaccination was associated with higher knowledge and appropriately lower perception of HPV risk. Despite the vaccination, most of the adolescents continued to perceive a need for safer sexual behavior. All adolescent girls should receive HPV vaccination in order to reduce cervical cancer burden in the future. © 2016 Japan Society of Obstetrics and Gynecology.

The Influence Factors and Mechanism of Societal Risk Perception

Zheng, Rui; Shi, Kan; Li, Shu

Risk perception is one of important subjects in management psychology and cognitive psychology. It is of great value in the theory and practice to investigate the societal hazards that the public cares a lot especially in Socio-economic transition period. A survey including 30 hazards and 6 risk attributes was designed and distributed to about 2, 485 residents of 8 districts, Beijing. The major findings are listed as following: Firstly, a scale of societal risk perception was designed and 2 factors were identified (Dread Risk & Unknown Risk). Secondly, structural equation model was used to analyze the influence factors and mechanism of societal risk perception. Risk preference, government support and social justice could influence societal risk perception directly. Government support fully moderated the relationship between government trust and societal risk perception. Societal risk perception influenced life satisfaction, public policy preferences and social development belief.

Risks of Plastic Debris: Unravelling Fact, Opinion, Perception, and Belief

PubMed Central

2017-01-01

Researcher and media alarms have caused plastic debris to be perceived as a major threat to humans and animals. However, although the waste of plastic in the environment is clearly undesirable for aesthetic and economic reasons, the actual environmental risks of different plastics and their associated chemicals remain largely unknown. Here we show how a systematic assessment of adverse outcome pathways based on ecologically relevant metrics for exposure and effect can bring risk assessment within reach. Results of such an assessment will help to respond to the current public worry in a balanced way and allow policy makers to take measures for scientifically sound reasons. PMID:28971682

Objective Early detection of diabetes and prediabetic states is beneficial for patients, but may be delayed by patients´ being overly optimistic about their own health. Therefore, we assessed how persons without known diabetes perceive their risk of having or developing diabetes, and we identified factors associated with perception of diabetes risk. Research design and methods 1,953 participants without previously known diabetes from the population-based, German KORA FF4 Study (59.1 years, 47.8% men) had an oral glucose tolerance test. They estimated their probability of having undiagnosed diabetes mellitus (UDM) on a six category scale, and assessed whether they were at risk of developing diabetes in the future. We cross-tabulated glycemic status with risk perception, and fitted robust Poisson regression models to identify determinants of diabetes risk perception. Results 74% (95% CI: 65–82) of persons with UDM believed that their probability of having undetected diabetes was low or very low. 72% (95% CI: 69–75) of persons with prediabetes believed that they were not at risk of developing diabetes. In people with prediabetes, seeing oneself at risk of diabetes was associated with self-rated poor general health (prevalence ratio (PR) = 3.1 (95% CI: 1.4–6.8), parental diabetes (PR = 2.6, 1.9–3.4), high educational level (PR = 1.9 (1.4–2.5)), lower age (PR = 0.7, 0.6–0.8, per 1 standard deviation increase), female sex (PR = 1.2, 0.9–1.5) and obesity (PR = 1.5, 1.2–2.0). Conclusions People with undiagnosed diabetes or prediabetes considerably underestimate their probability of having or developing diabetes. Contrary to associations with actual diabetes risk, perceived diabetes risk was lower in men, lower educated and older persons. PMID:28141837

Newly diagnosed patients with cancer require education about the disease, the available treatments and potential consequences of treatment. Greater understanding of cancer risk has been found to be associated with greater health-related quality of life, improved psychological adjustment and greater health-related behaviours. The aim of this sytematic review was to assess the effectiveness of educational interventions in improving subjective cancer risk perception and to appraise the quality of the studies. We conducted a systematic review and meta-analysis of randomised controlled trials (RCTs) and prospective observational studies. Eligible studies were identified via Medline, PsycINFO, AMED, CINAHL and Embase databases. After screening titles and abstracts, two reviewers independently assessed the eligibility of 206 full-text articles. Forty papers were included in the review; the majority of studies were conducted among breast cancer patients (n = 29) and evaluated the effect of genetic counselling on personal perceived risk (n = 25). Pooled results from RCTs (n = 12) showed that, both in the short and long term, educational interventions did not significantly influence risk perception level (standardised mean difference 0.05, 95% CI -0.24-0.34; p = 0.74) or accuracy (odds ratio = 1.96, 95% CI: 0.61-6.25; p = 0.26). Only one RCT reported a short-term difference in risk ratings (p = 0.01). Of prospective observational studies (n = 28), many did demonstrate changes in the level of perceived risk and improved risk accuracy and risk ratings in both the short and long term. However, only one (of three) observational studies reported a short-term difference in risk ratings (p < = 0.003). Further development and investigation of educational interventions using good quality, RCTs are warranted. Copyright © 2014 John Wiley & Sons, Ltd.

Our aim is to assess perception of risk of developing coronary heart disease and to examine its associations with individuals' characteristics and health behaviours among Omani people with type 2 diabetes mellitus (T2DM). Evaluating perceptions of being at risk of developing a disease may give insight into health promotion behaviours. People with diabetes are at high risk of coronary heart disease. The management of diabetes mellitus should include prevention and control of coronary heart disease. A cross-sectional correlational study was conducted. A convenience sample of 160 adults with T2DM was invited to participate in this study between November 2014 and March 2015. Descriptive and regression analyses were performed to examine associations between study variables. Perception of risk of developing coronary heart disease was significantly associated with low educational level (β = 0.191, P < .05), low income (β = 0.201, P < .05), and high level of knowledge about diabetes mellitus (β = 0.200, P < .05). People with T2DM who perceived coronary heart disease as having few moderate known outcomes and consequences reported consuming healthy diet more frequently. Teaching people with T2DM about the risk of developing coronary heart disease is essential as it could motivate them to perform health promotion behaviours, which may assist in controlling and reducing coronary heart disease. © 2017 John Wiley & Sons Australia, Ltd.

To identify whether university students who have both food-safety knowledge and beliefs perform risk-reduction behaviors. Cross-sectional research using a questionnaire that included food-safety knowledge, perceptions, risk-reduction behavior, stages for the selection of safer food based on the Transtheoretical Model, and demographic characteristics. Four universities in eastern Japan and 2 universities in western Japan. University students (n = 799). Food-safety knowledge, beliefs, and risk-reduction behaviors. Answers on measures assessing risk perception and food-safety knowledge were combined to form 4 groups of participants. Relationships among demographic characteristics, the 4 groups, risk-reduction behaviors, stage of change, and severity and susceptibility were assessed. The proportion of students who had more knowledge of food safety and a belief that "there are no 100% safe food items" was high in the group that frequently performed risk-reduction behaviors, as it was in the group who had taken a basic class about food or health care and who had, or were working toward, a food or nutrition qualification. University students who thought that there were no 100% safe food items and who had more knowledge about food safety were more likely to confirm food-safety information when selecting food.

The evolution of risk perceptions related to bovine spongiform encephalopathy--Canadian consumer and producer behavior.

PubMed

Yang, Jun; Goddard, Ellen

2011-01-01

In this study the dynamics of risk perceptions related to bovine spongiform encephalopathy (BSE) held by Canadian consumers and cow-calf producers were evaluated. Since the first domestic case of BSE in 2003, Canadian consumers and cow-calf producers have needed to make decisions on whether or not their purchasing/production behavior should change. Such changes in their behavior may relate to their levels of risk perceptions about BSE, risk perceptions that may be evolving over time and be affected by BSE media information available. An econometric analysis of the behavior of consumers and cow-calf producers might identify the impacts of evolving BSE risk perceptions. Risk perceptions related to BSE are evaluated through observed market behavior, an approach that differs from traditional stated preference approaches to eliciting risk perceptions at a particular point in time. BSE risk perceptions may be specified following a Social Amplification of Risk Framework (SARF) derived from sociology, psychology, and economics. Based on the SARF, various quality and quantity indices related to BSE media information are used as explanatory variables in risk perception equations. Risk perceptions are approximated using a predictive difference approach as defined by Liu et al. (1998). Results showed that Canadian consumer and cow-calf producer risk perceptions related to BSE have been amplified or attenuated by both quantity and quality of BSE media information. Government policies on risk communications need to address the different roles of BSE information in Canadian consumers' and cow-calf producers' behavior.

2015-01-01

Introduction Studies suggest that both affective and cognitive processes are involved in the perception of vulnerability to cancer and that affect has an early influence in this assessment of risk. We constructed a path model based on a conceptual framework of heuristic reasoning (affect, resemblance, and availability) coupled with cognitive processes involved in developing personal models of cancer causation. Methods From an eligible cohort of 16 700 women in a managed care organization, we randomly selected 2524 women at high, elevated, and average risk of ovarian cancer and administered a questionnaire to test our model (response rate 76.3%). Path analysis delineated the relationships between personal and cognitive characteristics (number of relatives with cancer, age, ideas about cancer causation, perceived resemblance to an affected friend or relative, and ovarian cancer knowledge) and emotional constructs (closeness to an affected relative or friend, time spent processing the cancer experience, and cancer worry) on perceived risk of ovarian cancer. Results Our final model fit the data well (root mean square error of approximation (RMSEA) = 0.028, comparative fit index (CFI) = 0.99, normed fit index (NFI) = 0.98). This final model (1) demonstrated the nature and direction of relationships between cognitive characteristics and perceived risk; (2) showed that time spent processing the cancer experience was associated with cancer worry; and (3) showed that cancer worry moderately influenced perceived risk. Discussion Our results highlight the important role that family cancer experience has on cancer worry and shows how cancer experience translates into personal risk perceptions. This understanding informs the discordance between medical or objective risk assessment and personal risk assessment. PMID:24916837

Bahamians and Climate Change: An Analysis of Risk Perception and Climate Change Literacy

The Commonwealth of the Bahamas is forecasted to be adversely impacted by the effects of climate change. This presentation will present the results of an assessment of the risk perception toward climate change and climate change literacy among Bahamians. 499 Bahamians from the health care and hospitality industries participated in surveys and/or focus groups and three (3) areas of climate change literacy (attitude, behavior and knowledge) were analyzed as well as risk perception. In general, 1) Bahamians demonstrated an elementary understanding of the underlying causes of climate change, 2) possessed positive attitudes toward adopting new climate change policies, and 3) are already adjusting their behaviors in light of the current predictions. This research also resulted in the development of a model of the relationships between the climate literacy subscales (attitude, behavior and knowledge) and risk perception. This study also examined information sources and their impacts on climate change literacy. As the source of information is important in assessing the quality of the information, participants also identified the source(s) of most of their climate change information. The TV news was cited as the most common source for climate change information among Bahamians. As there is limited active research generating specific climate change information in the Bahamas, all the information Bahamians receive as it pertains to climate change is generated abroad. As a result, Bahamians must decipher through to make sense of it on an individual level. From the focus groups, many of the participants have been able to view possible changes through a cultural lens and are willing to make adjustments to maintain the uniqueness and viability of the Bahamas and to preserve it for generations. Continued study of Bahamians' climate change literacy will inform adaption and mitigation policy as well as individual action.

Cricket is a very popular sport in Sri Lanka. In this setting there has been limited research; specifically, there is little knowledge of cricket injuries. To support future research possibilities, the aim of this study was to cross-culturally adapt, translate and test the reliability of an Australian-developed questionnaire for the Sri Lankan context. The Australian 'Juniors Enjoying Cricket Safely' (JECS-Aus) injury risk perception questionnaire was cross-culturally adapted to suit the Sri Lankan context and subsequently translated into the two main languages (Sinhala and Tamil) based on standard forward-back translation. The translated questionnaires were examined for content validity by two language schoolteachers. The questionnaires were completed twice, 2 weeks apart, by two groups of school cricketers (males) aged 11-15 years (Sinhala (n=24), Tamil (n=30)) to assess reliability. Test-retest scores were evaluated for agreement. Where responses were <100% agreement, Cohen's kappa (κ) statistics were calculated. Questions with moderate-to-poor test-retest reliability (κ<0.6) were reconsidered for modification. Both the Sinhala and Tamil questionnaires had 100% agreement for questions on demographic data, and 88%-100% agreement for questions on participation in cricket and injury history. Of the injury risk perception questions, 72% (Sinhala) and 90% (Tamil) questions showed a substantial (κ=0.61-0.8) and almost perfect (κ=0.81-1.0) test-retest agreement. The adapted and translated JECS-SL questionnaire demonstrated strong reliability. This is the first study to adapt the JECS-Aus questionnaire for use in a different population, providing an outcome measure for assessing injury risk perceptions in Sri Lankan junior cricketers.

Understanding challenges in familial communication of cancer risk has informed genetic service delivery. Parent-child interactions have received considerable attention, but few studies focus on young adulthood experiences within BRCA1/2 families. Young adults are approaching, or at a life stage where awareness of hereditary cancer risk is vital for informed choice of risk management options. This review assesses family communication, risk perception and cancer knowledge held by 18-40 year old individuals who have a parent with a BRCA1/2 gene mutation or carry the gene mutation themselves. Thirteen papers met the inclusion criteria. One utilized a 'mixed methods' methodology and the remaining used a qualitative approach. Findings were synthesized into themes and reported narratively. In general, parents are communicating openly about genetic risk with young adult offspring, but there is evidence that some young adults are withholding information from their parents about their own test results. Risk perception is influenced by a family history of cancer, childbearing plans and health providers' advice. Misconceptions about genetic risk appear to be common and gaps in hereditary cancer knowledge are evident. It is unclear whether incorrect knowledge was passed from parents to offspring. Health providers need to provide developmentally appropriate services for emerging adults (18-25 years old), with particular support in navigating through risk management options.

The purpose of this exploratory, descriptive, correlational study was to describe the perceived risk for diabetes complications among urban African American adults (18-75 years old) with type 2 diabetes and to explore the interrelationships among illness perception, well-being, perceptions of risk for diabetes complications, and selected physiologic measures of diabetes risk: hemoglobin A1C, blood pressure, and microalbuminuria. Urban African American adults with type 2 diabetes (N = 143) were recruited from 3 Chicago city public health clinics. They completed a demographic survey and 3 instruments: the Risk Perception Survey-Diabetes Mellitus, the 12-item Well-being Questionnaire, and the Revised Illness Perception Questionnaire. Physiologic measures included blood pressure, urine for microalbuminuria, and capillary blood for A1C. There was low perception of risk for diabetes complications, which was incongruent with the physiologic measures of risk. Less than 33% of participants saw themselves as being at high risk for developing any complications of diabetes, with the exception of vision problems (39%), despite the fact that physiologic measures of risk for diabetes complications were high in this sample. Risk perception was associated with well-being, perception of negative consequences, number of symptoms, and negative emotions related to diabetes. Risk perception was not in line with risk, as indicated by physiologic measures; thus, it is necessary to heighten this population's perception of risk for diabetes complications.

This study examined associations between televised news regarding risk for future terrorism and youth outcomes and investigated the effects of training mothers in an empirically based approach to addressing such news with children. This approach—Coping and Media Literacy (CML)—emphasized modeling, media literacy, and contingent reinforcement and was compared via randomized design to Discussion as Usual (DAU). Ninety community youth (aged 7−13 years) and their mothers viewed a televised news clip about the risk of future terrorism, and threat perceptions and state anxiety were assessed preclip, postclip, and postdiscussion. Children responded to the clip with elevated threat perceptions and anxiety. Children of CML-trained mothers exhibited lower threat perceptions than DAU youth at postclip and at postdiscussion. Additionally, CML-trained mothers exhibited lower threat perceptions and state anxiety at postclip and postdiscussion than did DAU mothers. Moreover, older youth responded to the clip with greater societal threat perception than did younger youth. Findings document associations between terrorism-related news, threat perceptions, and anxiety and support the utility of providing parents with strategies for addressing news with children. Implications and research suggestions are discussed. PMID:18665686

2018-04-01

Background: Coronary heart disease (CHD) constitutes one of the most frequent causes of death for individuals > 60 years. Lifestyle dependent risk factors are key. Hence, cardiac rehabilitation is essential for optimal CHD treatment. However, individuals rarely comprehend their illness. Motivational interviewing promotes illness perception. Aim/Methods: A randomised-controlled study was conducted to determine the effect of motivational interviewing on illness perception. Patients with stable coronary heart disease were consecutively recruited after elective percutaneous transluminal coronary angioplasty (PTCA). The intervention group received a short motivational interview (MI) about the disease and related risk factors as an intervention. The control group had usual treatment. Illness perception was assessed (Illness Perception Questionnaire-Revised) prior to the intervention and six months afterwards. Results: A total of 312 patients (intervention group: n = 148, control group: n = 164) were recruited into the study (mean age: 66.2 years). After the intervention, a significant change was observed in the domain of emotional reactions regarding the disease. Conclusion: To improve illness perception in patients with stable CHD, one short intervention with MI may have an effect. Whether intensifying the MI-intervention is more effective, requires further research.

Myocardial infarction (MI) as a life-threatening event, carrying high risk of recurrence and chronic disabling complications, increases the risk of developing acute stress disorder (ASD), posttraumatic stress disorder (PTSD), or both. The aim of this study was to investigate the relationship between illness perceptions and having ASD, PTSD, or both in patients after MI. Seventy-six patients diagnosed with acute MI were enrolled into our prospective study. We evaluated patients during the first week and six months after MI. Patients were assessed by using the Clinician Administered PTSD Scale (CAPS), the Hamilton Depression Rating Scale (HDRS), the Hamilton Anxiety Rating Scale (HARS), the Brief Illness Perception Questionnaire (BIPQ), and a semi-structured interview for socio-demographic characteristics during both the first and second evaluations. Acute stress disorder (ASD) developed in 9.2% of patients and PTSD developed in 11.9% of patients with MI. Illness perception factors of 'consequences, identity and concern' predicted the occurrence of both ASD and PTSD, whereas 'emotion' predicted only PTSD. The factors of illness perceptions predicted the induction of ASD and PTSD in patients who had acute MI.

As the number of people living at risk from volcanic hazards in the U.S. Pacific Northwest continues to rise, so does the need for improved hazard science, mitigation, and response planning. The effectiveness of these efforts relies not only on scientists and policymakers, but on individuals and their risk perception and preparedness levels. This study examines the individual knowledge, perception, and preparedness of over 500 survey respondents living or working within the lahar zones of Mount Baker and Glacier Peak volcanoes. We (1) explore the common disconnect between accurate risk perception and adequate preparedness; (2) determine how participation in hazard response planning influences knowledge, risk perception, and preparedness; and (3) assess the effectiveness of current lahar hazard maps for public risk communication. Results indicate that a disconnect exists between perception and preparedness for the majority of respondents. While 82% of respondents accurately anticipate that future volcanic hazards will impact the Skagit Valley, this knowledge fails to motivate increased preparedness. A majority of respondents also feel "very responsible" for their own protection and provision of resources during a hazardous event (83%) and believe they have the knowledge and skills necessary to respond effectively to such an event (56%); however, many of these individuals still do not adequately prepare. When asked what barriers prevent them from preparing, respondents primarily cite a lack of knowledge about relevant local hazards. Results show that participation in response-related activities—a commonly recommended solution to this disconnect—minimally influences preparedness. Additionally, although local hazard maps successfully communicate the primary hazard—97% of respondents recognize the lahar hazard—many individuals incorrectly interpret other important facets of the maps. Those who participate in response-related activities fail to understand these maps better than the general public. This study's findings will be provided to emergency managers to assist in the development of educational programs and response plans.

Risk-perception and dangerous driving among adolescents: Outcome- and behavior-focused questions yield opposite results.

PubMed

While some studies have found that those who perceive a behavior to be more risky are less likely to engage in it, others have found that those who engage in more risky behaviors see themselves as being more at-risk. Using an online questionnaire we investigated whether such conflicting findings may be due to the types of risk-questions employed in past studies. We assessed risk-perception using outcome-focused questions (e.g. the likelihood of being in an accident) and a behavior-focused question (the riskiness of speeding). Participants who reported engaging in more risky driving gave higher estimates of their chances of experiencing a negative outcome. However, those same participants gave lower estimates of the general riskiness of risky driving. Drivers may think about the risks of risky driving in different ways depending on the focus of the questions. Published by Elsevier Ltd.

In this study, the difference between the risk perception of electromagnetic waves from cellular phones and the risk perception of other factors such as environment and food was analyzed. The cause of the difference in the psychological and social factors that affect the group with high risk perception of electromagnetic waves was also analyzed. A questionnaire survey on the risk perception of electromagnetic waves from cellular phones was carried out on 1001 subjects (men and women) over the age of 20. In the group with high risk perception of electromagnetic waves from cellular phones, women had higher risk perception than men. Logistic regression analysis, where the group with high risk perception of electromagnetic waves and the group with low risk perception were used as dependent variables, indicated that the risk perception of electromagnetic waves in women was 1.815 times statistically significantly higher than the risk perception of men (95% CI: 1.340-2.457). Also, high risk perception of electromagnetic waves from cellular phones was observed when the subjects considered that they had more personal knowledge (OR: 1.416, 95% CI: 1.216-1.648), that the seriousness of the risk to future generations was high (OR: 1.410, 95% CI: 1.234-1.611), and their outrage for the occurrence of accidents related to electromagnetic waves was high (OR: 1.460, 95% CI: 1.264-1.686). The results of this study need to be sufficiently considered and reflected in designing the risk communication strategies and communication methods for the preventive measures and advice on electromagnetic waves from cellular phones. © 2014 Wiley Periodicals, Inc.

Predicting Cancer-Prevention Behavior: Disentangling the Effects of Risk Aversion and Risk Perceptions.

PubMed

Riddel, Mary; Hales, David

2018-05-16

Experimental and survey research spanning the last two decades concludes that people who are more risk tolerant are more likely to engage in risky health activities such as smoking and heavy alcohol consumption, and are more likely to be obese. Subjective perceptions of the risk associated with different activities have also been found to be associated with health behaviors. While there are numerous studies that link risk perceptions with risky behavior, it is notable that none of these controls for risk aversion. Similarly, studies that control for risk aversion fail to control for risk misperceptions. We use a survey of 474 men and women to investigate the influence of risk aversion, risk misperceptions, and cognitive ability on the choice to engage in behaviors that either increase or mitigate cancer risk. We measure optimism in two dimensions: baseline optimists are those who inaccurately believe their cancer risk to be below its expert-assessed level, while control optimists are those who believe they can reduce their risk of cancer (by changing their lifestyle choices) to a greater extent than is actually the case. Our results indicate that baseline optimism is significantly and negatively correlated with subjects' tendencies to engage in cancer-risk-reducing behaviors, and positively correlated with risky behaviors. Subjects' control misperceptions also appear to play a role in their tendency to engage in risky and prevention behaviors. When controlling for both of these types of risk misperception, risk aversion plays a much smaller role in determining health behaviors than found in past studies. © 2018 Society for Risk Analysis.

Objective. General practitioners' (GPs') perception of risk is a cornerstone of preventive care. The aims of this interview study were to explore GPs' professional and personal attitudes and experiences regarding treatment with lipid-lowering drugs and their views on patient compliance. Methods. The material was drawn from semistructured qualitative interviews. We sampled GPs purposively from ten selected practices, ensuring diversity of demographic, professional, and personal characteristics. The GPs were encouraged to describe examples from their own practices and reflect on them and were informed that the focus was their personal attitudes and experiences. Systematic text condensation was applied for analysis in order to uncover the concepts and themes. Results. The analysis revealed the following 3 main themes: (1) use of cardiovascular guidelines and risk assessment tools, (2) strategies for managing patient compliance, and (3) GPs' own risk management. There were substantial differences in the attitudes concerning all three themes. Conclusions. The substantial differences in the GPs' personal and professional risk perceptions may be a key to understanding why GPs do not always follow cardiovascular guidelines. The impact on daily clinical practice, personal consultation style, and patient behaviour with regard to prevention is worth studying further.

To examine the relationship between adolescent sexual risk-taking and perception of parental monitoring, frequency of parent-adolescent communication, and parenting style. The influences of gender, age, and ethnicity are also of interest. Data were collected from 7th-12th grade students in six rural, ethnically diverse school located in adjacent counties in a Southeastern state. A 174-item instrument assessed adolescent perceptions, behaviors and attitudes. Youth who had engaged in sexual intercourse (n = 1160) were included in the analyses. Logistic regression analyses were conducted to identify parenting practices that predicted high versus low-risk sex (defined by number of partners and use of condoms). Variables included parental monitoring, parent-adolescent communication, parenting style, parenting process interaction effects and interaction effects among these three parenting processes and gender, age and ethnicity. Analyses included frequencies, cross-tabulations and logistic regression. Parental monitoring, parental monitoring by parent-adolescent communication and parenting style by ethnicity were significant predictors of sexual risk-taking. No gender or age interactions were noted. Parental monitoring, parent-adolescent communication and parenting style are all important variables to consider when examining sexual risk-taking among adolescents.

This study investigates (i) the potential discriminative role of a clinical measure of peripheral neuropathy (PN) in assessing postural performance and fall risk and (ii) whether the integration of a simple screening vibration perception threshold (VPT) for PN in any physical (fall risk) assessment among elderly should be recommended, even if they do not suffer from DM. One hundred and ninety-five elderly were entered in a four-group model: DM with PN (D+; n = 75), DM without PN (D-; n = 28), non-diabetic elderly with idiopathic PN (C+; n = 31) and non-diabetic elderly without PN (C-; n = 61). Posturographic sway parameters were captured during different static balance conditions (AMTI AccuGait, Watertown, MA). VPT, fall data, Mini-Mental State Examination and Clock Drawing Test were registered. Two-factor repeated-measures ANOVA was used to compare between groups and across balance conditions. The groups with PN demonstrated a strikingly comparable, though bigger sway, and a higher prospective fall incidence than their peers without PN. The indication of PN, irrespective of its cause, interferes with postural control and fall incidence. The integration of a simple screening for PN (like bio-thesiometry) in any fall risk assessment among elderly is highly recommended. Implications for Rehabilitation The indication of peripheral neuropathy (PN), irrespective of its cause, interferes with postural control and fall incidence. Therefore, the integration of a simple screening for PN (like bio-thesiometry) in any fall risk assessment among elderly is highly recommended. It might be useful to integrate somatosensory stimulation in rehabilitation programs designed for fall prevention.

Insecure attachment is associated with suicidal behavior. This relationship and its possible mediators have not been examined in high-risk psychiatric inpatients with respect to the critical high-risk period following hospital discharge. Attachment styles and perception of entrapment were assessed in 200 high-risk adult psychiatric inpatients hospitalized following suicidal ideation or suicide attempt. Suicidal behaviors were evaluated with the Columbia Suicide Severity Rating Scale at 1-2 months post-discharge. Associations between different attachment styles and suicidal behaviors were assessed and mediation of attachment effects by entrapment was modeled. Fearful attachment was associated with post-discharge suicidal behavior and there was a trend-level negative association for secure attachment. In addition, entrapment mediated the relationship between fearful attachment and suicidal behavior. The current study highlights the mediating role of perceptions of entrapment in the contribution of fearful attachment to suicidal behavior in high-risk patients, suggesting entrapment as potential therapeutic target to prevent suicidal behavior in these individuals. Further research is warranted to establish the mechanisms by which entrapment experiences emerge in patients with insecure attachment styles. Copyright © 2017 Elsevier B.V. All rights reserved.

Individuals who undergo multiplex direct-to-consumer (DTC) genomic testing receive genetic risk results for multiple conditions. To date, research has not investigated the influence of individual differences in disease perceptions among consumers on testing outcomes. A total of 2037 participants received DTC genomic testing and completed baseline and follow-up surveys assessing disease perceptions and health behaviors. Participants were asked to indicate their most feared disease of those tested. Perceived seriousness and controllability of the disease via lifestyle or medical intervention were assessed. Participants most frequently reported heart attack (19.1%) and Alzheimer’s disease (18.6%) as their most feared disease. Perceived seriousness and control over the feared disease both influenced response to DTC genomic testing. Greater perceived seriousness and diminished perceived control were associated with higher, but not clinically significant levels of anxiety and distress. In some cases these associations were modified by genetic risk. No significant associations were observed for diet, exercise and screening behaviors. Individual differences in disease perceptions influence psychological outcomes following DTC genomic testing. Higher perceived seriousness may make a consumer more psychologically sensitive to test results and greater perceived control may protect against adverse psychological outcomes. Findings may inform development of educational and counseling services. PMID:24798746

This study assessed mothers' intentions to vaccinate their daughters against human papillomavirus (HPV) using the theory of planned behavior (TPB). Experience with sexually transmitted infections (STIs), beliefs about the vaccine encouraging sexual activity, and perception of daughters' risk for HPV were also examined for a relationship with intention. A random sample of mothers in a rural, Midwestern state were mailed a survey with questions pertaining to the intention to vaccinate. Attitudes were the strongest predictor of mothers' intentions to vaccinate, but intentions were not high. Subjective norms also influence intention. Mothers' risk perceptions, experience with STIs, and beliefs about the vaccine encouraging sexual activity were not related to intention. Mothers' perceptions of the daughters' risks for HPV were surprisingly low. This research provides a foundation for designing interventions to increase HPV vaccination rates. Further research should explore ways to influence mothers' attitudes and to uncover the referent groups mothers refer to for vaccination behavior.

Heat waves threaten human health given the fast changing climatic scenarios in the recent past. Adaptation to heat waves would take place when people perceive their impacts based on their knowledge. The present study examines perception level and its determinants resulting in adaptation to heat waves in Pakistan. The study used cross-sectional data from urban and peri-urban respondents of Faisalabad District. The study employs a health belief model to assess risk perception among the respondents. Logistic model is used to determine factors affecting level of knowledge, perception and adaptation to heat waves. Around 30% of peri-urban respondents have a low level of knowledge about the fatal impacts of heat waves. Risk perception of heat waves is very low among urban (57%) and peri-urban (66%) respondents. Households' knowledge on heat waves is significantly related to age, gender, education, wealth and access to health services. Determinants of perception include knowledge of heat waves, age and joint effect of marital status and knowledge while income level, family size, urban/peri-urban background, perceived barriers, perceived benefits and cues to action significantly affect adaptation to heat waves. To reduce deadly health impacts, mass awareness campaigns are needed to build perception and improve adaptation to heat waves.

A number of risk factors for developing a psychotic disorder have been investigated in the 'ultra high risk' (UHR) population, including neurocognitive abilities, social functioning and, more recently, social cognition. We aimed to review the literature on social cognition in the UHR population. Literature was restricted to English articles and identified using Pubmed, Medline, PsychINFO and CINAHLplus, as well as the reference lists of published studies and reviews. Search terms included social cognition, theory of mind, emotion recognition, attributional style, social knowledge, social perception, 'at risk mental state', psychosis prodrome 'clinical high risk' and 'ultra high risk'. Inclusion criteria were an outcome measure of a social cognition task and an UHR population defined by a structured validated instrument. Seven original research articles met the inclusion criteria, one of which was a conference abstract. One of the two studies that assessed theory of mind, two of the four studies that assessed emotion recognition and both the two studies that assessed social perception/knowledge found significant deficits in UHR patients. The single study that assessed attributional bias also reported differences in UHR patients compared with healthy controls. There is limited published literature on social cognitive performance in the UHR population. Despite this, deficits in certain social cognitive abilities do appear to be present, but further research with more reliable cross-cultural measures is needed. The characterization of social cognitive deficits in the UHR populations may aid in the identification of potential markers for development of a subsequent psychotic disorder, as well as targets for early intervention. © 2011 Blackwell Publishing Asia Pty Ltd.

Family witnessed resuscitation is the practice of enabling patients' family members to be present during resuscitation. Research is inconsistent as to the effectiveness or usefulness of this initiative. To evaluate the performance of two scales that assess perceptions of family witnessed resuscitation among a sample of health professionals, in an Australian non-teaching hospital, and explore differences in perceptions according to sociodemographic characteristics and previous experience. Descriptive, replication study, using a cross-sectional survey. An anonymous survey was distributed to 221 emergency department clinicians. Sociodemographic characteristics and perceptions of family witnessed resuscitation using the Family Presence Risk-Benefit and Family Presence Self-confidence Scales were assessed. Exploratory factor analysis was used to evaluate the performance of the scales. One hundred and fourteen doctors and nurses returned the survey (response rate of 51.6%). Both Scales were found to have a single factor structure and a high level of internal consistency. Approximately two-thirds of participants considered that family presence was a right of patients and families, and almost a quarter of respondents had invited family presence during resuscitation on more than five occasions. We found no significant differences in scale scores between doctors and nurses. Our findings confirm the validity of the Family Presence Risk-Benefit and Family Presence Self-Confidence Scales in the Australian context, and highlight the need to support clinicians in the provision of family witnessed resuscitation to all families.

It appears that a discrepancy exists between the perception of robotic-assisted surgery (RAS) and the current clinical evidence regarding robotic-assisted surgery among patients, healthcare providers, and hospital administrators. The purpose of this study was to assess whether or not such a discrepancy exists. We administered survey questionnaires via face-to-face interviews with surgical patients (n = 101), healthcare providers (n = 58), and senior members of hospital administration (n = 6) at a community hospital that performs robotic surgery. The respondents were asked about their perception regarding the infection rate, operative time, operative blood loss, incision size, cost, length of hospital stay (LOS), risk of complications, precision and accuracy, tactile sensation, and technique of robotic-assisted surgery as compared with conventional laparoscopic surgery. We then performed a comprehensive literature review to assess whether or not these perceptions could be corroborated with clinical evidence. The majority of survey respondents perceived RAS as modality to decrease infection rate, increase operative time, decrease operative blood loss, smaller incision size, a shorter LOS, and a lower risk of complications, while increasing the cost. Respondents also believed that robotic surgery provides greater precision, accuracy, and tactile sensation, while improving intra-operative access to organs. A comprehensive literature review found little-to-no clinical evidence that supported the respondent's favorable perceptions of robotic surgery except for the increased costs, and precision and accuracy of the robotic-assisted technique. There is a discrepancy between the perceptions of robotic surgery and the clinical evidence among patients, healthcare providers, and hospital administrators surveyed.

Dependence of flood risk perceptions on socioeconomic and objective risk factors

This study examines flood risk perceptions of individuals in the Netherlands using a survey of approximately 1000 homeowners. Perceptions of a range of aspects of flood risk are elicited. Various statistical models are used to estimate the influence of socioeconomic and geographical characteristics, personal experience with flooding, knowledge of flood threats, and individual risk attitudes on shaping risk belief. The study shows that in general, perceptions of flood risk are low. An analysis of the factors determining risk perceptions provides four main insights relevant for policy makers and insurers. First, differences in expected risk are consistently related to actual risk levels, since individuals in the vicinity of a main river and low-lying areas generally have elevated risk perceptions. Second, individuals in areas unprotected by dikes tend to underestimate their risk of flooding. Third, individuals with little knowledge of the causes of flood events have lower perceptions of flood risk. Fourth, there is some evidence that older and more highly educated individuals have a lower flood risk perception. The findings indicate that increasing knowledge of citizens about the causes of flooding may increase flood risk awareness. It is especially important to target individuals who live in areas unprotected by dike infrastructure, since they tend to be unaware of or ignore the high risk exposure faced.

Climate change and coastal environmental risk perceptions in Florida.

Carlton, Stuart J; Jacobson, Susan K

2013-11-30

Understanding public perceptions of climate change risks is a prerequisite for effective climate communication and adaptation. Many studies of climate risk perceptions have either analyzed a general operationalization of climate change risk or employed a case-study approach of specific adaptive processes. This study takes a different approach, examining attitudes toward 17 specific, climate-related coastal risks and cognitive, affective, and risk-specific predictors of risk perception. A survey of 558 undergraduates revealed that risks to the physical environment were a greater concern than economic or biological risks. Perceptions of greater physical environment risks were significantly associated with having more pro-environmental attitudes, being female, and being more Democratic-leaning. Perceptions of greater economic risks were significantly associated with having more negative environmental attitudes, being female, and being more Republican-leaning. Perceptions of greater biological risks were significantly associated with more positive environmental attitudes. The findings suggest that focusing on physical environment risks maybe more salient to this audience than communications about general climate change adaptation. The results demonstrate that climate change beliefs and risk perceptions are multifactorial and complex and are shaped by individuals' attitudes and basic beliefs. Climate risk communications need to apply this knowledge to better target cognitive and affective processes of specific audiences, rather than providing simple characterizations of risks.

(1) The objective of this study was to assess the risk perceptions, attitudes, knowledge, and behaviors related to typhoon among rural residents in Zhejiang province of China. A cross-sectional study was conducted among rural residents in Zhejiang province, China. Information was collected from 659 participants using a structured questionnaire. Univariate analysis and multivariable analysis were used to analyze the data. Participants were most concerned about property damage, followed by their health and life. Television, short message service (SMS), relatives and friends were the most common information sources. Most people had not been educated with disaster prevention measures. The complementary log–log (CLL) model showed that understanding typhoon warning signal, preparation time, risk perception of health damage and life threat, and fears of typhoon were independent predictors of adoption of coping behaviors. We found that: 1. Residents’ risk perception of health and life threat caused by typhoon is inadequate; 2. There is a gap between residents’ cognition or knowledge and behavior in rural areas; 3. The government should further make strategies to develop educational activities, in order to eliminate the gap and improve the ability of preparing for typhoon among rural residents. PMID:28481262

The Role of Categorical Speech Perception and Phonological Processing in Familial Risk Children With and Without Dyslexia.

This study assessed whether a categorical speech perception (CP) deficit is associated with dyslexia or familial risk for dyslexia, by exploring a possible cascading relation from speech perception to phonology to reading and by identifying whether speech perception distinguishes familial risk (FR) children with dyslexia (FRD) from those without dyslexia (FRND). Data were collected from 9-year-old FRD (n = 37) and FRND (n = 41) children and age-matched controls (n = 49) on CP identification and discrimination and on the phonological processing measures rapid automatized naming, phoneme awareness, and nonword repetition. The FRD group performed more poorly on CP than the FRND and control groups. Findings on phonological processing align with the literature in that (a) phonological processing related to reading and (b) the FRD group showed the lowest phonological processing outcomes. Furthermore, CP correlated weakly with reading, but this relationship was fully mediated by rapid automatized naming. Although CP phonological skills are related to dyslexia, there was no strong evidence for a cascade from CP to phonology to reading. Deficits in CP at the behavioral level are not directly associated with dyslexia.

In the police force, some variables such as occupational rank, sex, age and work-shift are associated with stress in workers. The aim of this paper was to determine possible differences in the perception of occupational stress at work depending on rank, sex, age and work-shift of police agents in the Community of Madrid, Spain. A cross-sectional study was conducted in 24 municipalities of the Community of Madrid. A total number of 565 police agents participated. The ranks of the police agents were: constable, corporal, sergeant and police chief. Occupational stress (psychosocial risk factors at work) was assessed with the DECORE Questionnaire. All police agents perceived psychosocial risk factors adversely; especially agents of lesser rank perceived less control, fewer rewards and scarce support. There were significant differences in the perception of insufficient rewards between constables and other categories; and between constables and corporals in the perception of insufficient organisational support. No significant differences were found in the perception of psychosocial risk factors in relation to the rest of variables. The police rank should be taken into account for the development of preventive measures to reduce stress.

(1) The objective of this study was to assess the risk perceptions, attitudes, knowledge, and behaviors related to typhoon among rural residents in Zhejiang province of China. A cross-sectional study was conducted among rural residents in Zhejiang province, China. Information was collected from 659 participants using a structured questionnaire. Univariate analysis and multivariable analysis were used to analyze the data. Participants were most concerned about property damage, followed by their health and life. Television, short message service (SMS), relatives and friends were the most common information sources. Most people had not been educated with disaster prevention measures. The complementary log-log (CLL) model showed that understanding typhoon warning signal, preparation time, risk perception of health damage and life threat, and fears of typhoon were independent predictors of adoption of coping behaviors. We found that: 1. Residents' risk perception of health and life threat caused by typhoon is inadequate; 2. There is a gap between residents' cognition or knowledge and behavior in rural areas; 3. The government should further make strategies to develop educational activities, in order to eliminate the gap and improve the ability of preparing for typhoon among rural residents.

Although flood risk perceptions and their concomitant motivations for behaviour have long been recognised as significant features of community resilience in the face of flooding events, there has, for some time now, been a poorly appreciated fissure in the accompanying literature. Specifically, rationalist and constructivist paradigms in the broader domain of risk perception provide different (though not always conflicting) contexts for interpreting evidence and developing theory. This contribution reviews the major constructs that have been applied to understanding flood risk perceptions and contextualises these within broader conceptual developments around risk perception theory and contemporary thinking around flood risk management. We argue that there is a need to re-examine and re-invigorate flood risk perception research, in a manner that is comprehensively underpinned by more constructivist thinking around flood risk management as well as by developments in broader risk perception research. We draw attention to an historical over-emphasis on the cognitive perceptions of those at risk to the detriment of a richer understanding of a wider range of flood risk perceptions such as those of policy-makers or of tax-payers who live outside flood affected areas as well as the linkages between these perspectives and protective measures such as state-supported flood insurance schemes. Conclusions challenge existing understandings of the relationship between risk perception and flood management, particularly where the latter relates to communication strategies and the extent to which those at risk from flooding feel responsible for taking protective actions.

In this study, the risk perception level of each light pollution type was analyzed, and the effects of the variables (e.g., psychometric paradigm factor, trust in the government, etc.) on the process of the increase in the risk perception were analyzed. For the sample population (1096 persons) in Korea, the risk perception levels of each light pollution type and other environmental and health risk factors were compared, and the relative magnitude was examined. In addition, to test which variables affect the group with high-risk perception of each light pollution type, a logistic regression analysis was performed. For the group with highest risk perception of light pollution, the odds ratios (OR) of all psychometric paradigms (excluding controllability) increased compared to those of the group with low-risk perception. Additionally, the level showing the acquisition of information from the media and the recollection level of media criticism on each light pollution type showed a statistically significant increase. Especially, the risk perception of light trespass increased as trust in the government decreased. The significance of this study includes the finding that the public's risk perception of light pollution was significantly affected by the psychometric paradigm factors. Moreover, this study analyzed the differences of the variables that affect the increase in the risk perception of each light pollution type and provided a theoretical framework that can practically reflect the strategy for the risk communication of light pollution.

The medical literature reports differential decision-making for children with suspected physical abuse based on race and socioeconomic status. Differential evaluation may be related to differences of risk indicators in these populations or differences in physicians' perceptions of abuse risk. Our objective was to understand the contribution of the child's social ecology to child abuse pediatricians' perception of abuse risk and to test whether risk perception influences diagnostic decision-making. Thirty-two child abuse pediatrician participants prospectively contributed 746 consultations from for children referred for physical abuse evaluation (2009-2013). Participants entered consultations to a web-based interface. Participants noted their perception of child race, family SES, abuse diagnosis. Participants rated their perception of social risk for abuse and diagnostic certainty on a 1-100 scale. Consultations (n = 730) meeting inclusion criteria were qualitatively analyzed for social risk indicators, social and non-social cues. Using a linear mixed-effects model, we examined the associations of social risk indicators with participant social risk perception. We reversed social risk indicators in 102 cases whilst leaving all injury mechanism and medical information unchanged. Participants reviewed these reversed cases and recorded their social risk perception, diagnosis and diagnostic certainty. After adjustment for physician characteristics and social risk indicators, social risk perception was highest in the poorest non-minority families (24.9 points, 95%CI: 19.2, 30.6) and minority families (17.9 points, 95%CI, 12.8, 23.0). Diagnostic certainty and perceived social risk were associated: certainty increased as social risk perception increased (Spearman correlation 0.21, p < 0.001) in probable abuse cases; certainty decreased as risk perception increased (Spearman correlation (-)0.19, p = 0.003) in probable not abuse cases. Diagnostic decisions changed in 40% of cases when social risk indicators were reversed. CAP risk perception that poverty is associated with higher abuse risk may explain documented race and class disparities in the medical evaluation and diagnosis of suspected child physical abuse. Social risk perception may act by influencing CAP certainty in their diagnosis.

HIV risk perceptions and behaviors of 236 commercial sex workers from three major Mozambican urban centers were studied using the International Rapid Assessment, Response and Evaluation (I-RARE) methodology. All were offered HIV testing and, in Maputo, syphilis testing was offered as well. Sixty-three of the 236 opted for HIV testing, with 30 (48%) testing positive for HIV. In Maputo, all 30 receiving HIV tests also had syphilis testing, with 6 (20%) found to be positive. Results include interview excerpts and qualitative results using I-RARE methodology and AnSWR-assisted analyses of the interviews and focus group sessions. PMID:24736653

Survivors of childhood cancer are at risk for a variety of treatment-related late effects and require lifelong individualized surveillance for early detection of late effects. This study assessed knowledge and perceptions of late effects risk before and after a survivor clinic visit. Young adult survivors (≥ 16 years) and parents of child survivors (< 16 years) were recruited prior to initial visit to a cancer survivor program. Sixty-five participants completed a baseline survey and 50 completed both a baseline and follow-up survey. Participants were found to have a low perceived likelihood of developing a late effect of cancer therapy and many incorrect perceptions of risk for individual late effects. Low knowledge before clinic (odds ratio = 9.6; 95% confidence interval, 1.7-92.8; P = .02) and low perceived likelihood of developing a late effect (odds ratio = 18.7; 95% confidence interval, 2.7-242.3; P = .01) were found to predict low knowledge of late effect risk at follow-up. This suggests that perceived likelihood of developing a late effect is an important factor in the individuals' ability to learn about their risk and should be addressed before initiation of education. © 2014 by Association of Pediatric Hematology/Oncology Nurses.

Compared to their non-using age peers, older marijuana users are known to have lower marijuana risk perceptions. We examined associations of older marijuana users' risk perceptions with their marijuana use patterns and substance use disorders. Data are from 2013 to 2015 National Survey of Drug Use and Health (N = 24,057 respondents aged 50+ years). Bivariate logistic regression was used to compare risk perceptions among never users, former users, and past-year users aged 50+ years. Multivariable logistic regression was used to test associations between risk perception and marijuana use status and between risk perception and marijuana use patterns. Among the total sample, former (AOR = 0.30, 95% CI = 0.27-0.32) and past-year (AOR = 0.05, 95% CI = 0.04-0.06) marijuana users had significantly lower odds of moderate/great risk perception (as opposed to no/slight risk perception) than never users. Among past-year users, odds of moderate/great risk perception were lower among those who used marijuana more frequently (AOR = 0.14, 95% CI = 0.07-0.28 for 300+ days of use compared to 1-11 days of use) and who reported any medical marijuana use (AOR = 0.27, 95% CI = 0.14-0.51). However, those who had marijuana use disorder were 3.5 times more likely to report moderate/great risk perception (AOR = 3.50, 95% CI = 1.62-7.58). Those who had a college education, had higher incomes, and resided in states with medical marijuana laws also had lower risk perceptions. Public health education on scientific evidence about marijuana's benefits and harms and age-appropriate treatment for older adults with substance use problems are needed. Research on risk perception formation using longitudinal data among older adults is also needed.

Impact of knowledge and misconceptions on benefit and risk perception of CCS.

Carbon Dioxide Capture and Storage (CCS) is assumed to be one of the key technologies in the mitigation of climate change. Public acceptance may have a strong impact on the progress of this technology. Benefit perception and risk perception are known to be important determinants of public acceptance of CCS. In this study, the prevalence and effect of cognitive concepts underlying laypeople's risk perception and benefit perception of CCS were examined in a representative survey (N=654) in Switzerland. Results confirm findings from previous qualitative studies and show a quantification of a variety of widespread intuitive concepts that laypeople hold about storage mechanisms as well as about leakage and socioeconomic issues, which all appeared to influence risk perception and benefit perception. The perception of an overpressurized reservoir and concerns about diffuse impacts furthermore amplified risk perception. Appropriate images about storage mechanisms and climate change awareness were increasing the perception of benefits. Knowledge about CO2 seemed to lower both perceived benefits and perceived risks. Implications for risk communication and management are discussed.

The incidence of human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) is increasing in the United States and may be underestimated among black individuals. Characterizing the current knowledge level among black individuals is critical to developing interventions to increase awareness. To describe the sociodemographic correlates of knowledge and risk perception of HPV and HPV-associated OPSCC among a predominantly black population. A cross-sectional survey was conducted at a drag racing event on September 12 and 13, 2015, in Madison, Illinois. The setting was a community-based oral head and neck cancer screening and education initiative. Participants were 301 drag race attendees 18 years or older who were conveniently sampled from attendees at an annual drag racing event predominantly patronized by black individuals. The primary outcome was knowledge and risk perception of HPV and HPV-associated OPSCC. An electronic-based questionnaire elicited sociodemographic information and contained oral cancer knowledge and risk perception items, which were combined to form knowledge and risk perception scores. Multivariable linear regression analysis assessed estimates of knowledge and risk perception of HPV and HPV-associated OPSCC. Of the 301 participants (111 female and 190 male) completing the questionnaire, 194 (64.5%) were black. Overall, respondents ranged in age from 18 to 78 years, with a mean (SD) age of 48.0 (13.0) years. The mean (SD) knowledge score was 5.7 (4.6) of 15, and the mean (SD) risk perception score was 2.2 (1.4) of 6. Using multivariable linear regression, we found that, for every 1-year increase in age, knowledge of HPV-associated OPSCC decreased by 5.0% and was worse in men (β = -1.26; 95% CI, -2.33 to -0.18), black vs white individuals (β = -1.29; 95% CI, -2.35 to -0.23), and those with a high school diploma or less vs college graduates (β = -3.23; 95% CI, -4.67 to -1.80). Black individuals also had lower perceived risk of developing HPV-associated OPSCC (β = -0.36; 95% CI, -0.69 to -0.02) compared with white individuals, and participants with a high school diploma or less had lower perceived risk of developing HPV-associated OPSCC compared with those with a college degree or higher (β = -0.59; 95% CI, -1.04 to -0.14). Age and sex were independent correlates of knowledge of HPV-associated OPSCC, while race and education level were correlates of both knowledge and risk perception of HPV-associated OPSCC. These findings should inform future interventions targeted at increasing knowledge of HPV-associated OPSCC in black communities.

Improvements in communications technology enable consumers to receive information through diverse channels. In the case of avian influenza, information repeated by the mass media socially amplifies the consumer awareness of risks. Facing indeterminate risks, consumers may feel anxious and increase their risk perception. When consumers trust the information published by the media, their uncertainty toward avian influenza may decrease. Consumers might take some actions to reduce risk. Therefore, this study focuses on relationships among trust in messages, risk perception and risk reduction preferences. This study administered 525 random samples and consumer survey questionnaires in different city of Taiwan in 2007. Through statistical analysis, the results demonstrate: (1) the higher the trust consumers have in messages about avian influenza, the lower their risk perceptions are; (2) the higher the consumers' risk perceptions are and, therefore, the higher their desired level of risk reductive, the more likely they are to accept risk reduction strategies; (3) consumer attributes such as age, education level, and marital status correlate with significant differences in risk perception and risk reduction preferences acceptance. Gender has significant differences only in risk reduction preferences and not in risk perception.

This study’s aim was to assess the perceptions of welding apprentices concerning welding fumes being associated with respiratory and cardiovascular disorders and assess the implementation of risk communication as a primary prevention tool in the welding training process. This quasi-experimental, non-randomized study with before-and-after design was conducted with 84 welding apprentices in Southern Brazil. Poisson Regression analysis was used. Relative Risk was the measure used with a 95% confidence interval and 5% (p ≤ 0.05) significance level. Significant association was found between perceptions of worsened symptoms of respiratory disorders caused by welding fumes and educational level (p = 0.049), the use of goggles to protect against ultraviolet rays (p = 0.023), and access to services in private health facilities without insurance coverage (p = 0.001). Apprentices younger than 25 years old were 4.9 times more likely to perceive worsened cardiovascular symptoms caused by welding fumes after risk communication (RR = 4.91; CI 95%: 1.09 to 22.2). The conclusion is that risk communication as a primary preventive measure in continuing education processes implemented among apprentices, who are future welders, was efficacious. Thus, this study confirms that risk communication can be implemented as a primary prevention tool in welding apprenticeships. PMID:25607606

Understanding and increasing awareness on individual risk for HIV infection as well as HIV risk perception's effects on different behavioral outcomes for people who inject drugs (PWID) is important for policymaking and planning purposes. The objectives of the present study were to determine whether HIV risk perception was associated with greater injection and sexual risk-taking behaviors among PWIDs. We surveyed 460 PWID in Kermanshah regarding their demographic characteristics, sexual risk behaviors, HIV risk perception, and drug-related risk behaviors in the month prior to the study. Three classes of HIV risk perception were identified using ordinal regression to determine factors associated with HIV risk perception. Study participants were categorized as follows: "low" (n = 100, 22%), "moderate" (n = 150, 32%), and "high" (n = 210, 46%) risk perception for becoming infected with HIV. The odds of categorizing as "high" risk for HIV was significantly greater in PWID that reported unprotected sex (adjusted odds ratio (AOR) 2.4, p value 0.02), receptive syringe sharing (AOR 1.8, p value 0.01), and multiple sex partners (AOR 1.4, p value 0.03). PWID who reported unprotected sex had 2.7 times the odds of "high" risk perception when compared to PWID with "low" risk perception. Findings show that PWID could rate their HIV risk with acceptable accuracy. Additionally, perceived HIV risk was associated with many risk factors for transmission of HIV, emphasizing the importance of developing targeted prevention and harm reduction programs for all domains of risk behaviors, both sexual and drug-related use.

The purposes of this study were to develop instruments that assess public knowledge of nanotechnology (PKNT), public attitudes toward nanotechnology (PANT) and conduct a pilot study for exploring the relationship between PKNT and PANT. The PKNT test was composed of six scales involving major nanotechnology concepts, including size and scale, structure of matter, size-dependent properties, forces and interactions, tools and instrumentation, as well as science, technology, and society. After item analysis, 26 multiple-choice questions were selected for the PKNT test with a KR-20 reliability of 0.91. Twenty items were developed in the PANT questionnaire which can be classified as scales of trust in government and industry, trust in scientists, and perception of benefit and risk. Cronbach alpha for the PANT questionnaire was 0.70. In a pilot study, 209 citizens, varying in age, were selected to respond to the instruments. Results indicated that about 70 % of respondents did not understand most of the six major concepts involving nanotechnology. The public tended to distrust government and industry and their levels of trust showed no relationship to their levels of knowledge about nanotechnology. However, people perceived that nanotechnology provided high benefits and high risks. Their perceptions of the benefits and risks were positively related with their knowledge level of nanotechnology. People's trust showed a negative relationship to their risk perception. Implications for using these instruments in research are discussed in this paper.

Cross-cultural differences in risk perceptions of disasters.

Public risk perceptions of mass disasters carry considerable influences, both psychologically and economically, despite their oft-times imprecise nature. Prior research has identified the presence of an optimistic bias that affects risk perception, but there is a dearth of literature examining how these perceptions differ among cultures-particularly with regard to mass disasters. The present study explores differences among Japanese, Argentinean, and North American mental health workers in their rates of the optimistic bias in risk perceptions as contrasted between natural disasters and terrorist events. The results indicate a significant difference among cultures in levels of perceived risk that do not correspond to actual exposure rates. Japanese groups had the highest risk perceptions for both types of hazards and North Americans and Argentineans had the lowest risk perceptions for terrorism. Additionally, participants across all cultures rated risk to self as lower than risk to others (optimistic bias) across all disaster types. These findings suggest that cultural factors may have a greater influence on risk perception than social exposure, and that the belief that one is more immune to disasters compared to others may be a cross-cultural phenomenon. © 2010 Society for Risk Analysis.

Objective To evaluate developmental changes, personal smoking experiences, and vicarious smoking experiences as predictors of adolescents’ perceptions of the risks and benefits of cigarette smoking over time, in order to identify new and effective targets for youth smoking prevention programs. Design 395 adolescents were surveyed every six months for two school years, from the beginning of 9th grade to the end of 10th grade. Main Outcome Measures Time, participant smoking, friend smoking, parental smoking, and sex were evaluated as predictors of smoking-related short-term risk perceptions, long-term risk perceptions, and benefits perceptions using multilevel modeling techniques. Results Perceptions of benefits did not change over time. Perceptions of risk decreased with time, but not after sex and parental smoking were included in the model. Adolescents with personal smoking experience reported decreasing perceptions of risk and increasing perceptions of benefits over time. Adolescents with more than 6 friends who smoked also reported increasing perceptions of benefits over time. Conclusions Changes in risk perceptions may not purely be the result of developmental processes, but may also be influenced by personal and vicarious experience with smoking. Findings highlight the importance of identifying and targeting modifiable factors that may influence perceptions. PMID:20939640

A clustering approach to segmenting users of internet-based risk calculators.

Risk calculators are widely available Internet applications that deliver quantitative health risk estimates to consumers. Although these tools are known to have varying effects on risk perceptions, little is known about who will be more likely to accept objective risk estimates. To identify clusters of online health consumers that help explain variation in individual improvement in risk perceptions from web-based quantitative disease risk information. A secondary analysis was performed on data collected in a field experiment that measured people's pre-diabetes risk perceptions before and after visiting a realistic health promotion website that provided quantitative risk information. K-means clustering was performed on numerous candidate variable sets, and the different segmentations were evaluated based on between-cluster variation in risk perception improvement. Variation in responses to risk information was best explained by clustering on pre-intervention absolute pre-diabetes risk perceptions and an objective estimate of personal risk. Members of a high-risk overestimater cluster showed large improvements in their risk perceptions, but clusters of both moderate-risk and high-risk underestimaters were much more muted in improving their optimistically biased perceptions. Cluster analysis provided a unique approach for segmenting health consumers and predicting their acceptance of quantitative disease risk information. These clusters suggest that health consumers were very responsive to good news, but tended not to incorporate bad news into their self-perceptions much. These findings help to quantify variation among online health consumers and may inform the targeted marketing of and improvements to risk communication tools on the Internet.

The influence of family history on cognitive heuristics, risk perceptions, and prostate cancer screening behavior.

To examine how family history of prostate cancer, risk perceptions, and heuristic decision strategies influence prostate cancer screening behavior. Men with a first-degree family history of prostate cancer (FDRs; n = 207) and men without a family history (PM; n = 239) completed a Computer Assisted Telephone Interview (CATI) examining prostate cancer risk perceptions, PSA testing behaviors, perceptions of similarity to the typical man who gets prostate cancer (representativeness heuristic), and availability of information about prostate cancer (availability heuristic). A path model explored family history as influencing the availability of information about prostate cancer (number of acquaintances with prostate cancer and number of recent discussions about prostate cancer) to mediate judgments of risk and to predict PSA testing behaviors and family history as a moderator of the relationship between representativeness (perceived similarity) and risk perceptions. FDRs reported greater risk perceptions and a greater number of PSA tests than did PM. Risk perceptions predicted increased PSA testing only in path models and was significant only for PM in multi-Group SEM analyses. Family history moderated the relationship between similarity perceptions and risk perceptions such that the relationship between these variables was significant only for FDRs. Recent discussions about prostate cancer mediated the relationships between family history and risk perceptions, and the number of acquaintances men knew with prostate cancer mediated the relationship between family history and PSA testing behavior. Family history interacts with the individuals' broader social environment to influence risk perceptions and screening behavior. Research into how risk perceptions develop and what primes behavior change is crucial to underpin psychological or public health intervention that seeks to influence health decision making.

Given the rapid rise in availability and use, understanding the perception of electronic nicotine delivery systems (ENDS) products in pregnant women is vital. As more women of reproductive age use these products, it is likely that their use during pregnancy is also increasing. This study investigated the use of ENDS and tobacco cigarettes, along with knowledge and perceptions of associated health risks in pregnant women. A cross-sectional survey was conducted at a university-based obstetrical clinic. A 32-item self-administered survey was used to collect participants' knowledge, use, and risk perceptions of ENDS and tobacco smoking. Bivariate associations of demographics and ENDS user status were explored using Chi-square or Fisher's exact tests. Average differences in agreement with perception statements across ENDS user status were tested using ANOVA with Tukey's tests for multiple comparisons. Of 382 participants, 57.9% were 21-29 years old and 60.1% had some college or higher education. 30.3% reported using both ENDS and tobacco cigarettes and 11.9% were current ENDS users. The majority of participants had adequate knowledge about the facts and safety of ENDS and there was no difference across three ENDS user status groups. ENDS users perceived significantly lower risk of ENDS and higher benefit of using ENDS to aid quitting tobacco smoking, compared to non-ENDS users. The majority of participants reported that their healthcare providers less frequently assessed ENDS use during their prenatal visits, compared to tobacco cigarette use. There is critical need for healthcare providers to increase the screening for ENDS use during pregnancy and promote awareness of risks and benefits of ENDS in pregnant women.

This study investigates whether the core bottleneck of literacy-impairment should be situated at the phonological level or at a more basic sensory level, as postulated by supporters of the auditory temporal processing theory. Phonological ability, speech perception and low-level auditory processing were assessed in a group of 5-year-old pre-school children at high-family risk for dyslexia, compared to a group of well-matched low-risk control children. Based on family risk status and first grade literacy achievement children were categorized in groups and pre-school data were retrospectively reanalyzed. On average, children showing both increased family risk and literacy-impairment at the end of first grade, presented significant pre-school deficits in phonological awareness, rapid automatized naming, speech-in-noise perception and frequency modulation detection. The concurrent presence of these deficits before receiving any formal reading instruction, might suggest a causal relation with problematic literacy development. However, a closer inspection of the individual data indicates that the core of the literacy problem is situated at the level of higher-order phonological processing. Although auditory and speech perception problems are relatively over-represented in literacy-impaired subjects and might possibly aggravate the phonological and literacy problem, it is unlikely that they would be at the basis of these problems. At a neurobiological level, results are interpreted as evidence for dysfunctional processing along the auditory-to-articulation stream that is implied in phonological processing, in combination with a relatively intact or inconsistently impaired functioning of the auditory-to-meaning stream that subserves auditory processing and speech perception.

Risk for multiple sclerosis (MS) disease-modifying therapies (DMT) must be assessed on an ongoing basis. Early concerns regarding the first-approved DMTs for MS have been mitigated, but recently licensed therapies have been linked to possibly greater risks. The objective of this review is to discuss risk assessment in MS therapeutics based on an international workshop and comprehensive literature search and recommend strategies for risk assessment/monitoring. Assessment and perception of therapeutic risks vary between patients, doctors and regulators. Acceptability of risk depends on the magnitude of risk and the demonstrated clinical benefits of any agent. Safety signals must be distinguishable from chance occurrences in a clinical trial and in long-term use of medications. Post-marketing research is crucial for assessing longer-term safety in large patient cohorts. Reporting of adverse events is becoming more proactive, allowing more rapid identification of risks. Communication about therapeutic risks and their relationship to clinical benefit must involve patients in shared decision making. It is difficult to produce a general risk-assessment algorithm for all MS therapies. Specific algorithms are required for each DMT in every treated-patient population. New and evolving risks must be evaluated and communicated rapidly to allow patients and physicians to be well informed and able to share treatment decisions. © The Author(s) 2013.

Tuberculosis (TB) is one of the main causes of death in developing countries. Awareness and perception of risk of TB could influence early detection, diagnosis and care seeking at treatment centers. However, perceptions about TB are influenced by sources of information. This study aimed to determine the association between multiple sources of information, and perceptions of risk of TB among adults aged 18-49 years. A cross-sectional study was conducted in Ntcheu district in Malawi. A total of 121 adults were sampled in a three-stage simple random sampling technique. Data were collected using a structured questionnaire. Perceptions of risk were measured using specific statements that reflected common myths and misconceptions. Low risk perception implied a person having strong belief in myths and misconceptions about TB and high risk perception meant a person having no belief in myths or misconceptions and demonstrated understanding of the disease. Females were more likely to have low risk perceptions about TB compared to males (67.7% vs. 32.5%, p = 0.01). The higher the household asset index the more likely an individual had higher risk perceptions about TB (p = 0.006). The perception of risk of TB was associated with sources of information (p = 0.03). Use of both interpersonal communication and mass media was 2.8 times more likely to be associated with increased perception of risk of TB (Odds Ratio [OR] = 2.8; 95% Confidence interva1[CI]: 3.1-15. 6; p = 0.01). After adjusting for sex and asset ownership, use of interpersonal communication and mass media were more likely to be associated with higher perception of risk of TB (OR, 2.0; 95% CI: 1.65-10.72; p = 0.003) compared with interpersonal communication only (OR 1.6, 95%; CI: 1.13-8.98, p = 0.027). The study found that there was association between multiple sources of information, and higher perceptions of risk of TB among adults aged 18-49 years.

Understanding and acknowledging the ice throw hazard - consequences for regulatory frameworks, risk perception and risk communication

This study attempts to provide the necessary framework required to make sufficiently informed decisions regarding the safety implications of ice throw. The framework elaborates on how to cope with uncertainties, and how to describe results in a meaningful and useful manner to decision makers. Moreover, it points out the moral, judicial and economical obligations of wind turbine owners such that they are able to minimize risk of ice throws as much as possible. Building on the strength of knowledge as well as accounting for uncertainty are also essential in enabling clear communication with stakeholders on the most important/critical/vital issues. With increasing empirical evidence, one can assign a higher confidence level on the expert opinions on safety. Findings regarding key uncertainties of ice risk assessments are presented here to support the ongoing IEA Wind Task 19's work on creating the international guidelines on ice risk assessment due in 2018 (Krenn et al. 2017)[1-6]. In addition the study also incorporates the findings of a Norwegian information project, which focuses on the ice throw hazard for the public (Bredesen, Flage, Butt, Winterwind 2018)[7-9]. This includes measures to reduce damage and hazard from wind turbines for the general public. Recent theory of risk assessment questions the use of risk criteria for achieving optimum risk reduction and favours the use of the ALARA (as low as reasonably achievable) principle. Given the several practical problems associated with the ALARA approach (e.g. judicial realization), a joint approach, which uses a minimum set of criteria as well as the obligation to meet ALARA is suggested (associated with acceptable cost). The actual decision about acceptance criteria or obligations is a societal one, thus suggestions can be made at best. Risk acceptance, risk perception and risk communication are inextricably linked and should thus never be considered separately. Risk communication can shape risk perception, which again is vital for defining risk acceptance. Moreover, risk communication should be seen as an opportunity to demonstrate trustworthiness and an open, responsible and caring attitude. It is important for the wind industry to avoid accidents: In Winterwind 2017 (Ronsten)[10], the importance for the wind power community to proactively take safety measures for passers-by and service personnel was emphasized: Establishing good practices and communication routines is key to avoid accidents. Visually attractive ways of presenting the risk of ice throw are recommended.

Background Addiction, or substance dependence, is nowadays considered a chronic relapsing condition. However, perceptions of addiction vary widely, also among healthcare professionals. Perceptions of addiction are thought to contribute to attitude and stigma towards patients with addiction. However, studies into perceptions of addiction among healthcare professionals are limited and instruments for reliable assessment of their perceptions are lacking. The Illness Perception Questionnaire (IPQ) is widely used to evaluate perceptions of illness. The aim of this study was to evaluate the psychometric properties of the IPQ: factor structure, internal consistency, and discriminant validity, when applied to evaluate healthcare professionals’ perceptions of addiction. Methods Participants were 1072 healthcare professionals in training and master students from the Netherlands and Indonesia, recruited from various addiction-training programs. The revised version of the IPQ was adapted to measure perceptions of addiction (IPQ-A). Maximum likelihood method was used to explore the best-fit IPQ factor structure. Internal consistency was evaluated for the final factors. The final factor structure was used to assess discriminant validity of the IPQ, by comparing illness perceptions of addiction between 1) medical students from the Netherlands and Indonesia, 2) medical students psychology students and educational science students from the Netherlands, and 3) participants with different training levels: medical students versus medical doctors. Results Factor analysis revealed an eight-factor structure for the perception subscale (demoralization, timeline chronic, consequences, personal control, treatment control, illness coherence, timeline cyclical emotional representations) and a four-factor structure for the attribution subscale (psychological attributions, risk factors, smoking/alcohol, overwork). Internal reliability was acceptable to good. The IPQ-A was able to detect differences in perceptions between healthcare professionals from different cultural and educational background and level of training. Conclusions The IPQ-A is a valid and reliable instrument to assess healthcare professionals’ perceptions of addiction. PMID:27824872

This study uses Ecological Momentary Assessment (EMA) to simultaneously capture youths’ perceptions of peer affiliates and social contexts to determine their association with youths’ current and future mood states. A sample of 82 seventh grade students (36 at risk for developing or escalating rule-breaking and substance use, and 46 randomly selected) from four schools participated. Utilizing EMA methodology students reported on their peer affiliations, perceptions of peer affiliates, moods, activities, location, and behaviors during their free time. Data from three assessment waves were collected; each wave consisted of 27 randomly prompted assessments during a week. Youth spent a large portion of their free time watching T.V., on the computer, or playing video games. Being “out and about” increased over the school year, whereas adult supervision decreased, showing an increase in potentially risky situations. Happiness was associated with affiliating with peers who were perceived as popular. Negative moods were associated with affiliating with peers by whom they are teased or treated meanly. Multilevel models found that both levels and lability of negative moods (i.e., sadness, anxiety) were predicted by risk status and affiliating with peers who tease them. Compared to boys, girls who affiliated more with peers who teased them and were classified as at-risk had more extreme negative moods and negative mood lability. EMA methodology has demonstrated the ways in which salient intrapersonal and peer processes are associated over time, which can inform efforts to prevent the development and escalation of behavior problems, substance use, and mood disorders in youth.

Food preparation and storage behaviors in the home deviating from the "best practice" food safety recommendations may result in foodborne illnesses. Currently, there are limited tools available to fully evaluate the consumer knowledge, perceptions, and behavior in the area of refrigerator safety. The current study aimed to develop a valid and reliable tool in the form of a questionnaire, the Consumer Refrigerator Safety Questionnaire (CRSQ), for assessing systematically all these aspects. Items relating to refrigerator safety knowledge (n =17), perceptions (n =46), and reported behavior (n =30) were developed and pilot tested by an expert reference group and various consumer groups to assess face and content validity (n =20), item difficulty and consistency (n =55), and construct validity (n =23). The findings showed that the CRSQ has acceptable face and content validity with acceptable levels of item difficulty. Item consistency was observed for 12 of 15 in refrigerator safety knowledge. Further, all 5 of the subscales of consumer perceptions of refrigerator safety practices relating to risk of developing foodborne disease showed acceptable internal consistency (Cronbach's α value > 0.8). Construct validity of the CRSQ was shown to be very good (P = 0.022). The CRSQ exhibited acceptable test-retest reliability at 14 days with the majority of knowledge items (93.3%) and reported behavior items (96.4%) having correlation coefficients of greater than 0.70. Overall, the CRSQ was deemed valid and reliable in assessing refrigerator safety knowledge and behavior; therefore, it has the potential for future use in identifying groups of individuals at increased risk of deviating from recommended refrigerator safety practices, as well as the assessment of refrigerator safety knowledge and behavior for use before and after an intervention.

Nanotechnology has the potential to generate new food products and new food packaging. In a mail survey in the German speaking part of Switzerland, lay people's (N=337) perceptions of 19 nanotechnology applications were examined. The goal was to identify food applications that are more likely and food applications that are less likely to be accepted by the public. The psychometric paradigm was employed, and applications were described in short scenarios. Results suggest that affect and perceived control are important factors influencing risk and benefit perception. Nanotechnology food packaging was assessed as less problematic than nanotechnology foods. Analyses of individual data showed that the importance of naturalness in food products and trust were significant factors influencing the perceived risk and the perceived benefit of nanotechnology foods and nanotechnology food packaging.

Introduction Older adults’ perception of their own risk of fall has never been included into screening tools. The goal of this study was to evaluate the predictive validity of questions on subjects’ self-perception of their own risk of fall. Methods This prospective study was conducted on a probabilistic sample of 772 Spanish community-dwelling older adults, who were followed-up for a one year period. At a baseline visit, subjects were asked about their recent history of falls (question 1: “Have you fallen in the last 6 months?”), as well as on their perception of their own risk of fall by using two questions (question 2: “Do you think you may fall in the next few months?” possible answers: yes/no; question 3: “What is the probability that you fall in the next few months?” possible answers: low/intermediate/high). The follow-up consisted of quarterly telephone calls, where the number of falls occurred in that period was recorded. Results A short questionnaire built with questions 1 and 3 showed 70% sensitivity (95% CI: 56%-84%), 72% specificity (95% CI: 68%-76%) and 0.74 area under the ROC curve (95% CI: 0.66–0.82) for prediction of repeated falls in the subsequent year. Conclusions The estimation of one’s own risk of fall has predictive validity for the occurrence of repeated falls in older adults. A short questionnaire including a question on perception of one’s own risk of fall and a question on the recent history of falls had good predictive validity. PMID:28489888

Most peer influence research examines socialization between adolescents and their best friends. Yet, adolescents also are influenced by popular peers, perhaps due to misperceptions of social norms. This research examined the extent to which out-group and in-group adolescents misperceive the frequencies of peers' deviant, health risk, and adaptive behaviors in different reputation-based peer crowds (Study 1) and the prospective associations between perceptions of high status peers' and adolescents' own substance use over 2.5 years (Study 2). Study 1 examined 235 adolescents' reported deviant (vandalism, theft), health risk (substance use, sexual risk), and adaptive (exercise, studying) behavior, and their perceptions of Jocks', Populars', Burnouts', and Brains' engagement in the same behaviors. Peer nominations identified adolescents in each peer crowd. Jocks and Populars were rated as higher status than Brains and Burnouts. Results indicated that peer crowd stereotypes are caricatures. Misperceptions of high status crowds were dramatic, but for many behaviors, no differences between Populars'/Jocks' and others' actual reported behaviors were revealed. Study 2 assessed 166 adolescents' substance use and their perceptions of popular peers' (i.e., peers high in peer perceived popularity) substance use. Parallel process latent growth analyses revealed that higher perceptions of popular peers' substance use in Grade 9 (intercept) significantly predicted steeper increases in adolescents' own substance use from Grade 9 to 11 (slope). Results from both studies, utilizing different methods, offer evidence to suggest that adolescents misperceive high status peers' risk behaviors, and these misperceptions may predict adolescents' own risk behavior engagement.

Risk perception is a fundamental element in the definition and the adoption of preventive counter-measures. In order to develop effective information and risk communication strategies, the perception of risks and the influencing factors should be known. This paper presents results of a survey on seismic risk perception in Italy conducted from January 2013 to present . The research design combines a psychometric and a cultural theoretic approach. More than 7,000 on-line tests have been compiled. The data collected show that in Italy seismic risk perception is strongly underestimated; 86 on 100 Italian citizens, living in the most dangerous zone (namely Zone 1), do not have a correct perception of seismic hazard. From these observations we deem that extremely urgent measures are required in Italy to reach an effective way to communicate seismic risk. Finally, the research presents a comparison between groups on seismic risk perception: a group involved in campaigns of information and education on seismic risk and a control group.

Background Risk communication involves conveying two inherently difficult concepts about the nature of risk: the underlying random distribution of outcomes and how a population-based proportion applies to an individual. Objective The objective of this study was to test whether 4 design factors in icon arrays—animated random dispersal of risk events, avatars to represent an individual, personalization (operationalized as choosing the avatar’s color), and a moving avatar—might help convey randomness and how a given risk applies to an individual, thereby better aligning risk perceptions with risk estimates. Methods A diverse sample of 3630 adults with no previous heart disease or stroke completed an online nested factorial experiment in which they entered personal health data into a risk calculator that estimated 10-year risk of cardiovascular disease based on a robust and validated model. We randomly assigned them to view their results in 1 of 10 risk graphics that used different combinations of the 4 design factors. We measured participants’ risk perceptions as our primary outcome, as well as behavioral intentions and recall of the risk estimate. We also assessed subjective numeracy, whether or not participants knew anyone who had died of cardiovascular causes, and whether or not they knew their blood pressure and cholesterol as potential moderators. Results Animated randomness was associated with better alignment between risk estimates and risk perceptions (F 1,3576=6.12, P=.01); however, it also led to lower scores on healthy lifestyle intentions (F 1,3572=11.1, P<.001). Using an avatar increased risk perceptions overall (F 1,3576=4.61, P=.03) and most significantly increased risk perceptions among those who did not know a particular person who had experienced the grave outcomes of cardiovascular disease (F 1,3576=5.88, P=.02). Using an avatar also better aligned actual risk estimates with intentions to see a doctor (F 1,3556=6.38, P=.01). No design factors had main effects on recall, but animated randomness was associated with better recall for those at lower risk and worse recall for those at higher risk (F 1,3544=7.06, P=.01). Conclusions Animated randomness may help people better understand the random nature of risk. However, in the context of cardiovascular risk, such understanding may result in lower healthy lifestyle intentions. Therefore, whether or not to display randomness may depend on whether one’s goal is to persuade or to inform. Avatars show promise for helping people grasp how population-based statistics map to an individual case. PMID:24642037

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

Demuth, Julie L

2018-03-23

People's past experiences with a hazard theoretically influence how they approach future risks. Yet, past hazard experience has been conceptualized and measured in wide-ranging, often simplistic, ways, resulting in mixed findings about its relationship with risk perception. This study develops a scale of past hazard experiences, in the context of tornadoes, that is content and construct valid. A conceptual definition was developed, a set of items were created to measure one's most memorable and multiple tornado experiences, and the measures were evaluated through two surveys of the public who reside in tornado-prone areas. Four dimensions emerged of people's most memorable experience, reflecting their awareness of the tornado risk that day, their personalization of the risk, the intrusive impacts on them personally, and impacts experienced vicariously through others. Two dimensions emerged of people's multiple experiences, reflecting common types of communication received and negative emotional responses. These six dimensions are novel in that they capture people's experience across the timeline of a hazard as well as intangible experiences that are both direct and indirect. The six tornado experience dimensions were correlated with tornado risk perceptions measured as cognitive-affective and as perceived probability of consequences. The varied experience-risk perception results suggest that it is important to understand the nuances of these concepts and their relationships. This study provides a foundation for future work to continue explicating past hazard experience, across different risk contexts, and for understanding its effect on risk assessment and responses. © 2018 Society for Risk Analysis.

A framework for understanding risk perception, explored from the perspective of the water practitioner.

Sustainable urban water systems are likely to be hybrids of centralized and decentralized infrastructure, managed as an integrated system in water-sensitive cities. The technology for many of these systems is available. However, social and institutional barriers, which can be understood as deeply embedded risk perceptions, have impeded their implementation. Risk perceptions within the water sector are often unrecognized or unacknowledged, despite their role in risk management generally in informing value judgments and specifically in ranking risks to achieve management objectives. There has been very little examination of the role of these risk perceptions in advancing more sustainable water supply management through the adoption of alternative sources. To address this gap, this article presents a framework that can be used as a tool for understanding risk perceptions. The framework is built on the relational theory of risk and presents the range of human phenomena that might influence the perception of an "object at risk" in relation to a "risk object." It has been synthesized from a critical review of theoretical, conceptual, and empirical studies of perception broadly and risk perception specifically, and interpreted in relation to water practitioners. For a water practitioner, the risk object might be an alternative water system, a component, a process, or a technology, and the object at risk could be public or environmental health, profitability, or professional reputation. This framework has two important functions: to allow practitioners to understand their own and others' risk perceptions, which might differ, and to inform further empirical research. © 2013 Society for Risk Analysis.

In view of the present and proposed amendments to the Labor Code as well as bearing in mind anticipated harmonization of regulations in this area with those of EEC, the authors emphasize the need for well developed methodology for assessing chemical safety in an occupational environment with special reference to health effects in people exposed to chemicals. Methods for assessing health risk induced by work under conditions of exposure to chemicals were divided into: methods for assessing technological/processing risk, and methods for assessing health risk related to the toxic effect of chemicals. The need for developing means of risk communication in order to secure proper risk perception among people exposed to chemicals and risk managers responsible for prevention against chemical hazards was also stressed. It is suggested to establish a centre for chemical substances in order to settle down all issues pertaining to human exposure to chemicals. The centre would be responsible, under the provisions of the Chemical Substances Act, for the qualitative and quantitative analysis of the present situation and for the development of guidelines on assessment of health risk among persons exposed to chemicals.

Don't know responses to cognitive and affective risk perception measures: Exploring prevalence and socio-demographic moderators.

Many people report uncertainty when appraising their risk of cancer and other diseases, but prior research about the topic has focused solely on cognitive risk perceptions. We investigated uncertainty related to cognitive and affective risk questions. We also explored whether any differences in uncertainty between cognitive and affective questions varied in magnitude by item-specific or socio-demographic characteristics. Secondary analysis of data collected for a 2 × 2 × 3 full-factorial risk communication experiment (N = 835) that was embedded within an online survey. We investigated the frequency of 'don't know' responses (DKR) to eight perceived risk items that varied according to whether they assessed (1) cognitive versus affective perceived risk, (2) absolute versus comparative risk, and (3) colon cancer versus 'any exercise-related diseases'. Socio-demographics were as follows: sex, age, education, family history, and numeracy. We analysed the data using multilevel logistic regression. The odds of DKR were lower for affective than cognitive perceived risk (OR = 0.64, p < .001). This difference occurred for absolute but not comparative risk perceptions (interaction effect, p = .004), but no interactions for disease type or demographic characteristics were found (ps > .05). Lower uncertainty for affective (vs. cognitive) absolute perceived risk items is consistent with research stating: (1) Risk perceptions are grounded in people's feelings about a hazard, and (2) feelings are easier for people to access than facts. Including affective perceived risk items in health behaviour surveys may reduce missing data and improve data quality. Statement of contribution What is already known on this subject? Many people report that they don't know their risk (i.e., risk uncertainty). Evidence is growing for the importance of feelings of risk in explaining health behaviour. Feelings are easier for people to access than facts. What does this study add? Don't know responding is higher for absolute cognitive than absolute affective risk questions. This difference does not vary in magnitude by demographic characteristics. Affective perceived risk questions in surveys may reduce missing data and improve data quality. © 2018 The British Psychological Society.

The presented survey investigates risk and exposure perceptions of radio frequency electromagnetic fields (RF EMF) associated with base stations, mobile phones and other sources, the key issue being the interaction between both sets of perceptions. The study is based on a cross-sectional design, and conducted with an online sample of 838 citizens from Portugal. The results indicate that respondents' intuitive exposure perception differs from the actual exposure levels. Furthermore, exposure and risk perceptions are found to be highly correlated. Respondents' beliefs about exposure factors, which might influence possible health risks, is appropriate. A regression analysis between exposure characteristics, as predictor variables, and RF EMF risk perception, as the response variable, indicates that people seem to use simple heuristics to form their perceptions. What is bigger, more frequent and longer lasting is seen as riskier. Moreover, the quality of exposure knowledge is not an indicator for amplified EMF risk perception. These findings show that exposure perception is key to future risk communication.

Cigarette graphic warning labels elicit negative emotion, which increases risk perceptions through multiple processes. We examined whether this emotion simultaneously affects motivated cognitions like smoking myth endorsement (e.g. 'exercise can undo the negative effects of smoking') and perceptions of cigarette danger versus other products. 736 adult and 469 teen smokers/vulnerable smokers viewed one of three warning label types (text-only, low emotion graphic or high emotion graphic) four times over two weeks. Emotional reactions to the warnings were reported during the first and fourth exposures. Participants reported how often they considered the warnings, smoking myth endorsement, risk perceptions and perceptions of cigarette danger relative to smokeless tobacco and electronic cigarettes. In structural equation models, emotional reactions influenced risk perceptions and smoking myth endorsement through two processes. Emotion acted as information about risk, directly increasing smoking risk perceptions and decreasing smoking myth endorsement. Emotion also acted as a spotlight, motivating consideration of the warning information. Warning consideration increased risk perceptions, but also increased smoking myth endorsement. Emotional reactions to warnings decreased perceptions of cigarette danger relative to other products. Emotional reactions to cigarette warnings increase smoking risk perceptions, but also smoking myth endorsement and misperceptions that cigarettes are less dangerous than potentially harm-reducing tobacco products.

The purpose of this study was to investigate the contribution of actual cardiovascular disease (CVD) risk, as well as, individual, psychosocial, and work-related factors as predictors of CVD risk perception among Korean blue-collar workers. The participants were 238 Korean blue-collar workers who worked in small companies. Data were collected through a survey; anthropometric and blood pressure measures; and blood sampling for lipid levels. Blue-collar workers had high actual CVD risk and low CVD risk perception. The significant predictors of risk perception included perceived health status, alcohol consumption, knowledge of CVD risk, actual CVD risk, decision latitude, and shift work. The model explained 26% of the variance in CVD risk perception. The result suggests when occupational health nurses are giving routine health examination in small companies, they can enhance CVD risk perception in blue-collar workers by providing essential information about CVD risk factors and personal counseling on the individual worker's CVD risk status.

[Perceived risks of food contaminants].

Food contaminants can pose a serious health threat. In order to carry out adequate risk communication measures, the subjective risk perception of the public must be taken into account. In this context, the breadth of the topic and insufficient terminological delimitations from residues and food additives make an elaborate explanation of the topic to consumers indispensable. A representative population survey used language adequate for lay people and a clear definition of contaminants to measure risk perceptions with regard to food contaminants among the general public. The study aimed to assess public awareness of contaminants and the perceived health risks associated with them. In addition, people's current knowledge and need for additional information, their attitudes towards contaminants, views on stakeholder accountability, as well as compliance with precautionary measures, such as avoiding certain foods to reduce health risks originating from contaminants, were assessed. A representative sample of 1001 respondents was surveyed about food contaminants via computer-assisted telephone interviewing. The majority of respondents rated contaminants as a serious health threat, though few of them spontaneously mentioned examples of undesirable substances in foods that fit the scientific or legal definition of contaminants. Mercury and dioxin were the most well-known contaminants. Only a minority of respondents was familiar with pyrrolizidine alkaloids. The present findings highlight areas that require additional attention and provide implications for risk communication geared to specific target groups.

Actuarial assessment of violence risk in hospital-based partner assault clinics.

Hospital-based partner assault clinics are a relatively recent addition to the community response to partner violence. In this study, 66% of 111 women attending hospital clinics for partner assault were physically injured and 43% reported death threats. Few concurrently used other services (shelters or police) and most relied on female friends and relatives for help. Many participants who currently lived with the perpetrator were contemplating leaving but only a third had made plans to do so. Participants faced an unusually high risk of future assault, according to both victim interview using the ODARA actuarial risk assessment and their own perceptions. Findings imply an important role for partner assault clinics and the feasibility of the victim service sector's using the same actuarial risk assessments as the criminal justice system.

Enduring Consequences From the War on Drugs: How Policing Practices Impact HIV Risk Among People Who Inject Drugs in Baltimore City.

Neighborhood-level characteristics, including police activity, are associated with HIV and Hepatitis C injection risk-behaviors among people who inject drugs (PWID). However, the pathways through which these neighborhood perceptions shape individual-level HIV risk behaviors are unclear. This study helps to explain perceived behaviors between perceived neighborhood police activity and HIV injection risk behavior (i.e., injection syringe/tool sharing in the previous 6 months). A sample of (n = 366) PWIDs who self-reported recent use were recruited using community-based outreach methods in Baltimore, Maryland. Neighborhood police perceptions were assessed by asking participants whether they would (1) be more likely to ask others to share injection tools in the context of heightened police activity and (2) be less likely to carry syringes with them due to fear of arrest. Poisson regression with robust variance was used to identify statistical relationships. Recent police encounters, frequency of heroin injection, and sociodemographic characteristics were controlled for in the model. Neighborhood police perceptions shaped injection-risk behavior. Half of the sample (49%) reported an aversion of carrying personal syringes, due to fear of arrest. Those who agreed they would be more likely to ask others to share injection equipment in the context of heightened police activity were more likely to share syringes (21% vs. 3%, p <.01). Adjusted models showed that syringe sharing was independently associated with asking to borrow equipment in neighborhoods with perceived heightened police activity (aPR: 2.22, 95% confidence interval (CI): 1.7, 3.0). This study sheds light on how police perceptions may influence injection risk behavior. While these relationships require further elucidation, this study suggests that public health interventions aiming to reduce HIV risk would benefit from improving community-police relationships.

Gender and perceptions of romantic partners' sexual risk.

Research shows that in most situations, women perceive themselves to be at greater risk of harm than do men. Gustafson's gender role perspective on risk perception suggests that this is because women are socialized to feel that they need protection, especially from men. Based on Gustafson's gender role perspective on sex differences in risk perception, we predicted that in at least one context, perception of romantic partners' sexual risk, this gender difference would be reversed. Specifically, women should rate boyfriends as having lower risk for sexually transmitted infections (STIs) than boyfriends rate themselves having. In two studies, we examined heterosexual couples and compared women's perceptions of their boyfriends' sexual risk level with the boyfriend's self-perception of sexual risk. Self-reported measures of risk for STIs, perception of romantic partners' risk for STIs. On multiple measures, women rated their boyfriends as having a lower risk for STIs than the men rated themselves. Men did not show this pattern and, in some cases, showed the reverse pattern of perceiving their girlfriends to have a greater level of risk than girlfriends themselves believed they had. Consistent with Gustafson's gender role perspective on risk perception, heterosexual women perceived their romantic partners as relatively less risky in terms of STI risk than men perceived themselves. One potential implication of this finding is that women may be less likely to protect themselves against disease in close romantic relationships because they believe that their partners are low risk, regardless of the partners' actual risk levels.

Many patients have difficulty interpreting risks described in statistical terms as percentages. Computer game technology offers the opportunity to experience how often an event occurs, rather than simply read about its frequency. . To assess effects of interactive graphics on risk perceptions and decisions. . Electronic questionnaire. Participants and setting. Respondents (n = 165) recruited online or at an urban hospital. Intervention. Health risks were illustrated by either static graphics or interactive game-like graphics. The interactive search graphic was a grid of squares, which, when clicked, revealed stick figures underneath. Respondents had to click until they found a figure affected by the disease. Measurements. Risk feelings, risk estimates, intention to take preventive action. . Different graphics did not affect mean risk estimates, risk feelings, or intention. Low-numeracy participants reported significantly higher risk feelings than high-numeracy ones except with the interactive search graphic. Unexpectedly, respondents reported stronger intentions to take preventive action when the intention question followed questions about efficacy and disease severity than when it followed perceived risk questions (65% v. 34%; P < 0.001). When respondents reported risk feelings immediately after using the search graphic, the interaction affected perceived risk (the longer the search to find affected stick figures, the higher the risk feeling: ρ = 0.57; P = 0.009). Limitations. The authors used hypothetical decisions. . A game-like graphic that allowed consumers to search for stick figures affected by disease had no main effect on risk perception but reduced differences based on numeracy. In one condition, the game-like graphic increased concern about rare risks. Intentions for preventive action were stronger with a question order that focused first on efficacy and disease severity than with one that focused first on perceived risk.

Expert's risk evaluation of radiation exposure strongly influences the public's risk perception. Experts can inform laypersons of significant radiation information including health knowledge based on experimental data. However, some experts' radiation risk perception is often based on non-conclusive scientific evidence (i.e., radiation levels below 100 millisievert), which is currently under debate. Examining perception levels among experts is important for communication with the public since these individual's opinions have often exacerbated the public's confusion. We conducted a survey of Korean radiation researchers to investigate their perceptions of the risks associated with radiation exposure below 100 millisievert. A linear regression analysis revealed that having ≥ 11 years' research experience was a critical factor associated with radiation risk perception, which was inversely correlated with each other. Increased opportunities to understand radiation effects at < 100 millisievert could alter the public's risk perception of radiation exposure. In addition, radiation researchers conceived that more scientific evidence reducing the uncertainty for radiation effects < 100 millisievert is necessary for successful public communication. We concluded that sustained education addressing scientific findings is a critical attribute that will affect the risk perception of radiation exposure.

Lyme disease (LD) accounts for most vector-borne disease reports in the U.S., and although its existence in Alabama remains controversial, other tick-borne illnesses (TBI) such as Southern Tick-Associated Rash Illness (STARI) pose a health concern in the state. Phase One of the Marshall Space Flight Center-UAB DEVELOP study of TBI identified the presence of the chain of infection for LD (Ixodes scapularis ticks carrying Borrelia burgdorferi bacteria) and STARI (Amblyomma americanum ticks and an as-yet-unconfirmed agent) in Alabama. Both LD and STARI are associated with the development of erythema migrans rashes around an infected tick bite, and while treatable with oral antibiotics, a review of educational resources available to state residents revealed low levels of prevention information. To improve prevention, recognition, and treatment of TBI in Alabama, Phase Two builds a health communication campaign based on vector habitat mapping and risk perception assessment. NASA Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite imagery identified likely tick habitats using remotely sensed measurements of vegetation vigor (Normalized Difference Vegetation Index) and soil moisture. Likely tick habitats, identified as those containing both high vegetation density and soil moisture, included Oak Mountain State Park, Bankhead National Forest, and Talladega National Forest. To target a high-risk group -- outdoor recreation program participants at Alabama universities -- the study developed a behavior survey instrument based on existing studies of LD risk factors and theoretical constructs from the Social Ecological Model and Health Belief Model. The survey instrument was amended to include geographic variables in the assessment of TBI knowledge, attitudes, and prevention behaviors, and the vector habitat model will be expanded to incorporate additional environmental variables and in situ data. Remotely sensed environmental data combined with risk perception assessments inform an ongoing outreach campaign consisting of stakeholder meetings and educational seminars.

The intensity, frequency, and duration of heat waves are expected to increase with climate change. In this study, we found a significant difference of public perceived effects of heat waves and trust in government among urban, suburban, and rural districts. Rural residents had a significant higher effect perception than urbanites and also showed stronger willingness to have medical insurance or regular physical examinations. Meanwhile, suburban residents had the lowest trust perception in government among these three districts, which may be due to suburban districts' unique social structure and complex social issues. Besides, we assessed the relationship between the factor effect and demographic variables. The results showed that urban respondents' effect perception was significantly related to heat wave experiences. Suburban respondents' effect perception was significantly related to age, income, and heat wave experiences. And rural respondents' effect perception was significantly related to income and chronic diseases. Based on our results, much more attention needs to be paid to rural districts. The government should strengthen infrastructure construction such as cooling centers, improve emergency response plans and mechanisms, and increase reserves of emergency supplies in rural districts. Also, targeted risk communication is of the equal importance to aid the policy-makers improving the relationship with the public and regaining the public's trust and support.

This study aims to (1) assess ethnic differences in health care access and health outcome between Asian Americans and whites and between Asian American subgroups, (2) examine effects of cultural factors, and (3) investigate moderating effects of health risk behaviors between cultural characteristics and health care access and outcome. Data were derived from the 2007 California Health Interview Survey. Asian Americans (n = 4,462) and whites (n = 4,470) were included. There were significant ethnic differences in health care access and health perception between Asian Americans and Whites and across Asian American subgroups. Health risk behaviors moderated relationships between cultural factors and health care access and outcome. Findings reveal that ethnicity affects an individual's health care access and health perception, and their health behaviors are an important factor that may improve or worsen outcomes. This study may increase our knowledge base of research and interventions to enhance ethnic minority populations' health care accessibility and perceptions.

The risk perception paradox--implications for governance and communication of natural hazards.

2013-06-01

This article reviews the main insights from selected literature on risk perception, particularly in connection with natural hazards. It includes numerous case studies on perception and social behavior dealing with floods, droughts, earthquakes, volcano eruptions, wild fires, and landslides. The review reveals that personal experience of a natural hazard and trust--or lack of trust--in authorities and experts have the most substantial impact on risk perception. Cultural and individual factors such as media coverage, age, gender, education, income, social status, and others do not play such an important role but act as mediators or amplifiers of the main causal connections between experience, trust, perception, and preparedness to take protective actions. When analyzing the factors of experience and trust on risk perception and on the likeliness of individuals to take preparedness action, the review found that a risk perception paradox exists in that it is assumed that high risk perception will lead to personal preparedness and, in the next step, to risk mitigation behavior. However, this is not necessarily true. In fact, the opposite can occur if individuals with high risk perception still choose not to personally prepare themselves in the face of a natural hazard. Therefore, based on the results of the review, this article offers three explanations suggesting why this paradox might occur. These findings have implications for future risk governance and communication as well as for the willingness of individuals to invest in risk preparedness or risk mitigation actions. © 2012 Society for Risk Analysis.

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

An implicit assumption of risk perception studies is that concerns expressed in questionnaires reflect concerns in everyday life. The aim of the present study is to check this assumption, i.e., the extrapolability of risk perceptions expressed in a survey, to risk perceptions in everyday life. To that end, risk perceptions were measured by a multidimensional approach. In addition to the traditional focus on measuring the magnitude of risk perceptions, the thematic relevance (how often people think about a risk issue) and the discursive relevance (how often people think about or discuss a risk issue) of risk perceptions were also collected. Taking into account this extended view of risk perception, an online survey was conducted in six European countries with 2454 respondents, referring to radio frequency electromagnetic field (RF EMF) risk potentials from base stations, and access points, such as WiFi routers and cell phones. The findings reveal that the present study’s multidimensional approach to measuring risk perception provides a more differentiated understanding of RF EMF risk perception. High levels of concerns expressed in questionnaires do not automatically imply that these concerns are thematically relevant in everyday life. We use thematic relevance to distinguish between enduringly concerned (high concern according to both questionnaire and thematic relevance) and not enduringly concerned participants (high concern according to questionnaire but no thematic relevance). Furthermore, we provide data for the empirical value of this distinction: Compared to other participants, enduringly concerned subjects consider radio frequency electromagnetic field exposure to a greater extent as a moral and affective issue. They also see themselves as highly exposed to radio frequency electromagnetic fields. However, despite these differences, subjects with high levels of thematic relevance are nevertheless sensitive to exposure reduction as a means for improving the acceptance of base stations in their neighborhood. This underlines the value of exposure reduction for the acceptance of radio frequency electromagnetic field communication technologies. PMID:28594366

In environmental surveys, risk perception may be a source of bias when information on health outcomes is reported using questionnaires. Using the data from a survey carried out in the largest chipboard industrial district in Italy (Viadana, Mantova), we devised a score of health risk perception and described its determinants in an adult population. In 2006, 3697 parents of children were administered a questionnaire that included ratings on 7 environmental issues. Items dimensionality was studied by factor analysis. After testing equidistance across response options by homogeneity analysis, a risk perception score was devised by summing up item ratings. Factor analysis identified one latent factor, which we interpreted as health risk perception, that explained 65.4% of the variance of five items retained after scaling. The scale (range 0-10, mean ± SD 9.3 ± 1.9) had a good internal consistency (Cronbach's alpha 0.87). Most subjects (80.6%) expressed maximum risk perception (score = 10). Italian mothers showed significantly higher risk perception than foreign fathers. Risk perception was higher for parents of young children, and for older parents with a higher education, than for their counterparts. Actual distance to major roads was not associated with the score, while self-reported intense traffic and frequent air refreshing at home predicted higher risk perception. When investigating health effects of environmental hazards using questionnaires, care should be taken to reduce the possibility of awareness bias at the stage of study planning and data analysis. Including appropriate items in study questionnaires can be useful to derive a measure of health risk perception, which can help to identify confounding of association estimates by risk perception.

A suitable level of social perception about flood risk and awareness of Civil Protection Plans are critical to minimize disasters and damages due to flash floods. In order to improve risk perception, awareness and, as a result, the effectiveness of Civil Protection Plans, it is often required the implementation of communication plans. This research proposes a guide recommendation framework to enhance local population preparedness, prevention and response when a flash flood occurs. The research setting was a village (Navaluenga) located in Central Spain with 2,027 inhabitants. It is crossed by the Alberche river and Chorreron stream (both tributaries of the Tagus river), which are prone to flash floods. In a first phase, we assessed citizens' flash-flood risk perception and level of awareness regarding some key variables of the Civil Protection Plan. To this end, a questionnaire survey was designed and 254 adults, a sample representing roughly 12% of the population census, were interviewed. Responses were analysed, comparing awareness regarding preparedness and response actions with those previously defined in the Civil Protection Plan. In addition, we carried out a latent class cluster analysis aimed at identifying the different groups present among the respondents. Next, a risk communication plan was designed and implemented. It aimed to improve the understanding of flood risk among local people; and it comprises briefings, quiz-answers, contests of stories and flood images and intergenerational workshops. Finally, participants in the first phase were reached again and a new survey was performed. The results derived from these second questionnaires were statistically treated using the same approach of the first phase. Additionally, a t-test for paired samples and Pearson Chi-Square test was implemented in order to detect possible improvements in the perception and awareness. Preliminary results indicate that in Navaluenga there is a low social perception of flood risk and a low level of awareness regarding the Civil Protection Plan. In the social context of the Iberian Peninsula, where climate change models indicate an increase in extreme weather events and, consequently, high exposure and vulnerability to flash floods, the implementation of appropriately designed communication strategies is critical to improve the resilience of urban areas in order to cope with this risk.

Mother-daughter communication about sex: the influence of authoritative parenting style.

Parent-child communication about sex has been shown to delay sexual activity and increase contraceptive and condom use. The influence of authoritative parenting style and mothers' perception of daughters' risk on communication about sex was examined in this study. Mothers in a random sample (n=283) with daughters aged 9-15 years were mailed surveys asking about communication with their daughters regarding 11 sex-related topics. Multivariate linear regression was used to assess the influence of authoritative parenting style and mothers' perceptions of risk on the number of topics communicated about and age of the daughter at time of communication for a variety of sexual health communication topics. Authoritative parenting style was related to the number of topics communicated about and was a predictor of age of daughter at the time of communication about sexual intercourse, menstruation, dating/relationships, sexually transmitted diseases (STDs), HIV/AIDS, alcohol, contraceptives, and abstinence, while perceptions of risk were not significant influencers of age at the time of communication for any topics. This research points to the importance of parenting style in determining the timing of parent-child communication about sexual and other risk behaviors.

Predicting Future Reading Problems Based on Pre-reading Auditory Measures: A Longitudinal Study of Children with a Familial Risk of Dyslexia

PubMed Central

Law, Jeremy M.; Vandermosten, Maaike; Ghesquière, Pol; Wouters, Jan

2017-01-01

Purpose: This longitudinal study examines measures of temporal auditory processing in pre-reading children with a family risk of dyslexia. Specifically, it attempts to ascertain whether pre-reading auditory processing, speech perception, and phonological awareness (PA) reliably predict later literacy achievement. Additionally, this study retrospectively examines the presence of pre-reading auditory processing, speech perception, and PA impairments in children later found to be literacy impaired. Method: Forty-four pre-reading children with and without a family risk of dyslexia were assessed at three time points (kindergarten, first, and second grade). Auditory processing measures of rise time (RT) discrimination and frequency modulation (FM) along with speech perception, PA, and various literacy tasks were assessed. Results: Kindergarten RT uniquely contributed to growth in literacy in grades one and two, even after controlling for letter knowledge and PA. Highly significant concurrent and predictive correlations were observed with kindergarten RT significantly predicting first grade PA. Retrospective analysis demonstrated atypical performance in RT and PA at all three time points in children who later developed literacy impairments. Conclusions: Although significant, kindergarten auditory processing contributions to later literacy growth lack the power to be considered as a single-cause predictor; thus results support temporal processing deficits' contribution within a multiple deficit model of dyslexia.

Engels, Melanie J.

2015-01-01

Background: High-alert medications pose a greater risk of causing significant harm to patients if used in error. The Joint Commission requires that hospitals define institution-specific high-alert medications and implement processes to ensure safe medication use. Method: Nursing, pharmacy, and prescribers were asked to voluntarily complete a 34-question survey to assess their knowledge, experience, and perceptions regarding high-alert medications in an academic hospital. Results: The majority of respondents identified the organization’s high-alert medications, the consequences of an error involving a high-alert medication, and the reversal agent. Most of the risk-reduction strategies within the institution were viewed as being effective by respondents. Forty-five percent of the respondents utilized a high-alert medication in the previous 24 hours. Only 14.2% had experienced an error with a high-alert medication in the previous 12 months, with 46% being near misses. The survey found the 5 rights for medication administration were not being utilized consistently. Respondents indicated that work experience or hospital orientation is the preferred learning experience for high-alert medications. Conclusions: This study assessed all disciplines involved in the medication use process. Perceptions about high-alert medications differ between disciplines. Ongoing discipline-specific education is required to ensure that individuals accept accountability in the medication use process and to close knowledge gaps on high-alert medications and risk-reduction strategies.

Describe relationships between self-reported personal demographics or familial characteristics and psychosocial outcomes (Patient Reported Outcome Measurement Information System Global Health, Impact of Event Scale-Revised [pancreatic cancer risk-related distress], cancer risk perception, and cancer worry) in participants with inherited or familial pancreatic cancer risk. A multisite cross sectional survey of adults with elevated pancreatic cancer risk based on family history. All variables were summarized with descriptive statistics. To assess univariate associations, t test and chi-square/Fisher's exact test were used, and backward model selection was used in multivariable analysis. Respondents (N = 132) reported moderate to high frequency of cancer worry and 59.3% perceived a 50% or more perceived lifetime risk for pancreatic cancer, which far exceeds objective risk estimates. Cancer worry was associated with female gender (P = .03) and pancreatic cancer risk specific distress (P = .05). Higher-risk perception was associated with having a high school education or less (P = .001), higher distress (P = .02), and cancer worry (P = .008) and family cancer death experience (P = .02). Higher distress was associated with experience as a caregiver to a seriously ill family member in the past 5 years (P = .006). Individuals with inherited or familial pancreatic cancer risk experience cancer worry, distress, and have increased risk perception, particularly in the period following caring for a loved one with cancer. Routine evaluation of distress in this setting, as well as the development of supportive care resources, will help support patients living with risk for pancreatic cancer.

The application of e-health technology to the field of substance use disorders is at a relatively early stage, and methodological quality is still variable. Few have explored the extent of utilization of communication technology in exploring risk perception by patients enrolled in substance abuse services. The Overdose RIsk InfOrmatioN (ORION) project is a European Commission funded programme, aimed to develop and pilot an e-health psycho-educational tool to provide information to drug using individuals about the risks of suffering a drug overdose. In this article, we report on phase 1 (risk estimation), phase 2 (design), and phase 3 (feasibility) of the ORION project. The development of ORION e-health tool underlined the importance of an evidence-based intervention aimed in obtaining reliable evaluation of risk. The ORION tool supported a decision making process aimed at influencing the substance users' self-efficacy and the degree to which the substance users' understand risk factors. Therefore, its innovative power consisted in translating risks combination into a clear estimation for the user who will then appear more likely to be interested in his/her risk perception. Exploratory field testing and validation confirmed the next stage of evaluation, namely, collection of routine patient samples in study clinics. The associations between risk perception of overdose, engagement with the ORION tool and willingness to alter overdose risk factors, in a clinical setting across various EU member states will further confirm the ORION tool's generalisability and effectiveness.

Considerable attention has been afforded to analyzing the content of and assessing consumers' reaction to print direct-to-consumer drug ads, but not so for televised ads. To determine whether advertisements with different risk severity and risk presentation would significantly affect viewers' (1) recall of information contained in the advertisement, (2) evaluation of the advertisement, and (3) perceptions of the advertised product's risks. Data were collected from a sample of 135 first-year pharmacy students at a Midwestern college of pharmacy. After viewing 1 of the 6 advertisements designed for this study, participants were asked to complete a self-administered survey. Chi-square and analysis of variance were used to analyze the data. A 2x3 between subjects design was used to test the effects of 2 levels of risk severity (high- vs low-risk severity) and 3 levels of risk presentation (original ad containing integrated risk message, deintegrated risk message/dual modality using male voice-over, deintegrated risk message/dual modality using female voice-over). Results of analysis of variance procedures revealed that deintegrating risk information by placing it at the end of the advertisement and the use of captions in addition to oral messages (dual modality) (1) improved the recall of general and specific side effect information, (2) led to a perception that the advertisement had greater informational content, (3) resulted in lower Advertisement Distraction, and (4) lessened cognitive and affective aspects of information overload for the advertisement containing the high-risk severity medication. However, this pattern of findings was not found for the low-risk severity medication. Alternative methods for presenting risk information in direct-to-consumer ads affected some aspects of information recall and advertisement evaluation, but were not shown to affect risk perceptions regarding the advertised products.

The purpose of this study was to evaluate the ability of men who have sex with men (MSM) testing for HIV at commercial sex venues to assess the following: their candidacy for pre-exposure chemoprophylaxis (PrEP) as defined by meeting entry criteria for the iPrEx (Iniciativa Profilaxis Pre-Exposición) phase III clinical trial of PrEP, and their perception of their own HIV risk and candidacy for PrEP. Interviewers surveyed 629 MSM at three NYC commercial sex venues from June 2011 through June 2012. Questions focused on demographics, sexual activity, and drug use in the three months prior to testing, as well as perceived risk of HIV acquisition and perceived candidacy for PrEP use. Data were analyzed by Chi square and Fisher's exact test. Results show that a majority of clients (80.3%) met entry criteria for the iPrEX. Most of these men (78.0%), however, did not perceive their risk to be significant enough to warrant PrEP use (P=.000). Factors were identified which associated with a risk perception that correlated with eligibility for iPrEX.

Healthy individuals' perspectives on clinical research protocols and influences on enrollment decisions.

Understanding the perspectives of healthy individuals is important ethically and for the advancement of science. We assessed perceptions of risk associated with research procedures, comparing views of healthy individuals with and without experience in clinical research, and the respondents' reported willingness to volunteer. Semistructured interviews and written surveys were conducted. Study participants were healthy individuals, half of whom were currently enrolled in clinical research and half of whom had no prior experience in clinical research. Participants were queried regarding seven "minimal risk" or "greater than minimal risk" protocol vignettes with procedures of three types: routine diagnostic tests, more burdensome (i.e., more effort or potential harm) diagnostic tests, and pharmacologic interventions. Views of influences on enrollment decisions were also assessed. Most healthy individuals indicated that protocols with more burdensome or pharmacologic interventions were very risky (59%, 58%), as opposed to routine diagnostic test procedures (32%). Respondents' willingness to enroll in protocols varied by type of protocol (p value < .001) and was inversely correlated with risk assessments (regression coefficients from GEE = -0.4; -0.5; -0.7). The odds of healthy individuals with research experience expressing strong willingness to enroll in the depicted protocols were twice the odds of healthy individuals without research experience expressing the same level of willingness (OR = 2.0 95% CI: [1.1, 3.9]). Respondents did not assign risk categories as institutional review boards (IRBs) would, as indicated by low agreement (26%) between respondent and expert opinion on minimal risk protocols. Perceptions of procedure risk appear to influence healthy individuals' willingness to enroll in protocols. Participants with experience in clinical research were far more likely to express willingness to enroll, a finding with important scientific and ethical implications. The lack of alignment between healthy individuals' views of protocol risk and IRB categorization warrants further study.

We sought to determine whether individuals' risk perceptions and efficacy beliefs could be used to meaningfully segment audiences to assist interventions that seek to change HIV-related behaviors. A household-level survey of individuals (N=968) was conducted in 4 districts in Malawi. On the basis of responses about perceptions of risk and beliefs about personal efficacy, we used cluster analysis to create 4 groups within the risk perception attitude framework: responsive (high risk, strong efficacy), avoidance (high risk, weak efficacy), proactive (low risk, strong efficacy), and indifference (low risk, weak efficacy). We ran analysis of covariance models (controlling for known predictors) to determine how membership in the risk perception attitude framework groups would affect knowledge about HIV, HIV-testing uptake, and condom use. A significant association was found between membership in 1 or more of the 4 risk perception attitude framework groups and the 3 study variables of interest: knowledge about HIV (F8, 956=20.77; P<.001), HIV testing uptake (F8, 952=10.91; P<.001), and condom use (F8, 885=29.59; P<.001). The risk perception attitude framework can serve as a theoretically sound audience segmentation technique that can be used to determine whether messages should augment perceptions of risk, beliefs about personal efficacy, or both.

Municipal home care workers provide high-quality services to an increasing proportion of elderly people living in private homes. The work environments and working conditions of these workers vary to a great extent, implying rapid priority-making among both employers and employees to ensure that the work can be performed in a safe way. This study aims to examine home care workers' perceptions of health, risks, working conditions, and risk management within their organization. The study was based on cross-sectional data collected from home care service staff in a municipality in the north of Sweden. Nursing assistants and care aides ( n  = 133) replied to a self-administered questionnaire. Descriptive statistics and between-group differences were analysed. Home care work was perceived to require high levels of professional skill and ingenuity, a good psychosocial work situation, but required a high physical workload. The general health, the capacity and self-efficacy of the staff in relation to work were good. Difficulty in performing risk assessments and following safety regulations due to lack of time, equipment, and information were identified. There is a need to increase participation in risk assessments among the staff, improve management support, structures, and cooperation with other divisions of the social services and the medical care organizations.

Are non-native plants perceived to be more risky? Factors influencing horticulturists' risk perceptions of ornamental plant species.

Horticultural trade is recognized as an important vector in promoting the introduction and dispersal of harmful non-native plant species. Understanding horticulturists' perceptions of biotic invasions is therefore important for effective species risk management. We conducted a large-scale survey among horticulturists in Switzerland (N = 625) to reveal horticulturists' risk and benefit perceptions from ornamental plant species, their attitudes towards the regulation of non-native species, as well as the factors decisive for environmental risk perceptions and horticulturists' willingness to engage in risk mitigation behavior. Our results suggest that perceived familiarity with a plant species had a mitigating effect on risk perceptions, while perceptions of risk increased if a species was perceived to be non-native. However, perceptions of the non-native origin of ornamental plant species were often not congruent with scientific classifications. Horticulturists displayed positive attitudes towards mandatory trade regulations, particularly towards those targeted against known invasive species. Participants also expressed their willingness to engage in risk mitigation behavior. Yet, positive effects of risk perceptions on the willingness to engage in risk mitigation behavior were counteracted by perceptions of benefits from selling non-native ornamental species. Our results indicate that the prevalent practice in risk communication to emphasize the non-native origin of invasive species can be ineffective, especially in the case of species of high importance to local industries and people. This is because familiarity with these plants can reduce risk perceptions and be in conflict with scientific concepts of non-nativeness. In these cases, it might be more effective to focus communication on well-documented environmental impacts of harmful species.

Ramey, Sandra L

2003-05-01

The relationship among cardiovascular disease (CVD) morbidity, risk factors (including stress), and the perception of health among male law enforcement officers (LEOs) compared to men in the general population were examined in this study. Self reported prevalence of CVD and CVD risk factors among currently employed male LEOs from nine states (n = 2,818) were compared to those of other men in the same states (n = 9,650 for CVD risk factors, n = 3,147 for CVD prevalence). Perceived stress in LEOs was assessed to determine if it affected the relationship between CVD prevalence and CVD risk factors. Cross tabulated simple percentages showed CVD was less prevalent in the LEO group than among the general population. The best predictor variables for CVD were perceived stress, time in the profession, and hypertension. The LEO group had greater prevalence of hypercholesterolemia, overweight, and tobacco use than the general population. However, a greater percentage of LEOs perceived their health as "good to excellent" compared to men in the general population. Using multivariate analysis of variance (MANOVA) it was determined that perceived stress was associated with CVD in the LEO group and three CVD risk factors (i.e., cholesterol, hypertension, physical activity) were significantly affected by perceived stress. Among susceptible officers, stress may contribute to CVD development as well as potentiate several CVD risk factors. However, an apparent lack of association exists between perception of general health and CVD risk in LEOs.

Perinatal HIV transmission disproportionately affects African American, Latina and potentially Hmong women in the United States. Understanding racially and ethnically diverse women's perceptions of and experiences with perinatal health care, HIV testing and HIV/AIDS may inform effective health communications to reduce the risk of perinatal HIV transmission among disproportionate risk groups. We used a qualitative descriptive research design with content analysis of five focus groups of African American, Caucasian, Hmong and Latina women of reproductive age with low socioeconomic status distinguished by their race/ethnicity or HIV status. A purposive stratified sample of 37 women shared their health-care experiences, health information sources and perceptions of HIV testing and HIV/AIDS. Women's responses highlighted the importance of developing and leveraging trusted provider and community-based relationships and assessing a woman's beliefs and values in her sociocultural context, to ensure clear, consistent and relevant communications. Perinatal health communications that are culturally sensitive and based on an assessment of women's knowledge and understanding of perinatal health and HIV/AIDS may be an effective tool for health educators addressing racial and ethnic disparities in perinatal HIV transmission.

An integrated benefit-risk analysis aims to give guidance in decision situations where benefits do not clearly prevail over risks, and explicit weighing of benefits and risks is thus indicated. The BEPRARIBEAN project aims to advance benefit-risk analysis in the area of food and nutrition by learning from other fields. This paper constitutes the final stage of the project, in which commonalities and differences in benefit-risk analysis are identified between the Food and Nutrition field and other fields, namely Medicines, Food Microbiology, Environmental Health, Economics and Marketing-Finance, and Consumer Perception. From this, ways forward are characterized for benefit-risk analysis in Food and Nutrition. Integrated benefit-risk analysis in Food and Nutrition may advance in the following ways: Increased engagement and communication between assessors, managers, and stakeholders; more pragmatic problem-oriented framing of assessment; accepting some risk; pre- and post-market analysis; explicit communication of the assessment purpose, input and output; more human (dose-response) data and more efficient use of human data; segmenting populations based on physiology; explicit consideration of value judgments in assessment; integration of multiple benefits and risks from multiple domains; explicit recognition of the impact of consumer beliefs, opinions, views, perceptions, and attitudes on behaviour; and segmenting populations based on behaviour; the opportunities proposed here do not provide ultimate solutions; rather, they define a collection of issues to be taken account of in developing methods, tools, practices and policies, as well as refining the regulatory context, for benefit-risk analysis in Food and Nutrition and other fields. Thus, these opportunities will now need to be explored further and incorporated into benefit-risk practice and policy. If accepted, incorporation of these opportunities will also involve a paradigm shift in Food and Nutrition benefit-risk analysis towards conceiving the analysis as a process of creating shared knowledge among all stakeholders.

Ju, Chengting; Ji, Ming; Lan, Jijun; You, Xuqun

2017-12-01

Optimism bias is a crucial feature of risk perception that leads to increased risk-taking behaviour, which is a particularly salient issue among pilots in aviation settings due to the high-stakes nature of flight. The current study sought to address the roles of narcissism and promotion focus on optimism bias in risk perception in aviation context. Participants were 239 male flight cadets from the Civil Aviation Flight University of China who completed the Narcissistic Personality Inventory-13, the Work Regulatory Focus Scale, and an indirect measure of unrealistic optimism in risk perception, which measured risk perception for the individual and the risk assumed by other individuals performing the same task. Higher narcissism increased the likelihood of underestimating personal risks, an effect that was mediated by high promotion focus motivation, such that high narcissism led to high promotion focus motivation. The findings have important implications for improving the accuracy of risk perception in aviation risks among aviators. © 2016 International Union of Psychological Science.

Children in health research: a matter of trust.

PubMed

Woodgate, Roberta L; Edwards, Marie

2010-04-01

Central to the involvement of children in health research is the notion of risk. In this paper we present one of the factors, a matter of trust, that shaped Canadian parents' and children's perceptions and assessments of risk in child health research. Part of a larger qualitative research study, 82 parents took part an in-depth qualitative interview, with 51 parents having children who had participated in health research and 31 having children with no research history. 51 children ranging from 6 to 19 years of age were also interviewed, with 28 having a history of participation in child health research and 23 having no history. Children also took part in 3 focus groups interviews. Themes emerged through a grounded theory analysis of coded interview transcripts. The presence or absence of trust was not only perceived by parents and children as a contributing factor to involving children in health research, but also shaped their perceptions and assessments of risk. Three interrelated subthemes identified were: (1) relationships of trust; (2) placing trust in symbols of authority; and (3) the continuum of trust. Our study reinforces that trust is an important factor when parents assess risk in child health research and shows that children use the language of trust in relation to risk. More discussion regarding trust in training researchers is warranted given the trust in researchers and institutions evident in this study. We also recommend further study of the continuum of trust in child health research.

News, music videos and action movie exposure and adolescents' intentions to take risks in traffic.

This study explored the relationship between adolescents' viewing of specific television genres (action movies, news and music videos) and the intention to take risks in traffic. Participants were 2194 adolescent boys and girls who completed a questionnaire on television viewing, risk perception and the intention to speed and drive after consuming alcohol. As hypothesized, more news viewing was associated with a higher perceived risk of drunk driving and speeding. More music video viewing, on the other hand, was negatively associated with the assessment of the dangers of speeding and driving under the influence of alcohol. Girls regarded speeding and drunk driving as more dangerous than boys did. Contrary to our hypotheses, action movie viewing did not make a significant contribution to our models. Both news and music video viewing were indirectly, via risk perception, related to the intention to drive risky. The more dangerous a particular behavior was perceived to be, the less likely respondents intended to exhibit this behavior in the future.

Polycyclic aromatic hydrocarbons (PAHs) are environmental pollutants that cause cancers in humans. Exposure results from incomplete burning of organic materials. Grilled meat vendors are occupationally exposed to PAHs in smoke from continuously burning charcoal and meat, which may have chance to get cancer. Individual risk perception is a critical antecedent of preventive behavior However relatively little is known about the cancer risk perception and preventive behaviors among grilled meat vendors. The present study aimed to examine cancer risk perception and preventive behaviors and factors associated with preventive behaviors among grilled meat vendors in Bangkok, Thailand. A cross-sectional survey was used in the present study. The subjects consisted of 40 males and 82 females grilled meat vendors who conducted their jobs at Victory Monument, Bang Lumpoo, Pratunam, Jakkawat or Patumwan. They were interviewed regarding cancer risk perception and preventive behaviors. Multiple logistic regression analysis was used to analyze data. Average cancer risk perception score was 23.3 +/- 3.3 out of 32. About 79.5% of the subjects had high risk perception. The prevalence of good preventive behaviors was 86.1%. The three most frequent preventive behaviors among the subjects during grilling meat were using good quality charcoal (65.6%), ventilation fan (41.0%) and wearing long sleeves shirt (36.1%). Only 10.7% always used gloves. Multiple logistic regression analysis showed 2 factors were independently associated with preventive behaviors: educational level and risk perception. The subjects who had higher educational level or risk perception were more likely to develop better behaviors than those who had a lower educational level and perception (p < 0.05). In conclusion, the present study found that the educational background and cancer risk perception were associated with preventive behaviors among grilled meat vendors. To improve the preventive behaviors among grilled meat vendors, interventions focusing on cancer risk perceptions and considering educational background among target group are recommended.
