Interventions Using Heart Age for Cardiovascular Disease Risk Communication: Systematic Review of Psychological, Behavioral, and Clinical Effects.

BackgroundCardiovascular disease (CVD) risk communication is a challenge for clinical practice, where physicians find it difficult to explain the absolute risk of a CVD event to patients with varying health literacy. Converting the probability to heart age is increasingly used to promote lifestyle change, but a rapid review of biological age interventions found no clear evidence that they motivate behavior change.ObjectiveIn this review, we aim to identify the content and effects of heart age interventions.MethodsWe conducted a systematic review of studies presenting heart age interventions to adults for CVD risk communication in April 2020 (later updated in March 2021). The Johanna Briggs risk of bias assessment tool was applied to randomized studies. Behavior change techniques described in the intervention methods were coded.ResultsFrom a total of 7926 results, 16 eligible studies were identified; these included 5 randomized web-based experiments, 5 randomized clinical trials, 2 mixed methods studies with quantitative outcomes, and 4 studies with qualitative analysis. Direct comparisons between heart age and absolute risk in the 5 web-based experiments, comprising 5514 consumers, found that heart age increased positive or negative emotional responses (4/5 studies), increased risk perception (4/5 studies; but not necessarily more accurate) and recall (4/4 studies), reduced credibility (2/3 studies), and generally had no effect on lifestyle intentions (4/5 studies). One study compared heart age and absolute risk to fitness age and found reduced lifestyle intentions for fitness age. Heart age combined with additional strategies (eg, in-person or phone counseling) in applied settings for 9582 patients improved risk control (eg, reduced cholesterol levels and absolute risk) compared with usual care in most trials (4/5 studies) up to 1 year. However, clinical outcomes were no different when directly compared with absolute risk (1/1 study). Mixed methods studies identified consultation time and content as important outcomes in actual consultations using heart age tools. There were differences between people receiving an older heart age result and those receiving a younger or equal to current heart age result. The heart age interventions included a wide range of behavior change techniques, and conclusions were sometimes biased in favor of heart age with insufficient supporting evidence. The risk of bias assessment indicated issues with all randomized clinical trials.ConclusionsThe findings of this review provide little evidence that heart age motivates lifestyle behavior change more than absolute risk, but either format can improve clinical outcomes when combined with other behavior change strategies. The label for the heart age concept can affect outcomes and should be pretested with the intended audience. Future research should consider consultation time and differentiate between results of older and younger heart age.International Registered Report Identifier (IRRID)NPRR2-10.1101/2020.05.03.20089938

Enhancing Adolescent Risk Perception of Electronic Cigarette Use.

Adolescent electronic cigarette use has been steadily increasing since first being introduced commercially in 2007. The aim of this pilot study was to determine if adolescents who watched an educational video during a wellness visit would increase their perception of risk related to electronic cigarette use. Seventy-nine adolescents participated and were randomly assigned to the intervention (n = 40) or control (n = 39) group. Results included risk perception, perceived benefit, and provider discussion about electronic cigarettes. There was no statistical difference between intervention and control groups for electronic cigarette risk or perceived electronic cigarette benefit. Adolescents who watched the video intervention compared to those who did not watch a video intervention were significantly more likely to report having discussed electronic cigarettes with their provider (p < .001). Watching a video intervention on electronic cigarettes increased the likelihood of a reported discussion between provider/patient about electronic cigarettes but did not increase risk perception or decrease perceived benefit of electronic cigarettes. Utilizing video education is one tool that could potentially be used to augment provider education during wellness visits.

How can we test plastic pollution perceptions and behavior? A feasibility study with Danish children participating in “the Mass Experiment”

Research suggests that behavior change programs can be fast and cost-effective solutions to plastic pollution alongside traditional environmental policy-making. Furthermore, encouraging change in perception and behavior can be a tool to change consumption and waste handling towards increased circularity, which is of high concern in the EU. Beyond knowledge, predictors of pro-environmental behavior include concern, social norms, nature-connectedness, identity and self-efficacy. Citizen Science (CS) as a way to raise awareness and potentially change behavior show promise within plastic litter monitoring. We tested the feasibility of evaluating a nation-wide citizen science intervention, ‘the Mass Experiment’ (ME), with school students (age 7-16) in Denmark. With more than 57,000 students signed up for ME, this is to our knowledge one of the largest CS activity on plastic debris targeting young people. As an addition to the core CS activity we developed a voluntary and anonymous questionnaire to study the perceptions and behaviors of the students. We hypothesized that the intervention would increase risk perception, self-efficacy and empowerment as well as self-reported actions. Through 931 pre-surveys and 838 post-surveys aggregated at the team level (n = 48), we found that the intervention had no significant overall effect on team, risk-perception, pro-environmental behaviors, nor self-efficacy or empowerment. However, unexpected patterns emerged for age effects, potentially advising some caution over the design of such CS activities particularly for younger children. We discuss methodological limitations, the high baseline for nearly all variables, the Danish context and the intervention itself and make recommendations for studying future CS interventions.

Emotional Appeals, Climate Change, and Young Adults: A Direct Replication of Skurka et al. (2018)

AbstractThere is much need to verify the robustness of published findings in the field of communication—particularly regarding the effects of persuasive emotional appeals about social issues. To this end, we present the results from a preregistered, direct replication of C. Skurka, J. Niederdeppe, R. Romero-Canyas, and D. Acup (2018). The original study found that a threat appeal about climate change can increase risk perception and activism intentions and that a humor appeal can also increase activism intentions with a large sample of young adults. Using the same stimuli, measures, and experimental design with a similar sample, we fail to replicate these main effects. We do, however, replicate age as a moderator of humor’s effect on perceived risk, such that the humor appeal only persuaded emerging adults (ages 18–21.9). We consider several explanations for our discrepant findings, including the challenges (and opportunities) that persuasion researchers must navigate when communicating about rapidly evolving social issues.

Influence of package colour, branding and health warnings on appeal and perceived harm of cannabis products among respondents in Canada and the US

‘Plain packaging’ and health warnings can reduce appeal and increase risk perceptions of tobacco products. This study tested the effect of health warnings and restricted brand imagery on perceptions of cannabis products. Participants in Canada and the US (n = 45,378) were randomized to view packages of three cannabis brands in 2019. A 3 (health warning) x 4 (brand imagery) between-group factorial experimental design was used. Health warning conditions were: none, Canadian or US warning. The Canadian warning conditions had three messages counterbalanced across brands: pregnancy, adolescent risk, and impaired driving. The US warning mentioned the same broad risk categories. The four branding conditions ranged from packages displaying no brand imagery and uniform colours—‘plain packaging’—to full brand imagery. Regression tested differences between conditions on product appeal, perceived harm, and free recall of warning messages. Overall, full branding and plain packaging were rated the most and least appealing, respectively (p < 0.001). Products were rated as significantly less harmful when they had a white background with no or limited branding versus a coloured background (p ≤ 0.01). Products with health warnings were rated significantly less appealing and more harmful than those with no warning (p < 0.001). Message recall was significantly higher for Canadian versus US health warnings, and for the US warning versus no warning (p < 0.001). Message recall was greater among those who saw plain versus fully branded packages for two of the three warning messages (p < 0.01). Prominent health warnings and restrictions on brand imagery may be warranted in jurisdictions considering non-medical cannabis legalization.

Experience is not enough: A dynamic explanation of the limited adaptation to extreme weather events in public organizations

This study advances theory articulating the micro-level processes behind public organization adaptation to extreme weather. It tackles a persistent puzzle about the limited adaptation to extreme weather among public organizations: why does adaptation remain deficit after public organizations have experienced repeated extreme weather and some catastrophic consequences? We develop a computational agent-based model that integrates extant theory and data from semi-structured interviews of U.S. public transit agency managers, and use the model to investigate how micro-level cognition and behavior interact with environmental constraints to facilitate or impede the diffusion of adaptation. We articulate in greater detail how experience with influential extreme weather events matters to adaptation, highlighting that such experience is insufficient for adaptation to occur. A key insight is that the potential benefits from both increased risk perception and additional financial resources stemming from disaster- or non-disaster-induced opportunities can be underutilized, absent effective coupling between heightened risk perception and availability of resources that creates windows for adaptation. Using this insight, we further identify managerial and policy interventions with maximum leverage to promote adaptation to extreme weather in public organizations. The experiments show that slowing risk perception decay and synchronizing opportunities with extreme weather occurrences can stimulate adaptation.

Age-varying time trends in cannabis- and alcohol-related risk perceptions 2002–2019

BackgroundAlcohol- and cannabis-related risk perceptions are strong predictors of use behavior. Studies suggest that attitudes toward cannabis are becoming increasingly permissive, however studies have yet to comprehensively a) compare time trends in cannabis-related attitudes to those of other commonly used substances, such as alcohol, and b) test whether trends significantly differ by age. MethodPublic access data from the National Study on Drug Use and Health from 2002 to 2019 were used (N = 1,005,421). Structural Equation Models tested whether study year (linear trend), was associated with alcohol- and cannabis-related risk perceptions (correlated outcomes), and whether age (adolescence [12–17], emerging adulthood [18–25], adulthood [26–35], middle adulthood [36–49], and older adulthood [50+]) moderated time trends. Sex, race/ethnicity, and use frequency were covaried. ResultsThe linear trend of study year was associated with decreased cannabis-related risk perceptions (p < .001). There was also a significant interaction of age by study year for cannabis-related risk perceptions, such that adults, emerging adults, and middle adults had the largest decrease in attitudes over time. For alcohol-related risk perceptions, the linear trend of study year was significantly associated with increased risk perceptions (p = .001), but the interaction of time by age was non-significant; alcohol-related effects were extremely small (b < 0.01). ConclusionsFindings suggest that cannabis-related risk perceptions are becoming more permissive with time across ages, but particularly in adults, emerging adults, and middle adults. In contrast, alcohol-related risk perceptions have stayed relatively stable over time, with only negligible increases. Findings underscore the importance of targeting permissive cannabis-related attitudes via prevention efforts.

The role of fortitude, loneliness, and depression in the association between risk perception of contracting COVID-19 and life satisfaction: serial mediation analysis

Recently, the COVID-19 pandemic has been found to have a negative impact on both physical wellbeing and mental health. Increased risk perception of contracting the virus has been associated with adverse psychological outcomes and reduced life satisfaction. However, susceptibility to psychological distress is influenced by personality-related characteristics. This study focuses on fortitude as a potential protective factor. The aim of this study is to investigate the parallel and serial mediating roles of fortitude, loneliness, and depression in the relationship between risk perception and life satisfaction. The participants were young adults ( N = 337) who have completed five self-report questionnaires: University of California Los Angeles Loneliness Scale, Centre for Epidemiological Studies Depression Scale, Fortitude Questionnaire, Satisfaction with Life Scale, and COVID-19 Risk Perception Scale. Descriptive statistics were generated, and structural equation modelling was used to examine the parallel and serial mediating roles of loneliness, depression, and fortitude. Positive associations were found between risk perception and loneliness and depression, and fortitude was found to mediate the relationship between risk perception and life satisfaction, between loneliness and life satisfaction, and between depression and life satisfaction. The overall serial mediation was also found to be significant, thereby supporting the hypothesis that those who perceive themselves to be at a risk of contracting COVID-19 have higher loneliness scores, which in turn is associated with higher depression scores. These findings confirm that fortitude is a salient protective factor and suggest that improving the perception of the ability to manage the risk of infection can enhance psychological wellbeing.

Fear Language in a Warning Is Beneficial to Risk Perception in Lower-Risk Situations.

The goal was to examine the effectiveness of fear language in the protective action recommendation of an emergency warning, which instructs people how to prepare and stay safe. Past work is limited because it has focused on describing the severity of the weather crisis, not improving the recommendation. Likewise, other research has examined fear appeals that overemphasize death, which leads to poor risk perceptions. In Experiment 1, the presence of fear language and second-person personal pronouns (i.e., "you") in a recommendation was manipulated. Experiment 2 examined how fear language and a hurricane changing in intensity influenced risk perceptions across three decision points. Experiment 1 suggested that fear language was more influential than a pronoun on risk perceptions. Experiment 2 suggested that fear language in a protective action recommendation was most impactful in the case of a hurricane decreasing in intensity. Protective action recommendations with fear language influence risk perceptions and behaviors. The magnitude of this influence is dependent on how people have categorized the hurricane (i.e., low vs. high risk). These results demonstrate that fear appeals in hurricane warnings can be useful, especially in cases when a low to medium risk event is still extremely dangerous. Likewise, these results demonstrate a need for caution, as fear appeals are not a "one size-fits-all" approach to increasing risk perceptions and should be used thoughtfully. Recommendations of when to use fear appeals in protective action recommendations are provided based on the present data.

Viral mitigation and the COVID-19 pandemic: factors associated with adherence to social distancing protocols and hygienic behaviour

Objective To investigate the factors associated with adherence to viral mitigation protocols during the COVID-19 pandemic. Design This epidemiological cross-sectional study examines adherence to behaviour in 4158 adults and its relationship with sources of information. Main outcome measures Adherence to social distancing protocols (SDPs) and adherence to hygienic behaviour (HB) recommendations. Results Individuals aged 18–30 reported lowest adherence to SDPs and HB. Alcohol consumption was associated with lower adherence. Increased risk perception, fear of infection and altruistic attitude were associated with greater adherence. Males, single and childless individuals reported lower adherence. Extroverts and urban residents reported lower adherence to SDPs, but not HB. In contrast to earlier stages of the pandemic, voluntary social distancing was associated with greater adherence to SDPs as opposed to rule-enforced social distancing. Regarding information obtainment, increased time spent acquiring information from recognised newspapers had the strongest favourable association with adherence. Relying on information from friends and family was associated with decreased adherence to SDPs. Sensitivity analyses replicated the findings, supporting the stability and robustness of the proposed models. Conclusion This study identifies factors associated with favourable and detrimental adherence behaviour along with substantial dissemination routes, presenting strategies that may be of utility towards fostering adherence to contemporaneously implemented mitigation protocols.

Parental Perspectives on Immunizations: Impact of the COVID-19 Pandemic on Childhood Vaccine Hesitancy.

Childhood vaccine hesitancy has been studied extensively before the COVID-19 pandemic. The pandemic presented new barriers to pediatric vaccinations. Furthermore, the development of COVID-19 vaccines has complicated factors underlying vaccine hesitancy. We performed a cross-sectional mobile phone-based survey at Children’s Hospital Los Angeles querying parents regarding perspectives on vaccines before and during the pandemic. Our primary aim was to understand the impact of the pandemic on routine childhood vaccine hesitancy. Secondarily, we examined intent to vaccinate, COVID-19 vaccine hesitancy, and key contributing demographic factors. Among 252 participants, we found overall increased childhood vaccine hesitancy (p = 0.006), increased risk perception (p = 0.006), and unchanged vaccine confidence during the COVID-19 pandemic. Increased hesitancy did not translate into decreased intent to vaccinate with routine childhood vaccines or influenza vaccines. During the pandemic, households with higher income (50–99 K, > 100 K) correlated with decreased routine childhood vaccine hesitancy, while Hispanic ethnicity and African American race had increased risk perception. For COVID-19 vaccine hesitancy, households with higher income (> 100 K) correlated with decreased hesitancy, while non-White ethnicity and race had increased risk perception. We found that routine childhood vaccine hesitancy increased during the COVID-19 pandemic, mainly due to increased risk perception. Key contributing demographic factors behind both childhood vaccine hesitancy and COVID-19 vaccine hesitancy included household income and race. Understanding factors behind routine childhood vaccine hesitancy is crucial to maintaining pediatric vaccination rates and promoting vaccine confidence during and after the COVID-19 pandemic.

COVID-19 vaccination attitudes and intention among Quebecers during the first and second waves of the pandemic: findings from repeated cross-sectional surveys

ABSTRACT The availability of safe and effective vaccines is a major breakthrough in controlling the COVID-19 pandemic. However, the success of the COVID-19 vaccination campaign relies on high uptake by the public. We monitored Quebecers’ attitudes and intention toward COVID-19 vaccination during the first and second waves of the pandemic. Since March 2020, online surveys are conducted every week in Quebec (Canada) to assess Quebecers’ adherence to recommended public health measures (3,300 respondents are surveyed every week through an online panel; respondents are not invited to answer the survey for 21 days after responding). Ten items measured respondents’ attitudes and intentions regarding COVID-19 vaccination. Logistic regression models were used to identify determinants of intention to be vaccinated against COVID-19. Intention to be vaccinated against COVID-19 ranged from 76%-66% between the first and second waves. The proportion of undecided adults remained stable (12%). Being a man; being 60 years of age and over; having a university education level; having or living with someone with chronic medical conditions and increased risk perceptions of COVID-19 were the strongest predictors of COVID-19 vaccine acceptance in multivariate analysis. During data collection, COVID-19 vaccine supply was very limited. It was reassuring to note that intention to be vaccinated is the highest among older age groups that are prioritized to be vaccinated first. As more doses and vaccines will be available it will be important to enhance vaccine acceptance and uptake, especially among adults younger than 60 years of age and Quebecers with lower risk perceptions of COVID-19.

Rethinking Risk Perception and its Importance for Explaining Natural Hazard Preparedness Behavior.

Psychological theory suggests there is a positive association between risk perception and protective behavior. Empirical research has, however, found mixed support for the positive link between risk perception and protective behavior. One explanation for the inconsistent link is the way in which risk perception has been conceptualized and/or operationalized in past research. Specifically, few studies acknowledge differences in hazard severity and how it might affect risk perception and protective behavior. Past research has also tended to overlook the importance of emotional appraisal in relation to perceived hazard consequences. To address these inconsistencies in past research, 337 people living in a cyclone-prone location were recruited to participate in an online study. In this study, respondents were randomly presented with one of five hypothetical cyclone scenarios, which differed in objective severity. Respondents were also presented with a survey, which assessed risk perception, protective action perceptions (or coping appraisal), and intentions to perform short-term protective behaviors. As hypothesized, risk perception significantly increased preparedness intentions when controlling for hazard severity, hazard probability, and protective action perceptions. Moreover, the degree to which respondents associated negative emotions with predicted damage was also a relatively strong predictor of preparedness intentions. Overall, the findings support the theoretical link between risk perception and protective behavior and provide a new method of assessing risk perception in cross-sectional research. On a practical level, the results suggest that increasing risk perception should promote protective behavior in response to natural hazards.

How did travel mode choices change according to Coronavirus Disease 2019? Lessons from Seoul, South Korea

ABSTRACT The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic is believed to have substantially changed travel mode choices. While current urban transit policies and plans aim at higher public transit ridership, the negative perception that transit is unsafe increases in line with the spread of Coronavirus Disease 2019 (COVID-19) because of its higher risk in cases in which so-called 3C conditions are met: crowded areas, close-contact settings, and closed places. Thus, this study empirically examines how the perception of urban spaces changed by COVID-19 and how it influenced the choice of travel modes, accordingly, in the Seoul Metropolitan Area, South Korea. A structural equation model presents that changes in individual cognition and positive perception of policy changes during COVID-19 changes their perception of multi-use facilities negatively compared to before the COVID-19 outbreak. The negative perception is found to result in changes in travel mode choices by decreasing public transit ridership. Analytical findings show that intrinsic utility (i.e. risk perception) is revealed as a major determinant to understand travel mode choice. Also, in relation to the limitations of the current metropolitan transit system, the findings provide policy implications in the aspect of preventive measures and promoting micro-mobility for post-COVID-19 transit. Highlights The behavioural change under the pandemic is caused by fear of infection. Risk perception on public transit is affected negatively due to COVID-19. The increased risk perception leads to a reduction in public transit use. Risk perception is a major determinant to understand travel mode choice. Promoting micro-mobility will enhance the city's resilience during a pandemic.

Behaviour is the Key in a Pandemic: The Direct and Indirect Effects of COVID-19-Related Variables on Psychological Wellbeing.

The aim of this study was to investigate the potential role of three COVID-19-related variables (i.e., risk perception, knowledge, and behaviour) on four indices of pandemic-related mental health (i.e., anxiety, depression, loneliness, and hopelessness). In total, 337 participants completed four self-report questionnaires: selected subscales of the World Health Organisation's COVID-19 Behavioural Insights Tool, UCLA Loneliness Scale, State-Trait Anxiety Inventory-Trait Scale, Center for Epidemiologic Studies Depression Scale, and Beck Hopelessness Scale. In addition to descriptive statistics and intercorrelations, structural equation modelling was used to compare three models of the potential role (predictor or moderator/mediator) that the three abovementioned COVID-19-related variables could play in psychological wellbeing. The results showed high levels of psychological distress among the current sample. Generally, better knowledge of COVID-19 and engaging in protective behaviours were found to be related to lower levels of psychological distress, whereas increased risk perception was found to be associated with increased feelings of loneliness, anxiety, and depression. It was also found that behaviour mediated the effect of knowledge on psychological wellbeing, suggesting that while publicising information about COVID-19 remains necessary, providing the public with a means to engage in protective behaviours is central for promoting psychological wellbeing.

The Double Bind of Communicating About Zoonotic Origins: Describing Exotic Animal Sources of COVID-19 Increases Both Healthy and Discriminatory Avoidance Intentions.

Many novel diseases are of zoonotic origin, likely including COVID‐19. Describing diseases as originating from a diverse range of animals is known to increase risk perceptions and intentions to engage in preventative behaviors. However, it is also possible that communications depicting use of exotic animals as food sources may activate stereotypes of cultures at the origin of a disease, increasing discriminatory behaviors and disease stigma. We used general linear modeling and mediation analysis to test experimental data on communications about zoonotic disease origins from the critical first two months leading up to the declaration of a global pandemic. Results suggest that communications about potential familiar food origins (pigs) affected people's risk perceptions, health behaviors, and COVID‐19 stigma compared to more exotic food sources (e.g., snakes). Participants (N = 707) who read descriptions of exotic origins viewed the virus as riskier and reported stronger intentions to engage in preventative behaviors than those who read about familiar origins (pigs). However, reading exotic origin descriptions was also associated with stronger intentions to avoid Asian individuals and animal products. These results are critical for both theory and public policy. For theory, they are the first to experimentally demonstrate that zoonotic origin descriptions can impact intentions to engage in discriminatory behaviors for cultures viewed as the origin of a novel infectious disease. For policy, they offer clear, actionable insights on how to communicate about risks associated with a novel zoonosis while managing the potential impact on discriminatory behaviors and stigma.

Education and adaptive capacity: the influence of formal education on climate change adaptation of pastoral women

ABSTRACT Adaptive capacity is critical for understanding the climate resilience of social-ecological systems. A gendered lens is of particular importance as women are simultaneously one of the most vulnerable social groups to climate change and carry a significant adaptation burden. Individuals’ adaptive capacity is partially determined by learning and cognition, specifically one’s ability to process, assess and react to a changing climate. Formal education experience is thought to increase the learning and cognitive aspects of adaptive capacity. This study uses a novel method, Participatory Adaptation Scenario and Mapping Activity (PASMA) to explore the influence formal education may have on the decision-making processes of pastoral women as they adapt to drought in Samburu, Kenya. Our results indicate participants with formal education may be more risk-averse following drought, but initially assess and react to signs of drought similarly to peers without formal education experience. We argue that increased risk perception might be explained by formal education’s influence on the learning component of adaptive capacity. We also contend that formal education may fail to influence the agency of pastoral women as a result of systemic issues, and therefore limiting the potential of formal education to improve adaptive capacity.

In Science We Trust: The Effects of Information Sources on COVID-19 Risk Perceptions

ABSTRACT The goal of this study was to investigate the effects of sources of information on COVID-19 risk perceptions. Using data from a representative sample of the Portuguese population (N = 1,411) collected early in the pandemic, we find that while media sources were more frequently used, scientific sources played a more important role on perceived personal and societal-level risks; higher trust in scientific sources associated with increased risk perceptions (i.e., amplified perceived risk), trust in social media associated with dismissing personal threat (i.e., attenuated perceived risk). These findings suggest that people’s relations with science were determinant factors in risk perceptions, and dimensions that measure these deserve further investigation.

An intervention study of the rural elderly for improving exposure, risk perception and behavioral responses under high temperature

The frequency and intensity of high-temperature events continue to increase, resulting in a surge of pathogenicity and mortality. People with low levels of risk perception and adaptability, such as the elderly, suffer more from high temperatures. Effective intervention measures may lead to reduced levels of high temperature-related risk. The purpose of this study was to compare changes in temperature exposure, risk perception and coping behaviors under different intervention methods. Herein we conducted three different interventions including education, subsidies for electricity and uses of spray-cooling appliances as well as collected data about temperature exposure, risk perception, and coping behaviors. Before and after the experiment, we evaluated the intervention effectiveness with a number of variables related to alerting human responses under high temperatures. We conducted nonparametric tests for paired samples and generalized linear mixed effect models. Compared with subsidy support and outdoor spray-cooling methods, education is more effective as it leads to lower levels of temperature exposure, higher levels of risk perception, and more behavioral responses. The subsidy support intervention is useful in increasing risk perception and promoting home cooling practices as well. In comparison, spray cooling barely contributes to the reduction of personal temperature exposure. The encouragement of risk-related education and continued government subsidy may prevent elderly individuals from experiencing high-temperature exposure.

Fish Disease Outreach Messages: Testing of Gain and Loss Frames

Gain and loss framing has been used in risk communication across many fields as a technique for shaping individuals’ behaviors. Via community-engaged research conducted with the Michigan Department of Natural Resources, we tested five message frames to determine efficacy for outreach programs. We made the following determinations: (a) for increasing risk perceptions regarding fish disease, a loss frame in a fish disease management context should be used; (b) for decreasing risk perceptions regarding fish disease management, a gain frame in a fish disease context should be used; (c) for motivating behavioral intention regarding prevention and risk reduction, a gain frame in a fish disease context should be used. Our findings are of interest to Extension professionals and others working in natural resources.
