RESUMO
Per- and polyfluorinated substances (PFAS) contamination is an emerging environmental and health risk facing the world. This study examines the impact of conflicting information on Americans' attitude toward PFAS regulation and intention to engage in mitigation behaviors through a one-way, between-subjects experiment. Participants were 1,062 U.S. adults recruited from CloudResearch. Results showed that compared to participants exposed to consistent information, those exposed to conflicting information displayed less favorable attitude toward existing regulation, which led to lower intention to support related policies and to engage in mitigation behaviors. Political ideology moderated these relationships, with stronger experimental effects among conservatives. These findings underscore the importance of conveying consistent risk messages, especially when multiple stakeholders are involved.

Per- and polyfluoroalkyl substances (PFAS) contamination is an emerging environmental and public health crisis. Thus, it is crucial to understand public risk perception and communication behaviors surrounding this issue. Guided by the heuristic-systematic model of information processing, this study explores the impact of conflicting information and personal relevance on information insufficiency and information processing. Through an online experiment, 1,062 U.S. adults were randomly assigned to one of four conditions as part of a 2 (information type: conflicting vs. consistent) × 2 (personal relevance: high vs. low) between-subjects factorial design. Both main effect and interaction effect were detected. Specifically, information insufficiency was highest among participants in the high personal relevance and consistent information condition. Personal relevance also had a main effect on information processing. Conflicting information indirectly elevated information processing through increased information insufficiency, but only when personal relevance was low. These findings suggest the importance of providing consistent and personally relevant information related to the risk of PFAS contamination.
RESUMO
Based on survey data collected from a nationally representative sample (N = 1,000), this study applies the psychometric paradigm to demonstrate that the American public perceived the monkeypox outbreak as a more dreaded risk than the monkeypox vaccine, but they also viewed the monkeypox vaccine as a more unknown risk. These perceptions influenced their overall risk judgment toward the monkeypox outbreak, support for public health responses and government assistance measures, and likelihood to get vaccinated. Contributing to research on risk perception, these findings indicate that the dread and unknown dimensions offer a more intricate assessment of risk perception beyond perceived susceptibility and perceived severity. Guiding risk communication practice, these results suggest that it is important to highlight to the public that the monkeypox vaccine is a mature technology and getting vaccinated before exposure provides the best protection for high-risk populations.

The waste problem in the U.S. has only intensified in recent years, first due to China's National Sword Policy and then to the COVID-19 pandemic. One solution to this problem is to encourage people to adopt pro-environmental behaviors such as opting for reusables and products with plastic-free alternate packaging. In this study, we employ the value-belief-norm theory to examine whether its proposed causal chain predicts consumers' willingness to use reusables and products with plastic-free alternate packaging. We also explore the moderating role of perceived behavior control, one of the strongest predictors of environmental behaviors. Our research provides support to the value-belief-norm theory in predicting behavioral willingness. The moderating role of perceived behavior control provides additional insight into the theoretical model and furnishes practical implications for strategic communication designed to encourage the adoption of reusables and alternative packaging.

ABSTRACTGuided by the risk information seeking and processing model, this study examines social cognitive variables that motivate individuals to actively seek and process information related to per- and polyfluoroalkyl substances (PFAS) contamination. Results indicate that information insufficiency, affective response, and informational subjective norms are positively related to information seeking and systematic processing, which are positively associated with policy support and intention to adopt risk mitigation behaviors. These findings suggest that when communicating the health risks of PFAS contamination to the general public, cognitive, affective, and normative factors are important initial steps to generate public interest in relevant information.

Guided by construal level-theory, this research seeks to understand the effect of perceived psychological distance on emotions and risk perception associated with the COVID-19 pandemic in its early stage. Survey data were collected from a nationally representative U.S. adult sample (N = 1009) in April 2020. Results reveal that social distance was negatively related to emotions and risk perception. However, hypothetical distance was not significantly related to these variables. Emotions and risk perception also mediated the relationship between social distance and support for aid response measures; theoretically, we demonstrate that people evaluate risks contingent on their emotions when making decisions. This research contributes to extant literature on psychological distance and its utility in communication messaging design during public health crises.

Narratives have been identified as an effective tool to communicate seemingly abstract and uncertain risks. This study integrates the construal level theory of psychological distance and narrative persuasion to examine how distance-framed narratives influence young adults' attitude, behavioral intention, and policy support related to ocean plastic pollution. Results from an experimental survey (N = 889) indicate that the narrative featuring socially close characters and spatially close location is least effective in producing persuasive effects. Instead, the narrative depicting socially close characters' encounters at a spatially distant location is more persuasive. Within narrative conditions, the findings support the mediating role of identification and transportation in facilitating narrative effects. Serial mediation of identification/transportation and psychological distance perception was also observed. Findings from this study offer meaningful theoretical and practical implications for strategic communication on ocean plastic pollution.

This study, based on data collected from a representative sample of adults in the United States, explores the social cognitive variables that motivated Americans to validate rumours on social media about Hurricanes Harvey and Irma, both of which struck in August/September 2017. The results indicate that risk perception and negative emotions are positively related to systematic processing of relevant risk information, and that systematic processing is significantly related to rumour validation through search engines such as Google. In contrast, trust in information about the hurricane is significantly related to validation through official sources, such as FEMA (Federal Emergency Management Agency), and major news outlets such as The New York Times. Trust in information is also significantly related to systematic processing of risk information. The findings of this study suggest that ordinary citizens may be motivated to validate rumours on social media, which is an increasingly important issue in contemporary societies.

A national survey (N = 1025) conducted in August 2021 reveals that Americans' belief in misinformation about COVID-19 was negatively associated with vaccine acceptance. Importantly, the more participants believe in misinformation, the less anticipated regret they experience for not getting vaccinated. Reduced anticipated regret is associated with lower levels of vaccination intention and vaccine acceptance. To counteract the negative impact of misinformation, this study reveals the potential of an under-researched emotion in overcoming vaccine hesitancy.

Public participation in proper recycling is a crucial means to deal with the crisis in the U.S. recycling market. In this study, we combine the norm activation model (NAM; Schwartz 1977), the information-motivation-behavioral skills model (IMB; Fisher et al. 2003), and the theory of interpersonal behavior (TIB; Triandis 1977; 1979) to investigate recycling intention and behavior. Based on a longitudinal sample of New York state residents (N = 520), the results show that the integrated model fits the data well. Personal norm, habit, and recycling intention are three direct predictors of recycling behavior. Recycling intention is directly influenced by personal norm and behavioral skills, and indirectly influenced by personal motivation, social motivation, and ascription of responsibility. These findings suggest the importance of the normative approach in environmental campaigns to encourage recycling.

Recently, repeated childhood vaccine scandals shook public confidence in vaccine safety in China. This study explores whether media attention, online discussion, and social trust influence Chinese parents' risk perception and vaccination intention. Based on data from a Qualtrics panel (N = 354), results indicate that media attention is positively related to social trust and online discussion is positively related to perceived benefits. Additionally, social trust is negatively associated with perceived risk but positively associated with perceived benefits. Social trust is also positively related to general vaccination intention and intention to get domestic vaccines. Further, social trust mediates the relationship between media attention/online discussion and risk perception. Lastly, parents with higher risk perception are less likely to get domestic vaccines, but more likely to get imported vaccines. Perceived benefits also influence vaccination intention.

Psychological distance can influence a variety of risk-related perceptions and behaviors. This study (N = 205) examines the effect of spatial distance manipulation on emotions, risk perception, and behavioral intention following a recent measles outbreak in the United States. Results indicate that experimentally induced spatial distance influences emotional intensity, which affects psychological distance perception. Perceived distance subsequently influences risk perception, while emotions influence information engagement and support for mandatory vaccination.

Research has long identified narrative persuasion as an effective health communication strategy. This study explores temporal distance perception, which is the perceived distance of a health threat, as a possible psychological mechanism through which narrative persuasion influences young adults' attitude and behavioral intention related to e-cigarette use. When reading the narrative message featuring negative consequences of nicotine addiction, participants demonstrate a higher level of transportation and subsequently perceive the health threat related to e-cigarette as temporally closer. The shortened temporal distance perception, along with transportation, mediates the relationship between exposure to the narrative message and participants' attitude and behavioral intention. Participants' past experience also plays an important role. In particular, participants who have not used e-cigarette before report more negative attitude after reading the narrative message. Findings of the current study indicate that narrative persuasion may be an effective strategy to deter young adults from using e-cigarettes.

This study examines the interaction effect of message format (narrative vs. nonnarrative) and message framing (gain vs. loss) in e-cigarette prevention targeting young adults. Results of a two-way experiment (N = 439) revealed that transportation and discrete emotions mediated message effect on risk perception and behavioral intention. Compared to the gain-framed nonnarrative, the gain-framed narrative reduced feelings of guilt, and guilt was negatively related to risk perception and positively related to behavioral intention. Thus, the gain-framed narrative achieved desirable persuasive outcome through guilt-increasing risk perception and decreasing intention to use e-cigarette. Similarly, the loss-framed narrative evoked greater sadness, which also led to increased risk perception and decreased behavioral intention. Transportation and discrete emotions mediated message effect in a serial order. This research not only contributes to the literature on narrative persuasion and emotion, but also provides insight for health communication designed for e-cigarette prevention.

Construal-level theory suggests that high-level abstract features weigh more in people's decision-making at farther distance, while low-level concrete features weigh more at closer distance. Based on this, we propose that psychological distance will influence the effect of risk versus efficacy framing on climate change engagement. In particular, risk perception related to the end-state expectancy of climate change mitigation should influence people's climate change engagement at farther distance. In contrast, efficacy perception related to the perceived feasibility of attaining end-state goals should influence engagement at closer distance. Results from an experimental survey based on a national sample that is both demographically and geographically representative (N = 1,282) supported our proposition. At closer spatial distance, perceived efficacy boosted by efficacy framing increased participants' intention to perform climate mitigation behaviors. In contrast, at farther distance, risk framing increased behavioral intention through heightened risk perception. Based on these findings, we suggest that when communicating distant and abstract risks, highlighting their disastrous impacts may better motivate action. In contrast, when communicating impending and concrete risks, stressing the feasibility of action may have stronger motivational potential.

Analyses of disaster resilience have focused increasingly on the role of social capital and online social networks in recovery. This study complements this field of work by investigating three key issues. First, it examines how a social messaging application, WeChat, helped individuals to access and to mobilise three types of social capital-bonding, bridging, and linking-during Hurricane Harvey, a Category 4 storm that made landfall in Louisiana and Texas in the United States in August 2017, resulting in significant flooding and loss of life. Second, it pinpoints and assesses quantitatively how individuals' WeChat group usage and social capital influenced their post-disaster well-being. Third, it demonstrates how a minority and immigrant community in Houston, Texas, overcame the disadvantages commonly observed in other disaster research through the utilisation of social media. The findings of this study should aid governmental and community efforts to foster resilience in the face of natural and human-induced hazards.

To test a possible boundary condition for the risk information seeking and processing (RISP) model, this study experimentally manipulates risk perception related to the 2014 Ebola outbreak in a nationally representative sample. Multiple-group structural equation modeling results indicate that psychological distance was negatively related to systematic processing in the high-risk condition. In the low-risk condition, psychological distance was positively related to heuristic processing; negative attitude toward media coverage dampened people's need for information, which subsequently influenced information processing. Risk perception elicited more fear, which led to greater information insufficiency and more heuristic processing in the low-risk condition. In contrast, sadness was consistently related to information processing in both conditions. Model fit statistics also show that the RISP model provides a better fit to data when risk perception is elevated. Further, this study contributes to our understanding of the role of discrete emotions in motivating information processing.

Unlike the United States, where human papillomavirus (HPV) vaccines have been available for decades, China recently approved its first HPV vaccines. Setting up a baseline comparison between these two countries, this study examines the influence of message framing, motivational orientation, cultural worldview, knowledge, and gender on young adults' intentions to get vaccinated. Compared to the U.S. participants, Chinese participants perceived HPV as a more severe risk and were more willing to get the vaccine. However, they were also more skeptical about vaccine safety. Inconsistencies with previous research emerged regarding the moderating effects of motivational orientation and cultural worldview. Findings from this study offer important implications for HPV vaccine promotion in China.

Human papillomavirus (HPV) is a prevalent sexually transmitted infection (STI) among college students. Although previous research has studied HPV-related health communication strategies using various framing techniques, the goal of this study is to test how two unique message frames-whether mentioning HPV as an STI and whether to attribute the cause of infection as external or internal-would influence young adults' intentions to receive the recommended HPV vaccine. Results indicate that gender and causal attribution framing influenced participants' intentions to receive the HPV vaccine.

College students suffer disproportionately from human papillomavirus (HPV), a sexually transmitted infection (STI) that could result in genital warts or cancers in both males and females. Research contends that stigma and shame may serve as barriers to disclosure intentions, as well as vaccination intentions. The goal of this study was to examine whether two framing strategies-whether to mention that HPV is sexually transmitted and whether to highlight the cause of infection as internal or external-would influence young adults' intentions to disclose a potential diagnosis and their intentions to get the recommended HPV vaccine. Results indicate that STI framing and gender had consistent impacts on disclosure and vaccination intentions. Further, causal attribution framing also influenced participants' intention to get the vaccine at no cost immediately and their intention to get the vaccine at the retail price of $375 in the future. Theoretical and practical implications of these results are discussed.
