At the onset of the COVID-19 pandemic, social distancing measures and diffuse communication by media led to consumers’ uncontrolled product purchases worldwide. This phenomenon was described as a psychological effect experienced by fictitious scarcity, anxiety and herd mentality exacerbated by the media. This exploratory study aims to analyze the impact of risk communication on the perceived risk from the psychological dimension of consumer behavior amid the COVID-19 pandemic.

An exploratory study was conducted through an electronic survey one week after implementing social distancing measures in Puerto Rico. With a sample of 353 participants, the data analysis was carried out by PLS-SEM, partial least squares structural equations (PLS-MGA), multi group test (MGA) and hierarchical component models to answer the research hypotheses.

The results revealed that risk communication activates the perceived psychological risk during the COVID-19 pandemic, and the way in which the consumer faces the psychological risk is explained by the perceptions of scarcity and the bandwagon effect.

To the best of the authors’ knowledge, this study is a pioneer in presenting relationships between risk communication and perceived risk in consumer behavior, a topic that needs to be addressed in the academic literature. The research makes significant contributions to the study of consumer behavior by empirically validating the three phases of the Conchar model – risk framing, risk assessment and risk evaluation – where risk communication offers an excellent delineation to understand the consumer’s behavior during a pandemic.

This study provides real-world evidence for the relationship between strategic communication from a global/multinational perspective and the effectiveness of corporate message strategies in the context of environment risk communication. Among sustainability issues, particulate matter (PM) air pollution has threatened the health and social wellbeing of citizens in many countries. The purpose of this paper is to apply the message framing and attribution theories in the context of sustainability communication to determine the effects of risk message characteristics on publics’ risk responses.

Using a 2 (message frame: gain vs loss) × 2 (attribution type: internal vs external) × 2 (country: China vs South Korea) between-subjects experimental design, the study examines the message framing strategies' on publics' risk responses (i.e. risk perception, risk responsibility attribution held toward another country and sustainable behavioral intention for risk prevention).

Findings include (1) main effects of message characteristics on participants’ risk responses; (2) the impact of country difference on participants’ differential risk responses and (3) three-way interactions on how risk message framing, risk threats type and country difference jointly affect not only participants’ risk perception and risk responsibility attribution but also their sustainable behavioral intention to prevent PM.

Although this study used young–adult samples in China and South Korea, the study advances the theory building in strategic environmental risk communication by emphasizing a global/multinational perspective in investigating differences among at-risk publics threatened by large-scale environmental risks.

The study's findings provide evidence-based implications such as how government agencies can enhance the environmental risk message strategy so that it induces more desired risk communication outcomes among at-risk publics. Insights from our study offer practical recommendations on which message feature is relatively more impactful in increasing intention for prosocial behavioral changes.

This study on all measured risk responses reveals important differences between at-risk young publics in China and South Korea and how they respond differently to a shared environmental risk such as PM. The study's findings provide new evidence that media coverage of global environmental issues needs to be studied at the national level, and cross-cultural comparisons are imperative to understand publics’ responses to different news strategies. Thus, this study offers implications for practitioners to understand and apply appropriate strategies to publics in a social way across different countries so as to tailor risk communication messaging.

This study offers new insights to help connect message framing effects with communication management practice at the multi-national level, providing recommendations for government communication practitioners regarding which PM message features are more likely to be effective in forming proper risk perception and motivate sustainable actions among at-risk publics in different countries.

The intent of the work is to go beyond the conventional model of disaster risk prevention, where community residents are objects of risk communication initiatives, and develop and implement a relational model of risk communication wherein they are active agents of knowledge transfer.

The relational model of risk communication translates risk knowledge into narrative forms that community members can share. The article discusses the conceptual basis of the model and, then, describes how it has been pilot tested and implemented in the field. Evaluation of the pilot tests consist of pre- and post-surveys comparing control and test groups.

Encouraging results have been seen among vulnerable communities, such as residents in a refugee camp and schoolchildren in a storm surge vulnerable town. These outcomes support the idea that the relational approach can empower residents to be active agents of risk communication.

The relational model taps into the knowledge and agency of community.

The purpose of this case study was to analyze risk communication management practice of Brookhaven National Laboratory (BNL), using the relationship management theory in public relations.

The study draws upon interviews with key stakeholders of the laboratory, including top managers, communication practitioners, employees, and community members. Media reports, internal documents, and on‐site participant observations were concurrently analyzed.

The study identified leadership communication, organizational commitment to stakeholder relationships, integrated communication function, employee participation in community outreach, and symmetrical communication strategies as contributing factors of effective risk communication management. In particular, the study provided insights into the roles employees play in risk communication settings. It was found that employees' use of symmetrical communication strategies such as openness, access, and listening in risk communication programs contributed to external publics' development of positive perceptions regarding the organization.

The article concludes with four implications of the findings for the practice of risk communication.

This study closely followed the methods by which public relations practitioners, non‐public relations employees, and publics engaged in the relationship building process. The case study should, therefore, provide insights to students and scholars interested in discovering public relations theory at work in a real‐life setting.

The purpose of this rapid scoping review was to map existing literature on risk communication strategies implemented by authorities and aimed at vulnerable immigrants in the context of pandemics.

Existing literature on the topic was charted in terms of its nature and volume by summarizing evidence regarding the communication strategies. Literature searches were conducted in Academic Search Premier and CINAHL, databases were searched from 2011 to present on March 31, 2021.

Five articles met the criteria and were included in this review, pointing at limited research in this area. The findings indicated that a close interaction between communication authorities and immigrants is important. Community education, building trust in communication sources, clear risk communication and inclusive decision-making among all were found to be important when communicating health risks to immigrants.

The primary limitation of this rapid scoping review is that the literature searches were conducted in only two databases, namely, Academic Search Premier and CINAHL. A wider search across several other databases could have given more profound results. Furthermore, some studies where immigrants were conceptualized as, for instance, “disadvantaged groups” might be overseen due to a choice of the search strategy used in this study. There are also certain limitations related to the studies included in this review.

Identifying efficient ways of conveying recommendations may further assist authorities and scientists in developing more effective health-related risk communication.

This study covered health-related risk communication in the context of pandemics, addressing the need to investigate different groups of immigrants and the challenges related to communicating risks to these groups.

COVID-19 presents a serious and unprecedented challenge around the globe. Street vendors are the most vulnerable group during this pandemic regarding livelihood loss and contagion risk. This research aims to examine the roles of risk communication work in enhancing COVID-19 risk perceptions and adoption of COVID-19 preventive behaviors among street vendors.

The data were collected from the street vendors in urban Vietnam. A binary probit model was used for analyzing the relationships among exposure to risk communication, risk perception and adoption of preventive behaviors.

The analysis reveals the outreach of risk communication work to the street vendors. A rather large proportion of the respondents perceive high risks associated with COVID-19. All respondents adopt COVID-19 preventive behaviors; however, the proportion of regular adoption is moderate and even very low for most behaviors. Their frequent exposure to risk communication significantly raises their risk perceptions and encourages their regular adoption of preventive behaviors, particularly regarding the measures that are affordable and less detrimental to their livelihood.

This research is among the first attempts to examine risk communication to the vulnerable group, how they perceive risks and the extent to which they adopt preventive behaviors during a public health crisis. This research draws some implications for risk communication and social welfare policies to obtain sustainable development goals.

The aim of the study is to deepen the knowledge about municipalities' risk communication for preparedness. This objective was pursued by analyzing how risk communication functions were organized in municipalities and by scrutinizing tensions in risk communication management.

The study relies on 19 qualitative, semi-structured interviews with communication practitioners in Swedish municipalities. The sample was purposive and included Swedish municipalities varying in number of inhabitants, geographical location, degree of urbanization, size and risk profile.

Risk communication is seen as a sub-field of crisis communication in municipalities' communication management. The task of initiating risk communication activities and campaigns is frequently assigned to the municipalities' safety units or emergency coordinators and is normally not part of communication practitioners' duties. Municipal communication practitioners often face challenges in trying to demonstrate the significance of the practitioners' role in risk communication and other risk-related activities within the municipality. The practitioners' work is characterized by four categories of tensions that are identified as follows: constitutional/legal, organizational, cultural and technological.

The identified tensions in risk communication are important for reflexive practitioners to consider, and the paper suggests three steps that municipal communication managers can take to handle them.

The study contributes with novel knowledge about municipal communication management in a context of risk communication. The study challenges the existing and dominant risk communication research and offers a more contextual and reflexive understanding of actual risk communication processes in municipalities.

The purpose of this paper is to investigate risk dimensions affecting food risk perceptions and to develop effective risk communication strategies based on their risk perceptions dimensions. The reason for writing this paper is that applying single risk communication strategy for public often fails because food risks are systemic risks and public perceptions toward them consist of multiple dimensions. Launching an effective risk communication need to investigate the perception dimensions of the target audience.

A total of 2,673 parents of 3-14-year-old children from the rural area of Sichuan province in China were chosen as target audience. Based on the survey conducted about parents’ food risk perceptions, this study used factor-cluster analysis method to segment parents to sub-clusters with significantly different risk perception dimensions. Parents’ representative demographic characteristics within each cluster were further identified through cross-tabs analysis with χ² tests.

All the parents could be segmented into four sub-clusters, namely, sensitive parents, dependent parents, familiarity-oriented parents and institutional distrust parents, according to their risk perception difference on five dimensions. A series of risk communication strategies were specifically designed for each cluster based on their risk perception features as well as demographic characteristics.

The insight derived from this study described a deeper image of public risk perceptions and provided suggestions for risk communication launchers to pinpoint the risk perception as well as perception dimensions of the target audience and accordingly develop effective risk communication strategies.

The paper aims to contribute to the development of a systematic framework of analysis pertaining to the relationship between public health crisis (PHC) and scares and corporate communication practice. It aims to clarify the complex relationship between public health policy development and corporate crisis and risk communication issues.

Literature review in the fields of crisis communication, crisis and risk management and public health policy; the multidisciplinary approach provided principles for a framework of analysis.

The framework proposed identifies fields of intersection between governments, corporations, the media and the experts in the context of risk perception management providing inputs for both public health policy and corporate communication new developments.

The need for further research arises from the identification of the different areas of intersection between governments, corporations, the media and the experts and further elucidation of its dynamics should be pursued.

The framework builds a bridge between disciplines that have not been articulated for the practice inherent in public health and scares‐related communication issues. It proposes a multidisciplinary framework of analysis applicable to any type of PHC or scare.
