\n Purpose\n. A new strain of H1N1 influenza, also known as swine flu was confirmed in the UK in May 2009 and has spread to over 100 countries around the world causing the World Health Organization to declare a global flu pandemic. The primary objectives of this review are to identify the key demographic and attitudinal determinants of three types of protective behaviour during a pandemic: preventive, avoidant, and management of illness behaviours, in order to describe conceptual frameworks in which to better understand these behaviours and to inform future communications and interventions in the current outbreak of swine flu and subsequent influenza pandemics.\n

This article examines how health news gets framed and the influence of exposure to news framed differently. A content analysis of Taiwanese newspapers indicates that health news in general, and H1N1 flu news in particular, is more likely to use alarm rather than coping frames. According to an experiment, exposure to H1N1 flu news in an alarm frame evokes greater fear and increases perceived severity and vulnerability, though it does not help develop prevention and treatment efficacy. A survey of the general public also shows that attention and exposure to televised news coverage of the H1N1 flu are associated with greater levels of worry and perceptions of the severity of and vulnerability to this health problem, but they are not related to issue knowledge, detection, or prevention efficacy. Thus, it is important for news coverage to provide information that increases the audience's efficacy when alerting it to health threats.

This paper answers the question, “Why do organizations process information?” Uncertainty and equivocality are defined as two forces that influence information processing in organizations. Organization structure and internal systems determine both the amount and richness of information provided to managers. Models are proposed that show how organizations can be designed to meet the information needs of technology, interdepartmental relations, and the environment. One implication for managers is that a major problem is lack of clarity, not lack of data. The models indicate how organizations can be designed to provide information mechanisms to both reduce uncertainty and resolve equivocality.

The statistical tests used in the analysis of structural equation models with unobservable variables and measurement error are examined. A drawback of the commonly applied chi square test, in addition to the known problems related to sample size and power, is that it may indicate an increasing correspondence between the hypothesized model and the observed data as both the measurement properties and the relationship between constructs decline. Further, and contrary to common assertion, the risk of making a Type II error can be substantial even when the sample size is large. Moreover, the present testing methods are unable to assess a model's explanatory power. To overcome these problems, the authors develop and apply a testing system based on measures of shared variance within the structural model, measurement model, and overall model.

This study uses the psychometric paradigm (Renn & Rohrmann, 2000; Slovic, 1992) as an analytic framework to analyze the risk dimensions being conveyed in media coverage of Avian flu in Hong Kong and in the United States between 2003 and 2007. A quantitative content analysis of The New York Times and South China Morning Post stories showed different patterns of avian flu related risk content coverage. The differences revealed that dimensions related to dreadfulness, catastrophic potential, uncertainty, and unfamiliarity were more emphasized in The New York Times than in South China Morning Post. The authors discuss the implications.Copyright © Taylor & Francis Group, LLC

Although people nowadays engage in information communication repetitively through multiple channels during a public health crisis, the impacts of this communication on behavioral outcomes have not been fully examined. The present study empirically tests the effects of repetitive information communication through multiple channels (RICMC) on risk-prevention behavior. Additionally, the mediating roles of knowledge, perceived susceptibility, severity, response efficacy, and self-efficacy in the association between RICMC and risk-prevention behavior are examined. Analyses of online survey data (N = 1,036) collected during the 2015 Middle East respiratory syndrome (MERS) outbreak in South Korea revealed that RICMC was positively associated with MERS-prevention behavior. Furthermore, this association was mediated by perceived susceptibility, severity, and self-efficacy. Although response efficacy and knowledge were not significant mediators, RICMC was positively associated with all mediating variables. The implications, theoretical contributions, and limitations of this study are discussed.

Virtually all current theories of choice under risk or uncertainty are cognitive and consequentialist. They assume that people assess the desirability and likelihood of possible outcomes of choice alternatives and integrate this information through some type of expectation-based calculus to arrive at a decision. The authors propose an alternative theoretical perspective, the risk-as-feelings hypothesis, that highlights the role of affect experienced at the moment of decision making. Drawing on research from clinical, physiological, and other subfields of psychology, they show that emotional reactions to risky situations often diverge from cognitive assessments of those risks. When such divergence occurs, emotional reactions often drive behavior. The risk-as-feelings hypothesis is shown to explain a wide range of phenomena that have resisted interpretation in cognitive-consequentialist terms.

In 2015, South Korea experienced the largest outbreak to date of the Middle East Respiratory Syndrome (MERS-CoV) outside the Middle East. Fears related to a potential spread of the disease led to an increased alert level as well as heightened media coverage in the neighboring Hong Kong. A cross-sectional survey (N = 533) among residents of Hong Kong was conducted to assess the relationships between the effects of outbreak-related mass media coverage, interpersonal communication, the perceived level of concern in one's close environment, and the uptake of preventive measures. A serial multiple mediator model finds that interpersonal communication and higher perceived concern indirectly influence the effects of media coverage on the engagement in preventive actions. These results expand previous research on the mediating role of interpersonal communication and support assumptions about a modified two-step flow of communication in the context of a public health emergency.

This study looks at Pengpai (The Paper), the first news app launched in China by a traditional media organization, in order to understand how media practices in the context of contemporary China have shifted. The case of Pengpai, which was released in July 2014, is not only about economical and technological modernization but also relates to the re-negotiation of the relationship between the state, professionals and the public. Drawing on interviews with journalists, content analysis, a newsroom observation and Pengpai’s coverage of certain events, this research sheds light on the covert power interplay at work in newspaper digitization in China. The ambivalent accomplishment of Pengpai reveals the relationship between the state and journalists as a negotiation process that includes dialogue and conflict.

Studies of risk perception examine the judgements people make when they are asked to characterize and evaluate hazardous activities and technologies. This research 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 lay people, technical experts, and decision-makers. This work assumes that those who promote and regulate health and safety need to understand how people think about and respond to risk. Without such understanding, well-intended policies may be ineffective.

Despite the importance of social network sites (SNSs) in addressing emerging public health risks, there is still a relative lack of studies examining the effects of risk communication via SNSs on risk perceptions and preventive behaviors. Based on message expression‒ and reception‒effects paradigms, this study aims to explore how expressing and receiving risk information shape preventive behavioral intentions via risk perceptions. Given the differential nature and functionality of SNSs, the present investigation also examines whether expressing and receiving risk information via two different types of SNSs-Facebook and Twitter-have different effects on risk perceptions and behavioral intentions. Analyzing survey data from 1,152 South Korean adults in the context of fine dust hazards, this study found that expressing and receiving risk information not only affected risk perceptions but also directly or indirectly influenced preventive behavioral intentions. In addition, the effects of expressing and receiving risk information were differentiated between SNS platforms, specifically Facebook and Twitter.

Individuals use social network sites (SNSs) as an effective tool for communicating relevant information with others during the outbreak of infectious diseases. However, little is known about the underlying mechanism through which communicative behaviors influence preventive behaviors. Thus, in the context of Middle East respiratory syndrome (MERS) in South Korea, this study investigated how two communicative behaviors (message expression and reception) in SNSs affected the communicators' intentions to engage in MERS-preventive behaviors. Using data collected from a nationally representative panel survey of 1000 Korean adults aged 19 or older, we examined a theoretical expression and reception effects model. Results support the presence of effects from expressing and receiving MERS-related information via SNSs and their underlying mechanism during South Korea's MERS outbreak. Public health officials and communication professionals should actively use SNS communication in coping with public health crisis caused by emerging infectious diseases. (c) 2016 Elsevier Ltd.

Social media have become increasingly important in risk and crisis situations. However, little is known about which types of social media have greater influence on risk perceptions and behaviors. This study pursues two goals related to this question. The first is to explicate the cognitive mechanism underlying the process through which exposure to risk information on social media shapes people's behavioral intentions. The second is to determine whether exposures to risk information on two different types of social media-content-oriented social media focusing on shared interests versus user-oriented social media focusing on social relationships-have different effects on people's risk perceptions and behavioral intentions. Analyzing survey data from 688 adults from the general population of South Korea in the context of carcinogenic hazards, we found that self-reported content-oriented social media exposure (to risk information) was significantly related to both personal-level and societal-level risk perceptions. In addition, content-oriented social media exposure was associated with behavioral intentions indirectly through risk perceptions. However, user-oriented social media exposure had no impact on risk perceptions and behavioral intentions, either directly or indirectly through risk perceptions.

We conducted a content analysis of newspaper editorials on the Middle East respiratory syndrome outbreak in Korea. Subject matter, social and personal efficacy information, and affective tone were evaluated using a mixed-methods approach. An analysis of 241 publications with the acronym “MERS” revealed that public health was the most salient, followed by leadership/governance, coping, medical system, and economic consequences. Societal efficacy information was more frequent than personal efficacy information, and a negative tone was predominant. However, leadership became the most frequent in the later stages. Personal efficacy information decreased over time and across content with a negative tone.
