Focal points for improving communications about electromagnetic fields and health: a mental models approach

Central to the precautionary policy is the provision of information about electromagnetic fields (EMF) technology, exposures, potential health risks and exposure management actions to the public. To meet this need at the broadest level, beyond the specific technology foci of previous research, a research project was commissioned as part of Dutch Electromagnetic Fields and Health Research Programme. This study provides an assessment of Dutch EMF information needs from an ensemble of sources by addressing people’s existing ideas and beliefs, using a mental models approach. A summary expert model of influences on and consequences of exposure derived from search of the relevant literature is informed by interviews with 15 scientists and professionals with diverse expertise. Although the professionals characterize the physical characteristics and psychological aspects of exposure to EMF in daily life similarly, there is no consensus regarding potential health effects. Interviews with 12 lay people followed by a confirmatory survey of the general Dutch public (n = 403) reveal not only wide variation in beliefs regarding potential health effects of EMF, but also overestimation of the amount of radiation from public sources relative to personal sources of EMF. People do not feel adequately informed by the government about EMF, and knowledge of government policies on EMF is limited. Together, the evidence suggests three focal points for improving EMF risk communications: providing more clarity regarding the uncertainty of evidence for health effects, illuminating personal EMF exposures in daily life and providing more accessible and transparent information on governmental policies.     

Public perception of dementia risk in the UK: a mental models approach

Abstract

Dementia is a leading cause of death in the developed world. A number of modifiable risk factors for dementia have been identified, yet lay knowledge on dementia risk is limited. A mental models approach was used to compare lay and expert knowledge of risk in order to identify target areas for lay education. This method assumes experts and laypeople use different cognitive representations to make sense of phenomena. Semi-structured interviews were conducted with 8 experts and 15 laypeople to construct mental models of dementia risk. Interviews were transcribed verbatim and entered into NVivo qualitative data analysis software for coding. Findings indicated that laypeople had some knowledge of modifiable risk factors but in contrast to the expert mental model, laypeople poorly understood the causal links between these factors and dementia risk. Lay participants were unsure of the interaction between modifiable and non-modifiable risk factors and primarily attributed dementia risk to ‘bad luck’. It is suggested that future dementia education could benefit by building upon a general appreciation of healthy behaviour with particular focus on explaining the causal pathways to dementia risk. Additionally, it may be productive to inform laypeople it is possible to ‘change one’s luck’ by engaging in protective behaviours.     

Fear and anger: antecedents and consequences of emotional responses to mobile communication

Many people fear that exposure to mobile phone base stations leads to severe health effects. In addition to those fears, many citizens are unsatisfied or even angry about prevailing base station site-selection procedures. In the present study, it was investigated how these emotions, i.e. fear and anger, determine risk and benefit perceptions and the acceptance of mobile communication. Using structural equation modeling, we found that benefit perception and the acceptance of mobile phone base stations were primarily determined by anger. Risk perception, in contrast was influenced by both emotions. In addition, controllability and fairness emerged as important cognitive appraisals, or antecedents, of fear and anger, while certainty was not related to these emotions. In sum, our findings highlight that fear and anger have specific influences on risk, benefit, and acceptance of mobile communication. Furthermore, the study provides an in-depth understanding of the antecedents that lead to emotional responses within the context of mobile communication. Implications for risk communication will be derived.     

A comparative study of stakeholder risk perception and risk communication in Europe: a bovine spongiform encephalopathy case study

The ‘Transmissible Spongiform Encephalopathy (TSE) Roadmap’ was published by the European Commission on 15 July 2005. The TSE Roadmap proposes the relaxation of bovine spongiform encephalopathy (BSE) measures in the short, medium and long term. According to the Roadmap, any relaxation of BSE measures following the scientific assessment should be initiated by an open discussion with all stakeholders and supported by a strong communication strategy. This paper discusses the risk perception, risk communication and risk management of TSEs in Europe, exemplified by the TSE Roadmap. The main conclusion is that in general, BSE is no longer a ‘hot’ topic for stakeholders, but there are slight differences between countries with respect to specific measures. Another important conclusion is that the TSE Roadmap is a very effective tool for risk communication with stakeholders.     

Risk perception and risk management in Norwegian aquaculture

This exploratory study seeks to provide empirical knowledge about fish farmers' risk attitudes, risk sources and risk management tools by presenting the results from a survey among Norwegian fish farming companies. The results show that fish farmers think of themselves as only moderately risk averse compared, for instance, to crop and livestock farmers. The most important sources of risk are considered to be future salmon prices, institutional risks and fish diseases, while keeping costs low is the most important risk management tool.     

Risk communication in dementia care: family perspectives

Family carers are often involved in decisions concerning the health and social care needs of people with dementia. These decisions frequently involve considering risks inherent in daily living situations and discussing these with care recipients and professionals. The purpose of this study is to understand the risks that present most concern to family carers; explore attitudes and approaches of this group towards risk; and examine how information about risks is shared between familial carers, care recipients and professionals working in dementia care. Five focus groups were held across Northern Ireland between April and July 2015 involving 22 carers. Risks of most concern were driving, falls, financial risks, getting lost and using electrical appliances. Concepts of ‘risk’ related to terms such as danger, harm and vulnerability with emphasis on consequences rather than likelihoods. The psychosocial benefits of taking risk were recognised by some participants. Discussion of risks with family members with dementia primarily involved bringing risk matters to the attention of the individual. Family carers talked with a wide range of professionals about risks. Divergences in perspectives were noted, particularly in relation to matters of health and safety. A model of risk communication is developed illustrating how this can play a key role in informed, shared decision-making where a family member has dementia, serving an important role in risk management processes in informal community dementia care.     

Perception of technological risk: insights from research and lessons for risk communication and management

Technology has become a familiar companion in all areas of life. Production consumption, administration, education, communication, and leisure activities are all shaped by the use of technologies. However, people often associate with the term ‘technology’ attributes, such as catastrophic and potentially dangerous, and tend to take the benefits of technological products for granted. This asymmetry in risk–benefit perception is one of the main reasons why many consumers are concerned about ‘hidden’ risks of technologies and why they demand stringent regulatory actions when they feel unduly exposed to potential emissions or waste products associated with the lifecycle of technologies. This situation is often aggravated by social amplification processes, by which even small risks receive high media attention and are blown out of proportion in the public arena. At the same time, however, one needs to acknowledge that many technologies have the potential to harm the human health and the environment. The purpose of this article is to review our knowledge about risk perception with respect to technologies, in particular emerging technologies, and to suggest possible strategies to use this knowledge for improving our risk management practice. Technological risk perception is defined in this article as the processing of physical signals and/or information about a potentially harmful impact of using technology and the formation of a judgment about seriousness, likelihood, and acceptability of the respective technology. Based on the review of psychological, social, and cultural factors that shape individual and social risk perceptions, we have attempted to develop a structured framework that provides an integrative and systematic perspective on technological risk perception and that may assist risk management and regulation in taking perceptions into account.

Risk perception and risk management in the Middle East market: theory and practice of multinational enterprises in Saudi Arabia

This exploratory study investigates the risk perception and risk management strategies of Western multinational enterprises in the Middle East. A sample of 49 German companies operating in Saudi Arabia provides the empirical setting for this research. The study reveals that cultural risk is assessed as more important in the business environment than political, financial, and economic risk. The most critical risk factors are not sufficiently included in the methodology of country risk measures, which are often used as a source for country‐specific risk information. In terms of risk management strategies, participating firms use mostly informal approaches rather than structured hedging or insurance products. Furthermore, we find that firm size has implications on the perception of some risk factors and for the level of risk management sophistication.     

Risk communication for catastrophic events: results from focus groups

Focus group methods are adapted here to address two important needs for risk communication: (1) to provide approaches to risk communication in very extreme and catastrophic events, and (2) to obtain risk communication content within the specific catastrophe area of chemical and biological attacks. Focus groups were designed and conducted according to well‐established protocols using hypothetical sarin and smallpox attacks resulting in a chemical or biological release in a confined public space in a transit system. These cases were used to identify content for risk communication information and suggest directions for further research in this area. Common procedures for conducting focus groups were used based on an initial review of such procedures. Four focus groups – two for each type of release – each lasted about two hours. Participants were professionals normally involved in emergencies in health, emergency management, and transportation. They were selected using a snowball sampling technique. Examples of findings for approaches to communicating such risks included how information should be organized over time and how space, locations, and places should be defined for releases to anchor perceptions geographically. Examples of findings for risk communication content are based on how professionals reacted to risk communications used during the two hypothetical releases they were presented with and how they suggested using risk communications. These findings have considerable implications for using and structuring focus groups to derive risk communication procedures and types of content to be used in the context of catastrophes.     

Climate-induced migration: using mental models to explore aggregate and individual decision-making

The US Dust Bowl of the 1930s (a prolong period of drought experienced in the United States accompanied by severe sand storms) is often described as an abnormal event. However, climate change is likely to increase the frequency and impact of similar occurrences. Because of this, a growing number of scholars have begun to examine multiple facets of climate-induced migration from various disciplinary traditions. Specifically, scholars have called for continued research into individual decision-making processes. Responding to this call, we construct a mental model from historical interviews of those who migrated to California during the US Dust Bowl. Our model provides insight into the migration process with a unique focus on individual decision-making processes of migrants.     

Risk communication and the FSA: the food colourings case

Food colourings and flavourings have a long history. Spices and preservatives have been added to foods for millennia in order to make them last longer and taste better. Herbs, spices, pepper and salt, and other natural flavours and preservatives remain popular to this day. But over the last century or so the food and drinks industry has in many cases replaced or added to naturally occurring preservatives and colourings with synthetic compounds. All natural and artificial colours, flavours and preservatives that are added to food and drink have been tested and approved as safe by the regulatory authorities in the western world. However, campaigners in several nations, particularly the UK, have attempted to have some artificial colours and preservatives banned on public safety grounds, ranging from alleged skin allergies and asthma to hyperactive children. None of these allegations has been substantiated for any individual substance by the regulatory authorities. This paper evaluates how the UK Food Standards Agency (FSA) communicated the scientific findings of the so‐called Southampton study, which claimed to demonstrate a link between the consumption of a mixture of six artificial colours and one preservative and hyperactivity in children, and was published in September 2007 in the medical journal, The Lancet. The study is based on a content analysis of UK‐based newspapers from March 2007 to July 2008, as well as interviews with staff at the UK FSA, the European Food Safety Authority (EFSA), industry representatives, academics (including Professor Jim Stevenson who was the supervisor of the food colourings study at Southampton University) and campaign groups.     

Risk cultures and dominant approaches towards disasters in seven European countries

This paper builds upon the risk culture concept started with Mary Douglas’ and Aaron Wildavsky’s seminal work on risk and culture. Based upon the empirical results of a qualitative sociological study on sociocultural factors affecting risk perception and crisis communication in seven European countries, a theoretical model, illustrating how differences in disasters framing imply diverse approaches to risk and disaster management, is suggested. According to this framework, culturally bounded assumptions and conventions strongly influence how communities make sense of risks and hazards and how these communities consider some ways of dealing with disasters more appropriate than others. The framework suggested in this article distinguishes between risk cultures of a given society, which do not necessarily respond to nation states. In order to explain differences in how cultures deal with risks and disasters, and to define the main features of our typology, three main interrelated dimensions have been selected: disaster framing, trust in authorities and blaming. By analyzing differences and similarities in how people perceive and interpret disasters, as well as to whom the responsibility for risk prevention and crisis management is attributed, in seven European countries, three specific ideal types of risk cultures emerged: state-oriented risk culture, individual-oriented risk culture and fatalistic risk culture. Implications for crisis management and communication in case of a disaster will be addressed for each of these risk cultures.     

Risk and crisis communication narratives in response to rapidly emerging diseases

The uncertainty inherent in crises can create a narrative space that is often filled by multiple interpretations about both what is happening and what steps should be taken to resolve the crisis. As more information becomes known, these competing crisis narratives gradually merge into a dominant narrative about the crisis, lessons learned from it, and recommendations for the future. This case study examines the swine industry’s response to the Porcine Epidemic Diarrhea virus (PEDv) outbreak. The virus spread rapidly throughout the industry and, in a matter of months, had killed approximately 10% of the U.S. swine population. This analysis examines the crisis communication that ensued during that time. More specifically, 13 specialists representing the National Pork Board, American Association of Swine Veterinarians, veterinarians highly active in treating PEDv, university extension agents, and academic researchers were interviewed for this study. A narrative analysis of the interview content revealed that communication efforts made by swine industry leaders successfully shifted the PEDv story from that of competing narratives to a dominant narrative that helped resolve the crisis efficiently. This success is attributed, in part, to effective use of all available industry resources for both conducting research and sharing information rapidly through pre-established communication networks and widely read resources. Results of this narrative analysis reveal a key recommendation that maybe generalizable to similar crisis events. That is, an effective crisis narrative should focus not only on what protective actions to take, but also on a clear explanation regarding the nature of the crisis. Moreover, such explanations must be translated intelligibly to diverse non-scientific publics and provide a compelling rationale for why the recommended actions are vital.     

Risk communication and citizen engagement: what to expect from dialogue

Despite the last few decades’ devotion to deliberative methods in risk communication, many studies point to how important challenges arise when citizens are engaged in public dialogue. Since the era of enlightenment public dialogue has occupied a position as a normative ideal for political governance. But ideals are social constructions that have a tendency to direct attention away from underlying conflicts. The concept of dialogue is no exception, and exemplified by the Danish solution to dealing with public scepticism in relation to technological controversies, the internationally acclaimed ‘consensus conference’, the paper seeks to offer a better understanding of the contemporary use of the concept of dialogue as well as its ancient roots. The paper argues that behind the aspirations for deliberation lie two opposing models of dialogue. When these two models encounter in deliberative processes, their different presumptions about the role of communication symmetry are likely to appear. This points to how the models hold very different expectations as to the dialogical outcome, thus imposing some fundamental conflicts regarding the political efficacy of citizen engagement as a strategy for bridging the gap between expert and lay attitudes to societal risks.     

The stability of risk and benefit perceptions: a longitudinal study assessing the perception of biotechnology

The study of public perceptions is considered to be important for making sound policy decisions, since the public decides which products will enter and sustain in the market. Stability of public perceptions is important for policy-makers; only if public attitudes and perceptions remain constant, policy-makers will be able to take them into account. The aim of the present study was to examine the stability of participants’ risk and benefit perceptions of gene technology over a period of two years. In spring, 2008 and in spring, 2010, the same sample of participants filled out an identical questionnaire. Results of structural equation modelling show that risk and benefit perceptions of gene technology applications are moderately stable (r = .5–.7). Furthermore, results show that people distinguish between medical, plant and food applications and applications involving animals when evaluating the risk of gene technology. When evaluating the benefits, participants also take consumer-related benefits into account, such as enhancement of functional properties. Results of the present study suggest that risk research should regularly examine people’s risk perceptions in order to gain a clearer picture of the dynamics of people’s perception and preferences not only of novel technologies, but also of entrenched technologies.     

Precautionary advice about mobile phones: public understandings and intended responses

There is a widespread academic and policy debate about public responses to precaution in public health campaigns. This paper explores these issues in relation to the precautionary stance adopted in the UK around the regulation of mobile telecommunications. The aim of the paper is to examine the nature of attitudes to precaution, and the way in which these, along with other relevant variables, relate to the intention to adopt relevant behaviours. The results from an experimental study (n = 173) indicate that people distinguish between two dimensions of precaution: firstly in relation to its value or necessity per se and secondly as anchored to notions of governance. The two variables differentially relate to other variables including trust and uncertainty, and are predictive of intended behaviour change indirectly, through worry about mobile phone risks. Precautionary advice was generally interpreted as causing concern rather than providing reassurance. The results suggest that precaution may be considered a valuable stance but this does not mean that it is seen as good governance or that it will reduce concern. Whilst the discourse of precaution is aimed at reducing concern, it appears that the uptake of relevant behaviours is largely triggered by worry.     

Risk communication policy design: Cyprus compared to France and the Netherlands

This study aims at analyzing differences between risk communication policies in Cyprus, compared to the Netherlands, and France. It analyzes risk communication policies indirectly through a qualitative analysis of the information provided by official websites, which are considered to be proxies of these policies. The websites review will focus on the type of the information disclosed online, and the similarities and differences between the websites, regarding the information provided, the way it is communicated, the backing on credible sources, and the supplying of more information if desired, but also simply through the presenting of the WebPages. The results indicate that the Netherlands and France have created risk dedicated websites besides the ministries’ websites with information on risks, prevention and the authorities’ actions. There is a gap between strategies. The Dutch strategy is to give more responsibilities to the public, by encouraging individuals to be resilient and responsible for their own safety at a certain level by promoting preventive behaviors. The French strategy is to provide risk-dedicated information to the public, also on prevention and government actions. Opposed to this, the Cypriot authorities simply avoid this strategic question by confining the risk communication to the crisis phase, without entrusting people with a role in risk management, and by strictly one-directional communication, with government delivering and the public digesting (or not). Suggestions for risk communication policy development are discussed.     

Helping behavior in a virtual crisis situation: effects of safety awareness and crisis communication

Incident evaluations show that bystanders tend to help: they do not wait for professionals to arrive, but act as required by the situation at hand. In the present study, we investigated how safety awareness (induced before an accident happened) and providing a course of action by emergency services affect helping behavior after witnessing a virtual accident with two victims. The main task of the participants was to arrive at a job interview in time. Safety awareness was manipulated by the specific organization they went to: either promoting safe traffic or healthy living. The results show that all participants were inclined to help. Participants who were primed towards safe traffic more often called the emergency number, but talked to the victim less often. Participants who had received specific courses of action moved the victim less often. In all, the results clearly indicate the value of effective risk communication (before an event occurs) and crisis communication (after an event has occurred), as both types of information improve the quality of actual helping behavior at the scene.
