Full-text available
Antimicrobial-resistant (AMR) bacteria spread via food to humans and can seriously impair infection treatment. Hygienic food handling is an effective measure to avoid the transmission of bacteria. Therefore, we tested three types of interventions (tailored, generic, and no intervention) for their effectiveness in improving consumers' hygienic food...
Article
Full-text available
The feeding of waste milk containing antibiotic residues (WMA) to calves has been associated with the shedding of antibiotic-resistant bacteria by calves. However, little is known regarding farmers' intrinsic factors affecting this practice, and on which it would be relevant to intervene in order to change this practice. The objectives of this stud...
Article
Full-text available
People should use antibiotics (AB) prudently to mitigate antibiotic resistance (ABR). Previous studies—and, subsequently, interventions—on ABR have focused mainly on improving public awareness and knowledge. We investigated a comprehensive theory-based explanatory model to understand the public's decision making regarding prudent AB use, based on,...
Article
Full-text available
Animal owners' potential to observe and report clinical signs, as the persons with the closest contact to their animals, is an often neglected source of information in surveillance. Allowing community members other than health care professionals, such as animal owners, to report health events can contribute to close current surveillance gaps and en...
Article
Full-text available
Objectives We aimed to identify the potential of behaviour change strategies to effectively increase consumers’ risk awareness, behavioural intention, and preventive food-handling behaviour to reduce the transmission risk of antimicrobial-resistant bacteria through food. The applied strategies targeted knowledge and determinants of the health actio...
Article
Full-text available
Antimicrobial resistance (AMR) is an emerging global health concern, affecting both the animal and the human population. Transmission pathways of AMR are therefore abundant and complex, and ways to prevent or reduce transmission to consumers must be identified. The overall goal of this study was to define the content of an intervention study aimed...
Article
Full-text available
In this study, we aimed to explore the psychosocial factors related to consumers’ safe food-handling behaviors to reduce the transmission risk of antimicrobial-resistant bacteria through food products. To this end, we investigated the extent to which the variables of the health action process approach (HAPA) and subjective norms can predict safe fo...
Article
Two interventions were systematically evaluated in two university canteens on their effectiveness to reduce visitors' plate waste. The evaluation was theory-based and focused not only at the effects on the amount of plate waste, but also at the psychological predictors underlying plate waste behaviour. In Intervention A, visitors received informati...
Article
The energy transition in Switzerland, as in many other countries, aims to increase the proportion of electricity produced using renewable energy technologies. In this context, governmental agencies and other institutions have attempted to communicate the implications of (domestic) electricity systems through the use of web-based and interactive dec...
Chapter
How people think about a hazard often deviates from experts’ assessment of its probability and severity. The aim of this chapter is to clarify how people perceive risks. We thereby focus on two important research lines: (1) research on the psychometric paradigm, which explains variations between the perceptions of different risks, and (2) research...
Article
Food production and consumption account for approximately one-third of households' environmental impact. Consumers thus play a major role in the shift towards more sustainable foods and diets. An overall sustainability label or simple guidelines may enable consumers to make more environmentally friendly food choices, but whether such information-ba...
Article
Antimicrobial use in pig farming is influenced by a range of risk factors, including herd characteristics, biosecurity level, farm performance, occurrence of clinical signs and vaccination scheme, as well as farmers’ attitudes and habits towards antimicrobial use. So far, the effect of these risk factors has been explored separately. Using an innov...
Article
Full-text available
Chick culling is an efficient and cost-effective method in modern poultry farming, but it raises ethical concerns. Dual-purpose poultry (DP), in which males are fattened and females are used for egg production, is currently the most realistic alternative to culling, as in ovo sexing is not yet viable for practical application. Consumers’ acceptance...
Article
Climate change is a complex, multifaceted problem involving various interacting systems and actors. Therefore, the intensities, locations, and timeframes of the consequences of climate change are hard to predict and cause uncertainties. Relatively little is known about how the public perceives this scientific uncertainty and how this relates to the...
Article
Full-text available
Solar radiation management (SRM) aims to counteract the negative consequences of global warming and is considered for deployment in the event that mitigation and adaptation efforts appear insufficient. However, because the potential ecological and political side effects of SRM are not well understood, and because SRM will cross national boundaries,...
Article
Sustainability is becoming increasingly important in consumers’ food choices. Although consumers are known to rely on certain strategies for choosing sustainable food, such as preferring local and organic products, the extent to which these strategies affect the sustainability assessment of foods remains unknown. In an online experiment with 305 re...
Article
People often have to make decisions about problems that not only involve a probability of a risk, but also an uncertainty around this probability. In this paper, uncertainty that arises through a lack of knowledge (i.e. ambiguity) is distinguished from uncertainty that results from conflicting knowledge on the hazard's probability of occurring. Pre...
Article
In contemporary society, sustainable food production and consumption are increasingly important to mitigate climate change. Food production and consumption result in large greenhouse gas (GHG) emissions and thus have a large environmental impact. To positively influence consumers in reducing their food related climate impact, it is important to und...
Article
The prudent use of antimicrobials (AMs) should be widened in pig farming to reduce the risk of AM resistance (AMR) in human and veterinary medicine. It is therefore important to understand pig farmers' motivators and the barriers to AM usage (AMU) on their farms. The authors investigated pig farmers' self-estimated levels of AMU, their perceived be...
Article
Food production and consumption have major impacts on the environment. At the same time, changes in human diets worldwide are increasingly leading to health problems. Both issues are highly influenced by consumers' everyday food choices and could be addressed by reducing consumption of meat and other animal products. To promote sustainable food con...
Article
It is intuitive to assume that concern about climate change should be preceded by knowledge about its effects. However, recent research suggests that knowledge about climate change has only a limited effect on shaping concern about climate change. Our view is that this counterintuitive finding is a function of how knowledge is typically measured in...
Article
Full-text available
Antimicrobial (AM) resistance is an increasing problem in human and veterinary medicine. To manage this problem, the usage of AM should be reduced in pig farming, as well as in other areas. It is important to investigate the factors that influence both pig farmers' and veterinarians' intentions to reduce AM usage, which is a prerequisite for develo...
Article
It is important to understand better how people evaluate the environmental impacts of different food aspects. A longitudinal panel study design (. N=. 2600) was used to examine whether the perceptions of various environment-related, food consumption patterns changed between 2010 and 2014 and what factors influenced such changes. The results indicat...
Article
Food consumption comprises a significant portion of the total environmental impact of households. One way to reduce this impact may be to offer consumers more climate-friendly meal choices, such as when eating out. However, the environmental benefits of such an intervention will depend on not only consumers' liking of the climate-friendlier meals,...
Article
The importance of knowledge for lay people's climate change concerns has been questioned in recent years, as it had been suggested that cultural values are stronger predictors of concern about climate change than knowledge. Studies that simultaneously measured knowledge related to climate change and cultural values have, however, been missing. We c...
Article
Full-text available
Today’s complex and systemic nature of risks has increasingly dissipated the traditional boundaries between risk assessment, risk perception and social coping mechanisms (Renn, 2008). Individuals and societies are now faced with multiple risks in their everyday lives that although being different in nature - environmental, social, economic, … - may...
Article
We conducted a survey among convenient samples of pig farmers (N = 281) in Belgium, France, Germany, Sweden and Switzerland. We identified some significant differences among the five investigated countries (independent variable) regarding farmers’ antimicrobial usage compared to their own country and worries related to pig farming (dependent variab...
Article
Few studies have investigated and compared the acceptance of different energy technologies, hence the need to examine a comprehensive model to explain their acceptance. Moreover, little is known about the role of protected values, that is, values that are extremely important and non-negotiable for a person, in the acceptance of different energy res...
Article
The increasing problem of antibiotic resistance has been related, among other factors, to the extensive use of antibiotics in pig farming. To be able to reduce antibiotic usage in this type of livestock breeding, it may be important to know which internal characteristics of farmers are related to their antibiotic treatment practices, next to the ex...
Article
Abstract Salient events, such as the nuclear accident in Fukushima, can change people's acceptance of a hazardous technology. The aim of the present study was to investigate how people's acceptance of nuclear power relates to their ambivalence and knowledge before and after Fukushima. Additionally, we examined what explains people's change in accep...
Article
Abstract Consumers need information such as nutrition tables to assess the nutritional value of a food product. Although a broad range of studies has examined consumers’ attention, perception and use of nutrition tables, relatively little is known about what types of consumers use what kind of nutrition information. Therefore, using data from the S...
Article
Utilizing a longitudinal study design, the impact of the 2011 accident in Fukushima on acceptance of nuclear power and the evaluation of several scenarios with different percentages of nuclear power were examined. Mail surveys were conducted in the German-speaking part of Switzerland. The first survey took place before the accident in Fukushima (Au...
Article
Major nuclear accidents, such as the recent accident in Fukushima, Japan, have been shown to decrease the public's acceptance of nuclear power. However, little is known about how a serious accident affects people's acceptance of nuclear power and the determinants of acceptance. We conducted a longitudinal study (N= 790) in Switzerland: one survey w...
Article
Consumers influence climate change through their consumption patterns and their support or dismissal of climate mitigation policy measures. Both climate-friendly actions and policy support comprise a broad range of options, which vary in manifold ways and, therefore, might be influenced by different factors. The aims of the study were, therefore, t...
Article
Several studies have unveiled various misconceptions about climate change that the public holds, for instance, confusion about climate change and ozone depletion. However, so far, there has been no uniform and standardized way to measure climate-related knowledge, which complicates comparisons between different countries or samples. To develop an e...
Article
To raise public acceptance of new energy policies, promoting the fairness of the outcomes and of the decision-making procedure has been suggested. Very few studies have examined the role of fairness in public acceptance of rebuilding nuclear power plants. Therefore, using a large mail survey, we investigated the public’s acceptance of the decisio...
Article
For the public to accept new technologies, trust and convictions play an important role. In the present research, we used structural equation modeling to examine an extensive causal model of the role of convictions and trust for the public's protest potential against carbon dioxide capture and storage (CCS) among a large sample of the general popul...
Article
To compare the influence of a food guide's shape on its effectiveness and efficiency to convey nutritional information. A between-subjects experiment was conducted by manipulating the graph's shape (circle, pyramid, or rainbow). Nutrition tasks were used to assess the effectiveness and eye-movement data (number/duration of fixations) to examine the...
Article
Full-text available
Affect appears to have a central role in people?s risk perception and decision-making. It is, therefore, important that researchers and communicators know how risk communication can induce affect or more specific emotions. In this paper, several studies that examined affect-inducing cues presented in and around risk communication are discussed. We...
Article
The aim of the present study is to examine public preferences regarding the characteristics of the three elements of carbon dioxide capture and storage (CCS): capture, pipeline, and storage. A random sample of 139 Swiss citizens received basic information about CCS online and then participated in an experiment. A conjoint measurement of CCS accepta...
Article
Full-text available
Public perception may have a strong impact on the progress of Carbon Dioxide Capture and Storage (CCS). Benefit perception and risk perception are known to be important determinants of public acceptance of CCS. In our study, we examined antecedents of risk and benefit perception of CCS by means of a representative survey and an experimental survey....
Article
This study examined the relationship between the content of spontaneous associations with nuclear power plants and the acceptance of using new-generation nuclear power plants to replace old ones. The study also considered gender as a variable. A representative sample of the German- and French-speaking population of Switzerland (N= 1,221) was used....
Article
The assessment of a food product’s environmental friendliness is highly challenging for consumers because such an assessment requires the consideration of various product characteristics. Furthermore, products often show conflicting features. This study uses a choice task and a questionnaire to examine how consumers judge the environmental friendli...
Article
Food consumption is associated with various environmental impacts, and consumers' food choices therefore represent important environmental decisions. In a large-scale survey, we examined consumers' beliefs about ecological food consumption and their willingness to adopt such behaviors. Additionally, we investigated in more detail how different moti...
Article
Full-text available
Previous studies focused on a limited number of determinants of food label use. We therefore tested a comprehensive model of food label use consisting of sociodemographic, health-related and motivating variables. These three predictor groups were chosen based on the previous literature and completed with new predictors not yet examined in a compreh...
Article
Several countries are currently discussing whether they will rebuild their nuclear power stations in order to continue this type of energy production in the future. The public, with its own opinion about nuclear power stations, has an influential voice in this discussion. As a result, policy makers and nuclear scientists are interested in the publi...

Full-text available
We conducted three studies to investigate how well pictographs communicate medical screening information to persons with higher and lower numeracy skills. In Study 1, we conducted a 2 (probability level: higher vs. lower) x 2 (reference information: yes vs. no) x 2 (subjective numeracy: higher vs. lower) between-subjects design. Persons with higher...
Article
Public perceptions of the benefits and risks associated with carbon dioxide capture and storage (CCS) are important determinants of public acceptance and have a strong impact on the political feasibility of this technology. Communication material aimed at informing the general public about CCS should be tested to find out how it influences perceive...
Chapter
Consumers observe many stimuli in the environment when they choose or consume foods. These external stimuli can be differentiated as having a direct or indirect effect on people. Direct stimuli aim to influence consumers’ perception of a product (e.g., its expected taste) and their food choice. Nutrition labels, for example, aim to help consumers t...
Article
This study aims to evaluate directly how a graphical risk ladder is perceived and how this perception is related to people’s subjective numeracy. Gaze durations and frequencies were used to examine visual attention. Participants (N = 47) appeared to focus on the target risk information, whereas referential information was less attended. Subjective...
Article
Zero-fat products may be good alternatives to regular-fat products for consumers who are watching their health. In a choice experiment, we investigated whether consumers were willing to consume zero-fat products on the basis of nutrition tables and whether numeracy skills affected this decision. We presented respondents with the same two products i...
Article
Carbon Dioxide Capture and Storage (CCS) is assumed to be one of the key technologies in the mitigation of climate change. Public acceptance may have a strong impact on the progress of this technology. Benefit perception and risk perception are known to be important determinants of public acceptance of CCS. In this study, the prevalence and effect...
Article
In the present study we investigated consumers' visual attention to nutrition information on food products using an indirect instrument, an eye tracker. In addition, we looked at whether people with a health motivation focus on nutrition information on food products more than people with a taste motivation. Respondents were instructed to choose one...
Article
In this chapter, an overview of five studies is presented in which we investigated two processes that laypeople may use to perceive risks: associative and cognitive processes. Associative processes are based on gut feelings and instantaneous associations, whereas cognitive processes require more conscious deliberation. These studies were aimed to g...
Article
Laypeople's acceptance and perception of Carbon Dioxide Capture and Storage (CCS) can have an influence on its political feasibility. It is important, therefore, to study how laypeople perceive CCS and which cognitions they hold with respect to this technique. We conducted in-depth interviews with laypeople (N = 16) to explore their mental concepts...
Article
Utilizing a random sample from the general population (N= 257), we examined the effect of the radon risk ladder on risk perception, as qualified by respondents' numeracy. The radon risk ladder provides comparative risk information about the radon equivalent of smoking risk. We compared a risk ladder providing smoking risk information with a risk la...
Article
Consumers often neglect or misinterpret nutrition table information. We argue in this paper that this can be explained by the evaluability principle, which posits that people's evaluation of a product corresponds to a greater degree with the product's actual value when people receive reference information about the product than when they do not get...
Article
Communicating probability information about risks to the public is more difficult than might be expected. Many studies have examined this subject, so that their resulting recommendations are scattered over various publications, diverse research fields, and are about different presentation formats. An integration of empirical findings in one review...

Article
Various incidents in the past, such as the BSE crisis in the UK, have shown that people's perceptions of hazards influence the risk management process. In this literature review, we investigated how people's affective evaluations and their trust in responsible agencies shape risk perception. In addition, we explored the relation between affect and...
Conference Paper
Full-text available
In this paper, we argue that people perceive risks by two types of processes: associative and cognitive processes. Associative processes are based on gut feelings and instantaneous associations with known risks, whereas cognitive processes are relatively more conscious and deliberate. An overview of five studies is presented in which we investigate...
Article
Audiovisual material is increasingly applied in risk communication (e.g., information films on the Internet) to affect the public's risk perception. This study investigated how the sound/footage and text of videos can influence two processes of risk perception: a primary (associative) and a secondary (deliberate) evaluative process. Our main hypoth...
Article
There is a considerable body of knowledge about the way people perceive risks using heuristics and qualitative characteristics, and about how risk information should be communicated to the public. However, little is known about the way people use the perception of known risks (associated risks) to judge an unknown risk. In a first, qualitative stud...
Article
Risk perception is often measured by a direct method, e.g., a questionnaire. This mainly reveals the deliberate evaluation of a risk (a so‐called secondary evaluative process), whereas risk perception can also be based on a first, spontaneous reaction (a primary evaluative process). An indirect test such as the Extrinsic Affective Simon Task (EAST,...

Full-text available
This study tested whether warnings can result in a better working posture with respect to RSI prevention compared with an educational brochure. By using a warning, the information provision on how to prevent RSI can be shorter and only interrupts with the task at hand for a short time. Five conditions were created to compare the effects on position...
