Tailoring Can Improve Consumers’ Hygienic Food-Handling Behavior to Reduce the Transmission Risk of Antimicrobial-Resistant Bacteria through Food
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 handling against the spread of antimicrobial-resistant bacteria through foods in a longitudinal rand…
Exposure Pathways to Antimicrobial Resistance at the Human-Animal Interface—A Qualitative Comparison of Swiss Expert and Consumer Opinions
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 at reducing the transmission of AMR from animal sources to humans. To identify the most relevant pat…
Understanding the Underlying Psychosocial Determinants of Safe Food Handling among Consumers to Mitigate the Transmission Risk of Antimicrobial-Resistant Bacteria
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 food handling by consumers. Data were collected from a representative sample of consumers belonging to…

Knowledge as a driver of public perceptions about climate change reassessed
Does environmental friendliness equal healthiness? Swiss consumers’ perception of protein products
Public Perception of Climate Change
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 conducted a mail survey in the German‐speaking part of Switzerland ( N = 1,065). Results suggested th…
Judgments under uncertainty
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. Previous studies have shown that people are ambiguity averse when comparing a univocal risky option wit…
Does better for the environment mean less tasty? Offering more climate-friendly meals is good for the environment and customer satisfaction
How a Nuclear Power Plant Accident Influences Acceptance of Nuclear Power
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 was done five months before and one directly after the accident in Fukushima. We assessed acceptanc…

The role of health-related, motivational and sociodemographic aspects in predicting food label use
Objective 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 comprehensive study of frequency of label use. Design We sent questionnaires to a random sample o…
Affect-inducing risk communication
Affect appears to have a central role in peoples 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 thereby distinguish between integral affect induction, meaning through the risk message, and incident…
Eating green. Consumers’ willingness to adopt ecological food consumption behaviors
Health motivation and product design determine consumers’ visual attention to nutrition information on food products
Objective 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. Design Respondents were instructed to choose one of five cereals for either the kindergarten (health motivation) or the student caf…
How do people perceive graphical risk communication? The role of subjective numeracy
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 numeracy was negatively correlated with total watching time and the absolute number of gaze events. …
When reduced fat increases preference. How fat reduction in nutrition tables and numeracy skills affect food choices
Audiovisual risk communication unravelled
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 hypothesis was that the sound/footage of a video would particularly influence the primary evaluative proce…
An Associative Approach to Risk Perception
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, De Houwer, 2003 De Houwer, J. 2003. The Extrinsic Affective Simon Task. Experimental Psychology, 50…
