    Antimicrobial-resistant bacteria in food: Which behaviour change strategies increase consumers’ risk awareness and preventive food-handling behaviour?
    (Taylor & Francis, 2021) Freivogel, Claudia; Visschers, Vivianne [in: Health Psychology and Behavioral Medicine]
    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 action process approach (HAPA). We tested techniques that are expected to increase knowledge, risk perception, and positive outcome expectancy (Study 1) as well as those that increase planning and coping self-efficacy (Study 2) in two randomised control trials.Methods In Study 1 (N?=?328), a 2x2 between-subject design was employed to investigate the effects of an educational video about the spread of antimicrobial-resistant bacteria and a personalised risk message on knowledge, risk perception, outcome expectancy and consequently on intention regarding safe food-handling behaviour. In Study 2 (N=129), we used a 2x2 design to examine to what extent goal setting (implemented vs. not implemented) and time (pre- vs. post-test) affected planning, coping self-efficacy, and preventive food-handling behaviour.Results In Study 1, we found that the video increased knowledge and the perceived susceptibility of risk compared to the control video. We found no increase on the dependent variables after receiving the personalised risk message. In Study 2, goal setting significantly improved safe food-handling behaviour compared to the control condition. Moreover, participants in the goal-setting condition showed more planning of safe food-handling measures and of dealing with emerging barriers than participants in the control condition.Conclusions These findings demonstrate that the delivery of an educational video on the spread of antimicrobial-resistant bacteria is a useful strategy to increase risk awareness, whereas goal setting presents a promising approach to improve food-handling behaviour. Following the HAPA, an additional effective behaviour change technique is required that decreases negative outcome expectancies and improves coping self-efficacy, thereby further improving intention and behaviour.

    Exposure pathways to antimicrobial resistance at the human-animal interface—A qualitative comparison of Swiss expert and consumer opinions
    (Frontiers, 2020) Lechner, Isabel; Freivogel, Claudia; Stärk, Katharina D. C.; Visschers, Vivianne [in: Frontiers in Public Health]
    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 pathways, Swiss experts and consumers were interviewed about their opinions on the risks of transmission of AMR. Opinions of experts and consumers were then qualitatively compared and the main gaps identified. The results revealed that Swiss consumers had several misconceptions regarding the sources and transmission of AMR, and that they in particular underestimated the importance of poultry meat and pets as a potential source of AMR. Furthermore, high uncertainty was noted in experts regarding the prevalence of AMR in pets and the potential of transmission to their owners. Consequently, awareness of AMR transmission pathways should be increased among consumers to overcome common misconceptions, which will help reduce the risk of transmission. Further research is needed to better understand the pets' potential to harbor and transmit AMR to their owners, and to identify most effective methods to increase risk awareness in consumers as well as intervention strategies promoting consumer behaviors to mitigate AMR transmissions at the human-animal interface.

    Erklärungsvideo Antibiotikaresistenzen - Haustiere
    (2020) Freivogel, Claudia; Visschers, Vivianne
    Erklärungsvideo für Konsument*Innen über die Verbreitung antimikrobieller Resiztenzen durch den Kontakt mit Haustieren. Das Video zeigt welche Massnahmen ergriffen werden können, um die Übertragung resistenter Keimen zu reduzieren. Das Video wurde zusammen mit Pascale Küng, Claudia Wirth, Vanessa Feck und Stefan Holaus entwickelt. Educational video for consumers about the transmission of antimicrobial-resistant bacteria through pet contact and care. The video explains behavioral measures that prevent the spread of resistant bacteria. The video was developed together with Pascale Küng, Claudia Wirth, Vanessa Feck and Stefan Holaus.
