    Attitudes - Food choice motives - Food Choices Questionnaire - Food4Me - Intention - Nutrigenomics - Personalised nutrition - Survey

    Objective: The present study explored associations between food choice motives, attitudes towards and intention to adopt personalised nutrition, to inform communication strategies based on consumer priorities and concerns. Design/Setting: A survey was administered online which included the Food Choice Questionnaire (FCQ) and items assessing attitudes towards and intention to adopt personalised nutrition. Subjects: Nationally representative samples were recruited in nine EU countries (n 9381). Results: Structural equation modelling indicated that the food choice motives ‘weight control’, ‘mood’, ‘health’ and ‘ethical concern’ had a positive association and ‘price’ had a negative association with attitude towards, and intention to adopt, personalised nutrition. ‘Health’ was positively associated and ‘familiarity’ negatively associated with attitude towards personalised nutrition. The effects of ‘weight control’, ‘ethical concern’, ‘mood’ and ‘price’ on intention to adopt personalised nutrition were partially mediated by attitude. The effects of ‘health’ and ‘familiarity’ were fully mediated by attitude. ‘Sensory appeal’ was negatively and directly associated with intention to adopt personalised nutrition. Conclusions: Personalised nutrition providers may benefit from taking into consideration the importance of underlying determinants of food choice in potential users, particularly weight control, mood and price, when promoting services and in tailoring communications that are motivationally relevant.

    Understanding intentions to purchase bio-based products : The role of subjective ambivalence

    Benefit - Bio-based product - Emotion - Intention - Risk - Subjective ambivalence - Sustainability and consumer

    This article aims to explore whether subjective ambivalence increases the understanding of consumers' intentions to buy bio-based products. Subjective ambivalence is the aversive feeling that accompanies evaluations containing both negative and positive elements. Two studies (N = 1851) in six European countries show that subjective ambivalence increases the explained variance beyond vested exploratory variables: emotions and variables of the theory of planned behaviour. This finding implies that the intention to purchase bio-based products is based on more than cognitive deliberations or emotions; it is also associated with an aversive feeling of subjective ambivalence. Additionally, this article divides attitudes into risks and benefits associated with bio-based products and thereby shows that subjective ambivalence strengthens the association between risks and intentions and not that between benefits and intentions. Highly ambivalent consumers are more sensitive to risks than less ambivalent consumers, whereas for the sensitivity to benefits there are no differences between individuals with high and low ambivalence. In conclusion, to understand public opinion regarding bio-based products, it is important to comprehensively monitor and understand ambivalence.

    Intention of dog owners to participate in rabies control measures in Flores Island, Indonesia

    Control measures - Dog owners - Flores Island - Intention - Rabies

    The success of a rabies control strategy depends on the commitment and collaboration of dog owners. In this study the theory of planned behaviour (TPB) was used to identify the factors, which are associated with the intention of dog owners to participate in rabies control measures in the Manggarai and Sikka regencies of Flores Island, Indonesia. Questionnaires were administered to 450 dog owners from 44 randomly selected villages in the two regencies. Ninety-six percent of the dog owners intended to participate in a free-of-charge vaccination campaign. The intention decreased to 24% when dog owners were asked to pay a vaccination fee equal to the market price of the vaccine (Rp 18.000 per dose = US$2). Approximately 81% of the dog owners intended to keep their dogs inside their house or to leash them day and night during a period of at least three months in case of an incidence of rabies in the dog population within their village. Only 40% intended to cull their dogs in case of a rabies incident within their village. Using multivariable logistic regression analysis, the attitude item 'vaccinating dogs reduces rabies cases in humans', and the perceived behavioural control items 'availability of time' and 'ability to confine dogs' were shown to be significantly associated with the intention to participate in a free-of-charge vaccination campaign. The attitude item 'culling dogs reduces rabies cases in humans' was significantly associated with the intention to participate in a culling measure. The attitude item 'leashing of dogs reduces human rabies cases' and perceived behavioural controls 'availability of time' and 'money to buy a leash' were associated with the intention to leash dogs during a rabies outbreak. As the attitude variables were often significantly associated with intention to participate in a rabies control measure, an educational rabies campaign focusing on the benefit of rabies control measures is expected to increase the intention of dog owners to participate in future rabies control measures. The significant association between perceived behavioural controls and intention to participate points to other relevant policy interventions. Providing dog owners with a skill to confine dogs and creating a subsidy program for the vaccine and leash costs, by involving non-governmental organisations or charitable organisations, may be useful policy interventions. Moreover appropriate time management, such as implementing vaccination campaigns during the weekend, could increase the intention to participate in vaccination campaigns, by relaxing the constraints on the availability of dog owners' time.

    The effects of practicing registration of organ donation preference on self-efficacy and registration intention : An enactive mastery experience

    Adolescents - Intention - Organ donation - Registration - Self-efficacy

    To evaluate an intervention to increase self-efficacy intentions to register organ donation preference, a Randomized Controlled Trial was conducted among 242 Dutch high-school students aged 15 to 18 years. On the basis of Social Cognitive Theory, practicing with a standard registration form (according to the Dutch system) was expected to increase the intention to register an organ donation preference through increasing self-efficacy. The participants in the experimental group practiced how to complete a registration form while the control group did not receive an intervention. Students in both groups completed a self-administered questionnaire before and after the intervention took place. The results showed that self-efficacy and intentions to register organ donation preferences at post-test were significantly higher in the intervention group.
