Abstract

Highlights: Purchasing behaviour and motivations of coeliac children and parents were studied. Visual attention differed depending on coeliac condition and age using eye-tracking. Besides pleasure, coeliac children also mentioned brand and novelty. Apart from health parents of coeliac children reported trust and economy. Abstract: The aim of this work was to study the behaviour and motivations of coeliac children and their parents when purchasing biscuits. Four groups (n = 30) of participants differing in coeliac condition (coeliac and non-coeliac) and age (children and parents) were studied. Participants were asked to "purchase" biscuits, either for themselves (children) or for their children (parents), in a simulated supermarket aisle that included twelve commercial biscuits (six gluten-free and six regular ones). Eye-tracking technique was used to register visual attention during the purchasing exercise and laddering interviews were used to obtain the self-reported reasons for their choice. The number of fixations received by biscuits and label elements were analysed and most of them varied depending on the coeliac condition, the age or both. In comparison with the non-coeliac children, coeliac children fixated more on the ingredients, gluten-free words and symbols, and fixated less on the biscuit image. Parents of coeliac children put more attention on the ingredients and the certified gluten-free symbol, and less attention on the biscuit image, product name, cartoon, and nutritional information than non-coeliac parents. According to the chains of reasons (attribute-consequence-value), all children looked for pleasure as the final value, but only coeliac children showed interest in the brand and in unknown products they want to try. Parents differed on the attributes linked to health that were certification logo and a short ingredient list for coeliac group, and low sugar or fat contents for non-coeliac one. Trust and economy were relevant only for parents of coeliac children.
