The attitude model of the theory of reasoned action (TRA) has been applied mainly to predicting the choice of familiar foods; however, the choice of unfamiliar foods may be governed by distinct factors. In the present study, 92 females rated their attitudes and subjective norms about the purchase intentions of two familiar and two unfamiliar cheeses, and the expected and actual pleasantness of them. They also completed the food neophobia scale, which measures the tendency to avoid novel foods. Neophobic persons rated the attitudes and expected and actual taste pleasantness lower than neophilics for all cheeses, except for the most familiar, mild cheese. This suggests that food neophobia also indicates the tendency not only to avoid, but also to dislike novel foods. Before tasting, attitudes and subjective norms together predicted the intent to purchase familiar cheeses better (R2=0.54 and 0.58) than for novel cheeses (R2=0.24 and 0.35); thus, the basic TRA model was not as useful in predicting intent to purchase unfamiliar as familiar cheeses. The predictions especially for the novel cheeses were clearly improved by including expected pleasantness ratings in the model. The usefulness of the food neophobia score as an additional predictor was not clearly supported. Attitudes and subjective norms measured before tasting were poor predictors of purchase intents after tasting, which implies the importance of taste and direct product experience in food choice.
理性行动理论(TRA)的态度模型主要应用于预测对熟悉食物的选择;然而,对不熟悉食物的选择可能受不同因素的支配。在本研究中,92名女性对两种熟悉和两种不熟悉奶酪的购买意愿、态度和主观规范,以及它们预期的和实际的愉悦度进行了评分。她们还完成了食物新恐惧症量表,该量表测量避免新奇食物的倾向。除了最熟悉的温和奶酪外,新恐惧症患者对所有奶酪的态度、预期和实际味觉愉悦度的评分都低于新嗜食者。这表明食物新恐惧症不仅表明了避免新奇食物的倾向,还表明了不喜欢新奇食物的倾向。在品尝之前,态度和主观规范共同对购买熟悉奶酪意愿的预测(R2 = 0.54和0.58)比对新奇奶酪的预测(R2 = 0.24和0.35)更好;因此,基本的TRA模型在预测购买不熟悉奶酪的意愿方面不如预测购买熟悉奶酪的意愿有用。通过在模型中纳入预期愉悦度评分,对新奇奶酪的预测尤其得到了明显改善。食物新恐惧症得分作为额外预测指标的有效性没有得到明确支持。品尝前测量的态度和主观规范对品尝后购买意愿的预测能力较差,这意味着味觉和直接的产品体验在食物选择中很重要。
