Most research on consumer attitudes does not consider that attitudes are likely influenced by people with whom we have some relationship even though socioeconomic, psychological and political theories recognize the importance of referent individuals' opinions in attitude formation. Knowledge on the role of referent individuals' opinions in attitude formation could improve the understanding of consumer acceptance of foods frequently associated with health or other concerns. This article examines the association of attitudes towards genetically modified (GM) crops and foods between young adults and their referent individuals using data collected in 2016 via surveys from the Czech Republic, Russia and Ukraine. Loglinear models of cell counts in contingency tables reveal a positive association of GM food attitudes between young adults and their referent individuals. This association was stronger in Russia and the Czech Republic than it was in Ukraine and stronger between female young adults and their referent individuals than between males and their referent individuals. Concordance in GM food attitudes with mothers is significantly stronger than concordance with best friends but not significantly different from concordance with fathers.
大多数关于消费者态度的研究都没有考虑到态度可能会受到我们与之有某种关系的人的影响，尽管社会经济、心理和政治理论都认识到参照个体的意见在态度形成中的重要性。了解参照个体意见在态度形成中的作用，可以增进对消费者对那些经常与健康或其他问题相关的食品的接受程度的理解。本文使用 2016 年捷克共和国、俄罗斯和乌克兰通过调查收集的数据，研究了年轻人与其参照个体之间对转基因（GM）作物和食品的态度之间的关系。列联表的细胞计数的对数线性模型显示，年轻人与其参照个体之间的 GM 食品态度呈正相关。这种相关性在俄罗斯和捷克共和国比在乌克兰更强，在女性年轻人与其参照个体之间比在男性年轻人与其参照个体之间更强。与母亲 GM 食品态度的一致性显著强于与最好朋友的一致性，但与与父亲的一致性没有显著差异。
