Informed by the notion of spillover effects between two phenomena, this study examines how differences in prior attitudes would influence the relationships posited by the influence of presumed media influence (IPMI) model. Specifically, this study examines how pre-existing favorable and unfavorable attitudes toward genetically modified (GM) food are associated with audiences’ intention to consume nano-enabled food. The results of a nationally representative survey with 1,000 respondents found general support for the IPMI from media attention to behavioral intentions, through attitude and social norms. Further, a multigroup analysis of the IPMI provided evidence for differences in the IPMI effects between the audiences with favorable and unfavorable pre-existing attitudes toward GM food. These results contribute to a stronger theoretical understanding of the IPMI in terms of how pre-existing attitudes toward a preceding food technology can have a spillover effect on how audiences make decisions regarding a newer food technology.

过去的争论，对纳米食品的新影响：基于对转基因食品态度溢出效应的假定媒体影响模型的多组比较

本研究以两种现象之间的溢出效应概念为依据，研究了先前态度的差异如何影响假定媒体影响 (IPMI) 模型的影响所假设的关系。具体而言，这项研究调查了先前存在的对转基因 (GM) 食品的有利和不利态度如何与观众食用纳米食品的意图相关联。一项涉及 1,000 名受访者的全国代表性调查的结果发现，从媒体关注到行为意图，通过态度和社会规范，对 IPMI 的普遍支持。此外，对 IPMI 的多组分析提供了证据，证明对转基因食品持有有利和不利预先存在态度的受众之间的 IPMI 效应存在差异。
