传播学者担心媒体在健康、科学和政治问题上呈现矛盾或冲突的信息，推测这些信息可能对公众的认知、情感和行为产生不利影响。然而，矛盾信息影响的证据基础仍然薄弱。以营养学为例，本研究以这一新兴文献为基础，采用了来自美国成年人全国代表性样本调查的三波面板数据集。我们发现，从电视中接触到相互矛盾的营养信息会增加营养混乱，而从印刷媒体中接触到的营养信息会减少混乱。此外，营养混乱与营养反弹呈正相关，而营养反弹降低了水果和蔬菜消费的参与度。讨论了运动和其他沟通干预措施的影响。
Communication scholars have raised concerns that the media present contradictory or conflicting information on health, science, and political issues, speculating that such information may have adverse effects on public cognitions, affect, and behaviors. However, the evidence base for the effects of contradictory messages remains thin. Using nutrition as a case example, this study builds upon this nascent literature by employing a three-wave panel dataset from a survey with a nationally representative sample of American adults. We found that exposure to contradictory nutrition messages from television increases nutrition confusion, whereas exposure from print media decreases confusion. Moreover, nutrition confusion was positively associated with nutrition backlash, and nutrition backlash decreased engagement in fruit and vegetable consumption. Implications for campaigns and other communication interventions are discussed.
