Abstract

The successful impact of healthy eating campaigns often depends on the extent to which messages are effective in changing attitudes and behaviors over time. The present work proposes that healthy eating campaigns can be designed taking into consideration elaboration and validation processes so that the degree of attitude change is maximally influenced and is consequential. The first set of studies described in this review demonstrates the importance of considering elaboration in determining initial attitudes toward healthy foods as well as the subsequent attitude strength consequences (e.g., stability, prediction of behavior, spreading). The second set of studies focuses on the role of perceived validity of one’s thoughts in the domain of eating as a potential mediator of the persuasion process. These studies include campaigns promoting positive attitudes toward healthy eating (e.g., eating of vegetables and fruits), and interventions oriented to decreasing the intake of unhealthy food (e.g., taxing junk food). We also discuss the role of modality of information presentation (e.g., verbal and visual information vs. direct physical experience) in those studies. Finally, the review offers a tutorial with concrete recommendations that researchers, practitioners and public policy makers can follow in order to predict both short and long-term attitude and behavior changes.

摘要

健康饮食运动的成功影响通常取决于信息在多大程度上有效地改变态度和行为。目前的工作提出，可以在设计健康饮食运动时考虑到详细说明和验证过程，以便最大限度地影响态度变化的程度并产生相应的结果。本综述中描述的第一组研究表明，在确定对健康食品的初始态度以及随后的态度强度后果（例如稳定性、行为预测、传播）时，考虑精细化的重要性。第二组研究侧重于一个人思想的感知有效性在饮食领域作为说服过程的潜在中介的作用。这些研究包括促进对健康饮食（例如，吃蔬菜和水果）的积极态度的运动，以及旨在减少不健康食物摄入量（例如，对垃圾食品征税）的干预措施。我们还讨论了这些研究中信息呈现方式（例如，口头和视觉信息与直接的身体体验）的作用。最后，该评论提供了一个包含具体建议的教程，研究人员、从业者和公共政策制定者可以遵循这些建议来预测短期和长期的态度和行为变化。直接的身体体验）在这些研究中。最后，该评论提供了一个包含具体建议的教程，研究人员、从业者和公共政策制定者可以遵循这些建议来预测短期和长期的态度和行为变化。直接的身体体验）在这些研究中。最后，该评论提供了一个包含具体建议的教程，研究人员、从业者和公共政策制定者可以遵循这些建议来预测短期和长期的态度和行为变化。
