鉴于需要减少粮食浪费，向个人传达信息的基于信息的干预活动至关重要，可能是解决方案的一部分。然而，这些信息的主题一直存在学术争论。尽管缺乏经验证据，但学者和实践者最近关注的是环境信息，尽管传统上，其他人主张以品味或财务为导向的信息。我们通过两个实验，共计1656名参与者，为解决这场辩论作出了贡献。我们研究了以环境和口味为导向的信息如何影响减少食物浪费和计划膳食的行为意愿（实验1），以及以环境和经济为导向的信息如何影响减少食物浪费的兴趣（实验2）。在实验1中，我们发现，与控制条件相比，将膳食计划与应对气候变化联系起来的信息激发了更多的未来膳食计划意愿和更普遍的减少食物浪费的意愿。我们还发现，与将饮食计划与美味食物联系起来的信息相比，环保信息在提高减少食物浪费的总体意愿和提高未来饮食计划意愿方面更有效。在实验2中，我们发现环境信息比没有信息更能促进人们对减少食物浪费的兴趣，并且与传达食物浪费的经济负担的信息一样有效。我们讨论了对未来干预运动和研究的影响。
Given the need to reduce food waste, information-based intervention campaigns that present messages to individuals are crucial and likely part of the solution. However, the subject matter of these messages has been under scholarly debate. Although empirical evidence is lacking, scholars and practitioners have recently focused on environmental messages even though, traditionally, others have advocated for taste- or financially-oriented messages. With two experiments, totaling 1,656 participants, we contribute to the resolution of this debate. We examined how environmental and taste-oriented messages affect behavioral intentions to reduce food waste and to plan meals (Experiment 1) and how environmental and financially-oriented messages affect interest in food waste reduction efforts (Experiment 2). In Experiment 1, we found that a message linking meal planning to tackling climate change elicited more future meal planning intentions and more general intentions to reduce food waste than the control condition. We also found that an environmental message was more effective in increasing general intentions to reduce food waste and as effective in increasing future meal planning intentions, than a message that linked meal planning to tasty food. In Experiment 2, we found that an environmental message promoted more interest in food waste reduction efforts than no message and was as effective as a message that conveyed the financial burden of food waste. We discuss implications for future intervention campaigns and research.
