Abstract As straw reduction campaigns have become ubiquitous, some have worried that adopting the relatively easy behavior of refusing plastic straws will detract from arguably more impactful and important pro-environmental behaviors (PEBs) and policy support. The present study utilized a guilt appeal to encourage reducing straw use (PEB1) and tested spillover effects to a wide range of household and travel PEBs (PEB2s) as well as support for plastic policies and climate change policies. 234 Mturk participants (34% women) completed Time 1 including a survey assessing current PEB practices and policy support and were randomly assigned to the guilt appeal or a control condition and then completed a follow up survey one week later (Time 2) with the same measures. 184 participants also completed an identical survey three months later (Time 3). Results showed evidence of positive relationships between straw use reductions and all PEB2s at Time 2, with several PEB2s showing indirect effects through environmental identity, though no relationships with policy support were found. The guilt manipulation had no effect on straw use and limited our ability to test for spillover effects. By Time 3, many positive relationships between PEB1 and PEB2s had faded. The results underscore the importance of environmental identity in PEB spillover research and also suggest that concerns about negative spillover may be unwarranted.

稻草战争：内疚上诉后的亲环境溢出

摘要 随着减少秸秆的运动变得无处不在，一些人担心采用拒绝塑料吸管的相对容易的行为会减损可以说更有影响力和重要的亲环境行为 (PEB) 和政策支持。本研究利用内疚感来鼓励减少秸秆使用 (PEB1)，并测试对各种家庭和旅行 PEB (PEB2) 的溢出效应以及对塑料政策和气候变化政策的支持。234 名 Mturk 参与者（34% 女性）完成了第一阶段，包括一项评估当前 PEB 实践和政策支持的调查，并被随机分配到有罪上诉或控制条件，然后在一周后（时间 2）完成了一项后续调查（时间 2）措施。三个月后，184 名参与者也完成了相同的调查（时间 3）。结果表明，秸秆使用减少与时间 2 的所有 PEB2 之间存在正相关关系，几个 PEB2 通过环境特性显示出间接影响，但没有发现与政策支持的关系。内疚操纵对稻草的使用没有影响，并限制了我们测试溢出效应的能力。到时间 3，PEB1 和 PEB2 之间的许多积极关系已经消失。结果强调了环境认同在 PEB 溢出研究中的重要性，还表明对负面溢出的担忧可能是没有根据的。内疚操纵对稻草的使用没有影响，并限制了我们测试溢出效应的能力。到时间 3，PEB1 和 PEB2 之间的许多积极关系已经消失。结果强调了环境认同在 PEB 溢出研究中的重要性，还表明对负面溢出的担忧可能是没有根据的。内疚操纵对稻草的使用没有影响，并限制了我们测试溢出效应的能力。到时间 3，PEB1 和 PEB2 之间的许多积极关系已经消失。结果强调了环境认同在 PEB 溢出研究中的重要性，还表明对负面溢出的担忧可能是没有根据的。
