In 2020, Twitter launched a new strategy dubbed ‘prebunking’ in hopes of pre-emptively countering false information about voting by mail and election results. Prebunking was touted as a potential solution; however, little empirical research has tested the strategy to examine its effectiveness towards disinformation in the realm of public relations. Exploring PR-based disinformation attacks as a paracrisis, the purpose of this online quasi-experimental design study (N = 965) was to investigate the effects of an attack and how prebunking strategies, grounded in inoculation theory, can protect organizational outcomes (i.e., reputation and credibility) by interweaving positive psychology. In addition to examining effects on attitudinal components, this study also inspected dimensions of social amplification to determine if prebunking messages can thwart the spread of disinformation via Facebook. Findings provide insight into advancing the conceptual framework of proactive disinformation responses for crisis communication by demonstrating the success of using prebunking with autonomy support and explicit details to thwart adverse effects of disinformation.

2020 年，Twitter 推出了一项名为“prebunking”的新策略，希望能够先发制人地打击有关邮寄投票和选举结果的虚假信息。Prebunking 被吹捧为一种潜在的解决方案。然而，很少有实证研究测试该策略以检查其在公共关系领域对虚假信息的有效性。探索基于 PR 的虚假信息攻击作为一种平行危机，该在线准实验设计研究的目的 ( N= 965) 是为了调查攻击的影响以及基于接种理论的预铺位策略如何通过交织积极心理学来保护组织成果（即声誉和可信度）。除了检查对态度成分的影响之外，这项研究还检查了社会放大的维度，以确定预置信息是否可以阻止虚假信息通过 Facebook 传播。调查结果通过展示使用具有自主支持和明确细节的 prebunking 来阻止虚假信息的不利影响的成功，为推进针对危机传播的主动虚假信息响应的概念框架提供了见解。
