What types of public health messages are effective at changing people's beliefs and intentions to practice social distancing to slow the spread of COVID-19? We conducted two randomized experiments in summer 2020 that assigned respondents to read a public health message and then measured their beliefs and behavioral intentions across a wide variety of outcomes. Using both a convenience sample and a pre-registered replication with a nationally representative sample of Americans, we find that a message that reframes not social distancing as recklessness rather than bravery and a message that highlights the need for everyone to take action to protect one another are the most effective at increasing beliefs and intentions related to social distancing. These results provide an evidentiary basis for building effective public health campaigns to increase social distancing during flu pandemics.
哪些类型的公共卫生信息能有效地改变人们的信念和意图，使其采取社交隔离措施以减缓 COVID-19 的传播？我们在 2020 年夏天进行了两项随机实验，将受访者分配阅读一条公共卫生信息，然后测量他们在各种结果上的信念和行为意图。我们使用便利样本和一项具有全国代表性的美国人预注册复制实验，发现将不进行社交隔离重新定义为鲁莽而非勇敢，以及强调每个人都需要采取行动来保护彼此的信息，对于增加与社交隔离相关的信念和意图最为有效。这些结果为在流感大流行期间制定有效的公共卫生运动以增加社交隔离提供了证据基础。
