在流行病危机期间，公众在社交媒体上收到的一些信息是错误的。目的：（1）探讨卫生组织如何纠正社交网络上支持接种和犹豫接种两类人群的麻疹疫苗接种错误信息;（2）探讨两类人群的反应类型（亲疫苗接种，犹豫不决）错误信息纠正;和（3）检查这两个亚组的可靠性，满意度，自我效能和intentions.MethodsA对照实验与参与者随机分为两个条件下的错误信息纠正的效果。在这两种实验条件下，都出现了送孩子上幼儿园的两难选择，随后在Facebook上发表了相同的帖子，表达了孩子母亲的担忧。在第三阶段，卫生组织的纠正分为两种情况：情况1 -普通信息纠正，情况2-建议的（基于理论的）信息纠正，主要是透明地传达信息和解决公众的关切。研究对象为海法大学社会福利与健康科学学院的243名研究生。结果卫生部在控制条件和实验条件下进行的信息校正的可靠性水平存在统计学显著性差异（sig
BackgroundDuring epidemic crises, some of the information the public receives on social media is misinformation. Health organizations are required to respond and correct the information to gain the public's trust and influence it to follow the recommended instructions.Objectives(1) To examine ways for health organizations to correct misinformation concerning the measles vaccination on social networks for two groups: pro-vaccination and hesitant; (2) To examine the types of reactions of two subgroups (pro-vaccination, hesitant) to misinformation correction; and (3) To examine the effect of misinformation correction on these two subgroups regarding reliability, satisfaction, self-efficacy and intentions.MethodsA controlled experiment with participants divided randomly into two conditions. In both experiment conditions a dilemma was presented as to sending a child to kindergarten, followed by an identical Facebook post voicing the children mothers' concerns. In the third stage the correction by the health organization is presented differently in two conditions: Condition 1 -common information correction, and Condition 2-recommended (theory-based) information correction, mainly communicating information transparently and addressing the public's concerns. The study included (n = 243) graduate students from the Faculty of Social Welfare and Health Sciences at Haifa University.ResultsA statistically significant difference was found in the reliability level attributed to information correction by the Health Ministry between the Control condition and Experimental condition (sig
