本研究旨在分析预先干预对个体感知与行为意愿两个维度的相关变量的作用机制,并比较不同预先干预方式的效果差异.借助双盲实验法,构建对照组VS.事实接种VS.逻辑接种的组间对照实验,共回收 182 份有效数据,并通过问卷采集用户感知与行为意愿数据.通过单因素方差分析检验预先干预的影响机制,以及多重比较分析不同干预方式的作用效果.研究结果表明,失真健康信息的预先干预对个体感知和行为意愿有显著影响.在感知维度,预先干预能够显著降低个体的感知威胁、失真健康信息的感知共识、感知可信度;在行为维度,预先干预能够有效降低个体的失真健康信息分享意愿,但对新冠疫苗的接种意愿影响不大.此外,事实接种与逻辑接种的作用效果无显著差异.本研究拓展了预先干预的应用场景与作用机制,可为确定预先干预在失真健康信息治理中的可行性与有效性提供依据.
An Empirical Study of the Effects of a Prebunking of Health Misinformation on In-dividuals'Perceptions and Behavioral Intentions
This study aims to analyze the mechanisms of prebunking's impact on two specific dimensions(i.e.,individual perception and behavioral intention)and compare the efficacy of different prebunking strat-egies.The hypotheses were tested in a double-blind experimental design,wherein 182 participants were randomly assigned to a fact-based inoculation or a logic-based inoculation or a control group.Specifically,we use one-way ANOVA to test the mechanism of the effect of the pre-intervention and use multiple compari-son analysis to test the effect of different interventions.The results indicate that prebunking have a significant impact on individual perceptions and behavioral intentions.In the perception dimension,prebunking substan-tially reduces individuals'perceived threat,perceived consensus,and perceived credibility of health misin-formation.In the behavioral intention dimension,while prebunking effectively reduces individuals'sharing likelihood of health misinformation,it has little impact on their willingness to vaccinate against COVID-19.Furthermore,no significant difference was observed between the group of fact-based and logic-based inocu-lations.This study broadens the application scenarios and mechanisms of prebunking,offering evidence for assessing its feasibility and efficacy in the governance of health misinformation.
