摘要
[目的/意义]社交媒体上充斥着大量的健康谣言,对人民的生命健康构成潜在威胁。对在线健康谣言进行辟谣,探索影响辟谣效果的内在机制有利于引导用户做出正确的健康决策。[方法/过程]研究采用2(信息框架:叙事信息vs.非叙事信息)×3(信息来源:质量来源vs.数量来源vs.对照组)、3(信息框架:叙事信息vs.非叙事信息vs.对照组)×2(话题卷入度:高话题卷入度vs.低话题卷入度)的组间实验设计,从信息框架、信息来源、话题卷入度3个方面探索在线健康谣言辟谣效果的影响机制。[结果/结论]实验结果表明,叙事信息与非叙事信息均正向影响在线健康谣言辟谣效果,且非叙事信息的作用效应大于叙事信息;数量来源与质量来源对在线健康谣言辟谣效果有显著正向影响,且质量来源的效应大于数量来源;信息来源显著调节叙事信息与非叙事信息的作用效应,当信源是数量来源时,叙事信息的辟谣效果更强;当信源是质量来源时,非叙事信息的辟谣效果更强;研究还发现在高话题卷入度组中,非叙事信息组对辟谣效果的影响显著高于叙事信息组,但在低话题卷入度组中,叙事信息和非叙事信息对辟谣效果的影响并无显著差异。
[Purpose/Significance]Social media is full of a large number of health rumors,which pose a potential threat to people's life and health.It is beneficial to guide users to make correct health decisions by refuting online health rumors and exploring the internal mechanism that affects their refuting effects.[Method/Process]This study used the intergroup experimental design:2(Message Framework:narrative vs.non-narrative)×3(Information Source:quality source vs.quantity source vs.control group),and 3(Message Framework:narrative vs.non-narrative vs.control group)×2(Topic Involvement:high topic involvement vs.low topic involvement)to explore the influence mechanism of online health rumor refutation effect from three aspects:message framework,information source and topic involvement.[Result/Conclusion]The experimental results show that both narrative and nonnarrative positively affect the effect of online health rumor refuting,and the effect of nonnarrative is greater than narrative.The effect of quantity source and quality source on online health rumor refuting is significantly positive,and the effect of quality source is greater than quantity source.Information sources significantly moderated the effects of narrative and nonnarrative.When the information source was a quantitative source,the narrative had a stronger rumor refuting effect.When the information source is a quality source,the rumor refuting effect of nonnarrative is stronger.The research also found that in the high topic involvement group,the influence of nonnarrative group on rumor refuting effect is significantly higher than the narrative group,but in the low topic involvement group,the influence of narrative and nonnarrative on rumor refuting effect is not significantly different.
