新冠肺炎疫情下的事實查核：風險感知、自我效能感與公民線上推理能力的角色

Fact-checking in the context of the COVID-19 pandemic: The dynamics between risk perception, self-efficacy, and civic online reasoning

結合O1-S-O2-R模型及保護動機理論，本研究以新冠肺炎疫情為背景，探討影響事實查核行為意圖的因素。運用網路調查資料（N = 1,248），本研究發現社群媒體和事實查核行為意圖同時具有直接關係及間接關係。自我效能感是顯著的中介變項，但風險感知和事實查核行為意圖無關，也非顯著之中介變項。此外，公民線上推理能力和社群媒體使用、自我效能感皆具有交互作用關係，此結果對不實訊息相關防制策略的擬定具有一定貢獻。

Drawing upon the O1-S-O2-R and the protection motivation models, this study examines the factors shaping people’s fact-checking behavioral intentions, focusing on the mediation role of self-efficacy and risk perception. This study also investigates the moderating effect of civic online reasoning. To date, research about the impact of social media use on fact-checking behavioral intentions is scarce, especially in the context of the COVID-19 pandemic. Employing an online survey of Taiwanese adults, collected between July 27 and August 3, 2021 (N = 1,248), this study conducted a moderated mediation analysis. The results indicated that social media exerts both a direct and an indirect positive effect on fact-checking behavioral intentions. Self-efficacy, but not risk perception, serves as the mediator of this relationship. Civic online reasoning moderated the effects of social media use and self-efficacy on fact-checking behavioral intentions. Implications of the findings will be discussed.
