摘要: 在数字时代，在线评论作为网络社交媒体上的重要互动行为，使公众能够参与新闻事件讨论，并影响其对新闻可信度的判断。本研究基于MAIN模型、情绪感染理论、从众效应和负性偏向效应，采用单因素被试间实验设计，自变量为在线评论效价比例，包括3:7、4:6、5:5、6:4、7:3 (正性评论:负性评论)五个水平，因变量为新闻可信度。研究通过问卷星模拟社交媒体阅读新闻情境，共收集200名有效被试数据。结果发现：评论效价比例对新闻可信度影响显著(F = 8.230，p < 0.001，η2 = 0.144，中等效应)，表明该影响兼具统计显著性与实际意义。随着正性评论比例升高或负性评论比例降低，新闻可信度总体升高；反之降低，但并非所有比例变化均显著。5:5是评论效价比例变化中的关键点，3:7、4:6、7:3条件下的新闻可信度与5:5条件存在显著差异。研究表明，5:5可作为网络舆情预警线，为网络舆情监管、健康新闻传播和和谐网络环境建设提供依据。
Abstract: In the digital age, online comments, as an important interactive behavior on social media, allow the public to participate in news discussions and affect their judgments of news credibility. Based on the MAIN model, emotional contagion theory, herd effect, and negativity bias, this study adopted a one-way between-subjects experimental design. The independent variable was online review valence ratio, including five levels: 3:7, 4:6, 5:5, 6:4, and 7:3 (positive comments:negative comments). The dependent variable was news credibility. A total of 200 valid participants were recruited through an online questionnaire to simulate a social media news-reading context. The results showed that review valence ratio significantly affected news credibility (F = 8.230, p < 0.001, η2 = 0.144, moderate effect). It indicates that this effect is both statistically significant and of practical significance. As the proportion of positive comments increased or negative comments decreased, news credibility generally increased; the opposite pattern decreased credibility, but not all changes were significant. The 5:5 ratio was a key point, and credibility under 3:7, 4:6, and 7:3 differed significantly from that under 5:5. The 5:5 ratio can serve as an early warning line for online public opinion, providing evidence for online public opinion supervision, health news communication, and the construction of a healthy online environment.
