摘　　要：人们的健康观点和行为容易受到错误健康信息的误导,纠正错误健康信息是健康传播、错误信息治理研究的重要议题。论文针对错误健康信息,一方面,在相关理论指导下,考察三种纠正方式(直接否定、详细解释、组合纠正)的纠正效果有无显著差异;另一方面,从启发式信息处理角度出发,探究错误健康信息的来源可信度和图文相关性这两个启发式线索对纠正效果的影响,同时检验初始信任在其中的中介效应。研究发现:组合纠正的效果显著优于单一方式;错误健康信息的高可信度来源和高相关性图文能够降低纠正效果,但对纠正方式的纠正效果的调节作用不显著,且初始信任仅在来源可信度对纠正效果的影响中起部分中介作用。该研究对错误健康信息的治理实践提供了实证支持,为制定有效纠正策略提供了理论依据。Views and behaviors about health are susceptible to misinformation.Correcting health misinformation has become an important issue within health communication and misinformation correction.This study evaluated the efficacy of three intervention approaches in reducing the impact of health misinformation:simple negation,detailed explanation,and negation-plus-explanation.We also explored how heuristic cues,such as source credibility and image-text correlation,might contribute to the formation of misinformed views through the mediation of initial trust.We found that negationplus-explanation interventions were more conducive to belief change than other methods,while health misinformation with high credibility sources and high correlation image-text reduced the corrective effect.Additionally,heuristic cues did not moderate the corrective effect of the correction method,and initial trust only partially mediated the impact of source credibility on the corrective effect.This study provides empirical support for managing health misinformation and lays a theoretical foundation fordeveloping effective corrective strategies.
