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 negation-plus-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 for developing effective corrective strategies.
