Research on the Backfire Effect of Corrective Health Information Under the Information Source Credibility:A Study of Controlled Experiments
[Purpose/Significance]Exploring the backfire effect of corrective health information can provide theoretical support and strategic suggestions for the government and online health communities to improve the efficiency of health information use.[Method/Process]The experiments on worldview backfire effect and famil-iarity backfire effect were designed to test the relationships among perceived threat,perceived information quality,perceived novelty,and correction divergence.The mediating effect of negative emotions and the moderating effect of information source credibility were also tested by controlled experiments.[Result/Conclusion]It is found that the backfire effect of corrective health information does exist.Perceived threat can positively influence correction divergence,and negative emotions play a mediating role.Besides,information source credibility can negatively moderate the influence of perceived threat on correction divergence.The backfire effect is more prominent for the corrective health information on daily diet.Perceived information quality has a negative impact on correction diver-gence.Perceived novelty is not an influencing factor in the familiarity backfire effect.Furthermore,the information source credibility has no significant moderating effect on the correction divergence.
