Based on the elaboration likelihood model,the current study takes fact-checking interruption as the research object,and explores the impact of two fact-checking mechanisms,source rating and content rating,on users'perceived information credibility and subsequent information participation behavior.The moderating effect of prior knowledge is also investigated.Through an online scenario-based experiment in-volving 202 subjects,the present study found that both source and content rating mechanisms positively affect perceived credibility.Subsequently,perceived credibility has a positive impact on reading,liking,posting supportive comments and forwarding information,but has had no significant impact on posting rebutted com-ments.Prior knowledge has a negative moderating effect on the relationship between content rating and per-ceived credibility,but has no significant moderating effect on the relationship between source rating and per-ceived credibility.The present study enriches the literature and theories related to the credibility of health in-formation in social media and offers managerial insights for the development of a social media information in-tervention mechanism.
