This study examines the factors inflfluencing misinformation correction through fact-checking news using the elaboration likelihood model (ELM). A pretest-posttest experimental design was conducted with 502 Korean participants exposed to fact-checking news on a critical public health issue. By focusing on a non-Western context, this study expands fact-checking research beyond Western settings. To enhance ecological validity, a real-world stimulus?a fact-checking report aired on a major TV channel?was utilized. The study explores how motivational factors (need for cognition, issue involvement) and ability factors (news literacy, daily news consumption) influence elaborative processing and how elaboration mediates misinformation correction through attitude change. Additionally, it investigates the moderating effects of media-source credibility and political alignment between individual and the media source. Findings indicate that elaboration signifificantly mediates the relationship between not only issue involvement (motivational factor) but also news literacy (ability factor) and misinformation correction. However, these mediation effffects weaken as political alignment diverges, reducing the effifficacy of elaboration. These results contribute to a deeper understanding of the theoretical implications of the ELM in the context of misinformation correction through fact-checking news and suggest practical strategies to enhance the effffectiveness of fact-checking interventions in politically polarized environments.
