[Purpose/significance] Conflict health information is an important interfering factor in the health informa⁃tion dissemination for the new elderly people. Clarifying the influencing mechanism and role path of conflict health in⁃formation on resistance to persuasion among the new elderly people has important reference value for designing effec⁃tive health information dissemination intervention measures. [Method/process] Based on the person-environment fit theory, this study constructed a multiple serial mediation model to examine the effects of conflict health information on resistance to persuasion. Empirical analysis was conducted through a 2 (conflict health information: conflict vs. nonconflict)×2 (evidence type: non-narrative vs. narrative) between-subjects design, while multi-group analysis and posthoc test was employed to explore the differential effects across different evidence types. [Result/conclusion] Conflict health information indirectly influences resistance to persuasion among the new elderly people; conflict health informa⁃
tion positively affects the information supplies-information needs mismatch and the information demands-information abilities mismatch, and two types of mismatches both result in cognitive dissonance and perceived low efficiency among the new elderly people, which in turn result in resistance to persuasion; compared with non-narrative conflict health in⁃formation, narrative conflict health information result in stronger resistance to persuasion among the new elderly peo⁃ple, and the post-hoc test further showed that narrative conflict health information directly result in active resistance among the new elderly people.
