[目的/意义]冲突性健康信息是新老年人健康信息传播的重要干扰因素，厘清冲突性健康信息对新老年人信息说服抵制的影响机制和作用路径，对设计有效的健康信息传播干预措施具有重要的参考价值。[方法/过程]基于“个人—环境匹配理论”，构建冲突性健康信息对信息说服抵制的多重链式中介模型。通过“2 (冲突性健康信息：冲突vs.无冲突)×2(证据类型：非叙事型vs.叙事型)”的组间实验进行实证分析，并通过多群组分析和事后检验探究不同证据类型的差异化影响。[结果/结论]冲突性健康信息间接影响新老年人信息说服抵制；冲突性健康信息正向影响信息供给—信息需求不匹配和信息要求—信息能力不匹配，两种不匹配引发新老年人的认知失调和感知低效能，进而导致信息说服抵制；相较于非叙事型冲突性健康信息，叙事型冲突性健康信息引发了新老年人更强的信息说服抵制，事后检验进一步表明叙事型冲突性健康信息直接引发了新老年人的主动抵制。

[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.
