Celebrity disclosures and narratives are popular strategies in health promotion. However, less is known about their joint effects and the mechanisms through which they function. A 2 (narrative type: celebrity vs. layperson) x 2 (personal relevance: low vs. high) online experiment (N = 248) tested the impact of different narrative types in increasing awareness about prescription opioid abuse. Results indicated that a celebrity narrative is more persuasive than its layperson counterpart. Also, personal relevance toward opioid addiction moderated the influence of narrative type. Celebrity narratives evoked more positive attitudes toward opioid prevention and greater behavioral compliance intentions with the recommended action for low-relevance individuals. Transportation and identification mediated the effects of celebrity narratives on participants’ issue attitudes and behavioral intentions, but only for low-relevance individuals. Practically, the data suggest that incorporating celebrities in health narratives about opioid addiction prevention facilitates behavioral compliance, especially for individuals to whom a pressing health issue like opioid misuse is currently of low relevance.

名人披露和叙述是健康促进的流行策略。然而，人们对它们的联合作用以及它们发挥作用的机制知之甚少。A 2（叙事类型：名人与外行）x 2（个人相关性：低与高）在线实验（N = 248）测试了不同叙事类型对提高对处方阿片类药物滥用的认识的影响。结果表明，名人的叙述比外行的叙述更有说服力。此外，与阿片类药物成瘾的个人相关性缓和了叙事类型的影响。名人叙述唤起了对阿片类药物预防的更积极态度和对低相关性个体的推荐行动的更大行为依从性意图。交通和认同在名人叙事对参与者的问题态度和行为意图的影响中起中介作用，但仅适用于低相关性的个体。实际上，数据表明，将名人纳入关于预防阿片类药物成瘾的健康叙述有助于行为依从性，
