摘要

目的在 COVID-19 大流行期间,公众在很大程度上依赖数字媒体来了解最新消息。媒体偏好可能会增加风险认知,但多样化媒体接触的影响仍然未知。基于保护动机理论,本研究旨在探讨数字媒体接触多样性和信息验证如何影响疫苗接种意向。本研究分析了来自中国 837 名受访者的调查数据,考察了数字媒体接触对信息验证的影响,包括对威胁评估、应对评估、疫苗误报信念、主观规范和疫苗信任的影响。研究结果表明,数字媒体接触的多样性增加了威胁评价(感知严重性)和应对评价(反应效能和自我效能),而信息核实只增加了应对评价(反应效能和自我效能)。此外,数字媒体接触的多样性降低了疫苗误报信念。此外,通过反应效能、主观规范和对疫苗的信任的中介作用,数字媒体接触和信息验证与疫苗接种意向相关联。 原创性/价值 本研究是在疫苗接种和健康危机背景下调查媒体接触多样性的首例同类研究。我们的研究结果扩展了 PMT 框架,探讨了作为中介过程前因的主动信息相关行为。此外,我们还研究了作为社会影响因素的错误信息信念、社会规范和信任。我们还讨论了理论和实践意义。

Diversity of digital media exposure, information verification and vaccination intention: an empirical study in China
PurposeDuring the COVID-19 pandemic, the public relied heavily on digital media to stay tuned for the latest update. Media preference could increase risk perceptions, although the influence of diverse media exposure remains unknown. Based on protection motivation theory, this study aims to investigate how digital media exposure diversity and information verification influence vaccination intention.Design/methodology/approachAnalyzing survey data from 837 respondents in China, this study examined the effects of digital media exposure on information verification, including their influences on the threat appraisal, coping appraisal, vaccine misinformation beliefs, subjective norms and trust in vaccines.FindingsResults indicate that diversity of digital media exposure increased threat appraisal (perceived severity) and coping appraisal (response efficacy and self-efficacy), while information verification increased only coping appraisal (response efficacy and self-efficacy). In addition, diversity of digital media exposure decreased vaccine misinformation beliefs. Furthermore, digital media exposure and information verification were linked to vaccination intention via the mediations of response efficacy, subjective norms and trust in vaccines.Originality/valueThis study is the first of its kind to investigate media exposure diversity in the context of vaccination and health crises. Our findings extended the PMT framework by exploring proactive information-related behaviors as antecedents of mediation processes. In addition, we examined misinformation beliefs, social norms and trust as societal influences. Theoretical and practical implications are also discussed.
