摘　　要：“数字健康”时代,公众基于在线健康信息进行“网络自诊”的行为大量增长,在线健康信息质量的不确定性增加了人们的健康焦虑并诱发网络疑病症。研究在线健康信息质量对网络疑病症的影响,可以为在线健康信息治理提供参考。本文从在线健康信息质量视角出发,探索论据质量与信息源可靠性对网络疑病症的作用机制。通过问卷调查收集386份有效数据,并借助SmartPLS软件进行数据分析与模型检验。结果表明,在线健康信息的论据质量和信息源可靠性显著增强了用户的感知不确定性与健康焦虑,且感知不确定性与健康焦虑是导致网络疑病症产生的共同影响因素。此外,在论据质量和信息源可靠性与网络疑病症的关系中,感知不确定性和健康焦虑发挥中介效应。同时,在感知不确定性与网络疑病症的关系中,健康焦虑也起到中介作用。In the era of"digital health",there has been a significant increase in the public's behavior of"Internet self-diagnosis"based on online health information.The uncertainty in the quality of online health information has heightened health anxiety and led to the emergence of cyberchondria.Understanding the impact of online health information quality on cyberchondria can offer valuable insights for improving online health information governance.This study investigates the mechanisms through which argument quality and source credibility affect cyberchondria from the perspective of online health information quality.We collected 386 valid responses through a questionnaire survey and performed data analysis and model testing with SmartPLS software.The results indicate that both the argument quality and source credibility significantly enhance users'perceived uncertainty and health anxiety,which are common factors contributing to the cyberchondria.Additionally,perceived uncertainty and health anxiety mediate the relationship between argument quality,source reliability,and cyberchondria.Furthermore,health anxiety serves as a mediator in the relationship between perceived uncertainty and cyberchondria.
