[目的/意义]调查健康焦虑人群网络健康信息搜索行为的水平与特征，探讨健康焦虑对网络健康信息搜
索行为的影响。[方法/过程]2021年1月30日至2月12日，通过方便抽样向长沙市居民发放788份匿名问卷，使用
躯体症状严重程度量表（PHQ-15）、网络健康信息搜索行为量表（OHIB）、无法容忍不确定性量表（IUS）和健康焦
虑量表（SHAI）等收集用户信息，最终获得有效问卷699份，回收率为88.7%。对收集到的数据进行描述性统计、
方差分析、相关性分析和因子分析，构建结构方程模型进行假设验证。[结果/结论]本研究中①健康焦虑用户的
SHAI得分为22.94±6.99分，搜索行为得分为3.25±0.80分。②健康焦虑用户OHIB得分与HA总得分及患病可能
性、负面结果维度得分（r=0.117-0.184，P＜0.05）存在正相关关系。③健康焦虑在搜索行为（搜索情景、动机、频
率、搜索信息类型、搜索疾病类型、搜索平台）上存在显著性差异（p＜0.05）。④IU在健康焦虑与网络健康信息搜
索行为之间起中介作用。结论：①不同健康焦虑水平的搜索行为偏好不同，健康焦虑水平越高的用户，在线搜索
频率越高、持续时长越久。②健康焦虑与搜索行为存在因果关系，可作为预测搜索行为的因素。③健康焦虑通过
无法容忍不确定性对搜索行为产生影响，可通过缓解健康焦虑和对不确定性的容忍程度来优化搜索行为。
[Purpose/significance] To investigate the level and characteristics of online health information seeking be?
havior of people with health anxiety, and to explore the influence of health anxiety on online health information seeking
behavior.[Method/process] On January 30, 2021, solstice and February 22, 788 anonymous online questionnaires
were distributed to Changsha residents through convenience sampling, and 699 valid questionnaires were obtained by
collecting user information using somatic symptom severity scale (PHQ-15), OHIB scale, Intolerable Uncertain Scale
(IUS) and health anxiety scale (SHAI).The recovery rate was 88.7%.[Result/conclusion] In this study, ①The SHAI
points.②There was a positive correlation between OHIB score and total HA score, likelihood of disease and negative
outcome score (r=0.117-0.184, P<0.05).③Health anxiety inseeking behavior (search scenario, motivation, frequency,
search information types, disease types, platform) there are significant differences (P＜0.05). ④IU played a mediating
role between health anxiety and online health information seeking behavior.Conclusions: ①Different levels of health
anxiety have different search behavior preferences. The higher the level of health anxiety, the higher the frequency and
duration of online search. ②Health anxiety has a causal relationship with search behavior and can be used as a predic?
tor of search behavior. ③Health anxiety affects search behavior through the inability to tolerate uncertainty, and search
behavior can be optimized by alleviating health anxiety and the degree of uncertainty tolerance.
