【摘要】：以新浪微博、腾讯微博等为主的微博客已经成为用户获取健康信息的主要平台。探索微博环境下用户健康信息扩散行为影响因素是干预"伪健康"信息扩散的必须手段,也是科学、准确的健康信息扩散最大化的决策依据。以已有相关研究为理论基础,构建微博环境下用户健康信息扩散行为的影响因素模型。运用问卷调查法,借助SPSS22.0和Amos21.0进行实证研究。首先运用SPSS22.0进行探索性因子分析筛选测量题项以及进行问卷信度效度的初测。然后,运用Amos21.0进行验证性因子分析,构建模型,并进行模型的拟合修正、信度效度验证。最后,进行测量变量的显著性检验。得出结论,微博用户健康信息扩散行为模型的拟合效果良好,各项指标均在合理范围内。显著性检验发现微博用户健康信息扩散意愿受到健康信息的外显特征、感知信息质量、用户关系强度的正向影响(P0.05),用户扩散意愿显著正向影响扩散行为(P0.01),主题相关性对健康信息扩散意愿不存在显著性影响(P0.05)。
[Abstract]:Weibo visitors, who mainly include Sina Weibo, Tencent Weibo and others, have become the main platform for users to obtain health information. Exploring the influencing factors of users' health information diffusion behavior is a necessary means to interfere with the spread of "pseudo health" information. It is also a scientific and accurate decision-making basis for maximizing the diffusion of health information. Based on the existing relevant research, this paper constructs a model of influencing factors of users' health information diffusion behavior under the environment of Weibo. With the help of SPSS22.0 and Amos21.0, the empirical research is carried out. Firstly, the exploratory factor analysis is used to screen the items and the reliability and validity of the questionnaire are tested by SPSS22.0. Then, the model is constructed by using Amos21.0 to carry out confirmatory factor analysis. Finally, the significance of measuring variables is tested. It is concluded that the fitting effect of Weibo user health information diffusion behavior model is good. The significant test found that Weibo user's health information diffusion will be influenced by the explicit characteristics of health information and perceived information quality. The positive influence of user relationship strength was P0.05. the user's diffusion intention significantly positively affected the diffusion behavior P0.01. there was no significant effect of thematic correlation on health information diffusion willingness.
