双路径视角下健康信息偶遇行为影响因素研究

A Study of Influencing Factors of Health Information Encountering Behavior from a Dual Path Perspective

探究健康信息偶遇行为影响因素与发生机理对健康信息学与信息偶遇研究都大有裨益。以精细加工可能性模型理论为基础,使用偏最小二乘结构方程建模方法对用户健康信息偶遇行为影响因素展开实证研究。同时使用调节效应简单斜率作图法和层次回归分析方法分别对健康信息素养的调节效应以及各潜变量间相互影响进行探索。结果表明:健康信息质量、健康信源可信性、健康信息新颖性、社交联接正向显著影响感知有用性,但社交联接对感知有用性的影响被其他三种因素弱化;环境便利性、情绪状态以及感知有用性显著正向影响健康信息偶遇行为,且环境便利性的影响作用被感知有用性削弱;健康信息素养正向显著调节健康信息质量、健康信源可信性、健康信息新颖性对感知有用性的影响;社会联接对感知有用性的影响受健康信息素养调节,健康信息素养高,则起促进作用,健康信息素养低,则起抑制作用。希望研究结果可为相关组织和个人提升对健康信息偶遇情况的合理利用提供理论参考。

Investigating the influencing factors and occurrence mechanisms of health information encountering behavior is beneficial to both health informatics and information encountering research.Based on elaboration likelihood model theory,this study empirically investigates the factors influencing users'health information encountering behavior by using partial least squares-structural equation model.At the same time,the moderating effect,simple slope mapping method and hierarchical regression analysis method were used to explore the moderating effect of health information literacy and the interaction between various latent variables.The study showed that health information quality,health source trustworthiness,health information novelty,and social connection positively and significantly influenced perceived usefulness,but the influence of social connection on perceived usefulness was weakened by the other three factors;environmental convenience,emotional state,and perceived usefulness significantly and positively influenced health information encountering behavior,and the influence of environmental convenience was weakened by perceived usefulness;health information literacy positively and significantly moderated the impact of health information quality,health source trustworthiness,and health information novelty on perceived usefulness;the influence of social connection on perceived usefulness was moderated by health information literacy,and high health information literacy played a promoting role,and low health information literacy played an inhibiting role.It is hoped that the results of this study can provide a theoretical reference for relevant organizations and individuals to improve the rational use of health information encountering.
