摘要
微信已成为用户获取信息的主要渠道,其中健康类信息又是微信平台中最容易引发用户分享行为的重要内容之一,但当前关于健康信息分享行为及其影响因素的研究仍然有限。因此本文在计划行为理论基础上,结合技术接受模型与社会认知理论建立研究假设,将影响因素分为态度、价值、环境三个层面,包含感知有用、信息质量、自我效能、感知收益、社会支持和群聚效应等六个具体指标。采用在线调查问卷收集数据(N=375),并构建结构方程模型对模型进行检验。研究发现,以上变量均与微信用户健康信息分享意愿呈正相关。其中,价值因素的总效应最高;而个体对信息的态度及环境对个体的影响也是重要因素,但相关程度递减。同时,用户的年龄和自感健康状况也会影响健康信息分享行为。本研究提出了一个新的理论整合模型来解释微信用户健康信息分享行为的影响因素,这也为未来利用社交媒体进行信息分享,从而激励公众参与健康传播提供重要的理论与实践启示。
We Chat has become the main social media platform for users to obtain information.Health information is one of the most important contents which can easily trigger users’sharing behavior on the WeChat platform.Yet,knowledge about in?uence factors of health information sharing behavior in social media remains limited.Therefore,to discuss the impact factors of users’health information sharing behavior,this paper established research hypotheses based on the theory of planned behavior,technology acceptance model,and social cognitive theory.The impact factors are divided into attitude,value,and environment,which include six variables:perceived usefulness,information quality,self-ef?cacy,perceived bene?ts,social support,and critical mass.To examine the research model,an online questionnaire was drawn up and administered to 375WeChat users.The results of structural equation modeling analysis revealed that the research model fits the data well.The study found that all variables were positively correlated with We Chat users’health information sharing intention.Among them,the value factor has the greatest effect.And the individual’s attitude towards information and the in?uence of environment on the individual are also important factors,but the degree of effect decreases.Meanwhile,users’age and self-perceived health status also affect their health information sharing behavior.Overall,this study presents a new integrated conceptual model to explain in?uence factors that affect WeChat users’sharing behavior regards to health information,and provides theoretical and practical implications regarding motivating public participation through information sharing on social media in health communication.
