Exploring factors influencing the continued use intention of health science popularization WeChat accounts among university students in Chengdu.
Stratified cluster random sampling was employed to select students from 10 universities in Chengdu in 2023 as research subjects, with data collected via a questionnaire. The questionnaire encompassed demographic information, usage patterns of health science popularization WeChat accounts, and factors influencing continued use intentions. After designing the questionnaire on the Wenjuanxing website, teachers or tutors distributed the survey link or QR code to students, who voluntarily completed the questionnaire anonymously. Descriptive analysis was conducted using SPSS 26.0, while structural equation model fitting, path coefficient testing, and mediation effect testing were performed using AMOS 26.0.
After excluding invalid questionnaires, a total of 745 valid responses were included. The structural equation model demonstrated good fit(CMIN/DF=4.106, RMSEA=0.065, NFI=0.898, CFI=0.921). Path coefficient analysis revealed positive impacts of health information quality(standardized coefficient 0.54, P<0.001), social value(standardized coefficient 0.177, P<0.001), and perceived entertainment value(standardized coefficient 0.246, P<0.001) on expectation confirmation. Service quality negatively influenced perceived usefulness(standardized coefficient-0.223, P=0.037). Health information quality(standardized coefficient 0.899, P<0.001) and expectation confirmation(standardized coefficient 0.167, P=0.004) positively influenced perceived usefulness, which along with satisfaction(standardized coefficient 0.988, P<0.001) positively influenced continued use intention. The mediation effect analysis revealed that expectation confirmation indirectly affects continued use intentions through satisfaction, with an indirect effect of 0.475(95%CI 0.240-0.800). Health information quality indirectly influences continued use intentions through perceived usefulness and expectation confirmation, with indirect effects of 0.296(95%CI 0.094-0.768) and 0.290(0.085-0.897), respectively. Expectation confirmation also indirectly influences continued use intentions through perceived usefulness, with an indirect effect of 0.049(95%CI 0.004-0.140). Social value indirectly affects continued use intentions through expectation confirmation and perceived usefulness, with an indirect effect of 0.008(95%CI 0.000-0.040), and through expectation confirmation and satisfaction, with an indirect effect of 0.084(95%CI 0.015-0.233). The indirect effect of service quality on continued use intentions through perceived usefulness was-0.080(95%CI-0.138-0.016), which was not significant. Perceived entertainment value indirectly influences continued use intentions through expectation confirmation and perceived usefulness, with an indirect effect of 0.012(95%CI 0.000-0.052), and through expectation confirmation and satisfaction, with an indirect effect of 0.117(95%CI 0.030-0.298).
Expectation confirmation, health information quality, perceived entertainment value, perceived usefulness, and satisfaction are factors influencing users' continued usage intentions. Expectation confirmation, health information quality, and perceived entertainment value indirectly affect users' continued usage intentions through perceived usefulness and satisfaction.
探究影响成都大学生健康科普微信公众号持续使用意愿的因素。
采用分层整群随机抽样法，选取2023年成都10所高校的学生作为研究对象，通过问卷调查收集数据。问卷涵盖人口统计学信息、健康科普微信公众号的使用模式以及影响持续使用意愿的因素。在问卷星网站设计问卷后，由教师或辅导员将调查链接或二维码分发给学生，学生自愿匿名完成问卷。使用SPSS 26.0进行描述性分析，使用AMOS 26.0进行结构方程模型拟合、路径系数检验和中介效应检验。
排除无效问卷后，共纳入745份有效问卷。结构方程模型显示拟合良好（CMIN/DF = 4.106，RMSEA = 0.065，NFI = 0.898，CFI = 0.921）。路径系数分析表明，健康信息质量（标准化系数0.54，P<0.001）、社会价值（标准化系数0.177，P<0.001）和感知娱乐价值（标准化系数0.246，P<0.001）对期望确认有正向影响。服务质量对感知有用性有负向影响（标准化系数 -0.223，P = 0.037）。健康信息质量（标准化系数0.899，P<0.001）和期望确认（标准化系数0.167，P = 0.004）对感知有用性有正向影响，并与满意度（标准化系数0.988，P<0.001）一起对持续使用意愿有正向影响。中介效应分析表明，期望确认通过满意度间接影响持续使用意愿，间接效应为0.475（95%CI 0.240 - 0.800）。健康信息质量通过感知有用性和期望确认间接影响持续使用意愿，间接效应分别为0.296（95%CI 0.094 - 0.768）和0.290（0.085 - 0.897）。期望确认也通过感知有用性间接影响持续使用意愿，间接效应为0.049（95%CI 0.004 - 0.140）。社会价值通过期望确认和感知有用性间接影响持续使用意愿，间接效应为0.008（95%CI 0.000 - 0.040），并通过期望确认和满意度间接影响持续使用意愿，间接效应为0.084（95%CI 0.015 - 0.233）。服务质量通过感知有用性对持续使用意愿的间接效应为 -0.080（95%CI -0.138 - 0.016），不显著。感知娱乐价值通过期望确认和感知有用性间接影响持续使用意愿，间接效应为0.012（95%CI 0.000 - 0.052），并通过期望确认和满意度间接影响持续使用意愿，间接效应为0.117（95%CI 0.030 - 0.298）。
期望确认、健康信息质量、感知娱乐价值、感知有用性和满意度是影响用户持续使用意愿的因素。期望确认、健康信息质量和感知娱乐价值通过感知有用性和满意度间接影响用户的持续使用意愿。
