基于C-A-C理论的健康科普视频对用户持续使用意愿的影响研究

Impact of Health Science Video on Users'Intention to Continue Usage:An Investigation from the Perspective of the C-A-C Theory

目的为了提高用户对健康科普视频的持续使用意愿,使设计人员准确掌握健康科普视频的用户需求,优化健康科普视频设计与开发。方法基于C-A-C理论,构建健康科普视频、情绪唤醒和用户持续使用意愿的理论模型,应用结构方程模型论证健康科普视频中博主形象气质、专业性、信息质量、互动质量因素与用户情绪唤醒和持续使用意愿的路径关系。结果健康科普视频中博主形象气质、专业性、信息质量、互动质量对用户情绪唤醒和持续使用意愿具有正向影响作用。结论健康科普视频博主形象气质、专业性、信息质量、互动质量作为影响用户情绪和持续使用意愿的关键因素,能够帮助设计人员从用户视角提高用户情绪唤醒和持续使用意愿,为健康科普视频的设计和创新提供理论和实践参考。

The work aims to optimize the design and development of health science videos to enhance users'sustained intention to continue using health science videos and enable designers to accurately grasp users'needs.Based on the C-A-C theory,a theoretical model was constructed to establish the relationship between health science videos,user emotional arousal,and users'intention to continue usage.Structural equation modeling was employed to validate the path relationships among blogger image,expertise,information quality,interaction quality within health science videos,user emotional arousal,and users'intention to continue usage.The findings indicated that blogger image,expertise,information quality,and interaction quality within health science videos had a positive impact on users'emotional arousal and intention to continue usage.Blogger image,expertise,information quality,and interaction quality in health science videos are identified as key factors influencing users'emotional and sustained intention to continue usage.These findings provide valuable insights for designers to improve user emotional arousal and intention to continue usage from a user-centered perspective,and offer theoretical and practical references for the design and innovation of health science video.
