摘　　要：以信息寻求综合模型为基础,结合社会认知理论,构建囊括个人因素(显著性、自我效能感)、载体因素(信息载体特征、信息载体效用)、环境因素(社会影响、信息过载)的综合研究框架,系统性探究中老年用户在微信和抖音两个典型社交媒体平台上健康信息搜寻行为的影响因素。采用问卷调查法和结构方程模型进行实证分析,结果显示在微信和抖音平台中自我效能感、载体因素均正向影响中老年用户健康信息搜寻行为,社会影响仅在微信平台、信息过载仅在抖音平台直接影响健康信息搜寻行为。经中介效应分析,自我效能感、信息载体特征、社会影响通过信息载体效用间接影响健康信息搜寻行为,信息过载仅在微信平台中具有间接作用。本文旨在拓宽社交媒体健康信息搜寻行为的研究语境,并为积极老龄化及社交媒体平台发展提供针对性策略建议。Based on the comprehensive model of information seeking,combined with social cognitive theory,we construct a comprehensive research framework encompassing personal factors(salience,self-efficacy),carrier factors(information carrier characteristics,information carrier utility),and environmental factors(social influence,information overload),aiming to systematically explore the influencing factors of health information seeking behavior of middle-aged and elderly users on two typical social media platforms,WeChat and TikTok.The empirical analysis conducted using questionnaire survey and structural equation model reveals that self-efficacy and carrier factors all positively affect health information seeking behavior of middle-aged and elderly users in WeChat and TikTok.Social influence directly affects health information seeking behavior only in WeChat platform,whereas information overload only has direct impact in TikTok platform.Through mediating effect analysis,we find that self-efficacy,information carrier characteristics,and social influence indirectly affect health information seeking behavior via information carrier utility,and information overload only has an indirect effect in WeChat platform.This article aims to widen the research context of health information seeking behavior in social media,and provide targeted strategic recommendations for active aging and the development of social media platforms.
