摘要
[目的/意义]后疫情时代短视频成为公众获取健康信息的重要渠道之一,探究短视频平台用户健康信息采纳的前因变量及其复杂影响,系统优化移动短视频用户健康信息采纳体验,促进用户健康信息采纳行为的持续性。[方法/过程]以信息采纳理论和HSM模型为基础,构建健康类短视频信息采纳研究框架,采用结构方程模型方法分析用户健康信息采纳行为前因变量的作用路径,采用QCA方法探索影响前因条件对短视频用户健康信息采纳的组合效应。[结果/结论]SEM分析结果表明,内容质量、平台声誉、信源可信度显著影响信息有用性,进而影响短视频用户的采纳意愿,内容质量和信息有用性在表达质量对用户采纳意愿的影响中起到链式中介作用;fsQCA分析结果表明,短视频用户的健康信息采纳决策受系统式线索和启发式线索共同影响,呈现两种类型:系统式线索主导式和启发式线索主导式,表达质量在这两种类型中均存在;触发短视频用户的不采纳决策有3项条件构型,低内容质量和低感知信息有用性均为触发不采纳的核心条件。
[Purpose/Significance]Mobile short video apps like Tiktok have become one of the most frequently used tools to obtain/exchange health information in post-epidemic era.This study analyzed the complex relationships between the antecedents and users'health information adoption in mobile short video apps in terms of necessary and sufficient conditions,in order to optimize users'experience with health information adoption systematically,which in turn generates users'sustainability.[Method/Process]Based on both the information adoption model(IAM)and the heuristic-systematic model(HSM),this study constructed a health information adoption model of mobile short videos,in which five predictor variables(content quality,expression quality,information source credibility,app's reputation,perceived information usefulness)and an outcome variable(health information adoption)were included.The construct validity,reliability and symmetrical relationships between the five predictor variables and an outcome condition were examined using structural equation model(SEM)method.Fuzzy-set qualitative comparative analysis(fsQCA)was used to examine and reveal the configuration models.[Results/Conclusions]The results from PLS-SEM method and fsQCA validated the IAM and HSM in the context of mobile short video apps.Specifically,the results from PLS-SEM show that systematic and heuristic clues jointly affect users'adoption of health information.Content quality,app's reputation and information resource credibility significantly impact perceived information usefulness,and further affect the health information adoption.Expression quality has a significant effect on content quality,but no obvious effects on perceived information usefulness and health information adoption.The results of fsQCA reveal three configurations to affect users'health information adoption(i.e.,content quality*expression quality*perceived information usefulness*information resource credibility),and another three configurations to affect users'non-adoption i.e.,~content quality*
