Disentangling user fatigue in WeChat use: the configurational interplay of fear of missing out and overload
研究通过问卷调查363名中国社交网站用户，采用模糊集定性比较分析，发现错失恐惧与多种过载（社交、沟通、信息、系统功能）的特定组合会导致用户疲劳，其中错失恐惧、信息过载和系统功能过载是关键条件。
Purpose The purpose of this study is to examine how the interplay of stressor (e.g. fear of missing out, FoMO) and strains (e.g. perceived social overload, communication overload, information overload and system feature overload) in social networking sites (SNS) use can contribute to users’ SNS fatigue from a configurational view. Design/methodology/approach Data were collected among 363 SNS users in China via an online survey, and fuzzy-set qualitative comparative analysis (fsQCA) was applied in this study to scrutinize the different combinations of FoMO and overload that contribute to the same outcome of SNS fatigue. Findings Six combinations of casual conditions were identified to underlie SNS fatigue. The results showed that FoMO, perceived information overload and system feature overload are the core conditions that contribute to SNS fatigue when combined with other types of overloads. Originality/value The current work supplements the research findings on SNS fatigue by identifying the configurations contributing to SNS fatigue from the joint effects of stressor (FoMO) and strain (perceived social overload, communication overload, information overload and system feature overload) and by providing explanations for SNS fatigue from the configurational perspective.
