數位化技術的發展始於流程的電腦化，而隨著社群、行動、分析及雲端技術的湧現更使數位化產生不同的意義，透過社群媒體與行動技術的結合改變人們生活的模式，無論是企業組織、個人都能透過網際網路在虛擬環境中彼此交流，這種顛覆性的改變確實帶來極大的便利性，但同時也產生一些負面影響。透過行動社交網路與人交流、搜尋瀏覽時，部分用戶會因為承受科技壓力產生疲憊感，而傾向減少使用或是中斷使用社群媒體。
本研究由科技的陰暗面為切入點，輔以SSO理論框架來討論社群媒體所衍生之科技壓力對於用戶產生的負面反應、壓力源、以及後續影響等，冀望發展出一良好的理論模型探討資訊特性、科技特性、過載與社群網路疲勞之間的關聯性，更接續研究用戶是否在未來會減少使用。
本研究採用線上問卷方式發放予使用不特定之社群媒體的受測者，共計回收有效樣本數479份，分析結果指出某些感知過載類型，例如資訊過載、系統功能過載，確實會使用戶感到不同程度的精疲力竭，進而導致其減少使用的意圖，驗證了社群媒體科技壓力的負面效應。
然而，與過去文獻不同的是，本研究結果發現行動科技無所不在的連接性並不會對資訊過載及社群網路疲勞產生正面影響，且社交過載也不會對用戶的疲勞感有直接關連性，這可能是與時空背景以及環境、任務因素有關，除去職場上溝通、交付任務所形成的壓力，由於目前在日常生活中大多數人們以行動裝置及社群運算等科技相互聯繫已成必然，進而延伸用戶自主權及社群成癮的議題，使得過去認為行動社群網路工具中的無所不在連接性、社交過載會導致用戶疲勞的因果關係如今並不全然成立。

The digital technology develops from the computerization of workflows. With the emergence of social network, mobile computing, analysis technology and cloud computing, digitization has a different meaning. People's lifestyle has changed a lot through the combination of social media and mobile technology. Either organizations or individuals can communicate with others on networked virtual environments. This disruptive innovation has indeed brought great convenience but has also resulted in negative effect. While communicating with others and browsing the Web through mobile social network, partial users who feel exhausted when suffering from technostress tend to cut back on social media or discontinue using it.
With the dark side of technology, this research discusses the negative strain on users with the supplement of SSO theoretical framework, such as technostress from social media, stressors, the consequences, etc. The research is supposed to develop a theoretical model to explore the connections among characteristics of information, characteristics of technology, overload, and social network fatigue.
To conduct the survey, the online questionnaires were sent out to participants who use unspecified social media, and finally collected a valid simple size of 479. The analysis results indicate some types of perceived overload such as information overload and system feature overload make the users enthusiastic at various degrees, and consequently leads to a reduction in their intention of use time, and the negative effect of social medial-included technostress is verified.
Nevertheless, unlike past literature, the results of this study finds that the ubiquitous connectivity of mobile technology does not make a positive impact on information overload and social network fatigue, nor does social overload correlate directly with users’ fatigue. This might be related to different background, environment, and task factors. Except for pressure in the workplace caused by communication and task assignment, it is seemingly inevitable that most people in daily life contacts with each other through technology such as mobile devices and social network computing. With the issue of user autonomy and social network addiction, the causal relationship between ubiquitous connectivity, social overload in mobile social networking technology and user fatigue is not fully established today compared with the previous arguments.
