社群媒體已與現代人的生活密不可分，並成為人們主要的資訊來源，社群媒體的使用者長期持續關注來自社群網路的大量資訊，這些持續增加的資訊可能會導致社群網路疲勞，從而導致身心壓力。

本研究蒐集將社群媒體作為資訊來源情境下的資訊品質構面，以Stressor-strain-outcome(SSO)框架，探討了資訊品質如何透過資訊過載、資訊焦慮影響社群網路疲勞，並了解其中是否具有中介效果。

本研究基於線上問卷向Facebook使用者收集了340份有效問卷，實證結果表示Facebook的使用者個人認為社群上的資訊品質應具備適當的資訊量、資訊相關性、資訊完整性、資訊即時性及資訊客觀性之特徵，而資訊焦慮對於資訊品質與社群網路疲勞的關係具有中介影響的效果，當使用者感到社群網路疲勞時，也會進而造成各種不持續使用行為，如:資訊忽略、短暫休息、控制活動及暫停使用。

最後，本研究以資訊品質角度提供社群媒體使用者、行銷人員及社群媒體管理者一些關於如何管理及避免引起疲勞的因素之建議，以促進使用者持續使用。

In recent years, social media has involved in our lives and acted as a major source of information. Social media users continue to consume a large amount of information from social networks for a long time. Some researchers have found it could increase the probability of social networks fatigue, which would lead to long-term effects on physical or mental health.

This study investigates information quality aspects in the context of using social media as an information source and adopts the Stressor-strain-outcome (SSO) framework to explore how information quality affects social network fatigue through information overload and information anxiety to understand whether they have mediating effects.

The proposed research model was empirically validated via 340 valid online questionnaires collected from Facebook users. The results indicated five dimensions of information quality on Facebook and found information anxiety has a mediating effect on the relationship between information quality and social network fatigue. When users suffer from social network fatigue, it will also cause various discontinuous usage, such as information avoidance, short breaks, control activities and suspension intension.

The findings provide some suggestions from the perspective of information quality to social media users, marketing specialists, and social media managers so as to manage and avoid factors that cause fatigue and remain active users.
