社群媒體使用模式研究：從自尊與自我揭露出發探討社群媒體對使用者心理健康的影響

本研究以使用者自尊與自我揭露作為使用動機，探討這兩個方面與使用社群媒體的關係，並探討使用社群媒體對心理健康的影響。本研究針對社群媒體Facebook使用者進行線上問卷調查，共蒐集到589個有效樣本。問卷資料採用 SPSS 25及 SmartPLS 3.0 統計軟體進行統計資料分析。研究結果發現自尊對網絡自我揭露的功能是有顯著的正向影響關係，而使用者自尊高低對於社群媒體使用是有顯著的負向影響關係。另外，除了「隱私」功能外，其他網絡自我揭露功能對社群媒體使用是沒有顯著影響。而社群媒體使用對使用者心理健康沒有顯著影響。社群媒體使用模式是本研究的另一個研究重點，本研究將台灣的Facebook使用者劃分為五種社群媒體使用模式，關係維持者、低使用者、思想抒發者、生活分享者和社交花蝴蝶。本研究發現不同的社群媒體使用模式會有各自的社群媒體使用策略，但所有類型的社群媒體使用者都會作出關係維護等低使用的行為，或多或少參與到社群媒體當中。而五種社群媒體使用類型中，思想抒發者的心理健康最為良好，生活分享者和社交花蝴蝶這發文頻率較高的使用類型心理健康相對較差，可見不同的發文內容和頻率是會影響到使用者心理健康。

This study explored the relationship between the two aspects: self-esteem and self-disclosure and the usage of social media, followed by investigating the impact of using social media on mental health. In this study, a sample consisted of 589 respondents, who were Facebook users, was obtained from an online survey in Taiwan. The Statistical Product and Service Solutions (SPSS 25) and the partial least squares (PLS 3.0) method were employed to test the conceptual model and hypotheses. The results showed that the self-esteem of social media users had a significant positive influence on the functions of online self-disclosure, and self-esteem also had a significant Negative influence on the usage of social media. Besides, it was found that except for "privacy" function, the other self-disclosure functions had no significant effect on the usage of social media. Moreover, the usage of social media had no significant influence on users’ mental health. The usage modes of social media was another focus of this study. With a sample from Taiwan Facebook users, five social media usage modes, maintainers, low frequency users, expressers, life sharers, and social butterflies. This study showed that although different social media usage modes had their corresponding using patterns, all of them would make low-use behaviors such as relationship maintenance. Among the five social media usage modes, the most positive mental health was found in expressers, whereas mental health was relatively worse in life sharers and social butterflies. Thus, it revealed that the content of posts would affect the mental health of users.
