近年來網路社群成為人們討論精神疾患的重要平台，卻也可能存在更幽微複雜的歧視型態。2021 年，擁有兩百萬以上訂閱戶的台灣 YouTuber 阿滴在頻道上發布自述憂鬱症的影片，說明憂鬱症成因如何複雜地交纏，然而 Dcard 論壇上的網民討論此事時仍傾向理解為線性歸因，並追究阿滴的個人責任。本研究以 van Dijk 的社會認知取徑（Sociocognitive Approach, SCA）闡釋網民以何種言說策略將阿滴及憂鬱症患者定義為他者，建構出一種不負責任的、造成社會負擔的憂鬱症患者形象。

 In recent years, social media have become an important platform for people to discuss mental illnesses. However, it is also possible that more complex and subtle forms of discrimination may exist on social media. In 2021, RD（阿滴）, a Taiwanese YouTuber whose channel has over 2 million subscribers, confessed that he was officially diagnosed with depression. He explained the causes of his health issue in his YouTube video, and how complex these interweaving reasons are. However, netizens on Dcard, the popular forum among Taiwanese college students, tended to view it as a linear attribution and claimed that RD should be accountable for his own disease. With the Sociocognitive Approach (SCA), this study illustrates the discourse strategies used by netizens to define RD and depression patients as Other, and to construct an irresponsible figure which is a burden to society.
