Mad Linguistics: A corpus-based and service-user informed critical discourse analysis of online Obsessive-Compulsive Disorder fora.

强迫症（OCD）是一种精神疾病，影响了大约3-4%的普通人群（Krzanowska和Kuleta， 2017）。在《精神疾病诊断与统计手册V》（美国精神病学协会，2013年）中，它被归类为一种强迫相关疾病，其特征是“不想要的强迫思想”或“侵入性思想”，以及缓解患者焦虑的重复性强迫行为。亨特和布鲁克斯（2020）的研究提出了一个令人信服的案例，将语料库语言学和话语分析三角化到精神疾病患者使用的在线论坛上，以更好地了解他们的生活经历。事实上，Friedrich（2015:99）认为强迫症在社会上很大程度上是被误解的，批判性话语分析的框架，结合分析计算机媒介的交流，如在线论坛，可以帮助阐明关于强迫症的常见误解。之前已经通过半结构化访谈（Knapton, 2018）和强迫症亚型的话语分析（Coimbra-Gomes, 2020）对强迫症的语言结构进行了研究。我提出的研究是对现有的关于强迫症的论坛讨论的第一次探索，这将有助于更广泛地了解患者是如何经历和构建这种疾病的。

Obsessive-Compulsive Disorder (OCD) is a mental illness that affects approximately 3-4% ofthe general population (Krzanowska and Kuleta, 2017). In the Diagnostic and StatisticalManual for Mental Disorders V (American Psychiatric Association, 2013), it is classified as acompulsive-related disorder characterised by 'unwanted obsessive thoughts', or 'intrusivethoughts', and repetitive compulsions that alleviate the anxiety felt by sufferers. Research byHunt and Brookes (2020) makes a compelling case for triangulating corpus linguistics anddiscourse analysis to online fora used by sufferers of mental illnesses to better understandtheir lived experiences. Indeed, Friedrich (2015:99) argues OCD is largely misunderstood insociety and that a framework of critical discourse analysis, combined with analysingcomputer-mediated communication such as online fora, can help to elucidate commonmisconceptions about OCD. There have been previous research around linguisticconstructions of OCD through semi-structured interviews (Knapton, 2018) and discursiveanalyses of OCD subtypes (Coimbra-Gomes, 2020). My proposed research is the firstenquiry into existing fora discourses of OCD that will benefit a wider understanding of howthis illness is experienced and constructed by sufferers.
