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，影响大约3-4%的普通人群（Krzanowska和Kuleta，2017）。在《精神障碍诊断与统计手册V》（美国精神病学协会，2013年）中，它被归类为强迫性相关障碍，其特征是“不必要的强迫性思想”或“侵入性思想”，以及减轻患者焦虑的重复强迫行为。Hunt和Brookes（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与精神疾病患者使用的在线论坛进行三角化，以更好地了解他们的生活经历。事实上，Friedrich（2015：99）认为，强迫症在很大程度上被社会误解，批评性话语分析的框架，结合分析计算机介导的交流，如在线论坛，可以帮助澄清关于强迫症的常见误解。之前已经通过半结构化访谈（克纳普顿，2018）和强迫症亚型的话语分析（Coimbra-Gomes，2020）进行了关于强迫症语言结构的研究。我建议的研究是第一次调查到现有的论坛话语的强迫症，这将有利于更广泛地了解这种疾病是如何经历和建设的患者。

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.
