Suicidal ideation is prevalent in patients with obsessive–compulsive disorder (OCD); but, during COVID-19, it may be increased. The present study aimed to examine the effects of obsessive–compulsive (OC) symptom dimensions and OCD severity on suicidal ideation by considering the role of stress responses in reaction to COVID-19 in a clinical sample of patients with OCD. In a cross-sectional study, 304 patients with OCD completed measures of OC symptom dimensions, OCD severity, general mental health (depression and anxiety), and COVID-19-related stress. Results showed that after controlling for depression, anxiety, comorbidity, and lifetime suicide attempts, the OC symptom dimensions of responsibility for harm and unacceptable obsessional thoughts as well as general severity had indirect effects on suicidal ideation through the specific stress responses to COVID-19, including traumatic stress and compulsive checking. The study shows that OCD patients with specific OC symptom dimensions and severe OCD are more likely to have suicidal ideation during the pandemic. Further, the specific stress responses to COVID-19 may be an underlying mechanism. Clinicians should carefully assess suicidal ideation in patients with OCD who experience responsibility for harm and unacceptable thoughts, particularly during the pandemic.

强迫症患者的强迫症状维度和一般严重程度与自杀意念的关联：对 COVID-19 的特定应激反应的作用


自杀意念在强迫症 (OCD) 患者中普遍存在；但在新冠肺炎 (COVID-19) 期间，这一数字可能会增加。本研究旨在通过考虑强迫反应在强迫症患者临床样本中对 COVID-19 的反应中的作用，探讨强迫症 (OC) 症状维度和强迫症严重程度对自杀意念的影响。在一项横断面研究中，304 名强迫症患者完成了强迫症症状维度、强迫症严重程度、一般心理健康状况（抑郁和焦虑）以及 COVID-19 相关压力的测量。结果显示，在控制抑郁、焦虑、合并症和终生自杀企图后，OC 症状维度（伤害责任和不可接受的强迫性想法）以及一般严重程度通过对 COVID-19 的特定压力反应对自杀意念产生间接影响。包括创伤性应激和强迫性检查。研究表明，具有特定 OC 症状维度和严重强迫症的强迫症患者在大流行期间更有可能产生自杀意念。此外，对 COVID-19 的特定应激反应可能是一个潜在机制。临床医生应仔细评估强迫症患者的自杀意念，因为他们对伤害负有责任并有不可接受的想法，特别是在大流行期间。
