The current study explored whether camouflaging autistic traits is associated with defeat and entrapment and lifetime suicidal thoughts, as predicted by the Integrated Volitional Model of Suicide (IMV model).
180 UK undergraduate students (76.7% female 18-67 years) completed a cross-sectional online survey from February 5 to March 23, 2020, including self-report measures of defeat and entrapment (SDES), autistic traits (AQ-10), depression (PHQ-9), anxiety (GAD-7), camouflaging autistic traits (CAT-Q), and lifetime suicidal thoughts and behaviors (SBQ-R item 1).
After controlling for age, gender, current depression, and anxiety symptoms, autistic traits accounted for significantly more of the variance in defeat and entrapment (1.1%), and camouflaging accounted for a further 3.2% of the variance. The association between autistic traits and lifetime suicidality was significantly mediated by camouflaging, defeat, and entrapment. After controlling for age, gender, current depression, and anxiety symptoms, defeat and entrapment (but not camouflaging) accounted for significantly more variance in lifetime suicidal thoughts. The interaction between camouflaging, defeat and entrapment predicted significantly less variance in lifetime suicidal thoughts than either variable alone.
Results suggest that camouflaging autistic traits is a transdiagnostic risk factor for lifetime suicidality, relevant to the defeat and entrapment constructs of the IMV model.
本研究通过综合意志模型（IMV 模型），探讨了伪装自闭症特征是否与失败感和束缚感以及终生自杀意念有关。
2020 年 2 月 5 日至 3 月 23 日，180 名英国本科生（76.7%为女性，年龄 18-67 岁）完成了一项横断面在线调查，包括失败感和束缚感量表（SDES）、自闭症特质问卷（AQ-10）、抑郁（PHQ-9）、焦虑（GAD-7）、伪装自闭症特质问卷（CAT-Q）和终生自杀意念和行为（SBQ-R 项目 1）的自我报告测量。
在控制年龄、性别、当前抑郁和焦虑症状后，自闭症特征解释了更多的失败感和束缚感（1.1%）的差异，伪装则进一步解释了 3.2%的差异。自闭症特征与终生自杀意念的关联，由伪装、失败感和束缚感显著中介。在控制年龄、性别、当前抑郁和焦虑症状后，失败感和束缚感（但不是伪装）解释了更多的终生自杀意念的差异。伪装、失败感和束缚感的交互作用预测终生自杀意念的差异明显少于任何一个变量单独预测的差异。
结果表明，伪装自闭症特征是终生自杀意念的一种跨诊断风险因素，与 IMV 模型的失败感和束缚感结构相关。
