Previous studies have demonstrated individual associations between borderline personality disorder (BPD), panic attacks (PAs), and panic disorder (PD) in relation to suicide attempts (SAs). This study examined the comorbid effects of these variables. Data from wave 2 of the National Epidemiologic Survey of Alcohol and Related Conditions (N = 34,653) were used to examine using logistic regression the relationship between individuals with BPD (n = 562), PA (n = 253), PD (n = 255), comorbid BPD and PD (n = 146), and co-occurring BPD and PA (n = 119) who had attempted suicide. It was found that BPD, PD, and PA are associated with SAs. Comorbid PD and BPD, or PA and BPD, only slightly increased the association of BPD alone with SA. Associations were greatly decreased after controlling for affective dysregulation. These findings emphasize the importance of affective dysregulation in individuals with BPD in relation to suicide attempts.
既往研究已证实边缘型人格障碍（BPD）、惊恐发作（PA）和惊恐障碍（PD）与自杀未遂（SA）之间存在个体关联。本研究考察了这些变量的共病效应。利用全国酒精及相关疾病流行病学调查第二轮的数据（N = 34,653），采用逻辑回归分析，研究了患有BPD（n = 562）、PA（n = 253）、PD（n = 255）、共病BPD和PD（n = 146）以及同时存在BPD和PA（n = 119）的自杀未遂个体之间的关系。研究发现，BPD、PD和PA均与SA相关。共病PD和BPD或PA和BPD，仅略微增加了单独BPD与SA的关联。在控制情感失调后，关联度大幅降低。这些发现强调了情感失调在BPD个体自杀未遂中的重要性。
