Individuals with bulimia nervosa often experience suicidal ideation. Identity disturbance, or unstable sense of self, has been connected both to eating disorders and to suicidality. This study sought to test whether identity problems were related to severity of current suicidal ideation in a sample of women with bulimic-spectrum pathology, above and beyond history of suicidal behavior and several symptoms of borderline personality disorder. Women ( = 204; 90.7% Caucasian; = 25.7 years [ = 8.8]) with bulimic-spectrum pathology completed self-report personality assessments and items evaluating suicidality. A hierarchical linear regression was utilized to examine the association between identity problems and severity of current suicidal ideation, before and after inclusion of relevant clinical features (i.e., suicide attempt history [Step 2], affective lability, stimulus seeking, and rejection [Step 3]). Identity problems were directly associated with severity of current suicidal ideation (β = .481, < .001). This relationship retained significance after inclusion of suicide attempt history (β = .335, < .001) as well as borderline personality disorder symptoms (β = .324, < .001). Identity problems displayed a robust relationship with suicidal ideation severity in women with bulimic-spectrum pathology. Findings suggest that identity problems may be a specifically relevant personality feature regarding presence and severity of suicidal ideation in this high-risk group, even after considering the contributions of history of suicidal behavior and various symptoms of borderline personality disorder. There may be value in attending to identity problems when considering suicidal ideation in this population. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
神经性贪食症患者常常有自杀念头。身份认同障碍，即不稳定的自我意识，与饮食失调及自杀倾向均有关联。本研究旨在检验在患有贪食症谱系病理的女性样本中，身份认同问题是否与当前自杀念头的严重程度相关，这一关联独立于自杀行为史及边缘型人格障碍的若干症状。患有贪食症谱系病理的女性（ = 204；90.7%为白种人； = 25.7岁[ = 8.8]）完成了自我报告式人格评估及自杀倾向评估项目。采用分层线性回归分析，在纳入相关临床特征（即自杀未遂史[第2步]、情感易变性、寻求刺激和被拒斥感[第3步]）前后，检验身份认同问题与当前自杀念头严重程度之间的关联。身份认同问题与当前自杀念头的严重程度直接相关（β = .481， < .001）。在纳入自杀未遂史（β = .335， < .001）以及边缘型人格障碍症状（β = .324， < .001）后，这种关系依然显著。在患有贪食症谱系病理的女性中，身份认同问题与自杀念头严重程度呈现出强烈关联。研究结果表明，即使考虑到自杀行为史及边缘型人格障碍的各种症状的影响，身份认同问题可能仍是这一高危群体中与自杀念头的存在及严重程度特别相关的人格特征。在考虑这一人群的自杀念头时，关注身份认同问题可能具有重要意义。（PsycInfo数据库记录 (c) 2022美国心理学会，保留所有权利）
