Personality disorder is associated with increased risk of suicidal behavior. The authors aimed to investigate the association between number of personality disorder traits and suicidality risk following sudden bereavement. A secondary analysis of cross-sectional data on 3,167 young adults in the United Kingdom who had experienced sudden bereavement investigated the association between number of traits (measured using a standardized screening instrument) and postbereavement suicide attempt and suicidal ideation. Using multivariable logistic regression, the authors found a linear relationship between number of traits and suicide attempt (adjusted odds ratio [AOR] = 1.36, 95% CI [1.23, 1.49]) and suicidal ideation (AOR = 1.31, 95% CI [1.25, 1.38]) following bereavement. This represented an increase in odds by 36% and 31%, respectively, for each additional personality trait. The authors suggest that individuals with a greater number of traits suggestive of a personality disorder diagnosis are at increased risk of suicidality after a negative life event.

突然丧亲后人格障碍特征与自杀之间的关联：一项全国性横断面调查。

人格障碍与自杀行为风险增加有关。作者旨在调查突然丧亲后人格障碍特征的数量与自杀风险之间的关联。对英国 3,167 名经历过突然丧亲的年轻人的横断面数据进行二次分析，调查了特征数量（使用标准化筛选工具测量）与丧亲后自杀企图和自杀意念之间的关联。使用多变量逻辑回归，作者发现性状数量与自杀企图（调整优势比 [AOR] = 1.36, 95% CI [1.23, 1.49]）和自杀意念（AOR = 1.31, 95% CI [1.25]）之间存在线性关系, 1.38]) 丧亲后。这意味着赔率分别增加了 36% 和 31%，对于每个额外的人格特征。作者认为，具有更多暗示人格障碍诊断特征的个体在经历负面生活事件后自杀的风险增加。
