The study attempted to identify characteristics that differentiate multiple suicide attempters from single attempters in individuals with personality disorders (PDs) and/or major depression.
Participants were 431 participants enrolled in the Collaborative Longitudinal Study of Personality Disorders from July 1996 to June 2008. Suicide attempts were assessed with the Longitudinal Interval Follow-up Evaluation at 6 and 12months, then yearly through 10years. Logistic regression was used to compare single attempters to multiple attempters on Axis I and II psychiatric disorders and personality trait variables.
Twenty-one percent of participants attempted suicide during the 10years of observation, with 39 (9.0%) reporting a single suicide attempt and 54 (12.5%) reporting multiple suicide attempts. Although no significant differences in were found in baseline Axis I disorders, multiple attempters were significantly more likely to meet criteria for borderline personality disorder and to have higher impulsivity scores than single attempters.
These results underscore the importance of considering both personality disorders and traits in the assessment of suicidality.
本研究试图确定人格障碍（PD）和/或重度抑郁症患者中，多次自杀未遂者与单次自杀未遂者之间的区别特征。
参与者为 1996 年 7 月至 2008 年 6 月期间参加人格障碍合作纵向研究的 431 名参与者。使用纵向间隔随访评估在 6 个月和 12 个月、随后每年直至 10 年评估自杀未遂。采用逻辑回归比较单未遂组和多未遂组在轴 I 和 II 精神障碍和人格特质变量方面的差异。
在 10 年的观察期间，21%的参与者尝试过自杀，其中 39 人（9.0%）报告了单次自杀未遂，54 人（12.5%）报告了多次自杀未遂。尽管在基线轴 I 障碍方面未发现显著差异，但多次自杀未遂者更有可能符合边缘型人格障碍的标准，且冲动性评分高于单次自杀未遂者。
这些结果强调了在评估自杀倾向时，同时考虑人格障碍和特质的重要性。
