Impulsivity in suicidal behavior can describe the attempt (state) or the attempter (trait). There are no studies simultaneously measuring attempt impulsivity and attempter impulsivity in representative samples of suicide attempts. A one-year study of 278 suicide attempts in a general hospital tested the continuous versus dichotomous relationship between attempter impulsivity (Barratt Impulsiveness Scale) and attempt impulsivity (low scores in the planning subscale of Beck's Suicidal Intent Scale). Attempter impulsivity was not a good predictor of attempt impulsivity independently of how both dimensions were measured (continuous or dichotomous ways). Impulsive attempts were associated with low lethality and lack of depression. Opportunities for prevention of suicide attempts in major depression and some personality traits may exist but require attentive monitoring of suicidal ideation and intent.
自杀行为中的冲动性可以描述自杀未遂（状态）或自杀未遂者（特质）。目前尚无研究在具有代表性的自杀未遂样本中同时测量未遂冲动性和未遂者冲动性。一项针对综合医院278例自杀未遂案例进行的为期一年的研究，检验了未遂者冲动性（巴雷特冲动性量表）与未遂冲动性（贝克自杀意念量表计划子量表得分低）之间的连续与二分关系。无论这两个维度是如何测量的（连续或二分方式），未遂者冲动性都不是未遂冲动性的良好预测指标。冲动性的自杀未遂与低致死率和无抑郁症状相关。在重度抑郁症和某些人格特质中，可能存在预防自杀未遂的机会，但需要密切监测自杀意念和意图。
