It is widely accepted that suicidal behavior often occurs with little planning. We propose, however, that suicidal behavior is rarely if ever impulsive-that it is too frightening and physically distressing to engage in without forethought-and that suicidal behavior in impulsive individuals is accounted for by painful and fearsome behaviors capable of enhancing their capacity for suicide. We conducted a meta-analysis of the association between trait impulsivity and suicidal behavior and a critical review of research considering the impulsiveness of specific suicide attempts. Meta-analytic results suggest the relationship between trait impulsivity and suicidal behavior is small. Furthermore, studies examining a mediating role of painful and provocative behaviors have uniformly supported our model. Results from our review suggest that researchers have been unable to adequately measure impulsivity of attempts and that measures sensitive to episodic planning must be developed to further our understanding of this phenomenon.

重新考虑冲动与自杀行为之间的联系。

人们普遍认为，自杀行为往往很少有计划地发生。但是，我们建议，自杀行为很少是冲动的，它太可怕了，身体上令人痛苦，无法不加深思熟虑地从事其中；而冲动个体的自杀行为是由能够增强其自杀能力的痛苦和令人恐惧的行为造成的。 。我们对特质冲动与自杀行为之间的关联进行了荟萃分析，并对考虑到特定自杀企图的冲动性的研究进行了严格审查。荟萃分析结果表明，特质冲动与自杀行为之间的关系很小。此外，研究痛苦和挑衅行为的中介作用的研究一致支持了我们的模型。
