Despite the focus on impulsivity within suicide research, it remains unclear the extent to which impulsivity assessments, that purportedly tap similar constructs, show significant overlap in samples of individuals with suicidal behaviors. In a sample of 69 suicide attempters, we took a multitrait, multimethod approach to examine the relation among various questionnaire and behavioral assessments of impulsivity facets. With the exception of urgency and go-stop performance, there was little evidence of concordance between questionnaire and behavioral measures. These findings suggest researchers cannot presume that measures of "impulsivity" assess similar psychological processes and that more nuanced terminology is needed.
尽管自杀研究的重点是冲动，但仍不清楚冲动评估在多大程度上与自杀行为个体样本中的类似结构具有显著重叠，这些评估据称是在测量类似的结构。在 69 名自杀未遂者的样本中，我们采用多特质、多方法的方法来检查各种问卷和冲动方面的行为评估之间的关系。除了紧迫性和停止表现外，问卷和行为测量之间几乎没有一致性的证据。这些发现表明，研究人员不能假设“冲动”的测量方法评估类似的心理过程，需要更细致的术语。
