冲动增强被认为有助于从自杀念头到自杀行为的转变，因此，冲动应该区分那些有过自杀企图的人和那些只考虑过自杀的人(仅限于意想者)这一假设在三个大的非临床样本(1)2,011名新兵，(2)1,296名大学生和(3)399名高中生中进行了检验，与传统的自杀风险模型相反，一维的冲动测量无法区分未遂者和自杀行为者--只有在实施了多维冲动测量的样本2和3中(即，UPPS冲动行为量表，Whiteside&Lynam，2001)不同的冲动相关特质是企图者和理想者的特征--只有企图者和理想者表现出高度的紧迫感(面对负面情绪时冲动的倾向)，只有企图者表现出糟糕的预谋(思考行为后果的能力减弱)既不表现出高度的感觉追求，也不表现出缺乏毅力未来的研究应该继续区分预测自杀意念的冲动相关特征和预测自杀企图的冲动相关特征，自杀风险模型应该进行相应的修正
Elevated impulsivity is thought to facilitate the transition from suicidal thoughts to suicidal behavior Therefore, impulsivity should distinguish those who have attempted suicide (attempters) from those who have only considered suicide (ideators-only) This hypothesis was examined in three large nonclinical samples (1) 2,011 military recruits, (2) 1,296 college students, and (3) 399 high school students In sample 1, contrary to traditional models of suicide risk, a unidimensional measure of impulsivity failed to distinguish attempters from ideators-only In samples 2 and 3, which were administered a multidimensional measure of impulsivity (i e, the UPPS impulsive behavior scale, Whiteside & Lynam, 2001), different impulsivity-related traits characterized attempters and ideators-only Whereas both attempters and ideators-only exhibited high urgency (the tendency to act impulsive in the face of negative emotions), only attempters exhibited poor premeditation (a diminished ability to think through the consequences of one's actions) Neither attempters nor ideators-only exhibited high sensation seeking or lack of perseverance Future research should continue to distinguish impulsivity-related traits that predict suicide ideation from those that predict suicide attempts, and models of suicide risk should be revised accordingly
