尽管有大量文献研究自杀相关结果的风险因素，但很少有研究调查自杀意念者采取自杀行动的风险。目前的研究旨在填补这一空白，通过检查获得性能力的作用，以及其假设的促进者，痛苦和挑衅事件（ppe），作为自杀连续体中个体行为的激励因素。报告自杀意念、自杀计划、无死亡意图的自杀企图或有死亡意图的自杀企图的大学生（N=546）完成了获得性自杀能力的测量，以及对ppe暴露的评估。我们的研究结果表明，获得性自杀能力并不能区分从观念到行动的个体。在评估的几个ppe中，非自杀性自我伤害的频率，以及儿童时期情感虐待、身体虐待和身体忽视的存在在各组之间都有显著差异，有自杀企图意图死亡的个人报告的水平最高。这些发现表明，在确定自杀风险的评估中，ppe可能是最重要的，而且，进一步地，对在自杀连续体中区分个体的获得性能力的效用提出了质疑。
Despite the large literature on risk factors for suicide-related outcomes, few studies have examined risk for acting on suicidal thoughts among suicide ideators. The current study aimed to fill this gap by examining the role of acquired capability, as well as its hypothesized facilitator, painful and provocative events (PPEs), as motivators for behavior among individuals along the suicide continuum. Undergraduates reporting suicidal ideation, suicide plans, suicide attempts without intent to die, or suicide attempts with intent to die (N=546) completed a measure of acquired capability for suicide, as well as assessments of exposure to PPEs. Our findings demonstrated that acquired capability for suicide did not distinguish between individuals falling along the ideation-to-action spectrum. Among the several PPEs assessed, the frequency of non-suicidal self-injury, and the presence of childhood emotional abuse, physical abuse, and physical neglect each significantly differentiated between groups, with individuals having a history of a suicide attempt with the intent to die reporting the highest levels. These findings implicate the PPEs that may be most important to assess in determining suicide risk, and, further, call into question the utility of acquired capability in differentiating between individuals along the suicide continuum.
