背景资料：急性暴露（如酒精使用（Au）和负性生活事件（NLE））与自杀企图前数小时内自杀意念强度的唯一相关程度尚不清楚。本研究的主要目的是在调整前一小时的急性暴露和自杀意念时，量化急性暴露对下一小时自杀意念的独特影响。本研究的探索性目的是研究非酒精药物使用（DU）对自杀ideation.Methods的影响：参与者包括166（61.0%女性）最近的自杀倾向1级创伤医院。采用时间轴追踪方法评估自杀未遂前24 h内的急性暴露和自杀意念强度。（B= 0.20，p <0.01）和NLE（B= 0.58，p <0.01）唯一地预测了下一小时自杀意念的增加，超过和超过前一小时自杀意念，而急性DU没有。局限性：目前的研究方法提供了自杀企图之前的连续每小时快照，非常接近自杀发生的时间，但是回顾性的，因果关系无法推断。结论：了解到，在患者体内，Au和NLE预测自杀意念的近期增加具有实际效用，影响提供者的临床决策、安全问题和最终确定自杀风险水平。由爱思唯尔公司出版
Background: The extent to which acute exposures such as alcohol use (AU) and negative life events (NLE) are uniquely associated with intensity of suicidal ideation during the hours leading up to a suicide attempt is unknown. The main aim of the current study was to quantify the unique effect of acute exposures on next-hour suicidal ideation when adjusting for previous hour acute exposures and suicidal ideation. An exploratory aim of the current study was to examine the effect of non-alcohol drug use (DU) on suicidal ideation.Methods: Participants included 166 (61.0% female) recent suicide attempters presenting to a Level 1 trauma hospital. A timeline follow-back methodology was used to assess acute exposures and intensity of suicidal ideation within the 24 h prior to the suicide attempt.Results: Findings indicated that acute AU (b=.20, p < .01) and NLE (b=.58, p < .01) uniquely predicted increases in next-hour suicidal ideation, over and above previous hour suicidal ideation, whereas acute DU did not.Limitations: The current study's methodology provides continuous hourly snapshots prior to the suicide attempt, quite close to when it happened, but is retrospective and causality cannot be inferred.Conclusions: Understanding that, within a patient, AU and NLE predict near-term increases in suicidal ideation has practical utility impacting providers' clinical decision-making, safety concerns, and ultimate determination of level of risk for suicide.
