BackgroundThe objective of this systematic review is to describe the scientific evidence for the Suicide Crisis Syndrome (SCS), a presuicidal cognitive and affective state consisting of five symptomatic dimensions: entrapment, affective disturbance, loss of cognitive control, hyperarousal, and social withdrawal. The aim of this article is to summarize the emerging literature on the SCS and to assess the extent to which a uniform syndrome can be assumed.MethodsA systematic literature search was conducted in three different databases (PubMed, PsycInfo, and Google Scholar) using the search terms “Suicide Crisis Inventory,” “Suicide Crisis Syndrome,” “Narrative Crisis Model of Suicide,” and “Suicide Trigger State.”ResultsIn total, 37 articles from 2010 to 2022 were identified by search criteria. Twenty‐one articles published between 2017 and 2022 were included in the systematic review. All but three studies were conducted in the United States and examined clinical samples of adult high‐risk psychiatric in‐ and outpatients. Sample sizes ranged from N = 170 to 4846. The findings confirm the unidimensional structure of the proposed disorder and support the predictive validity for short‐term suicidal behavior above and beyond suicidal ideation.ConclusionDespite the promising predictive validity of the SCS, a precise prediction of future suicidal behavior remains difficult.

自杀危机综合症：系统评价

背景本系统综述的目的是描述自杀危机综合症（SCS）的科学证据，这是一种自杀前的认知和情感状态，由五个症状维度组成：受困、情感障碍、认知控制丧失、过度警觉和社交退缩。本文的目的是总结有关 SCS 的新兴文献，并评估可以假设统一综合征的程度。方法使用搜索在三个不同的数据库（PubMed、PsycInfo 和 Google Scholar）中进行系统文献检索术语“自杀危机量表”、“自杀危机综合症”、“自杀叙事危机模型”和“自杀触发状态”。结果通过搜索标准，总共识别出 2010 年至 2022 年的 37 篇文章。2017年至2022年间发表的21篇文章被纳入系统评价。除三项研究外，所有研究均在美国进行，并检查了成人高危精神病住院和门诊患者的临床样本。样本大小范围为氮= 170 至 4846。研究结果证实了所提出的疾病的一维结构，并支持对自杀意念之外的短期自杀行为的预测有效性。结论尽管 SCS 的预测有效性很有希望，但对未来自杀行为的精确预测仍然很困难。
