Suicide has a profound impact on individuals, families, and society. One prominent, if understudied, risk factor for suicide is anxiety. More than 70% of people with at least one suicide attempt meet diagnostic criteria for an anxiety disorder. There are several limitations to exploring the associations between anxiety and suicide using diagnosis-based classification systems. A better approach would be to consider transdiagnostic risk factors for anxiety.
Through a negative reinforcement model of suicide, anxiety sensitivity (AS) and intolerance of uncertainty (IU) appear to exacerbate the experience of unpleasant anxiety sensations and likely contribute to chronic suicide risk as well as acute suicidal acts. Although more research is needed to clarify the mechanisms through which AS and IU confer risk, brief interventions may offer an ideal suicide prevention strategy for anxious people.
自杀对个人、家庭和社会都有着深远的影响。焦虑是一个突出但研究不足的自杀风险因素。有至少一次自杀未遂的人中,超过 70%符合焦虑障碍的诊断标准。使用基于诊断的分类系统来探索焦虑与自杀之间的关系存在一些局限性。一种更好的方法是考虑焦虑的跨诊断风险因素。
通过自杀的负强化模型,焦虑敏感(AS)和不确定性容忍度(IU)似乎加剧了不愉快的焦虑感体验,并可能导致慢性自杀风险以及急性自杀行为。尽管需要更多的研究来阐明 AS 和 IU 带来风险的机制,但简短的干预措施可能为焦虑人群提供理想的自杀预防策略。
