Despite current knowledge of risk factors for suicidal behaviors, suicide remains a leading cause of death worldwide. This suggests a strong need to identify and understand additional risk factors. A number of recent studies have identified insomnia as a modifiable, independent suicide risk factor. Although a link between insomnia and suicide is emerging, further research is required in order to understand the nature of the relationship. Accordingly, this paper presents an overview of the insomnia and suicide literature to-date, and a discussion of two major limitations within this literature that hinder its progress. First, the classification and assessment of insomnia and suicide-related thoughts and behaviors are inconsistent across studies; and second, there is a lack of empirical studies focused on investigating mediators of the insomnia and suicide relationship. Suggestions are offered within this paper for future studies to address these issues and facilitate new developments in this important research area. Following these suggested lines of research will ultimately inform whether insomnia treatments, particularly cognitive-behavioral therapy for insomnia, can be used to target suicide risk prevention and intervention.
尽管目前已经了解了自杀行为的风险因素，但自杀仍然是全球范围内的主要死亡原因。这表明需要识别和理解更多的风险因素。最近的一些研究已经确定失眠是一个可改变的、独立的自杀风险因素。尽管失眠与自杀之间的联系正在显现，但仍需要进一步的研究来了解这种关系的本质。因此，本文对迄今为止的失眠和自杀文献进行了综述，并讨论了该文献中阻碍其进展的两个主要局限性。首先，失眠和自杀相关想法和行为的分类和评估在研究之间不一致；其次，缺乏关注调查失眠与自杀关系中介因素的实证研究。本文为未来的研究提供了建议，以解决这些问题，并促进这一重要研究领域的新发展。遵循这些研究建议最终将决定失眠治疗，特别是失眠的认知行为疗法，是否可以用于针对自杀风险的预防和干预。
