Suicide and self-harm behaviours represent public health concerns, and university students are a particularly high risk group. Identifying modifiable risk factors for the development and maintenance of suicidal thoughts and behaviours is a research priority, as prevention is crucial. Research examining the relationship between poor sleep and self-harm/suicidality within university students is, for the first time, systematically evaluated, critically appraised, and synthesised. This literature consistently demonstrates that insomnia and nightmares are associated with elevated suicide risk of suicidal thoughts and behaviours within this subpopulation of young adults. However, as findings are predominantly derived from cross-sectional investigations, the directionality of this relationship is not yet clear. While research investigating the psychological processes driving these relationships is in its infancy, preliminary findings suggest that thwarted belongingness, socio-cognitive factors and emotional dysregulation could be partly responsible. Methodological limitations are highlighted and a research agenda suggesting the key directions for future research is proposed. Continued research in this area - employing longitudinal designs, and testing novel theoretically derived hypotheses - will be crucial to the development of suicide prevention and intervention efforts.
自杀和自残行为是公共卫生关注的问题，而大学生是一个特别高风险的群体。确定自杀想法和行为的发展和维持的可改变风险因素是研究的重点，因为预防至关重要。研究首次系统地评估、批判性评价和综合了大学生中睡眠质量差与自我伤害/自杀之间的关系。这些研究一致表明，失眠和噩梦与该年轻人群体自杀想法和行为的自杀风险升高有关。然而，由于研究结果主要来自横断面研究，因此该关系的方向尚不清楚。虽然研究心理过程驱动这些关系的研究还处于起步阶段，但初步研究结果表明，归属感受挫、社会认知因素和情绪调节障碍可能是部分原因。本文强调了方法学的局限性，并提出了一个研究议程，为未来的研究提出了关键方向。在该领域持续进行研究——采用纵向设计，测试新的理论推导假设——对于制定自杀预防和干预措施至关重要。
