我们试图对调查心理因素在睡眠问题与自杀想法和行为之间的关系中的作用的经验证据进行首次系统性综述。12项研究被确定为四类认知评价，心理因素，情绪调节策略和风险行为的心理因素进行了研究。尽管在测量、取样和分析方面，研究之间存在很大的异质性，但初步证据表明，负面的认知评价、感知到的社会孤立和无益的情绪调节策略可能有助于睡眠问题与自杀想法和行为之间的关联。鉴于这一领域的研究结果目前仅限于横断面设计的研究，这些心理因素，睡眠问题和自杀倾向之间的相互关系的方向性仍然不清楚。我们将我们的研究结果与当代自杀行为的心理模型相结合，以制定一个明确的研究议程。现在应该用纵向和实验性设计来测试已确定的途径。此外，对睡眠、心理因素以及自杀想法和行为的复杂性进行更彻底的调查，对于制定有针对性的心理干预措施至关重要。心理因素在睡眠/自杀关系中的作用的系统综述综述与自杀理论相结合的研究结果，以定义一个明确的研究议程。依赖横截面设计限制了对路径方向性的解释。应采用纵向和实验设计对已确定的途径进行研究。
We sought to conduct the first systematic review of empirical evidence investigating the role of psychological factors in the relationship between sleep problems and suicidal thoughts and behaviours. Twelve studies were identified which examined psychological factors grouped into four categories of cognitive appraisals, psychosocial factors, emotion regulation strategies, and risk behaviours. Although there was substantial heterogeneity across studies with respect to measurement, sampling, and analysis, preliminary evidence indicated that negative cognitive appraisals, perceived social isolation, and unhelpful emotion regulation strategies may contribute to the association between sleep problems and suicidal thoughts and behaviours. Given that findings in this area are currently restricted to studies with cross-sectional designs, the directionality of the interrelationships between these psychological factors, sleep problems and suicidality, remains unclear. We integrate the findings of our review with contemporary psychological models of suicidal behaviour to develop a clear research agenda. Identified pathways should now be tested with longitudinal and experimental designs. In addition, a more thorough investigation of the complexities of sleep, psychological factors, and suicidal thoughts and behaviours is crucial for the development of targeted psychological interventions. Systematic review of the role of psychological factors in sleep/suicide relationships Review findings integrated with suicide theory to define a clear research agenda. Reliance on cross-sectional designs limits interpretation of directionality of pathways. Identified pathways should be investigated with longitudinal and experimental designs.
