Suicide is a serious public health problem, and suicide rates are particularly high in South Korea. Insomnia has been identified as a risk factor for suicidal ideation; however, little is known about the mechanisms accounting for this relationship in this population. Based on the premise that insomnia can be lonely (e.g., being awake when everyone else is asleep), the purpose of this study was to examine whether greater insomnia severity would be associated with higher levels of thwarted belongingness and suicidal ideation, and whether thwarted belongingness would mediate the relationship between insomnia and suicidal ideation.
Predictions were tested in a sample of 552 South Korean young adults who completed self-report measures of insomnia severity, suicidal ideation, and thwarted belongingness.
Greater insomnia symptom severity was significantly and positively associated with thwarted belongingness and suicidal ideation. Mediation analyses revealed that thwarted belongingness significantly accounted for the relationship between insomnia severity and suicidal ideation.
These findings highlight the potential importance of monitoring and therapeutically impacting insomnia and thwarted belongingness to help reduce suicide risk.
自杀是一个严重的公共卫生问题，韩国的自杀率尤其高。失眠已被确定为自杀意念的一个风险因素；然而，对于该人群中这种关系的机制却知之甚少。基于失眠可能会让人感到孤独这一前提（例如，当其他人都睡着时自己却醒着），本研究的目的是检验失眠严重程度的增加是否会与更高水平的归属感缺失和自杀意念相关，以及归属感缺失是否会介导失眠与自杀意念之间的关系。
在552名完成了失眠严重程度、自杀意念和归属感缺失自我报告测量的韩国年轻人样本中对预测进行了检验。
更高的失眠症状严重程度与归属感缺失和自杀意念显著正相关。中介分析表明，归属感缺失显著解释了失眠严重程度与自杀意念之间的关系。
这些发现凸显了监测和治疗性干预失眠及归属感缺失以帮助降低自杀风险的潜在重要性。
