Insomnia symptoms have been shown to be associated with suicide ideation/behavior. However, the underlying mechanism is unclear and studies on protective factors that might mitigate the association between sleep-related problems and suicide ideation/behavior are largely missing. On this background the aim of the current study was to investigate, whether positive mental health (PMH) accounts for the association between insomnia symptoms and suicidal ideation/behavior. A total of 913 participants (72.2% women; age: = 25.91 (7.08)) completed measures on insomnia symptoms, PMH and suicide ideation/behavior via an online survey. The results reveal a significant association between insomnia symptoms and PMH. Both variables were significantly linked to lifetime suicide ideation/behavior and 12-month suicide ideation. Moreover, the association between insomnia symptoms and suicide-related outcomes was significantly mitigated by PMH. The current findings complement previous studies on the association between insomnia symptoms and suicide ideation/behavior. Furthermore, they demonstrate that PMH can mitigate the risk of suicide-related outcomes. Therapeutic intervention targeting insomnia symptoms and fostering PMH might be useful in the prevention of suicide ideation/behavior.

积极的心理健康解释了失眠症状与自杀相关结果之间的关系


失眠症状已被证明与自杀意念/行为有关。然而，其根本机制尚不清楚，并且对可能减轻睡眠相关问题与自杀意念/行为之间关联的保护因素的研究也基本上缺失。在此背景下，本研究的目的是调查积极心理健康（PMH）是否可以解释失眠症状与自杀意念/行为之间的关联。共有 913 名参与者（72.2% 为女性；年龄：= 25.91 (7.08)）通过在线调查完成了失眠症状、PMH 和自杀意念/行为的测量。结果显示失眠症状与 PMH 之间存在显着关联。这两个变量都与终生自杀意念/行为和 12 个月自杀意念显着相关。此外，PMH 显着减轻了失眠症状与自杀相关结果之间的关联。目前的研究结果补充了之前关于失眠症状与自杀意念/行为之间关联的研究。此外，他们证明 PMH 可以降低自杀相关结果的风险。针对失眠症状和促进 PMH 的治疗干预可能有助于预防自杀意念/行为。
