Previous studies investigating the relationship between nightmares and suicidal ideation have been equivocal. In this study, we investigated the role of nightmare distress in the relationship between nightmare frequency and suicidal ideation. Study participants were 280 undergraduate students (Mage 21.84, 2.14 SD, 77.9% women), who answered “yes” to experiencing nightmares in the past year. All participants completed questionnaires on nightmare frequency (Nightmare Frequency Questionnaire), nightmare distress (Nightmare Distress Questionnaire), suicidal ideation (Depressive Symptom Inventory—Suicidality Subscale), and insomnia (Insomnia Severity Index). Mediation analyses determined that nightmare distress fully mediated the relationship between nightmare frequency and suicidal ideation after controlling for insomnia. Although the total effect on the relationship between nightmare frequency and suicidal ideation (B .21, SE .08, p .009), the direct effects of nightmare frequency on suicidal ideation were not significant after accounting for the effects of nightmare distress and insomnia (B .12, SE .08, p .16). Additionally, the indirect effect of nightmare distress on the relationship between nightmare frequency and suicidal ideation was significant bootstrapped 95% confidence interval (CI) [0.0306, 0.1946]. Finally, gender moderated the mediated effect of nightmare distress between nightmare frequency and suicidal ideation. Our results support that both nightmare frequency and nightmare distress should be evaluated in clinical and research settings, especially for women, in the context of suicidal risk assessment.

噩梦痛苦作为噩梦频率和自杀意念之间的中介。

先前调查噩梦和自杀意念之间关系的研究一直模棱两可。在这项研究中,我们调查了噩梦困扰在噩梦频率和自杀意念之间关系中的作用。研究参与者是 280 名本科生(法师 21.84,2.14 SD,77.9% 女性),他们在过去一年中经历过噩梦,回答“是”。所有参与者完成了关于噩梦频率(Nightmare Frequency Questionnaire)、噩梦困扰(Nightmare Distress Questionnaire)、自杀意念(Depressive Symptom Inventory-Suicideity Subscale)和失眠(Insomnia Severity Index)的问卷。中介分析确定,在控制失眠后,噩梦困扰完全中介了噩梦频率与自杀意念之间的关系。尽管对噩梦频率和自杀意念之间关系的总影响 (B .21, SE .08, p .009),但在考虑了噩梦困扰和失眠的影响后,噩梦频率对自杀意念的直接影响并不显着( B .12,SE .08,第 .16 页)。此外,噩梦困扰对噩梦频率和自杀意念之间关系的间接影响是显着的 95% 置信区间 (CI) [0.0306, 0.1946]。最后,性别在噩梦频率和自杀意念之间调节了噩梦困扰的中介效应。我们的结果支持在自杀风险评估的背景下,应在临床和研究环境中评估噩梦频率和噩梦痛苦,尤其是对女性。
