Abstract

Introduction: Sleep disorder symptoms are associated with suicidal ideation, and wakefulness in the middle of the night is associated with an increased risk for suicide, potentially due to deficits in cognitive control. Little is known about daily-level associations among sleep and suicide or about the role of cognitive control in these associations.

Methods: Veterans (n = 32) with past-month suicidal ideation in a residential treatment unit were assessed for 28 days using the suicide visual analogue scale (S-VAS) to assess suicidal urges, a daily sleep diary, and self-reported cognitive control.

Results: Wakefulness in the middle of the night (1-4 a.m.) was associated with the most severe suicidal ideation. Nocturnal wakefulness and sleep quality were each associated with next-day suicidal ideation intensity. Self-reported cognitive control deficits were associated with more intense suicidal ideation. The association between nocturnal wakefulness and suicidal ideation was partially accounted for by self-reported impulsive behavior (7% of variance).

Conclusions: Veterans reported the highest suicidal ideation in the middle of the night. These findings suggest the importance of assessing sleep, suicidal ideation, and cognitive control among veterans and the need to consider nocturnal wakefulness as an indicator of heightened risk for suicide among veterans.

自杀意念、认知控制和睡眠在住院治疗机构退伍军人：一项试点研究。

睡眠障碍症状与自杀意念有关，而半夜醒来与自杀风险增加有关，这可能是由于认知控制缺陷所致。人们对睡眠和自杀之间的日常联系知之甚少，也不清楚认知控制在这些联系中的作用。方法：使用自杀视觉模拟量表（S-VAS）评估自杀冲动、每日睡眠日记和自我报告的认知控制，对住院治疗单位中过去一个月有自杀意念的退伍军人（n = 32）进行28天的评估。结果：半夜（凌晨1-4点）醒着与最严重的自杀意念相关。夜间清醒程度和睡眠质量均与次日自杀意念强度相关。自我报告的认知控制缺陷与更强烈的自杀意念有关。夜间清醒和自杀意念之间的关联部分归因于自我报告的冲动行为（方差的7%）。结论：退伍军人报告的自杀意念在半夜最高。这些发现表明，评估退伍军人睡眠、自杀意念和认知控制的重要性，以及将夜间清醒作为退伍军人自杀风险增加的一个指标的必要性。

期刊介绍： An excellent resource for researchers as well as students, Social Cognition features reports on empirical research, self-perception, self-concept, social neuroscience, person-memory integration, social schemata, the development of social cognition, and the role of affect in memory and perception. Three broad concerns define the scope of the journal: - The processes underlying the perception, memory, and judgment of social stimuli - The effects of social, cultural, and affective factors on the processing of information - The behavioral and interpersonal consequences of cognitive processes.
