Abstract

Insomnia is a risk factor for suicidal thoughts and behaviors. The present study examined the role of pre-sleep arousal in this association. Seventy-eight adults ( = 24.28, 56% had recent history of suicidal thoughts and behaviors) attended two lab visits over four consecutive days. We tested if generally experienced self-reported pre-sleep arousal explained the association between self-report insomnia symptoms experienced over the past two weeks and past week-suicidal ideation. Results indicated full mediation for pre-sleep cognitive arousal, but not somatic arousal. Pre-sleep cognitive arousal could be a key variable linking insomnia symptoms to suicide risk.

摘要

失眠是自杀意念和行为的一个风险因素。本研究考察了睡前觉醒在这一关联中的作用。78 名成年人(=24.28,56%有近期自杀念头和行为史)在连续四天的两次实验室访问中接受了测试。我们测试了自我报告的睡前觉醒是否可以解释过去两周内自我报告的失眠症状与过去一周自杀意念之间的关联。结果表明,睡前认知觉醒完全中介,而躯体觉醒则不完全中介。睡前认知觉醒可能是将失眠症状与自杀风险联系起来的关键变量。
