This study investigated the relationship between hyperarousal, sleep scheduling, and time awake in bed in a secondary data analysis. Participants were 89 adults with chronic insomnia previously involved in a randomized controlled trial of 5 weeks of computerized cognitive behavioral therapy (cCBT). At measurement periods, participants completed the Pre-Sleep Arousal Scale, 7 days of sleep diaries, and the Insomnia Severity Index. Measures were re-administered at a 4 week follow-up. Results showed that improvements in hyperarousal and time awake in bed partially mediated the impact of cCBT on sleep at follow-up but that improvements in sleep schedule consistency did not. Of these mediators, pre-sleep arousal is more significant in explaining change associated with cCBT for insomnia.
本研究在二次数据分析中调查了过度觉醒、睡眠安排和卧床时间之间的关系。参与者为 89 名患有慢性失眠症的成年人，他们之前曾参与过为期 5 周的计算机化认知行为疗法（cCBT）的随机对照试验。在测量期间，参与者完成了睡前觉醒量表、7 天的睡眠日记和失眠严重程度指数。在 4 周的随访中重新进行了测量。结果表明，过度觉醒和卧床时间的改善部分中介了 cCBT 对随访时睡眠的影响，但睡眠安排一致性的改善则没有。在这些中介因素中，睡前觉醒在解释与 cCBT 治疗失眠相关的变化方面更为重要。
