This investigation assessed the efficacy of a technique specifically designed to change the style and content of presleep thoughts in order to reduce nighttime cognitive arousal and decrease insomnia severity. This investigation, termed "cognitive refocusing treatment for insomnia" (CRT-I), previously improved sleep in a small sample of veterans with primary insomnia. In this investigation, university students with poor sleep were randomly assigned to attend either one session of CRT-I and sleep hygiene education (SH: n=27) or one session of only SH (n=24). Insomnia severity (assessed by the Insomnia Severity Index) and nighttime arousal (assessed by the Pre-Sleep Arousal Scale) were measured at baseline and 1month posttreatment. A significant Group×Time interaction for insomnia severity suggested more improved sleep over time for those receiving CRT-I+SH. A trend for a Group×Time interaction showed decreased cognitive arousal over time among those receiving CRT-I. These findings provide preliminary support for the efficacy of CRT-I for insomnia treatment among college students. Continued study of CRT-I in a community-based sample appears warranted.
本研究评估了一种专门设计的技术的疗效，该技术旨在改变睡前思维的方式和内容，以减少夜间认知觉醒并降低失眠严重程度。这项名为“失眠认知重定向治疗”（CRT-I）的研究之前已在一小部分原发性失眠的退伍军人中改善了睡眠。在这项研究中，睡眠质量差的大学生被随机分配参加 CRT-I 和睡眠卫生教育（SH）（n=27）或仅参加 SH（n=24）的一次课程。在基线和治疗后 1 个月测量失眠严重程度（用失眠严重程度指数评估）和夜间觉醒（用睡前觉醒量表评估）。失眠严重程度的组间×时间交互作用显著，表明接受 CRT-I+SH 的患者睡眠改善更明显。组间×时间的趋势显示，接受 CRT-I 的患者认知觉醒随时间逐渐降低。这些发现为 CRT-I 治疗大学生失眠的疗效提供了初步支持。在基于社区的样本中进一步研究 CRT-I 似乎是合理的。
