Developing techniques designed to minimize arousing cognitions during the evening may be important to help improve the treatment of insomnia. This investigation assessed an intervention that focused exclusively on enhancing cognitive refocusing at sleep onset to change the content and style of presleep cognitions in order to improve sleep. Individuals with primary insomnia (N=10; 90% male, mean age=49.2, SD=12.6) attended four weekly individual meetings. Sleep quality (the Pittsburgh Sleep Quality Index), insomnia severity (the Insomnia Severity Index), sleep parameters based on one week of sleep diaries, and arousing thought content, were compared at baseline, posttreatment, and at a 1-month follow-up. Adherence was high, and participants showed good ability to engage in the procedure. Significant improvements in sleep quality, insomnia severity, sleep onset latency, total sleep time, and arousing thought content were revealed. Large effect sizes were observed on the majority of sleep variables at follow-up. Preliminary results were encouraging regarding a technique that targets the refocusing of thoughts during the evening in order to improve sleep. Further study regarding the efficacy of this procedure is warranted.
开发旨在减少夜间唤醒认知的技术可能对改善失眠治疗很重要。本研究评估了一种专门针对增强睡眠起始时认知重聚焦的干预措施，以改变睡前认知的内容和方式，从而改善睡眠。10 名原发性失眠症患者（90%为男性，平均年龄=49.2，SD=12.6）参加了每周一次的 4 次个体会议。在基线、治疗后和 1 个月随访时，比较了睡眠质量（匹兹堡睡眠质量指数）、失眠严重程度（失眠严重程度指数）、基于一周睡眠日记的睡眠参数以及唤醒性思维内容。依从性高，参与者表现出很好的参与能力。睡眠质量、失眠严重程度、入睡潜伏期、总睡眠时间和唤醒性思维内容均有显著改善。在随访时，大多数睡眠变量的效应量都很大。针对晚上重新聚焦思维以改善睡眠的技术，初步结果令人鼓舞。需要进一步研究该程序的疗效。
