研究发现，重复的思维过程，如担忧和沉思，在几种疾病中起着重要作用；然而，这些认知过程尚未在失眠中得到检验。本研究通过考察：1)反刍和忧虑高、低者在主观睡眠测量上是否存在差异；2)反刍和忧虑在失眠中是否是不同的过程来探讨失眠中的反刍和忧虑。参与者（N = 242）被睡眠专家诊断为失眠障碍。参与者完成了焦虑和沉思的测量，并保持了两周的每日睡眠记录。多变量方差分析结果显示，焦虑没有主要影响；尽管高反刍者和低反刍者在睡眠效率、睡眠后觉醒率和睡眠质量等睡眠日志指标上存在差异。因子分析支持了反刍和担忧是独立构念的观点。之前的研究主要集中在失眠的担忧上，而这些发现表明，反刍对于理解睡眠障碍很重要。此外，尽管反刍和担忧都是重复的思维过程，但这些结果表明，它们是失眠中不同的过程，应该这样对待。结果讨论了关于失眠的认知行为疗法的治疗意义。
Research has found that repetitive thought processes, such as worry and rumination, play an important role in several disorders; however, these cognitive processes have not yet been examined in insomnia. This study explores rumination and worry in insomnia by examining: 1) whether those high and low on rumination and worry differ on subjective sleep measures, and 2) whether rumination and worry are distinct processes in insomnia. Participants (N = 242) were diagnosed with an insomnia disorder by sleep experts. Participants completed measures of worry and rumination and maintained a 2-week daily sleep log. Results of a multivariate analysis of variance found no main effect of worry; although high and low ruminators differed on several sleep log indices, including sleep efficiency, wakefulness after sleep onset and sleep quality. Factor analysis supported the idea that rumination and worry are separate constructs. Whereas previous research has focused on worry in insomnia, these findings suggest that rumination is important for understanding sleep disturbance. Further, although rumination and worry are both repetitive thought processes, these results indicate that they are distinct processes within insomnia and should be treated as such. The results are discussed with respect to treatment implications for Cognitive Behavioural Therapy for Insomnia.
