这项研究的目的是检验觉醒、痛苦和与睡眠有关的信念是否与失眠的维持有关。从普通人群中随机抽取样本（n = 3600）， 1936名参与者填写了基线和1年随访调查。采用Logistic回归研究1年内觉醒、焦虑和信念是否与睡眠状态（失眠：116例；睡眠差：222例；正常睡眠：529例；良好睡眠：234例）相关。采用聚类分析来评估是否有可能根据参与者的心理功能概况对他们进行分类。结果表明，对失眠、焦虑、抑郁和觉醒的长期负面影响的信念与失眠的维持显著相关（方差的18-72%）。在持续性失眠症患者中，91%属于在睡眠相关信念、焦虑、抑郁和觉醒方面得分较高的一类，9%属于在机制方面得分较低的一类。这项研究表明，与睡眠相关的信念、焦虑、抑郁和觉醒与持续失眠的维持有关，但这些机制往往同时发生在失眠症患者身上。(c) 2006 Elsevier Ltd.版权所有。
The purpose of this study was to examine whether arousal, distress, and sleep-related beliefs are related to the maintenance of insomnia. From a randomly selected sample from the general population (n = 3600), 1936 participants filled out a baseline and 1-year follow-up survey. Logistic regressions were used to investigate whether arousal, distress, and beliefs were related to sleep status (insomnia: n = 116; poor sleep: n = 222; normal sleep: n = 529; good sleep: n = 234) over 1 year. Cluster analysis was employed to assess whether it was possible to classify the participants based on their profiles of psychological functioning. The results showed that beliefs in the long-term negative consequences of insomnia, anxiety, depression, and arousal were significantly related to the maintenance of insomnia (18-72% of the variance). Of the individuals with persistent insomnia, 91% belonged to a cluster characterized by high scores on sleep-related beliefs, anxiety, depression, and arousal, and 9% to a cluster defined by low scores on the mechanisms. This study shows that sleep-related beliefs, anxiety, depression, and arousal are related to the maintenance of persistent insomnia, but also that these mechanisms often co-occur in individuals with insomnia.
