Abstract

Eveningness has been associated with both disturbed sleep and depression. It is unclear, however, if deprived sleep explains evening types' vulnerability to depression. The role of pre-sleep rumination in these associations also remains understudied. The present study assessed the relationship between eveningness and sleep quality, as well as the possible mediating effect of pre-sleep rumination and the moderating effect of a history of depression, under naturalistic conditions. Eighty-eight Dutch-speaking participants (87.5% females, 21.4 ± 3.7 years) were selected on the basis of their non-intermediate chronotype using the Morningness Eveningness Questionnaire (evening types (n = 53); morning types (n = 35)). Depression status was assessed through a diagnostic interview (healthy (n = 61); remitted depressed (n = 27)). Participants' sleep characteristics were monitored via actigraphy and sleep diaries for seven consecutive days and nights. Pre-sleep rumination was measured via a self-report questionnaire. Evening types had longer subjective and actigraphic sleep onset latency than morning types. Pre-sleep rumination did not mediate the former associations but predicted longer subjective sleep onset latency. Furthermore, the relationship between chronotype and subjective sleep onset latency was moderated by depression history. Remitted depressed evening types reported longer sleep onset latency than healthy evening and morning types, possibly posing the former at a higher risk for depressive relapse. Overall, the current findings address the need to further investigate the physiological signature of circadian rhythms and sleep latency. This could serve as a foundation for the development of prevention and early intervention programs, tailored for mood and sleep disorders.

时型、睡眠质量、抑郁和睡前遐想:一项日记和行动记录研究。
晚睡与睡眠紊乱和抑郁有关。然而,目前还不清楚睡眠不足是否是晚睡型易患抑郁症的原因。睡眠前的反刍在这些关联中的作用也仍未得到充分研究。本研究在自然条件下评估了晚睡与睡眠质量之间的关系,以及睡前反刍可能产生的中介效应和抑郁症病史可能产生的调节效应。88名荷兰语参与者(87.5%为女性,21.4±3.7岁)是根据他们的非中度时间型,使用晨昏度问卷(晚间型(53人);早晨型(35人))挑选出来的。抑郁状况通过诊断性访谈进行评估(健康(61 人);缓解型抑郁(27 人))。参与者的睡眠特征通过连续七昼夜的动觉仪和睡眠日记进行监测。睡前反刍通过自我报告问卷进行测量。晚睡型患者的主观睡眠起始潜伏期和动图睡眠起始潜伏期均长于早睡型患者。睡前反刍并不影响前者的相关性,但却能预测更长的主观睡眠开始潜伏期。此外,时间型与主观睡眠开始潜伏期之间的关系受抑郁史的调节。已痊愈的晚间抑郁类型比健康的晚间和早晨抑郁类型报告的睡眠开始潜伏期更长,这可能使前者面临更高的抑郁复发风险。总之,目前的研究结果表明,有必要进一步研究昼夜节律和睡眠潜伏期的生理特征。这将为开发针对情绪和睡眠障碍的预防和早期干预计划奠定基础。

期刊介绍: EJN is the journal of FENS and supports the international neuroscientific community by publishing original high quality research articles and reviews in all fields of neuroscience. In addition, to engage with issues that are of interest to the science community, we also publish Editorials, Meetings Reports and Neuro-Opinions on topics that are of current interest in the fields of neuroscience research and training in science. We have recently established a series of ‘Profiles of Women in Neuroscience’. Our goal is to provide a vehicle for publications that further the understanding of the structure and function of the nervous system in both health and disease and to provide a vehicle to engage the neuroscience community. As the official journal of FENS, profits from the journal are re-invested in the neuroscientific community through the activities of FENS.
