Abstract

This study sought to examine predictors of subjective/objective sleep discrepancy in poor sleepers. Forty-two individuals with insomnia symptoms (mean age = 36.2 years, 81% female) were recruited to take part in a prospective study which combined seven days of actigraphy with daily assessment of sleep perceptions, self-reported arousal, sleep effort, and mood upon awakening. A high level of intra-individual variability in measures of sleep discrepancy was observed. Multilevel modelling revealed that higher levels of pre-sleep cognitive activity and lower mood upon awakening were significantly and independently predictive of the underestimation of total sleep time. Greater levels of sleep effort predicted overestimation of sleep onset latency. These results indicate that psychophysiological variables are related to subjective/objective sleep discrepancy and may be important therapeutic targets in the management of insomnia.

摘要

本研究旨在探讨睡眠不佳者主观/客观睡眠差异的预测因素。招募了42名有失眠症状的个体(平均年龄 = 36.2岁,81%为女性)参与一项前瞻性研究,该研究将七天的活动记录仪监测与对睡眠感知、自我报告的觉醒程度、睡眠努力程度以及醒来时情绪的每日评估相结合。观察到睡眠差异测量中个体内部存在高度变异性。多水平模型显示,睡前认知活动水平较高以及醒来时情绪较低显著且独立地预测了总睡眠时间的低估。更高水平的睡眠努力程度预测了入睡潜伏期的高估。这些结果表明,心理生理变量与主观/客观睡眠差异有关,可能是失眠管理中的重要治疗靶点。
