失眠病人之睡眠感受與情緒相關中介因素之研究

Sleep Perception and Mood in Insomnic Patients

目的：本研究於花蓮基督教門諾醫院招募以 DSM-IV 為診斷標準之原發性失眠病人為樣 本，調查的項目包括情緒、客觀的睡眠測量，和主觀睡眠感之間的關係。 方法：使用睡眠日 記和問卷來評估為期一週的主觀睡眠感，在此同時，也利用腕動計 (actigraphy) 來測量客觀 睡眠。情緒狀態則藉由自陳報告為工具來評估。 結果：布肯模式通常被用來計算變項和潛在 中介變項之間的強度。研究結果指出情緒及對睡眠的主觀感受是有顯著的 (p < 0.01)，且當 作中介變項之可被測量的客觀睡眠也有達到顯著 (p < 0.01)。 結論：若實際的睡眠時數減少 時，我們對於自身睡眠品質的認知，會對情緒造成相當重要的影響。

Objectives: In this study the authors intended to investigate the relation be-tween mood, objective sleep measurement, and subjective sleep perception; in a sample of patients diagnosed with DSM-IV insomnia we recruited in the Menno-nite Christian Hospital in Hualien. Methods: Sleep logs and questionnaires were used to measure subjective sleep perception for one week. Objective sleep mea-sures were also obtained using actigraphy for the concurrent period. Mood was assessed using self-report instruments. Results: Baron and Kenny’s model was used to calculate the strength of the relation of variables and explore potential me-diators. The results indicated that the association between mood and subjective sleep perception was significant (p < 0.01). This association was significantly me-diated by the objectively measured sleep (p < 0.01). Conclusion: Perception of our sleep quality impact mood in a significant manner if the actual sleep we have is reduced.
