Sleep disturbance is a core symptom of mood disorders. However, surprisingly little is known about the relationship between sleep quality and ambulatory daily mood, especially in mood-disordered populations. We assessed ambulatory positive affect (PA) and negative affect (NA) 10 times daily for three consecutive days with the computerized experience sampling method among persons with major depression (n = 35), minor depression (n = 25) and healthy controls (n = 36). Sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI). Poorer sleep quality predicted lower ambulatory PA, even after accounting for the effects of diagnostic group and self-reported anxiety. Conversely, sleep quality did not predict ambulatory NA once diagnostic group was accounted for. Analyzes of specific PSQI component scores indicated that poor subjective sleep quality and self-reported daytime dysfunction were the sleep components most strongly tied to reports of low ambulatory PA. Impaired sleep quality may be responsible for reduced pleasurable experience in everyday life.
睡眠障碍是情绪障碍的核心症状。然而，令人惊讶的是，人们对睡眠质量与日常活动中的情绪之间的关系知之甚少，尤其是在情绪障碍人群中。我们使用计算机化的经验采样方法，连续三天每天 10 次评估重度抑郁症患者（n = 35）、轻度抑郁症患者（n = 25）和健康对照组（n = 36）的日常积极情绪（PA）和消极情绪（NA）。使用匹兹堡睡眠质量指数（PSQI）评估睡眠质量。即使考虑到诊断组和自我报告的焦虑的影响，睡眠质量较差也预示着日常活动中的 PA 较低。相反，一旦考虑到诊断组，睡眠质量就不能预测日常活动中的 NA。对 PSQI 特定成分得分的分析表明，主观睡眠质量差和自我报告的日间功能障碍是与日常活动中 PA 较低报告最相关的睡眠成分。睡眠质量受损可能是导致日常生活中愉悦体验减少的原因。
