评估日常孤独感与随后的日间功能障碍感（表明睡眠质量差）之间的前瞻性关联。由215名成年人（平均年龄= 57.5岁，SD = 4.4）组成的基于人群的样本完成了三次连续的每日结束日记。日记问题探讨了睡眠持续时间，白天功能障碍（即，疲劳、低能量、困倦）、孤独、身体症状和抑郁情绪。还获得了慢性健康状况数据和体重指数。自回归交叉滞后面板模型被用来研究孤独和日间功能障碍之间的相互前瞻性关联的大小。非标准化路径系数调整种族/民族，睡眠时间，婚姻状况，家庭收入，慢性健康状况和健康症状的严重程度。孤独感的每日变化预测了随后的日间功能障碍感觉，B = 0.16，p <0.05，日间功能障碍预测了随后的孤独感，B = 0.07，p <0.05，校正了协变量。当抑郁情绪保持不变时，孤独继续预测随后的日间功能障碍。孤独感对日间功能障碍的影响与睡眠时间无关，这表明当个体感到更加社会孤立时，相同的睡眠时间不那么有益于健康。
To assess the prospective association between daily feelings of loneliness and subsequent feelings of daytime dysfunction indicative of poor sleep quality. Three consecutive end-of-day diaries were completed by a population-based sample of 215 adults (mean age = 57.5 years, SD = 4.4). Diary questions probed sleep duration, daytime dysfunction (i.e., fatigue, low energy, sleepiness), loneliness, physical symptoms, and depressed affect experienced that day. Chronic health condition data and body mass index were also obtained. Autoregressive cross-lagged panel models were used to examine the magnitude of reciprocal prospective associations between loneliness and daytime dysfunction. Unstandardized path coefficients adjusted for race/ethnicity, sleep duration, marital status, household income, chronic health conditions, and health symptom severity. Daily variations in loneliness predicted subsequent feelings of daytime dysfunction, B = 0.16, p < .05, and daytime dysfunction predicted subsequent loneliness, B = 0.07, p < .05, adjusted for covariates. Loneliness continued to predict subsequent daytime dysfunction when depressed affect was held constant. The effect of loneliness on daytime dysfunction was independent of sleep duration, suggesting that the same amount of sleep is less salubrious when individuals feel more socially isolated.
