This study investigated: i) the effects of loneliness on self-reported sleep outcomes and daily stress/hassles, ii) whether the effects of loneliness on sleep outcomes were mediated through prior-day stress/hassles and iii) if the effects of loneliness on daily stress/hassles were mediated through prior-night sleep measures. Using a 7-day diary design, this study aimed to investigate relationships between loneliness, daily sleep outcomes and daily stress/hassles. Participants (N = 174, M 19.95, 86.2% female) completed the UCLA Loneliness Scale once before a 7-day online diary twice per day. Measures of daily stress and hassles were completed before bed and sleep outcomes the following day. Multilevel modelling found higher levels of loneliness were associated with poorer sleep quality, greater pre-sleep arousal, morning tiredness, fewer total hours slept and higher levels of daily stress and hassles across the 7-day study. Loneliness was found also to have indirect effects on sleep quality, pre-sleep arousal and morning tiredness through prior-day daily stress and hassles. In addition, loneliness also had indirect effects on daily stress and hassles through prior night sleep measures. The current findings suggest that interventions aimed at mitigating the effects of loneliness should also incorporate components that target modifiable risk factors such as sleep and stress.
i）孤独感对自我报告的睡眠结果和日常压力/麻烦的影响，ii）孤独感对睡眠结果的影响是否通过前一天的压力/麻烦来介导，以及 iii）孤独感对日常压力/麻烦的影响是否通过前一晚的睡眠测量来介导。本研究采用 7 天日记设计，旨在调查孤独感、日常睡眠结果和日常压力/麻烦之间的关系。参与者（N=174，M 19.95，86.2%为女性）在 7 天的在线日记中每天两次完成一次 UCLA 孤独感量表。在睡前和第二天完成日常压力和麻烦的测量以及睡眠结果。多层次模型发现，孤独感水平越高，睡眠质量越差，睡前觉醒程度越高，早晨疲劳感越重，总睡眠时间越少，日常压力和麻烦水平越高。孤独感还通过前一天的日常压力和麻烦对睡眠质量、睡前觉醒和早晨疲劳产生间接影响。此外，孤独感也通过前夜的睡眠测量对日常压力和麻烦产生间接影响。目前的研究结果表明，旨在减轻孤独感影响的干预措施也应纳入针对可改变的风险因素（如睡眠和压力）的组成部分。
