The present study examined the dynamic associations among daily stress levels, affect, and objective sleep quality in adolescence. We also explored loneliness as a potential moderator of these associations. Seventy-eight adolescents participated over three days. They completed diary reports of stressful experiences and affect five times a day while wearing an actigraph to obtain objective measurement of sleep. They also provided self-reports of loneliness. High daily stress was associated with shorter sleep duration. Models testing bidirectional associations indicated that prior day stress was associated with shorter sleep duration, but poor sleep duration and sleep efficiency were also associated with greater stress the next day. Loneliness was a significant moderator of the associations between daily stress and sleep duration and latency such that lonely individuals had shorter sleep durations and sleep latencies after particularly stressful days. Results suggest daily dynamic associations among loneliness, daily stress, and objective measures of adolescent sleep.
本研究考察了青少年时期日常压力水平、情绪和客观睡眠质量之间的动态关联。我们还探讨了孤独感作为这些关联的潜在调节因素。78 名青少年参与了为期三天的研究。他们每天五次完成日记报告，记录压力经历和情绪，同时佩戴活动记录仪以获得客观的睡眠测量。他们还报告了自己的孤独感。高日常压力与睡眠时间较短有关。检验双向关联的模型表明，前一天的压力与睡眠时间较短有关，但较差的睡眠持续时间和效率也与第二天更大的压力有关。孤独感是日常压力和睡眠时间及潜伏期之间关联的重要调节因素，因此孤独的个体在压力特别大的日子后睡眠时间和潜伏期较短。研究结果表明，孤独感、日常压力和青少年睡眠的客观测量之间存在日常动态关联。
