Prior research has observed reciprocal associations between sleep and mood. However, these findings are primarily based on the examination of one or two aspects of sleep behaviors (e.g., duration, quality), neglecting how multiple dimensions of sleep (particularly indicators pertinent to adolescence, e.g., sleep variability) are linked to adolescent mood both daily and longitudinally. Drawing on a multidimensional framework for sleep, this study addressed the knowledge gap by examining the directionality of and differential effects for associations between multiple dimensions of sleep and mood during early adolescence. Participants were 273 Chinese early adolescents (34.39% girls; M = 11.57, SD = 1.31), who filled out a pre-survey on demographics (T1) and 7-day diaries on sleep (i.e., duration, quality, disturbance, and latency) and mood (i.e., positive and negative mood). Adolescents completed another wave of diary reports 1 year later (T2). Findings revealed both bidirectional and unidirectional, within-person effects depending on specific sleep parameters, suggesting differential associations between multiple dimensions of sleep and mood. Specifically, on days when adolescents had longer sleep latency and greater disturbance than usual, they reported higher negative mood the next day, whereas higher negative mood was linked to poorer sleep quality the next day. The longitudinal investigation found that greater variability in sleep quality at T1 was associated with higher negative mood at T2. These findings underscore the importance of understanding the complex interplay between sleep and mood by examining the directionality of and differential effects for the daily and longer-term associations between multiple dimensions of sleep and mood among early adolescents.
先前的研究观察到睡眠和情绪之间存在相互关联。然而，这些发现主要基于对睡眠行为的一个或两个方面的检查（例如，持续时间、质量），而忽略了睡眠的多个维度（特别是与青少年有关的指标，例如睡眠变异性）如何与青少年的情绪在日常和长期都相关联。本研究借鉴了睡眠的多维框架，通过检查多个维度的睡眠和情绪在青少年早期之间的关联的方向性和差异效应，填补了这一知识空白。参与者是 273 名中国青少年（34.39%的女孩；M=11.57，SD=1.31），他们填写了关于人口统计学（T1）和睡眠（即持续时间、质量、干扰和潜伏期）和情绪（即积极和消极情绪）的 7 天日记的预调查。青少年在 1 年后（T2）完成了另一波日记报告。研究结果显示，根据特定的睡眠参数，存在双向和单向的个体内效应，这表明睡眠和情绪的多个维度之间存在不同的关联。具体而言，当青少年的睡眠潜伏期和干扰比平时更长时，他们第二天报告的负面情绪更高，而更高的负面情绪与第二天的睡眠质量较差有关。纵向研究发现，T1 时睡眠质量的更大变异性与 T2 时更高的负面情绪有关。这些发现强调了通过检查多个维度的睡眠和情绪之间的日常和长期关联的方向性和差异效应来理解睡眠和情绪之间复杂相互作用的重要性。
