Efforts to establish an empirical basis for recommended sleep durations during adolescence need to take into account individual differences in optimum sleep, defined as the amount of sleep at which peak functioning is observed. A total of 419 adolescents ( = 15.03 years) with Mexican American backgrounds reported their nightly sleep duration and daily mood for a 2-week period at 1 or 2 waves of data collection, 1 year apart. Adolescents also completed an established measure of symptomatology. Multilevel modeling revealed a nonlinear association between sleep duration and next-day mood, whereby both too little and too much sleep were associated with elevated levels of daily distress. Significant individual differences in optimum sleep were observed such that younger adolescents and those with elevated levels of internalizing and total symptomatology evidenced greater sleep durations on nights before they reported their lowest levels of daily distress. Younger adolescents and those with higher internalizing and total symptomatology may need more sleep to reach their peak functioning the next day, at least in terms of daily mood.
为推荐的青少年睡眠时间建立经验基础的努力需要考虑到最佳睡眠的个体差异，最佳睡眠定义为观察到最佳表现的睡眠时间。共有 419 名具有墨西哥裔美国人背景的青少年（= 15.03 岁）在 1 或 2 次数据收集的 2 周时间内报告了他们的夜间睡眠时间和每日情绪，每次采集相隔 1 年。青少年还完成了一项既定的症状学测量。多层次模型显示，睡眠时间与次日情绪之间存在非线性关联，即睡眠过少和过多都与日常困扰水平升高有关。观察到最佳睡眠存在显著的个体差异，例如，年龄较小的青少年和那些具有较高内化和总症状学水平的青少年在报告日常困扰水平最低的前一天晚上睡眠时间更长。年龄较小的青少年和那些具有较高内化和总症状学水平的青少年可能需要更多的睡眠来达到第二天的最佳表现，至少在日常情绪方面是这样。
