This study examined bidirectional associations between daily happiness and negative mood and subjective and objective sleep measures. Participants were 311 adolescents (M_age = 17.37 years; 51.8% female; 59.2% White/European American, 38.6% Black/African American, 1% Hispanic/Latinx American, 1.4% multi-racial; 19.3% below poverty line) observed over a 7-day period (2017–2018) using sleep diaries and actigraphy. Daily negative mood was related to greater subjective sleep/wake problems, and happiness was related to lower subjective sleep/wake problems. Conversely, shorter self-reported sleep duration was related to higher negative mood the next day. For actigraphy measures, daily negative mood was related to greater sleep duration and efficiency, whereas happiness was related to lower sleep efficiency. Differences in associations based on subjective versus objective sleep measures are discussed.

青少年夜间睡眠与日常幸福感和消极情绪之间的双向关联

这项研究检查了日常幸福感和消极情绪以及主观和客观睡眠测量之间的双向关联。参与者是 311 名青少年（M_年龄 = 17.37 岁；51.8% 女性；59.2% 白人/欧洲裔美国人，38.6% 黑人/非洲裔美国人，1% 西班牙裔/拉丁美洲裔美国人，1.4% 多种族；使用睡眠日记和活动记录仪在 7 天（2017-2018 年）期间观察到低于贫困线的 19.3%。日常消极情绪与较大的主观睡眠/清醒问题有关，而幸福感与较低的主观睡眠/清醒问题有关。相反，较短的自我报告睡眠时间与第二天较高的负面情绪有关。对于活动记录测量，每日消极情绪与更长的睡眠时间和效率有关，而快乐与更低的睡眠效率有关。讨论了基于主观与客观睡眠测量的关联差异。
