This study examines relationships between affect and sleep in youth with affective disorders using ecological momentary assessment (EMA).
Participants included 94 youth, ages 8-16 (M = 11.73, 53% female) years with an anxiety disorder only (n = 23), primary major depressive disorder (with and without a secondary anxiety diagnoses; n = 42), and healthy controls (n = 29). A cell phone EMA protocol assessed affect and actigraphy measured sleep.
The patterns of bidirectional relationships between affect and sleep differed across diagnostic groups. Higher daytime positive affect and positive to negative affect ratios were associated with more time in bed during the subsequent night for youth with primary depression and less time in bed for youth with anxiety only. More time asleep was associated with more positive affect for both diagnostic groups the following day.
This relationship may be important to consider in the treatment of youth affective disorders.
本研究采用生态瞬时评估（EMA）方法，探讨情感障碍青少年的情绪与睡眠之间的关系。
参与者包括 94 名 8-16 岁（M=11.73，53%为女性）的青少年，其中包括单纯焦虑障碍（n=23）、原发性主要抑郁障碍（伴或不伴二级焦虑诊断；n=42）和健康对照组（n=29）。手机 EMA 方案评估了情绪，而活动记录仪则测量了睡眠。
在不同的诊断组中，情绪与睡眠之间的双向关系模式存在差异。对于原发性抑郁的青少年，白天的积极情绪和积极到消极情绪比值较高，与随后晚上在床上的时间较长有关；而对于仅有焦虑的青少年，床上的时间较短。对于两个诊断组来说，更多的睡眠时间都与次日更多的积极情绪有关。
在青少年情感障碍的治疗中，这种关系可能是需要考虑的重要因素。
