Sleep, or a lack thereof, is strongly related to mood dysregulation. Although considerable research uses symptom scales to examine this relation, few studies use longitudinal, real-time methods focused on pediatric irritability. This study leveraged an ecological momentary assessment (EMA) protocol, assessing bidirectional associations between momentary irritability symptoms and daily sleep duration in a transdiagnostic pediatric sample enriched for irritability.
A total of N = 125 youth (M = 12.58 years, SD = 2.56 years; 74% male; 68.8% White) completed digital, in vivo surveys three times a day for 7 days. For a subset of youth, their parents also completed the EMA protocol. Trait irritability was measured using youth-, parent-, and clinician-report to test its potential moderating effect on the association between sleep duration and momentary irritability.
Results from multilevel modeling dynamically linked sleep to irritability. Specifically, according to youth- and parent-report, decreased sleep duration was associated with increased morning irritability (bs ≤ -.09, ps < .049). A bidirectional association between parent-reported nightly sleep duration and anger was found-increased evening anger related to decreased nightly sleep duration, and decreased sleep duration related to increased morning anger (bs ≤ -.17, ps < .019). Trait irritability moderated this association, which was stronger for more irritable youth (b = -.03, p < .027).
This study adds to the literature and suggests sleep-irritability dynamics as a potential treatment target.
睡眠，或睡眠不足，与情绪失调密切相关。尽管大量研究使用症状量表来研究这种关系，但很少有研究使用关注儿科易怒症的纵向、实时方法。本研究利用生态瞬时评估（EMA）方案，在易激惹的儿科综合性样本中评估了瞬时易怒症状与每日睡眠时间之间的双向关联。
共有 125 名青少年（M=12.58 岁，SD=2.56 岁；74%为男性；68.8%为白人）每天完成三次共 7 天的数字、现场调查。对于一部分青少年，他们的父母也完成了 EMA 方案。使用青少年、父母和临床医生报告的特质易激惹来衡量其对睡眠持续时间和瞬时易激惹之间的关联的潜在调节作用。
多层次建模的结果动态地将睡眠与易激惹联系起来。具体来说，根据青少年和父母的报告，睡眠持续时间减少与早晨易激惹增加有关（bs≤-.09，p<.049）。还发现了父母报告的夜间睡眠时间与愤怒之间的双向关联——晚上愤怒增加与夜间睡眠时间减少有关，睡眠时间减少与早晨愤怒增加有关（bs≤-.17，p<.019）。特质易激惹调节了这种关联，对于更易怒的青少年来说，这种关联更强（b=-.03，p<.027）。
本研究增加了文献，并提出了睡眠-易激惹动态作为潜在的治疗靶点。
