This study investigates the prospective associations between short sleep duration, insomnia symptoms, and psychotic-like experiences (PLEs) in a large sample of Chinese adolescents. This study utilized a three-timepoint repeated cross-sectional survey with two nested longitudinal subsamples. A total of 17,722 adolescents were assessed at baseline (April 21 to May 12, 2021) and six months later (December 17 to 26, 2021). Out of these, 15,694 adolescents provided complete responses to the questions at baseline and one year later (May 17 - June 6, 2022). A self-administered questionnaire was used to measure sample characteristics (at baseline), sleep duration, insomnia symptoms, and PLEs (at each assessment), and negative life events (at two follow-ups). Baseline short sleep duration and insomnia symptoms predicted frequent PLEs at both follow-up assessments. Additionally, baseline frequent PLEs also predicted insomnia symptoms at six months and one year later. However, when controlling for confounders, PLEs at baseline only predicted short sleep duration at six months, and not at one year. This study reveals bidirectional prospective relationships between short sleep duration, insomnia symptoms, and PLEs, even after controlling for covariates. Therefore, it is crucial to assess both sleep patterns and PLEs in order to promote optimal sleep and mental health among adolescents.
本研究调查了中国大量青少年样本中短睡眠时间、失眠症状与类精神病体验（PLEs）之间的前瞻性关联。本研究采用了一个包含两个嵌套纵向子样本的三次重复横断面调查。共有17722名青少年在基线期（2021年4月21日至5月12日）和六个月后（2021年12月17日至26日）接受了评估。其中，15694名青少年在基线期和一年后（2022年5月17日至6月6日）对问题提供了完整答复。采用自填式问卷来测量样本特征（在基线期）、睡眠时间、失眠症状和类精神病体验（在每次评估时）以及负面生活事件（在两次随访时）。基线期的短睡眠时间和失眠症状在两次随访评估中均预测了频繁的类精神病体验。此外，基线期频繁的类精神病体验在六个月和一年后也预测了失眠症状。然而，在控制混杂因素后，基线期的类精神病体验仅在六个月时预测了短睡眠时间，而在一年时则未预测。本研究揭示了短睡眠时间、失眠症状和类精神病体验之间的双向前瞻性关系，即使在控制协变量之后也是如此。因此，为了促进青少年的最佳睡眠和心理健康，评估睡眠模式和类精神病体验都至关重要。
