Sleep problems are prevalent in children with neurodevelopmental disabilities and are associated with the expression of restricted and repetitive behaviors (RRBs). Children (n = 57) with autism spectrum disorder (ASD, n = 38) or developmental delay (DD, n = 19) participated in multiple assessments of intellectual ability, ASD symptoms, and RRBs (3 timepoints for ASD, 2 for DD). Sleep problems assessed at age 4 via parent report were associated with trajectories of higher-order RRBs (sameness/ritualistic/compulsive behaviors) from age 2-6 in the ASD group, and from age 2-4 in the DD group, even after controlling for intellectual ability, social-affective symptoms, and anxiety. Trajectories of stereotyped/restricted behaviors were unrelated to sleep problems. Sleep problems were associated with trajectories of higher-order (but not lower-order) RRBs in a transdiagnostic sample.
睡眠问题在患有神经发育障碍的儿童中很常见,并且与受限和重复行为(RRBs)的表达有关。自闭症谱系障碍(ASD,n=38)或发育迟缓(DD,n=19)的儿童(n=57)参与了多次智力能力、ASD 症状和 RRBs 的评估(ASD 有 3 个时间点,DD 有 2 个时间点)。通过家长报告在 4 岁时评估的睡眠问题与 ASD 组从 2 岁到 6 岁、DD 组从 2 岁到 4 岁的高阶 RRBs(同一性/仪式性/强迫性行为)轨迹相关,即使在控制了智力能力、社会情感症状和焦虑之后也是如此。刻板/受限行为的轨迹与睡眠问题无关。在跨诊断样本中,睡眠问题与高阶(而非低阶)RRBs 的轨迹相关。
