研究支持认知节奏迟缓（SCT）（例如精神混乱和行为/思维迟缓）与其他精神病理学的区别。然而，SCT 与睡眠功能之间的关系尚未得到充分研究。我们对 325 名 6-10 岁儿童（62% 为男性）进行了 SCT 与睡眠功能之间的关联研究，这些儿童被转至一家经认可的肺部睡眠障碍中心。检查了护理人员对 SCT 的评分、其他精神病理学（即注意力不集中/多动、对立、抑郁、焦虑）、睡眠功能（行为和器质性症状）以及睡眠障碍诊断之间的相关性。使用回归评估了 SCT 和其他精神病理学对控制儿童人口统计数据的睡眠问题严重程度的独特影响。还进行了回归分析，以检验 SCT 对损伤（即学业困难、养育压力和其他精神病理学）的独特影响，并控制儿童人口统计、睡眠问题严重程度和其他精神病理学症状。 SCT 与大多数睡眠测量值呈弱至中度相关（rs = .07-.39），与日间嗜睡测量值呈中度至强相关（rs = .33 和 .53）。在回归分析中，SCT 与睡眠功能严重程度增加和学业功能受损具有独特的相关性。 SCT 还与较高水平的抑郁和注意力不集中/多动有关，但与焦虑无关，并且与对立性呈负相关。最后，SCT 症状与更大的亲子互动功能障碍有着独特的相关性。研究结果表明，SCT 与睡眠问题和白天嗜睡有关，但并非多余。此外，在控制临床相关变量后，SCT 仍然与睡眠障碍儿童的多个功能障碍相关，这凸显了评估有睡眠问题的儿童的 SCT 症状的潜在价值。 (C) 2016 Elsevier Ltd. 保留所有权利。
Research supports the distinctness of sluggish cognitive tempo (SCT) (e.g., mental confusion and slowed behavior/thinking) from other psychopathologies. However, the relation between SCT and sleep functioning has not been adequately studied. We examined the association between SCT and sleep functioning in 325 children (62% male) ages 6-10 years referred to a pulmonary-based, accredited Sleep Disorders Center. Correlations between caregiver ratings of SCT, other psychopathologies (i.e., inattention/hyperactivity, oppositionality, depression, anxiety), sleep functioning (both behavioral and organic symptoms), as well as sleep disorder diagnoses, were examined. Unique effects of SCT and other psychopathologies on sleep problem severity controlling for child demographics were assessed using regressions. Regression analyses were also conducted to examine the unique effects of SCT on impairment (i.e., academic difficulties, parenting stress, and other psychopathologies) controlling for child demographics, sleep problem severity, and other psychopathology symptoms. SCT was weakly to moderately correlated with most measures of sleep (rs = .07-.39) and moderately to strongly correlated with measures of daytime sleepiness (rs = .33 and .53). In the regression analyses, SCT was uniquely associated with greater sleep functioning severity and impairment in academic functioning. SCT was also uniquely associated with higher levels of depression and inattention/hyperactivity, but not anxiety, and negatively associated with oppositionality. Finally, SCT symptoms were uniquely associated with greater parent-child dysfunctional interaction. Findings demonstrate that SCT is related to, but not redundant with, sleep problems and daytime sleepiness specifically. Further, SCT remained associated with several domains of functional impairment in sleep-disordered children after controlling for clinically-relevant variables, highlighting the potential value in assessing SCT symptoms in children with sleep problems.
