The objective of this study was to investigate potential relationships between two measures of sleep impairments (i.e., sleep duration and sleep efficiency [SE]) and attention and executive functioning in children with attention-deficit/hyperactivity disorder (ADHD). Parents of 43 children (mean age = 10 ± 1.8 years) with ADHD completed sleep and behavioral questionnaires. Children also wore a wrist actigraph for seven nights and were subsequently assessed with the Conners' continuous performance test (CPT)-2. A significant relationship was found between lower SE and increased variability in reaction time on the CPT. Shorter sleep duration was associated with a range of executive functioning problems as reported by the parents. The relationships between sleep duration and the executive functioning measures held even after controlling for age, gender, and use of medication, but not the relationships with SE. These results suggest that sleep quantity is an important correlate of executive functioning in children with ADHD.
本研究旨在探讨两种睡眠障碍测量指标(即睡眠时间和睡眠效率[SE])与注意缺陷多动障碍(ADHD)儿童的注意力和执行功能之间的潜在关系。43 名儿童(平均年龄= 10±1.8 岁)的家长完成了睡眠和行为问卷。儿童还佩戴了腕部活动记录仪七个晚上,随后使用康纳斯连续操作测试(CPT)-2 进行评估。研究发现,SE 较低与 CPT 中反应时间的变异性增加之间存在显著关系。睡眠时间较短与父母报告的一系列执行功能问题相关。即使在控制年龄、性别和药物使用的情况下,睡眠时间与执行功能测量之间的关系仍然存在,但与 SE 的关系则不存在。这些结果表明,睡眠量是 ADHD 儿童执行功能的一个重要相关因素。
