“迟缓的认知克里思”（SCT）是一种假设用来描述一系列行为的结构，包括白日梦、嗜睡、困倦、难以维持注意力和活动不足。虽然该结构的定义不一致，但SCT的测量结果显示与注意力缺陷/多动障碍（ADHD）的症状，特别是注意力不集中有关。因此，更好地表征SCT症状可能有助于更好地预测ADHD儿童的功能困难的特定区域。本研究检查了最近开发的14项SCT量表的心理测量学特征（Penny等人，Psychological Assessment 21：380-389，2009），由教师对转诊进行门诊神经心理学评估的儿童完成。探索性因素分析确定了临床样本中的三个因素：睡眠/睡眠不足，缓慢/白日梦，低启动/持久性。此外，SCT症状，特别是那些加载在睡眠/懒惰和缓慢/白日梦的因素，与注意力不集中的相关性比与多动/冲动症状的相关性更强，而低启动/持续性症状增加了显著的独特差异（超过注意力不集中的症状），以预测学业进展障碍。
"Sluggish cognitive tempo" (SCT) is a construct hypothesized to describe a constellation of behaviors that includes daydreaming, lethargy, drowsiness, difficulty sustaining attention, and underactivity. Although the construct has been inconsistently defined, measures of SCT have shown associations with symptoms of attention-deficit/hyperactivity disorder (ADHD), particularly inattention. Thus, better characterization of SCT symptoms may help to better predict specific areas of functional difficulty in children with ADHD. The present study examined psychometric characteristics of a recently developed 14-item scale of SCT (Penny et al., Psychological Assessment 21:380-389, 2009), completed by teachers on children referred for outpatient neuropsychological assessment. Exploratory factor analysis identified three factors in the clinical sample: Sleepy/Sluggish, Slow/Daydreamy, and Low Initiation/Persistence. Additionally, SCT symptoms, especially those loading on the Sleepy/Sluggish and Slow/Daydreamy factors, correlated more strongly with inattentive than with hyperactive/impulsive symptoms, while Low Initiation/Persistence symptoms added significant unique variance (over and above symptoms of inattention) to the predictions of impairment in academic progress.
