Few studies have examined whether separate dimensions of Sluggish Cognitive Tempo (SCT)-inconsistent alertness and slowness-have different external correlates from each other as well as symptoms of ADHD inattention (ADHD-IN).
Participants were 131 Spanish children (ages 6-16; 72% boys) diagnosed with ADHD.
In regression analyses, ADHD-IN was positively associated with hyperactivity/impulsivity, conduct problems, defiance/aggression, anxiety, peer relations problems, and learning problems. SCT-inconsistent alertness was positively associated with hyperactivity/impulsivity and peer relations problems. In contrast, SCT-slowness was negatively associated with hyperactivity/impulsivity and conduct problems and positively associated with depression and learning problems. Results were consistent after controlling for depression, medication status, and sex.
The findings support SCT to be a construct with two dimensions that have unique correlates relative to each other as well as ADHD-IN. Future research on SCT should separate these dimensions of SCT to provide a better understanding of the construct.
很少有研究探讨认知迟缓节奏（SCT）的不同维度——警觉性不一致和反应迟缓——是否与彼此以及注意力缺陷多动障碍（ADHD）注意力不集中症状（ADHD-IN）有不同的外部关联。
研究对象为131名被诊断患有ADHD的西班牙儿童（年龄6 - 16岁；72%为男孩）。
在回归分析中，ADHD-IN与多动/冲动、品行问题、违抗/攻击、焦虑、同伴关系问题和学习问题呈正相关。SCT警觉性不一致与多动/冲动和同伴关系问题呈正相关。相比之下，SCT反应迟缓与多动/冲动和品行问题呈负相关，与抑郁和学习问题呈正相关。在控制了抑郁、用药情况和性别后，结果依然一致。
研究结果支持SCT是一个具有两个维度的结构，这两个维度相对于彼此以及ADHD-IN都有独特的关联。未来关于SCT的研究应将SCT的这些维度区分开来，以便更好地理解这一结构。
