为了测试缓慢的认知克里思（SCT）和DSM-IV ADHD症状之间的关系，父母和教师的18个DSM-IV ADHD项目和5个潜在的SCT项目的评级，获得了在社区样本的8-18岁的双胞胎，是过度选择ADHD和学习障碍（n = 296）。验证性因素分析显示，三因素模型提供了最好的拟合家长和教师的评级数据。DSM-IV注意力不集中和多动-冲动症状加载在两个因素上，与DSM-IV模型一致，五个SCT症状主要加载在第三个因素上。SCT和注意力不集中因素高度相关，而SCT和多动-冲动性弱相关。两名评分员均表明，符合症状标准的儿童的组合和注意力不集中的亚型表现出显着更多的SCT症状比那些符合症状标准的多动-冲动型和对照组没有ADHD。根据教师评分，满足不注意类型症状标准的儿童比满足组合类型标准的儿童表现出更多的SCT症状。这些结果表明，SCT是一个内部一致的结构，与DSM-IV注意力不集中显着相关。
To test the relation between sluggish cognitive tempo (SCT) and DSM-IV ADHD symptoms, parent and teacher ratings of the 18 DSM-IV ADHD items and five potential SCT items were obtained in a community sample of 8-18 year-old twins that was overselected for ADHD and learning disabilities ( n = 296). Confirmatory factor analyses revealed that a three-factor model provided the best fit to the data for both parent and teacher ratings. DSM-IV inattention and hyperactivity-impulsivity symptoms loaded on two factors consistent with the DSM-IV model, and five SCT symptoms loaded primarily on a third factor. The SCT and inattention factors were highly correlated, whereas SCT and hyperactivity-impulsivity were weakly related. Both raters indicated that children meeting symptom criteria for the combined and inattentive subtypes exhibited significantly more SCT symptoms than those meeting symptom criteria for hyperactive-impulsive type and the comparison group without ADHD. Children meeting symptom criteria for the inattentive type exhibited significantly more SCT symptoms than those meeting criteria for the combined type, based on teacher ratings. These results suggest that SCT is an internally consistent construct that is significantly associated with DSM-IV inattention.
