An international Sluggish Cognitive Tempo (SCT) Work Group proposed a new term for SCT, "cognitive disengagement syndrome," that more accurately describes the syndrome than does SCT. According to the Work Group, symptoms of SCT represent a cognitive dimension (cognitive disengagement) and a motor dimension (hypoactivity). Our study determined (1) if distinct factors representing cognitive disengagement and hypoactivity emerged when SCT items were factor analyzed and (2) the degree of differences in cognitive disengagement and hypoactivity within diagnostic groups. Mothers rated 1,177 children with autism, 725 with ADHD-Combined, and 307 with ADHD-Inattentive (4-17 years) and 665 elementary school children (6-12 years) on the Pediatric Behavior Scale (PBS). SCT prevalence rates were autism 32%, ADHD-Inattentive 27%, ADHD-Combined 18%, and elementary school students 7%. Factor analysis of the SCT items yielded two factors reflecting cognitive disengagement (in a fog/confused and stares/preoccupied/in own world) and hypoactivity (sluggish/slow moving/low energy, drowsy/sleepy/not alert, and tires easily) in all diagnostic groups. Cognitive disengagement prevalence rates and scores were significantly higher than hypoactivity in the autism and ADHD-C groups and in the autism and ADHD-C subgroups of children with SCT (but not in the ADHD-I and elementary school total groups and SCT subgroups). Our findings factor analyzing five SCT items support two SCT subfactors: cognitive disengagement and hypoactivity.
一个国际 Sluggish Cognitive Tempo (SCT) 工作组提出了一个新术语“认知脱离综合征”，该术语比 SCT 更准确地描述了这种综合征。根据工作组的说法，SCT 的症状代表了一个认知维度（认知脱离）和一个运动维度（活动减退）。我们的研究确定了：（1）当 SCT 项目进行因子分析时，是否出现了代表认知脱离和活动减退的不同因素；（2）在诊断组内，认知脱离和活动减退的差异程度。母亲们对 1177 名自闭症儿童、725 名 ADHD-混合型儿童、307 名 ADHD-注意力不集中型儿童（4-17 岁）和 665 名小学生（6-12 岁）进行了儿科行为量表（PBS）的评定。自闭症儿童的 SCT 患病率为 32%，ADHD-注意力不集中型儿童为 27%，ADHD-混合型儿童为 18%，小学生为 7%。对 SCT 项目进行因子分析后，在所有诊断组中均得出了两个反映认知脱离（昏昏欲睡/困惑和凝视/全神贯注/自我世界）和活动减退（行动迟缓/缓慢移动/能量低下，昏昏欲睡/困倦/不警觉，容易疲劳）的因素。在自闭症和 ADHD-C 组以及自闭症和 ADHD-C 亚组中，认知脱离的患病率和评分均显著高于活动减退（但在 ADHD-I 和小学生总组和 SCT 亚组中则不然）。我们的研究结果支持 SCT 有两个亚因素：认知脱离和活动减退。
