Sluggish cognitive tempo (SCT) refers to a set of symptoms that prior research has found to be related to several different psychological disorders, especially the predominantly inattentive presentation of ADHD. This study collected evidence relevant to the question of whether SCT is a distinct disorder. College students ( = 910) completed measures of SCT, ADHD, depression, anxiety, sleep quality, and substance misuse. Students reporting clinically high SCT (reporting at least five symptoms often or very often) had significantly higher levels and rates of other types of psychopathology. Moreover, when students reporting clinically significant levels of ADHD, depression, and anxiety symptoms, poor sleep quality, or hazardous levels of alcohol or cannabis use were removed, very few students reporting high SCT remained (only 4.8% of the original high-SCT group). SCT may be best thought of as a symptom set common to many types of psychopathology, and it may be caused by sleep problems or substance misuse as well.
迟钝的认知节奏（SCT）是一组症状，先前的研究发现与几种不同的心理障碍有关，尤其是 ADHD 的主要注意力不集中表现。本研究收集了与 SCT 是否为一种独特障碍相关问题的证据。大学生（=910）完成了 SCT、ADHD、抑郁、焦虑、睡眠质量和物质滥用的测量。报告临床高 SCT（报告至少有五种症状经常或非常频繁）的学生具有显著更高水平和更高比例的其他类型的精神病理学。此外，当去除报告 ADHD、抑郁和焦虑症状、睡眠质量差或酒精或大麻使用危险水平的学生后，报告高 SCT 的学生人数非常少（仅为原始高 SCT 组的 4.8%）。SCT 可能最好被视为许多精神病理学共有的一组症状，它可能是由睡眠问题或物质滥用引起的。
