Research has identified a relationship between sluggish cognitive tempo (SCT) symptoms and symptoms of ADHD, anxiety, and depression; however, no study has controlled for symptoms of ADHD, anxiety, and depression when examining impairment related to SCT symptoms. This study aimed to examine (a) the extent to which functional impairment and executive function (EF) problems were accounted for by SCT symptoms when controlling for ADHD, anxiety, and depression symptoms, and (b) which type of symptoms were associated with the greatest amount of impairment.
College students ( N = 458) completed self-report scales of ADHD, SCT, anxiety, and depression symptoms, as well as functional impairment and EF problems.
Thirteen percent of the sample was found to have high levels of SCT symptoms. SCT symptoms showed a moderate to strong correlation with the other symptom sets; however, high levels of SCT symptoms often occurred separate from high levels of ADHD, anxiety, or depression symptoms. SCT symptoms accounted for the most unique variance for both EF problems and functional impairment. Students with high levels of SCT symptoms, with or without high levels of ADHD symptoms, exhibited more impairment and EF problems than the controls.
SCT is a clinical construct worthy of additional study, particularly among college students.
研究已确定认知迟缓节奏（SCT）症状与注意力缺陷多动障碍（ADHD）、焦虑症和抑郁症症状之间存在关联；然而，在研究与SCT症状相关的损害时，尚无研究对ADHD、焦虑症和抑郁症的症状进行控制。本研究旨在探讨：（a）在控制ADHD、焦虑症和抑郁症症状时，SCT症状在多大程度上导致了功能损害和执行功能（EF）问题；（b）哪种类型的症状与最大程度的损害相关。
大学生（N = 458）完成了关于ADHD、SCT、焦虑症和抑郁症症状的自我报告量表，以及功能损害和EF问题的量表。
发现13%的样本具有高水平的SCT症状。SCT症状与其他症状组呈现中度到强的相关性；然而，高水平的SCT症状常常独立于高水平的ADHD、焦虑症或抑郁症症状出现。SCT症状在EF问题和功能损害方面解释了最多的独特方差。具有高水平SCT症状的学生，无论是否伴有高水平的ADHD症状，都比对照组表现出更多的损害和EF问题。
SCT是一个值得进一步研究的临床概念，尤其是在大学生群体中。
