We sought to characterize relationships between sluggish cognitive tempo (SCT) and both internalizing symptoms and executive functioning in adults with ADHD.
A total of 102 adults with ADHD completed clinical interviews and clinical rating scales. Hierarchical regression analyses were conducted to ascertain the independent predictive power of SCT symptoms for deficits in executive function (EF) after considering severity of ADHD inattentive and hyperactive-impulsive symptoms and internalizing symptoms.
SCT correlated with ADHD inattentive symptoms and dimensional measures of depression and anxiety but not with clinical diagnosis of depression or anxiety. SCT predicted EF deficits over and above the effects of internalizing and ADHD symptoms. This relationship between SCT and EF was limited to the subset of participants ( n = 48) receiving stimulant treatment.
SCT in adults with ADHD is associated with internalizing symptoms, ADHD inattentive symptoms, and, independently, with EF deficits. Further research is needed to ascertain why this relationship occurred primarily in adults concurrently receiving stimulants.
我们试图描述成人注意力缺陷多动障碍（ADHD）患者中迟缓认知节奏（SCT）与内化症状及执行功能之间的关系。
共有102名成人ADHD患者完成了临床访谈和临床评定量表。在考虑ADHD注意力不集中、多动冲动症状的严重程度以及内化症状后，进行分层回归分析，以确定SCT症状对执行功能（EF）缺陷的独立预测能力。
SCT与ADHD注意力不集中症状以及抑郁和焦虑的维度测量相关，但与抑郁或焦虑的临床诊断无关。SCT在考虑内化症状和ADHD症状的影响之外，还能预测EF缺陷。SCT与EF之间的这种关系仅限于接受兴奋剂治疗的参与者子集（n = 48）。
成人ADHD患者的SCT与内化症状、ADHD注意力不集中症状相关，并且独立地与EF缺陷相关。需要进一步研究以确定为何这种关系主要发生在同时接受兴奋剂治疗的成人中。
