迟缓的认知节奏（SCT）症状对儿童样本的精神和功能结果有独特的影响；然而，SCT测量在成年门诊患者中的心理测量特性尚不清楚。以注意缺陷/多动障碍（ADHD）评估的成人（n=124）提供了SCT症状的自我和附带报告。SCT量表具有良好的内部一致性，并在评分者中产生三个因素：缓慢/白日梦，困倦/懒散，低启动/持续。SCT评分在评分者中表现出ADHD症状的收敛效度。通过附带报告，ADHD患者的SCT评分高于无ADHD患者，当考虑合并症时，这种模式相似。在考虑ADHD症状后，SCT与较差的功能相关，根据报告来源有一些不同的影响。研究结果支持三因素SCT量表在成人门诊患者中的内部一致性和有效性。自我报告和间接报告之间的差异结果证明了临床环境中多重报告SCT的重要性。
Sluggish Cognitive Tempo (SCT) symptoms uniquely contribute to psychiatric and functional outcomes in child samples; however, the psychometric properties of SCT measures among adult outpatients are unknown. Adults (n=124) presenting for an attention-deficit/hyperactivity disorder (ADHD) evaluation provided self- and collateral report of SCT symptoms. The SCT scale had good internal consistency and yielded three factors across raters: Slow/Daydreamy, Sleepy/Sluggish, and Low Initiation/Persistence. SCT scores exhibited convergent validity with ADHD symptoms across raters. Individuals with ADHD received higher SCT ratings than those without ADHD via collateral report, a pattern that was similar when comorbidity was considered. SCT was associated with poorer functioning after accounting for ADHD symptoms with some differential effects based on reporting source. Findings support the internal consistency and validity of a three-factor SCT scale among adult outpatients. Differential results between self- and collateral report demonstrate the importance of multiple reporters of SCT in clinical settings.
