To test whether the adult self-report scale for ADHD, six-items version (ASRS-6), measures inattentiveness and hyperactivity independently.
The ASRS-6 was completed by 234 university students and 157 outpatients treated for drug dependence. In both samples, the ASRS-6 was subjected to two confirmatory factor analyses, one testing a one-factor model and the other testing a model with two correlated factors indicating inattentiveness and hyperactivity, respectively. Test-retest reliability of the subscales was tested on a subset of the student sample (n = 25).
In both samples, the one-factor solution did not fit the data, but the two-factor solution fit the data better. Subscales differed in their correlates in ways that mirror the correlates of inattentiveness and hyperactivity in the published literature on ADHD. In the student sample, the test-retest reliability was adequate for hyperactivity (r = .70) and inattentiveness (r = .77).
The ASRS-6 measures two correlated constructs, rather than one unitary construct.
检验成人注意缺陷多动障碍自评量表 6 项版本（ASRS-6）是否能分别测量注意力不集中和多动。
234 名大学生和 157 名药物依赖门诊患者完成了 ASRS-6。在两个样本中，ASRS-6 均进行了两次验证性因素分析，一次检验单因素模型，另一次检验分别表示注意力不集中和多动的两个相关因素的模型。学生样本中的一个子样本（n = 25）测试了亚量表的重测信度。
在两个样本中，单因素模型均不能拟合数据，而双因素模型拟合得更好。亚量表的相关指标与 ADHD 文献中注意力不集中和多动的相关指标一致。在学生样本中，多动（r =.70）和注意力不集中（r =.77）的重测信度足够。
ASRS-6 测量两个相关的结构，而不是一个单一的整体结构。
