DSM-IV-TR将ADHD-主要注意力不集中定义为允许多达五种多动/冲动症状，而注意力不集中类型的理论通常假设一组活动减退，并以处理速度和认知干扰缺陷为特征。在社区招募的572名儿童和青少年样本中，ADHD（ADD）的纯注意力不集中亚型被定义为符合DSM-IV-TR ADHD-PI标准但有两个或两个以下多动/冲动症状的人。将ADD患者的处理和输出速度与DSM-IV-TR ADHD合并类型和非ADHD对照组进行比较。然后将这些结果与DSM-IV-TR定义的ADHD-PI与ADHD-C和对照组进行比较。加工和输出速度用Trailmaking A和B以及Stroop测验进行评估。认知干扰控制与Stroop任务的干扰得分进行了评估。在ADD与ADHD-C和对照组的比较中发现认知干扰速度较慢，但在ADHD-PI与ADHD-C和对照组的比较中没有发现。在输出速度测量方面，ADD表现出最慢的性能，与对照组显着不同，并且设定换档速度对比（Trailmaking B）对比的效应大小是ADHD-PI与对照组比较的两倍。由DSM-IV-TR定义的ADHD-注意力不集中型是一种异质性疾病，受影响的患者中有一定比例几乎没有表现出多动/冲动症状。这个亚组可能代表一种独特的注意力不集中的状况，其特征在于认知干扰控制差和处理或输出速度慢。
DSM-IV-TR defines ADHD-Predominantly Inattentive as allowing up to five symptoms of hyperactivity/impulsivity, while theories of the inattentive type usually assume a group that is hypoactive and characterized by processing speed and cognitive interference deficits. In a community-recruited sample of 572 children and adolescents, a pure inattentive subtype of ADHD (ADD) was defined as those who met DSM-IV-TR criteria for ADHD-PI but had two or fewer hyperactive/impulsive symptoms. Processing and output speeds of those with ADD were compared to those identified with DSM-IV-TR ADHD combined type and non-ADHD controls. These results were then contrasted with those found when DSM-IV-TR defined ADHD-PI was compared with ADHD-C and controls. Processing and output speed were assessed with the Trailmaking A and B and the Stroop Naming Tests. Cognitive interference control was assessed with the interference score from the Stroop Task. Slower cognitive interference speed was found in the ADD vs. ADHD-C and controls comparisons, but not the ADHD-PI versus ADHD-C and controls comparisons. On output speed measures, ADD exhibited the slowest performance, significantly different from controls and the effect size for the set-shifting speed contrast (Trailmaking B) contrast was double that of the ADHD-PI vs. control comparison. ADHD-Inattentive type as defined by the DSM-IV-TR is a heterogeneous condition with a meaningful proportion of those affected exhibiting virtually no hyperactive/impulsive symptoms. This subgroup may represent a distinct inattentive condition characterized by poor cognitive interference control and slow processing or output speed.
