本研究采用韦氏儿童智力量表（韦氏儿童智力量表- iv）对患有注意缺陷/多动障碍（ADHD）和/或发育协调障碍（DCD）儿童的认知表现进行了探讨。参与者是62名年龄在9岁8个月到12岁7个月之间的儿童。这些儿童被分为四组：比较组（n = 26）、ADHD组（n = 14）、DCD组（n = 11）和ADHD + DCD组（n = 11）。使用澳大利亚破坏性行为量表评估ADHD症状，使用麦卡伦神经肌肉发育评估（MAND）评估运动能力。DCD组和ADHD + DCD组的知觉推理能力明显较差，ADHD组无明显差异。这些发现提供了证据，表明视觉空间能力的缺陷可能是DCD的基础，而不是ADHD。这些发现揭示了ADHD和/或DCD的不同认知特征，因此目前的研究并不支持理解ADHD和DCD合并症基础的共同病因学假设。(C) 2011 Elsevier Ltd.版权所有。
This study explored the cognitive performance of children with Attention Deficit/Hyperactivity Disorder (ADHD) and/or Developmental Coordination Disorder (DCD) using the Wechsler Intelligence Scale for Children-IV. Participants were 62 children with ages between 9 years 8 months and 12 years 7 months. These children were placed into one of the four groups: Comparison (n = 26), ADHD (n = 14), DCD (n = 11), and ADHD + DCD (n = 11) groups. The ADHD symptoms were assessed using the Australian Disruptive Behaviours Scale, and motor ability was assessed using the McCarron Assessment of Neuromuscular Development (MAND). Significantly poorer perceptual reasoning ability was seen in DCD and ADHD + DCD groups but not in the ADHD group. The findings provide evidence that a deficit in visuo-spatial ability may underlie DCD but not ADHD. These findings revealed different cognitive profiles for ADHD and/or DCD, thus the current study does not lend support to the common aetiology hypothesis in understanding the basis of ADHD and DCD comorbidity.
