目的 通过年龄、性别等多方面研究各亚型注意缺陷多动障碍（ADHD）儿童的智力结构分布特征的临床研究，为ADHD的个体化干预提供科学依据。方法 实验组纳入ADHD儿童754例，其中注意缺陷型（ADHD-I）280例（37.13%）、多动-冲动型（ADHD-HI）212例（28.12%）、混合型（ADHD-C）262例（34.75%），按年龄分为三组：低龄组（6~8岁）、中龄组（9~11岁）及高龄组（12~14岁）；对照组为正常儿童412例，为同期选择的性别、年龄相匹配的儿童。选择采用韦氏智力评估等方法分别对两组儿童进行评估等，对评估结果进行比较和综合分析。结果 ADHD儿童的智力评估结果低于对照组（P＜0.01），且在言语智商方面表现更为明显，在各分测验中以A因子（言语理解）和C因子（记忆/注意集中）为主，而B因子（知觉组织能力）方面则无差异。ADHD-HI型及ADHD-C型的总智商及操作智商均高于ADHD-I型，ADHD-C型言语智商和A因子均高于ADHD-I型（P＜0.01），ADHD-HI型的智力水平最高，而ADHD-I型与ADHD-C型的智力水平差异无统计学意义（P＞0.05）。各年龄段ADHD儿童的智力发育均受到不同程度的影响，尤其是中龄组儿童及高龄组女童所受影响更明显；低、中龄组儿童的智力发育水平均高于高龄组儿童，提示ADHD儿童的智力损害随年龄增长而加重；同一年龄段ADHD女童的智力损害较男童更为严重。结论 本地区6~14岁ADHD儿童的智力水平较低，以言语智商低下更为明显，ADHD-HI型在3个亚型中智力损害最小，ADHD儿童的智力损害随年龄增长而加重，同一年龄段ADHD女童的智力损害较男童更为严重。

   Objective To investigate the distribution characteristics of intellectual structure in children with different subtypes of attention deficit hyperactivity disorder（ADHD）by age and gender，providing scientific basis for individualized treatment and intervention of ADHD．Methods The experimental group consisted of 754 children with ADHD，including 280 cases（37.13%）of inattentive type（ADHD-I），212 cases（28.12%）of hyperactivity impulsive type（ADHD-HI），and 262 cases（34.75%）of combined type（ADHD-C）．They were divided into three groups by age：young group（6-8 years old），middle group（9-11 years old），and older group（12-14 years old）．The control group consisted of 412 normal children with matched sex and age recruited during the same period and had similar sex ratio．The specific methods of Wechsler Intelligence Scale were mainly applied to evaluate normal children and children with ADHD，and the evaluation results were subjected to multidimensional analysis and comparison．Results The intelligence assessment results of ADHD children were significantly lower than those of the control group（P＜0.01），with a more pronounced performance in verbal intelligence．In various sub tests，factors A（verbal comprehension）and C（memory and attention concentration）were the main factors，while there was no difference in factor B（perceptual organization ability）．The ADHD-HI and ADHD-C types had higher total intelligence and operational intelligence than the ADHD-I type，and the ADHD-C type had higher verbal intelligence and factor A than the ADHD-I type（P＜0.01）．The intelligence level of the ADHD-HI type is the highest，while there is no statistically significant difference in intelligence level between the ADHD-I type and the ADHD-C type．The intellectual development of children in different age groups was affected to varying degrees，especially in the middle and older groups of girls．This study found that the intellectual development of children in the young and middle group was higher than that of children in the older group，indicating that the intellectual development of ADHD children will be increasingly damaged with age．At the same time，it was also found that ADHD girls in the same age group had more severe intellectual development impairment than boys．Conclusions The intelligence level of children with ADHD aged 6-14 in this region is relatively low，with verbal intelligence quotient being more pronounced．ADHD-HI has the smallest intellectual impairment among the three subtypes，and the intellectual development of ADHD children becomes more severe with age．ADHD girls in the same age group have more severe intellectual development impairment than boys．
