Abstract: Objective To study the clinical profiles and co-morbidities of children with sub-clinical attention deficit hyperactivity disorder (ADHD) and to explore the necessity of intervention to these children. Methods 101 children with sub-clinical ADHD and 131 children with ADHD were examined by the China-Wechsler Intelligence Scale for Children(C-WISC)and Vanderbilt ADHD Assessment Scale,the outcomes were analyzed and compared with those from normal children. Results The average verbal intelligence quotient(VIQ),performance intelligence quotient(PIQ)and full intelligence quotient(FIQ) of ADHD group were 93.40±14.74,92.70±13.93 and 92.46±14.21 respectively;The average VIQ,PIQ and FIQ of sub-clinical ADHD group were 97.03±12.28,95.44±11.97 and 95.97±10.78 respectively.There were no statistically significant differences between these two group in VIQ,PIQ and FIQ(P＞0.01).The average scores of ADHD group,sub-clinical group and normal children group on attention deficit factor were 2.06±1.57,1.57±0.39 and 0.91±0.51 respectively,and those in hyperactivity and impulsion factor were 1.75±0.59,1.23±0.51 and 0.68±0.48 respectively.There were statistically significant difference between these three group in both attention deficit factor and hyperactivity and compulsion factor(P＜0.01).The average score of these three groups on function were 2.90±0.60,2.65±0.54 and 2.06±0.51 respectively.There was also statistically significant difference between these three group in score on function(P＜0.01).There was no statistically significant difference among ADHD group and sub-clinical group in distribution of common co-morbidities(P＞0.01). Conclusion Although sub-clinical ADHD children don't meet full of the ADHD criteria,it is still necessarily for them to have appropriate intervention and screening of common co-morbidities.
