Methods:In the city of Changsha, 465 normal children aged 8～12 in two primary schools and 27 ADHD children in an outpatient department were tested with WWPARS. Psychometric properties of the scale were analyzed for reliability and validity. Results: While levels of activity increased with age for all children, there was no significant difference between the two groups assessed. The scale attained good reliability and validity. Conclusion: This scale can be applied for evaluation of activity levels for Chinese children.

Objective:To explore the clinical features of subtyp es of ADHD in DSM-Ⅳ.Method:126 children fulfilled ADHD criteria of D S M-Ⅳ were further divided into 3 subtypes:predominantly inattentive(PI,61 cases) , predominantly hyperactive-impulsive(HI,9 cases)and combined type(CT,56 cases).C om orbid mental disorders were compared among the three groups.Parents and teacher s of children in each group completed CBCL(child behavior checklist)and TRF(teach er's report form).CWISC(Wechsler intelligence scale for children,Chinese versio n )and attention tests were also applied in each group.Results:Childr e n in CT group had more conduct disorder,more externalizing,delinquent and aggres sive behaviors rating by parents and teachers,and more inattentive than children in PI group.School performance of children in PI group was better than that of the other two groups evaluated by teachers.Conclusion:ADHD CT subty pe had highest rate of comorbid conduct disorder.They have more externalizing b ehavior,more academic problems and more inattentive.This subtype may be the mos t impaired subtype.

Objective: To develop the norm of Piers-Harris Children's Self-concept Scale (PHCSS) in Chinese urban children and test the reliability and validity. Method: A total of 1698 children with the mean age 12?3 year-old (846 boys and 852 girls) from 20 cities in China completed the scale. Results: The test-retest reliability, split-half and Crobach were in 0.695～0.858, the correlation between each item score and total score were in 0.078～0.467, showed better item differentiation except for 3 items. The validity was perfect, represented by significant correlation (r=0.051～0.353) between the score and Conners Parent Symptom Questionnaire and Teacher Rating Scale. Conclusion: The results demonstrate the scale are suitable for demands of psychometrics and applicable in Chinese children.

Objective: To investigate the cerebral cognitive function and intelligence in children with learning disorder (LD). Method:Thirty children with LD were examined with Wisconsin Card Sorting Test (WCST) and the Wechsler intelligence Scale for Children-Chinese Revised (WISC-CR). The results were then compared between LD and healthy control.Results:Compared with healthy control, the correct categories of WCST and correct responses in LD group were significantly lower (4.3?1.3/5.1?1.2). The persistent errors (38.6?10.7/23.9?8.4), total trials and total errors of WCST in LD were significantly higher than those in healthy control. In LD group, the full intelligence quotient (FIQ)(89.0?14.3/112.6?17.0) and the verbal intelligence quotient (VIQ) and performance intelligence quotient (PIQ) of WISC were all significantly lower than those in healthy control. So did scores of four factors of WISC, such as arithmetic, comprehension, and block design and object assembly. The incidence of abnormal intelligence structure in LD (80%) was significantly higher than that in healthy control (30%). The IQ in LD children was positively correlated with the correct categories and correct responses of WCST, and negatively with the total trials and the total errors and persistent errors of WCST.Conclusion:LD children suffered the frontal executive function deficits and cognitive dysfunction.

ACKGROUND:Autism is a kind of neurobiological disease.The increase of plasma concentration of 5 hydroxytryptamine(5 HT) is considered to be one of study results,which is the most definite and has the best repetition,for the biological investigation of autism. Whether the season of birth and maternal mood during pregnancy are correlated with the occurrence of autism? OBJECTIVE:To compare the differences of the plasma concentration of 5 HT,season of birth and the maternal mood during pregnancy between autistic and normal children,and probe into the cause of increased 5 HT in autism. DESIGN:An observational comparative study taking autistic and normal children as the subjects. SETTINGS:A clinical psychological department of a university hospital;Mental Health Institute of the Xiangya Second Hospital;A rehabilitation center for dumb children of city grade. PARTICIPANTS:Children in the autistic group(n=54),who were in accordance with the diagnostic criteria of autism in Diagnostic and Statistical Manual of Mental Disorders Fourth Edition(DSM IV) and had the total score of social adaptive ability scale(SAAS) over 40, were selected from the Outpatient Clinic for Children of the Mental Health Institute,Xiangya Second Hospital of Central South University and the training class of autism of Shenzhen Special Education School;Children in the normal control group,who had no obvious somatic and neurological diseases,and developing delay detected by physical,neurological and mental status examinations, rough detection of developing level,were selected from the primary school and kindergarten in Changsha and Shenzhen cities. INTERVENTIONS:The plasma level of 5 HT was examined, season of birth and maternal mood during pregnancy were investigated in autistic and normal children.The children with autism were accessed with SAAS. MAIN OUTCOME MEASURES:The plasma level of 5 HT,the season of birth and the maternal mood during pregnancy in both groups. RESULTS:The score of SAAS in children with autism was 67.65± 1.67.The plasma level of 5 HT was(0.78± 0.32) μ mol/L in the autistic group,which was significantly higher than that in the normal control group [(0.62± 0.16) μ mol/L](t=3.17,P=0.002). There were 17 children with autism had increased 5 HT.Compare with normal children,most children with autism were born in winter and spring,and their mother had obvious mood problems during pregnancy. CONCLUSION:The 5 HT level is higher in children with autism than in normal children.Most children with autism were born in winter and spring,and their mother had obvious emotional problems during pregnancy.There are phase of high functioning of 5 HT in mother in key period of fetus cerebra development that may be one of the causes of hyperserotonemia in autism,and that is possibly one of the etiologies of autism.
