Objective：This study was designed to evaluate effects of methylphenidate(MPH) on event-related potentials(ERP) and continuous performance test(CPT) in attention-deficit hyperactivity disorder (ADHD) and to see the correlation between changes in ERP and changes in performance. Method：ERP and CPT were used to examine the acute effects of MPH(0.5mg/kg) in eleven ADHD boys(89-103 months old). Results：1) After MPH administration, P3 latency to nontarget stimuli at Fz was significantly decreased (p<0.01) and P2 amplitudes to target stimuli at Pz and at Oz and P3 amplitude to target stimuli at Cz were significantly increased(p<0.05). 2) Commission error and omission error in the CPT-X and commission error in the CPT-AX were decreased(p<0.01), and hits and perceptual sensitivity(d') in the CPT-X and d′ in the CPT-AX were increased(p<0.01). 3) The change of P3 latency to nontarget stimuli at Fz and the change of d′ in the CPT-X were negatively correlated(p<0.05), and the change of P2 amplitude to target stimuli at Pz and d′ in the CPT-AX were positively correlated(p<0.05). Conclusion：MPH improves change orienting reaction, the delivery of task relevant information, accuracy and perceptual sensitivity in ADHD. And the increase of ability to discriminate targets from non-targets reflects reduced evaluation time in large memory component task and enhanced change orienting reaction in simple task.

The effectiveness of behavior group counseling using the games of children with Attention Deficit Hyperactivity Disorder(ADHD) was studied with 24 primary school children (12 each in the experimental and in the control groups). The subjects were selected on the basis of the Abbreviated Conners Teacher Rating Scale-Revised. The counseling program consisted of 12 sessions over a 6-week period. Effectiveness of the training was evaluated with the Conners Teacher Rating Scale-Revised, the ADHD teacher's rating scale, and the Korea-Child Behavior Checklist. Findings were that the group receiving counseling exhibited improved attention, social relationships, and self control. They also exhibited decreased carelessness-passivity, hyperactivity, hostility and fewer behavior problems.

Objective : We investigated that ADHD categorical diagnosis and the dimensional tools for the evaluation of ADHD, widely used in the clinical field, such as the child behavior check list- Korean version (K-CBCL), Korean personality inventory for children (KPI-C), computerized Attention Diagnostic System (ADS). Method : The DSM-IV clinical diagnosis applied by child psychiatrist. K-CBCL, KPI-C, ADS are used. Ultimately, totally 161 ADHD children and 161 controls were evaluated. Subject group are consist of 202 boys (62.7%) and 120 girls (37.3%), and the mean age was $9.5{\pm}2.0$ years old. Results and Conclusion : Social problem, and attention problem in the K-CBCL, correct response time standard deviation in the computerized ADS were statistically significant different and attention problem in the K-CBCL, hyperactivity subscale in the KPI-C were significant trait, between subject group and control group. The ROC value of attention problem in the K-CBCL, hyperactivity subscale in the KPI-C, and ADS were .78, .93, .86. Finally, we found that K-CBCL, KPI-C, ADS were significant corelation with the ADHD categorical diagnosis.

Behavioral characteristics of Attention Deficit Hyperactivity Disorder (ADHD) are aften observed in normal children. As a result, it is at times difficult to distinguish behavior disorder of clinical significance and normal developmental phenomenon. In addition, symptoms of ADHD can vary greatly depending on situations and social context, creating considerable difficulties in assessment. Therefore it is important to obtain information from various sources and in diverse situations. It is also desirable to quantify the severity of the problems whenever possible and determine their clinical significance by comparing the data to developmental norms. Specifically, various assessment methods such as interview with parent and child, behavior rating scales, behavioral observation and psychological testing were reviewed with discussion on merits and limitatious of each. It was emphasized that systematic and comprehensive assessment utilizing appropriate methods is necessary for accurate diagnosis and treatment evaluation of ADHD.

Objectives : Attention-deficit hyperactivity disorder (ADHD) and Asperger's disorder (AD) in children are associated with attentional problems, impulsivity, hyperactivity, and difficulties with social interactions. Pharmacological treatment may alleviate symptoms of ADHD, but seldom solves difficulties with social interactions. Social skills training (SST) may assist in improving their social interactions. We examined the effects of SST on children's social competences, general behavior, and ADHD symptoms. Methods : Thirty four children, aged 7 to 12 years, participated in the cognitive behavioral SST program once a week at the outpatient division of child-adolescent psychiatry. SST was composed of 24 sessions (ninety minutes) for 6 months. Twenty-five children were diagnosed with ADHD, and 9 children were diagnosed with AD. Parents of the children rated Korea-Child Behavior Checklist (K-CBCL), Conner's rating scales, Korean-ADHD Rating Scale (K-ARS), Social Skill Rating System (SSRS), and Matson's Social Skill Rating Scale as an evaluation of the treatment effect, before the first session and after the final session of the training. Results : The ADHD group showed significantly increased scores of social and social competence of CBCL and SSRS. Further, scores of externalizing problems of CBCL, CRS, and ARS were significantly decreased. The Asperger's group showed significantly increased scores of social competence of CBCL, SSRS, and MESS. There was a significant difference of the improvement in CBCL's school and total behavior problem score, CRS between drug change group and no drug change group. Conclusion : The result of this study suggests that SST is effective in improving social skills for children with ADHD and AD. In addition, SST has shown its effectiveness in treating attentional problems for children with ADHD. To prove objective usefulness of SST, further studies with a more structured design and long-term duration along with a sufficient number of AD participants will be necessary.

Objectives : This study was conducted to examine whether there are qualitative differences in attention problem among children with various psychiatric disorders, including attention-deficit hyperactivity disorder (ADHD), depressive disorder, anxiety disorder, and tic disorder using clinical ADHD diagnostic system (ADS) T-scores. Methods : The subjects were 794 outpatient children aged from 5 to 15 years, including 540 children with ADHD, 95 children with depressive disorder, 86 children with anxiety disorder, and 73 children with tic disorder. Clinical T-scores on the ADS were calculated using the mean and standard deviations of four ADS variables for the ADHD group. Results : All four groups had T-scores on the ADS in the abnormal range. However, when comparing the clinical T-scores, the children with depressive and anxiety disorders performed better than the children with ADHD. We also found that although the four groups seemed to be similar in terms of clinical T-scores for omission and commission errors, there were significant differences in clinical T-scores for reaction time and the standard deviation of response time (RT) between the ADHD and other groups. Conclusions : We concluded that inattention and impulsivity might not be specific only to ADHD and that the clinical T-scores of RT and standard deviation of RT on the ADS could be used to discriminate between ADHD and other clinical groups.

Objective : The purpose is to analyze the effects of parent training interventions in reducing the symptoms of Attention Deficit Hyperactivity Disorder (ADHD) and to provide a basis for the effects. Methods : We collected literature published in international academic journals from 2009 to 2019 through ProQuest and Scopus databases. The search key terms were (ADHD OR Attention Deficit Hyperactivity Disorder) AND (Parent OR Mother OR Father) AND (Training OR Program OR Therapy OR Intervention) AND (Randomized OR Randomised OR Randomly). The PEDro scale was used to evaluate the quality of the studies, and a meta-analysis was conducted through Comprehensive Meta-Analysis 3.0. Results : Of 628 studies that we reviewed, 20 were eligible for inclusion. of parental training interventions for children with ADHD appeared close to a medium effect size while parent-child interventions (0.639) appeared to have a medium to large effect size. Oppositional defiant behavior and conduct disorder (0.737) in children and children's emotions (0.679) appeared close to a large effect size. ADHD symptoms hyperactivity and impulsivity (0.590) and child behavior (0.521) appeared to be over a medium effect size. We chose a random-effects model since heterogeneity tests showed significant results. Conclusion : We were able to confirm the effects of parent training interventions on the symptoms of children with ADHD. This will be used as evidence to provide a clinical basis for occupational therapists. More research related to parental training interventions should be carried out to ensure better reporting in the future.

The purpose of this study was to estimate the prevalence of ADHD based on estimation of ADHD rating scale between mother-teacher and teacher-teacher. In total, 491 mothers and 23 teachers rated 689 5-year-old children on the K-ADHDDS. Descriptive statistics, in addition to independent and paired samples t-test were performed. Overall, the percentages of children with ADHD on the rating scale were 3% in combined type, 7.1-8.6% in predominately hyperactive-impulsive type, and 4.2% in predominately inattentive type. Boys tended to show greater tendency of ADHD than girls’: Overall, ADHD tendency in boys was 1.3 times greater than girls. Specially, 2.3 times more for hyperactivity, 1.4 times more for impulsivity, and 3.4 more for inattention. The correlation between mothers’ and teachers’ ratings were .35 for total, .40 for hyperactivity, .24 for impulsivity, and .28 for inattention, and there were no significant differences. Alternatively teacher and teacher ratings were .71 for total, .70 for hyperactivity, .70 for impulsivity, and .67 for inattention, and there were significant differences in inattention subscale(p < .01).

Objectives : The aim of this study was to determine whether children with Tourette disorder (TD) have functional impairment and executive dysfunction in comparison to children with attention-deficit hyperactivity disorder (ADHD) and non-affected controls. Methods : From January 2006 to December 2013, 45 children and adolescents with TD and 50 children and adolescents with ADHD diagnosed at the Soonchunhyang University Bucheon Hospital and 50 non-affected controls were enrolled in this study. Functional impairment of the subjects was assessed using the Child and Adolescents Functioning Impairment Scale (CAFIS), parent and teacher versions. In addition, neuropsychological tests including Stroop color-word Test, Finger windows Test (FWT), and Digit span were administered. Outcomes were compared across the TD, ADHD, and non-affected controls. Results : No difference in CAFIS-parent and CAFIS-teacher results was observed between children with TD and non-affected controls, whereas, children with ADHD showed more impairments relative to non-affected controls in the CAFIS-parent. According to the Stroop color-word Test, FWT, and Digit span, executive function in children with TD did not differ from non-affected controls. Children with ADHD had poorer performance in measures of the Stroop color-word Test compared to children with TD. Conclusion : Children and adolescents with TD but not ADHD were not significantly different from non-affected controls on most measures of functional impairment and executive function. These findings suggest that an education program and intervention for children with TD would be important to reducing the stigma of TD.

Objectives : This study was designed to investigate depression, anxiety, alexithymia, stress res ponses in caregivers of patients with attention deficit hyperactivity disorder. Methods : The subjects were 38 attention deficit hyperactivity disorder patients caregivers(38 women, mean age $37.5{\pm}6.5$). Patients were diagnosed with DSM-IV ADHD criteria. Korean version of Beck Depression Inventory(BDI), State and Trait Anxiety Inventory(STAI), Toronto Alexithymia Scale(TAS) and Stress Response Inventory(SRI) were used for assessment. Results 1) The BDI scores of ADHD patients caregiver group were significantly higher than control group$(16.4{\pm}7.1\;vs.\;10.9{\pm}5.5)(p=0.011)$. 7 of the 38 caregivers(18.4%) and none of control group(0%) had BDI scores over 20 points(p=0.021). Calculated relative risk for ADHD in the presence of caregivers' depression was 1.516 overall(95% confidence interval, 1.234-1.862). 2) In ADHD patient's caregiver group, the scores of Stress Response Inventory were significantly higher than control group$(44.2{\pm}20.2\;vs.\;26.5{\pm}16.8)(p=0.006)$. 3) No significant differences were found in the score of STAI, SIAIS, SIAI-T, TAS between caregiver and control group. Conclusion : This study suggest that ADHD patients' caregivers are likely to have more depressive symptoms and higher stress response level than control group. We propose that physicians should consider integrated approaches for caregiver's psychopathology in the management of ADHD.
