Objectives : This study was conducted in order to examine the reliability and validity of the Childrens Color Trails Test (CCTT). The objective of the study was also to provide the Korean normative data for the CCTT. Methods : Normative samples consisted of 766 children and adolescents living in Seoul and aged from 5 to 15 years. Eighty children who were diagnosed with ADHD, based on the DSM-IV criterion, were recruited from Seoul National University Childrens Hospital. Among them, 46 ADHD children were receiving medication, while 34 children were drug-free. Results : The scores of the CCTT were significantly correlated with those of the Stroop test. Three factors were extracted through factor analysis-visual tracking and cognitive flexibility, distractibility and susceptibility to interference, and simple attention and impulsivity. The completion time of the CCTT for all children tended to decrease as age increased. There were significant differences in the CCTT scores between the ADHD group receiving medication, the ADHD-drug free group and the normal groups. The CCTT also showed sound test-retest reliability. These results confirmed the reliability and validity of the CCTT. Finally, we provided the Korean normative data for the CCTT. Conclusion : These results suggest that the CCTT is a reliable and valid test, which can be used to assess frontal function related to child psychiatric disorders in Korean children.

인간은 일주일 단위로 유사한 행동 패턴을 가진다고 한다. 이런 점에서 일주일 단위의 시간-공간 기록의 형태인 인간 이동 데이터를 이용하면, 인간의 행동 패턴을 유추해 낼 수 있다. 본 논문에서 인간의 행동을 유추하기 위해 BPN알고리즘을 사용하였다. BPN알고리즘에 대해 설명하고, 인간 이동의 예측에 관한 적용에 관한 BPN알고리즘의 설계 과정을 논의한다. 그리고 해당 실험의 결과와 분석을 제시한다.

윤수연(Soo-Youn Yoon),구훈정(Hoon-Jung Koo),김붕년(Boong-Nyun Kim),신민섭(Min-Sup Shin) 대한소아청소년정신의학회 2008 소아청소년정신의학 Vol.19 No.2
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.

주의력결핍/과잉행동장애와 양극성장애 공존 환아군과 주의력결핍/과잉행동장애 환아군의 비교연구
정동선,하규섭,정희연,구훈정,황준원,김붕년,신민섭,조수철,홍강의 大韓神經精神醫學會 2006 신경정신의학 Vol.45 No.6
Objective : Attention deficit hyperactivity disorder (ADHD) is frequently comorbid with a variety of psychiatric disorders. Among them, bipolar disorder (BPD) has especially attracted growing interest. This is partly due to the fact that early onset BPD has been frequently misdiagnosed as ADHD because of symptomatic overlap. The aim of the present study is to find the differences in demographic data and clinical features of ADHD+BPD and ADHD in children and adolescents. Method : Children and adolescents patients participating in the present study have been enrolled at the child psychiatric clinic since 2004. 14 patients meeting the DSM-IV chteria for ADHD+BPD and 19 patients meeting the criteria for ADHD and 15 healthy comparison subjects were recruited. All groups were evaluated through the Schedule for Affective disorders and Schizophrenia for School-Age Children-Present and Life Time version-Korean version (K-SADS-PL-K). Demographic data and clinical charactehstics of the subjects were also collected. Parents were asked to complete the Child Behavior Check List(CBCL) and the Toddler Temperamental Scale (TTS) clinical ratings were obtained using the Young Mania Rating Scale(YMRS), the Children's Depression Iventory (CDI) and the Dupaul ADHD scale. Clinical variables between ADHD+BPD and ADHD were analyzed using the Mann-Whitney U test. YMRS, CDI, Dupaul ADHD scale (inattention and hyperactivity), CBCL, and TTS among the three groups were analyzed using the Kruskal-Wallis test with post-hoc Mann-Whitney U test. Results : 1) ADHD+BPD group had an earlier onset age of ADHD than ADHD group 2) ADHD+BPD group had more co-morbid psychiathc disorders than ADHD group. 3) Compared to ADHD group, ADHD+BPD had more psychiathc family history, especially mood disorders. 4) ADHD+BPD group had prodromal symptoms such as irritability, anger dyscontrol and academic dysfunction, compared to ADHD group who rarely showed prodromal symptoms. 5) ADHD+BPD group had higher ADHD scores than the ADHD group in the Dupaul ADHD inattentive scale. 6) In global functions of CBCL, ADHD+BPD group showed more impaired functions at home and school than ADHD group. 7) In Attention diagnostic system (ADS), ADHD+BPD group had more omission and commission errors than ADHD group, especially in the visual system. 8) In the subtests of the IQ profile, ADHD+BPD group had lower arithmetic and block design scores than ADHD group. Conclusion : Clinicians have to rule out underlying bipolarity in children and adolescents with ADHD who show earlier age of onset and severe clinical features. Bipolarity should be explored intensively in ADHD children and adolescents who have early onset of symptoms and severe functional impairment.
