Abstract PDF: BACKGROUND
The causes of ADHD(attention deficit hyperactivity disorder) are various, it is impossible to understand the whole characteristics of ADHD, only with simple intellignece testing scales. We compared cognitive characteristics of ADHD group with normal controls with Korean Kaufman Assessment Battery for Children(K-ABC), It is well known to evaluate neuropsychological and cognitive aspects of the children. MATERIALS AND METHODS: Age and sex matched 40 ADHD patients and 40 normal controls tested with the K-ABC. Each subscales compared between pre-treatment patients and controls, pre-treatment and post-treatment in patient group, post-treatment patients and controls. RESULTS: Significant differences are ovserved in sequential processing, simultaneous processing, cognitive processing and achievement between pre-treatment patients and controls, and in gestalt closure between pre-treatment and post-treatment patients group. But there are no significant differences between pre-treatment patients and controls in gestalt closure and reading/decoding. CONCLUSIONS: Methylphenidate improved the scores of simultaneous scale, which means improvement of executive functions such as divided attention, analysis and organization. Methylphenidate also reduced distractibility.

Abstract PDF: The purpose of this study was to examine the reliability and validity of attention deficit disorder evaluation scale-school version(ADDES-SV). Between October 1996 and November 1996, ADDES-SV was administered to 263 elementary school students in the second grade and between Jun 1996 and October 1996, 28 attention deficit hyperactivity disorder patients. In the reliability test, the test-retest reliability coefficient was significantly high and that of inattention was 0.88, that of impulsivity was 0.80, that of hyperactivity was 0.83 and total score was 0.83. In the reliability test by internal consistancy, the Cronbach alpha coefficient was significantly high and that of inattention was 0.98, that of impulsivity was 0.87, that of hyperactivity was 0.87(p<0.05). The half-sprit reliability coefficient by first-second half method showed high correlation and that of inattention was part 1: 0.96, part 2: 0.96 impulsivity was part 1: 0.95, part 2: 0.93, hyperactivity was part 1: 0.92, part 2: 0.94(p<0.05). Inter-rater reliability by pearson correlation coefficient was significantly high and that of inattention was 0.92, that of impulsivity was 0.87, that of hyperactivity was 0.89 and total score was 0.89. The concurrent validity between ADDES-SV and CAP scale was 0.85 in attention deficit hyperactivity disorder patient group and 0.79 in normal control group(p<0.05). In discriminant validity test between attention deficit hyperactivity disorder patient group and normal control group, the patient group showed higher score(p<0.05). The total discriminant capacity of the patient group in ADDES-SV was 94.6%. In this point of view, ADDES-SV scale showed high reliability and validity in applying to Korean subjects and was proved to be the useful screening test tool for attention deficit hyperactivity disorder research.

Abstract PDF: The purpose of this study was to examine the reliability and validity of a Korean form of Childhood Attention Problem(CAP) scale. CAP were administered to 98 normal elementary school students as control group and 98 attention deficit hyperactivity disorder patients. Male students showed high scores than female students in both subscale and total scores, but not statistically significant. There were no significant difference in CAP scale between male students and female students in attention deficit hyperactivity disorder patients. In the reliability test, the test-retest reliability coefficient was highly satisfactory and that of inattention subscale was 0.83, impulsivity subscale was 0.70 and total score was 0.82. In the reliability test by internal consistency, the Cronbach a coefficient was highly satisfactory and that of inattention subscale was 0.91, overactivity subscale was 0.89(p<0.05). The concurrent validity between CAP scale and ADDES-HV scale was 0.85 in attention deficit hyperactivity disorder patient group and 0.73 in normal control group(p<0.05). In discriminant validity test between attention deficit hyperactivity disorder patient group and normal control group, the patient group showed higher score(p<0.05). The total discriminant capacity of the patient group in CAP was 93.4%. In this point of view, CAP scale showed high reliability and validity in applying to Korean subjects and was proved to be the good and simple screening test tool for attention deficit hyperactivity disorder research and can help many young patient to treat early.

Abstract PDF: In order to survey the reality of anxiety and depression among the Koreans residing in china, a study was conducted between January and March of 1991, on the residents of Yun-Kil city, with subjects of 472 Koreans and 479 Chinese. The evaluation was based on the questionnaires, named Combined self-rating anxiety depression scale (CADS), distributed among the subjects. ANOVA and t-test were applied for data processing. The results were as follows: There was not significant difference in the mean of total scores between the two groups. The scores of Koreans were 29.70±7.03, while those of Chinese were 29.45±9.01. The score of the CADS above 50 (clinically significant level) was seen in 12 (2.54%) Koreans and 21 (4.38%) Chinese. The anxiety-depression scores relating to the items of indigestion and decreased appetite, sleep disturbance, apprehension, decreased libido were relatively high among the Koreans. The items appeared low in scores among the Koreans were faintness, fear, suicidal rumination, hopelessness, paresthesias. The highs among the Chinese were facial flushing, anxiousness, dissatisfaction, suicidal rumination. The items appeared low among the Chinese were fear, faintness, paresthesias, weight loss, suicidal rumination. In the compatison of evaluation by items between the two groups, the items placing the Koreans significantly higher over the Chinese are indigestion & decreased appetite, sleep disturbance, apprehension, decreased libldo. The Chinese marked significantly higher in facial flushing, anxiousness, dissastisfaction, suicidal rumination. Those in the case of female (p<0.01 respectively), less than twenty years old (p<0.01 respectively), dissatisfied with family relationship (p<0.01 respectively), with past history of psychiatric hospitalization (Koreans p<0.01, Chinese p<0.05), pessimistic toward future, present, past self image (p<0.01 respectively) had significantly higher scores in both groups. In religion, neither group showed significant difference. In religion, neither group showed significant difference. In marital status, the Koreans showed a higher degree of divorce and separation and the Chinese in singleness (p<0.01 respectively). The Korean were higher in illiteracy and the Chinese had more college education (p<0.01 respectively). In place of growth, The Koreans showed not much difference in the areas while more Chinese grew up un large cities (p<0.01). More Koreans lived in the dormitory while the Chinese were engaged more in self-cooking (p<0.01 respectively), In pocket money per mouth, more Koreans were less than 1 dollar while the Chinese were between 7 and 10 dollars (p<0.01 respectively). There were no significant difference between two groups about religion.

Abstract PDF: In order to make transcultural research for mental health centered on anxiety and depression between two countries of which psychosocial factors are different, the author studied 698 Nepalese in Dolka in January 1990 and 417 Korean of Chungdo and Kyungju in Korea from July to August 1990 by using the Combined Self-Rating Anxiety Depression Scale (CSADS). The author applied t-test and ANOVA to compare these two groups. The results were as follows: The total scored of Nepalese scored 51.27±11.10 while Korean Scored 44.29±11.79. The anxiety-depression scores relating to the items of restlessness, depressed affect, apprehension, crying spells and fatigue were significantly high in Nepalese, while fatigue, sleep disturbance, dissatisfaction, dizziness, and anxiousness were significantly high in Korean. Both groups showed an increase of score with age. The item relating to education, the scores of the CSADS was significantly high in lower education level in Nepal but Korean showed no significant difference among education level. The score of the CSADS above 50 (clinically significant level) was seen in 361 (51.7%) Nepalese and 116 (27.9%) Korean, which shows the proportion of Nepalese are significantly higher than that of Korean.
