We investigated the self-concept, subjective depression, and state-trait anxiety of the school boys with learning disabilities(abbr. LD, n=86) and compared them with normal boys(n=52) using Piers-Harris Self-Concept Inventory, Child Depression Inventory(abbr. CDI), and State-Trait Anxiety Inventory(abbr. STAI). With regard to Piers-Harris Self-Concept Inventory total scores, there was no significant difference between two groups, but normal boys showed higher scores in intellectual and school status, physical appearance, and happiness-satisfaction subscales than patients with LD. The male patients with LD showed significantly higher ratings in CDI total scores, and CDI subscales - ineffectiveness, anhedonia, negative self-esteem than normal children. The patients with LD reported significantly higher state anxiety, but not trait anxiety. Correlation analyses revealed that self-concept decreased over time, and depression-anxiety increased across grades in the patients with LD, but not in normal children. Especially, negative mood, anhedonia, negative self-esteem subscales of CDI, and state-trait anxiety showed significant positive correlation with grades. In both groups, CDI scores were inversely correlated with Piers-Harris Self-Concept and positively with State-Trait anxiety. In conclusion, self-concept problems which were related with school achievement and self-esteem were more abundant in the patients with LD than normal children, self-image problem, depression and anxiety increased across grades. According to regression analysis, age, behavior subscale, intellectual-school status, anxiety, popularity, happiness-satisfaction, CDI-ineffectiveness, interpersonal problem, negative self-esteem, and state anxiety could explain the self-concept in the patients with LD, not in normal children. So, the self-concept of the patients with LD were found to be related to the school achievement and stress when comparing with peers. In conclusion, elementary school boys with LD showed lower self-concept, higher depression and anxiety, and these differences increased across grades. Since the patients with LD have concomitant depression and anxiety disorders, it is important that comorbidity with emotional problems should be explored and managed properly.

1. Purpose of study : In Oriental Traditional medicine, especially in Sasang Constitutional Medicine the mind and the body are not separated. Psychological characteristics are very important as well as physical characteristics in Sasang Constitutional Medicine. This study was performed to investigate the psychological characteristics of Sasang Constitution. 2. Subjects and Methode of Study : Subjects were 63 persons. There were male 54 and female 9 who were healthy. There were Taeumin 35, Soumin 17, and Soyangin 11. We judged Sasang Constitution in QSCC II and the diagnosis by a medical specialist. The degree of depression and anxiety was determined by Beck's Depression Inventory(BDI) and State-Trait Axiety Inventroy(STAI, State Anxiety : S-A, Trait Anxiety : T-A). We studied the psychological characteristics - Depression and Anxiety - in the Sasang Constitution by analyzing BDI and STAI scores. 3. Result of study : 1) The score of STAI(S-A) in Soeumin(少陰人) group was significantly higher than that in Taeumin(太陰人) group. 2) The score of STAI(T-A) in Soeumin(少陰人) group was significantly higher than that in Taeumin(太陰人) group and Soyangin(少陽人) group. 3) The score of BDI in Soeumin(少陰人) group was higher than that in Taeumin(太陰人) group and Soyangin(少陽人) group, but it was not significant statistically. 4. Conclusion of study These result suggest that Soeumin(少陰人) is more anxious than Soyangin(少陽人) and Taeumin(太陰人).

Objectives : The aim of this study was to investigate the relationship between the norepinephrine(NET) transporter T-182C polymorphism and anxiety-related traits in Korean adolescent females. Methods : One hundred sixty-nine Korean adolescent females were tested for the NET T-182C polymorphism by PCR based methods; anxiety-related traits were evaluated using the anxiety sensitivity index(ASI) and the trait form of the Spielberg State-Trait Anxiety inventory(STAI-T). Results : Scores of anxiety related traits were not different between genotypes. Comparison between T allele carries and non carriers revealed no significant difference. Conclusion : These findings suggest that the NET T-182C polymorphism is not associated with anxiety-related traits in Korean female adolescents.

Purpose: It has been reported that children with chronic pain have higher levels of anxiety than age-matched controls. Therefore, this study was designed to determine the relationship between anxiety and recurrent abdominal pain in elementary school children. Methods: In 2005, we surveyed 1,254 elementary school children (592 boys and 662 girls) whose ages ranged from 7 to 12 years. The degree of trait and state anxiety was compared between agroup suffering from intermittent abdominal pain, a group suffering from recurrent abdominal pain and a normal control group following the Korean version of Spielberger's State-Trait Anxiety Inventory YZ form (STAI-YZ). Results: 709 (56.5%) and 69 (5.5%) of the patients reported intermittent abdominal pain and and recurrent abdominal pain, respectively, during the 12 month period before this study was conducted, and trait and state anxiety values for each of these groups was 116 (9.3%) and 63 (5.0%), respectively. In addition, the State-Trait Anxiety score was significantly higher in the group with intermittent abdominal pain and RAP than the anxiety score of the normal control group. Additionally, the STAI-YZ score increased in proportion to the severity of abdominal pain, but was not correlated with the duration, frequency, onset time or location of abdominal pain. Furthermore, the proportion of the group with abdominal pain in the group that had trait or state anxiety was significantly higher than the proportion of the group that did not have trait and state anxiety. Conclusion: Recurrent abdominal pain during childhood is correlated with state and trait anxiety, therefore, psychological factors, such as anxiety duringtreatment, must also be considered when determining the cause of recurrent abdominal pain.

Objectives: A number of studies have shown that sleep deprivation results in reduced vigilance and increased negative affects such as tension, depression and anger. However there are few studies about effects of sleep deprivation on anxiety. The purpose of this study was to investigate the effects of 40 hour sleep deprivation on state anxiety, affects, sleepiness and fatigue. The authors also intended to study the effect of trait-anxiety on these psychological variables after sleep deprivation. Methods: Twenty nine subjects(22 men, 7 women, $24.59{\pm}1.35$ years of age) participated in this study. Subjects had no past history of psychiatric disorders and physical illnesses, and had normal sleep-waking cycle without current sleep disturbances. All of the subjects completed sleep dairy for two weeks to exclude some who suffered from chronic sleep deprivation or sleep disturbances. Subjects were instructed to get a normal sleep as usual at night before the study. After awakening, subjects remained awake for 40 hours under continuous surveillance. They completed State-Trait Anxiety Inventory, Index of General Affect, Stanford Sleepiness Scale and Fatigue Questionnaire every three hours, therefore they completed the scales 14 times totally. Subjects were dictated not to take caffeine, alcohol, or any medications on the day of the study. Heavy exercises and naps were restricted too. Results: Sleep deprivation resulted in increased state anxiety, negative general affects, and increased sleepiness and fatigue(p<.001). Dividing into high trait-anxiety group and low trait-anxiety group, there was significant sleep deprivation x traitanxiety interaction effect on general affect(p<.05). But, there was no significant sleep deprivation x trait-anxiety interaction effect on state-anxiety, sleepiness and fatigue. During sleep deprivation, the highest ratings of scales on anxiety, negative affect, sleepiness and fatigue occurred between 4 : 00AM and 7 : 00AM. Conclusions: These results show that sleep deprivation results in increased anxiety, mood state disturbance and increment of sleepiness and fatigue. These findings also suggest that trait-anxiety is a factor that influences the degree of worsening in general affect caused by sleep deprivation. During sleep deprivation, the rating curves of anxiety, affect, sleepiness and fatigue show rhythmicity that may be related to circadian rhythm.

Objectives：This study was to investigate the impact of parental psychiatric disorder on offspring's depression, anxiety, self concept, perception of familial relationship compared with offspring of normal control. In offsprings of parents with psychiatric disorder, this study explored whether their psychopathology, self concept, and perception of familial relationship were influenced by parent’s sex, onset time of parent’s psychiatric disorder and parent’s psychiatric diagnosis. Methods：52 offsprings aged 10-18 years of 39 psychiatric outpatient were surveyed from June, 1997 to April, 1998 and completed several questionnaaire, including Korean from of the Family Environment Scale, Korean form of the State-Trait Anxiety Inventory for Children, Korean form of Kovac’s Children’s Depression Inventory, and Korean form of Piers-Harris Children’s Self-Concept Scale. Their score was compared with offsprings’ of normals. In offsprings of parents with psychiatric disorder, they were compared according to parent’s sex, onset time of parent's psychiatric disorder and parent’s psychiatric diagnosis. Results：The results were as follows：1) Offsprings of parents with psychiatric disorder reported higher level of state anxiety and lower level of the FES expressive subscale than offsprings of normals(p<0.05). But they reported higher level of PHCSCS intellectual & school status subscale and popularity subscale than normals(p<0.05). 2) There were no differences in anxiety, depression, self concept, and perception of familial relationship between patient’s sex. 3) Offsprings less than 3 years old when parent’s psychiatric disorder had developed showed higher level of trait anxiety and lower level of FES control subscale than offsprings more than 3 years old (p<0.05). 4) There were no diferences in anxiety, depression, self concept, and perception of familial relationship between patient’ diagnostic groups(schizophrenia spectrum disorder-mood disoderneurosis). Conclusion：The finding indicated that self reported scale of anxiety and depression showed no significant difference between offsprings of psychiatric patients and offsprings of normals. In offsprings of parents with psychiatric disorder, parent’s sex and psychiatiric diagnosis had no influence on offspring’s psychopathology. But the offspring’s age(before 3 years old) when the parent’s psychiatriric disorder developed had influence on higher level of offspring’s trait anxiety. For further high risk group study, direct interview and evaluation of parent-child agreement or teacher-child agreement will be needed in longitudinal study.

The purpose of this study was to determine whether parenting stress is related to anxiety in children with ADHD. The data were provided by 112 children between the ages of 7 and 9. Forty nine children with a diagnosis of ADHD were recruited through 3 departments of child psychiatry and 63 normal children were recruited from elementary schools from the same city. The Korean version of Parenting Stress Index-Short Form was used to assess parenting stress and the Korean version of the State Trait Anxiety Inventory for Children was used to assess the level of anxiety. The results show that children with ADHD have significantly higher levels of anxiety and parenting stress than normal children. However, no significant differences in parenting stress and anxiety were found across gender, age, and the type of ADHD. Significant correlation was found between trait anxiety and parental distress and between state anxiety and difficult child. Parenting stress didn't significantly influence on anxiety in children with ADHD. Occupational therapist need to consider that the anxiety level of children with ADHD is different from normal children. It is needed for interventions for children with anxiety symptoms and also consultation and intervention for parents with parenting stress.

Objectives : We have studied female patients with either alopecia areata or androgenetic alopecia to evaluate psychological aspects, such as anxiety, depression, alexithymia, and characteristic personalities. In addition, we tried to examine the differences in psychological characteristics between these two types of alopecia, where the alopecia areata has been cotroversial on the role of stress in its etiology and the androgenetic alopecia seems to be more influeced by genetic and biological factors. Methods : All participated patients were females with alopecia for more than 1 you. Among them, 52 were with alopecia areata and 33 were with androgenetic alopecia. They were compared with 54 normal healthy controls by using MMPI, BDI, STAI-S, STAI-T, and TAS-20K. Results The average scores of F, Hs, D, Pd, Pa, Sc, Si in MMPI of alopecia groups were significantly higher than that of normal controls, and the androgenetic alopecia group had highest Hy and Pt scores. The average scores of BDI, STAI-S, and STAI-T in alopecia groups were higher than the normal controls. 94.2% of alopecia areata patients and 97.0% of androgenetic alopecia patients had severe depression, who scored higher than 23 in BDI. In TAS-20K, the average total scores of alopecia groups were higher than the normal control group, and the average Factor 3 score in androgentic alopecia was higher than the other groups. The alopecia groups scored higher than normal control group in STAI-S and STAI-T. Conclusion : Females with chronic alopecia were more depressed, had higher levels of anxiety, and more alexithymic than normal healthy females. In spite of arguments about etiological role of stress to alopecia, psychiatric interventions are needed for depression, and considerations for personality and psychological defense mechanism were needed in both types of alopecia.

Objectives：We developed a Korean version of the Brief Measure of Worry Severity(BMWS), and examined its reliability, validity, and factor structures. We also explored the associations of pathological worry with depression and anxiety. Methods：Three hundreds fifty-two subjects including community population and college students completed the BMWS, and 27 subjects repeated the scale three weeks later. Reliability was assessed by Cronbach's coefficient ${\alpha}$ and test-retest correlation. The external validity was examined by the correlation of the BMWS score with the scores of Beck Depression Inventory(BDI), Patient Health questionnaire-2(PHQ-2), State Anxiety Inven-tory(SAI), and Trait Anxiety Inventory(TAI). And principal component analysis was performed to evaluate the construct validity. The associations of pathological worry with depression and anxiety were explored using partial correlation analysis. Results：Cronbach's coefficient ${\alpha}$ for the BMWS was 0.904 and test-retest correlation was 0.56(P<0.01). The Spearman correlation coefficients of the BMWS score with the scores of BDI, PHQ-2, SAI, and TAI were 0.60(P<0.01), 0.42(P<0.01), 0.36(P<0.01), and 0.59(P<0.01), respectively. The BMWS showed unifactorial construct. When controlling for TAI score, the correlation coefficient between the BMWS score and the BDI score was 0.357(P<0.01), and when controlling for BDI score the correlation coefficient between the BMWS score and the TAI score was 0.446(P<0.01). Conclusion：The Korean version of the BMWS was found to be a reliable and valid questionnaire for measuring pathological worry. And we could identify the associations of the pathological worry with depression as well as anxiety.
