This study examined the relationship between hostility and obsessive-compulsive symptoms to clarify the differential role of overt hostility and covert hostility on obsessive-compulsive symptoms. In addition, this study examined whether impulsivity has a moderating effect on the relationship between hostility measures and obsessive-compulsive symptoms. The Buss Durkee Hostility Inventory (BDHI), Revised Obsessive Compulsive Inventory (OCI-R), and Barratt Impulsivity Scale (BIS) were used to measure hostility, obsessive-compulsive symptoms, and impulsivity, respectively. Data were collected from 150 online university students and analyzed using the correlation and moderated multiple regression model. The result showed that overt hostility was positively correlated with obsessive thoughts; covert hostility was positively correlated with obsessive thoughts and compulsive behavior. In addition, the regression results, which set the hostility variables as the predicting variable, revealed covert hostility to increase obsessive thinking and compulsive behavior, whereas overt hostility had no significant effect on both variables. Impulsivity was found to function as a moderator in the prediction of covert hostility on obsessive thought. With the result, the implications and limitations of this study are discussed.

Although obsessive-compulsive disorder(OCD) affects children, adolescents, and adults whether its juvenile(dhild and adolescent) and adult forms are different subtype of a disorder remains unknown. But there are increasing findings that suggest that juvenile OCD may be unique subtype of the disorder. One proposed subtype is the childhood OCD associated with high comorbidity of tic disorder and increased familial loading for OCD or tic disorder. The other proposed subtype is the childhood OCD and/or tic disorder occuring in association with streptococcal infection(PANDAS). These two subtypes of OCD are unlikely to respond to SSRI due to possible different pathphysiological mechanism. So this paper reviews the characteristics of OCD and therapeutic approaches for treatment resistant OCD in childhood and adolescence. Considering the likely heterogeneity of OCD, the possibility that juvenild OCD may be a variant of the disorder can have important clinical and scientific implications because it may further our understanding of this disorder, its etiology, and perhaps its treatment.

Objectives : This study was aimed to investigate the differences in intelligence and neuropsychological test findings between patients with obsessive-compulsive disorder(OCD) and normal controls, and to find out brain functions. Methods : To examine the brain functions, Halsted Reitan neuropsychological test, computerized neuropsychological test, Wechsler Memory scale and K-WAIS were applied. Subjects of this study consisted of 12 patients with OCD and 17 normal controls who were matched for age, handedness and education year. Results : The verbal intelligence of OCD was significantly higher than that of normal controls. But there was no significant difference in total and performance intelligence between groups. The total time of tactual performance test in OCD was significantly delayed than that in normal controls. Also the visual recall of Wechsler memory scale in OCD was more impaired than that in normal controls. Conclusion : These findings support that visual-spatial memory, which is related to basal ganglia, is impaired in OCD.

Objective : The aims of this study were to explore the relations of internet addiction to depression, impulsivity, and obsessive-compulsivity in adolescents. Methods : 1410 high school students (male=611, female=799 : mean age=$16.2{\pm}0.7$) were included in this study. The questionnaire consisted of items on demographic characteristics and internet use pattern. We assessed the level of internet addiction using Young's internet addiction scale (IAS) Barratt impulsiveness scale (BIS) and Maudsley obsessive compulsive inventory (MOCI) were also self-rated. In this study, We defined upper 25% of IAS as 'addiction group' and lower 25% as 'non-addiction group'. Results : The results were as follows ; 1) Male students had significantly higher mean scores on Internet addiction scale than females and there was significantly higher rate of male students in addiction group. 2) The addiction group spent more time for internet use, especially for games than non-addiction group. 3) The addiction group showed significantly higher total scores on BDI, BIS, and MOCI than non-addiction group. 4) Significant associations have been found between the level of internet addiction and depression, impulsivity, and obsessive-compulsivity, respectively. Conclusion : Depression, impulsivity, and obsessive-compulsivity could be significant factors predicting internet addiction. Especially, direct effect of impulsivity could be the most significant to explain internet addiction. Adolescents with high impulsivity may be vulnerable to internet addiction.

This study is to investigate the compulsive use of the social media platform, YouTube. For this purpose, this study built a research model that considered how the personality trait perspective(agreeableness, conscientiousness, neuroticism, extraversion, openness) and the use motivation perspective(utilitarian, hedonic and social use motivations) work together to explain compulsive use of YouTube. The survey method was used for this paper, and data from a total of 165 were used for the analysis. And structural equation model was used to analyze the data. The results of this empirical study is summarized as followings. First, both agreeableness and conscientiousness have a negative effect on compulsive use of YouTube. Second, utilitarian use motivation has a negative effect on compulsive use of YouTube. The results of this study are meaningful in that it not only alerts YouTube users to the risks of compulsive YouTube use, but also helps them to develop self-management strategies.

The purpose of this study is to develop the Leisure Obsession Scale and examine the validity of the scale. The Leisure Obsession Scale was developed and identified its validity by exploratory factor analysis, confirmatory factor analysis, and correlation analysis. The Leisure Obsession Scale consists of two factors, which are 'Leisure Preoccupation' and 'Leisure Stereotype'. Those two factors indicated the reasonable fit index by confirmatory factor analysis. In addition, this scale displayed discriminant validity via measurement of obsession, workaholism, leisure anxiety, and leisure constraint. Also, the results of criterion validation analysis shows that the Leisure Obsession Scale and its subscale are correlated with measure of age, leisure information searching, intention of participation to new leisure activities, and intention of increase in leisure time. Conceptualizing leisure obsession and exploring components of leisure obsession would be valuable for understanding the nature of leisure obsession and its effects on leisure satisfaction, and suggesting more effective psychological intervention in a diverse population.

Tic disorder including Tourette's disorder is a neurodevelopmental disorder that appears in childhood and characterized by the presence of motor and vocal tics. Childhood-onset obsessive-compulsive disorder (OCD) is suggested to be a phenomenologically and etiologically distinct subtype of OCD, bearing a close genetic relationship to tic-disorders. Tourette's disorder and OCD are comorbid in $40-75\%$ of patients initially diagnosed with either disorder. Basal ganglia and cortico-striato-thalamic circuits are implicated in the pathophysiology of both disorders and these disorders have similar clinical features. Over the past decades, the progress in research on Tourette's disorder and OCD has been extraordinary. This review describes some of important insights from these work, involving these areas : 1) clinical implication 2) genetics and epidemiology 3) brain imaging study 4) neuroche-mistry 5) pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS).

The purpose of this study was to develop a scale for measuring obsessive compulsive and to verify structural validity from students participating in physical education class. The procedure for this purpose was firstly conducted through an open questionnaire, followed by item search and appropriateness assessment, then analyzing the reliability of the final version based on the preliminary criterion and checking the construct validity. After analyzing the factors of the criticism, We collected the data and analyzed the items and the factors from 387 respondents. The subjects were social obsession (4 items), psychological obsession (3 items) and physical obsession (3 items) The final determinant of the 10 factors was completed. We conducted A multivariate analysis on the determinants of gender and class satisfaction to confirm the external relationship review. The reliability of the scale developed in this study showed not only a high level of confidence from .856 to .907, but also reasonized and proved to be an obsessional scale for physical education for the promotion of life care. These measures can be used as a data for measuring physical education compulsion in class.

Objective：The objective of this study is to examine the clinical characteristics and behavioral comorbidity of patients with Tourette’s disorder. Method：Subjects consisted of 157 patients with Tourette’ disorder diagnosed by DSM-IIIR, who were examined and diagnosed from Jan. 1988 to May 1994 at the Tourette’s Clinic of Yonsei University Medical Center. Characteristics and behavioral comorbidity of Patients were assessed by a semi-structured interview schedule. Behavioral problems like hyperactivity, obsession-compulsion, self destructiveness, enuresis, sleep problem were assessed by global clinical impression. Results：The mean age of patients was 14.49(${\pm}7.99$) years. Patients consisted of 138 males (87.9%) and 19 females(12.1%). The sex ratio was 7：1, showing a male preponderance. The number of right-handers was 133(84.7%), and the number of non-right handers was 24(15.3%). Mean age of onset was 8.85(${\pm}4.56$) years, ranging from 2-to-16 years. More than half of the patients had their age of onset at 6-10 years. Bimodal peak in age of onset was observed；the first peak was around 6 and the second peak was around 10 years. There was no sex difference in bimodal age of onset. The most common initial symptom was eye blinking. More than 55% of patients reported eye blinking as their first symptom. The second common initial symptom was head turning and the third was vocal tic. The most common symptoms that patients reported on their first visit since onset were eye blinking(82.2%), head turning or nodding(57.9%), shoulder shrugging(52.7%) and forearm movement(32.6%). Of 157 cases, 101(64.3%) patients showed downward progression of symptoms, and 25(15.9%) showed upward progression of symptoms. Nineteen fathers(12%) of patients had a past history of obsessive-compulsive disorder(OCD). Seventeen fathers(10.6%) had a history of tic disorder. SSevenmothers(4.5%) had OCD, 4 mothers (2.5%) had tic disorder. One hundred and eighteen patients(75.1%) had comorbid hyperactivity, 95 patients(60.5%) had obsession, 55 patiens(35.0%) had self destructiveness, 46 patients(29.3%) had impulsivity, and 35 patients(22.3%) had enuresis. Age of onset had a significant positive correlation with age, duration, and the global severity of obsession；and a negative correlation with the severity of hyperactivity. Hyperactivity had a significant positive correlation with impulsivity, obsession-compulsion, enuresis, and self destructiveness. Obsession-compulsion had a significant positive correlation with hyperactivity, sleep problems, and self destructiveness. Conclusion：These data suggest that clinical characteristcs and behavioral comorbidity of patients with Tourette’ disorder in this study are similar to previous research findings in Korea and other contries. The younger the age of onset was, the more severe hyperactivity was, and the less severe obsession-compulsion was. And severity of hyperactivity had a positive correlation with the severity of obsession-compulsion, impulsivity, enuresis, and self destructiveness.

A 12-year-old girl with a 6 year history of childhood-onset schizophrenia required 2 hospitalizations and long-term clozapine trial due to inadequate responses to combinations of typical neuroleptics and traditional treatments of schizophrenic disorder. On admission, she had continuous auditory and visual hallucinations, persecutory delusion, emotional instability, regression of behaviors including temper tantrums as well as specific developmental delays in learning, language, and motor coordination. The clozapine trial significantly reduced most of the positive symptoms, and facilitated in successful discharge from the hospital. During the 4 year clozapine treatment, no significant adverse reactions were noted, and she returned to a structured school setting with minimal degrees of schizophrenic symptoms. From this clinical experience, we suggest that clozapine might be safe and effective in treating treatment-refractory schizophrenic children.
