Objectives : Childhood depressive disorder one of the most prevalent chronic health conditions affecting school aged children. The objective of this study was to examine the prevalence and epidemiological characteristics of childhood depressive disorder in Korea. Methods : In this study, a survey was conducted of elementary school children in the Cheonan area from September 2009 to August 2010. A total of 12,084 children were included in the analyses. The primary measure of depression was the 27-item Kovacs' Children's Depression Inventory (CDI), the Korean Dupaul attention-deficit hyperactivity disorder Rating Scales (K-ARS), Autism Spectrum Screening Questionnaire (ASSQ) and Restless Legs Syndrome Questionnaire (RLSQ) were also administered. Results : The prevalence rate of childhood depressive disorder was 3.07%. The mean age was $9.21{\pm}1.81$ years for the control group (5,969 male, 6,054 female) and $9.91{\pm}1.83$ years for the depression group (CDI score${\geq}$22 ; 159 male, 210 female). Age, height, weight, and economic status were similar for the two groups. However, there were statistically significant differences in the distribution of sex. The distribution of school grade also differed between the two groups. Scores for CDI, K-ARS, and ASSQ in the depressive group were higher than those of the control group. Conclusions : This is the first large-scale population-based study to report on the prevalence of childhood depressive disorder in South Korea. Increased rates of childhood depressive disorder, as reported by primary caretakers, might reflect the increasing negative impact of environmental risk factors on neurobehavioral health. Longitudinal study of the prevalence of childhood depressive disorder should be considered for further evaluation.

Objective : The aim of this study is to identify the relationship between childhood abuse and affective symptom including resilience in patients with depression or anxiety. Methods : A total 256 outpatients diagnosed with depressive disorder or anxiety disorder according to DSM IV-TR, were evaluated with Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Parent-Child Conflict Tactics Scale (PCCTS), Connor-Davidson Resilience Scale (CD-RISC). Independent t-test, Chi-square analysis and analysis of covariance (ANCOVA) were performed to identify the demographics of patients and the relationship between affective symptoms including resilience and childhood abuse. Results : Among demographic and clinical variables, patients with childhood abuse history were significantly higher rate in patients who were living alone and unemployed. In affective symptoms, patients with childhood abuse history were significant more severe in depressive symptoms, and state anxiety score than patients without history of childhood abuse. Patients with childhood abuse history had higher score for trait anxiety and lower score for resilience than patients who had no history of childhood abuse. Conclusion : These finding suggest that history of childhood abuse might be risk factor on depressive and anxiety symptoms severity. And this might be a predictable factor of poor treatment outcome.

Objectives Psychological resilience plays a significant role in many aspects of mental health. The aim of this study was to find an association between childhood attention deficit hyperactivity disorder (ADHD) features and adulthood psychological resilience in patients with mood disorders. Methods A total of 213 patients with mood disorders including major depressive disorder or bipolar I, II disorder and 909 healthy controls were included. We assessed childhood ADHD features using the Wender Utah Rating Scale (WURS), adulthood psychological resilience using the Connor-Davidson Resilience Scale (CD-RISC), and current depressive mood using the Beck Depression Inventory (BDI). Pearson's correlation, multiple linear regression and a mediation analyses were performed to examine the relationships between three WURS factor (impulsivity, inattention, and mood instability) scores, the BDI score, and the CD-RISC score. Results The CD-RISC score was negatively correlated with the WURS childhood inattention factor score and current BDI score in patients with mood disorders. BDI score mediated the influence of the inattention factor score on CD-RISC score among patients with mood disorders. The CD-RISC score was significantly lower in patients with mood disorders than in controls even after controlling for age, WURS scores, and the BDI score. Conclusions An evaluation of psychological resilience is important for enhancing recovery and quality of life in patients with mood disorders. When assessing psychological resilience, current depression and ADHD features in childhood, particularly inattention, should be considered.

Objectives : The early onset of mood symptoms in bipolar disorder has been associated with poor outcomes in many studies. However, aspects of the clinical course of bipolar disorder in children and adolescents are controversial. The goal of this article is to review the clinical characteristics and longitudinal course of children and adolescents with bipolar disorders. Methods : Searches were conducted in MedLine, PsycINFO, KISS, and RISS using the terms phenomenology, clinical course, outcome, BPD, pediatric, children and adolescents. Twenty-one reports were selected : either original articles reporting symptoms and clinical characteristics of subjects (ages 5-18 years), or published articles in reviewed journals about bipolar disorder in children and adolescents. Results : Approximately 70% of subjects with bipolar disorder recovered from their index episode, and 50% had at least 1 syndromal recurrence, particularly depressive episodes. For 60% of the follow-up time, subjects had syndromal or subsyndromal symptoms with numerous changes in symptoms and shifts of polarity. Approximately 20% of BP-II subjects converted BP-I. Conclusion : Bipolar disorders in children and adolescents are characterized by episodic illness with subsyndromal and syndromal episodes with mainly depressive and mixed symptoms and rapid mood changes. Extensive follow-up time is needed to evaluate the continuity of bipolar disorder symptoms from childhood to adulthood.

Objectives: Oppositional defiant disorder (ODD) is often comorbid with other psychiatric disorders in childhood. This study aimed to investigate comorbid psychiatric symptoms and associated factors in elementary school children with symptoms of ODD. Methods: The participants consisted of 205 mother-offspring pairs. Psychiatric symptoms were measured using the Diagnostic Predictive Scales and Korean Child Behavior Checklist. Psychiatric comorbid symptoms were compared between children with ODD symptom and those without ODD symptom. Multivariate logistic regression analysis was used to estimate the odds ratio of psychiatric symptom on ODD. Results: ODD group had a significant association with internalizing and externalizing problem (p=0.001, p<0.001, respectively). ODD group were more comorbid with anxiety disorder, depressive disorder, attention-deficit/hyperactivity disorder, and conduct disorder. Among psychiatric disorder, generalized anxiety disorder (GAD) (adjusted odds ratio [AOR]=18.620, p<0.001) and conduct disorder (AOR=9.529, p=0.014) were associated with ODD symptom. Conclusion: These findings suggest that children with ODD symptom had significantly higher rates of comorbid psychiatric symptoms. And GAD and conduct disorder are related to ODD symptom.

Ovjectives: As the attention devoted to children's mental health increases, medical costs and burdens mount as well. In the present study, we evaluated the association between socioeconomic status(SES) and major child psychiatric symptoms. Methods: The subjects of this study were children of recruited from a mental health screening program in the Seoul Sungbuk mental health center over the course of 3 months. To establish the SES of each child, we collected data about each child's medical insurance, years of parental education, household income, family structure and housing. 149 children & parents completed questionnaires including the Childhood Depression Inventory(CDI) and the Korean Attention Deficit Hyperactivity Disorder Rating Scale(K-ARS). Results: The mean K-ARS-P score was $12.1{\pm}11.1$ and the suspected prevalence of ADHD was 20.8%(n=31). The mean cm score was $12.9{\pm}7.9$, and the prevalence of suspected depression was 16.8%(25). Depressive symptoms and ADHD symptoms were both more severe than those observed in a previous epidemiologic study in Korea. Depressive symptoms were more closely associated with family SES status. Conclusion: SES status is one of the most important risk factors in the development of major child psychiatric symptoms. In our study we found that depressive symptoms in particular were most tightly associated with psychosocial factors. Evaluation of the risk factors, early screening and intervention for low SES children would be valuable mental health management tactics to implement in a community mental health system.

Objectives: This study aimed to examine the trend in diagnostic prevalence of psychiatric disorders in children and adolescents. Methods: Individuals aged 0-18 years were included in the study based on the National Health Insurance Claims Data. To investigate the trends in diagnosis and diagnostic prevalence of psychiatric disorders reflecting the decrease in the birth rate, data were analyzed from 2010 as a reference year to 2015. Results: The number of patients diagnosed with psychiatric disorder decreased annually, from 23,412 on 2010 to 18,821 on 2015. The most common disorder was hyperkinetic disorder in male and depressive episode in female. Although there was no significant change in overall diagnostic prevalence rate of psychiatric disorders, age groups <10 years and some disorders had significant changes in prevalence rate. This study classified the diagnostic prevalence by age into two unique patterns: group in which the diagnosis rate increases with age and group in which the diagnosis rate peaks at a certain age and then decreases. Conclusion: Diagnostic prevalence of psychiatric disorders was different according to age and sex. These patterns should be reflected in the formulation of policies related to mental health and in medical practice for pediatric patients. It is urgent to identify how these patterns change in young adults.

Objectives : This study aimed to investigate the psychosocial characteristics of functional gastrointestinal disorder (FGID) in patients with psychiatric disorders. Methods : This study was conducted with 144 outpatients visiting the psychiatric clinic at a university hospital. FGIDs were screened according to the Rome III questionnaire-Korean version. Demographic factors were investigated, and psychosocial factors were evaluated using the Hospital Anxiety Depression Scale, Patient Health Questionnaire-15, Childhood Trauma Questionnaire-Korean, and State-Trait Anger Expression Inventory. Chisquared test and student's t-test were used as statistical analysis methods. Results : There were differences in education level between two groups divided according to FGID status (${\chi}^2=10.139$, p=0.017). Comparing the psychiatric disorder by FGID group, irritable bowel syndrome (IBS) group showed significant differences (${\chi}^2=11.408$, p=0.022). According to FGID status, IBS group showed significant differences for anxiety (t=-3.106, p=0.002), depressive symptom (t=-2.105, p=0.037), somatic symptom (t=-3.565, p<0.001), trait anger (t=-3.683, p<0.001), anger-in (t=-2.463, p=0.015), and anger-out (t=-2.355, p=0.020). Functional dyspepsia group showed significant differences for anxiety (t=-4.893, p<0.001), depressive symptom (t=-3.459, p<0.001), somatic symptom (t=-7.906, p<0.001), trait-anger (t=-4.148, p<0.001), state-anger (t=-2.181, p=0.031), anger-in (t=-2.684, p=0.008), and anger-out (t=-3.005, p=0.003). Nonerosive reflux disease group showed significant differences for anxiety (t=-4.286, p<0.001), depressive symptom (t=-3.402, p<0.001), somatic symptom (t=-7.162, p<0.001), trait anger (t=-2.994, p=0.003), state anger (t=-2.259, p=0.025), anger-in (t=-2.772, p=0.006), and anger-out (t=-2.958, p=0.004). Conclusions : Patients with psychiatric disorders had a high prevalence of FGID, and various psychosocial factors contributed to such differences. Therefore, the psychiatric approach can offer better understandings and treatments to patients with FGID.

The purpose of this study is to find out the characteristics of depressive episode about major depression and bipolar disorder in child and adolescent. The subjects of this study were 34 major depression patients and 17 bipolar disorder patients hospitalized at child and adolescent psychiatry in OO university children's hospital from 1st March 1993 to 31st October 1999. The method of this study is to review socio-demographic characteristics, diagnostic classification, chief problems and symptoms at admission, frequency of symptoms, maternal pregnancy problem history, childhood developmental history, coexisting psychiatric disorders, family psychopathology and family history and therapeutic response through their chart. 1) The ratio of male was higher than that of female in major depressive disorder while they are similar in manic episode, bipolar disorder. 2) Average onset age of bipolar disorder was 14 years 1 month and it was 12 years 8 months in the case of major depression As a result, average onset age of major depression is lower than that of bipolar disorder. 3) The patients complained of vegetative symptoms than somatic symptoms in both bipolar disorder and depressive disorder. Also, the cases of major depression developed more suicide idea symptom while the case of bipolar disorder developed more aggressive symptoms. In the respect of psychotic symptoms, delusion was more frequently shown in major depression, but halucination was more often shown in bipolar disorder. 4) Anxiety disorder coexisted most frequently in two groups. And there coexisted symptoms such as somartoform disorder, mental retardation and personality disorder in both cases. 5) The influence of family loading was remarkable in both cases. Above all, the development of major depression had to do with child abuse history and inappropriate care of family. It is apparent that there are distinctive differences between major depression and bipolar disorder in child and adolescent through the study, just as in adult cases. Therefore the differences of clinical characteristics between two disorders is founded in coexisting disorders and clinical symptoms including onset age, somatic symptoms and vegetative symptoms.
