Negative experience related to work-family multiple roles has been associated with internalizing problems in mothers. In particular, employed mothers with preschool children report high degree of stress. As such, the need to examine potential factors that may explain and alleviate such difficulties has been emphasized. The purpose of this study was thus to examine the mediating effect of sociotropy on the relationship between negative work-family multiple roles and internalizing problems in employed mothers with preschool children. The Negative Experience of Work-Family Multiple Roles Scale, Adult Self Report (ASR) Scale, and Personal Style Inventory-II (PSI-II), were completed by 208 employed mothers with preschool children through an online survey. The results indicated that the direct effect of negative experience of work-family multiple roles on internalizing problems was statistically significant and the indirect effect of sociotropy in this relationship was significant. These findings suggest that sociotropy in employed mothers may indirectly explain internalizing problems related to multiple roles. The implications of sociotropy in negative experience of work-family multiple roles and internalizing problems are discussed.

Purpose : The aim of this study was to develop a quality of life scale for children on chronic peritoneal dialysis(QOL-CPD). Methods : Thirty children on chronic PD at Seoul National University Children's Hospital participated. A healthy control group included 47 elementary school children. Other patients groups are 32 children from the department of pediatric orthopedics and 28 children from the department of child psychiatry. The age range of all children was 7 to 16 years. Preliminary items of the QOL-CPD were developed and administered along with the Korean version of the Children's Depression Inventory(CDI) to all children. Results : The final QOL-CPD was constructed by excluding those items with a factor loading of less than .20, and the principal axis factor analysis was performed again. The QOLCPD demonstrated a good internal consistency with a value of .87. The dialysis and childpsychiatric groups showed significantly lower QOL scores compared to the healthy control group. In addition, the dialysis and child-psychiatric groups showed greater difficulties on physical and academic functions. For the CDI, the PD group showed a mild level of depression. Conclusion : The results of this study demonstrate the clinical utility of a newly developed self-report QOL scale specific for children on chronic PD.

There are several candidate genes in genetic study of alcoholism. Among them, allelic associations have been reported between MAOA CA repeat polymorphism and alcohol dependence, recently. And also, several studies have been investigated genotype-phenotype relationships between MAOA CA repeat polymorphism and clinical manifestations. The authors tried to identify differences in allelic frequency of MAOA CA repeat polymorphism between alcohol dependence and controls, and in behavioral trait and clinical characteristics according to MAOA CA repeat polymorphism. We also tried to investigate genotype-phenotype relationships between MAOA CA repeat polymorphism and behavioral trait such as aggression. We examined 49 male patients with alcohol dependence(DSM-IV) who had been admitted in Yong-In Mental Hospital from June 1st 1998 to October 31th 1998. We performed semistructured interview for demographic and clinical characteristics. Self-report questionnaire for BDHI(Buss-Durkey Hostility Inventory) was given to all subject at least 4weeks later after admission. Using polymerase chain reaction and polyacrylamide gel electrophoresis, MAOA CA repeat polymorphism were observed in 52 male controls and 49 male patients with alcohol dependence. We devided alcoholic patients into two groups according to allelic length of MAOA CA repeat polymorphism ; alcoholics with short alleles(${\leq}$119bp, N=20) and alcoholics with long alleles(${\geq}$123bp, N=29). T-test, ${\chi}^2$-test and Fisher exact probability test were used for statistical analysis. There were no significant differences in frequency of each allele and short and long alleles of MAOA CA repeat polymorphism between alcoholics and controls. But there were significant differences in clinical symptoms and behavioral trait between alcoholics with short and long alleles. In clinical symptoms, alcoholics with long alleles used alcohol more frequently during one month before admission, had much more maximum amount of beer drinking and reported withdrawal seizure more frequently than with short alleles. In contrary, alcoholics with short alleles expressed depressed mood and guilty feeling more frequently and wanted complete abstinence as a treatment goal more frequently than with long alleles. In behavioral trait, alcoholics with long alleles had higher total aggression score and showed much more self-assertive attitude(subscale of expression of aggression) than with short alleles. Allelic length of MAOA CA repeat polymorphism was correlated with self-assertive attitude and accounted for 9% of the variance of self-assertive attitude. And also, predictable variables of allelic length of MAOA CA repeat polymorphism were drinking frequency and self-assertive attitude. Our findings suggest that MAOA CA repeat polymorphism may provide some behavior modifying role especially in self-assertive attitude and indirect symptom modifying role in Korean male alcoholics.

Objectives : The aims of this study were to investigate the psychopathology in adolescents with internalizing disorder using the self-report version of Strengths and Difficulties Questionnaire (SDQ-SR) and the Minnesota Multiphasic Personality Inventory for adolescents (MMPI-A), and to explore the complementarity between these two inventories for diagnostic assessment. Methods : Ninety-one patients aged 13-17 were divided into two groups by clinical diagnosis, 44 with internalizing disorder and 47 comparison group with other disorders. The data of SDQ-SR and MMPI-A completed by them were analyzed for the ability to predict internalizing disorder. Results : The logistic regression analysis revealed that diagnostic predictability increased by 2.27 times with every 1 point of SDQ-SR emotional symptom score increment. Comparison of ROC curves for internalizing disorders showed that the SE and SP of SDQ-SR emotional symptom with score over 4 was 88.94 and 78.72, respectively. For A-anx of MMPI-A with score over 56, SE and SP was 77.27 and 74.47, respectively. However, combination of these scales could not enhance the predictability of diagnostic classification more than that of SDQ-SR emotional symptom alone. Conclusions : Emotional symptom scale of SDQ-SR and A-anx, A-aln, A and INTR of MMPI-A should be important subscales for diagnosing the internalizing disorder of adolescents, however, which needs to be examined further with a larger sample size including normal control group.

The purpose of this study was to investigate the visuo-spatial attention ability and the emotional perception ability of people across the normal range of the scores on the bipolar disorder scale. The Korean version of the Mood Disorder Questionnaire (K-MDQ) was used to measure the bipolar disorder tendency of normal people. A useful field of view (UFOV) task and an emotional perception task were used to measure visuo-spatial attention and emotional perception ability, respectively. The participants did not have any mental illness history or other medical problems. The participants were divided into three groups according to K-MDQ score (low, normal, and high), and their performances were compared. In the UFOV task, the high K-MDQ score group had lower level of performance than the other groups, suggesting that a high bipolar tendency is associated with reduction of visuo-spatial attention ability. In the emotional perception task, the group with the high K-MDQ score showed higher perception of negative emotion bias than the other groups, suggesting a high bipolar tendency to associate with reduction of emotional perception ability. These results suggest that visuo-spatial and emotional attention abilities are related with bipolar disorder tendency even in the normal population.

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.

The purpose of this study was to examine the nature of psychopathology and psychosocial environments of children with Atopic Dermatitis(AD) and their relationship to skin symptoms. Seventy outpatients with AD(mean age 9.94, range 4-15 years) and their mothers were subjected to psychiatric interview and parent- and self-report questionnaire(CBCL, MBRI, CDI, Spielberger's State-Trait Anxiety Inventory for Children(STAI), Family Impact questionnaire). Disease severity was assessed in three dimensions(skin extent, disease activity, and subjective symptom) by SCORAD index. Sixteen(22.9%) of our sample were suspected to have behavioral-emotional problems and they were different from non-problem group on depression, trait-anxiety, maternal controlling attitude and negative appraisal of children. While skin inflammation activity was correlated with only trait-anxiety and depression, subjective skin symptoms were correlated with many psychosocial factors such as depression, state-and traitanxiety, family-impact, social competence, internalized and externalized behavioral problem, sexual problem, and mother's positive appraisal of children). We concluded that children with AD are highrisk group for behavioral-emotional problems, and these problems along with maternal negative parenting attitude can affect their subjective symptom experience.

Cancer is the second leading cause of the death in Korea. Family caregivers of dying patients manifest many psychological and physical symptoms of stress, and they often seek for informational support from health care providers. Unfortunately, however, few systematic studies identify the actual effect of such support on family caregivers. This study, thus, intends to evaluate the effect of informational support for hospice care. One group pretest-posttest design was used, employing the stress-coping model by Cohen and Wills as a conceptual framework. This research was conducted from July 1 to November 15, 1998, initially with 32 subjects sampled from hemato-oncology department of two general hospitals in Seoul, but reduced to 18 at the end due to the untimely death of patients or caregiver's refusal during the course of study. Informational supports were programmed to provide the family caregivers with 8 times of education and counseling as well as 24-hour hot-line for 4 weeks. A booklet that explains the various problems of hospice care was also prepared and distributed to all subjects. Data were collected by using self-report questionnaires and reviewing medical records. The tools used in this study were based on the Weinert's PRQ-II(scale of perceived social support), Spielberger's state anxiety inventory, and CES-D. Also included in the data collection were the general characteristics of family caregivers and patients, and the pain intensity and the performance status of patients. The data were analyzed with descriptive statistics, Wilcoxon sign rank test and paired t-test using SPSSWIN program. The results of the study were as follows: 1.The perceived social support of family caregivers was not significantly increased with informational support for hospice care(t=1.64, one tailed p=.060). 2.The anxiety of family caregivers was significantly reduced following informational support for hospice care(t=3.48, one tailed p=.002). 3.The depression of family caregivers was significantly reduced following informational support for hospice care(t=-2.18, one tailed=.022). 4.The pain intensity of patients with terminal cancer was significantly reduced following informational support for hospice care(t=-2.41, two tailed p=.027). The results suggest that the informational support provided to family caregivers of patients with terminal cancer reduced not only their anxiety and depression but also the pain intensity of patients. Further study is necessary to consolidate the conceptual framework of this study with expanded number of subjects. Nevertheless, it was certain that the informational support program for hospice care was very helpful to both caregivers and patients. Thus, the informational support program is strongly recommended for the hospitals which have no hospice unit yet.

Objectives : The $2^{nd}$ to $4^{th}$ digit length(2D : 4D) ratio reflects the amount of exposure and sensitivity to the prenatal sex hormone and it is considered to be the most convenient and useful way to understand the influence of sex hormone in the determination of human behavioral traits. This study was carried out to find the correlation between the 2D : 4D ratio and characteristics of temperament and character in Korean university students. We assumed that 2D : 4D ratio would show a strong correlation with temperament which is defined to be an inclination of an automatical emotional response to a stimulus. Methods : Participants were 104 university students who completed 2 self-report measures : Temperament and Character Inventory(TCI), Temperament Test. We examined the 2D : 4D ratio of each subject by measuring the lengths of the $2^{nd}$ and $4^{th}$ fingers using a photocopy measurement. We performed statistical analyses using correlation test and t-test to examine the relationship between 2D : 4D ratio and psychological characteristics. Results : We found out the typical sex difference in 2D : 4D ratio. Women had significantly higher 2D : 4D ratio than men. TCI-Character factor(TCI-C) didn't show any significant correlation with the 2D : 4D ratio. TCI-Tempterament factor(TCI-T) and the item of Temperament Test showed a significant correlation with the 2D : 4D ratio. In correlation analysis of the total group including all women and men, the 2D : 4D ratio showed a significant positive correlation in a subscale(shyness with stranger) of harm avoidance scales in TCI-T. In correlation analysis of women's group, the 2D : 4D ratio showed a significant positive correlation in two subscales( fear of uncertainty) and[shyness to stranger] of harm avoidance scales in TCI-T. In correlation analysis of men's group, the 2D : 4D ratio showed a significant negative correlation with a sanguine temperament item of the Temperament Test. Conclusion : The results suggest that the amount of exposure to sex hormone in the prenatal period seems to have an impact on the determination of temperament and characteristics.

Objectives: The objective of this study was to investigate the correlation between insufficient sleep and visuospatial memory in adolescents using a computerized neurocognitive function test. Methods: A total of 103 high school students (26 males and 77 females; mean age $17.11{\pm}8.50years$) without a serious psychiatric problem was recruited. All subjects were requested to complete a self-report questionnaire about weekday total sleep time and weekend total sleep time. The epworth sleepiness scale (ESS) and the beck depression inventory (BDI) were administered to measure daytime sleepiness and symptoms of depression. Seven subsets of the Cambridge Neuropsychological test automated battery were examined to assess visuospatial memory. Results: After controlling for age, sex, ESS, and BDI, longer weekend total sleep time was correlated with poor performance on delayed matching to sample (r = -0.312, p = 0.002) and immediate recall on pattern recognition memory (r = -0.225, p = 0.025). Increased weekend catch-up sleep time was correlated with poor performance of delayed matching to sample (r = -0.236, p = 0.018), immediate recall on pattern recognition memory (r = -0.220, p = 0.029), and delayed recall on pattern recognition memory (r = -0.211, p = 0.036) after controlling for age, sex, ESS, and BDI. Conclusion: This study showed that increased weekend catch-up sleep time reflecting insufficient weekday sleep were associated with poor performance in delayed recall tasks of visual memory. This finding suggests that insufficient sleep during adolescence might produce a decline of visuospatial memory.
