RESUMO
Background@#Information about the factors involved in the progress of both high distressed and low distressed victims in the early days after a sexual assault are needed to provide effective intervention for victims of sexual assault. In this study, we examined the relationship among posttraumatic stress disorder (PTSD) symptoms, assault-related factors and trauma-related cognitions in Korean female victims of sexual assault. @*Methods@#For this study, we retrospectively investigated the records of 94 female victims from the Sunflower Center for Women and Children Victims of Violence at the Ajou University Hospital in Korea. Demographic characteristics and the features of the sexual assault, post-traumatic stress symptoms, and trauma-related cognition were obtained from data recorded at the initial assessment. One month after the initial assessment, victims were contacted by telephone and their PTSD symptom severity was re-evaluated. The sample of 94 participants were divided into two groups depending on the PTSD symptom scale scores at initial assessment: High-distress group and Low-distress group. @*Results@#Repeated-measured analyses of variance revealed that the high-distress group showed a decrease in PTSD symptom severity over the month, while the low-distress group did not show significant change of PTSD symptom severity. In correlation analysis, negative thoughts and beliefs about the assault were strongly correlated with PTSD symptom severity one month later in both the low-distress and high-distress groups. @*Conclusion@#Our results suggest that trauma-related cognitions seem to play an important role in the maintenance of PTSD both of high-distress and low-distress groups, and that effective intervention will need to address these cognitive factors.
RESUMO
More than half of all sexual assault victims report experiencing sexual victimization more than once. The aim of this paper was to determine the role post-traumatic cognition plays in the relationship between a history of sexual abuse and post-traumatic stress symptoms in sexual assault victims. The relationship between a history of sexual assault and the severity of post-traumatic stress symptoms was investigated retrospectively using data from a sexual assault crisis center in Korea. Data on psychological symptoms were collected in person at the initial assessment and by telephone 1 month later using the Post-traumatic Cognitions Inventory and the Post-traumatic Stress Disorder Symptoms Scale: Self-report Version. Of 105 women included in the analysis, 10 (9.5%) reported prior sexual abuse and were classified as sexually revictimized. Revictimized women had more post-traumatic negative cognition at initial assessment (t = −2.98; P = 0.004) and more post-traumatic symptoms at 1 month follow-up (t = −2.39; P = 0.019) than singly victimized women. At 1 month follow-up, the severity of post-traumatic stress symptoms had increased in revictimized women but had decreased slightly in singly victimized women. Negative post-traumatic cognition fully mediated the association between a history of sexual abuse and the severity of post-traumatic stress symptoms. Early detection of sexually revictimized women and tailored service and treatment intervention is needed to better serve this group of victims. Interventions targeted at preventing revictimization or post crime victimization may also help victims recover from the trauma and prevent future abuse.

OBJECTIVE: Peer relationships are one of the important factors in children's development. The present study examines the relationship between the effects of early peer relationships and adolescent psychological adjustment. METHODS: The first survey took place from 1998 to 2000, and a follow-up assessment obtained data in 2006, as the original participants reached 13-15 years of age. The first assessment used the Korean version of the Child Behavior Checklist (K-CBCL) and simple questions about peer relationships to evaluate the participants. The follow-up assessment administered the Korean Youth Self Report (K-YSR). RESULTS: Children's peer relationships have longitudinal effects on mental health and adjustment. Children who had qualitative peer-relation problems were more likely to exhibit internalizing problems as adolescents. CONCLUSION: Children who have poor peer relationships might become more vulnerable to emotional problems and social adjustment as adolescents.

OBJECTIVE: We aimed to evaluate the psychometric properties of Korean version of Ruminative Response Scale (K-RRS) for Korean adolescents. METHODS: A community sample of 1220 adolescents was recruited from middle schools and high schools. Exploratory factor analyses and confirmatory factor analyses were conducted, and additional analyses were performed to assess the reliability and validity of the K-RRS. RESULTS: An exploratory factor analysis of a sample of adolescents (n=550) yielded a three factor structure: 'depressive rumination', 'reflective pondering', and 'brooding'. Confirmatory factor analyses of another sample of adolescents (n=530) supported the three-factor model for the K-RRS. The K-RRS was found to have good internal consistency and construct validity. CONCLUSION: Our results suggest that K-RRS is a valid measurement to assess rumination in adolescents, as well as in adults.

This study prospectively examined the relationships among cognitive factors and severity of Posttraumatic stress disorder (PTSD) symptoms in female victims of sexual violence. Thirty-eight victims of sexual violence recruited from Center for Women Victims of Sexual and Domestic Violence at Ajou University Hospital. Cognitive factors and PTSD symptom were assessed within 4 months of sexual violence and 25 victims were followed-up 1 month after initial assessment. Repeated-measured ANOVA revealed that PTSD incidence and severity decreased over the month (F [1, 21]=6.61). Particularly, avoidant symptoms might decrease earlier than other PTSD symptoms (F [1, 21]=5.92). This study also showed the significant relationship between early negative trauma-related thoughts and subsequent PTSD severity. Shame and guilt proneness had significant cross-sectional correlations with PTSD severity, but did not show associations when depression severity is controlled. Our results suggest that avoidant symptoms might decrease earlier than other PTSD symptoms during the acute phase and that cognitive appraisals concerning the dangerousness of the world seem to play an important role in the maintenance of PTSD (r=0.499, P<0.05).

OBJECTIVES: The objective of this study was to assess the characteristics of smartphone use in elementary school children and the emotional and behavioral problems associated with smartphone overuse and addiction. METHODS: Children referred to a community based pediatric mental health center were screened for smartphone addiction and related problematic behavior using the Smartphone Addiction Proneness Scale and the Korean version of the Child Behavior Checklist (CBCL). RESULTS: 1) Statistically significant differences in gender, usage time, ownership, and internalization symptoms (somatization, anxiety/depression, withdrawal) were observed between the smartphone excessive user group and the control group. 2) Variants showing the most significant correlation with smartphone addiction were usage time, internalization problems somatization, anxiety/depression, withdrawal, aggressive behaviors, and total behavior problems. CONCLUSION: The results of this study indicated an association of addiction tendency in elementary school children with internalization symptoms. Close observation in the familial and academic setting may be important for children at high risk for smartphone addiction.

OBJECTIVE: The aim of this study was to examine the prevalence of Internet addiction in middle school students and to identify associated psychosocial risk factors and depression. METHODS: This study was part of a larger epidemiological study on childhood psychiatric disorders conducted in Osan, a city of Republic of Korea. We used IAS for internet addiction, K-YSR for subjects' emotional and behavioral problems and K-CDI for depressive symptoms. We used the data of n=1217 completed cases. We put on independent variables, which are sex, age, smoking and alcohol experiences, economic status, age of first Internet use, K-YSR and K-CDI score. RESULTS: The subjects consisted of addicted users (2.38%), over users (36.89%) and normal Internet users (60.72%). Attention problems, sex, delinquent problems, K-CDI scores, thought problems, age and aggressive behavior were predictable variables of internet addiction. Age of initial Internet use negatively predicted Internet addiction. CONCLUSION: This result showed similar to other researches about sociodemographic, emotional or behavioral factors related to internet addiction. Generally, subjects with more severe internet addiction had more emotional or behavioral problems. It means that they already have had various difficulties when we found internet addiction of adolescents. Therefore it is necessary to evaluate whether the subjects have any emotional or behavioral troubles and to intervene to prevent internet addiction.

Depression during adolescence is critical to the individual's own development. Hence, identifying individuals with high-risk depression at an early stage is necessary. This study aimed to identify childhood emotional and behavioral risk factors related to depressive symptoms in Korean adolescents through a longitudinal study. The first survey took place from 1998 to 2000, and a follow-up assessment conducted in 2006, as the original participants reached 13-15 yr of age. The first assessment used the Korean version of Child Behavior Checklist and a general questionnaire on family structure, parental education, and economic status to evaluate the participants. The follow-up assessment administered the Korean Children's Depression Inventory. Multiple regression analysis revealed that childhood attention problems predicted depressive symptoms during adolescence for both boys and girls. For boys, family structure also predicted adolescent depressive symptoms. This study suggests that adolescents with attention problems during childhood are more likely to experience depressive symptoms.

BACKGROUND: Surgical correction of patent ductus arteriosus (PDA) is relatively safe and effective since it does not remain in the category of open-heart-surgery. Although the surgical practice for PDA is performed in almost all hospitals, they contain the problems of anxiety of patients, remained surgical wounds on patients' chests and complications of surgery and general anesthesia. Recently non-surgical methods for the obstruction of PDA have been developed and some of them including buttoned devices are used now. The success rates of these methods approach to 84%. But the problems of embolization, incomplete closure, hemolysis, stenosis of aorta and left pulmonary artery have been reported. We invented new PDA occluder , using stainless steel wire and polyurethane foam. Therefore we investigated the efficacy of occluding blood flow with the new PDA occluder in the vessels of experimental animals. METHOD: Using 304 stainless steel wire which is self-expandable stent, two star-shaped frames were made, each frame forming cone and facing the other's tip. And in the center of the frames polyurethane foam was inserted. 316L stainless steel wire was used to fix the elements described above and some portion of the wire was extracted outside of the frames, shaping hook or round loop with which the occluder could be pulled out in case of misplacement. To create the similar situation to PDA, we made shunts from artery to vein between carotid arteries and jugular veins with surgical bypass grafts or made shunts of direct artery to vein connections without grafts in 4 dogs and 1 pig. Through 8F sheath, we deployed the occluders into the shunts made of 5 grafts or made of 3 arterial ends. Also the occluders were inserted into the femoral artery of dog and iliac artery of pig. After deployment of occluders, angiograms were performed to obscure the efficacy of blocking blood flow and follow-up angiogrms were done in one and two weeks. The animals were sacrificed in one and two weeks to get the tissues including occluders inside. Gross findings were checked about thrombi formation in and around polyurethane foam. RESULTS: The 10 occluders were placed successfully except one site due to misplacement. The occluders successfully blocked the blood flows in all 10 sites within 3 - 60 minutes. Each follow-up angiogram for occluders in one and two weeks revealed good maintenance of blockade in blood flow. Observed gross findings on tissues were packed thrombi formation in the polyurethane foam and membrane formation along the occluder. CONCLUSIONS: This newly developed device revealed good efficacy for occlusion of blood flow including shunts in immediate and follow-up study. Practical method for the delivery of the device and some design modification for proper fitting into the PDA especially for small patients would be required. Longer period of follow-up with more animal experiments for other possible complications including distal embolization would be required also before clinical trial.
