Objectives: ：This study aimed to examine the mediating effect of sleep quality and interpretation bias for ambiguity in the relationship between hopelessness and suicidal ideation in psychiatric patients. Methods: ：A total of 231 psychiatric outpatients and inpatients completed the Beck Hopelessness Scale, Pittsburgh Sleep Quality Index, Ambiguous/Unambiguous Situations Diary-Extended Version, and Ultra-Short Suicidal Ideation Scale. Data analysis was conducted using regression analyses and bootstrap sampling. Results: ：The results of this study showed that hopelessness had a direct effect on suicidal ideation, and that sleep quality and interpretation bias for ambiguity mediated the association between hopelessness and suicidal ideation. Moreover, there was a significant double mediating effect of sleep quality and interpretation bias for am-biguity on the relationship between hopelessness and suicidal ideation. Conclusions ：These results suggest that it is important to consider both sleep quality and interpretation bias for ambiguity to prevent hopelessness from leading to suicidal idea. These results suggest that considering both sleep quality and interpretation bias for ambiguity may be important in preventing hopelessness from leading to suicidal ideation.

Background: This study aims to delineate the characteristic features of adjustment disorder (AjD) from those of posttraumatic stress disorder (PTSD) and assess the discriminant validity of Diagnostic and statistical manual of mental disorders (DSM)-5 PTSD measures by comparing self-reported data from an outpatient cohort. Methods: The study participants included psychiatric outpatients at a university-affiliated hospital in South Korea.Psychological assessments comprised the Post-Traumatic Stress Disorder Checklist for DSM-5, the National Stressful Events Survey-PTSD Short Scale, the Beck Depression Inventory-II, the Beck Anxiety Inventory, the Insomnia Severity Index, and the Short Form-8 Health Survey. Results: A total of 149 responses (51 participants with AjD and 98 with PTSD) were analyzed. It was observed that workplace conflict was the most common stressor among AjD patients (29%), while traffic accidents were the primary trauma source for PTSD patients (39%). Individuals with AjD reported significantly lower levels of PTSD, depression, anxiety, and insomnia symptoms, along with a higher quality of life. After controlling for educational level as a covariate, the differences in PTSD and depressive symptoms remained significant. Conclusion The findings of this study support the discriminant validity of DSM-5 PTSD measures for AjD and reinforce the notion that that AjD represents a milder form within the stress response spectrum.

OBJECTIVES: This study sought to determine ethnic difference in physical violence and to see if ethnicity is an independent predictor of violence by surveying eight Korean or Han ethnic elementary schools in Yanji city, China. A total of 2,316 school children from fourth through sixth grade participated the study. METHODS: Participants completed a questionnaire on sociodemographic background and experiences of physical violence during the previous year using the Conflict Tactics Scale. The history of physical violence was categorized as within the family, by peers, or by teachers. RESULTS: Han children reported significantly higher rates of physical abuse compared with Koreans (76.2% vs. 54.9%, chi2=116.12, df=1, p=<.001). Binary logistic regression analysis identified five risk factors for physical violence:(1) ethnic Han (odds ratio [OR]=3.01, 95% confidence interval [CI]=2.47-3.66), (2) boys (OR=2.76, 95% CI=2.28-3.36), (3) poor economic status (OR=1.69, 95% CI=1.17-2.42), (4) single or absent parents (OR=1.42, 95% CI=1.09-1.86), (5) interaction of fourth-graders with promotive or neutral opinions of corporal punishment (OR=2.41, 95% CI=1.86-3.13). Ethnicity remained an independent risk factor after other sociodemographic variables were controlled. CONCLUSION: These findings showed cross-cultural risk factors of child physical abuse, including ethnicity which previously identified as a factor in literature. This study particularly reports lower prevalence of physical violence in ethnic minority, Korean-Chinese, compared with the Han ethnic group. This result explained a special environment of Korean self-government district and the successful adaptation of the ethnic minority to the mainstream culture.

OBJECTIVES: This study investigated the psychosocial factors and clinical symptoms related to the duration of untreated psychosis (DUP) in 35 consecutive first-episode inpatients with schizophrenia. METHODS: Data from 35 schizophrenic patients were obtained from two general psychiatric inpatient units at a university medical center. These data included scores from Index of Social Position (ISP), Positive and Negative Syndrome Scale (PANSS) and Symptom Checklist-90-Revised (SCL-90-R) as well as socio-demographic informations. RESULTS: Among socio-demographic variables, lower social position (r=.610, p<.001), male sex (r=.407, p=.015), and grew up in rural area (r=.335, p=.045) were significantly correlated with DUP. The interpersonal sensitivity of SCL-90-R was the only symptomatic variable significantly correlated with DUP (r=.379, p=.027). However, after controlling interactive effects of the variables, only lower social position and interpersonal sensitivity remained significant. Lower social position was more influential on DUP than interpersonal sensitivity in the multiple regression model. CONCLUSION: Both social and symptomatic factors independently influenced DUP in schizophrenic patients. Lower social position defined by education and occupation of patients or caretakers may reflect barriers to psychiatric services or poor identification of mental illness. This together with patients' subjective distress in interpersonal interactions may delay the intervention of psychiatric services.

The Illness Intrusiveness Rating Scale (IIRS) measures illness-induced disruptions to 13 domains of lifestyles, activities, and interests. A stable three-factor structure has been well documented; however, the cross-cultural validity of this scale needs to be tested. This study investigated the factor structure of the Korean version of IIRS in 712 outpatients at a university medical center. A predominant diagnosis of the patients was rheumatoid arthritis (47%). The Center for Epidemiological Studies-Depression Scale (CES-D), and Health Assessment Questionnaire (HAQ) were also administered. Exploratory Principal Component Analysis identified a two-factor structure, "Relationships and Personal Development (RPD)" and "Instrumen-tal", accounting for 57% of the variance. Confirmatory analyses extracted an identical factor structure. However, a goodness-of-the fit test failed to support two-factor solution (X2 =138.2, df=43, p<.001). Two factors had high internal consistency (RPD, alpha=.89; Instrumental, alpha=.75) and significantly correlated with scores of HAQ (RPD, r=.53, p<.001; Instrumental, .r=44, p<.001) and CES-D (RPD, .r=55, p<.001; Instrumental, .r=43, p<.001). These findings supported construct validity of the Korean version of IIRS, but did not support cross-cultural equivalence of the factor structure.

The print media is still one of major sources for health-related information. To shed light on how the media accurately delivers information for post-traumatic stress disorder (PTSD), we searched the newspaper articles and analyzed their contents for accuracy in the description of symptoms, causes, and treatment of PTSD. The articles featuring PSTD were searched from the very first available to 2010 at on-line search systems of three major Korean newspapers. A total of 123 articles appeared and the first article appeared in 1984. The number of articles steadily increased till the early 2000s but we found the robust increase in the late 2000s. Among the mentioned symptoms of PTSD: re-experience (39%) was most common, followed by avoidance or numbing (28%) and hyperarousal (22%). Of the 29 articles mentioning treatment of PTSD, 13 mentioned psychotherapy only and 11 mentioned both psychotherapy and medication equally. However, the psychotherapies mentioned were non-specific and only five articles mentioned any empirically supported therapies. The number of articles on PTSD in Korean newspapers has continually increased during the last three decades. However, the quality of information on the treatment of PTSD was questionable.
