Prevalence and Correlates of DSM-IV Mental Disorders in South Korean Adults: The Korean Epidemiologic Catchment Area Study 2011.

Objective: The aim of this study was to estimate the prevalence and correlates of mental disorders in Korean adults.

Methods: Door to door household surveys were conducted with community residents aged 18-74 years from July 19, 2011, to November 16, 2011 (n=6,022, response rate 78.7%).

Impact of childhood exposure to psychological trauma on the risk of psychiatric disorders and somatic discomfort: single vs. multiple types of psychological trauma.

We examined whether childhood exposure to multiple types of potentially traumatic events (PTEs) relative to a single type of PTE is associated with a higher prevalence of psychiatric disorders and greater somatic discomfort in Korean adults. The Composite International Diagnostic Interview 2.1 (K-CIDI 2.

Prevalence, correlates, and comorbidities of four DSM-IV specific phobia subtypes: results from the Korean Epidemiological Catchment Area study.

Although several studies have detected differences in clinical features among specific phobias, there is a shortage of detailed national data on the on the DSM-IV SP subtypes, particularly in the Asian population. To examine the prevalence, demographic and other correlates, and co-morbidities of DSM-IV SP subtypes in a nationwide sample of Korean adults. We recruited 6510 participants aged 18-64 years for this study.

Validation of the Korean version of the Eppendorf Schizophrenia Inventory as a screening measure to detect adolescents at ultra-high risk for psychosis.

Aim: No validated self-report scale is available for use as a screening tool to detect non-help-seeking adolescents at ultra-high risk (UHR) for psychosis in a community setting. The study aims to examine the reliability and validity of the Korean version of the Eppendorf Schizophrenia Inventory (K-ESI) for assessing adolescents at UHR for psychosis in a community setting.

Methods: In the first study, to confirm the reliability and discriminant validity of the K-ESI, community sample (782 adolescents, 281 young adults, 122 early and middle-aged adults) and outpatients with schizophrenia (109) were recruited.

DSM-IV psychiatric comorbidity according to symptoms of insomnia: a nationwide sample of Korean adults.

Purpose: The diagnosis of insomnia is based on the presence of four different symptoms: difficulty in initiating sleep (DIS), difficulty in maintaining sleep (DMS), early morning awakening (EMA), and non-restorative sleep (NRS). This study investigated the differences in sociodemographic correlates and psychiatric comorbidity between the four symptoms of insomnia in the general population of South Korea.

Methods: A sample of the population aged 18-64 (N = 6,510) was questioned using a face-to-face interview.

Lifetime risk and age of onset distributions of psychiatric disorders: analysis of national sample survey in South Korea.

Background: The present study represents the first attempt at examining variation across Korean cohorts with respect to lifetime risk of DSM-IV psychiatric disorders.

Aims: To present data on lifetime prevalence and projected lifetime risk, as well as age of onset (AOO) and demographic correlates of DSM-IV psychiatric disorders as assessed in the nationwide survey of a representative sample of Korean adults.

Method: The survey was based on a multistage area probability sample of non-institutionalized Koreans aged 18-64 years.

Prevalence of DSM-IV major mental disorders among Korean adults: A 2006 National Epidemiologic Survey (KECA-R).

Objectives: The aim of this study was to estimate the prevalence of the DSM-IV major mental disorders in the Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI).

Methods: The Korean Epidemiologic Catchment Area study Replication (KECA-R) was conducted between August 2006 and April 2007. The sampling of the subjects was carried out across 12 catchment areas using a multistage, cluster sampling design.

Service priority and standard performance of community mental health centers in South Korea: a delphi approach.

Objective: The role of community mental health centers (CMHCs) in Korea is quite different than that of these centers in Western countries due to nation-specific health care system characteristics. For example, CMHCs of Korea are expected to provide services for serious mental illness in addition to other services in response to community needs, such as internet addiction of adolescents. Consequently, it is important to determine service priorities of CMHCs and to define standard service performances in order to maximize their effectiveness with limited resources.

Obovatol enhances docetaxel-induced prostate and colon cancer cell death through inactivation of nuclear transcription factor-kappaB.

Nuclear transcription factor-kappaB (NF-kappaB) is constitutively activated in prostate and colon cancers and is related with the resistance of cancer cells against chemotherapeutics. Previously, we found that obovatol, an active compound isolated from Magnolia obovata, inhibited cancer cell growth through inhibition of NF-kappaB activity. We investigated here whether obovatol could sensitize cancer cells against docetaxel through inhibition of NF-kappaB activity in prostate cancer (LNCaP and PC-3) and colon cancer (SW620 and HCT116) cells.

Determinants of length of stay for psychiatric inpatients: analysis of a national database covering the entire Korean elderly population.

Objective: In a rapidly aging society, inappropriately long geropsychiatric inpatient hospitalization is a challenging concern for mental health policy-makers and researchers. This study aimed to investigate patient and institutional factors affecting geropsychiatric inpatient length of stay (LOS), providing an overview of current geropsychiatric health care system in South Korea.

Methods: This retrospective, population-based, cross-sectional study analysed nationwide reimbursement claim databases covering the entire elderly population of Korea between January 2005 and June 2006.
