Factor Structure of the Center for Epidemiologic Studies Depression Scale in South Korea
Open Journal of Medical Psychology, 2014
Results of previous studies from North America reported that only 14 out of the 20 items from the Center for Epidemiologic Studies Depression Scale (CES-D) were required to assess negative affect, somatic symptoms, and anhedonia. However, it remains unclear whether this three-factor structure of the CES-D would be valid in South Korea. The purpose of this study is to examine the validity of the three-factor structure with a Korean version of the CES-D. The participants were Korean college students (N = 215), elementary school teachers (N = 234), and parents of elementary school students (N = 230). Confirmatory factor analysis was performed to examine the scale's validity. Results indicated that the three-factor structure showed acceptable fit to data (comparative fit index = 0.95; root mean square error of approximation = 0.06). The findings indicated that the three-factor structure of the CES-D was valid in South Korea.

Although major depressive disorder (MDD) has a variety of symptoms beyond the affective dimensions, the factor structure and contents of comprehensive psychiatric symptoms of this disorder have rarely been explored using the 18-item Brief Psychiatric Rating Scale (BPRS). We aimed to identify the factor structure of the 18-item BPRS in Korean MDD patients. A total of 258 MDD patients were recruited from a multicenter sample of the Clinical Research Center for Depression of South Korea study. Psychometric scales were used to assess overall psychiatric symptoms (BPRS), depression (Hamilton Depression Rating Scale), anxiety (Hamilton Anxiety Rating Scale), global severity (Clinical Global Impression of Severity Scale), suicidal ideation (Scale for Suicide Ideation), functioning (Social and Occupational Functioning Assessment Scale), and quality of life (World Health Organization Quality of Life Assessment-abbreviated version). Common factor analysis with oblique rotation was used to yie...

Objectives-To estimate the prevalence and identify the predictors of depression among community-dwelling Korean American elderly (KAE). Design-A cross-sectional descriptive epidemiological survey using a two-step sampling strategy to obtain a representative community sample. Setting-We recruited study participants at religious, service, and business establishments in the KA community (26 churches, 6 senior centers, 2 medical daycare centers, 1 supermarket). Participants-Community-dwelling first-generation KAE (n=1,118; mean age ±SD; 70.5 ±7.0 years; female: 67.2%). Measurements-Trained bilingual nurses and community health workers interviewed participants face-to-face for demographic information, chronic conditions, and depression using the Korean versions of the Patient Health Questionnaire (PHQ-9K). Results-30.3% of KAEs were classified as having either mild (PHQ-9K score = 5 to 9; n=218, 19.5%) or clinical depression (PHQ-9K score >=10; n = 120, 10.8%), respectively. One of seven KAE (n=164, 14.7%) endorsed thoughts of death or self-injury, but only 63 (5.7%) reported utilizing mental health services. We also identified several predictors of depression, including living arrangement (living alone vs. living with family/spouse); having chronic conditions such as

Purpose A number of studies suggest that depression is associated with the significant disability and the poorer subjective quality of life (QOL). We aimed to assess subjective QOL in Korean patients with depression and explore the factors (sociodemographic characteristics and clinical features) associated with subjective QOL. Methods We obtained the data from 808 depressive patients who entered the Clinical Research Center for Depression (CRESCEND) study and evaluated the relationship between subjective QOL and personal sociodemographics, and various clinical features, including depressive severity, and subjective QOL. We assessed subjective QOL using the 26-item abbreviated version of the World Health Organization Quality of Life (WHO-QOL-BREF) instrument. Results Decrements in patients' physical health, psychological health, social relationships, and environment domains of subjective QOL were all strongly associated with the greater depressive symptom severity. After controlling for age and depressive symptom severity, the lower subjective QOL was independently related to being divorced or separated, the less monthly household income, and having no religious practices. Conclusion Our results suggest the importance of sociodemographic characteristics in addition to symptoms for the understanding of subjective QOL in depressed patients. The prospective studies to compare the different treatments' effects on various subjective QOL domains are needed.

The Clinical Research Center for Depression (CRESCEND) study is a 9-year observational collaborative prospective cohort study for the clinical outcomes in participants with depressive disorders in Korea. In this study, we examined the baseline characteristics of the depressive participants as the hospital-based cohort. Participants were assessed using various instruments including the Clinical Global Impression scale, 17-item Hamilton Depression Rating Scale (HDRS-17), Hamilton Anxiety Rating Scale, Brief Psychiatric Rating Scale, Social and Occupational Functioning Assessment Scale, Beck Depression Inventory-Second Edition, Scale for Suicide Ideation, and World Health Organization Quality of Life assessment instruments-abbreviated version. Also, personal histories of medical and psychiatric illnesses and the range of socio-epidemiologic and clinical data were collected from each participant. One thousand one hundred eighty three participants were recruited from 18 hospitals. The me...
Depressive Symptoms and Depression Literacy Among Korean Americans
2019
Summary: This study investigated the prevalence of depressive symptoms among Korean Americans (KAs) and its association with depression literacy and their socio-demographic characteristics. Overall, there was a high prevalence of depression among the KAs, and English proficiency and depression literacy were found to be closely related to depressive symptoms among KAs. Content Outline: Depression is considered to be one of the most frequent mental disorders in the US population (Baumeister & Harter, 2007), and depression literacy is a specific type that varies among populations. Especially many Asian Americans (AAs) who view depressive symptoms as a sign of weakness or lack of discipline and willpower (Leong & Lau, 2001); they tend not to accept the medical model of depression (Karasz, 2005). This study investigated the prevalence of depressive symptoms among Korean Americans (KAs) and its association with depression literacy and their socio-demographic characteristics. A sample of c...
Prevalence of major depressive disorder in the general population of South Korea
Journal of Psychiatric Research, 2006
Introduction: Previous epidemiological studies have reported a high prevalence of major depressive disorder (MDD) in North America and Western Europe. However, little information exists on MDD in Asian countries. This study investigates the prevalence of MDD and its characteristics in the general population of South Korea.

Objective: The Depression in Old Age Scale (DIA-S) is a new screening tool for assessing depression in the elderly. The primary aims of this study were to describe the validation of the Korean version of the DIA-S (K-DIA-S) and to compare its validity with that of other depression screening questionnaires used in elderly outpatients in medical settings. Methods: A total of 385 elderly outpatients completed the K-DIA-S and underwent the Mini International Neuropsychiatric Interview to diagnose depressive disorders. Other measures included the 15-item short form of the Geriatric Depression Scale (SGDS), the 9-item depression module of the Patient Health Questionnaire (PHQ-9), and the Montgomery-Asberg Depression Rating Scale (MADRS). Reliability and validity tests, an optimal cutoff point estimate, and receiver operating characteristic curve analysis were performed to investigate the diagnostic validity of the K-DIA-S. Areas under the curves (AUCs) for the K-DIA-S, SGDS, and PHQ-9 were compared statistically. Results: The K-DIA-S showed good internal consistency and strong correlations with the SGDS (r = 0.853), PHQ-9 (r = 0.739), and MADRS (r = 0.772). The cutoff point of the K-DIA-S that can be recommended for screening depressive symptoms was a score of 4. For "any depressive disorder", the AUC (standard error) for the K-DIA-S was 0.896 (0.015), which was significantly larger than that for the PHQ-9 (p = 0.033). Conclusion: The present findings suggest that the K-DIA-S has good psychometric properties and is a valid and reliable tool for assessing depressive symptoms in elderly populations and medically ill patients.

We aimed to investigate the prevalence and psychosocial and neurophysiological correlates of depression in a large county-based cohort of Korean adults. We recruited 2355 adults from a rural county-based health promotion program. The following psychometric scales were used: the Center for Epidemiologic Studies Depression scale (CES-D) was used to assess depression, the General Health Questionnaire (GHQ) was used to evaluate stress, and the Medical Outcome Study Social Support Survey (MOS-SSS) was used to determine perceived social support. Heart rate variability (HRV) was used to assess neurophysiological properties. The psychosocial and neurophysiological variables of adults with depression (CES-D score ≥25) and without depression (CES-D score <25) were statistically compared. A logistic regression model was constructed to identify factors independently associated with depression. We estimated that 17.7% of the subjects had depression, which was associated with old age, being fe...
