    ABSTRACT: Patients with chronic obstructive pulmonary disease (COPD), which is predicted to be the third most common cause of death worldwide by 2020, often suffer from depression, one of the most common and modifiable comorbidities of COPD. This study assessed the prevalence of depression in patients with COPD and the association of depression with disease severity. This was a multicenter, prospective cross-sectional study of 245 patients with stable COPD. Disease severity was assessed using two scales: the global initiative for chronic obstructive lung disease (GOLD) stage and BODE index. Depression was measured using the Centers for Epidemiologic Studies Depression (CES-D) scales. Data were analyzed using descriptive statistics, Spearman correlation, and multivariate logistic regression. Depression defined as a CES-D score of 24 and higher was observed in 17.6 % of patients with COPD. The prevalence of depression increased with disease severity based on the BODE quartile (r = 0.16; P = 0.014). By contrast, no difference was observed in the prevalence of depression among the severity groups using the GOLD staging system (r = - 0.01; P = 0.898). Elementary school graduates were more likely to experience depression than graduates of high school and above [odds ratio (OR) = 3.67; 95 % confidence interval (CI) 1.37-9.85] and patients in BODE quartile II were more likely to experience depression than those with BODE quartile I (OR = 2.5; 95 % CI 1.04-6.06). Depression was associated with disease severity according to the BODE quartile in patients with COPD. BODE quartile II was a significant predictor of depression. Screening patients with a high risk of depression and proactive intervention for those patients are needed.

    ABSTRACT: The purpose of this study was to identify the turnover intention of graduate nurses in South Korea and to explore the correlates of turnover intention. A descriptive, correlational design was used. The participants comprised 225 female nurses who were working at 13 general hospitals and who had accumulated <12 months of clinical nursing experience since their graduation. The data were collected through a structured questionnaire that was conducted from 5-31 August 2009. The mean score for turnover intention was 7.51. Turnover intention was found to be related to the number of beds in the hospital, workplace, and duration of job orientation (theory and practice), instruction by a preceptor, job stress, clinical competence, self-efficacy, and the practice environment. In the multivariate approach, the practice environment, job stress, and the workplace were found to be significantly related to turnover intention and accounted for 36% of the said intention in the studied graduate nurses. The results support that the characteristics of magnet hospitals that improve the practice environment could play a critical role in retaining nurses in hospitals. Managerial interventions that enhance the practice environment, reduce job stress, and place graduate nurses in nursing units with a single specialty could benefit the hospitals employing such nurses. Further research to explore the effects of managerial strategies on graduate nurses' turnover intention is warranted.

    ABSTRACT: The goal of this study was to examine the unique contributions of sleep disturbance to depression in patients with chronic obstructive pulmonary disease (COPD) after controlling for other contributing variables, including patient characteristics, self-efficacy, and physical activity. One hundred thirty-one outpatients diagnosed with COPD from 3 hospitals in South Korea participated in the study. Data were collected from March to June 2010 and analyzed with descriptive statistics, Pearson correlation, and hierarchical multiple regression using the SPSS WIN program. The level of depression reported in this study was 13.84. Sleep disturbance, not living with a spouse, and self-efficacy were all predictors of depression and accounted for 45% of the variance. These findings show the need to screen routinely for sleep disturbance in patients with COPD and support potential benefits of interventions to enhance self-efficacy and quality of sleep in reducing depression in COPD patients.

    ABSTRACT: The purpose of this study was to investigate the prevalence of depression among school girls in Korea and identify factors influencing the tendency to depression. A self-report survey was conducted with South Korean middle schoolgirls who were in the 8th and 9th grades. Four hundred and one schoolgirls were included in the study. The instruments utilized in this study were the Center for Epidemiologic Studies - Depression Scale and Social Problem Solving Inventory-Revised. Data were analyzed using descriptive statistics, Pearson correlation and multiple logistic regression with SPSS WIN 14.0 program. The average depression score of the participants was 20.68, which indicates moderate levels of depression. About 35% of the schoolgirls in this study reported a tendency to depression. Significant predictors for depression were 'decreased problem-solving abilities', 'no family members with whom they can discuss their concern', 'decreased satisfaction in relationship with friends', and 'increased negative self-perception of body-image'. The study findings suggest that schoolgirls require special concern regarding the risk of developing depression. Regular depression screening could be beneficial for early detection of depression in schoolgirls and enhancing problem-solving ability could be considered as an effective strategy to reduce the risk of depression among schoolgirls.
