Purpose: The aim of this study was to explore the association between psychosocial work environments and depressive symptoms among Korean registered nurses. Methods: The study population of 331 registered nurses was derived from the 2014 Korean Working Condition Survey (KWCS). Depressive symptom was assessed using the WHO-5 wellbeing index. Results: The thirty-five percentage of Korean registered nurses reported the risk for depressive symptom. Korean nurses with higher 'work-family conflict' were more likely at the risk of depression almost 1.83 (95% CI 1.04~3.20) times than their counterpart. Higher 'possibilities for development' were more likely decrease almost 60% of the risk of depressive symptom. Conclusion: Work-family conflict and possibility of development were associated with depressive symptom among Korean registered nurses. We suggest future researches identifying strategies for decreasing work-family conflict and its negative effects.

Objectives The purpose of this study was to investigate the relationships among circadian types, depressive mood and internet addiction and to identify the mediating effect of depressive mood between circadian types and internet addiction in Korean College Students. Methods A total of 2632 participants completed questionnaires, which included the Korean translation of the Composite Scale of Morningness (CSM), the Patient Health Questionnaire (PHQ-9), and the Korean version of the Internet Addiction Test (KIAT). Statistical analyses were done using correlation analysis, analysis of covariance and multiple linear regression. Results The CSM score was negatively associated with the PHQ-9 score (r = -0.226, p < 0.001) and the KIAT score (r = -0.218, p < 0.001). The eveningness group showed higher scores in depressive mood and internet addiction than the morningness group (p < 0.001). Depressive mood showed a partial mediating effect between circadian types and internet addiction (${\beta}=0.255$, p < 0.001). Conclusions Internet addiction was associated with circadian types and depressive mood. These results suggest that depression and circadian rhythm management would contribute to the prevention of internet addiction.

Purpose: The purpose of this study is to examine the association between each phase of the Life Transition Process (LTP) and depressive symptoms among parents of children with Autism Spectrum Disorder (ASD). Methods: Using a cross-sectional study design, data pertaining to LTP and depressive symptoms were collected from 285 parents of children with ASD (101 fathers and 184 mothers). Participants were recruited through the Autism Society of Korea and a counseling center for families of children with ASD. Results: Using a cut-off point of 5 or higher on the Beck Depression Inventory-Short Form, more than half of the parents (53.4%) were deemed depressed; these parents experienced moderate (27.4%) to severe (11.6%) levels of depressive symptoms. A hierarchical multiple regression using the socio-demographic characteristics of children and parents and each phase of the LTP as predictors, found that lower income (${\beta}=-.14$, p=.007) and greater scores for the wandering phase (${\beta}=.59$, p<.001) were significant predictors of greater levels of depressive symptoms. Conclusion: These findings confirm the association between LTP and depressive symptoms for parents of children with ASD, who were found to have a greater risk of depressive symptoms during wandering phase.

Backgrounds: Irregular and unpredictable work schedules have become more common in most societies. The purpose of this study was to investigate the association between unpredictable work schedules and depressive symptoms in Korea. Methods: Data from 34,486 workers who participated in the Korean Working Condition Survey in 2017 were used. Unpredictable work schedules were measured by questions about the frequency of changes in work schedule and limited advanced notice. Depressive symptoms were assessed by a single item asking if the participants had depressive symptoms over the last 12 months. Multivariable-adjusted logistic regression analysis was used to calculate odds ratios (ORs) for high depressive symptoms. Results: The OR for depressive symptoms was significantly higher in the workers with unpredictable work schedules compared to those with predictable work schedules after controlling for age, sex, education, salary, marital status, occupation, contract period, full-time versus part-time, shift work, weekly working hours, and having a child under the age of 18 years (OR = 2.43, 95% confidence interval 1.93-3.07). Conclusion: Unpredictable work schedules were associated with depressive symptoms controlling for the other dimensions of precarious employment in a representative working population in Korea.

In the current study, the effects of living-alone older adults' social participation on their depressive symptoms were assessed. Data of 924 older adults from the Aging Research Panel Survey were analyzed. The results show that the effects of older adults' social participation on depressive symptoms vary depending on the types of social participation and gender. Men attending school or hometown alumni meetings and clan gatherings showed fewer depressive symptoms; women participating in informal social gatherings or organizations for leisure, culture, and sports had fewer depressive symptoms. The results suggest that living-alone older adults' gender and dimensions of social participation should be considered when designing programs and services to reduce their depressive symptoms.

Objectives: This study aimed to examine the relationship between COVID-19-related depressive symptoms and oral health among Korean adolescents. Methods: Data from the 17th Korea Youth Risk Behavior Web-based Survey were used and analyzed by the chi-squared test, and multiple logistic regression analysis was performed using SPSS 21.0. The final study population comprised 54,835 individuals. Results: The rates of toothache, gingival bleeding, tooth fracture, and tooth sensitivity were 21.2, 19.1, 8.7, and 30.6%, respectively. The rates of equal, increased, and decreased COVID-19-related depressive symptoms were 53.4, 36.9, and 9.7%, respectively. The rates of toothache, gingival bleeding, and tooth sensitivity were significantly higher (49.0, 48.3, and 46.3%, respectively) in the increased depressive symptom group than that in the decreased depressive symptom group (7.7, 8.1, and 7.7%, respectively). After adjusting for gender, school grade, school record, household economic status, tooth brushing frequency, smoking habit, and alcohol consumption, the risks of toothache, gingival bleeding, and tooth sensitivity in the increased depressive symptom group were symptom group were 1.64 (95% CI: 1.51-1.78), 1.55 (95% CI: 1.43-1.68), and 1.77 (95% CI: 1.65-1.89), respectively. Conclusions: There was a significant increase in oral symptoms in the group with increased depressive symptoms.

Purpose: The purpose of this study was to investigate the relationship between digital literacy and depressive symptoms, as well as the mediating role of social support in this relationship, among older women (60 years and older) in Korea. Methods: This study analyzed data from the User Experience Evaluation Survey, which was conducted by the Ewha Institute for Age Integration Research to improve the accessibility of digital information for older adults research from May to September 2020. Survey data on depressive symptoms, digital literacy, and social support were analyzed using descriptive statistics, Pearson correlation coefficients, and multiple regression. Results: The factors influencing depressive symptoms among older women included work status (B=-.19, p=.01), social support (B=-.17, p<.001), self-rated health (B=-.13, p=.003), and digital literacy (B=-.10, p=.005), which had an explanatory power of 33%. In addition, social support played a mediating role in the relationship between digital literacy and depressive symptoms (B=-.05, SE=.02; 95% CI, -.09 to -.02). Conclusion: The findings of this study support the need to develop and apply interventions that promote digital literacy among older women to mitigate depressive symptoms by increasing social support.

Objectives We conducted a meta-analysis of randomized controlled trials to investigate the therapeutic effects of mindfulness-based interventions on depressive symptoms in patients with major depressive disorder. Methods In February 2021, we searched Embase, MEDLINE, Cochrane Library, PsycINFO, CINAHL, and AMED. Under the guidance of the corresponding author, two evaluators independently reviewed and selected articles based on predetermined selection criteria. Results Based on the selection criteria, we systematically screened and included a total of 12 randomized controlled trials comprising 720 cases for the final analysis. Utilizing a random-effects model for data analysis, we determined the Hedges' g value to be 0.787, indicating a medium-sized effect according to Cohen's interpretation. The 95% confidence interval for the effect size ranged from 0.414 to 1.160 (p-value < 0.0001). Conclusions This study reveals the potential effectiveness of mindfulness-based interventions in treating depressive symptoms among patients with major depressive disorder.

This study aims to classify types of work-life balance among employees using Latent Profile Analysis (LPA) and investigate variations in depressive symptoms and satisfaction with working conditions across these types. Data were derived from the 6th Korean Working Conditions Survey (KWCS), conducted between 2020 and 2021, which included a sample of 49,479 employed individuals. The LPA revealed three distinct profiles of work-life balance: Low Balance (18.5%), Moderate Balance (72.9%), and High Balance (8.6%). Significant differences in depressive symptoms and satisfaction with working conditions were observed among these profiles. Specifically, the Low Balance group exhibited the highest levels of depressive symptoms and the lowest satisfaction with working conditions, while the High Balance group displayed the lowest depressive symptoms and the highest satisfaction. These findings underscore the critical role of work-life balance in influencing both depressive symptoms and job satisfaction among workers.
