Purpose This study aimed to examine whether sleep duration mediated the relationship between adolescent smartphone addiction and depression. Moreover, we investigated whether the mediating effects of sleep duration were moderated by parental smartphone addiction.
Methods Wave 4(2021) data collected in 2021 from the Korean Children and Youth Panel Survey (KCYPS) 2018 was used. The data collected from 4,392 matched pairs of parents and their children was analyzed, using the SPSS PROCESS macro.
Results Sleep duration partially mediated the relationship between adolescent smartphone addiction and depression. Also, parental smartphone addiction moderated the indirect effect of this mediation model.
Conclusion This suggests that it is necessary to include content on the use of smartphones by adolescents as well as their parents when designing education and intervention programs to prevent depression in adolescents.
Purpose Depression and frailty are common health problems that occur separately or simultaneously in later life. The two syndromes are correlated, but they need to be distinguished to promote successful aging. Previous studies have examined the reciprocal relationship between depression and frailty, but there are limitations in the methods or statistical analysis. This study aims to confirm the potential prospective bidirectional and causal relationship between depression and frailty.
Methods We used data from 887 older adults aged 70 to 84 from the Korean Frailty and Aging Cohort Study (KFACS) in 2016, 2018, and 2020 (3 waves). We separated the within-individual process from the stable between-individual differences using the random intercepts cross-lagged panel model.
Results Significant bidirectional causal effects were observed in 2 paths. Older adults with higher depression than their within-person average at T1 had a higher risk of frailty at T2 (β=.22, p=.008). Subsequently, older adults with higher-than-average frailty scores at T2 showed higher depression at T3 (β=.14, p=.010). Autoregressive effects were only significant from T2 to T3 for both constructs (Depression: β=.16, p=.044; Frailty: β=.13, p=.028). At the between-person level, the correlation was significant between the random intercepts between depression and frailty (β=.47, p<.001).
Conclusions We find that depressed older adults have an increased risk of frailty, which contributes to the onset of depression and the maintenance of frailty. Therefore, interventions for each condition may prevent the entry and worsening of the other condition, as well as prevent comorbidity.
Purpose Preventing the effects of physical vulnerability is a practical approach to improving older adults’ depressive symptoms. This study aims to examine the relationship between gender differences related to muscle strength and depressive symptoms mediated by perceived stress.
Methods In this cross-sectional study, data from 2,705 older adults (65 years old or older) from the Korea National Health and Nutrition Examination Survey VII 2016 and 2018 were analyzed. The moderated mediation model was developed; the outcome, independent, mediation, and moderated mediation variables in the literature-based research model were depressive symptoms, muscle strength, perceived stress, and gender, respectively.
Results Perceived stress had a mediating effect on the relationship between muscle strength and depressive symptoms. The indirect effect of muscle strength on depressive symptoms mediated by perceived stress was β = -.02 (95% CI:-0.03~-0.01). The moderated mediation model demonstrated that the interaction term of handgrip strength and gender negatively affected perceived stress, which indicated that gender moderated the mediating model of perceived stress on the association of muscle strength and depressive symptoms (β = -.01, p <.05). The conditional indirect effect model was insignificant in the male group (β = -.00, 95% CI:-0.01~0.01) but significant in the female group (β = -.01, 95% CI: -0.02~0.00). Conclusions: Perceived stress mediated the relationship between muscle strength and depressive symptoms. However, the effect differed by gender. A stress-mediated depressive symptoms intervention program for older adults should be developed to consider women’s needs.
Purpose The purpose of this study is to construct and verify a path model for the factors affecting on quality of life in long-term care insurance in-home service users.
Methods Total 246 participants using long-term care insurance in-home service were recruited from long-term care agencies. Data collection was conducted using a structured questionnaire from March 1st to March 31st 2021. The collected data were analyzed using SPSS 26 and AMOS 26 programs.
Results The hypothetical path model was suitable for explaining the health-related quality of life in long-term care insurance in-home service users and has an explanatory power of 39.8%. Long-term care grade, depression, perceived health status, social support, age and living arrangement had a significant total effect on the quality of life in long-term care insurance in-home service users.
Conclusion Long-term care insurance in-home service policies need to be expanded, such as screening and relieving depression, strengthening social support, and fostering a positive perception of health to improve the quality of life of the elderly.

Purpose The purpose of this study was by understanding the correlation between the depression, social support and self-care of tuberculosis patients and by identifying the factors that influence the self-care.
Methods: The study subjects were 119 outpatients who were diagnosed with pulmonary and respiratory tuberculosis at a university hospital in D city. The survey questions measured depression, social support, self-care. Using the SPSS/WIN 23.0 program, the collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlations and multiple regression analysis.
Results: As a result of correlation analysis, there was a statistically significant negative correlation between self-care and depression (r=-.53, p<.001), and there was a significant positive correlation between self-care and social support (r=.68, p<.001). Factors affecting self-care of the subjects were social support (β=.51, p<.001), depression (β=-.32, p<.001), drug discontinuation experience (β=-.30, p<.001) and drug resistance (β=-.14, p<.001). These factors explained 62% of the variance.
Conclusion: In order to improve the self-care ability of tuberculosis patients, it is necessary to develop education and nursing intervention programs that can lower patients' depression and strengthen social support.

Purpose The aims of this study were to examine the rate of depression among older adults living alone and to identify factors associated with depression in older adults living alone during the COVID-19 pandemic.
Methods: A secondary data analysis was performed using data from the 2020 Korea Community Health Survey. The study participants were 18,824 older adults aged 65 years and over living alone. The data of the complex sample design was analyzed with consideration for weights, stratification, and clustering. Complex sample multiple logistic regression was conducted to identify factors associated with depression in older adults living alone during the COVID-19 pandemic.
Results: The results showed that the rate of depression in older adults living alone was 6.3%. Older adults living alone with decreased physical activity, decreased hours of sleep, and an increased or similar frequency of meeting with friends or neighbors were found to be more likely to have depression. In terms of factors related to the practice of COVID-19 infection prevention and control rules, not disinfecting regularly and not wearing a mask indoors were related to depression.
For health-related factors, fair or poor self-rated health status, not having breakfast every day, and feeling stressed were related to depression.
Conclusion: It is recommended to develop tailored interventions to prevent depression among older adults living alone by considering the factors related to their depression during the COVID-19 pandemic.

Purpose Untreated depression in adolescents affects their entire life. It is important to detect and intervene early depression in adolescence considering the characteristics of adolescent’s depressive symptoms accompanied by internalization and externalization. The aim of this study was to identify latent classes of depressive symptom trajectories of adolescents and determinants of classes in Korea.
Methods: The three time-point (2018~2020) data derived from the Korean Children and Youth Panel Survey 2018 were used (N=2,325). Latent Growth Curve Modeling (LGCM) was conducted to explore the depressive symptom trajectories in all adolescents, and Latent Class Growth Modeling (LCGM) was conducted to identify each latent class. Multinomial logistic regression analysis was performed to confirm the determinants of each latent class.
Results: The LGCM results showed that there was no statistically significant change in all adolescents' depressive symptoms for 3 years. However, the LCGM results showed that four latent classes showing different trajectories were distinguished: 1) Low-stable (intercept=14.39, non-significant slope), 2) moderate-increasing (intercept=19.62, significantly increasing slope), 3) high-stable (intercept=26.30, non-significant slope), and 4) high-rapidly decreasing (intercept=26.34, significantly rapidly decreasing slope). The multinomial logistic regression analysis showed that the significant determinants (i.e., gender, self-esteem, aggression, somatization, peer relationship) of each latent class were different.
Conclusion: When screening adolescent’s depression, it is necessary to monitor not only direct depression symptoms but also self-esteem, aggression, somatization symptoms, and peer relationships. The findings of this study may be valuable for nurses and policy makers to develop mental health programs for adolescents.

Purpose With the first generation of marriage-based immigrant women in East Asia now reaching their middle or old age, the need to focus investigations on their health-related quality of life has arisen. This study aimed to examine the extent to which physical and mental health, and psychosocial variables can predict health-related quality of life among Japanese middle-aged immigrant women.
Methods This study has a descriptive cross-sectional design. A convenience sample of 197 Japanese middle-aged marriage-based immigrant women from two regions of South Korea were recruited between December 2017 and March 2018. Participants completed self-administered questionnaires on health-related quality of life, menopausal symptoms, depression, perceived health status, disease morbidity, social support, and acculturation. The data were analyzed using hierarchical multiple regression.
Results Depression was the strongest predictor of health-related quality of life, followed by perceived health status, social support, and household income. Menopausal symptoms, presence of disease, and acculturation appeared to have no additional impact on participant’s health-related quality of life.
Conclusion In times of rapid growth of global migration and the aging of immigrants in new destination countries, nursing interventions and public health policies for aging marriage-based immigrant women should be prioritized to improve their mental health by facilitating social support and disease management. In addition, social and employment policies that can help immigrant women transition to a healthy midlife are needed.

Purpose The purpose of this study is to identify the factors affecting the life satisfaction during the communal life of the elderly in rural areas. Methods A total of 143 subjects were selected through convenient sampling. Data were collected in self-reporting questionnaires from 1 August to 30 August 2019. The data were analyzed with SPSS/WIN 23.0. Results The Instrumental Activities of Daily Living (IADL) was significantly different according to age, education, and cohabitation. Depression was significantly different according to gender, age, education, and cohabitation. Life satisfaction was significantly different according to age, education, religion, and cohabitation. There was a positive correlation between Instrumental Activities of Daily Living and depression, except for life satisfaction. 41.0% of life satisfaction was explained by depression, religion, and IADL. Conclusion The results of this study may be useful in understanding the life satisfaction level of elderly communal life and developing more specific programs for mental activity programs, and depression management strategies are required.

Purpose This study was to investigate the mediating effects of health concern and depression on the stress and fatigue of COVID-19 self-quarantine. Methods This was a cross-sectional study. A total of 227 people with COVID-19 self-quarantine experience were recruited during May 2021. Participants were invited to complete self-reported questionnaires that measure stress, health concern, depression, fatigue and demographic information. The data obtained were analyzed using multiple regression and dual mediation model applying the PROCESS macro with 95% bias-corrected bootstrap confidence interval. Results This study analyzed the direct effects of COVID-19 stress on the health concern, depression and fatigue. And COVID-19 stress had indirect effects on their fatigue via health concern and depression. Both health concern and depression had dual mediating effects in the influence of COVID-19 stress on fatigue. In the relationship between COVID-19 stress and fatigue, the mediating effect of depression was significant. Conclusion Fatigue due to prolonged COVID-19 can be alleviated by managing stress and mediating health concern and depression, and so therefore active nursing intervention is required.
Purpose The purpose of this study is to explore the roles and function of family in mediating the relationship between depression and quality of life of patients with Parkinson’s disease (PD). Most studies have found that depression is particularly common in patients with PD and further associated with poor quality of life. Family function, as a mediator, is based on a strength orientation perspective that emphasizes not only their responsibilities and risks but also recuperative powers and growth potential. Methods Overall 157 adults with idiopathic Parkinson’s disease were enrolled in this study via outpatient clinic and completed a set of assessment to measure depression using BDI, family APGAR questionnaire, and patients’ quality of life using PDQ-8. Hierarchical multiple regression analysis was conducted to examine the mediating role of family APGAR score in the relationship between BDI and PDQ-8. Results Patients' depression, gait disturbance, duration of illness, and family function were statistically significant on quality of life. These factors accounted for 60% of the variance in quality of life. Family function has a partial mediating effect on the relationship between depression and quality of life. Conclusion Findings from the study suggest that although PD patients' depression impacts their quality of life, by having strong family function, the extent to which depression impacts the quality of life can be favorably mitigated. Additionally, these outcomes have important implications for future model development regarding PD patients.

Purpose The purpose of this study was to examine the correlations among emotional perception clarity, emotion regulation, family relationship, non-suicidal self-injury, and depression, and to determine associated factors of non-suicidal self-injury and depression for senior elementary school students. Methods Data were collected from 150 early adolescences in K region, Korea. A self-report questionnaire consisted of Trait Meta-Mood Scale, Cognitive Emotion Regulation Questionnaire, Family Relationship Assessment Scale, Functional Assessment of Self-Mutilation, and Children's Depression Inventory. The data were analyzed using t-test, Pearson’s correlation coefficient, logistic regression, and multiple regression analysis. Results: Non-suicidal self-injury and depression were positively associated with maladaptive emotion regulation strategy and family conflict, but negatively related to emotional perception clarity and family support. Adaptive emotion regulation strategy and family togetherness were only significantly correlated with depression. In logistic regression analysis, significant predictors of non-suicidal self-injury were emotional perception clarity, maladaptive emotion regulation strategy, and family support. Multiple regression analysis found that significant factors of depression were adaptive and maladaptive emotion regulation strategies, which explained 38.0% of the variance. Conclusion Our study findings suggest that targeted intervention to reinforce the adaptive emotion regulation strategy and family relationship may prevent non-suicidal self-injury, and depression for senior elementary school students.

Purpose This study is a pseudo-experimental study of design before and after the non-equivalent control group, which was attempted to verify that the application of the ukulele to the elderly has the effects of reducing depression, improving self-efficacy, strengthening social bonding, and improving cognitive function. Methods 46 (23 in the experimental group and 23 in the control group) participants were selected. The experimental group was provided with three sessions of a music program using eight Ukuleles for the elderly, while the control group was provided with three sessions for the elderly. IBM SPSS 25.0 was used for data analysis, and the independent t-test, x2 -test, and Fisher's exact probability test were performed to verify the homogeneity of the subject's general characteristics.
The effect verification after the experimental treatment was analyzed by Fisher's exact probability test, Friedman test, and Mann-Whitney U test. Results Depression showed a statistically significant difference between the two groups (F=39.88, p<.001), self-efficacy showed a statistically significant difference between the two groups (z=-4.96, p<.001), social bonding showed a statistically significant difference between the two groups (z=-5.19, p<.001), and cognitive function showed a statistically significant difference between the two groups (z=-3.98, p<.001). Conclusion It was found that the ‘Music Program using the Ukulele’ was effective in reducing depression of the elderly, improving self-efficacy, reinforcing social bonding, and improving cognitive function. We hope that the Music Program using the Ukulele can be used in the elderly nursing curriculum in the future, and we suggest it should be applied as a nursing intervention to those who are experiencing cognitive decline.
Purpose This study was conducted to find out the association between dual-use of the electronic cigarette (EC) and conventional cigarette (CC) and depression among undergraduate students. Methods: The participants of this study were 225 undergraduate students who were attending two universities located in Ulsan metropolitan city. Descriptive statistics and multiple regression were conducted to analyze the data. Results Nicotine dependence and depression were significantly higher in the dual-use group than in the single-use group. Dual-use of the EC and CC was significantly associated with depression among undergraduate students. In addition, quality of sleep was significantly associated with depression among undergraduate students. Conclusion In order to prevent depression among undergraduate students, it is necessary to improve the awareness of the danger of dual use of the EC and CC.
