Seo, J.; Ko, H. Effects of Self-Leadership on Nursing Professionalism among Nursing Students: The Mediating Effects of Positive Psychological Capital and Consciousness of Calling. Healthcare 2024, 12, 1200. https://doi.org/10.3390/healthcare12121200

To provide high-quality nursing care, nursing education requires the basic quality of selfleadership from professional nurses so that they can make self-directed and responsible judgments and decisions. Therefore, this study aimed to investigate relationships among self-leadership, positive psychological capital, consciousness of calling, and nursing professionalism in nursing students. A

cross-sectional online survey of 202 students from two universities in South Korea was conducted between August and September 2022, using a convenience sampling method. A structured questionnaire was used to collect data. Data were analyzed using descriptive statistics, Pearson’s correlation coefficient analysis, and bootstrapping using Hayes’ PROCESS macro for mediation. A significant positive correlation was found between self-leadership, positive psychological capital, consciousness of calling, and nursing professionalism. Positive psychological capital and consciousness of calling showed an indirect mediating effect on the relationship between self-leadership and nursing professionalism. To improve nursing professionalism, programs should be developed to educate nursing students, strengthen their self-leadership skills, and increase the influence of positive psychological

capital and consciousness of calling for nursing. This will ultimately contribute to improving the quality of patient care by fostering competent nursing experts.

Advance directives (ADs) provide an opportunity for patients to enhance the quality of their end-of-life care and prepare for a dignified death by deciding treatment plans. The purpose of this study was to explore the multiple

factors that influence the advance directives completion among older adults in South Korea.

This was a secondary analysis of a cross-sectional study of 9,920 older adults. The differences in ADs based on subjects’ sociodemographic characteristics, health-related characteristics, and attitude toward death were

tested using the chi-squared and t-test. A multinomial logistic regression model was used to identify the influencing factor of ADs.

The number of chronic diseases, number of prescribed medications, depression, insomnia, suicide intention, and hearing, vision, or chewing discomfort were higher in the ADs group compared to the non-ADs group. The

influencing factors of the signing of ADs included men sex, higher education level, exercise, death preparation education, lower awareness of dying-well, and experience of fracture.

Information dissemination regarding ADs should be promoted and relevant authorities should consider multiple options to improve the physical and psychological health of older adults, as well as their attitude toward death

to increase the ADs completion rate.

Myung Jin, J. A. N. G., M. K. H.,  M. J. L., K. A. L., Y. O. K., J. A. J., & H. K. (2024). Effect of Counting Error Prevention Training on Operating Room Nurses’ Counting Error Prevention Awareness and Perceptions of Patient Safety.Korean J Health Promot 2024;24(1):20-28 pISSN: 2234-2141 • eISSN: 2093-5676 https://doi.org/10.15384/kjhp.2024.00024

Background: This study aimed to identify changes in counting error prevention awareness and patient safety perception through

counting error prevention education to operating room nurses.

Methods: This was a one-group, pretest-posttest, quasi-experimental study. The participants were operating room nurses. A total of

46 nurses were recruited, and data was collected between October 1 and 31, 2022. Measures used for this study assessed counting

error prevention awareness and patient safety perception. The data were analyzed using paired t-tests.

Results: The counting error prevention awareness of the participants increased significantly from 3.68 to 3.95 points before and after

education, respectively (t=–5.07, P<0.001), while patient safety perception significantly increased from 3.95 to 4.20 points before and after training, respectively (t=–2.68, P=0.010).

Conclusions: Counting error prevention awareness and patient safety perception of operating room nurses prevent fatal damage to

patients with surgeries and lower mortality. The results of this study suggest the necessity of various education methods to reduce

medical accidents among surgical patients and to raise patient safety perception for operating room nurses.

Changes in the health status and health-related quality of life of community-dwelling older adults living alone: one-year follow-up from a cohort study

Ko H, Cho B, Lim K-C, Jang S-N, Chang SJ, Yi YM, Cho HR, Ryu SI, Noh E-Y and Park Y-H(2023) Changes in the health status and health-related quality of life of communitydwelling older adults living alone: one-year follow-up from a cohort study. Front. Public Health 11:1278008.doi: 10.3389/fpubh.2023.1278008

The Time differences were observed in the subjective evaluation of health status (SEH), IPAQ scores, frailty, nutritional status, and depression. Gender differences were observed in the SEH, IPAQ, frailty, loneliness, depression, and social support. The interaction between time and gender was observed in the IPAQ and HRQoL. At baseline, SEH, depressive symptoms, gender, frailty, and age were associated with HRQoL. After one year, HRQoL was associated with SEH, frailty, depressive symptoms, cost of living, suicidal thoughts, gender, social support, loneliness, and suicide attempts.

Our results highlight that HRQoL is associated with physical health, mental health, and social support. Future detailed studies are needed to determine whether governments and communities can prevent depression, loneliness, and suicidal thoughts through psychological support and provide economic support to improve the quality of life of older adults living alone.

Ko, H., & Jung, S. (2023). Development and Analysis of the Job Description for Dementia Care Center Nurses in Korea Using Developing a Curriculum (DACUM). Journal of Gerontological Nursing, 49(10), 29-35. 

The current study aimed to develop and analyze a dementia care center nurse (DCCN) job description using Developing a Curriculum (DACUM) in Korea. Seven DCCN panels participated in the DACUM workshop to define the duties and tasks.

The developed duties and tasks were validated with a survey that included the importance, diffi culty, frequency, and educational needs of the duties and tasks. Descriptive statistics were used to analyze the data collected from August to September

2020. Nine duties and 111 tasks were identifi ed, with “dementia screening” ranking the highest among the duties and “management of cognitive programs” ranking the lowest. The task with the highest rank based on the determinant coefficient and educational needs was “conducting the fi rst stage of the diagnostic test,” whereas the task with the lowest rank was “recording special issues.” Findings can be used as fundamental data for designing educational programs aimed at enhancing the competencies of DCCNs and as a tool for evaluating their job performance.

Social Frailty among Community-Dwelling Older Adults during the COVID-19 Pandemic in Korea: A Cross-Sectional Study

Choi, S.; Ko, H. Social Frailty among Community-Dwelling Older Adults during the COVID-19 Pandemic in Korea: A Cross-Sectional Study. Int. J. Environ. Res. Public Health 2022, 19, 11963. https://doi.org/10.3390/ijerph191911963

Social frailty among older adults has become a growing concern from a public health perspective in the context of the coronavirus disease 2019 (COVID-19) pandemic. This study’s aim was to investigate the influence of various aspects of social frailty in community-dwelling older adults during the COVID-19 pandemic. This study carried out a secondary analysis of data collected from the 2020 National Survey of Older Koreans and performed multinomial logistic regression analysis to identify the predictive factors of social frailty. The affected factors for the social frailty group were health conditions (depression), behavioral and metabolic risk factors (exercise, nutritional status, current smoking status, drinking frequency), intrinsic capacity (cognitive functions, activities of daily living), and digital literacy (use of smartphone or tablet PCs). Since multidimensional factors could affect older adults’ social frailty, comprehensive strategies are urgently needed to reduce their rate of social frailty.

Aims We aim to identify challenges and recommendations for senior centre health services focusing on nurses' roles in an urban South Korean community. Background Senior centres can potentially provide easily accessible and cost-effective health services to older adults. It is essential to identify current challenges to improve health services. Method This study used an explanatory sequential mixed-methods design. Quantitative descriptive data were obtained from a survey of all nurses at senior centres in Seoul (n = 30). For the qualitative data, focus group interviews were conducted with various senior centre stakeholders (n = 15). Results Two main themes, discrepancy between services and needs and reform senior centres, were identified with six subthemes. Conclusions Challenges identified included insufficient availability to meet health service needs, overlapping health services, and no legal clarification of nurses' roles. Recommendations to improve the senior centre health services include to focus on the centres' main goals, function as health and welfare hubs, establish legal guidelines, and provide adequate nurse staffing. Implication for Nursing Management The senior centres need to hire more nurses and define nurses' occupational roles legally for the centres to serve as a hub connecting medical care and welfare.

Kim, J. Y., Tak, S. H., Ko, H., Jung, S., Lee, J., & Choi, H. (2022). Effects of a 6-Week Integrated Dementia Awareness and Prevention Program for Community-Dwelling Older Adults. SAGE Open, 12(3), 21582440221123503. 

Older adults show a lack of knowledge about dementia, treatments, and management although they are fearful of developing

dementia. The purpose of this study was to examine the effects of a 6-week intervention on knowledge, attitude, fear, and

prevention behaviors concerning dementia among older adults who resided in community. The study used a pretest-posttest

design with nonequivalent control group. A total of 40 participants completed the study. The intervention group showed a

significant decrease in the fear of dementia scores compared to the control group after the intervention(p < .05). However,

no significant differences were found between the groups with respect to knowledge, attitude toward dementia, and healthy

prevention behaviors. The intervention may be effective in decreasing older adults’ negative emotions concerning dementia,

particularly, fear. The assessment of the fear toward dementia may help identify individual causes and triggers and provide

tailored interventions.
