Factors associated with Health-promoting Behaviors Among Nurses in South Korea: Systematic Review and Meta-analysis Based on Pender's Health Promotion Model.

PURPOSE: Although the importance of health promotion for nurses is increasing, there is a lack of meta-analyses targeting nurses in the world. This study aimed to identify the effect sizes between the health-promoting behaviors and related variables of nurses working in Korea METHODS: Systematic review and meta-analysis were conducted according to the PRISMA and MOOSE guidelines. The literature included in this meta-analysis was published between 1994 and 2022 in core databases such as KMbase, KISS, KoreaMed, ScienceON, DBpia, NAL, RISS, CINAHL, Cochrane, WoS, Pudmed, and hand searched. In this study, the PICO were The participants were nurses working in Korea, and for a more comprehensive search, intervention and comparisons were not set. The outcomes were nurses' health-promoting behaviors, and the study design included observational studies. The Comprehensive Meta-Analysis and the R software program were used for meta-analysis RESULTS: In total, 50 articles were selected for the systematic review and meta-analysis. The total effect size of the 50 articles was moderate (correlation effect size [ESr] = 0.30). The individual variables presented in the 50 articles were classified into nine sub-categories according to Pender's Health Promotion Model (HPM). Among them, situational influences demonstrated the largest effect size (ESr = 0.44, number of studies [k] = 2), followed by perceived self-efficacy (ESr = 0.39, k = 10) and activity-related affect (ESr = 0.32, k = 12) CONCLUSIONS: To achieve the optimal health status of nurses through health promotion intervention programs, these effective variables - situational influences, perceived self-efficacy, and activity-related affect - should be considered when developing the intervention program for nurses REGISTRATION: CRD42022299907.

[Factors Affecting Radiation Protective Behaviors in Perioperative Nurses Applying the Theory of Planned Behavior: Path Analysis].

PURPOSE: The aim of this study was to identify the factors explaining protective behaviors against radiation exposure in perioperative nurses based on the theory of planned behavior. METHODS: This was a cross-sectional study. A total of 229 perioperative nurses participated between October 3 and October 20, 2021. Data were analyzed using SPSS/WIN 23.0 and AMOS 23.0 software. The three exogenous variables (attitude toward radiation protective behaviors, subjective norm, and perceived behavioral control) and two endogenous variables (radiation protective intention and radiation protective behaviors) were surveyed. RESULTS: The hypothetical model fit the data (χ²/df = 1.18, SRMR = .02, TLI = .98, CFI = .99, RMSEA = .03). Radiation protective intention (ß = .24, p = .001) and attitude toward radiation protective behaviors (ß = .32, p = .002) had direct effects on radiation protective behaviors. Subjective norm (ß = .43, p = .002) and perceived behavior control (ß = .24, p = .003) had direct effects on radiation protective intention, which explained 38.0% of the variance. Subjective norm (ß = .10, p = .001) and perceived behavior control (ß = .06, p = .002) had indirect effects via radiation protective intention on radiation protective behaviors. Attitude toward radiation protective behaviors, subjective norm, and perceived behavioral control were the significant factors explaining 49.0% of the variance in radiation protective behaviors. CONCLUSION: This study shows that the theory of planned behavior can be used to effectively predict radiation protective behaviors in perioperative nurses. Radiation safety guidelines or education programs to enhance perioperative nurses' protective behaviors should focus on radiation protective intention, attitude toward radiation protective behaviors, subjective norm, and perceived behavioral control.

[National Petition Analysis Related to Nursing: Text Network Analysis and Topic Modeling].

PURPOSE: This study aimed to identify the main keyword, network structure, and main topics of the national petition related to "nursing" in South Korea. METHODS: Data were gathered from petitions related to the national petition in Korea Blue House related to the topic "nursing" or "nurse" from August 17, 2017, to May 9, 2022. A total of 5,154 petitions were searched, and 995 were selected for the final analysis. Text network analysis and topic modeling were analyzed using the Netminer 4.5.0 program. RESULTS: Regarding network characteristics, a density of 0.03, an average degree of 144.483, and an average distance of 1.943 were found. Compared to results of degree centrality and betweenness centrality, keywords such as "work environment," "nursing university," "license," and "education" appeared typically in the eigenvector centrality analysis. Topic modeling derived four topics: (1) "Improving the working environment and dealing with nursing professionals," (2) "requesting investigation and punishment related to medical accidents," (3) "requiring clear role regulation and legislation of medical and nonmedical professions," and (4) "demanding improvement of healthcare-related systems and services." CONCLUSION: This is the first study to analyze Korea's national petitions in the field of nursing. This study's results confirmed both the internal needs and external demands for nurses in South Korea. Policies and laws that reflect these results should be developed.

[Effects of Leadership Styles of Nursing Managers on Turnover Intention of Hospital Nurses: A Systematic Review and Meta-Analysis].

PURPOSE: This study aimed to examine effect sizes of leadership styles of nursing managers on turnover intention of hospital nurses. METHODS: A systematic review and meta-analysis were conducted in accordance with the PRISMA and MOOSE guidelines. Participants were nurses working in hospitals. The intervention involved nursing managers' leadership styles; the outcome assessed was nurses' turnover intention. This was an observational study design. Eleven databases were searched to obtain articles published in Korean or English. Of the 14,428 articles reviewed, 21 were included in systematic review and meta-analysis. Comprehensive Meta-Analysis and R software programs were used. RESULTS: The total effect size r (ESr) was -0.25 (95% confidence interval: -0.29 to -0.20). Effect sizes of each leadership style on turnover intention were as follows: ethical leadership (ESr = -0.34), transformational leadership (ESr = -0.28), authentic leadership (ESr = -0.23), transactional leadership (ESr = -0.21), and passive avoidant leadership (ESr = 0.13). Ethical leadership was the most effective style in decreasing turnover intention of hospital nurses. CONCLUSION: Positive leadership styles of nurse managers effectively decrease turnover intention of hospital nurses, and negative leadership styles of nurse managers effectively increase turnover intention of hospital nurses. The ethical leadership style is the most effective in decreasing turnover intention of hospital nurses; however, it requires careful interpretation as its effects are reported by only two studies. This study contributes to addressing the high turnover rate of hospital nurses and developing positive leadership styles of nurse managers in hospital settings.

[Patient Safety Management Activities of Korean Nurses: A Meta-Analytic Path Analysis].

PURPOSE: This study aimed to test a hypothetical model of Korean nurses' patient safety management activities using meta-analytic path analysis. METHODS: A systematic review, meta-analysis, and meta-analytic path analysis were conducted following the PRISMA and MOOSE guidelines. Seventy-four studies for the meta-analysis and 92 for the meta-analytic path analysis were included. The R software program (Version 3.6.3) was used for data analysis. RESULTS: Four variables out of 49 relevant variables were selected in the meta-analysis. These four variables showed large effect sizes (ESr = .54) or median effect sizes (ESr = .33~.40) with the highest k (number of studies) in the individual, job, and organizational categories. The hypothetical model for the meta-analytic path analysis was established using these variables and patient safety management activities. Twelve hypothetical paths were set and tested. Finally, the perception of the importance of patient safety management and patient safety competency directly affected patient safety management activities. In addition, self-efficacy, the perception of the importance of patient safety management, patient safety competency, and patient safety culture, indirectly affected patient safety management activities. CONCLUSION: Self-efficacy, the perception of the importance of patient safety management, patient safety competency, and the organization's patient safety culture should be enhanced to improve nurses' patient safety management activities.

[Images of Nurses Appeared in Media Reports Before and After Outbreak of COVID-19: Text Network Analysis and Topic Modeling].

PURPOSE: The aims of study were to identify the main keywords, the network structure, and the main topics of press articles related to nurses that have appeared in media reports. METHODS: Data were media articles related to the topic "nurse" reported in 16 central media within a one-year period spanning July 1, 2019 to June 30, 2020. Data were collected from the Big Kinds database. A total of 7,800 articles were searched, and 1,038 were used for the final analysis. Text network analysis and topic modeling were performed using NetMiner 4.4. RESULTS: The number of media reports related to nurses increased by 3.86 times after the novel coronavirus (COVID-19) outbreak compared to prior. Pre- and post-COVID-19 network characteristics were density 0.002, 0.001; average degree 4.63, 4.92; and average distance 4.25, 4.01, respectively. Four topics were derived before and after the COVID-19 outbreak, respectively. Pre-COVID-19 example topics are "a nurse who committed suicide because she could not withstand the Taewoom at work" and "a nurse as a perpetrator of a newborn abuse case," while post-COVID-19 examples are "a nurse as a victim of COVID-19," "a nurse working with the support of the people," and "a nurse as a top contributor and a warrior to protect from COVID-19." CONCLUSION: Topic modeling shows that topics become more positive after the COVID-19 outbreak. Individual nurses and nursing organizations should continuously monitor and conduct further research on nurses' image.

Nurses' ethical leadership and related outcome variables: Systematic review and meta-analysis.

AIM: To investigate the outcomes and the effect sizes of ethical leadership in nursing practice. BACKGROUND: Many meta-analysis of ethical leadership have been conducted in other fields, but there are none for the effects of ethical leadership of nurse leaders and should be investigated. EVALUATION: For a systematic literature review, we searched PubMed, EMBASE, the Cochrane Library, CINAHL, OVID, Web of Science and Korean databases for studies published in Korean or English. We used Comprehensive Meta-Analysis (CMA) 2.0 and R 3.6.2 for the meta-analysis. KEY ISSUES: We divided the outcomes of ethical leadership into three categories and investigated the effect sizes: subordinates' perceptions of their leaders (ES = 0.65), subordinates' ethical behaviours (ES = 0.04) and job or organisational outcomes (ES = 0.45). In addition, we identified 14 outcome variables, and transformational leadership showed the greatest effect size (ES = 0.77) among them. CONCLUSION: This study confirmed the positive effects of ethical nursing leadership on individual nurses' perceptions about their leaders, their jobs and organisations. IMPLICATIONS FOR NURSING MANAGEMENT: Nursing organisations and nurse administrators should make efforts to highlight ethical leadership of nurse leaders to improve outcomes of organisational performance including individual nurses' perceptions about their leaders, their jobs and organisations.

Academic Success of Online Learning in Undergraduate Nursing Education Programs in the COVID-19 Pandemic Era.

BACKGROUND: This study aimed to investigate predictors for academic success, including satisfaction with online class and academic achievement, in the coronavirus disease 19 (COVID-19) pandemic era. PURPOSE: To obtain basic data needed to improve the quality and outcomes of online learning in lectures for nursing students. METHOD: A cross-sectional, descriptive, nationwide online survey in South Korea was performed using structured questionnaires. Participants were 200 nursing students taking online-based learning at universities in 2020. Data were analyzed using descriptive statistics and hierarchical multiple regression with SPSS WIN 26.0 program. RESULTS: Cyber-class flow (ß = 0.65, p < 0.001) was a significant predictor of satisfaction with online class. Self-directed learning (ß = 0.18, p = 0.014) and satisfaction with online class (ß = 0.19, p = 0.035) were significant predictors of academic achievement. CONCLUSION: To achieve academic success from online learning, self-directed learning should be prioritized and satisfaction with online class needs to be managed by nursing educators. To improve satisfaction with online class, cyber-class flow should be considered when designing teaching and learning methods for undergraduate nursing education programs.

[Effects of Second Victim Experiences after Patient Safety Incidents on Nursing Practice Changes in Korean Clinical Nurses: The Mediating Effects of Coping Behaviors].

PURPOSE: This study was investigated the mediating effect of coping behaviors in the relationship between the second victim experiences after patient safety incidents and the nursing practice changes. METHODS: A cross-sectional survey was performed using structured questionnaires. Participants were 218 clinical nurses in general tertiary hospitals in South Korea. Data were collected through an online survey and snowball sampling from August 11 to September 6 2020. Data were analyzed using SPSS 23.0 program. A mediation analysis was performed using multiple regression and a simple mediation model applying the PROCESS macro with 95% bias-corrected bootstrap confidence interval. RESULTS: The mean scores of second victim experiences was 3.41/5. Approach coping (ß = .55, p < .001) and the avoidant coping (ß = - .23, p = .001) showed mediation effects in the relationship between second victim experiences and constructive change in nursing practice. Avoidant coping (ß = .29, p < .001) showed a mediation effect in the relationship between second victim experiences and defensive change in nursing practice. CONCLUSION: Coping behaviors has a mediating effect on the relationship between second victim experiences and nursing practice changes. To ensure that nurses do not experience second victim, medical institutions should have a culture of patient safety that employs a systematic approach rather than blame individuals. They also need to develop strategies that enhance approach coping and reducing avoidant coping to induce nurses' constructive practice changes in clinical nurses in experiencing second victims due to patient safety incidents.

Effects of nursing power and organizational trust on nurse's responsiveness and orientation to patient needs.

Aim: To assess the relationship among perceived nursing group power, organizational trust and patient orientation and identify patient orientation predictors. Background: Nurses and nursing organizations should use all resources to give care. Methods: Survey data were collected from 193 nurses at six acute care hospitals in South Korea. Characteristics of hospitals and nurses were analysed using t tests, one-way ANOVAs and regression models. Results: The means for perceived nursing group power, organizational trust and patient orientation were 3.71 (SD± 0.58), 3.22 (SD± 0.83) and 3.94 (SD± 0.53), respectively. Multiple regression analysis revealed that 40% of the variance in patient orientation was explained by perceived nursing group power, organizational trust and work experience. Conclusion: Hospitals should increase nursing group power and improve organizational trust to enhance patient orientation. Hospital executives and nurse managers should work to enhance nursing group power and positive perceptions of organizational trust, which could contribute to patient orientation.

[A Meta-Analytic Path Analysis on the Outcome Variables of Nursing Unit Managers' Transformational Leadership: Systemic Review and Meta-Analysis].

PURPOSE: The purpose of this study was to identify the outcome variables of nursing unit managers' transformational leadership and to test a hypothetical model using meta-analytic path analysis. METHODS: A systematic review and meta-analysis were conducted in accordance with PRISMA guidelines. Data analysis, conducted using R version 3.6.2 software, included 49 studies for the meta-analysis and 119 studies for meta-analytic path analysis. RESULTS: In the meta-analysis, four out of 32 outcome variables were selected. These four variables were empowerment, nursing performance, job satisfaction, and organizational commitment, which showed larger effect sizes than the median and more than five k. The hypothetical model for the meta-analytic path analysis was established by using these four variables and transformational leadership. A total of 22 hypothetical paths including nine direct effects and 13 indirect effects were set and tested. The meta-analytic path analysis showed that transformational leadership had direct effects on the four variables. Finally, eight direct effects, 12 indirect effects, and six mediating effects were statistically significant, and the hypothetical model was verified. CONCLUSION: Nursing unit managers can use the transformational leadership to improve empowerment, nursing performance, job satisfaction, and organizational commitment of nurses. This study empirically showed the importance of transformational leadership of nursing managers. This finding will be used as evidence to develop strategies for enhancing transformational leadership, empowerment, nursing performance, job satisfaction, and organizational commitment in nursing science and practice.

Long-term characteristics of soil respiration in a Korean cool-temperate deciduous forest in a monsoon climate.

Analysis of relationship between soil respiration and environmental factors has become essential for understanding changes in ecosystem carbon cycles under global warming. However, rough predictions have been made that soil respiration will increase with increasing temperature, but long-term data to support this theory were scarce. We measured soil respiration and environmental factors continuously using an automatic open-closed chamber system in a Korean cool-temperate forest from 2004 to 2016 to ascertain the reliability of this prediction and to more accurately predict changes in carbon cycle. Average air and soil temperatures were 11.0°C and 10.2°C. The increase in temperature was greater in winter (the inactive period for soil respiration) than in summer (the active period). Additionally, precipitation decreased sharply because of patter changes in 2012, and through 2016, it was approximately 69% of the previous period. Effect of precipitation on soil respiration was expected to be larger than temperature because the change in precipitation appeared in summer. Soil respiration exhibited a significant decline in 2012 because of precipitation. From 2004 to 2011, it averaged 344.4 mgCO2 m-2 h-1 and from 2012 to 2016 the average was 205.3 mgCO2 m-2 h-1. This phenomenon hasn't been detected in short-term studies, suggesting that the prediction of previous studies is inaccurate. Additionally, to predict future ecosystem carbon cycle changes in a cool-temperate monsoon climate, changes in precipitation pattern should be regarded as equally important to temperature, and the prediction cannot be based solely on temperature. Therefore, long-term and continuous measurements are needed with consideration of the effects of both precipitation and temperature. Abbreviations: Rs: soil respiration; Ts: soil temperature; Ta: air temperature; AOCC: automatic open/closed chamber.

Job autonomy, perceptions of organizational policy, and the safety performance of nurses.

AIMS: This study aimed to identify the relationship between nurses' job autonomy, perceptions of organizational policy, and safety performance by identifying the safety performance predictors of nurses working in acute health care settings in South Korea. METHODS: Using data from a structured questionnaire, this cross-sectional descriptive study assessed the relationship between nurses' job autonomy, perceptions of organizational policy, and safety performance. In 2016, of the 290 nurses from nine acute care hospitals in South Korea invited to participate in the survey, 254 successfully did. Using cross-sectional data, characteristics of hospitals and nurses were analysed with t tests, one-way analyses of variance, Pearson correlations, and regression models. RESULTS: On a scale of one to five, the mean job autonomy was 3.37, mean perceptions of organizational policy was 3.09, and mean safety performance was 3.75. Statistically significant positive correlations were found among job autonomy, perceptions of organizational policy, and safety performance. Multiple regression results found 44% of the variation in safety performance explained by job autonomy, length of employment, and perceptions of organizational policy. CONCLUSION: Job autonomy and perceptions of organizational policy were positively related to safety performance. Hospital executives and nurse managers should work to enhance job autonomy and positive perceptions of organizational policy, to contribute to improving patient safety.

[Types of Perception toward Ethical Issues in Perioperative Nurses: Q-Methodological Approach].

PURPOSE: This study was aimed at identifying the types of perceptions of ethical issues among perioperative nurses. METHODS: Q-methodology focusing on individual subjectivity was used with data collected in November 2016. Thirty-four Q-statements were selected and scored by the 35 participants on a 9-point scale with normal distribution. Participants were perioperative nurses working in advanced general hospitals and general hospitals. The data were analyzed using the PC-QUANL program. RESULTS: total of 35 perioperative nurses were classified into 4 factors based on the following viewpoints: self-centered (type 1), onlooking and avoiding (type 2), patient-centered (type 3), and problem-centered (type 4). The 4 factors accounted for 57.84% of the total variance. Individual contributions of factors 1, 2, 3, and 4 were 41.80%, 7.18%, 5.20%, and 3.66%, respectively. CONCLUSION: The major contribution of this study is the clarification of perioperative nurses' subjective perceptions of ethical issues. These findings can be used in formulating effective strategies for nursing educators, professional nurses, and nursing administrators to improve ethical decision-making abilities and to perform ethical nursing care by the appropriate management of ethical issues in everyday nursing practice.

[Life Experiences of Uninfected Women Living with HIV-Infected Husbands: A Phenomenological Study].

PURPOSE: This study aimed to understand the meaning and essence of the life experiences of uninfected women living with HIV-infected husbands. METHODS: This qualitative study adopted van Manen's hermeneutic phenomenological method. Study participants were 8 females whose husband had been diagnosed with HIV for longer than 6 months, who had known about their husband's infection for more than 6 months, who were in a legal or common-law marriage and were living with their husbands at the time of interview for this study, and whose HIV antibody test results were negative. Data were collected from in-depth individual interviews with the participants from May to August 2016, and from related idiomatic expressions, literature, artwork, and phenomenological references. RESULTS: The following essential themes were identified regarding the life experiences of uninfected women living with HIV-infected husbands: 'experiencing an abrupt change that came out of the blue and caused confusion', 'accepting one's fate and making desperate efforts to maintain one's family', 'dealing with a heavy burden alone', 'experiencing the harsh reality and fearful future', and 'finding consolation in the ordeal'. CONCLUSION: This study provided a holistic and in-depth understanding of the meaning and essence of the life experiences of uninfected women living with HIV-infected husbands. Thus, this study recognizes these unnoticed women as new nursing subjects. Further, the present findings can be used as important basic data for the development of nursing interventions and national policy guidelines for uninfected women living with HIV-infected husbands.

Health literacy and barriers to health information seeking: A nationwide survey in South Korea.

OBJECTIVE: To identify the level of health literacy and barriers to information seeking and to explore the predictors of health literacy. METHODS: A cross-sectional descriptive design was used. A total of 1000 Korean adults were recruited through proportional quota sampling. Health literacy, barriers to health information seeking, sociodemographics, and health-related characteristics were surveyed. Descriptive statistics and binary logistic regression were performed for data analysis. RESULTS: About 61% of participants were classified as inadequately health literate. "No health fairs/activities near home" was the most frequently reported barrier. Older age, lower education, living in the capital city, barriers regarding how to get information and access to expensive books and magazines were predictors of inadequate health literacy. CONCLUSION: Strategies for improving health literacy and reducing barriers to health information seeking should be designed. Education on how to access health-related information with easily accessible sources either free or inexpensive could be a way to help adults with limited health literacy. PRACTICE IMPLICATIONS: Health care professionals should assess clients' health literacy levels, particularly amongst those who are older or have less education. They should provide clients with information on how to access credible and readily available sources of health-related information, considering their health literacy level.

[Effects of Nursing Interventions for Fall Prevention in Hospitalized Patients: A Meta-analysis].

PURPOSE: The purpose of this study was to identify which nursing interventions are the most effective in fall prevention for hospitalized patients. METHODS: From 3,675 papers searched, 34 were selected for inclusion in the meta-analysis. Number of fallers, falls, falls per 1,000 hospital-days, and injurious falls, fall protection activity, knowledge related to falls, and self-efficacy about falls were evaluated as outcome variables. Data were analyzed using the Comprehensive Meta Analysis (CMA) 2.2 Version program and the effect sizes were shown as the Odd Ratio (OR) and Hedges's g. RESULTS: Overall effect size of nursing interventions for fall prevention was OR=0.64 (95% CI: 0.57~0.73, p<.05) and Hedges's g=-0.24. The effect sizes (OR) of each intervention ranged from 0.34 to 0.93, and the most effective nursing intervention was the education & environment intervention (OR=0.34, 95% CI: 0.28~0.42, p<.001), followed by education intervention (OR=0.57, 95% CI: 0.50~0.67, p=.001). Subgroup analyses showed that multifaceted interventions (OR=0.76, 95% CI: 0.73~0.79, p<.001) were more effective than unifactorial interventions, and that activities for prevention of falls (OR=0.08, 95% CI: 0.05~0.15, p<.001) showed the largest effect size among outcome variables. CONCLUSION: Falls in hospitalized patients can be effectively prevented using the nursing interventions identified in this study. These findings provide scientific evidence for developing and using effective nursing interventions to improve the safety of hospitalized patients.

[Effects of Blending Oil of Lavender and Thyme on Oxidative Stress, Immunity, and Skin Condition in Atopic Dermatitis Induced Mice].

PURPOSE: The purpose of this study was to evaluate the effects of essential oil on oxidative stress, immunity, and skin condition in atopic dermatitis (AD) induced mice. METHODS: This study was a 3×3 factorial design. Factors were oil type (Lavender, Thyme, and 2:1 mixture of lavender and thyme oil [blending oil]) and treatment period (0 day, 7 days, and 21 days). The samples were 45 mice with AD and randomly assigned to nine groups of five mice per group. The dependent variables such as superoxide radical, IgE, degranulated mast cells, and epidermal thickness were measured. Data were collected from February to April in 2014. Descriptive statistics, One-way ANOVA, Two-way ANOVA, and Tukey's HSD test were performed using the SPSS WIN 20.0 program. RESULTS: Dependent variables were not statistically significantly different by the three oil types (p>.05). Essential oils such as lavender, thyme, and blending oil were all effective in reducing AD symptoms and especially 2:1 blending oil were most effective. There were statistically significant differences by the three treatment periods in all dependent variables (p<.001). There were statistically significant interactions between oil types and treatment periods in all dependent variables (p<.01). For decreasing superoxide radical, degranulated mast cells, and epidermal thickness, 2:1 mixed oil should be applied for at least 21 days. Otherwise to reduce IgE, 2:1 mixed oil should be used for at least 7 days. CONCLUSION: These findings provide bases for developing effective interventions for AD patients to manage their AD symptoms.
