Development and Evaluation of Evidence-Based Nursing Protocol for Extracorporeal Membrane Oxygenation to Critically Ill Patients: Kim, Soomi , Kim, Chul-Gyu; J Korean Acad Nurs 2023;53(3):275-294. Published online June 30, 2023; DOI: https://doi.org/10.4040/jkan.22109

Abstract PDF: Purpose
This study aimed to develop an evidence-based extracorporeal membrane oxygenation (ECMO) nursing protocol for critically ill patients receiving ECMO treatment by using an adaptation process, and to verify the effects of the protocol.
Methods
The protocol was developed according to the adaptation guidelines. A non-randomized controlled trial was conducted to test the protocol’s effects. Data were collected between April 2019 and March 2021. The differences in physiological indicators and complication rates between the two groups were investigated using a chart review to evaluate patient outcomes. The nurses’ outcome variables were evaluated using a questionnaire.
Results
First, after reviewing 11 guidelines by appraisal of the guidelines for research and evaluation collaboration II, 5 guidelines with a standardization grade of over 50 points were selected. An ECMO nursing protocol was developed based on these guidelines. Second, there were no statistically significant differences in physiological indicators between the two groups of patients. However, the experimental group showed a statistically significant decrease in the infection rate (p = .026) and pressure injury rates (p = .041). The levels of satisfaction with ECMO nursing care, and empowerment and performance of the nurses who used the ECMO nursing protocol were higher than those of nurses who did not (p < .001).
Conclusion
This protocol may help prevent infections and pressure injuries in patients, and improve nurses’ satisfaction and empowerment. The nursing protocol developed for critically ill patients receiving ECMO treatment can be utilized in evidence-based nursing practice.

Psychometric Properties of the Korean Version of Self-Efficacy for HIV Disease Management Skills: Kim, Gwang Suk , Kim, Layoung , Shim, Mi-So , Baek, Seoyoung , Kim, Namhee , Park, Min Kyung , Lee, Youngjin; J Korean Acad Nurs 2023;53(3):295-308. Published online June 30, 2023; DOI: https://doi.org/10.4040/jkan.23016

Purpose
This study evaluated the validity and reliability of Shively and colleagues’ self-efficacy for HIV disease management skills (HIVSE) among Korean participants.
Methods
The original HIV-SE questionnaire, comprising 34 items, was translated into Korean using a translation and back-translation process. To enhance clarity and eliminate redundancy, the author and expert committee engaged in multiple discussions and integrated two items with similar meanings into a single item. Further, four HIV nurse experts tested content validity. Survey data were collected from 227 individuals diagnosed with HIV from five Korean hospitals. Construct validity was verified through confirmatory factor analysis. Criterion validity was evaluated using Pearson’s correlation coefficients with the new general self-efficacy scale. Internal consistency reliability and test-retest were examined for reliability.
Results
The Korean version of HIV-SE (K-HIV-SE) comprises 33 items across six domains: “managing depression/mood,” “managing medications,” “managing symptoms,” “communicating with a healthcare provider,” “getting support/help,” and “managing fatigue.” The fitness of the modified model was acceptable (minimum value of the discrepancy function/degree of freedom = 2.49, root mean square error of approximation = .08, goodnessof-fit index = .76, adjusted goodness-of-fit index = .71, Tucker-Lewis index = .84, and comparative fit index = .86). The internal consistency reliability (Cronbach’s α = .91) and test-retest reliability (intraclass correlation coefficient = .73) were good. The criterion validity of the K-HIV-SE was .59 (p < .001).
Conclusion
This study suggests that the K-HIV-SE is useful for efficiently assessing self-efficacy for HIV disease management.

A Structural Equation Model for Posttraumatic Growth among Cured Patients with COVID-19: An, Soo Young , Choi, Heejung; J Korean Acad Nurs 2023;53(3):309-323. Published online June 30, 2023; DOI: https://doi.org/10.4040/jkan.22118

Abstract PDF: Purpose
This study aimed to develop and test a model for posttraumatic growth among cured patients with COVID-19. This model was based on Calhoun and Tedeschi’s Posttraumatic Growth model and a literature review.
Methods
The participants comprised 223 patients cured from COVID-19 who were ≥ 19 years of age. The data were collected through an online questionnaire from March 21 to 24, 2022. The assessment tools included the Impact of Event Scale: Revised Korean version, the Connor-Davidson Resilience Scale, the Distress Dis-closure Index, the Multidimensional Scale of Perceived Social Support, the Korean version of the Event-related Rumination Inventory, and the Korean version of the Post-traumatic Growth Inventory. Data were analyzed using the IBM SPSS version 24.0 and IBM AMOS 26.0.
Results
The modified model showed appropriate goodness of fit (χ 2 = 369.90, χ 2 /degree of freedom = 2.09, SRMR = .09, RMESA = .07, CFI = .94, TLI = .93). The post-traumatic growth of cured patients with COVID-19 was explained through distress perception, self-disclosure, and deliberate rumination, with the explanatory power being 70.0%.
Conclusion
This study suggests preparing a disaster psychology program involving experts who can activate deliberate rumination is necessary. Further, this study may serve as basic data for developing a program to enhance the post-traumatic growth of patients cured from COVID-19.

The Reliability and Validity of the Korean Version of the 5C Psychological Antecedents of Vaccination Scale: Bae, SuYeon , Kim, HeeJu; J Korean Acad Nurs 2023;53(3):324-339. Published online June 30, 2023; DOI: https://doi.org/10.4040/jkan.23021

Abstract PDF

Purpose
This study aimed to valuate the reliability and validity of the Korean version of the 5C Psychological Antecedents of Vaccination (K-5C) scale.
Methods
The English version of the 5C scale was translated into Korean, following the World Health Organization guidelines. Data were collected from 316 community-dwelling adults. Content validity was evaluated using the content validity index, while construct validity was evaluated through confirmatory factor analysis. Convergent validity was examined by assessing the correlation with vaccination attitude, and concurrent validity was evaluated by examining the association with coronavirus disease 2019 (COVID-19) vaccination status. Internal consistency and test-retest reliability were also evaluated.
Results
Content validity results indicated an item-level content validity index ranging from .83 to 1, and scale-level content validity index, averaging method was .95. Confirmatory factor analysis supported the fit of the measurement model, comprising a five-factor structure with a 15-item questionnaire (RMSEA = .05, SRMR = .05, CFI = .97, TLI = .96). Convergent validity was acceptable with a significant correlation between each sub-scale of the 5C scale and vaccination attitude. In concurrent validity evaluation, confidence, constraints, and collective responsibility of the 5C scale were significant independent predictors of the current COVID-19 vaccination status. Cronbach’s alpha for each subscale ranged from .78 to .88, and the intraclass correlation coefficient for each subscale ranged from .67 to .89.
Conclusion
The Korean version of the 5C scale is a valid and reliable tool to assess the psychological antecedents of vaccination among Korean adults.

Abstract PDF

Purpose
This study aimed to develop an instrument to showcase Dignity in Care of Terminally Ill Patients for Nurses and to examine its validity and reliability.
Methods
A total of 58 preliminary items on dignity in care of terminally ill patients for nurses were selected using content validity analysis and expert opinions on 97 candidate items derived through a literature review and qualitative focus group interviews. Questionnaires were administered to 502 nurses caring for terminally ill cancer patients at hospice and palliative care institutions. The data were analyzed using item analysis, exploratory and confirmatory factor analysis, convergent and discriminant validity, and Pearson correlation for criterion validity, reliability was tested using Cronbach’s alpha.
Results
The final instrument consisted of 25 items, with four factors identified through confirmatory factor analysis. Four factors-ethical values and moral attitudes, interaction-based communication, main-taining comfort, professional insight and competence–accounted for 61.8% of the total variance. Cronbach’s ⍺ for total items was .96, and test-retest reliability of intraclass correlation coefficient was .90.
Conclusion
Since its validity and reliability have been verified through various methods, the Dignity in Care Scale of Terminally Ill Patients for Nurses can be used for develop nursing interventions and improve dignity in care of terminally ill patients.

Internal Structure of the Health-Related Quality of Life Instrument with 8-Items in a Nationally Representative Population: Lee, Eun-Hyun; J Korean Acad Nurs 2023;53(3):359-369. Published online June 30, 2023; DOI: https://doi.org/10.4040/jkan.23007

Abstract PDF

Purpose
This study evaluated the internal structure (structural validity, internal consistency, and measurement invariance) of the Health-Related Quality of Life Instrument with Eight Items (HINT-8), developed to measure Korean people’s health-related quality of life.
Methods
A secondary analysis was conducted using data from the Korea National Health and Nutrition Examination Survey, involving 6,167 adults aged over 18 years. The structural validity of the HINT-8 was assessed using exploratory graph analysis and confirmatory factor analysis. Internal consistency and measurement invariance were analyzed using McDonald’s omega (ω) and multigroup confirmatory factor analysis, respectively.
Results
The HINT-8 had a single dimension and good internal consistency (ω = .804). The one-dimension HINT-8 ex-hibited matric invariance but not scalar invariance across sociodemographic groups (sex, age, education, and marital status). Further, it exhibited scalar or partial scalar invariance across medical condition groups (hypertension, diabetes, depressive symptoms, and cancer).
Conclusion
The study finds that the HINT-8 demonstrated satisfactory structural validity and internal consistency, indicating its suitability for practice and research. However, the HINT-8 scores cannot be compared across different groups regarding sex, age, education, and marital status, as the interpretation varies within each sociodemographic category. Conversely, interpretation of the HINT-8 is consistent for individuals with and without hypertension, diabetes, depressive symptom, and cancer.
