Purpose: This study aimed to analyze professional grief and related concepts in terminal care among intensive care unit nurses and propose a tentative conceptualization of professional complicated grief. Methods: Rodgers' evolutionary concept analysis was applied. International and Korean databases were searched for studies published from January 1995 to January 2026. Twenty-two studies were included and classified as core intensive care unit evidence, related critical care evidence, or broader contextual evidence. Results: Professional grief, nurses’ grief, and occupational grief were identified as overlapping terms, whereas professional bereavement, complicated grief, prolonged grief disorder, and pandemic grief were related concepts. Antecedents included repeated patient deaths, terminal and after-death care, caring relationships, insufficient organizational support, and professional role expectations. Five attributes were identified: persistence and reactivation, cumulativeness, multidimensional complexity, grounding in professional caring relationships, and restricted emotional expression and disenfranchisement. Consequences included psychological distress, burnout, adverse work-related outcomes, avoidance or emotional distancing, meaning reconstruction and professional growth, and organizational recognition and support needs. Here, complicated denotes the interwoven temporal, cumulative, multidimensional, relational, and organizational characteristics of grief rather than psychiatric severity or functional impairment. Conclusion: Professional complicated grief is a tentative nursing concept requiring qualitative validation and expert review before measurement and intervention development.

Purpose: This study aimed to translate the revised Moral Sensitivity Questionnaire (MSQ-R) into Korean and evaluate the validity and reliability of the Korean version (KMSQ-R) among clinical nurses. Methods: A methodological study was conducted with 261 clinical nurses in Korea. Construct validity was evaluated using exploratory factor analysis. Concurrent validity was examined using the Korean Moral Sensitivity Questionnaire (K-MSQ), and discriminant validity was assessed using a bioethical awareness scale. Reliability was evaluated using Cronbach’s α and the intraclass correlation coefficient (ICC). Results: Exploratory factor analysis identified a three-factor structure that differed from the original version. Concurrent validity was confirmed through a significant correlation with the K-MSQ (r=.46, p<.001) and discriminant validity was supported (r=.03, p=.63). The KMSQ-R demonstrated acceptable internal consistency (Cronbach’s α=.74) and test-retest reliability (ICC=.67). Conclusion: The KMSQ-R is a valid and reliable instrument for assessing moral sensitivity among Korean clinical nurses. Its concise structure supports its practical application in clinical practice, ethics education, and future research.

Purpose: This study aimed to identify the factors influencing nurse–patient interaction, with a particular focus on communication competence and self-efficacy, among clinical nurses working at a tertiary hospital. Methods: A descriptive correlational study was conducted with 178 nurses who had at least one year of clinical experience and were working in general wards at a tertiary hospital in Seoul, South Korea. Data were collected using structured questionnaires and analyzed using hierarchical multiple regression analysis. Results: The mean scores on a 5-point scale were 4.04±0.40 for nurse–patient interaction, 3.95±0.39 for communication competence, and 3.94±0.49 for self-efficacy. Hierarchical multiple regression analysis showed that clinical experience of 15 years or more (β=.47, p<.001), communication competence (β=.33, p<.001), and self-efficacy (β=.25, p<.001) were significant factors influencing nurse–patient interaction. The final regression model explained 41.0% of the variance in nurse–patient interaction. Conclusion: Communication competence, self-efficacy, and extensive clinical experience were important factors influencing nurse–patient interaction. These findings suggest the need to develop tailored educational programs that strengthen nurses’ communication competence and self-efficacy to promote effective nurse–patient interaction and patientcentered nursing care.

Purpose: This study analyzed post-publication corrections and retractions in an international nursing journal to reaffirm research ethics guidelines through representative cases. Methods: A case analysis was conducted on all Erratum, Corrigendum, and Retraction notices published in the journal from January 2021 to December 2025. Each notice was compared with its original article, and cases were inductively classified into six categories through independent coding and cross-review. Frequencies were calculated with multiple counting of reasons, and representative cases were qualitatively reviewed against the KIRD standard curriculum and COPE guidelines. Results: Twenty-nine notices were issued, while 826 research and review articles were published over the same period. Corrigenda accounted for 25 (86.2%), Errata for 3 (10.3%), and Retractions for 1 (3.4%). The most common corrigenda involved author and administrative information (44.0%) and data entry errors (40.0%). Most corrections resulted from carelessness in recording and verification rather than misconduct, whereas the single retraction involved discrepancies between the registered protocol and the published trial. Conclusion: Responsible self-correction through prompt acknowledgment, transparent disclosure, and formal correction is essential for research integrity. To prevent errors, systematic self-checking by authors before submission, verification of trial registration during peer review and editing, and practice-oriented research ethics education are recommended.
