Ten-year trends in research designs and keywords: a bibliometric comparison of the Journal of Korean Academy of Nursing and leading international nursing journals
Year: 2025
Type: article
Abstract: Purpose: This study compared trends in research designs and keywords by analyzing the abstracts of four major nursing journals over the past decade, focusing on the Journal of Korean Academy of Nursing (JKAN) in comparison with the International Journal of Nursing Studies (IJNS), Journal of Advanced Nursing (JAN), and Japan Journal of Nursing Science (JJNS). Methods: A bibliometric analysis was conducted, encompassing 5,522 abstracts published between 2015 and 2024. Research designs were first classified as "quantitative," "qualitative," or "other," and then further sub-classified based on international evidence-based frameworks. Text preprocessing was also conducted, and term frequency-inverse document frequency was applied to evaluate keyword importance. The 2015-2019 and 2020-2024 periods were compared to examine changes in both research designs and keyword importance. Results: Compared to IJNS, JAN, and JJNS, JKAN published more instrument development and analytic studies but fewer randomized controlled trials and systematic reviews. Over time, the number of instrument development and mixed-methods studies in JKAN increased, while high-evidence designs remained scarce. Keyword analysis showed JKAN's emphasis on psychosocial themes such as self-efficacy, quality of life, and depression, whereas the other journals more often highlighted policy- and institution-related topics. Across journals, COVID-19 and patient safety emerged as important themes after 2020. Conclusion: JKAN demonstrates strengths in methodological diversity within quantitative research and in digital health-related analytics. However, high-evidence study designs and policy-oriented keywords are underrepresented in JKAN. Strategic expansion toward randomized controlled trials, systematic review, global and digital health, and policy-relevant research is recommended to strengthen JKAN's international competitiveness.
