An evaluation of STROBE reporting compliance in cross-sectional studies published in the Journal of Korean Biological Nursing Science (2011–2024): a methodological review

Purpose: This study aimed to evaluate item-level reporting compliance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist among cross-sectional studies published in the Journal of Korean Biological Nursing Science (JKBNS) between 2011 and 2024, and to identify both strengths and gaps in reporting practices. Methods: A descriptive methodological review was conducted. Using the official JKBNS online archive, 192 cross-sectional survey studies published between 2011 and 2024 were identified and included in the analysis. Reporting compliance was evaluated using the STROBE checklist, and item-level mapping was performed between STROBE items and the Joanna Briggs Institute and National Institutes of Health (NIH) critical appraisal critical appraisal tools. Results: The mean overall STROBE compliance rate was 74.0%. Reporting of study objectives, outcome data, and interpretation was generally adequate across the included studies. However, substantial deficiencies were observed in the Methods domain. In particular, sample size justification, reporting of bias, handling of missing data, description of sampling strategies, sensitivity analyses, and inclusion of participant flow diagrams were rarely reported. Conclusion: The reporting quality of cross-sectional studies published in JKBNS was moderate, with notable weaknesses in methodological transparency. These deficiencies may limit the interpretability and applicability of research findings in nursing practice and policy contexts. Systematic and explicit application of the STROBE reporting guidelines, supported by guideline-based education and strengthened editorial policies, is essential for improving reporting transparency and methodological rigor in nursing research.
