Purpose: This study was conducted to analyze trends in research papers published in the Journal of Korean Public Health Nursing, and to compare and contrast similarities and differences of papers before and after listing in the Korea Citation Index (KCI) in 2007. Methods: A descriptive study was conducted with 266 published studies during the 10-year period. The criteria for analysis included types of research, characteristics of researchers and participants, designs, data collection methods and study instruments, ethical considerations, data analysis, and keywords. Results: Studies conducted with grants constituted 23.7%, and students (32.3%) and general populations (25.2%) comprised the largest proportion of the study participants. The majority of the papers were quantitative research (93.2%), and self-reported methods (63.1%) were most frequently utilized. Seventy percent of the studies obtained verbal consent from the participants. Among the study instruments, psychosocial indicators (41.1%) were most frequently employed. The trends indicated that grant studies, students and general populations as study participants, and experimental studies increased, and use of written consent increased after KCI registration. Conclusions: The results could be used to understand the context of scientific research and to improve the quality of the research papers published in the Journal of Korean Public Health Nursing.
