Purpose This study investigated the relationship of the partnership between nurses and parents of hospitalized children with the quality of pediatric nursing care as perceived by pediatric nurses. Methods A cross-sectional descriptive study was conducted among 90 nurses. The data collected were analyzed using the independent t-test and the Pearson correlation coefficient. Results The level of partnership between nurses and parents showed significant differences by nurses’ age (t=2.22, p=.029) and marital status (t=2.54, p=.013). The quality of pediatric nursing care was found to significantly differ by the nurses’ age (t=2.62, p=.013), marital status (t=4.17, p<.001), whether nurses had children (t=2.53, p=.020), pediatric ward work experience (t=2.43, p=.020), and total work experience (t=2.51, p=.016). The level of partnership between nurses and parents was positively correlated with the quality of pediatric nursing care (r=.48, p<.001). Conclusion To improve the quality of nursing care for hospitalized children and their parents, it is important to consider the specific characteristics of pediatric nurses, whose clinical skills should be improved.
